For report-only mode, use /qa-only. (gstack)\n- qa-only: Report-only QA testing. Systematically tests a web application and produces a\nstructured report with health score, screenshots, and repro steps — but never\nfixes anything. Use when asked to \"just report bugs\", \"qa report only\", or\n\"test but don't fix\". For the full test-fix-verify loop, use /qa instead.\nProactively suggest when the user wants a bug report without any code changes. (gstack)\n- retro: Weekly engineering retrospective. Analyzes commit history, work patterns,\nand code quality metrics with persistent history and trend tracking.\nTeam-aware: breaks down per-person contributions with praise and growth areas.\nUse when asked to \"weekly retro\", \"what did we ship\", or \"engineering retrospective\".\nProactively suggest at the end of a work week or sprint.

Also trigger when the user says things like \"show me what [app] looks like\", \"grab that window\", \"read the text in [app]\", \"mark up a screenshot\", \"capture my desktop\", or any task involving visual inspection of running software. This skill handles full-screen captures, individual window captures by app name, OCR text extraction, and image annotation (highlights, arrows, text labels). Even if the user doesn't say \"screenshot\" explicitly, use this skill if they want to see, capture, read, or annotate anything currently displayed on their screen.\n- setup-browser-cookies: Import cookies from your real Chromium browser into the headless browse session.\nOpens an interactive picker UI where you select which cookie domains to import.\nUse before QA testing authenticated pages.

Use when you want to widen edit scope without ending the session.\nUse when asked to \"unfreeze\", \"unlock edits\", \"remove freeze\", or\n\"allow all edits\". (gstack)\n- win-marketplace-add: Add a plugin marketplace on Windows, bypassing the EBUSY rename bug. Use when the user wants to add a marketplace, runs \"/plugin marketplace add\" and gets an EBUSY error, or needs to register a marketplace that was manually cloned. Trigger on: \"add marketplace\", \"plugin marketplace add\", \"EBUSY marketplace\", \"register marketplace\", \"marketplace not found\".\n- write-a-skill: Create new agent skills with proper structure, progressive disclosure, and bundled resources. Use when user wants to create, write, or build a new skill.\n- ccs: Delegate task with intelligent profile selection [AUTO ENHANCE]\n- ccs:continue: Continue last CCS delegation session [AUTO ENHANCE]\n- deep-research: Deep research harness — fan-out web searches, fetch sources, adversarially verify claims, synthesize a cited report. - When the user wants a deep, multi-source, fact-checked research report on any topic. BEFORE invoking, check if the question is specific enough to research directly — if underspecified (e.g., \"what car to buy\" without budget/use-case/region), ask 2-3 clarifying questions to narrow scope. Then pass the refined question as args, weaving the answers in.\n- frontend-design:frontend-design: Guidance for distinctive, intentional visual design when building new UI or reshaping an existing one. Helps with aesthetic direction, typography, and making choices that don't read as templated defaults.\n- spt:clear-psyche: Clear stored Psyche context.

Automated behaviors (\"from now on when X\", \"each time X\", \"whenever X\", \"before/after X\") require hooks configured in settings.json - the harness executes these, not Claude, so memory/preferences cannot fulfill them. Also use for: permissions (\"allow X\", \"add permission\", \"move permission to\"), env vars (\"set X=Y\"), hook troubleshooting, or any changes to settings.json/settings.local.json files. Examples: \"allow npm commands\", \"add bq permission to global settings\", \"move permission to user settings\", \"set DEBUG=true\", \"when claude stops show X\". For simple settings like theme/model, suggest the /config command.\n- keybindings-help: Use when the user wants to customize keyboard shortcuts, rebind keys, add chord bindings, or modify ~/.claude/keybindings.json. Examples: \"rebind ctrl+s\", \"add a chord shortcut\", \"change the submit key\", \"customize keybindings\".\n- verify: Verify that a code change actually does what it's supposed to by running the app and observing behavior. Use when asked to verify a PR, confirm a fix works, test a change manually, check that a feature works, or validate local changes before pushing.\n- code-review: Review the current diff for correctness bugs and reuse/simplification/efficiency cleanups at the given effort level (low/medium: fewer, high-confidence findings; high→max: broader coverage, may include uncertain findings; ultra: deep multi-agent review in the cloud). Pass --comment to post findings as inline PR comments, or --fix to apply the findings to the working tree after the review.\n- simplify: Review the changed code for reuse, simplification, efficiency, and altitude cleanups, then apply the fixes. Quality only — it does not hunt for bugs; use /code-review for that.\n- fewer-permission-prompts: Scan your transcripts for common read-only Bash and MCP tool calls, then add a prioritized allowlist to project .claude/settings.json to reduce permission prompts.\n- loop: Run a prompt or slash command on a recurring interval (e.g. /loop 5m /foo). Omit the interval to let the model self-pace. - When the user wants to set up a recurring task, poll for status, or run something repeatedly on an interval (e.g. \"check the deploy every 5 minutes\", \"keep running /babysit-prs\"). Do NOT invoke for one-off tasks.\n- schedule: Create, update, list, or run scheduled cloud agents (routines) that execute on a cron schedule. - When the user wants to schedule a recurring cloud agent, set up automated tasks, create a cron job for Claude Code, or manage their scheduled agents/routines. Also use when the user wants a one-time scheduled run (\"run this once at 3pm\", \"remind me to check X tomorrow\").\n- claude-api: Reference for the Claude API / Anthropic SDK — model ids, pricing, params, streaming, tool use, MCP, agents, caching, token counting, model migration.\nTRIGGER — read BEFORE opening the target file; don't skip because it \"looks like a one-liner\" — whenever: the prompt names Claude/Anthropic in any form (Claude, Anthropic, Fable, Opus, Sonnet, Haiku, `anthropic`, `@anthropic-ai`, `claude-*`, `us.anthropic.*`, `[1m]`); the user asks about an LLM (pricing/model choice/limits/caching) — never answer from memory; OR the task is LLM-shaped with provider unstated (agent/MCP/tool-definition/multi-agent/RAG/LLM-judge/computer-use; generate/summarize/extract/classify/rewrite/converse over NL; debugging refusals/cutoffs/streaming/tool-calls/tokens).\nSKIP only when another provider is being worked on (overrides all triggers): OpenAI/GPT/Gemini/Llama/Mistral/Cohere/Ollama named in the query; OR `grep -rE 'openai|langchain_openai|google.generativeai|genai|mistralai|cohere|ollama'` over the project hits (run this grep FIRST if no provider named — don't Read the file).\n- run: Launch and drive this project's app to see a change working. Use when asked to run, start, or screenshot the app, or to confirm a change works in the real app (not just tests). First looks for a project skill that already covers launching the app; otherwise falls back to built-in patterns per project type (CLI, server, TUI, Electron, browser-driven, library).\n- init: Initialize a new CLAUDE.md file with codebase documentation\n- review: Review a pull request\n- security-review: Complete a security review of the pending changes on the current branch","skillCount":166,"isInitial":true,"names":["autoplan","benchmark","browse","canary","careful","caveman","ccs-delegation","checkpoint","codex","connect-chrome","cso","design-consultation","design-html","design-review","design-shotgun","devex-review","diagnose","document-release","find-skills","freeze","grill-me","grill-with-docs","gsd-add-tests","gsd-ai-integration-phase","gsd-audit-fix","gsd-audit-milestone","gsd-audit-uat","gsd-autonomous","gsd-capture","gsd-cleanup","gsd-code-review","gsd-complete-milestone","gsd-config","gsd-debug","gsd-discuss-phase","gsd-docs-update","gsd-eval-review","gsd-execute-phase","gsd-explore","gsd-extract-learnings","gsd-fast","gsd-forensics","gsd-graphify","gsd-health","gsd-help","gsd-import","gsd-inbox","gsd-ingest-docs","gsd-manager","gsd-map-codebase","gsd-milestone-summary","gsd-mvp-phase","gsd-new-milestone","gsd-new-project","gsd-ns-context","gsd-ns-ideate","gsd-ns-manage","gsd-ns-project","gsd-ns-review","gsd-ns-workflow","gsd-pause-work","gsd-phase","gsd-plan-phase","gsd-plan-review-convergence","gsd-pr-branch","gsd-profile-user","gsd-progress","gsd-quick","gsd-resume-work","gsd-review","gsd-review-backlog","gsd-secure-phase","gsd-settings","gsd-ship","gsd-sketch","gsd-spec-phase","gsd-spike","gsd-stats","gsd-surface","gsd-thread","gsd-ui-phase","gsd-ui-review","gsd-ultraplan-phase","gsd-undo","gsd-update","gsd-validate-phase","gsd-verify-work","gsd-workspace","gsd-workstreams","gstack","gstack-upgrade","guard","handoff","health","improve-codebase-architecture","investigate","land-and-deploy","learn","mux-send","office-hours","open-gstack-browser","pair-agent","plan-ceo-review","plan-design-review","plan-devex-review","plan-eng-review","propose-issue","qa","qa-only","retro","review","screenshot-capture","setup-browser-cookies","setup-deploy","ship","to-prd","trace","traceable-reqs","unfreeze","win-marketplace-add","write-a-skill","ccs","ccs:continue","deep-research","frontend-design:frontend-design","spt:clear-psyche","spt:commune","spt:force-stop","spt:list-agents","spt:live","spt:new-alarm","spt:psyche-sync-setup","spt:ready","spt:revive","spt:send","spt:signoff","spt:whoami","caveman:caveman","caveman:caveman-commit","caveman:caveman-help","caveman:caveman-review","caveman:compress","everything:search","sptc:commune","sptc:force-stop","sptc:list-agents","sptc:live","sptc:ready","sptc:send","sptc:setup","sptc:signoff","sptc:subnet","sptc:version","update-config","keybindings-help","verify","code-review","simplify","fewer-permission-prompts","loop","schedule","claude-api","run","init","review","security-review"]},"type":"attachment","uuid":"1ee8c983-4868-404d-851a-d2a276007a46","timestamp":"2026-06-20T10:31:33.921Z","userType":"external","entrypoint":"cli","cwd":"C:\\Users\\decid\\Documents\\projects\\spt-core","sessionId":"ba9196fa-7544-41c6-854e-b36cebc3b771","version":"2.1.183","gitBranch":"v0.13.0-p1b-ack-deadlock"}

Cleared for operator HITL: large ctrl+V = no wedge (rides WT-native paste as keystrokes), right-click = bracketed paste, scroll works, broker stays serviceable under flood.
Co-authored by: doyle\n scroll → Shift+scroll is the accepted interim ("good enough for now"). The SGR scroll-forward (7.20) is moot for CC: CC enables NO mouse tracking (no internal scroll), so our capture-stolen wheel has nothing to forward TO. Operator confirmed Shift+scroll works under WT.
Follow-up the operator requested (post-v0.13.0): an AD\nAPTER-MANIFEST-enabled rc VT/mouse mode — declared (harness consumes mouse reports) ⇒ keep EnableMouseCapture + the SGR scroll-forward; default (CC) ⇒ SKIP capture so WT native wheel-scroll works, trading client-originated right-click paste (ctrl+V + Shift+scroll cover it). Resolves the capture-vs-native-scroll xor per-harness. Logged in\n DEFERRED.md @fa9d047 (pushed to origin/v0.13.0-p1b-ack-deadlock); mint a REQ-RC-VT-MODE-class req first when that milestone starts.
Cleanup: deleted the v0.13.0-p1-ctrlv-diag throwaway (local + origin) — its capture (11 frames / ack START=11 END=10) is already distilled into KH 7.19.
All v0.13.0 delivery-control work closed + \naccepted. Thanks for the build — clear on my side.

ROOT: spt-core has no `[session.resume]` template — cmd_endpoint_run re-passes session_id through `[session.self]` on resume, so CC reruns its FRESH command instead of native resume (`claude -r ..`) -> blank. CONTEXT L127-129 specs this seam; the manifest already has psyche_init->psyche_resume — MIR\n9\tROR IT for the agent's own session.
BUILD: (A) add `resume: Option<SessionRole>` to Session (manifest.rs + roles()/is_empty()); cmd_endpoint_run selects `[session.resume]` when --resume set AND declared, else FALL BACK to `[session.self]` (back-compat). (B) per-row ledger cwd (operator ruling): {ts,session_id,trigger,cwd} additive\n10\t serde-default; resume cwd = row cwd -> info.cwd -> current_dir; picker threads the selected row cwd through Outcome::Run.

Folds into P2 (same picker surface). @52cd081, see V0.13.0-P2-SESSION-RESUME-DESIGN.md §D.
CHANGE ResumeRow::title() (picker/model.rs:150-162): - OLD: `{head} @ {ts} (…{id5})` (raw RFC3339-UTC) - NEW: `\n13\t{head} - {local_time} (…{id5})` — separator ` @ ` -> ` - ` - {local_time} = `HH:MM<AM|PM> <TZ> MM-DD-YYYY` in LOCAL machine tz. e.g. `myproject - 03:45PM PST 06-19-2026 (…7fb10)` - impl: chrono::DateTime::parse_from_rfc3339(&self.ts) -> .with_timezone(&chrono::Local) -> "%I:%M%p" + tz + "\n14\t;%m-%d-%Y" (chrono clock feature already on in crates/spt/Cargo.toml). - TZ CAVEAT: chrono %Z on Windows may emit a LONG name ("Pacific Standard Time") not "PST". Prefer short abbrev; fallback = numeric offset (%z -> -0800). Surface at HITL for operator confirm. - Parse-fail fallback: keep raw ts (best-effort,\n15\t NEVER panic). - Rides REQ-RUN-PICKER (not a new REQ): update the existing title unit (view.rs:581-599) to the NEW shape, keep [unit->REQ-RUN-PICKER].\n16\tDISPATCH — v0.13.0 P1 (rc paste, ship-blocker). DEPENDS ON P0 (do P0 first; a paste chunk must not wedge). DESIGN (pull): V0.13.0-P1-RC-PASTE-DESIGN.md @796e82e. REQ-RC-WIN-PASTE SEEDED — activate [doc,impl,unit] (NO int — live clipboard+console mouse = HITL).
ROOT: RawGuard only enable_raw_mode; Windows co\n17\tnsole paste = synthetic per-char key events; ctrl+V -> ^V to CC which has NO local clipboard remotely -> remote paste is CLIENT-ORIGINATED.
FIX (cfg(windows), folds into your bug-2 event path): on a paste gesture, rc reads the LOCAL clipboard + forwards a BRACKETED PASTE (ESC[200~ + content + ESC[201~); CC (bracketed-paste mode on\n18\t) treats it as a paste — content intact, no submit-storm, agnostic. - ctrl+V: intercept Char('v')+CONTROL in the event loop -> read_clipboard -> bracketed paste. - right-click: RawGuard also EnableMouseCapture (disables console QuickEdit + ENABLE_MOUSE_INPUT so right-click surfaces as Event::Mouse on legacy cmd/powershell) -> \n19\tright-button -> read_clipboard -> bracketed paste; DROP all other mouse (operator confirms CC has NO mouse features, so capture costs nothing). Restore (DisableMouseCapture) on RawGuard drop. - read_clipboard = clipboard-win crate (cfg(windows)); empty/fail = clean no-op. Content forwarded VERBATIM (no translation). Unix UNCHANGED.\n20\t> Gates: bracketed framing exact (unit) + gesture->paste decision (other mouse dropped) + clipboard-win dep clean clippy + Cargo.lock + traceable/docs-drift. Surface when green.\n21\tP2 GATE-PASS @153c9c9 (REQ-SESSION-RESUME-TEMPLATE). Independently re-verified: clippy=0, docs-drift OK, all units (manifest/harnesshost selection+fallback/ledger cwd roundtrip+pre-migration+none-omit/picker), int resume_template_e2e NON-VACUOUS both arms (fresh->self, --resume->resume in recorded cwd), traceable \n22\t[doc,impl,unit,int] + REQ-RUN-PICKER covered, docs perri-buildable. Clean back-compat. Excellent work.
PROCEED TO P0 (REQ-HAZARD-PTY-INPUT-WRITER-WEDGE) — the active ship-blocker, no changes needed here.
Two notes (NON-blocking): 1. TZ form: your %z offset (-0800) is the design-D acceptable fallback — fine to LEAVE AS-IS p\n23\tending operator HITL confirm (operator may want a short abbrev; I'm asking them now). Don't rework unless I relay otherwise. 2. test-threads=1 for spt-daemon e2e — logged, pre-existing convention, fine.
Surface P0 green for gate. Reachable.\n24\tP0 GATE-PASS @0675b37 (REQ-HAZARD-PTY-INPUT-WRITER-WEDGE). The hard ship-blocker — independently re-verified: - clippy=0; write_input is SOLE-CALLER (input_writer thread only), every dispatch site (dispatch_input both paths / dispatch_endpoint_input / run_inject_worker / flush_inject_floor) enqueues; apply_once Pty\n25\tWrite = non-blocking enqueue (exactly-once preserved) - broker units 8/8 (FIFO order, DROP/HEAL injected-channel, exactly-once enqueue+dedup) - repro int NON-VACUOUS GREEN: pumped=7230 keystroke_accepted=true concurrent_attach_subscribed=true attach_received_output=true backpressured=true (pre-fix parks dispatch -> subscribed=false). \n26\tThe exact gate W1b lacked. - traceable [impl,unit,int] + W1b covered; docs-drift OK; KNOWN-HAZARDS 7.17 + CONTEXT note. Excellent — this was the big one.
PROCEED TO P1 (REQ-RC-WIN-PASTE) — the LAST build item. ctrl+V + right-click client-clipboard -> bracketed paste (P0 now carries the chunk safely). Surface green for gate.\n27\t
w5_a2_abandoned flaky-neighbor: noted, NOT yours, recorded for the P3/CI triage (same attach-area class as the CI Linux reds). I'll handle it in the CI pass — don't let it block P1.\n28\tP1 GATE-PASS @f7cf380 (REQ-RC-WIN-PASTE). The LAST build item — independently verified: clippy=0, rc units 12/12 (incl bracketed framing exact+verbatim / ctrl+V detection / mouse-paste-only-right-down / injected-reader no-op), traceable [doc,impl,unit], docs-drift OK, arm order correct (ctrl+V !armed guard preserves c\n29\ttrl-b precedence), clipboard-win cfg(windows). Pushed to origin (CI re-running on full round-2).
NEXT (mine): batched PATH re-deploy from f7cf380 -> operator HITL all four -> CI g\n30\treen (incl P3/w5_a2 triage) -> deployah v0.13.0. You're CLEAR on build. I may ping for P3/w5_a2_abandoned triage (the flaky-neighbor) if CI needs it. Excellent round — all four roots closed clean.\n31\tURGENT DIAGNOSIS (v0.13.0 HITL re-open) — P1 ctrl+V WEDGES THE ENTIRE BROKER. Right-click paste (P1b) works perfectly (short+long multiline). ctrl+V is broken. NOT a fix yet — I need a CONFIRM-FIRST instrumented + isolation build to pin the root. Don't guess-fix.
HARD EVIDENCE (operator HITL, Windows Terminal\n32\t): - A 1-CHARACTER clipboard ctrl+V ALSO wedges → NOT a flood/volume (rules out dispatch-saturation by frame count). - Wedge is PERMANENT + ENTIRE BROKER (can't attach new/existing), not one session. - Session STAYS CONTROLLED — closing the rc tab did NOT register the detach (the controller's broker conn-handler is blocked). - \n33\tRight-click (same clipboard_paste->wrap->send path) does NOT wedge. So post-gesture our bytes are fine; the difference is the GESTURE SOURCE.
PARADOX to resolve: read_clipboard runs on the stdin EVENT thread (separate from the output pump), so a blocked clipboard read shouldn't stall output drain → shouldn't wedge the broker. Ye\n34\tt it does. So either (a) WT's OWN ctrl+V paste accelerator injects something additional that hits the broker, or (b) our handler interacts with the broker controller-write path, or (c) something re-enters become_controller / the synchronous inline controller-write (attach.rs:120-134 known sync-write weakness) and blocks the per-conn handler.\n35\tr> BUILD ME A DIAGNOSTIC build (one deploy, multiple probes): 1. ISOLATION: gate our ctrl+V interception behind env SPT_RC_CTRLV (default on; SPT_RC_CTRLV=0 disables the is_ctrl_v arm, leaving WT to handle ctrl+V natively). Lets the operator test: does ctrl+V STILL wedge with OUR handler OFF? (yes => not our handler; no => our hand\n36\tler is the cause). 2. INSTRUMENT (env SPT_RC_DEBUG_PASTE): rc-side eprintln on — "CTRLV arm fired", "read_clipboard START", "read_clipboard END len=N" (a missing END line = read_clipboard blocks), "sent N bytes"; same for the right-mouse path for comparison. 3. INSTRUMENT broker-side (env SPT_BRO\n37\tKER_DEBUG_INPUT): log in dispatch_input ("INPUT recv N op=.. enqueue-done") AND the controller output-write / become_controller path ("CTRL_WRITE start/end", "become_controller replay start/end") so we see WHICH broker call blocks + whether the per-conn handler returns.
Deliver as a throwaway diagnostic bra\n38\tnch/commit (NOT the gate). Operator runs daemon+rc with the envs, presses 1-char ctrl+V, captures broker stderr + rc stderr. Surface the build + I'll relay capture instructions. This is the v0.13.0 ship-blocker — top priority. Reachable.\n39\tProbe LGTM — run-A/run-B isolation + START/END counts will pin it cleanly. PUSH the diag branch v0.13.0-p1-ctrlv-diag @b39e8a0 to origin so I can build+deploy it from a known commit in the spt-core-opbuild worktree (keeps it off your shared main tree). Confirm pushed + I'll deploy it to the operator's install path (af\n40\tter reaping the wedged spt-core daemons) and relay the capture run. Standing by to deploy the moment it's on origin.\n41\tCAPTURE RESULT + PROBE GAP. Operator pressed ctrl+V (single-char non-wedge THEN long-string wedge) in BOTH run A (handler ON) and run B (handler OFF). RESULT: - BOTH runs WEDGED on the long ctrl+V. => isolation says OUR ctrl+V handler is INNOCENT (off still wedges); WT's NATIVE ctrl+V paste is the trigger. - rc\n42\t-A logged ONLY "RMOUSE arm fired" (a right-click), NEVER "CTRLV arm fired" — despite the operator pressing ctrl+V. => our is_ctrl_v arm NEVER FIRED. Most likely WT CONSUMES Ctrl+V (paste accelerator) so the key event never reaches our Event::Key arm; WT instead injects the clipboard as input.
PROBE WAS INSUFFICI\n43\tENT (only logs on is_ctrl_v match, so "invisible ctrl+V" is ambiguous). ENHANCE — log EVERY event in spawn_stdin_reader_events, gated by SPT_RC_DEBUG_PASTE: - EVERY Event: Key (code + modifiers + kind), Mouse (kind + button), Paste (len), Resize. So we SEE exactly what WT delivers when the operator hits ctrl+V on a ~15-char clip\n44\tboard: nothing? a Key('v')+CTRL? a burst of Key char events (WT inject)? an Event::Paste? - broker side: log the INPUT FRAME BURST — recv frames with a running count + a tight timestamp delta, so we see if WT's paste = N rapid key-event frames + WHERE the burst stalls (the existing ack/CTRL_WRITE START/END stays).
This capture will\n45\t show whether WT injects the long paste as a key-event FLOOD (N frames) and exactly which broker call stops returning. Rebuild the diag (same branch v0.13.0-p1-ctrlv-diag, bump it), I'll redeploy + re-capture. The "both wedge" already tells us the FIX is NOT our handler — it's handling WT's native paste injection / the broker's res\n46\tponse to it. Top priority.\n47\tROOT PINNED — broker-A capture (enhanced diag, ctrl+V ~15-char "Reaping +deploying" on WT):
THE WEDGE = INPUT-ACK IPC BACKPRESSURE DEADLOCK (NOT P0, NOT output): - 11 input frames recv. write_input START/END = 11/11 (PTY write FINE — P0 holds). - ack send START=11 / END=10. Frame #11: recv -&g\n48\tt; write_input START/END -> "ack send START" op=...895 -> NEVER "ack send END". Then DISPATCH:3:Failed("The pipe is being closed os 232") when the tab closed. - So the per-conn handler BLOCKS on send_frame(applied_envelope) — writing the applied-ack back over the brain<->broker IPC conn. The brain\n49\t isn't draining acks (busy pushing the keystroke flood on the SAME conn) -> mutual backpressure deadlock -> permanent broker wedge + controller-stuck (handler can't process the detach). Same class as v0.12.1 L0 (two-conn split). ~10 threshold = the IPC pipe buffer filling.
ALSO (two SEPARATE rc-side facts from rc-A): 1. our is_\n50\tctrl_v arm is DEAD: WT delivers Ctrl+V as `Key code=Char('v') mods=CONTROL kind=RELEASE` ONLY — no Press. Our arm guards `kind==Press` -> NEVER fires. Operator's "not wired right" = correct. 2. WT SWALLOWS ctrl+V and injects the clipboard as a CHAR-BY-CHAR KEY FLOOD (I see "Reaping +deploying" as individual Char Pre\n51\tss/Release). So we CANNOT intercept ctrl+V on WT (WT consumes it + injects regardless). Our ctrl+V handler is broken AND redundant.
FIX DIRECTION (your call to confirm + design): - PRIMARY (ship-blocker): kill the input-ack backpressure deadlock. Candidate: SKIP the applied-ack for EPHEMERAL PtyWrite (the rc pump is fire-and-forward,\n52\t mints op_id for dedup only, never gates on the ack; PtyWrite has no replay so the exactly-once ack is informational + unused). No ack send -> no per-conn-handler block -> no deadlock. Alt: non-blocking/separate-conn ack (two-conn split for the ack direction). This fixes ANY input flood, not just ctrl+V. - SECONDARY: REMOVE our ctrl+V\n53\t interception (broken Press-guard + redundant; WT handles ctrl+V natively). Keep right-click (works via mouse-capture). Once the broker no longer wedges on a flood, WT's native ctrl+V paste lands as keystrokes without wedging (multiline may submit-storm — acceptable / document; bracketed paste only achievable via right-click which we keep).<\n54\tbr> Confirm the ack-send-block reading + design the primary fix. This is THE v0.13.0 ship-blocker. Logs at C:/Users/decid/Documents/projects/{broker,rc}-A.log if you want them.\n55\tDESIGN APPROVED — conditional-ack is clean, targeted, and preserves the two load-bearing invariants (shellchan ack-wait + exactly-once op_id dedup). Build it. This is the real ship-blocker fix (cures ANY input-flood deadlock, not just ctrl+V).
GATE CRITERIA (mine): 1. REPRO-FIRST int (non-negotiable, the key\n56\tstone): a flood of N operator input frames through serve_attach on ONE conn where N > the IPC pipe buffer (~10+, make it deterministic e.g. 64) -> PRE-FIX deadlocks (ack-send-START-without-END / handler stops draining; assert a concurrent attach or the detach can't be serviced) -> POST-FIX drains all N + the session stays live + a con\n57\tcurrent attach still opens. Real broker+brain, NO mocks. This is the exact gate the wedge needed. 2. shellchan PATH UNCHANGED: a shellchan send_effect still acks (ack=true) and shellchan.rs:210 still receives BrokerEvent::Applied (its one-at-a-time drain). Add/keep a unit proving ack=true still emits the applied frame and ack=false does NOT\n58\t. 3. Exactly-once: a replayed/duplicate op_id on the no-ack path still dedups at apply_once (no double PTY write) — unit. 4. N-1 caveat: KNOWN-HAZARDS note that an OLD resident broker ignores ack=false (deadlock persists until a broker restart — KH 7.9 broker-resident-wire-change class). InputReq.ack serde-default=true so an old brok\n59\ter + new brain, and new broker + old brain, both stay safe. 5. SECONDARY (same branch): REMOVE the is_ctrl_v arm + its units (dead Press-guard + redundant — WT swallows ctrl+V Release-only and injects the clipboard as a key flood we can't intercept). KEEP right-click (mouse-capture path) + EnableMouseCapture. Revise REQ-RC-WIN-PASTE scope\n60\t to right-click-only + the KNOWN-HAZARDS entry (ctrl+V rides WT-native paste; the broker fix makes it non-wedging; bracketed fidelity = right-click only). Consider dropping Mouse::Moved early (267-event noise in the capture) — minor, your call. 6. REQ: mint REQ-HAZARD-INPUT-ACK-BACKPRESSURE (or similar) for the deadlock [impl,unit,int]; a\n61\tmend REQ-RC-WIN-PASTE. clippy/traceable/docs-drift.
Surface green for gate. Then re-deploy + operator HITL (ctrl+V large = no wedge; right-click = bracketed paste; both no broker wedge). Excellent root-cause work — this is a deeper bug than P1, well caught.\n62\tGATE-PASS — P1b-rework bundle @394fc5e.
Invariants verified at code: 1) exactly-once intact — the `if req.ack` gate touches ONLY the applied-f\n64\trame WRITE; enqueue/dedup already ran above it (confirmed in broker.rs + the journal-anchor exactly_once test) 2) N-1 safe — InputReq.ack serde default_true 3) shellchan untouched — still send_effect (ack=true) + its Applied-wait 4) non-vacuousness real — FIFO-order ack-gate, journal-anchor exactly-once, keystone flood_sent (RED\n65\t-carrier=forkpty/linux; Windows forced RED only at N~2000)
ONE gate-finding (doc-only) — I fixed inline + committed @21bfd9a (LOCAL, NOT pushed): keystone assert-(1) comment claimed the revert is "Empirically RED on Windows 11" UNQUALIFIED\n66\t, which contradicts your own module header + FLOOD_N note (N=64 benign pre-fix on Windows; deterministic RED-carrier at 64 = forkpty/linux; Windows RED only at N~2000). Corrected the comment to match. Comment-only, ZERO binary impact — operator HITL re-deploy can proceed off 394fc5e unchanged.
Push 21bfd9a onto origin/v0.13.0-p1b-ack-\n67\tdeadlock myself, or you fold it into your next push? Your call.
Cleared for operator HITL: large ctrl+V = no wedge (rides WT-native paste as keystrokes), right-click = bracketed paste, scroll works, broker stays serviceable under flood.

Operator HITL on the re-deployed 21bfd9a binary: - large ctrl+V → no wedge ✓ (rides WT-native paste as keystrokes) - right-click → bracketed paste ✓ (multi-line intact, no submit-storm) - broker serviceable under flood ✓ (no permanent wedge) -\n70\t scroll → Shift+scroll is the accepted interim ("good enough for now"). The SGR scroll-forward (7.20) is moot for CC: CC enables NO mouse tracking (no internal scroll), so our capture-stolen wheel has nothing to forward TO. Operator confirmed Shift+scroll works under WT.
Follow-up the operator requested (post-v0.13.0): an AD\n71\tAPTER-MANIFEST-enabled rc VT/mouse mode — declared (harness consumes mouse reports) ⇒ keep EnableMouseCapture + the SGR scroll-forward; default (CC) ⇒ SKIP capture so WT native wheel-scroll works, trading client-originated right-click paste (ctrl+V + Shift+scroll cover it). Resolves the capture-vs-native-scroll xor per-harness. Logged in\n72\t DEFERRED.md @fa9d047 (pushed to origin/v0.13.0-p1b-ack-deadlock); mint a REQ-RC-VT-MODE-class req first when that milestone starts.
Cleanup: deleted the v0.13.0-p1-ctrlv-diag throwaway (local + origin) — its capture (11 frames / ack START=11 END=10) is already distilled into KH 7.19.
All v0.13.0 delivery-control work closed + \n73\taccepted. Thanks for the build — clear on my side.

BUILD: (A) add `resume: Option<SessionRole>` to Session (manifest.rs + roles()/is_empty()); cmd_endpoint_run selects `[session.resume]` when --resume set AND declared, else FALL BACK to `[session.self]` (back-compat). (B) per-row ledger cwd (operator ruling): {ts,session_id,trigger,cwd} additive\n serde-default; resume cwd = row cwd -> info.cwd -> current_dir; picker threads the selected row cwd through Outcome::Run. (C) PUBLIC DOCS (MANIFEST + harness-contract) teach `[session.resume]` so perri builds the adapter side blind — load-bearing, don't skip.
int = dummy-harness whose resume command differs from self: --resume \nruns RESUME cmd in recorded cwd (marker assert), fresh runs self. Gates: clippy/traceable/docs-drift. Surface when green.\n[RESEND — prior send hit an API error] P2 ADDENDUM (operator) — picker resume-row title reformat. Folds into P2 (same picker surface). @52cd081, see V0.13.0-P2-SESSION-RESUME-DESIGN.md §D.
CHANGE ResumeRow::title() (picker/model.rs:150-162): - OLD: `{head} @ {ts} (…{id5})` (raw RFC3339-UTC) - NEW: `\n{head} - {local_time} (…{id5})` — separator ` @ ` -> ` - ` - {local_time} = `HH:MM<AM|PM> <TZ> MM-DD-YYYY` in LOCAL machine tz. e.g. `myproject - 03:45PM PST 06-19-2026 (…7fb10)` - impl: chrono::DateTime::parse_from_rfc3339(&self.ts) -> .with_timezone(&chrono::Local) -> "%I:%M%p" + tz + "\n;%m-%d-%Y" (chrono clock feature already on in crates/spt/Cargo.toml). - TZ CAVEAT: chrono %Z on Windows may emit a LONG name ("Pacific Standard Time") not "PST". Prefer short abbrev; fallback = numeric offset (%z -> -0800). Surface at HITL for operator confirm. - Parse-fail fallback: keep raw ts (best-effort,\n NEVER panic). - Rides REQ-RUN-PICKER (not a new REQ): update the existing title unit (view.rs:581-599) to the NEW shape, keep [unit->REQ-RUN-PICKER].\nDISPATCH — v0.13.0 P1 (rc paste, ship-blocker). DEPENDS ON P0 (do P0 first; a paste chunk must not wedge). DESIGN (pull): V0.13.0-P1-RC-PASTE-DESIGN.md @796e82e. REQ-RC-WIN-PASTE SEEDED — activate [doc,impl,unit] (NO int — live clipboard+console mouse = HITL).
ROOT: RawGuard only enable_raw_mode; Windows co\nnsole paste = synthetic per-char key events; ctrl+V -> ^V to CC which has NO local clipboard remotely -> remote paste is CLIENT-ORIGINATED.
FIX (cfg(windows), folds into your bug-2 event path): on a paste gesture, rc reads the LOCAL clipboard + forwards a BRACKETED PASTE (ESC[200~ + content + ESC[201~); CC (bracketed-paste mode on\n) treats it as a paste — content intact, no submit-storm, agnostic. - ctrl+V: intercept Char('v')+CONTROL in the event loop -> read_clipboard -> bracketed paste. - right-click: RawGuard also EnableMouseCapture (disables console QuickEdit + ENABLE_MOUSE_INPUT so right-click surfaces as Event::Mouse on legacy cmd/powershell) -> \nright-button -> read_clipboard -> bracketed paste; DROP all other mouse (operator confirms CC has NO mouse features, so capture costs nothing). Restore (DisableMouseCapture) on RawGuard drop. - read_clipboard = clipboard-win crate (cfg(windows)); empty/fail = clean no-op. Content forwarded VERBATIM (no translation). Unix UNCHANGED.\n> Gates: bracketed framing exact (unit) + gesture->paste decision (other mouse dropped) + clipboard-win dep clean clippy + Cargo.lock + traceable/docs-drift. Surface when green.\nP2 GATE-PASS @153c9c9 (REQ-SESSION-RESUME-TEMPLATE). Independently re-verified: clippy=0, docs-drift OK, all units (manifest/harnesshost selection+fallback/ledger cwd roundtrip+pre-migration+none-omit/picker), int resume_template_e2e NON-VACUOUS both arms (fresh->self, --resume->resume in recorded cwd), traceable \n[doc,impl,unit,int] + REQ-RUN-PICKER covered, docs perri-buildable. Clean back-compat. Excellent work.
PROCEED TO P0 (REQ-HAZARD-PTY-INPUT-WRITER-WEDGE) — the active ship-blocker, no changes needed here.
Two notes (NON-blocking): 1. TZ form: your %z offset (-0800) is the design-D acceptable fallback — fine to LEAVE AS-IS p\nending operator HITL confirm (operator may want a short abbrev; I'm asking them now). Don't rework unless I relay otherwise. 2. test-threads=1 for spt-daemon e2e — logged, pre-existing convention, fine.
Surface P0 green for gate. Reachable.\nP0 GATE-PASS @0675b37 (REQ-HAZARD-PTY-INPUT-WRITER-WEDGE). The hard ship-blocker — independently re-verified: - clippy=0; write_input is SOLE-CALLER (input_writer thread only), every dispatch site (dispatch_input both paths / dispatch_endpoint_input / run_inject_worker / flush_inject_floor) enqueues; apply_once Pty\nWrite = non-blocking enqueue (exactly-once preserved) - broker units 8/8 (FIFO order, DROP/HEAL injected-channel, exactly-once enqueue+dedup) - repro int NON-VACUOUS GREEN: pumped=7230 keystroke_accepted=true concurrent_attach_subscribed=true attach_received_output=true backpressured=true (pre-fix parks dispatch -> subscribed=false). \nThe exact gate W1b lacked. - traceable [impl,unit,int] + W1b covered; docs-drift OK; KNOWN-HAZARDS 7.17 + CONTEXT note. Excellent — this was the big one.
PROCEED TO P1 (REQ-RC-WIN-PASTE) — the LAST build item. ctrl+V + right-click client-clipboard -> bracketed paste (P0 now carries the chunk safely). Surface green for gate.\n
w5_a2_abandoned flaky-neighbor: noted, NOT yours, recorded for the P3/CI triage (same attach-area class as the CI Linux reds). I'll handle it in the CI pass — don't let it block P1.\nP1 GATE-PASS @f7cf380 (REQ-RC-WIN-PASTE). The LAST build item — independently verified: clippy=0, rc units 12/12 (incl bracketed framing exact+verbatim / ctrl+V detection / mouse-paste-only-right-down / injected-reader no-op), traceable [doc,impl,unit], docs-drift OK, arm order correct (ctrl+V !armed guard preserves c\ntrl-b precedence), clipboard-win cfg(windows). Pushed to origin (CI re-running on full round-2).
NEXT (mine): batched PATH re-deploy from f7cf380 -> operator HITL all four -> CI g\nreen (incl P3/w5_a2 triage) -> deployah v0.13.0. You're CLEAR on build. I may ping for P3/w5_a2_abandoned triage (the flaky-neighbor) if CI needs it. Excellent round — all four roots closed clean.\nURGENT DIAGNOSIS (v0.13.0 HITL re-open) — P1 ctrl+V WEDGES THE ENTIRE BROKER. Right-click paste (P1b) works perfectly (short+long multiline). ctrl+V is broken. NOT a fix yet — I need a CONFIRM-FIRST instrumented + isolation build to pin the root. Don't guess-fix.
HARD EVIDENCE (operator HITL, Windows Terminal\n): - A 1-CHARACTER clipboard ctrl+V ALSO wedges → NOT a flood/volume (rules out dispatch-saturation by frame count). - Wedge is PERMANENT + ENTIRE BROKER (can't attach new/existing), not one session. - Session STAYS CONTROLLED — closing the rc tab did NOT register the detach (the controller's broker conn-handler is blocked). - \nRight-click (same clipboard_paste->wrap->send path) does NOT wedge. So post-gesture our bytes are fine; the difference is the GESTURE SOURCE.
PARADOX to resolve: read_clipboard runs on the stdin EVENT thread (separate from the output pump), so a blocked clipboard read shouldn't stall output drain → shouldn't wedge the broker. Ye\nt it does. So either (a) WT's OWN ctrl+V paste accelerator injects something additional that hits the broker, or (b) our handler interacts with the broker controller-write path, or (c) something re-enters become_controller / the synchronous inline controller-write (attach.rs:120-134 known sync-write weakness) and blocks the per-conn handler.\nr> BUILD ME A DIAGNOSTIC build (one deploy, multiple probes): 1. ISOLATION: gate our ctrl+V interception behind env SPT_RC_CTRLV (default on; SPT_RC_CTRLV=0 disables the is_ctrl_v arm, leaving WT to handle ctrl+V natively). Lets the operator test: does ctrl+V STILL wedge with OUR handler OFF? (yes => not our handler; no => our hand\nler is the cause). 2. INSTRUMENT (env SPT_RC_DEBUG_PASTE): rc-side eprintln on — "CTRLV arm fired", "read_clipboard START", "read_clipboard END len=N" (a missing END line = read_clipboard blocks), "sent N bytes"; same for the right-mouse path for comparison. 3. INSTRUMENT broker-side (env SPT_BRO\nKER_DEBUG_INPUT): log in dispatch_input ("INPUT recv N op=.. enqueue-done") AND the controller output-write / become_controller path ("CTRL_WRITE start/end", "become_controller replay start/end") so we see WHICH broker call blocks + whether the per-conn handler returns.
Deliver as a throwaway diagnostic bra\nnch/commit (NOT the gate). Operator runs daemon+rc with the envs, presses 1-char ctrl+V, captures broker stderr + rc stderr. Surface the build + I'll relay capture instructions. This is the v0.13.0 ship-blocker — top priority. Reachable.\nProbe LGTM — run-A/run-B isolation + START/END counts will pin it cleanly. PUSH the diag branch v0.13.0-p1-ctrlv-diag @b39e8a0 to origin so I can build+deploy it from a known commit in the spt-core-opbuild worktree (keeps it off your shared main tree). Confirm pushed + I'll deploy it to the operator's install path (af\nter reaping the wedged spt-core daemons) and relay the capture run. Standing by to deploy the moment it's on origin.\nCAPTURE RESULT + PROBE GAP. Operator pressed ctrl+V (single-char non-wedge THEN long-string wedge) in BOTH run A (handler ON) and run B (handler OFF). RESULT: - BOTH runs WEDGED on the long ctrl+V. => isolation says OUR ctrl+V handler is INNOCENT (off still wedges); WT's NATIVE ctrl+V paste is the trigger. - rc\n-A logged ONLY "RMOUSE arm fired" (a right-click), NEVER "CTRLV arm fired" — despite the operator pressing ctrl+V. => our is_ctrl_v arm NEVER FIRED. Most likely WT CONSUMES Ctrl+V (paste accelerator) so the key event never reaches our Event::Key arm; WT instead injects the clipboard as input.
PROBE WAS INSUFFICI\nENT (only logs on is_ctrl_v match, so "invisible ctrl+V" is ambiguous). ENHANCE — log EVERY event in spawn_stdin_reader_events, gated by SPT_RC_DEBUG_PASTE: - EVERY Event: Key (code + modifiers + kind), Mouse (kind + button), Paste (len), Resize. So we SEE exactly what WT delivers when the operator hits ctrl+V on a ~15-char clip\nboard: nothing? a Key('v')+CTRL? a burst of Key char events (WT inject)? an Event::Paste? - broker side: log the INPUT FRAME BURST — recv frames with a running count + a tight timestamp delta, so we see if WT's paste = N rapid key-event frames + WHERE the burst stalls (the existing ack/CTRL_WRITE START/END stays).
This capture will\n show whether WT injects the long paste as a key-event FLOOD (N frames) and exactly which broker call stops returning. Rebuild the diag (same branch v0.13.0-p1-ctrlv-diag, bump it), I'll redeploy + re-capture. The "both wedge" already tells us the FIX is NOT our handler — it's handling WT's native paste injection / the broker's res\nponse to it. Top priority.\nROOT PINNED — broker-A capture (enhanced diag, ctrl+V ~15-char "Reaping +deploying" on WT):
THE WEDGE = INPUT-ACK IPC BACKPRESSURE DEADLOCK (NOT P0, NOT output): - 11 input frames recv. write_input START/END = 11/11 (PTY write FINE — P0 holds). - ack send START=11 / END=10. Frame #11: recv -&g\nt; write_input START/END -> "ack send START" op=...895 -> NEVER "ack send END". Then DISPATCH:3:Failed("The pipe is being closed os 232") when the tab closed. - So the per-conn handler BLOCKS on send_frame(applied_envelope) — writing the applied-ack back over the brain<->broker IPC conn. The brain\n isn't draining acks (busy pushing the keystroke flood on the SAME conn) -> mutual backpressure deadlock -> permanent broker wedge + controller-stuck (handler can't process the detach). Same class as v0.12.1 L0 (two-conn split). ~10 threshold = the IPC pipe buffer filling.
ALSO (two SEPARATE rc-side facts from rc-A): 1. our is_\nctrl_v arm is DEAD: WT delivers Ctrl+V as `Key code=Char('v') mods=CONTROL kind=RELEASE` ONLY — no Press. Our arm guards `kind==Press` -> NEVER fires. Operator's "not wired right" = correct. 2. WT SWALLOWS ctrl+V and injects the clipboard as a CHAR-BY-CHAR KEY FLOOD (I see "Reaping +deploying" as individual Char Pre\nss/Release). So we CANNOT intercept ctrl+V on WT (WT consumes it + injects regardless). Our ctrl+V handler is broken AND redundant.
FIX DIRECTION (your call to confirm + design): - PRIMARY (ship-blocker): kill the input-ack backpressure deadlock. Candidate: SKIP the applied-ack for EPHEMERAL PtyWrite (the rc pump is fire-and-forward,\n mints op_id for dedup only, never gates on the ack; PtyWrite has no replay so the exactly-once ack is informational + unused). No ack send -> no per-conn-handler block -> no deadlock. Alt: non-blocking/separate-conn ack (two-conn split for the ack direction). This fixes ANY input flood, not just ctrl+V. - SECONDARY: REMOVE our ctrl+V\n interception (broken Press-guard + redundant; WT handles ctrl+V natively). Keep right-click (works via mouse-capture). Once the broker no longer wedges on a flood, WT's native ctrl+V paste lands as keystrokes without wedging (multiline may submit-storm — acceptable / document; bracketed paste only achievable via right-click which we keep).<\nbr> Confirm the ack-send-block reading + design the primary fix. This is THE v0.13.0 ship-blocker. Logs at C:/Users/decid/Documents/projects/{broker,rc}-A.log if you want them.\nDESIGN APPROVED — conditional-ack is clean, targeted, and preserves the two load-bearing invariants (shellchan ack-wait + exactly-once op_id dedup). Build it. This is the real ship-blocker fix (cures ANY input-flood deadlock, not just ctrl+V).
GATE CRITERIA (mine): 1. REPRO-FIRST int (non-negotiable, the key\nstone): a flood of N operator input frames through serve_attach on ONE conn where N > the IPC pipe buffer (~10+, make it deterministic e.g. 64) -> PRE-FIX deadlocks (ack-send-START-without-END / handler stops draining; assert a concurrent attach or the detach can't be serviced) -> POST-FIX drains all N + the session stays live + a con\ncurrent attach still opens. Real broker+brain, NO mocks. This is the exact gate the wedge needed. 2. shellchan PATH UNCHANGED: a shellchan send_effect still acks (ack=true) and shellchan.rs:210 still receives BrokerEvent::Applied (its one-at-a-time drain). Add/keep a unit proving ack=true still emits the applied frame and ack=false does NOT\n. 3. Exactly-once: a replayed/duplicate op_id on the no-ack path still dedups at apply_once (no double PTY write) — unit. 4. N-1 caveat: KNOWN-HAZARDS note that an OLD resident broker ignores ack=false (deadlock persists until a broker restart — KH 7.9 broker-resident-wire-change class). InputReq.ack serde-default=true so an old brok\ner + new brain, and new broker + old brain, both stay safe. 5. SECONDARY (same branch): REMOVE the is_ctrl_v arm + its units (dead Press-guard + redundant — WT swallows ctrl+V Release-only and injects the clipboard as a key flood we can't intercept). KEEP right-click (mouse-capture path) + EnableMouseCapture. Revise REQ-RC-WIN-PASTE scope\n to right-click-only + the KNOWN-HAZARDS entry (ctrl+V rides WT-native paste; the broker fix makes it non-wedging; bracketed fidelity = right-click only). Consider dropping Mouse::Moved early (267-event noise in the capture) — minor, your call. 6. REQ: mint REQ-HAZARD-INPUT-ACK-BACKPRESSURE (or similar) for the deadlock [impl,unit,int]; a\nmend REQ-RC-WIN-PASTE. clippy/traceable/docs-drift.
Surface green for gate. Then re-deploy + operator HITL (ctrl+V large = no wedge; right-click = bracketed paste; both no broker wedge). Excellent root-cause work — this is a deeper bug than P1, well caught.\nGATE-PASS — P1b-rework bundle @394fc5e.
Invariants verified at code: 1) exactly-once intact — the `if req.ack` gate touches ONLY the applied-f\nrame WRITE; enqueue/dedup already ran above it (confirmed in broker.rs + the journal-anchor exactly_once test) 2) N-1 safe — InputReq.ack serde default_true 3) shellchan untouched — still send_effect (ack=true) + its Applied-wait 4) non-vacuousness real — FIFO-order ack-gate, journal-anchor exactly-once, keystone flood_sent (RED\n-carrier=forkpty/linux; Windows forced RED only at N~2000)
ONE gate-finding (doc-only) — I fixed inline + committed @21bfd9a (LOCAL, NOT pushed): keystone assert-(1) comment claimed the revert is "Empirically RED on Windows 11" UNQUALIFIED\n, which contradicts your own module header + FLOOD_N note (N=64 benign pre-fix on Windows; deterministic RED-carrier at 64 = forkpty/linux; Windows RED only at N~2000). Corrected the comment to match. Comment-only, ZERO binary impact — operator HITL re-deploy can proceed off 394fc5e unchanged.
Push 21bfd9a onto origin/v0.13.0-p1b-ack-\ndeadlock myself, or you fold it into your next push? Your call.
Cleared for operator HITL: large ctrl+V = no wedge (rides WT-native paste as keystrokes), right-click = bracketed paste, scroll works, broker stays serviceable under flood.

ON RESUME, CHECK HITL OUTCOME FIRST: 1. HITL PASSED → ship-ready. Confirm with doyle: merge P1b onto delivery-control or main; version/changelog; perri adapter follow-on ([session.resume] `claude -r {session_id}` + idle-translation-binary). Diag branch v0.13.0-p1-ctrlv-diag deletable (doyle owns). 2.

HITL NOT YET RUN → stay reachable, no action.
NO open build tasks. w5_a2_abandoned = doyle P3/CI triage, NOT mine. Gate = doyle. </live-context> <project-context> (name=spt-core): </project-context>\nHITL VERDICT — v0.13.0 P1b shipped + accepted.
Operator HITL on the re-deployed 21bfd9a binary: - large ctrl+V → no wedge ✓ (rides WT-native paste as keystrokes) - right-click → bracketed paste ✓ (multi-line intact, no submit-storm) - broker serviceable under flood ✓ (no permanent wedge) -\n scroll → Shift+scroll is the accepted interim ("good enough for now"). The SGR scroll-forward (7.20) is moot for CC: CC enables NO mouse tracking (no internal scroll), so our capture-stolen wheel has nothing to forward TO. Operator confirmed Shift+scroll works under WT.
Follow-up the operator requested (post-v0.13.0): an AD\nAPTER-MANIFEST-enabled rc VT/mouse mode — declared (harness consumes mouse reports) ⇒ keep EnableMouseCapture + the SGR scroll-forward; default (CC) ⇒ SKIP capture so WT native wheel-scroll works, trading client-originated right-click paste (ctrl+V + Shift+scroll cover it). Resolves the capture-vs-native-scroll xor per-harness. Logged in\n DEFERRED.md @fa9d047 (pushed to origin/v0.13.0-p1b-ack-deadlock); mint a REQ-RC-VT-MODE-class req first when that milestone starts.
Cleanup: deleted the v0.13.0-p1-ctrlv-diag throwaway (local + origin) — its capture (11 frames / ack START=11 END=10) is already distilled into KH 7.19.
All v0.13.0 delivery-control work closed + \naccepted. Thanks for the build — clear on my side.

ROOT (doyle, instrumented RACEDIAG repro on kitsubito): on a brain-restart re-serve the handoff brain registers as controller on the SAME session TWICE over the SAME `Brain::conn` socket — (1) `Brain::handoff` eagerly `subscribe(prior.session_id, prior.next_seq=1)` → `become_controller(from_seq=1)`, initial=[1], spawns writer-A (writes seq 1); (2) `serve_attach` re-handles the replayed `Request{from_seq:0}` → `attach_as(sid,0)` → `become_controller(from_seq=0)`, initial=[0,1], spawns writer-B (writes 0 then 1). `become_controller` (broker.rs) drops the prior `ControllerSink` (its `tx`) but does NOT stop the prior writer thread — writer-A keeps flushing its owned `initial` batch, and both writers hold clones of the same `SharedSend` (`Arc>`) with NO inter-thread ordering. When writer-A's seq 1 wins the socket before writer-B's seq 0, the strict legacy consumer (brain.rs read_event reject-gap path) sees `output gap: got seq 1 want 0` → the test `attach_survives_target_brain_restart_exactly_once` panics at `.expect(\\\"re-serve\\\")` OR HANGS in `render_until` (serve thread died on the gap → MARKER_TWO never reaches the wire). `prior.next_seq` is life1's CONSUMPTION cursor, NOT life2's connection state — life2's socket has been sent NOTHING, so a `from_seq=0` full replay on a connection that already streamed seq 1 is contradictory. Snap-above tolerance ALONE can't fix it (it would dedup-drop the late seq 0 → byte loss → the exactly-once byte-identity assert fails). PRE-EXISTING, surfaced by the v0.13.0 green-both-runners release gate; P1b is INNOCENT (its diff touches only input-ack machinery, proven mechanically + the test passes post-P1b in isolation). Sibling flaky cluster: `inject_control_wedge::g2`, `broker::spawn_env_reaches_child`. INVARIANT: on a single brain↔broker connection the controller output-frame stream is monotonic non-decreasing in seq (modulo dedup re-sends); exactly ONE `controller_writer` is ever live per connection; a SUPERSEDED writer writes NO further frames; a re-serve never replays a seq below what the connection already received. FIX (doyle design, V0.13.0-P1C-CONTROLLER-WRITER-REORDER-PLAN.md, three parts): (1) PRIMARY — `Brain::handoff` no longer eagerly `subscribe`s-as-controller; `serve_attach`'s `attach_as(sid,0)` is the SOLE controller registration + replay for that connection (handoff is test-only per the brain.rs comment; no production caller depends on the eager subscribe — production resumes via `cold_start`+`resume_sessions`). (2) BROKER HARDENING — `controller_writer` is epoch-gated: `controller_epoch` becomes a shared `Arc`, the writer snapshots its own epoch and checks the shared one before each frame (initial-batch AND live loop), returning the moment it is superseded — so a double-registration can never silently keep a superseded writer flushing (W1-safe: never blocks the drain under `Mutex`). (3) DEFENSE-IN-DEPTH — `Brain::handoff` seeds `session_cursors` at `prior.next_seq` so the consumer uses the production dedup-below+snap-above path (matching `resume_sessions`), not the strict reject-gap legacy trap.

Brain not reading → the broker→brain return direction fills (~10 frames = the IPC pipe buffer) → `send_frame` BLOCKS → the handler stops reading → the brain's writes block → mutual full-duplex DEADLOCK. (Capture: 11 frames, `write_input` 11/11 — P0 holds; `ack send` START=11/END=10 — frame #11's ack never returns.) WT's ctrl+V paste-accelerator key-flood was the trigger; the deadlock is generic to ANY input flood.\n457\t- **Invariant:** the applied-ack is OPT-IN. `InputReq` carries `ack: bool` (serde `default = true`, N-1-safe). The fire-and-forward operator/rc path (`serve_attach`) sends `ack=false` via `Brain::send_effect_no_ack`; `dispatch_input` writes NO applied frame when `ack=false`, so the per-conn handler never writes back while servicing the flood → it always drains → no deadlock (cures ANY input flood). `shellchan` (one-at-a-time spool delivery, WAITS on `BrokerEvent::Applied`) keeps `send_effect` (`ack=true`). EXACTLY-ONCE preserved: the broker dedups by `(session, op_id)` at the applied-set regardless of the ack. **N-1 caveat:** an OLD resident broker (the self-update window) ignores `ack=false` → still acks → the deadlock persists until a broker restart (inherent broker-resident-wire-change class, see 7.9).\n458\t- **spt-core mapping:** impl `msg.rs` `InputReq.ack` (`default_true`) + `brain.rs` `send_effect_no_ack`/`send_effect_inner` + `attach.rs` `serve_attach` operator path → `send_effect_no_ack` + `broker.rs` `dispatch_input` gates `send_frame(applied)` on `req.ack`; unit the serde default + the ack-emitted-iff-true + the no-ack-path exactly-once dedup; int (keystone, repro-first) a flood of N>pipe-buffer input frames through `serve_attach` on one conn — PRE-FIX deadlocks, POST-FIX drains all N + the session stays live + a concurrent attach opens (real broker+brain, no mocks).\n459\t- **Source:** v0.13.0 P1b (operator HITL re-open; doyle /diagnose on the enhanced rc+broker capture 2026-06-19).

The mouse handler: right-button-DOWN → bracketed clipboard paste (7.18, unchanged); `ScrollUp/Down` → an xterm SGR mouse report (`ESC[<64;col+1;row+1M` up / `ESC[<65;…M` down; 0-based crossterm → 1-based xterm), forwarded ONLY when `enabled && sgr` (else DROP — a legacy report the harness may misread is garbage); Moved/drag/left/middle DROP (scroll is the need; click-forward risks garbage, no click-to-position).

Brain not reading → the broker→brain return direction fills (~10 frames = the IPC pipe buffer) → `send_frame` BLOCKS → the handler stops reading → the brain's writes block → mutual full-duplex DEADLOCK. (Capture: 11 frames, `write_input` 11/11 — P0 holds; `ack send` START=11/END=10 — frame #11's ack never returns.) WT's ctrl+V paste-accelerator key-flood was the trigger; the deadlock is generic to ANY input flood.\n- **Invariant:** the applied-ack is OPT-IN. `InputReq` carries `ack: bool` (serde `default = true`, N-1-safe). The fire-and-forward operator/rc path (`serve_attach`) sends `ack=false` via `Brain::send_effect_no_ack`; `dispatch_input` writes NO applied frame when `ack=false`, so the per-conn handler never writes back while servicing the flood → it always drains → no deadlock (cures ANY input flood). `shellchan` (one-at-a-time spool delivery, WAITS on `BrokerEvent::Applied`) keeps `send_effect` (`ack=true`). EXACTLY-ONCE preserved: the broker dedups by `(session, op_id)` at the applied-set regardless of the ack. **N-1 caveat:** an OLD resident broker (the self-update window) ignores `ack=false` → still acks → the deadlock persists until a broker restart (inherent broker-resident-wire-change class, see 7.9).\n- **spt-core mapping:** impl `msg.rs` `InputReq.ack` (`default_true`) + `brain.rs` `send_effect_no_ack`/`send_effect_inner` + `attach.rs` `serve_attach` operator path → `send_effect_no_ack` + `broker.rs` `dispatch_input` gates `send_frame(applied)` on `req.ack`; unit the serde default + the ack-emitted-iff-true + the no-ack-path exactly-once dedup; int (keystone, repro-first) a flood of N>pipe-buffer input frames through `serve_attach` on one conn — PRE-FIX deadlocks, POST-FIX drains all N + the session stays live + a concurrent attach opens (real broker+brain, no mocks).\n- **Source:** v0.13.0 P1b (operator HITL re-open; doyle /diagnose on the enhanced rc+broker capture 2026-06-19).

Rationale: `spt whoami` is a thin alias of `endpoint list` — a just-online agent running `whoami` must see its OWN perch, or it gets an omitted-self view ('chaos'). FIX: drop the `--local` flag + its `--detail` conflict test + the v0.10.0 REQ-PICKER-5 hint line (cli.rs:1678) + cmd_list_local; the bare list merges local perches into the subnet view; fix the whoami alias path accordingly. Run `cargo run -p xtask -- gen` (docs-drift, DEFAULT target). (v0.12.1)\n [OK] REQ-ENDPOINT-PURGE required: [doc, impl, unit, int] stages: +doc +impl +unit +int\n--\n A legitimately dead PTY child (real crash/kill) + an undrained operator pump must NOT wedge the broker for all other clients. ROOT (v0.12.0 real-harness defect): loopback attach output is a blocking write_all into a bounded 64KB tokio duplex (nethost.rs:1040,1090); when the operator's rc pump stops draining (tab closed) the buffer fills and write_all blocks forever (the 'loopback never hangs' assumption at nethost.rs:1103 is false), parking a worker in the 2-worker net runtime (nethost.rs:640); a couple of these saturate BOTH workers → every new attach / `endpoint run` stalls right after 'PUMP_IPC_READER: spawned' → 30s FIRST_EVENT_GRACE → 'no output / dead or wedged'; `daemon stop` cannot join the stuck workers. DISTINCT from the removed B1 path-(c) mutex deadlock. DISPOSITION = PROVE-DON'T-CHANGE (doyle GATE-PASS @e883f45, 2026-06-18): this ROOT is the SUPERSEDED v0.12.0 hypothesis — the post-L0 code ALREADY prevents the wedge, so NO fail-fast / worker-count code was added. serve_attach forwards fire-and-forget (net_stream_send op_id=None) and the broker-side send_stream is already BROKER-QUIC-DEADLINE-bounded (bounded_block_on, 10s); the loopback duplex is drained broker-INTERNALLY by the operator row's own read pump (RecvHalf::Loopback, retentive_cap==0 → evict-not-park) so a dead rc (a dropped IPC subscriber) never backs peer_w up; bounded_block_on parks the BROKER DISPATCH thread, not a net worker → no worker-pool exhaustion (full mechanism in the required_stages comment). Folds the status=online sub-check: a dead spt-hosted endpoint is marked OFFLINE within one reconcile tick on abrupt child death (broker exit-waiter reaps the session → B2 sees it absent) — PROVEN, no change. (v0.12.1)\n [OK] REQ-HAZARD-BIND-CWD-UNSET required: [impl, unit, int] stages: -doc +impl +unit +int\n A bound endpoint's `info.cwd` is SET at bind so a freshly-created perch appears under its own project tab. ROOT (found, v0.13.0): `info.cwd` is NEVER set on bind — `cmd_bind` (spt-hosted) and `bind_from_seed` (harness-hosted) never thread cwd into `establish_perch`/`rec.cwd`. FIX: `cmd_bind` reads its own `current_dir` (the broker spawned it in `project_cwd`); `bind_from_seed` passes `seed.cwd` (already captured at seed time, currently DISCARDED). DISTINCT from REQ-PICKER-HISTORY-FRESH (v0.12.1) — that unioned cwd-origin into picker MEMBERSHIP but tested merge_origin_project with a PROVIDED origin; it never asserted `info.cwd` is actually set on bind, so a real `endpoint run` perch still had an empty cwd and the union had nothing to union. This is the v0.12.1 P1 'appears under its own project right away' claim that was REFUTED in the changelog — delivered for real here. (v0.13.0)\n [OK] REQ-HAZARD-BRAIN-RESPAWN-PATH required: [doc, impl, unit, int] stages: +doc +impl +unit +int\n--\n The broker bounds every brain-waiting QUIC op (dial / open_stream / send_stream) so a black-holed or dead peer fails PROMPTLY with an ORDINARY error the broker REPLIES, never an unbounded await. The bound (< the brain's 30s PUMP_PEER_IO_TIMEOUT so the BROKER fires first) surfaces to the pump as a normal broker error reply → peer_outcome's non-TimedOut arm → drop conn + redial next tick, the round CONTINUES and the heartbeat keeps advancing — it must NEVER manifest as the brain's own read-deadline (the A-half poison → supervised-restart path REQ-HAZARD-PUMP-IPC-DEADLINE guards). Exactly-once is preserved: a timed-out journaled op fails INSIDE its apply_once closure so no phantom conn_id/stream_id is recorded and a fresh tick re-dials cleanly. The happy path is unchanged (a live peer completes with zero added latency; the bound only bites a non-responsive peer). This is the ROOT-cause cure for the 2.2h hfenduleam pump wedge — a dead roster peer whose QUIC path the broker awaited unbounded — recurring on hfenduleam 2026-06-16.\n [OK] REQ-HAZARD-BROKER-SEED-WIRE-SKEW required: [doc, impl, unit] stages: +doc +impl +unit -int\n A daemon-state wire-format change (e.g. the v0.9.0 adapter-agnostic Seed) does NOT take effect until a DELIBERATE full broker restart: the broker serves the seed-control channel and is RESIDENT across a brain-only self-update (ADR-0004 no-terminate-during-update forbids auto-killing it), so a NEW-version CLI talking to a still-resident OLD broker fails the seed handshake — the old broker cannot deserialize the new Seed (its formerly-required `adapter` field is gone) and drops the conn without an ack, which surfaces to the CLI as a raw UnexpectedEof 'failed to fill whole buffer'. spt-core must (a) surface an ACTIONABLE diagnostic on that seed-ack EOF (name the stale-broker cause + the `spt daemon stop` fix — the broker restarts on the next api call), never the cryptic io error; and (b) document the operational rule (a deliberate broker restart is required on any daemon-state wire change — NOT automatic) + the FORWARD discipline (daemon-state/Seed schema changes stay additive + serde-default so a resident OLD broker tolerates a NEW CLI across a brain-only update; note this would NOT have rescued 0.9.0 itself, since the old broker's `adapter` was a required field). perri PREP-4 FINDING 1 (v0.9.0 CLI vs stale 0.8.x broker).\n [OK] REQ-HAZARD-CASCADE-WIPE-GUARD required: [impl, unit] stages: -doc +impl +unit -int\n No hard-delete of a parent hosting non-empty children (6.3)\n [OK] REQ-HAZARD-CHILD-CONSOLE-FLASH required: [impl, unit] stages: +doc +impl +unit -int\n--\n [--] REQ-HAZARD-CONTROLLER-WRITER-REORDER required: [doc, impl, unit, int] stages: +doc +impl -unit -int\n Two `controller_writer` threads must never race ONE brain↔broker connection's socket. ROOT (doyle, instrumented RACEDIAG repro on kitsubito): on a brain-restart re-serve the handoff brain registers as controller on the SAME session TWICE over the SAME `Brain::conn` socket — (1) `Brain::handoff` eagerly `subscribe(prior.session_id, prior.next_seq=1)` → `become_controller(from_seq=1)`, initial=[1], spawns writer-A (writes seq 1); (2) `serve_attach` re-handles the replayed `Request{from_seq:0}` → `attach_as(sid,0)` → `become_controller(from_seq=0)`, initial=[0,1], spawns writer-B (writes 0 then 1). `become_controller` (broker.rs) drops the prior `ControllerSink` (its `tx`) but does NOT stop the prior writer thread — writer-A keeps flushing its owned `initial` batch, and both writers hold clones of the same `SharedSend` (`Arc>`) with NO inter-thread ordering. When writer-A's seq 1 wins the socket before writer-B's seq 0, the strict legacy consumer (brain.rs read_event reject-gap path) sees `output gap: got seq 1 want 0` → the test `attach_survives_target_brain_restart_exactly_once` panics at `.expect(\"re-serve\")` OR HANGS in `render_until` (serve thread died on the gap → MARKER_TWO never reaches the wire). `prior.next_seq` is life1's CONSUMPTION cursor, NOT life2's connection state — life2's socket has been sent NOTHING, so a `from_seq=0` full replay on a connection that already streamed seq 1 is contradictory. Snap-above tolerance ALONE can't fix it (it would dedup-drop the late seq 0 → byte loss → the exactly-once byte-identity assert fails). PRE-EXISTING, surfaced by the v0.13.0 green-both-runners release gate; P1b is INNOCENT (its diff touches only input-ack machinery, proven mechanically + the test passes post-P1b in isolation). Sibling flaky cluster: `inject_control_wedge::g2`, `broker::spawn_env_reaches_child`. INVARIANT: on a single brain↔broker connection the controller output-frame stream is monotonic non-decreasing in seq (modulo dedup re-sends); exactly ONE `controller_writer` is ever live per connection; a SUPERSEDED writer writes NO further frames; a re-serve never replays a seq below what the connection already received. FIX (doyle design, V0.13.0-P1C-CONTROLLER-WRITER-REORDER-PLAN.md, three parts): (1) PRIMARY — `Brain::handoff` no longer eagerly `subscribe`s-as-controller; `serve_attach`'s `attach_as(sid,0)` is the SOLE controller registration + replay for that connection (handoff is test-only per the brain.rs comment; no production caller depends on the eager subscribe — production resumes via `cold_start`+`resume_sessions`). (2) BROKER HARDENING — `controller_writer` is epoch-gated: `controller_epoch` becomes a shared `Arc`, the writer snapshots its own epoch and checks the shared one before each frame (initial-batch AND live loop), returning the moment it is superseded — so a double-registration can never silently keep a superseded writer flushing (W1-safe: never blocks the drain under `Mutex`). (3) DEFENSE-IN-DEPTH — `Brain::handoff` seeds `session_cursors` at `prior.next_seq` so the consumer uses the production dedup-below+snap-above path (matching `resume_sessions`), not the strict reject-gap legacy trap. (v0.13.0)\n [OK] REQ-HAZARD-DAEMON-HOSTED-LIVENESS required: [impl, unit, int] stages: -doc +impl +unit +int\n Daemon-hosted perches (Psyche, spt-hosted Self) derive liveness from the daemon endpoint table + info.json status, never is_process_alive(info.pid) (2.5)\n [OK] REQ-HAZARD-DAEMON-SCHED-NONBLOCKING required: [impl, unit] stages: -doc +impl +unit -int\n--\n B3: `spt daemon stop` then an immediate `spt daemon start` does NOT race — stop fully completes before it returns. Today request_stop (seedmap.rs:240-255) returns on the KIND_STOPPING ack (sent seedmap.rs:174-176) BEFORE the seed socket unbinds, so a following is_running ping (daemon.rs:375) wins the exit window and start reports ALREADY_RUNNING (operator: daemon stop → STOPPED then start → ALREADY_RUNNING). FIX: unbind/stop-gate the seed socket BEFORE acking KIND_STOPPING, OR request_stop waits for a ping-to-fail before returning. Unit: stop then immediate is_running()==false. (v0.12.0)\n [OK] REQ-HAZARD-DAEMON-STOP-REAP required: [impl, unit] stages: -doc +impl +unit -int\n Breap: `spt daemon stop` REAPS the spt-hosted children it spawned — no orphaned psyche/harness processes. Today a stop leaves ~8 orphaned claude-spt-psyche.exe + spt.exe: Psyches are spawned DETACHED (runtime.rs:342-356, the Child is dropped — 'Detached' ~349) and the livehost stop flag Arc is NEVER raised (brainproc.rs:227-230 holds it 'for symmetry'). FIX: on stop, raise the livehost stop flag AND kill the spawned psyche/spt-hosted children — via a Windows job object / Unix process-group so the children die with the daemon (not detached-immortal). Folds with B3 (both the stop path). (v0.12.0)\n [OK] REQ-HAZARD-DEFERRED-DRAIN required: [impl, unit] stages: -doc +impl +unit -int\n--\n A pointer-mode (delegated / GhReleaseManaged) adapter whose binary/manifest is not yet extracted is reported with a CLEAR diagnostic, never silently dropped. Today such an adapter reads its manifest LIVE from source_dir (registry.rs manifest_dir ~146/149); a deferred / un-extracted install makes load_manifest fail → registered() (~410, filter_map(.ok())) SILENTLY DROPS the row → downstream ADAPTER_UNRESOLVED + a cryptic os-error-2 on `spt adapter use`. FIX: surface a clear diagnostic at the resolver + at `adapter use` (name the adapter + the deferred/missing-manifest cause + the fix), not a silent filter-drop and not a bare os-error-2; consider an eager manifest copy at register time so host_binaries survive before the binary download completes. doyle Finding A.

Today only the [session.self] command ARGV is {id}-substituted; the [env] inject value is NEITHER substituted NOR applied — manifest.schema.json promises EnvVar.value = 'Value to inject (with substitution)' but prepare_harness_spawn fills only argv and SpawnReq carries no env, so a [env.SPT_ENDPOINT_ID].value='{id}' arrives EMPTY. A FLAGLESS harness (bare `claude`, no argv slot for {id}) then routes the id via [env] → empty → SessionStart sees empty $SPT_ENDPOINT_ID → seeds-by-PPID instead of binding → ZERO perch → NO_PERCH (the actual wall-b bind blocker; perri hard-repro'd). SILENT failure (empty inject, no error). FIX (doyle ruled a): fill every [env] inject value from the SAME {key} catalog as argv/role (mirror F-009 TEMPLATE fill, whole-string fill_template for an env value), thread it through SpawnReq.env → the broker sets it on the spawned PTY child. Correctness fix — schema already promises it, NO manifest change, NO new binary. PAIRS with REQ-SEND-SPT-HOSTED to make endpoint run fully work. doyle F-013. (post-v0.10.0)\n [OK] REQ-HAZARD-ENVELOPE-CR-LINESAFE required: [impl, unit] stages: -doc +impl +unit -int\n Envelope CR-linesafety (4.1): the line-framed EVENT codec must neutralize raw carriage returns — `event_body_escape` folds CRLF/lone-CR to the codec's representable linebreak (`\\n`→` `) BEFORE framing, so a body carrying `\\r` (Windows `echo`/CRLF text crossing nodes) cannot survive into the single-line envelope and trigger a receiver terminal CR→col0 overwrite that corrupts the frame.

Rationale: `spt whoami` is a thin alias of `endpoint list` — a just-online agent running `whoami` must see its OWN perch, or it gets an omitted-self view ('chaos'). FIX: drop the `--local` flag + its `--detail` conflict test + the v0.10.0 REQ-PICKER-5 hint line (cli.rs:1678) + cmd_list_local; the bare list merges local perches into the subnet view; fix the whoami alias path accordingly. Run `cargo run -p xtask -- gen` (docs-drift, DEFAULT target). (v0.12.1)\n [OK] REQ-ENDPOINT-PURGE required: [doc, impl, unit, int] stages: +doc +impl +unit +int\n--\n A legitimately dead PTY child (real crash/kill) + an undrained operator pump must NOT wedge the broker for all other clients. ROOT (v0.12.0 real-harness defect): loopback attach output is a blocking write_all into a bounded 64KB tokio duplex (nethost.rs:1040,1090); when the operator's rc pump stops draining (tab closed) the buffer fills and write_all blocks forever (the 'loopback never hangs' assumption at nethost.rs:1103 is false), parking a worker in the 2-worker net runtime (nethost.rs:640); a couple of these saturate BOTH workers → every new attach / `endpoint run` stalls right after 'PUMP_IPC_READER: spawned' → 30s FIRST_EVENT_GRACE → 'no output / dead or wedged'; `daemon stop` cannot join the stuck workers. DISTINCT from the removed B1 path-(c) mutex deadlock. DISPOSITION = PROVE-DON'T-CHANGE (doyle GATE-PASS @e883f45, 2026-06-18): this ROOT is the SUPERSEDED v0.12.0 hypothesis — the post-L0 code ALREADY prevents the wedge, so NO fail-fast / worker-count code was added. serve_attach forwards fire-and-forget (net_stream_send op_id=None) and the broker-side send_stream is already BROKER-QUIC-DEADLINE-bounded (bounded_block_on, 10s); the loopback duplex is drained broker-INTERNALLY by the operator row's own read pump (RecvHalf::Loopback, retentive_cap==0 → evict-not-park) so a dead rc (a dropped IPC subscriber) never backs peer_w up; bounded_block_on parks the BROKER DISPATCH thread, not a net worker → no worker-pool exhaustion (full mechanism in the required_stages comment). Folds the status=online sub-check: a dead spt-hosted endpoint is marked OFFLINE within one reconcile tick on abrupt child death (broker exit-waiter reaps the session → B2 sees it absent) — PROVEN, no change. (v0.12.1)\n [OK] REQ-HAZARD-BIND-CWD-UNSET required: [impl, unit, int] stages: -doc +impl +unit +int\n A bound endpoint's `info.cwd` is SET at bind so a freshly-created perch appears under its own project tab. ROOT (found, v0.13.0): `info.cwd` is NEVER set on bind — `cmd_bind` (spt-hosted) and `bind_from_seed` (harness-hosted) never thread cwd into `establish_perch`/`rec.cwd`. FIX: `cmd_bind` reads its own `current_dir` (the broker spawned it in `project_cwd`); `bind_from_seed` passes `seed.cwd` (already captured at seed time, currently DISCARDED). DISTINCT from REQ-PICKER-HISTORY-FRESH (v0.12.1) — that unioned cwd-origin into picker MEMBERSHIP but tested merge_origin_project with a PROVIDED origin; it never asserted `info.cwd` is actually set on bind, so a real `endpoint run` perch still had an empty cwd and the union had nothing to union. This is the v0.12.1 P1 'appears under its own project right away' claim that was REFUTED in the changelog — delivered for real here. (v0.13.0)\n [OK] REQ-HAZARD-BRAIN-RESPAWN-PATH required: [doc, impl, unit, int] stages: +doc +impl +unit +int\n--\n The broker bounds every brain-waiting QUIC op (dial / open_stream / send_stream) so a black-holed or dead peer fails PROMPTLY with an ORDINARY error the broker REPLIES, never an unbounded await. The bound (< the brain's 30s PUMP_PEER_IO_TIMEOUT so the BROKER fires first) surfaces to the pump as a normal broker error reply → peer_outcome's non-TimedOut arm → drop conn + redial next tick, the round CONTINUES and the heartbeat keeps advancing — it must NEVER manifest as the brain's own read-deadline (the A-half poison → supervised-restart path REQ-HAZARD-PUMP-IPC-DEADLINE guards). Exactly-once is preserved: a timed-out journaled op fails INSIDE its apply_once closure so no phantom conn_id/stream_id is recorded and a fresh tick re-dials cleanly. The happy path is unchanged (a live peer completes with zero added latency; the bound only bites a non-responsive peer). This is the ROOT-cause cure for the 2.2h hfenduleam pump wedge — a dead roster peer whose QUIC path the broker awaited unbounded — recurring on hfenduleam 2026-06-16.\n [OK] REQ-HAZARD-BROKER-SEED-WIRE-SKEW required: [doc, impl, unit] stages: +doc +impl +unit -int\n A daemon-state wire-format change (e.g. the v0.9.0 adapter-agnostic Seed) does NOT take effect until a DELIBERATE full broker restart: the broker serves the seed-control channel and is RESIDENT across a brain-only self-update (ADR-0004 no-terminate-during-update forbids auto-killing it), so a NEW-version CLI talking to a still-resident OLD broker fails the seed handshake — the old broker cannot deserialize the new Seed (its formerly-required `adapter` field is gone) and drops the conn without an ack, which surfaces to the CLI as a raw UnexpectedEof 'failed to fill whole buffer'. spt-core must (a) surface an ACTIONABLE diagnostic on that seed-ack EOF (name the stale-broker cause + the `spt daemon stop` fix — the broker restarts on the next api call), never the cryptic io error; and (b) document the operational rule (a deliberate broker restart is required on any daemon-state wire change — NOT automatic) + the FORWARD discipline (daemon-state/Seed schema changes stay additive + serde-default so a resident OLD broker tolerates a NEW CLI across a brain-only update; note this would NOT have rescued 0.9.0 itself, since the old broker's `adapter` was a required field). perri PREP-4 FINDING 1 (v0.9.0 CLI vs stale 0.8.x broker).\n [OK] REQ-HAZARD-CASCADE-WIPE-GUARD required: [impl, unit] stages: -doc +impl +unit -int\n No hard-delete of a parent hosting non-empty children (6.3)\n [OK] REQ-HAZARD-CHILD-CONSOLE-FLASH required: [impl, unit] stages: +doc +impl +unit -int\n--\n [--] REQ-HAZARD-CONTROLLER-WRITER-REORDER required: [doc, impl, unit, int] stages: +doc +impl -unit -int\n Two `controller_writer` threads must never race ONE brain↔broker connection's socket. ROOT (doyle, instrumented RACEDIAG repro on kitsubito): on a brain-restart re-serve the handoff brain registers as controller on the SAME session TWICE over the SAME `Brain::conn` socket — (1) `Brain::handoff` eagerly `subscribe(prior.session_id, prior.next_seq=1)` → `become_controller(from_seq=1)`, initial=[1], spawns writer-A (writes seq 1); (2) `serve_attach` re-handles the replayed `Request{from_seq:0}` → `attach_as(sid,0)` → `become_controller(from_seq=0)`, initial=[0,1], spawns writer-B (writes 0 then 1). `become_controller` (broker.rs) drops the prior `ControllerSink` (its `tx`) but does NOT stop the prior writer thread — writer-A keeps flushing its owned `initial` batch, and both writers hold clones of the same `SharedSend` (`Arc>`) with NO inter-thread ordering. When writer-A's seq 1 wins the socket before writer-B's seq 0, the strict legacy consumer (brain.rs read_event reject-gap path) sees `output gap: got seq 1 want 0` → the test `attach_survives_target_brain_restart_exactly_once` panics at `.expect(\"re-serve\")` OR HANGS in `render_until` (serve thread died on the gap → MARKER_TWO never reaches the wire). `prior.next_seq` is life1's CONSUMPTION cursor, NOT life2's connection state — life2's socket has been sent NOTHING, so a `from_seq=0` full replay on a connection that already streamed seq 1 is contradictory. Snap-above tolerance ALONE can't fix it (it would dedup-drop the late seq 0 → byte loss → the exactly-once byte-identity assert fails). PRE-EXISTING, surfaced by the v0.13.0 green-both-runners release gate; P1b is INNOCENT (its diff touches only input-ack machinery, proven mechanically + the test passes post-P1b in isolation). Sibling flaky cluster: `inject_control_wedge::g2`, `broker::spawn_env_reaches_child`. INVARIANT: on a single brain↔broker connection the controller output-frame stream is monotonic non-decreasing in seq (modulo dedup re-sends); exactly ONE `controller_writer` is ever live per connection; a SUPERSEDED writer writes NO further frames; a re-serve never replays a seq below what the connection already received. FIX (doyle design, V0.13.0-P1C-CONTROLLER-WRITER-REORDER-PLAN.md, three parts): (1) PRIMARY — `Brain::handoff` no longer eagerly `subscribe`s-as-controller; `serve_attach`'s `attach_as(sid,0)` is the SOLE controller registration + replay for that connection (handoff is test-only per the brain.rs comment; no production caller depends on the eager subscribe — production resumes via `cold_start`+`resume_sessions`). (2) BROKER HARDENING — `controller_writer` is epoch-gated: `controller_epoch` becomes a shared `Arc`, the writer snapshots its own epoch and checks the shared one before each frame (initial-batch AND live loop), returning the moment it is superseded — so a double-registration can never silently keep a superseded writer flushing (W1-safe: never blocks the drain under `Mutex`). (3) DEFENSE-IN-DEPTH — `Brain::handoff` seeds `session_cursors` at `prior.next_seq` so the consumer uses the production dedup-below+snap-above path (matching `resume_sessions`), not the strict reject-gap legacy trap. (v0.13.0)\n [OK] REQ-HAZARD-DAEMON-HOSTED-LIVENESS required: [impl, unit, int] stages: -doc +impl +unit +int\n Daemon-hosted perches (Psyche, spt-hosted Self) derive liveness from the daemon endpoint table + info.json status, never is_process_alive(info.pid) (2.5)\n [OK] REQ-HAZARD-DAEMON-SCHED-NONBLOCKING required: [impl, unit] stages: -doc +impl +unit -int\n--\n B3: `spt daemon stop` then an immediate `spt daemon start` does NOT race — stop fully completes before it returns. Today request_stop (seedmap.rs:240-255) returns on the KIND_STOPPING ack (sent seedmap.rs:174-176) BEFORE the seed socket unbinds, so a following is_running ping (daemon.rs:375) wins the exit window and start reports ALREADY_RUNNING (operator: daemon stop → STOPPED then start → ALREADY_RUNNING). FIX: unbind/stop-gate the seed socket BEFORE acking KIND_STOPPING, OR request_stop waits for a ping-to-fail before returning. Unit: stop then immediate is_running()==false. (v0.12.0)\n [OK] REQ-HAZARD-DAEMON-STOP-REAP required: [impl, unit] stages: -doc +impl +unit -int\n Breap: `spt daemon stop` REAPS the spt-hosted children it spawned — no orphaned psyche/harness processes. Today a stop leaves ~8 orphaned claude-spt-psyche.exe + spt.exe: Psyches are spawned DETACHED (runtime.rs:342-356, the Child is dropped — 'Detached' ~349) and the livehost stop flag Arc is NEVER raised (brainproc.rs:227-230 holds it 'for symmetry'). FIX: on stop, raise the livehost stop flag AND kill the spawned psyche/spt-hosted children — via a Windows job object / Unix process-group so the children die with the daemon (not detached-immortal). Folds with B3 (both the stop path). (v0.12.0)\n [OK] REQ-HAZARD-DEFERRED-DRAIN required: [impl, unit] stages: -doc +impl +unit -int\n--\n A pointer-mode (delegated / GhReleaseManaged) adapter whose binary/manifest is not yet extracted is reported with a CLEAR diagnostic, never silently dropped. Today such an adapter reads its manifest LIVE from source_dir (registry.rs manifest_dir ~146/149); a deferred / un-extracted install makes load_manifest fail → registered() (~410, filter_map(.ok())) SILENTLY DROPS the row → downstream ADAPTER_UNRESOLVED + a cryptic os-error-2 on `spt adapter use`. FIX: surface a clear diagnostic at the resolver + at `adapter use` (name the adapter + the deferred/missing-manifest cause + the fix), not a silent filter-drop and not a bare os-error-2; consider an eager manifest copy at register time so host_binaries survive before the binary download completes. doyle Finding A.

Today only the [session.self] command ARGV is {id}-substituted; the [env] inject value is NEITHER substituted NOR applied — manifest.schema.json promises EnvVar.value = 'Value to inject (with substitution)' but prepare_harness_spawn fills only argv and SpawnReq carries no env, so a [env.SPT_ENDPOINT_ID].value='{id}' arrives EMPTY. A FLAGLESS harness (bare `claude`, no argv slot for {id}) then routes the id via [env] → empty → SessionStart sees empty $SPT_ENDPOINT_ID → seeds-by-PPID instead of binding → ZERO perch → NO_PERCH (the actual wall-b bind blocker; perri hard-repro'd). SILENT failure (empty inject, no error). FIX (doyle ruled a): fill every [env] inject value from the SAME {key} catalog as argv/role (mirror F-009 TEMPLATE fill, whole-string fill_template for an env value), thread it through SpawnReq.env → the broker sets it on the spawned PTY child. Correctness fix — schema already promises it, NO manifest change, NO new binary. PAIRS with REQ-SEND-SPT-HOSTED to make endpoint run fully work. doyle F-013. (post-v0.10.0)\n [OK] REQ-HAZARD-ENVELOPE-CR-LINESAFE required: [impl, unit] stages: -doc +impl +unit -int\n Envelope CR-linesafety (4.1): the line-framed EVENT codec must neutralize raw carriage returns — `event_body_escape` folds CRLF/lone-CR to the codec's representable linebreak (`\\n`→` `) BEFORE framing, so a body carrying `\\r` (Windows `echo`/CRLF text crossing nodes) cannot survive into the single-line envelope and trigger a receiver terminal CR→col0 overwrite that corrupts the frame.

The implementation is DONE and compiles; you write ONLY tests + tag them. Do NOT change the fix code. Do NOT weaken any assertion.\n\n## Context — the bug + the fix (already landed)\nDesign doc: `V0.13.0-P1C-CONTROLLER-WRITER-REORDER-PLAN.md` (repo root). Hazard: `docs/KNOWN-HAZARDS.md` §7.21. REQ: `traceable-reqs.toml` id `REQ-HAZARD-CONTROLLER-WRITER-REORDER`, required_stages `[\"doc\",\"impl\",\"unit\",\"int\"]` (doc+impl already satisfied; you must satisfy **unit** + **int**).\n\nROOT: on a brain-restart re-serve, the handoff brain registered as controller on the SAME session TWICE over the SAME `Brain::conn` socket → two `controller_writer` threads raced one socket → non-monotonic on-wire seq (`got seq 1 want 0`) → `crates/spt-daemon/tests/attach.rs::attach_survives_target_brain_restart_exactly_once` flaky (panic at `.expect(\"re-serve\")` or HANG in `render_until`).\n\nTHE FIX (3 parts, all in place — read them):\n1. `crates/spt-daemon/src/brain.rs` `Brain::handoff` (~line 330): dropped the eager `brain.subscribe(prior.session_id, prior.next_seq)` call; NOW seeds `session_cursors.insert(prior.session_id, prior.next_seq)` and issues NO eager subscribe. The re-serve's `attach_as(sid,0)` is the sole controller registration.\n2. `crates/spt-daemon/src/broker.rs`: `OutputLog.controller_epoch` is now `Arc`. `become_controller` (~line 360) does `let epoch = self.controller_epoch.fetch_add(1, AcqRel) + 1;` and passes `epoch` + `Arc::clone(&self.controller_epoch)` into `controller_writer`. `controller_writer` (~line 716) checks `if controller_epoch.load(Acquire) != epoch { return; }` BEFORE each frame on BOTH the initial-batch loop AND the live `rx.recv()` loop — so a SUPERSEDED writer flushes nothing further.\n3. (defense) the seeded `session_cursors` routes the consumer through `read_event`'s dedup-below + snap-above path (brain.rs ~582), not the strict reject-gap legacy path (~599).\n\nINVARIANT to prove: on one brain↔broker connection the controller seq stream is monotonic non-decreasing; exactly one live `controller_writer` per connection; a superseded writer writes nothing further.\n\n## What to write\n\n### UNIT (in `crates/spt-daemon/src/broker.rs` `#[cfg(test)] mod tests` — white-box; `become_controller`/`controller_writer`/`OutputLog` are private, in-crate tests can reach them):\n- **Epoch-gate keystone**: build an `OutputLog`, append seq 0 and seq 1 to the ring, then call `become_controller` TWICE on the SAME `SharedSend` (a real socket/socketpair you read the other end of) — first `from_seq=1` (writer-A, initial=[1]), then `from_seq=0` (writer-B, initial=[0,1]). Drain the socket and assert the bytes that arrive are **monotonic non-decreasing in seq** and **byte-exact** — i.e. writer-A's superseded `seq 1` must NOT appear before writer-B's `seq 0` (post-fix: writer-A is epoch-gated silent → the wire shows a clean 0,1; never 1,0,1). Find how existing broker unit tests construct a `SharedSend` / read frames (grep for `SharedSend`, `socketpair`, `write_frame`, existing `become_controller`/`add_viewer`/`controller_writer` tests) and mirror that harness.

The implementation is DONE and compiles; you write ONLY tests + tag them. Do NOT change the fix code. Do NOT weaken any assertion.\n\n## Context — the bug + the fix (already landed)\nDesign doc: `V0.13.0-P1C-CONTROLLER-WRITER-REORDER-PLAN.md` (repo root). Hazard: `docs/KNOWN-HAZARDS.md` §7.21. REQ: `traceable-reqs.toml` id `REQ-HAZARD-CONTROLLER-WRITER-REORDER`, required_stages `[\"doc\",\"impl\",\"unit\",\"int\"]` (doc+impl already satisfied; you must satisfy **unit** + **int**).\n\nROOT: on a brain-restart re-serve, the handoff brain registered as controller on the SAME session TWICE over the SAME `Brain::conn` socket → two `controller_writer` threads raced one socket → non-monotonic on-wire seq (`got seq 1 want 0`) → `crates/spt-daemon/tests/attach.rs::attach_survives_target_brain_restart_exactly_once` flaky (panic at `.expect(\"re-serve\")` or HANG in `render_until`).\n\nTHE FIX (3 parts, all in place — read them):\n1. `crates/spt-daemon/src/brain.rs` `Brain::handoff` (~line 330): dropped the eager `brain.subscribe(prior.session_id, prior.next_seq)` call; NOW seeds `session_cursors.insert(prior.session_id, prior.next_seq)` and issues NO eager subscribe. The re-serve's `attach_as(sid,0)` is the sole controller registration.\n2. `crates/spt-daemon/src/broker.rs`: `OutputLog.controller_epoch` is now `Arc`. `become_controller` (~line 360) does `let epoch = self.controller_epoch.fetch_add(1, AcqRel) + 1;` and passes `epoch` + `Arc::clone(&self.controller_epoch)` into `controller_writer`. `controller_writer` (~line 716) checks `if controller_epoch.load(Acquire) != epoch { return; }` BEFORE each frame on BOTH the initial-batch loop AND the live `rx.recv()` loop — so a SUPERSEDED writer flushes nothing further.\n3. (defense) the seeded `session_cursors` routes the consumer through `read_event`'s dedup-below + snap-above path (brain.rs ~582), not the strict reject-gap legacy path (~599).\n\nINVARIANT to prove: on one brain↔broker connection the controller seq stream is monotonic non-decreasing; exactly one live `controller_writer` per connection; a superseded writer writes nothing further.\n\n## What to write\n\n### UNIT (in `crates/spt-daemon/src/broker.rs` `#[cfg(test)] mod tests` — white-box; `become_controller`/`controller_writer`/`OutputLog` are private, in-crate tests can reach them):\n- **Epoch-gate keystone**: build an `OutputLog`, append seq 0 and seq 1 to the ring, then call `become_controller` TWICE on the SAME `SharedSend` (a real socket/socketpair you read the other end of) — first `from_seq=1` (writer-A, initial=[1]), then `from_seq=0` (writer-B, initial=[0,1]). Drain the socket and assert the bytes that arrive are **monotonic non-decreasing in seq** and **byte-exact** — i.e. writer-A's superseded `seq 1` must NOT appear before writer-B's `seq 0` (post-fix: writer-A is epoch-gated silent → the wire shows a clean 0,1; never 1,0,1). Find how existing broker unit tests construct a `SharedSend` / read frames (grep for `SharedSend`, `socketpair`, `write_frame`, existing `become_controller`/`add_viewer`/`controller_writer` tests) and mirror that harness. To make the race observable/deterministic pre-fix, force writer-A to actually flush seq 1 before writer-B exists (e.g. let writer-A run/block on the socket, sync, then the second become_controller) — POST-FIX must be DETERMINISTICALLY green regardless of interleaving (the gate guarantees it); that is the real bar. If full pre-fix determinism is impractical, it is acceptable for the test to be deterministic-green post-fix and flaky-red pre-fix — but VERIFY the red by temporarily reverting ONLY the epoch-gate `return` and confirming the test fails, then restore.\n- **handoff seeds session_cursors**: a unit (brain.rs `#[cfg(test)]` if there's a brain unit harness, else fold into the broker int) asserting that after `Brain::handoff`, `session_cursor(prior.session_id) == Some(prior.next_seq)` and that handoff did NOT send a subscribe frame (no eager controller registration).

Not backlog noise — these are decided directions parked for sequencing reasons. Keep this list short and real.\n4\t\n5\t| Feature | Cut from | Why deferred | Trigger to revisit |\n6\t|---|---|---|---|\n7\t| Scrollback on-disk spillover | terminal wrapper v1 | In-memory ring covers the common case; spillover adds a persistence/rotation story | First long-running session that overflows the ring usefully, or any \"scroll back further than the buffer\" user need |\n8\t| Sidecar adapter process (long-running, wire-protocol) | harness contract v1 | Manifest + `spt.exe` subcommand surface covers v1 harnesses; sidecar only earns its keep for streaming / in-memory cross-event state | A harness outgrows manifest+hooks (needs streaming or stateful coordination) |\n9\t| Manifest `include` / composition (option C) | manifest v1 | Single flat manifest per harness is enough until a harness wants to override only part of a section | First sub-project that needs to inherit spt-core defaults but override one section |\n10\t| Concrete Shell types (GameRobot, in-session-inject) — **OS-notification shell carved out: ships M5** as the dogfood proof (user decision 2026-06-04, M5-PLAN §Scope decisions) | Shell concept v1 | Model is locked; concrete surfaces are large, platform-specific, and not needed for core | First real use case for a driven surface (e.g. the 2D-world experiment) |\n11\t| PresenceChannel implementation (broker, dispatch/bind/thread) | endpoint types v1 | Depends on presence gossip + Shells + multi-instance routing; only the seams ship v1. **M5 ships presence *resolution* (gossip + most-recently-active API) — its future substrate; the endpoint stays deferred** (user decision 2026-06-04). **M5-D6 seam note:** the substrate now exists — the gossiped datum (`Instance.last_active_ms`, riding the registry's epoch lease + replication) and the one MRA API (`spt-daemon::presence`). A future PresenceChannel's dispatch/bind/thread styles consume exactly this datum plus the broker PresenceLog seam (REQ-EP-4); nothing about the endpoint type needs a new gossip channel. | Once Shells exist and the subnet registry is stable |\n12\t| OS-level input-activity presence signal (7a-A) | presence v1 | Per-platform, privacy-loaded; agent-interaction heartbeat covers the v1 goal. **Note:** distinct from the v1 broker *sensing* user input on a PTY it already holds (spt-hosted) — that is in v1 and is NOT OS-wide input monitoring | Opt-in enhancement after agent-interaction presence proves out |\n13\t| Instantiate-anywhere + consent gate | Instances V1-mid | Remote launch over network is additive once remote-drive of running instances works. Consent *model* is now designed (CONTEXT §Consent & security gates); **the framework (grant store + escalation + pre-consent flags) ships M5 with this capability id reserved-but-refusing** (user decision 2026-06-04) — the capability lands into it later. Defers with it: the remote-fork arm, cross-node shell spawn, `shell_wake_spawn_anywhere` *behavior* (grant shape ships M5). **M5-D5b note:** remote `spt suspend/wake ` shipped (the rest-op wire family, remote-drive trust class) — it *moves existing instances between rest states only*; the remote-**fork** arm (creating an instance on a node that has none) stays here, riding instantiate-anywhere's consent gate. A wake addressed to a node with no local instance refuses with `WAKE_NO_REACHABLE_INSTANCE` naming this deferral. | Revisit-trigger met (remote-drive shipped M4); held back by user decision — capability drops into the M5 consent framework when picked up |\n14\t| Remote command execution on another node | off-node reach-back v1 | Highest-risk capability; needs the consent/security gate. Workarounds exist (message a local agent; interact with local agent directly). **M5 ships the framework with this capability id reserved-but-refusing** (user decision 2026-06-04) | Designed alongside instantiate-anywhere's consent gate |\n15\t| Shell-binary (and harness-binary) sandboxing | Shell concept v1 | A capability toolset bounds what the *agent* can ask, not what the *binary* can do with its OS perms. Baseline stance: running any adapter/shell binary = a disclosed, accepted trust risk for all spt-core users | If/when untrusted third-party shell/harness binaries become common enough to warrant OS-level sandboxing |\n16\t| Concrete Shell adapters (e.g. GameRobot) + the shell binaries themselves | Shell concept v1 | The Shell *model*, manifest schema, perch layout, and `api` surface are now specified; concrete shells are large, platform-specific, and not needed for core | First real driven-surface use case |\n17\t| REQ-CONSENT int evidence (interactive escalation E2E) | M5 closeout (D9b rule-5) | The escalation prompt''s end-to-end leg needs a real harness session answering a real consent prompt — loopback-faking it would prove nothing; the grant store + gate + CLI are impl/unit-proven | The downstream rebuilt spt plugin (v1 acceptance) — its first gated spawn IS the int evidence |\n18\t| REQ-INSTALL-4 int evidence (`spt adapter add --github` against a real repo) | M5 closeout (D9b rule-5) | Needs a real clone target; impl/unit cover manifest-first validation + registration. The standalone `SaberMage/spt-shell-notify` repo now makes this trivially possible | First milestone that touches adapter lifecycle again — one E2E cloning the notify repo |\n19\t| OS-service registration at install (REQ-INSTALL-1's third leg: systemd user service / Windows service or scheduled task for the always-on guarantee) | installer v0.1 (M6-D2, grill decision 3) | Daemon auto-start on any `spt` invocation covers dev-stage use; the minimal non-interactive script stays non-OS-entangled (also serves REQ-INSTALL-2's repackaging stance). Honest gap: a node is unreachable after reboot until something invokes `spt` | First always-on deployment need (headless/server node, or the GUI milestone's background expectations) |\n20\t| Tier 2 agent-docs: MCP doc/resource server + `spt --help --json` structured-help mode (REQ-DOCS-4 legs) | docs v0.1 (M6-D3/D5, DOCS-STRATEGY §v0.1 grill) | Tier 1 covers the integration surface: the schemars-derived manifest schema + llms.txt/llms-full.txt + the generated CLI reference; `--help --json` is low marginal value over that reference, the MCP server is the standout *later* fit | First integrating dev-agent that outgrows llms.txt + schema (or the `spt-claude-code` work surfacing a concrete MCP-resource need) |\n21\t| Subnet attachment verbs: `spt subnet detach [--auto]` / `attach [--auto]` (daemon keeps running, stops/starts advertising + connecting for that subnet; `--auto` persists the startup default), `spt subnet leave ` (elevation-gated), maybe `spt subnet disband ` (elevation + current TOTP) | M7 grill (user spec 2026-06-06; CONTEXT §subnet attachment) | The attached/detached *term* + the all-attached banner ship M7; the per-subnet serve-state machinery (selective advertise/connect, persisted flags) is its own deliverable | M8 CLI nounification, or first multi-subnet user needing selective participation |\n22\t| Linux elevation model (user-ratified direction 2026-06-06): (1) install symlinks the binary into a sudo-reachable path (e.g. `/usr/local/bin`) so `sudo spt` resolves; (2) first `sudo spt` detects elevation and prompts once for the DEFAULT USER ACCOUNT — thereafter any `sudo spt` daemon launch always runs the daemon (and state) under that account, never root (kills the `sudo HOME=$HOME` dance and the root-owned-state hazard) | M7 acceptance run (gravity: `sudo: spt: command not found`, then the HOME-universe split) | Needs installer + first-run-state design; Windows elevation has no equivalent problem (same user profile) | M8, with the installer's next touch |\n23\t| Windows firewall registration for the installed binary: a DETACHED daemon never shows the first-bind firewall prompt, so inbound UDP (mDNS + QUIC meet/pairing) is silently dropped — found as the M7 acceptance NO_SEED_HOLDER (dev/test paths had accumulated allow rules; the install path had none). Options: an elevated install leg adds the rule (`New-NetFirewallRule`), and/or the daemon self-detects blocked inbound and renders it as the \"no connection\" state in `subnet status` + the coming-online banner | M7 acceptance run (2026-06-06) | User-scope installer is deliberately non-OS-entangled (REQ-INSTALL-2); needs the elevated-install / OS-service design anyway | M8, with the OS-service + Linux-elevation install work |\n24\t| ~~**Non-admin daemon spawn (both OSes)**~~ **SHIPPED 2026-06-06** (KNOWN-HAZARDS 5.7, REQ-HAZARD-ELEVATED-DAEMON-SPAWN): de-elevated spawn at `spawn_detached` (Windows: UAC linked token via `CreateProcessWithTokenW`; Linux: drop child to SUDO_UID/GID) + `Daemon::run` entry guard + the unix `spt` main-entry sudo drop (whole process re-anchored to the invoker's universe, elevation kept PROVEN for the gated commands).

FIX: a node-LEVEL carrier — `SubnetRegistry.node_labels` (node→label) + a `NodeLabelUpdate` feed record riding the existing registry replication stream as an untagged `RegistryFeedRecord` variant (instance bytes unchanged → mixed-version fleet safe, old peers skip the new lines). Merged under the same epoch lease, evicted with the node, gated identically to instance feeds. The pump emits one label record per served subnet regardless of endpoint count; `node_status_rows` reads it to NAME an endpoint-less peer without counting it as an endpoint (`[0/0]` holds, no liveness effect).

FIX: a new `ServeProbeRecord` (spt-net `serveprobe`) + daemon `serveprobe` handler/requester ask the peer \"serving subnet X?\", answered from its own `AttachmentStore::is_detached` ∧ membership (the same signal the pump/responder gate on); the dispatcher classifies it by the `serve_probe` first-line field; `wansend::probe_node_serving` dials (proves reachable) THEN asks, so a detached-but-alive peer reads offline within a cadence.

There is NO origin fetch, so the **first node in a fleet — or any isolated/solo node — cannot get a new release without a peer that already staged it** (the fleet converges by gossip, but only *after* a maintainer seeds the first node via the release-publish path). The installer DOES fetch from GitHub (`github.com/SaberMage/spt-releases/releases/latest/download/` + `SHA256SUMS`, `installer/install.sh:57-73`) but only at install time, outside the daemon's signed-release gate, and never re-runs. FIX = a new **origin-fetch leg** that downloads the per-platform artifact + its `.release.json` (the `SignedRelease` metadata) from the release origin and feeds them through the **SAME** `plan_verified` gate (`verify_metadata` two-key signature/channel/expiry/rollback + `verify_artifact` SHA-256, `update.rs:157`/`release.rs`), then `cache.stage()` — after which the EXISTING consent-notif / `spt update apply` flow is unchanged. So it reuses ~all the machinery; it only adds an HTTPS GET from the origin as an alternate SOURCE to the P2P `request_update` pull. Surface: `spt update fetch [--channel ] [--tag vX.Y.Z]` (default: latest on the node's pinned channel); optionally a daemon-config `origin_check` cadence so a lone node self-bootstraps alongside P2P, then re-propagates to peers normally. **Key design note:** the daemon has **zero HTTP surface today** — all transport is iroh QUIC; `reqwest` is only a transitive dep (via iroh), not reachable. This leg needs a deliberate HTTPS-client decision (add `reqwest`/a minimal client as a direct dep, vs shell out to `curl`/`Invoke-WebRequest` like the installer — fragile). Honor the channel pin (`release-keys.json`) + the monotonic rollback floor; configurable repo (mirror `SPT_INSTALL_REPO`). The two-key signed-release anchor keeps the GitHub transport **untrusted-but-verified** (strictly stronger than the installer's HTTPS+SHA256SUMS-only first fetch).

Flakes intermittently on the **kitsubito** self-hosted Linux runner (likely AF_UNIX path collision / stale socket file under the runner's reused workspace — Windows named pipes don't hit it). Cost the v0.3.2 release a full red CI run + a `--failed` rerun (2026-06-09); same code passed clean on rerun → flake, not a logic bug. FIX = make the test bind deterministic: unlink-before-bind, OR abstract-namespace socket (Linux `@`-prefixed, no filesystem entry), OR per-test `TempDir` isolation so each bind has a guaranteed-fresh path. Applies to every `served_broker`/socket-name test helper, not just applyhost | Triaged during v0.3.2 release (2026-06-09) — flake, shipped over it | Non-blocking: a real flake that taxes CI (one red cycle + rerun per hit) but never gates a correct build; hardening is test-infra work, not product. Held to keep the v0.3.2 release moving | **Restoration D1/D7** (`RESTORATION-PLAN.md`) — D1/D7 add real process-spawn tests on the kitsubito runner; fix the bind determinism there rather than fighting flakes through the milestone (M8 is complete) |\n39\t| **`spt update fetch` single→set shape-upgrade at same version (REQ-UPD-8 transitional trap)**: `cmd_update_fetch` sets the rollback floor = `staged_version` (the monotonic counter), and the gate is a plain `candidate > floor`. A node that fetched+staged version N as a platform **single** (pre-0.3.2 fetch behavior) can never re-fetch version N as a multi-platform **set** — same counter → `Rollback{current:N, candidate:N}`. Bites the **seed-node bootstrap**: the first node to origin-`fetch` a release applies the single for its OWN platform, then can't re-stage the same version as a set → has no Windows/other-platform artifact to SERVE peers over P2P. Surfaced live in the v0.3.2 cross-platform rig verify (2026-06-09): kitsubito staged+applied the v6 single, then its v6-set re-fetch was refused; unblock was a manual `releases/` cache-clear before re-fetch. Counter vs semver is working as designed (counter = trust spine, semver = cosmetic) — the gap is purely shape-blind: the floor compares version only, ignoring single-vs-set. FIX options: (a) allow a same-version re-fetch when staged shape is `single` and an available `set` is strictly-richer (shape-upgrade allowance), or (b) seed-server flow stages the SET before applying its own single, or (c) a `--force`/`--restage` flag. NOTE — only bites the one migration hop onto 0.3.2; once a node is on 0.3.2 with a fresh cache, future releases are vN+1 and stage clean. Mint a REQ before fixing | v0.3.2 cross-platform rig verify (2026-06-09; user-flagged via session watch) | Transitional-only: the workaround (cache-clear before staging the set) is reliable and was used to complete the v0.3.2 fleet roll; a code fix only saves the manual clear on same-version shape upgrades, which won't recur after the 0.3.2 hop | A future release that again changes staged-artifact SHAPE at a same/non-incrementing counter, or making `spt update fetch` self-sufficient for solo seed-nodes (pairs with the origin-source bootstrap row above) |\n40\t| **On-disk `current_exe` reconcile after auto-rollback (the D6-2 reboot residual)**: readiness-gated auto-rollback (ADR-0018 Q7, restoration D6-2) is **record-driven selection** — after a rollback the broker's supervisor keeps spawning the last-known-good `.old-N` binary, chosen from the durable `RolledBack` record, so the rescue survives a reboot for free **with no file rename at the failure instant** (the brittle path the design rejected). But the bytes on disk at `current_exe` are STILL the quarantined bad version. The supervisor rescues the **brain** (it never execs `current_exe` while a `RolledBack` record stands), but an OS-service / autostart / `ensure_running` relaunch execs `current_exe` **as the broker** — and **if the bad binary panics before broker bind, the node is down until manual intervention** (record-driven selection cannot save a binary that won't boot). FIX = a calm-path reconcile: on the next clean `apply` (or a broker self-reconcile once stable), rename the good bytes over `current_exe` so the on-disk seat matches the running selection. Deliberately NOT a failure-time rename | Restoration D6-2 (ADR-0018 Q7, open-call-3, 2026-06-10) — record-driven selection rescues the brain; the on-disk seat reconcile defers | The reboot-survives-via-record path is correct NOW for the common case (broker boots, supervisor re-selects the good binary); the residual only bites when the broker process itself re-execs the quarantined `current_exe` and that binary won't even bind. Failure-time rename is the brittle path the design rejected; the calm-path reconcile needs the next clean-apply seam | First field rollback where the broker (not just the brain) restarts onto the quarantined on-disk bytes — or the D7 process-survival proof exercising a broker re-exec after rollback |\n41\t| **Quarantine operator override (`spt update apply --force` — the note-i escape hatch)**: D6-2's quarantine guard refuses re-applying a version that auto-rolled-back on this node (the `RolledBack` record is the marker; clears naturally when N+1 stages). But a version whose failure was **environmental** (a transient boot condition, not bad bytes) leaves the node **permanently allergic** to a genuinely-good version with no escape but staging a newer one. FIX = an explicit operator override (`spt update apply --force`, or a `spt update unquarantine `) that clears the `RolledBack` marker and re-opens the apply for that version — a deliberate, operator-gated act, never automatic | Restoration D6-2 (ADR-0018 Q7, note-i, 2026-06-10) — quarantine ships; the override defers | The natural N+1 clear covers the common \"the next release fixes it\" path; the override only matters when the SAME version must be retried after an environmental fix. Operator-gated re-apply is a small CLI + record-clear, deferrable to the alarm/adapter era | First node permanently allergic to a genuinely-good version (environmental rollback), or the M8 update-CLI polish |\n42\t| **✅ RESOLVED — shipped v0.8.3 (REQ-HAZARD-BROKER-QUIC-DEADLINE, KNOWN-HAZARDS 7.8).** ~~Broker-side bound on brain-waiting QUIC ops (the pump-IPC-deadline B-half)~~: the brain-side deadline (REQ-HAZARD-PUMP-IPC-DEADLINE, KNOWN-HAZARDS 7.6) stops the single-threaded pump wedging when a peer black-holes, by bounding the pump's brain-IPC reads and escalating a TimedOut to a supervised restart. But the ROOT cause is broker-side: the broker's `net_open_stream` / `net_stream_send` / `net_dial` handlers make the brain wait on a QUIC operation to a dead peer with no bound of their own, so the brain only escapes via its own deadline (a 30s stall + a full pump restart each time). FIX = the broker must never make a brain wait unbounded on a QUIC op — bound those handlers broker-side (a QUIC-level timeout that returns an Error event promptly), so a black-holed peer fails the single `peer_step` cleanly (ordinary per-peer abort + redial) without poisoning the client or forcing a pump restart. The broker is RESIDENT by design (CONTEXT §\"broker update frequency: rare\"), so this cannot reach the deployed fleet without a broker-update path — hence deferred to the next planned broker-update batch rather than riding the brain-only v0.4.1 roll the A-half ships on. **Added motivation (Windows, KH 7.6):** the A-half's reader-thread carrier leaks ONE `pump-ipc-reader` thread per wedge event — on a supervised restart the old reader is left blocked in `read_frame` holding its `RecvHalf`, and interprocess split halves share one OS handle (closes only when BOTH drop), so on a named pipe the broker may never signal the disconnect and the old reader can park indefinitely (especially while the broker itself is wedged on the dead-peer QUIC await — the very thing B fixes). Bounded (one thread per actual wedge, not per restart round — the post-restart conn cache is fresh, so the dead peer is re-dialed, not re-wedged on a cached dead conn), but B is the real cure: bounding the broker's QUIC await makes the brain's read return promptly, so the reader thread is never left parked | Pump-stall diagnosis 2026-06-11 (doyle ruling A-now / B-deferred) | The brain-side A-half fixes the fleet NOW via the brain-only update machinery (v0.4.1 candidate) and makes the wedge self-heal in 5s instead of 2.2h; B is the deeper correctness fix but only reachable through the rare broker-update path.

But it deliberately does **not** build the machinery: the spt-core daemon has **no one-shot consumer today** — `alarm` exists only as an event *shape* (`spt-proto`) + relay handling (`psyrelay.rs:93`) + a test fixture; the actual \"wait until target, fire the TIMED PULSE\" timer lives in the **legacy owl listener in-memory** (BROKER-BRAIN-SPLIT-RESTORATION §7). Building the one-shot deadline machinery in the restoration milestone would ship **untested dead code** (violates activate-don't-pre-fail). FIX = port alarms into the daemon as a durable scheduler that rides the Q4 one-shot rule (persist target-time at creation, fire-if-due on every brain start, survive both crash and update).

Two pieces deferred, both because they have **no consumer yet** (Shell=M10, GUI/frontend pane, Gateway agent-window — none exist): (a) the **autonomous file-watch→publish freshness nudge** (a watcher that re-projects + publishes when the log grows on its own, vs today's pull/push-driven publishes) — CONTEXT.md \"session digest\" anticipates this as \"an incremental normalize story (design-phase concern)\"; (b) the **Option-C opt-in persistence re-home** (the byte-feed engine drove per-turn persistence off `pty_digest.persist`, now deleted; re-homing it onto a `[history]`/digest config seam now = a manifest surface with nothing reading it).

Keep this list short and real.\n\n| Feature | Cut from | Why deferred | Trigger to revisit |\n|---|---|---|---|\n| Scrollback on-disk spillover | terminal wrapper v1 | In-memory ring covers the common case; spillover adds a persistence/rotation story | First long-running session that overflows the ring usefully, or any \"scroll back further than the buffer\" user need |\n| Sidecar adapter process (long-running, wire-protocol) | harness contract v1 | Manifest + `spt.exe` subcommand surface covers v1 harnesses; sidecar only earns its keep for streaming / in-memory cross-event state | A harness outgrows manifest+hooks (needs streaming or stateful coordination) |\n| Manifest `include` / composition (option C) | manifest v1 | Single flat manifest per harness is enough until a harness wants to override only part of a section | First sub-project that needs to inherit spt-core defaults but override one section |\n| Concrete Shell types (GameRobot, in-session-inject) — **OS-notification shell carved out: ships M5** as the dogfood proof (user decision 2026-06-04, M5-PLAN §Scope decisions) | Shell concept v1 | Model is locked; concrete surfaces are large, platform-specific, and not needed for core | First real use case for a driven surface (e.g. the 2D-world experiment) |\n| PresenceChannel implementation (broker, dispatch/bind/thread) | endpoint types v1 | Depends on presence gossip + Shells + multi-instance routing; only the seams ship v1. **M5 ships presence *resolution* (gossip + most-recently-active API) — its future substrate; the endpoint stays deferred** (user decision 2026-06-04). **M5-D6 seam note:** the substrate now exists — the gossiped datum (`Instance.last_active_ms`, riding the registry's epoch lease + replication) and the one MRA API (`spt-daemon::presence`). A future PresenceChannel's dispatch/bind/thread styles consume exactly this datum plus the broker PresenceLog seam (REQ-EP-4); nothing about the endpoint type needs a new gossip channel. | Once Shells exist and the subnet registry is stable |\n| OS-level input-activity presence signal (7a-A) | presence v1 | Per-platform, privacy-loaded; agent-interaction heartbeat covers the v1 goal. **Note:** distinct from the v1 broker *sensing* user input on a PTY it already holds (spt-hosted) — that is in v1 and is NOT OS-wide input monitoring | Opt-in enhancement after agent-interaction presence proves out |\n| Instantiate-anywhere + consent gate | Instances V1-mid | Remote launch over network is additive once remote-drive of running instances works. Consent *model* is now designed (CONTEXT §Consent & security gates); **the framework (grant store + escalation + pre-consent flags) ships M5 with this capability id reserved-but-refusing** (user decision 2026-06-04) — the capability lands into it later. Defers with it: the remote-fork arm, cross-node shell spawn, `shell_wake_spawn_anywhere` *behavior* (grant shape ships M5). **M5-D5b note:** remote `spt suspend/wake ` shipped (the rest-op wire family, remote-drive trust class) — it *moves existing instances between rest states only*; the remote-**fork** arm (creating an instance on a node that has none) stays here, riding instantiate-anywhere's consent gate. A wake addressed to a node with no local instance refuses with `WAKE_NO_REACHABLE_INSTANCE` naming this deferral. | Revisit-trigger met (remote-drive shipped M4); held back by user decision — capability drops into the M5 consent framework when picked up |\n| Remote command execution on another node | off-node reach-back v1 | Highest-risk capability; needs the consent/security gate. Workarounds exist (message a local agent; interact with local agent directly). **M5 ships the framework with this capability id reserved-but-refusing** (user decision 2026-06-04) | Designed alongside instantiate-anywhere's consent gate |\n| Shell-binary (and harness-binary) sandboxing | Shell concept v1 | A capability toolset bounds what the *agent* can ask, not what the *binary* can do with its OS perms. Baseline stance: running any adapter/shell binary = a disclosed, accepted trust risk for all spt-core users | If/when untrusted third-party shell/harness binaries become common enough to warrant OS-level sandboxing |\n| Concrete Shell adapters (e.g. GameRobot) + the shell binaries themselves | Shell concept v1 | The Shell *model*, manifest schema, perch layout, and `api` surface are now specified; concrete shells are large, platform-specific, and not needed for core | First real driven-surface use case |\n| REQ-CONSENT int evidence (interactive escalation E2E) | M5 closeout (D9b rule-5) | The escalation prompt''s end-to-end leg needs a real harness session answering a real consent prompt — loopback-faking it would prove nothing; the grant store + gate + CLI are impl/unit-proven | The downstream rebuilt spt plugin (v1 acceptance) — its first gated spawn IS the int evidence |\n| REQ-INSTALL-4 int evidence (`spt adapter add --github` against a real repo) | M5 closeout (D9b rule-5) | Needs a real clone target; impl/unit cover manifest-first validation + registration. The standalone `SaberMage/spt-shell-notify` repo now makes this trivially possible | First milestone that touches adapter lifecycle again — one E2E cloning the notify repo |\n| OS-service registration at install (REQ-INSTALL-1's third leg: systemd user service / Windows service or scheduled task for the always-on guarantee) | installer v0.1 (M6-D2, grill decision 3) | Daemon auto-start on any `spt` invocation covers dev-stage use; the minimal non-interactive script stays non-OS-entangled (also serves REQ-INSTALL-2's repackaging stance). Honest gap: a node is unreachable after reboot until something invokes `spt` | First always-on deployment need (headless/server node, or the GUI milestone's background expectations) |\n| Tier 2 agent-docs: MCP doc/resource server + `spt --help --json` structured-help mode (REQ-DOCS-4 legs) | docs v0.1 (M6-D3/D5, DOCS-STRATEGY §v0.1 grill) | Tier 1 covers the integration surface: the schemars-derived manifest schema + llms.txt/llms-full.txt + the generated CLI reference; `--help --json` is low marginal value over that reference, the MCP server is the standout *later* fit | First integrating dev-agent that outgrows llms.txt + schema (or the `spt-claude-code` work surfacing a concrete MCP-resource need) |\n| Subnet attachment verbs: `spt subnet detach [--auto]` / `attach [--auto]` (daemon keeps running, stops/starts advertising + connecting for that subnet; `--auto` persists the startup default), `spt subnet leave ` (elevation-gated), maybe `spt subnet disband ` (elevation + current TOTP) | M7 grill (user spec 2026-06-06; CONTEXT §subnet attachment) | The attached/detached *term* + the all-attached banner ship M7; the per-subnet serve-state machinery (selective advertise/connect, persisted flags) is its own deliverable | M8 CLI nounification, or first multi-subnet user needing selective participation |\n| Linux elevation model (user-ratified direction 2026-06-06): (1) install symlinks the binary into a sudo-reachable path (e.g. `/usr/local/bin`) so `sudo spt` resolves; (2) first `sudo spt` detects elevation and prompts once for the DEFAULT USER ACCOUNT — thereafter any `sudo spt` daemon launch always runs the daemon (and state) under that account, never root (kills the `sudo HOME=$HOME` dance and the root-owned-state hazard) | M7 acceptance run (gravity: `sudo: spt: command not found`, then the HOME-universe split) | Needs installer + first-run-state design; Windows elevation has no equivalent problem (same user profile) | M8, with the installer's next touch |\n| Windows firewall registration for the installed binary: a DETACHED daemon never shows the first-bind firewall prompt, so inbound UDP (mDNS + QUIC meet/pairing) is silently dropped — found as the M7 acceptance NO_SEED_HOLDER (dev/test paths had accumulated allow rules; the install path had none). Options: an elevated install leg adds the rule (`New-NetFirewallRule`), and/or the daemon self-detects blocked inbound and renders it as the \"no connection\" state in `subnet status` + the coming-online banner | M7 acceptance run (2026-06-06) | User-scope installer is deliberately non-OS-entangled (REQ-INSTALL-2); needs the elevated-install / OS-service design anyway | M8, with the OS-service + Linux-elevation install work |\n| ~~**Non-admin daemon spawn (both OSes)**~~ **SHIPPED 2026-06-06** (KNOWN-HAZARDS 5.7, REQ-HAZARD-ELEVATED-DAEMON-SPAWN): de-elevated spawn at `spawn_detached` (Windows: UAC linked token via `CreateProcessWithTokenW`; Linux: drop child to SUDO_UID/GID) + `Daemon::run` entry guard + the unix `spt` main-entry sudo drop (whole process re-anchored to the invoker's universe, elevation kept PROVEN for the gated commands). Remaining Linux follow-up = the install-symlink + default-account election row below (M8) | M7 acceptance run (2026-06-06) | The membership-implies-reachability activation made elevated commands daemon-spawners — correct goal, wrong token | DONE (real elevated-spawn verification on both OSes rides the next acceptance pass) |\n| ~~**Ghost registry row eviction**~~ **SHIPPED 2026-06-06** (KNOWN-HAZARDS 4.10, REQ-HAZARD-REGISTRY-GHOST-ROWS): silent-peer decay — rows from a node unheard for `registry_evict_after_ms` (default 300s ≈ 10 pump cadences) evict on the registry pump tick, snapshots rewritten; own rows never decay. STALE trust rows for a dead identity still need a manual prune verb (below) | M7 acceptance run (2026-06-06) | Needs a decay/eviction policy (e.g. drop rows unrefreshed for N pump cadences; trust-row pruning verb) | DONE (fleet cleanup: 09ef831e ghost rows on both BIGNET nodes decay once the new build deploys) |\n| Trust-row prune verb (`spt subnet prune ` or similar): registry GHOST rows now decay (4.10), but the dead identity's TRUST rows persist by design (trust is a user decision) — they cost dead dials every pump tick and clutter status views. BIGNET carries two such rows (09ef831e, both sides) | Ghost-eviction fix (2026-06-06) | Trust mutation = security surface; wants the elevation gate + the M8 noun shapes | M8 CLI nounification |\n| Elevated spt-hosted endpoints — a consented elevation satellite: the broker lives inside the always-unelevated daemon (KH 5.7), so spt-hosted children are unelevated by construction; there is NO silent unelevated→elevated path on either OS (that is UAC/sudo's whole point). An agent needing admin powers is harness-hosted-elevated today (works: TCP listeners + talk-down pipes). The spt-hosted form needs a per-grant CONSENTED elevation: UAC prompt / polkit spawns a small elevated PTY-host satellite holding only the elevated children, linked back to the unelevated daemon — rides the REQ-CONSENT-2 escalation framework (allow-once/always) + the reserved-but-refusing capability pattern | Elevated-endpoint design grill (user 2026-06-06) | Real elevation-granting UX + a second privileged process = its own deliverable; the consent framework it rides already ships | First spt-hosted agent that needs admin powers (or the instantiate-anywhere milestone) |\n| ~~AMBIGUOUS render~~ **SHIPPED 2026-06-06** (rode the ghost-eviction fix): resolution refusals render valid copy-paste targets at the wansend boundary (`render_refusal`) — labels preferred, key-prefix on label collision, `subnet:id` for cross-subnet | M7 acceptance run (user 2026-06-06) | Pure render fix at the wansend/CLI boundary; carries into the M8 nounification sweep | DONE |\n| Post-join address seeding: the pairing ceremony holds a live, authenticated connection to the peer, but the peer pumps then re-find each other from scratch via id-only discovery (fresh node ids must propagate to n0 DNS first) — observed live as ~1 min to first `status --nodes` convergence after a join. Seed the pump's address cache from the ceremony connection (both sides) for instant first sync | M7 acceptance run (2026-06-06) | Convergence is correct, just slow on first contact; needs an addr-cache seam the pumps consult before the resolver | M8 polish |\n| Clock source priority for TOTP/rendezvous: query a well-known world clock (NTP) FIRST, fall back to local time — machines with skewed local clocks currently derive wrong steps/rendezvous tokens silently | M7 acceptance grill (user 2026-06-06) | Needs an NTP client dep + offset caching + offline fallback semantics; ±1 window covers small skew today | First field report of clock-skew join failures, or M8 polish |\n| CLI nounification (M8 candidate; ratified shape from the 2026-06-06 grill): `spt endpoint` namespace absorbs fork/suspend/wake/shutdown/rename/stop/digest + `access` (per-endpoint store — NOT subnet-scoped) + `description` (ex-`resources` blurb; bare = show, `set` = author); `spt endpoint list [--local\\|--subnet ]` = merged listing, default all-subnets grouped by subnet, SELF endpoint pinned distinctly at top (bare `spt endpoint` = this list); agent HOT PATH stays flat (`send`/`ring`/`ready`/`whoami`/`how-to`); `notify` → `spt subnet notify`; `notif` stays top-level (user-recall, cross-subnet); `spt daemon stop\\|status` noun (hidden `daemon` → `daemon run`); agent-endpoint `shutdown` keeps its name | M7 grill (2026-06-06) | Second surface-breaking reorg mid-acceptance; adapter window still open immediately after M7 closes | M8 planning — mint REQs first (rule 3) |\n| ~~Node label for an endpoint-less node (REQ-SUBNET-3 gap)~~ **SHIPPED 2026-06-08** (option 2 — node-level presence datum): a peer with **zero endpoints** rendered as a bare key-prefix in `status --nodes` because `node_label` only rode endpoint `Instance` rows. FIX: a node-LEVEL carrier — `SubnetRegistry.node_labels` (node→label) + a `NodeLabelUpdate` feed record riding the existing registry replication stream as an untagged `RegistryFeedRecord` variant (instance bytes unchanged → mixed-version fleet safe, old peers skip the new lines). Merged under the same epoch lease, evicted with the node, gated identically to instance feeds. The pump emits one label record per served subnet regardless of endpoint count; `node_status_rows` reads it to NAME an endpoint-less peer without counting it as an endpoint (`[0/0]` holds, no liveness effect). Chose option 2 over option 1 (trust-pin label at pairing) to avoid touching the SPAKE2 ceremony + un-dormanting warn-on-change (which couples with the REQ-SUBNET-7 machine_id re-pair overwrite) — option 2 is also live-updating on hostname change | M8 criterion-5 acceptance run (HFENDULEAM↔kitsubito, 2026-06-07; HF at `[0/0]` showed bare uuid to kitsubito) | Cosmetic; deferred per user decision 2026-06-07, fixed 2026-06-08 (user picked option 2) | DONE (real-hardware verify rides the next acceptance/deploy pass) |\n| **Instant + never-seen peer hostname via pairing-time capture (REQ-SUBNET-3 follow-up; the deferred \"option 1\")**: the shipped node-level label (option 2) is GOSSIP-ONLY, so a peer's name is learned only from a pump round while it is alive. Two residual gaps remain after the eviction fix below: (a) ~1 gossip cadence to appear after a join (the joiner trust-pins by pubkey with `label=None`; the hostname arrives next pump round — enlyzeam↔kitsubito converged to `ENLYZEAM` after a cadence, fine but not instant); (b) a peer that stops WITHIN a cadence of pairing is never named (its label never gossiped). FIX: capture the peer hostname **at pairing → the persistent trust-pin label**. Needs (1) BIDIRECTIONAL pairing intro — the joiner→responder `NodeIntro` (label+machine_id) already exists; add responder→joiner so BOTH sides capture each other's hostname; (2) wire `trust.record`'s `label` = peer hostname at both pin sites (`pairing/wire.rs` ~324 responder, ~435 initiator, both currently `None`); (3) handle the warn-on-change coupling with the REQ-SUBNET-7 machine_id re-pair overwrite (a legit machine reinstall = same machine_id, new key → repin, not a silent fail). **NOTE — the OFFLINE-loses-name half was a real bug, FIXED 2026-06-08** (not this deferred row): a *learned* node_label was being silence-decayed by `evict_nodes`, so an offline trusted member lost its name; `evict_nodes` now keeps labels (silence ≠ forget) and only an explicit `spt subnet prune` drops them (`evict_node_labels`). This row is the remaining INSTANT + NEVER-SEEN half | enlyzeam/kitsubito SPT_DEV diagnosis (user 2026-06-08) | The instant/never-seen half of REQ-SUBNET-3; pairs with the \"post-join address seeding\" row (same ceremony-connection seam, seed label + address both sides) — touches SPAKE2, so its own focused milestone | Next session — mint REQ for the trust-pin-label capture + bidirectional intro |\n| ~~Subnet-scoped liveness probe (REQ-SUBNET-5 detach gap)~~ **SHIPPED 2026-06-08** (REQ-SUBNET-5 int stage): `subnet status --nodes` showed a DETACHED peer as **online** because liveness fell to `Probe` → a raw transport dial by node-pubkey, which succeeded on the peer's still-bound daemon endpoint (one ALPN `spt-core/net/0` serves all subnets, so the dial was subnet-blind). FIX: a new `ServeProbeRecord` (spt-net `serveprobe`) + daemon `serveprobe` handler/requester ask the peer \"serving subnet X?\", answered from its own `AttachmentStore::is_detached` ∧ membership (the same signal the pump/responder gate on); the dispatcher classifies it by the `serve_probe` first-line field; `wansend::probe_node_serving` dials (proves reachable) THEN asks, so a detached-but-alive peer reads offline within a cadence. Probe LATENCY had shipped separately 2026-06-07 (`run_bounded` 2.5s + \"Checking remote nodes…\" notice). int evidence: `dispatcher_serves_a_subnet_serve_probe` (loopback E2E) | M8 criterion-5 acceptance run (HFENDULEAM↔kitsubito, 2026-06-07) | Real liveness-model fix on accepted M7 hybrid-liveness; deferred to keep acceptance moving (user decision 2026-06-07) | DONE (criterion-5 detach-flip now GREEN; real-hardware re-verify rides the next acceptance/deploy pass) |\n| **Subnet full-mesh visibility (PLANNED MILESTONE — `SUBNET-MESH-PLAN.md`)**: non-directly-paired members never see each other — a subnet is currently the PAIRING GRAPH, not a mesh (A↔B, C↔B; B offline → A and C invisible; even with B online, B doesn't relay). Root: pairwise TOFU trust (`trust.rs`) + own-rows-only gossip / no transitive relay (`peerloop.rs`, KH 4.10/7.5) + no member roster in the pairing seed transfer. FIX = member-AUTHENTICATED subnet data (seed-MAC and/or per-node signatures) unlocking transitive trust (seed-holder = member = trusted) + transitive gossip relay + roster propagation; MUST re-solve eviction/epoch-lease under relay (supersedes KH 4.10's \"no transitive gossip\" safety assumption). ADR-level; mint REQ-MESH-* first. Folds in the deferred pairing-time hostname capture + post-join address seeding (same roster/ceremony seam) | A→B→C invisibility test (user 2026-06-08) — confirmed two-gap design limitation, not a code defect | **DESIGN RATIFIED 2026-06-08** (grill): symmetric **seed-proof membership** + **roster-only relay** (rows stay own-authored, no third-party relay → KH 4.10/7.5 PRESERVED, not superseded). Full design = **ADR-0017**; reqs = **REQ-MESH-1..6** (inactive); plan = `SUBNET-MESH-PLAN.md`; glossary = CONTEXT §Pairing & trust. Folds in the pairing-time hostname-capture + post-join address-seeding rows (roster fields). Next: plan-phase over REQ-MESH-* | Next milestone — design done 2026-06-08; build pending plan-phase |\n| `xtask debug-converge` — automated convergence watcher for debug rollout (the REQ-UPD-6 first-slice item ADR-0016 names): watch every expected debug-pinned reachable lab node until all report the target version applied, else a per-node timeout table (Offline / StagedAwaitingConsent / BlockedByBrokerResources / Rejected{reason}). Activates REQ-UPD-6's `int` stage. Full build plan: `docs/DEBUG-CONVERGE-PLAN.md` | REQ-UPD-6 first slice (2026-06-06) | The first slice ships manual \"Apply and observe\" (`DEBUG-ROLLOUT.md`); the watcher's one genuinely new surface is a node status-query wire leg (no-fetch `{channel, applied_version, last_outcome}` over the existing update handshake) — assembly otherwise | First multi-node debug rollout where hand-walking nodes is the bottleneck, or M8 update polish |\n| **Origin-source update bootstrap (`spt update fetch` — pull the latest signed release from GitHub into the existing verify→stage→apply pipeline)**: today update DISCOVERY is **peer-only** (REQ-UPD-1: a daemon pulls offers from roster peers via `request_update`; `propagate.rs`/`peerloop.rs`). There is NO origin fetch, so the **first node in a fleet — or any isolated/solo node — cannot get a new release without a peer that already staged it** (the fleet converges by gossip, but only *after* a maintainer seeds the first node via the release-publish path). The installer DOES fetch from GitHub (`github.com/SaberMage/spt-releases/releases/latest/download/` + `SHA256SUMS`, `installer/install.sh:57-73`) but only at install time, outside the daemon's signed-release gate, and never re-runs. FIX = a new **origin-fetch leg** that downloads the per-platform artifact + its `.release.json` (the `SignedRelease` metadata) from the release origin and feeds them through the **SAME** `plan_verified` gate (`verify_metadata` two-key signature/channel/expiry/rollback + `verify_artifact` SHA-256, `update.rs:157`/`release.rs`), then `cache.stage()` — after which the EXISTING consent-notif / `spt update apply` flow is unchanged. So it reuses ~all the machinery; it only adds an HTTPS GET from the origin as an alternate SOURCE to the P2P `request_update` pull. Surface: `spt update fetch [--channel ] [--tag vX.Y.Z]` (default: latest on the node's pinned channel); optionally a daemon-config `origin_check` cadence so a lone node self-bootstraps alongside P2P, then re-propagates to peers normally. **Key design note:** the daemon has **zero HTTP surface today** — all transport is iroh QUIC; `reqwest` is only a transitive dep (via iroh), not reachable. This leg needs a deliberate HTTPS-client decision (add `reqwest`/a minimal client as a direct dep, vs shell out to `curl`/`Invoke-WebRequest` like the installer — fragile). Honor the channel pin (`release-keys.json`) + the monotonic rollback floor; configurable repo (mirror `SPT_INSTALL_REPO`). The two-key signed-release anchor keeps the GitHub transport **untrusted-but-verified** (strictly stronger than the installer's HTTPS+SHA256SUMS-only first fetch). Mint **REQ-UPD-7** (origin-source fetch) first. | Update subsystem v1 (ADR-0016, REQ-UPD family) — P2P-pull only by design | v1 update flow is peer-propagation by design (seed one node, the fleet converges by gossip); origin-fetch is additive and the maintainer seed path covered bootstrap so far. No HTTP client is wired into the daemon yet | First isolated / first-in-fleet node that must update with no peer to pull from; or making `spt update` self-sufficient for solo / single-node users (user flagged the gap 2026-06-08) |\n| **Test broker socket-bind hardening (CI-flake removal)**: `applyhost` tests' `served_broker` helper does `Broker::bind(name).expect(\"bind broker\")` (`crates/spt-daemon/src/applyhost.rs:293`) where `name` = `spt-daemon-d7b-{pid}-{seq}.sock`. Flakes intermittently on the **kitsubito** self-hosted Linux runner (likely AF_UNIX path collision / stale socket file under the runner's reused workspace — Windows named pipes don't hit it). Cost the v0.3.2 release a full red CI run + a `--failed` rerun (2026-06-09); same code passed clean on rerun → flake, not a logic bug. FIX = make the test bind deterministic: unlink-before-bind, OR abstract-namespace socket (Linux `@`-prefixed, no filesystem entry), OR per-test `TempDir` isolation so each bind has a guaranteed-fresh path. Applies to every `served_broker`/socket-name test helper, not just applyhost | Triaged during v0.3.2 release (2026-06-09) — flake, shipped over it | Non-blocking: a real flake that taxes CI (one red cycle + rerun per hit) but never gates a correct build; hardening is test-infra work, not product. Held to keep the v0.3.2 release moving | **Restoration D1/D7** (`RESTORATION-PLAN.md`) — D1/D7 add real process-spawn tests on the kitsubito runner; fix the bind determinism there rather than fighting flakes through the milestone (M8 is complete) |\n| **`spt update fetch` single→set shape-upgrade at same version (REQ-UPD-8 transitional trap)**: `cmd_update_fetch` sets the rollback floor = `staged_version` (the monotonic counter), and the gate is a plain `candidate > floor`. A node that fetched+staged version N as a platform **single** (pre-0.3.2 fetch behavior) can never re-fetch version N as a multi-platform **set** — same counter → `Rollback{current:N, candidate:N}`. Bites the **seed-node bootstrap**: the first node to origin-`fetch` a release applies the single for its OWN platform, then can't re-stage the same version as a set → has no Windows/other-platform artifact to SERVE peers over P2P. Surfaced live in the v0.3.2 cross-platform rig verify (2026-06-09): kitsubito staged+applied the v6 single, then its v6-set re-fetch was refused; unblock was a manual `releases/` cache-clear before re-fetch. Counter vs semver is working as designed (counter = trust spine, semver = cosmetic) — the gap is purely shape-blind: the floor compares version only, ignoring single-vs-set. FIX options: (a) allow a same-version re-fetch when staged shape is `single` and an available `set` is strictly-richer (shape-upgrade allowance), or (b) seed-server flow stages the SET before applying its own single, or (c) a `--force`/`--restage` flag. NOTE — only bites the one migration hop onto 0.3.2; once a node is on 0.3.2 with a fresh cache, future releases are vN+1 and stage clean. Mint a REQ before fixing | v0.3.2 cross-platform rig verify (2026-06-09; user-flagged via session watch) | Transitional-only: the workaround (cache-clear before staging the set) is reliable and was used to complete the v0.3.2 fleet roll; a code fix only saves the manual clear on same-version shape upgrades, which won't recur after the 0.3.2 hop | A future release that again changes staged-artifact SHAPE at a same/non-incrementing counter, or making `spt update fetch` self-sufficient for solo seed-nodes (pairs with the origin-source bootstrap row above) |\n| **On-disk `current_exe` reconcile after auto-rollback (the D6-2 reboot residual)**: readiness-gated auto-rollback (ADR-0018 Q7, restoration D6-2) is **record-driven selection** — after a rollback the broker's supervisor keeps spawning the last-known-good `.old-N` binary, chosen from the durable `RolledBack` record, so the rescue survives a reboot for free **with no file rename at the failure instant** (the brittle path the design rejected). But the bytes on disk at `current_exe` are STILL the quarantined bad version. The supervisor rescues the **brain** (it never execs `current_exe` while a `RolledBack` record stands), but an OS-service / autostart / `ensure_running` relaunch execs `current_exe` **as the broker** — and **if the bad binary panics before broker bind, the node is down until manual intervention** (record-driven selection cannot save a binary that won't boot). FIX = a calm-path reconcile: on the next clean `apply` (or a broker self-reconcile once stable), rename the good bytes over `current_exe` so the on-disk seat matches the running selection. Deliberately NOT a failure-time rename | Restoration D6-2 (ADR-0018 Q7, open-call-3, 2026-06-10) — record-driven selection rescues the brain; the on-disk seat reconcile defers | The reboot-survives-via-record path is correct NOW for the common case (broker boots, supervisor re-selects the good binary); the residual only bites when the broker process itself re-execs the quarantined `current_exe` and that binary won't even bind. Failure-time rename is the brittle path the design rejected; the calm-path reconcile needs the next clean-apply seam | First field rollback where the broker (not just the brain) restarts onto the quarantined on-disk bytes — or the D7 process-survival proof exercising a broker re-exec after rollback |\n| **Quarantine operator override (`spt update apply --force` — the note-i escape hatch)**: D6-2's quarantine guard refuses re-applying a version that auto-rolled-back on this node (the `RolledBack` record is the marker; clears naturally when N+1 stages). But a version whose failure was **environmental** (a transient boot condition, not bad bytes) leaves the node **permanently allergic** to a genuinely-good version with no escape but staging a newer one. FIX = an explicit operator override (`spt update apply --force`, or a `spt update unquarantine `) that clears the `RolledBack` marker and re-opens the apply for that version — a deliberate, operator-gated act, never automatic | Restoration D6-2 (ADR-0018 Q7, note-i, 2026-06-10) — quarantine ships; the override defers | The natural N+1 clear covers the common \"the next release fixes it\" path; the override only matters when the SAME version must be retried after an environmental fix. Operator-gated re-apply is a small CLI + record-clear, deferrable to the alarm/adapter era | First node permanently allergic to a genuinely-good version (environmental rollback), or the M8 update-CLI polish |\n| **✅ RESOLVED — shipped v0.8.3 (REQ-HAZARD-BROKER-QUIC-DEADLINE, KNOWN-HAZARDS 7.8).** ~~Broker-side bound on brain-waiting QUIC ops (the pump-IPC-deadline B-half)~~: the brain-side deadline (REQ-HAZARD-PUMP-IPC-DEADLINE, KNOWN-HAZARDS 7.6) stops the single-threaded pump wedging when a peer black-holes, by bounding the pump's brain-IPC reads and escalating a TimedOut to a supervised restart. But the ROOT cause is broker-side: the broker's `net_open_stream` / `net_stream_send` / `net_dial` handlers make the brain wait on a QUIC operation to a dead peer with no bound of their own, so the brain only escapes via its own deadline (a 30s stall + a full pump restart each time). FIX = the broker must never make a brain wait unbounded on a QUIC op — bound those handlers broker-side (a QUIC-level timeout that returns an Error event promptly), so a black-holed peer fails the single `peer_step` cleanly (ordinary per-peer abort + redial) without poisoning the client or forcing a pump restart. The broker is RESIDENT by design (CONTEXT §\"broker update frequency: rare\"), so this cannot reach the deployed fleet without a broker-update path — hence deferred to the next planned broker-update batch rather than riding the brain-only v0.4.1 roll the A-half ships on. **Added motivation (Windows, KH 7.6):** the A-half's reader-thread carrier leaks ONE `pump-ipc-reader` thread per wedge event — on a supervised restart the old reader is left blocked in `read_frame` holding its `RecvHalf`, and interprocess split halves share one OS handle (closes only when BOTH drop), so on a named pipe the broker may never signal the disconnect and the old reader can park indefinitely (especially while the broker itself is wedged on the dead-peer QUIC await — the very thing B fixes). Bounded (one thread per actual wedge, not per restart round — the post-restart conn cache is fresh, so the dead peer is re-dialed, not re-wedged on a cached dead conn), but B is the real cure: bounding the broker's QUIC await makes the brain's read return promptly, so the reader thread is never left parked | Pump-stall diagnosis 2026-06-11 (doyle ruling A-now / B-deferred) | The brain-side A-half fixes the fleet NOW via the brain-only update machinery (v0.4.1 candidate) and makes the wedge self-heal in 5s instead of 2.2h; B is the deeper correctness fix but only reachable through the rare broker-update path. Mint a REQ (broker-side QUIC-op bound) before building | Next planned broker-update batch (folds in with any other resident-broker change) |\n| **Durable in-daemon alarm scheduler (one-shot deadline machinery — the Q4/V3 deferral)**: the broker/brain restoration (ADR-0018 Q4) fixes the *rule* for one-shot scheduled events — persist the absolute `target-time` at creation; every brain start (update *or* crash) reads it and fires-if-due; **never reset on crash** (a user's \"remind me at 3pm\" is a commitment that must outlive any restart). But it deliberately does **not** build the machinery: the spt-core daemon has **no one-shot consumer today** — `alarm` exists only as an event *shape* (`spt-proto`) + relay handling (`psyrelay.rs:93`) + a test fixture; the actual \"wait until target, fire the TIMED PULSE\" timer lives in the **legacy owl listener in-memory** (BROKER-BRAIN-SPLIT-RESTORATION §7). Building the one-shot deadline machinery in the restoration milestone would ship **untested dead code** (violates activate-don't-pre-fail). FIX = port alarms into the daemon as a durable scheduler that rides the Q4 one-shot rule (persist target-time at creation, fire-if-due on every brain start, survive both crash and update). The periodic-loop half of Q4 (anchor+interval derive) DOES ship in restoration D5; only the one-shot machinery defers here. | Restoration milestone D5 (ADR-0018 Q4/V3, 2026-06-09) — rule fixed, machinery deferred | The daemon has no one-shot consumer to exercise it; the periodic-deadline mechanism (the phase-significant pulse loop) ships in D5 and proves out the disk-anchored-deadline pattern the alarm port will reuse | The alarm port — porting the legacy in-memory alarm timer into the daemon as a durable scheduler (first real one-shot consumer); reuses the D5 disk-deadline pattern + the Q4 one-shot rule |\n| **Autonomous session-digest freshness + Option-C re-home (M9 ADR-0008 amendment deferral)**: M9 re-founded the digest as an ON-DEMAND projection of normalized session logs (`spt-term::projection`; `spt-daemon::digest::project_endpoint_digest`) — snapshot-pull and the structured-delta-stream CONTRACT ship, deltas driven by pulls / `api digest-entry` pushes. Two pieces deferred, both because they have **no consumer yet** (Shell=M10, GUI/frontend pane, Gateway agent-window — none exist): (a) the **autonomous file-watch→publish freshness nudge** (a watcher that re-projects + publishes when the log grows on its own, vs today's pull/push-driven publishes) — CONTEXT.md \"session digest\" anticipates this as \"an incremental normalize story (design-phase concern)\"; (b) the **Option-C opt-in persistence re-home** (the byte-feed engine drove per-turn persistence off `pty_digest.persist`, now deleted; re-homing it onto a `[history]`/digest config seam now = a manifest surface with nothing reading it). Building either now = a speculative realtime subsystem with no reader (the M9-PLAN §9 \"no new realtime subsystem\" watch-item). | M9 Wave 3 / G3 (doyle ruling 2026-06-13) — snapshot-pull is the G3 bar, delta-stream contract ships | Both ride a live consumer: the digest works topology-independently TODAY (pull projects real content; a subscriber follows and gets push-driven deltas). Autonomous freshness only matters when a frontend pane streams it continuously; Option-C only matters when something reads the coarse activity log. Deferring honors CONTEXT.md's anticipated staging, not a scope cut | The **consuming-frontend milestone** that streams the digest live (Shell M10 drive/sensory pane, the GUI \"latest session output\" pane, or the Gateway agent-window) — wire the file-watch nudge + re-home Option-C onto a digest config seam then, with a real reader to exercise both |\n| **Two-origin `owl_message` context-tap subtype refinement (M10 ADR-0019 deferral)**: the two-origin merge's owl-message producer (`spt::api::startup` `deliver` closure) taps the live-agent **`emit` chokepoint**, so EVERY delivered frame — including resurfaced **notif** frames and shell-context rows — is recorded as a single coarse `owl_message` context-injection entry (`context_kind:\"owl_message\"`).

ROOT (doyle, instrumented RACEDIAG repro on kitsubito): on a brain-restart re-serve the handoff brain registers as controller on the SAME session TWICE over the SAME `Brain::conn` socket — (1) `Brain::handoff` eagerly `subscribe(prior.session_id, prior.next_seq=1)` → `become_controller(from_seq=1)`, initial=[1], spawns writer-A (writes seq 1); (2) `serve_attach` re-handles the replayed `Request{from_seq:0}` → `attach_as(sid,0)` → `become_controller(from_seq=0)`, initial=[0,1], spawns writer-B (writes 0 then 1). `become_controller` (broker.rs) drops the prior `ControllerSink` (its `tx`) but does NOT stop the prior writer thread — writer-A keeps flushing its owned `initial` batch, and both writers hold clones of the same `SharedSend` (`Arc>`) with NO inter-thread ordering. When writer-A's seq 1 wins the socket before writer-B's seq 0, the strict legacy consumer (brain.rs read_event reject-gap path) sees `output gap: got seq 1 want 0` → the test `attach_survives_target_brain_restart_exactly_once` panics at `.expect(\\\"re-serve\\\")` OR HANGS in `render_until` (serve thread died on the gap → MARKER_TWO never reaches the wire). `prior.next_seq` is life1's CONSUMPTION cursor, NOT life2's connection state — life2's socket has been sent NOTHING, so a `from_seq=0` full replay on a connection that already streamed seq 1 is contradictory. Snap-above tolerance ALONE can't fix it (it would dedup-drop the late seq 0 → byte loss → the exactly-once byte-identity assert fails). PRE-EXISTING, surfaced by the v0.13.0 green-both-runners release gate; P1b is INNOCENT (its diff touches only input-ack machinery, proven mechanically + the test passes post-P1b in isolation). Sibling flaky cluster: `inject_control_wedge::g2`, `broker::spawn_env_reaches_child`. INVARIANT: on a single brain↔broker connection the controller output-frame stream is monotonic non-decreasing in seq (modulo dedup re-sends); exactly ONE `controller_writer` is ever live per connection; a SUPERSEDED writer writes NO further frames; a re-serve never replays a seq below what the connection already received. FIX (doyle design, V0.13.0-P1C-CONTROLLER-WRITER-REORDER-PLAN.md, three parts): (1) PRIMARY — `Brain::handoff` no longer eagerly `subscribe`s-as-controller; `serve_attach`'s `attach_as(sid,0)` is the SOLE controller registration + replay for that connection (handoff is test-only per the brain.rs comment; no production caller depends on the eager subscribe — production resumes via `cold_start`+`resume_sessions`). (2) BROKER HARDENING — `controller_writer` is epoch-gated: `controller_epoch` becomes a shared `Arc`, the writer snapshots its own epoch and checks the shared one before each frame (initial-batch AND live loop), returning the moment it is superseded — so a double-registration can never silently keep a superseded writer flushing (W1-safe: never blocks the drain under `Mutex`). (3) DEFENSE-IN-DEPTH — `Brain::handoff` seeds `session_cursors` at `prior.next_seq` so the consumer uses the production dedup-below+snap-above path (matching `resume_sessions`), not the strict reject-gap legacy trap.

ROOT (doyle, instrumented RACEDIAG repro on kitsubito): on a brain-restart re-serve the handoff brain registers as controller on the SAME session TWICE over the SAME `Brain::conn` socket — (1) `Brain::handoff` eagerly `subscribe(prior.session_id, prior.next_seq=1)` → `become_controller(from_seq=1)`, initial=[1], spawns writer-A (writes seq 1); (2) `serve_attach` re-handles the replayed `Request{from_seq:0}` → `attach_as(sid,0)` → `become_controller(from_seq=0)`, initial=[0,1], spawns writer-B (writes 0 then 1). `become_controller` (broker.rs) drops the prior `ControllerSink` (its `tx`) but does NOT stop the prior writer thread — writer-A keeps flushing its owned `initial` batch, and both writers hold clones of the same `SharedSend` (`Arc>`) with NO inter-thread ordering. When writer-A's seq 1 wins the socket before writer-B's seq 0, the strict legacy consumer (brain.rs read_event reject-gap path) sees `output gap: got seq 1 want 0` → the test `attach_survives_target_brain_restart_exactly_once` panics at `.expect(\\\"re-serve\\\")` OR HANGS in `render_until` (serve thread died on the gap → MARKER_TWO never reaches the wire). `prior.next_seq` is life1's CONSUMPTION cursor, NOT life2's connection state — life2's socket has been sent NOTHING, so a `from_seq=0` full replay on a connection that already streamed seq 1 is contradictory. Snap-above tolerance ALONE can't fix it (it would dedup-drop the late seq 0 → byte loss → the exactly-once byte-identity assert fails). PRE-EXISTING, surfaced by the v0.13.0 green-both-runners release gate; P1b is INNOCENT (its diff touches only input-ack machinery, proven mechanically + the test passes post-P1b in isolation). Sibling flaky cluster: `inject_control_wedge::g2`, `broker::spawn_env_reaches_child`. INVARIANT: on a single brain↔broker connection the controller output-frame stream is monotonic non-decreasing in seq (modulo dedup re-sends); exactly ONE `controller_writer` is ever live per connection; a SUPERSEDED writer writes NO further frames; a re-serve never replays a seq below what the connection already received. FIX (doyle design, V0.13.0-P1C-CONTROLLER-WRITER-REORDER-PLAN.md, three parts): (1) PRIMARY — `Brain::handoff` no longer eagerly `subscribe`s-as-controller; `serve_attach`'s `attach_as(sid,0)` is the SOLE controller registration + replay for that connection (handoff is test-only per the brain.rs comment; no production caller depends on the eager subscribe — production resumes via `cold_start`+`resume_sessions`). (2) BROKER HARDENING — `controller_writer` is epoch-gated: `controller_epoch` becomes a shared `Arc
