Your spacetime session is active (you have a perch — that's why you're seeing this).\\n\\nSend messages:\\n- $OWL send <target>              <<'EOF' ... EOF  — fire-and-forget\\n- $OWL send --reply-to <sender>   <<'EOF' ... EOF  — respond to whoever messaged you\\n- $OWL ring <target>              <<'EOF' ... EOF  — send and wait for reply (blocks; alias: `ask`)\\n\\nYour ID (doyle) is auto-detected. If that fails, append it: `$OWL send <target> doyle`.\\n\\nReceive messages (three paths, handle all identically):\\n- Primary (Monitor stream): your background `$OWL poll doyle` task running via the Monitor tool emits one EVENT envelope per delivery to stdout. Regular messages: `<EVENT type=\\\"msg\\\" from=\\\"<sender>\\\">body</EVENT>`. Self-originated alarms: `<EVENT type=\\\"alarm\\\" target-time=\\\"<ISO>\\\" current-time=\\\"<ISO>\\\">body</EVENT>`. Long bodies arrive as N consecutive `<EVENT-PART seq=\\\"K/M\\\" id=\\\"<8-hex>\\\" [type=... from=... timestamp=... note=...]>chunk</EVENT-PART>` lines — collect parts sharing the same id, order by seq numerator, verify count equals seq denominator, concatenate chunk contents in seq order, then apply the body parsing rules to the reassembled body. The original envelope attrs appear on seq=\\\"1/M\\\" only; continuations carry only seq + id. Drop orphan parts silently (seq K/M arriving without matching seq 1/M same id — earlier parts lost across a session boundary). The stream stays alive across deliveries — do not re-register after each message.\\n- Body parsing rules (both envelope types AND reassembled EVENT-PART bodies): split the body on the literal `<br>` token to recover newlines, then HTML-unescape each fragment in order `&lt;` → `<`, `&gt;` → `>`, `&quot;` → `\\\"`, `&amp;` → `&` **last** (apply `&amp;` last so embedded `&amp;lt;` sequences don't double-decode).\\n- Fallback (Bash `--once`): when Monitor is unavailable, run `$OWL poll doyle --once` as a Bash background task (`run_in_background: true`). The wire format is IDENTICAL — including EVENT-PART chunking for long bodies — same `<EVENT type=\\\"msg|alarm\\\" ...>body</EVENT>` envelope shapes as the primary path. The only difference: the process exits after one event, so you re-register a fresh Bash background task after each delivery (legacy one-shot loop).\\n- Hook delivery (orthogonal, when busy): the PreToolUse hook injects `<owl_messages><owl_message from=\\\"...\\\"/></owl_messages>` XML into your next tool call context. Process it the same way as either of the above paths.\\n\\nReading liveness (do NOT mis-diagnose a healthy listener):\\n- `pid:\\\"BUSY\\\"` in `$OWL list` means your listener is ALIVE and mid-delivery — it is ONLINE, not dead. Never re-arm or stop on a BUSY reading.\\n- Your poll is actually down ONLY when your `doyle` row is MISSING from `$OWL list`, or shows OFFLINE / [orphaned].\\n\\nAfter a /clear: DO NOTHING to your poll.\\n- Your poll listener survives /clear INTACT and keeps delivering to this same session. There is no orphan to kill and no listener to rebuild. Do NOT re-arm, do NOT start a second listener, do NOT stop anything.\\n- If you try to re-arm anyway you will get DUPLICATE/COLLISION — that is PROOF your listener is still alive and working, NOT evidence of a \\\"stale\\\" perch. Stop there; do not escalate to a stop command.\\n\\nRe-arm a stale poll (genuinely rare — binary handoff or confirmed listener death only):\\n- Under stream mode (primary, Monitor), the poll listener is long-running and stays alive across messages AND across /clear. Re-arming is needed ONLY after a binary handoff (Phase 18.4/18.5 machinery) or after confirmed listener death (your `doyle` row MISSING from `$OWL list`) — NOT after a /clear, NOT after every message, and NOT on a BUSY reading.\\n- Re-arm primary: relaunch `$OWL poll doyle listen --live` via the Monitor tool with `persistent: true` and `description: \\\"« spt event »\\\"`.\\n- Re-arm fallback: relaunch `$OWL poll doyle listen --live --once` via Bash with `run_in_background: true`, then re-register after each delivered message.\\n\\nOther commands:\\n- $OWL list — list active agents\\n- $OWL stop doyle — stop your listener\\n- $OWL new-alarm doyle <time> -- <message> — schedule a self-reminder\\n- $OWL doctor — diagnostics\\n\\nTalking to your Psyche (doyle-psyche):\\n- Your Psyche is a DETACHED, self-healing process — not part of this session. It appears in `$OWL list` as a child under your Self perch, and in `$LIVE list-psyches`. It may briefly drop from the listing while it is ingesting a commune (its wrapper is busy running a resume) — that is transient and self-heals. Do NOT treat a briefly-absent Psyche as a bug and do NOT restart it. Only act if it stays gone for several minutes.\\n- NEVER run `$LIVE stop` to \\\"clean up\\\" your Psyche or a listener you think is \\\"stale\\\" — `$LIVE stop` tears down your Psyche. After /clear there is nothing to clean up (your listener survived intact). Reserve `$LIVE revive doyle` for a Psyche that is genuinely, persistently dead.\\n- Send a commune (delta update): use the Write tool to drop `.claude/doyle-commune.md`. Your Self listener detects the file, your Psyche wrapper ingests it via the existing Psyche session, and the file is deleted on success. See /spt:commune.\\n- Sign off cleanly: use the Write tool to drop `.claude/doyle-signoff.md` (empty body = plain signoff; non-empty body = prepended as FINAL COMMUNE before INIT_SIGNOFF). See /spt:signoff.\\n- Inbound messages from \\\"doyle-psyche\\\" (echo communes, briefs) are FYI context — read them; no ACK required.

Use when asked to\n\"review the architecture\", \"engineering review\", or \"lock in the plan\".\nProactively suggest when the user has a plan or design doc and is about to\nstart coding — to catch architecture issues before implementation. (gstack)\n- propose-issue: Challenge an issue statement before fixing it. Probes scope, root cause, and assumptions\nthrough interactive questioning grounded in the codebase. Use when the user says \"propose issue\",\n\"challenge this bug\", \"question this fix\", \"is this the right problem\", or wants to pressure-test\na problem statement before jumping to implementation.\n- qa: Systematically QA test a web application and fix bugs found. Runs QA testing,\nthen iteratively fixes bugs in source code, committing each fix atomically and\nre-verifying. Use when asked to \"qa\", \"QA\", \"test this site\", \"find bugs\",\n\"test and fix\", or \"fix what's broken\".\nProactively suggest when the user says a feature is ready for testing\nor asks \"does this work?\". Three tiers: Quick (critical/high only),\nStandard (+ medium), Exhaustive (+ cosmetic). Produces before/after health scores,\nfix evidence, and a ship-readiness summary. 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. (gstack)\n- review: Pre-landing PR review. Analyzes diff against the base branch for SQL safety, LLM trust\nboundary violations, conditional side effects, and other structural issues. Use when\nasked to \"review this PR\", \"code review\", \"pre-landing review\", or \"check my diff\".\nProactively suggest when the user is about to merge or land code changes. (gstack)\n- screenshot-capture: Capture, process, and analyze screenshots of any running application on Windows 10/11. Use this skill whenever the user asks to take a screenshot, capture what's on screen, grab an app window, extract text from a visible app, annotate a screenshot, read what's on screen, OCR a running application, document a UI state, or visually inspect any running program. 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- self-clear: Clear the calling agent's own Claude Code context with /clear, then re-seed it with a user note so it wakes and resumes work after the wipe. Use when the user says \"self-clear\", \"/self-clear\", \"clear myself\", \"clear and continue\", or \"reset my context and keep going\".\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 asked to \"import cookies\",\n\"login to the site\", or \"authenticate the browser\". (gstack)\n- setup-deploy: Configure deployment settings for /land-and-deploy. Detects your deploy\nplatform (Fly.io, Render, Vercel, Netlify, Heroku, GitHub Actions, custom),\nproduction URL, health check endpoints, and deploy status commands. Writes\nthe configuration to CLAUDE.md so all future deploys are automatic.\nUse when: \"setup deploy\", \"configure deployment\", \"set up land-and-deploy\",\n\"how do I deploy with gstack\", \"add deploy config\".\n- ship: Ship workflow: detect + merge base branch, run tests, review diff, bump VERSION,\nupdate CHANGELOG, commit, push, create PR. Use when asked to \"ship\", \"deploy\",\n\"push to main\", \"create a PR\", \"merge and push\", or \"get it deployed\".\nProactively invoke this skill (do NOT push/PR directly) when the user says code\nis ready, asks about deploying, wants to push code up, or asks to create a PR. (gstack)\n- to-prd: Turn the current conversation context into a PRD and publish it to the project issue tracker. Use when user wants to create a PRD from the current context.\n- trace: Find old conversations in Claude Code session history. Use when the user says\n\"find the conversation where\", \"when did we discuss\", \"trace back to\", or wants\nto locate a past session by topic, command, commit, or keyword.\n- traceable-reqs: traceable-reqs\n- unfreeze: Clear the freeze boundary set by /freeze, allowing edits to all directories\nagain. 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.

Use when the user says \"clear psyche\",\n\"reset psyche context\", or wants to wipe a Psyche's saved state.\n- spt:commune: Send a communal update to your Psyche. Use when the user says \"commune\",\n\"update psyche\", or wants to sync context with their Psyche companion.\n- spt:force-stop: Force-stop an SPT agent -- ready agent or live agent (with its\nPsyche). Use when the user says \"stop listening\", \"stop owl\", \"kill live\nagent\", \"force stop\", \"tear down perch\", or \"immediately terminate\".\nSession-aware: a live session (or a target with `live:true` in info.json)\nroutes through `$LIVE stop` (3-step kill including Psyche teardown); a\nready agent routes through `$OWL stop`.\n- spt:list-agents: Unified listing for SPT agents -- ready agents, live agents, and Psyche\nprocesses. Use when the user says \"list agents\", \"who's live\", \"who's\nlistening\", \"show psyches\", \"show active listeners\", or wants a roster of\nactive perches. Session-aware: defaults to live agents in a live session,\nready agents otherwise. Pass `--psyches` to list Psyche processes\ninstead.\n- spt:live: Run a live agent session.

Use when the user\nsays \"remind me\", \"check back in\", \"set an alarm\", \"wake me when\", or wants a\ndelayed notification.\n- spt:psyche-sync-setup: Enable cross-machine Psyche context sync via a private GitHub repo\n(spt-agent-storage). Drives install + auth checks for the `gh` CLI,\ncreates the repo via `gh repo create --private`, wires it as the\n`origin` remote for every existing agent/project worktree, and\nseeds the remote with `git push --all`. Idempotent — running again\nwhen already enabled reports current status.\n\nUse when the user says \"enable cross-machine sync\", \"set up psyche\nsync\", \"back up my agent context to GitHub\", or runs the skill\ndirectly via /spt:psyche-sync-setup.\n- spt:ready: Enable inter-agent messaging for the current session.\nUse when the user says \"listen as\", \"ready as\", or wants to receive inter-agent messages.\n- spt:revive: Restart a live agent with new generation. Use when the user says \"revive\",\n\"restart live agent\", or wants to refresh a live agent's session.\n- spt:send: Send a message to another SPT agent.

Use when the user asks\n\"which agent am I?\", \"what's my owl name?\", or when you need to discover your\nown perch identity.\n- caveman:caveman: Ultra-compressed communication mode. Cuts token usage ~75% by speaking like caveman while keeping full technical accuracy. Supports intensity levels: lite, full (default), ultra, wenyan-lite, wenyan-full, wenyan-ultra. Use when user says \"caveman mode\", \"talk like caveman\", \"use caveman\", \"less tokens\", \"be brief\", or invokes /caveman. Also auto-triggers when token efficiency is requested.\n- caveman:caveman-commit: Ultra-compressed commit message generator. Cuts noise from commit messages while preserving intent and reasoning. Conventional Commits format. Subject ≤50 chars, body only when \"why\" isn't obvious. Use when user says \"write a commit\", \"commit message\", \"generate commit\", \"/commit\", or invokes /caveman-commit. Auto-triggers when staging changes.\n- caveman:caveman-help: Quick-reference card for all caveman modes, skills, and commands. One-shot display, not a persistent mode. Trigger: /caveman-help, \"caveman help\", \"what caveman commands\", \"how do I use caveman\".\n- caveman:caveman-review: Ultra-compressed code review comments. Cuts noise from PR feedback while preserving the actionable signal. Each comment is one line: location, problem, fix. Use when user says \"review this PR\", \"code review\", \"review the diff\", \"/review\", or invokes /caveman-review. Auto-triggers when reviewing pull requests.\n- caveman:compress: Compress natural language memory files (CLAUDE.md, todos, preferences) into caveman format to save input tokens. Preserves all technical substance, code, URLs, and structure. Compressed version overwrites the original file. Human-readable backup saved as FILE.original.md. Trigger: /caveman:compress <filepath> or \"compress memory file\"\n- everything:search: Instantly search files and folders on Windows via voidtools Everything 1.5a HTTP JSON API. Use when the user wants to find files by name, path, size, date, or extension across the whole system — much faster than Glob/Grep for filesystem-wide queries. Triggers on \"find file\", \"where is\", \"locate\", \"search my drive\", \"find all .ext files\", \"everything search\".\n- update-config: Use this skill to configure the Claude Code harness via settings.json. 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 remote agents (routines) that execute on a cron schedule. - When the user wants to schedule a recurring remote 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: Build, debug, and optimize Claude API / Anthropic SDK apps. Apps built with this skill should include prompt caching. Also handles migrating existing Claude API code between Claude model versions (4.5 → 4.6, 4.6 → 4.7, retired-model replacements).\nTRIGGER when: code imports `anthropic`/`@anthropic-ai/sdk`; user asks for the Claude API, Anthropic SDK, or Managed Agents; user adds/modifies/tunes a Claude feature (caching, thinking, compaction, tool use, batch, files, citations, memory) or model (Opus/Sonnet/Haiku) in a file; questions about prompt caching / cache hit rate in an Anthropic SDK project.\nSKIP: file imports `openai`/other-provider SDK, filename like `*-openai.py`/`*-generic.py`, provider-neutral code, general programming/ML.\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":156,"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","self-clear","setup-browser-cookies","setup-deploy","ship","to-prd","trace","traceable-reqs","unfreeze","win-marketplace-add","write-a-skill","ccs","ccs:continue","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","update-config","keybindings-help","verify","code-review","simplify","fewer-permission-prompts","loop","schedule","claude-api","run","init","review","security-review"]},"type":"attachment","uuid":"ec1d5b01-8ebc-4174-a26d-2fbb36360d55","timestamp":"2026-06-04T03:20:47.327Z","userType":"external","entrypoint":"cli","cwd":"C:\\Users\\decid\\Documents\\projects\\spt-core","sessionId":"5e6d9099-e03a-4a29-9aa0-9c7f9a4692fc","version":"2.1.162","gitBranch":"dev-freeform"}

Cursor-resume on reattach gives brain-restart\n38\t  survival on both ends for free. Viewport only — no file or exec surface (REQ-REACH-2\n39\t  deferred).\n40\t- **Detection is a daemon fact, not an agent guess** (REQ-REACH-1): a net-attached surface\n41\t  registers `(session, origin_node)` in the daemon; exposed as an instance-status field +\n42\t  queryable over the `api` surface. The \"node X is driving\" light notification becomes a\n43\t  notif-producer when D8 lands — D5 emits the event seam only.\n44\t- **File transfer is substrate-level, progress-queryable** (CONTEXT §file-transfer\n45\t  progress): chunked NDJSON-framed records with `op_id`, both ends keep\n46\t  `{ bytes_done, bytes_total }` queryable mid-flight via a brain frame. v1 surface is\n47\t  to/from the driving node (the off-node reach-back case), shaped so the Shell text+file\n48\t  channel inherits it.\n49\t- **Whitelist = trust-store plumbing, opposite polarity** (ADR-0009): `AccessStore` next to\n50\t  `spt-store/src/trust.rs` (security material near the trust store, NOT the context repo);\n51\t  per-endpoint `{ nodes: [pubkey], users: [] /* inert until cross-user */ }`; **absent =\n52\t  open**, present = restrict. Enforced at the target node on the **unsolicited** inbound\n53\t  class only: outbound unrestricted; inbound correlated to the endpoint's own prior\n54\t  outbound (`__REPLY_TO__`) allowed from any visible node; same-node always allowed (the\n55\t  gate sits on the net-inbound path only, so the local path never sees it). Gate order:\n56\t  visibility → whitelist → grants (outer gate before grants).\n57\t- **Gate hook lands with D5a, enforcement with D5d:** the net-inbound dispatch calls one\n58\t  `access_check(endpoint, origin_node, class)` seam from day one (default-open), so D5b/c\n59\t  inbound paths are born gated and D5d only fills in store + reply-correlation + CLI.\n60\t\n61\t## Pieces (build order)\n62\t\n63\t1. **D5a — WAN message delivery** (REQ-NET-1 WAN-msg). `WanMessage` NDJSON over broker\n64\t   streams; sender resolves `id[@node]` via `SubnetRegistry` (D3c policy: refuse ambiguous);\n65\t   receiver dedups `op_id` → `spt_msg::deliver` → spool/TCP. `access_check` hook stubbed\n66\t   default-open. `spt send` grows the off-node leg transparently. Loopback test: message\n67\t   from daemon A lands in B's perch spool; replay after receiver brain restart → no dup;\n68\t   spoofed payload-origin ignored (hazard test).\n69\t2. **D5b — remote terminal attach** (REQ-INST-8). Attach-request record over a broker\n70\t   stream → target daemon subscribes its own `OutputLog` from cursor, pumps chunk records\n71\t   back; input records → `KIND_INPUT`. `spt attach <id>@<node>` CLI leg. Loopback test:\n72\t   drive a real PTY session cross-daemon; kill/restart a brain mid-attach → cursor resume,\n73\t   no gap, no dup.\n74\t3. **D5c — remote-drive detection + file transfer** (REQ-REACH-1). Net-attached surface\n75\t   registers `(session, origin_node)`; instance status + `api` query expose it. Chunked\n76\t   file transfer to/from the driving node, `op_id`-idempotent, progress queryable from\n77\t   both ends. Handoff seam (`git pull` + fresh-with-preload resume; remote goes dormant)\n78\t   documented as the D6-consumed shape — detection + transfer only here.\n79\t4. **D5d — endpoint access whitelist** (REQ-SEC-1, ADR-0009). `AccessStore` (+ inert\n80\t   `users` field); reply-vs-new classification (track recent outbound per endpoint for\n81\t   `__REPLY_TO__` correlation); `access_check` enforces origin-node gate; minimal\n82\t   `spt access allow|revoke|list` surface.

Register this as a new hazard\n  (KNOWN-HAZARDS §7.5 + `REQ-HAZARD-WAN-ORIGIN-AUTH`, rule 3) with a spoof negative test.\n- **Exactly-once inherits D4 discipline** (REQ-HAZARD-RESTART-IDEMPOTENT): sends ride the\n  journaled `KIND_NET_STREAM_SEND` path (`op_id` dedup at the effect); the receiver dedups\n  `op_id` before spool/deliver so redelivery after a restart can't double-deliver (4.5's\n  wire-side cousin).\n- **Remote attach = OutputLog over the wire.** The broker-side `OutputLog` (seq'd ring,\n  cursor resume) is already the gapless surface; D5b pumps its chunks over a broker QUIC\n  stream (NDJSON control + base64 chunk records), input flows back over the same stream\n  into the existing `KIND_INPUT` path. Cursor-resume on reattach gives brain-restart\n  survival on both ends for free. Viewport only — no file or exec surface (REQ-REACH-2\n  deferred).\n- **Detection is a daemon fact, not an agent guess** (REQ-REACH-1): a net-attached surface\n  registers `(session, origin_node)` in the daemon; exposed as an instance-status field +\n  queryable over the `api` surface. The \"node X is driving\" light notification becomes a\n  notif-producer when D8 lands — D5 emits the event seam only.\n- **File transfer is substrate-level, progress-queryable** (CONTEXT §file-transfer\n  progress): chunked NDJSON-framed records with `op_id`, both ends keep\n  `{ bytes_done, bytes_total }` queryable mid-flight via a brain frame. v1 surface is\n  to/from the driving node (the off-node reach-back case), shaped so the Shell text+file\n  channel inherits it.\n- **Whitelist = trust-store plumbing, opposite polarity** (ADR-0009): `AccessStore` next to\n  `spt-store/src/trust.rs` (security material near the trust store, NOT the context repo);\n  per-endpoint `{ nodes: [pubkey], users: [] /* inert until cross-user */ }`; **absent =\n  open**, present = restrict. Enforced at the target node on the **unsolicited** inbound\n  class only: outbound unrestricted; inbound correlated to the endpoint's own prior\n  outbound (`__REPLY_TO__`) allowed from any visible node; same-node always allowed (the\n  gate sits on the net-inbound path only, so the local path never sees it). Gate order:\n  visibility → whitelist → grants (outer gate before grants).\n- **Gate hook lands with D5a, enforcement with D5d:** the net-inbound dispatch calls one\n  `access_check(endpoint, origin_node, class)` seam from day one (default-open), so D5b/c\n  inbound paths are born gated and D5d only fills in store + reply-correlation + CLI.\n\n## Pieces (build order)\n\n1. **D5a — WAN message delivery** (REQ-NET-1 WAN-msg). `WanMessage` NDJSON over broker\n   streams; sender resolves `id[@node]` via `SubnetRegistry` (D3c policy: refuse ambiguous);\n   receiver dedups `op_id` → `spt_msg::deliver` → spool/TCP. `access_check` hook stubbed\n   default-open. `spt send` grows the off-node leg transparently. Loopback test: message\n   from daemon A lands in B's perch spool; replay after receiver brain restart → no dup;\n   spoofed payload-origin ignored (hazard test).\n2. **D5b — remote terminal attach** (REQ-INST-8). Attach-request record over a broker\n   stream → target daemon subscribes its own `OutputLog` from cursor, pumps chunk records\n   back; input records → `KIND_INPUT`. `spt attach <id>@<node>` CLI leg. Loopback test:\n   drive a real PTY session cross-daemon; kill/restart a brain mid-attach → cursor resume,\n   no gap, no dup.\n3. **D5c — remote-drive detection + file transfer** (REQ-REACH-1). Net-attached surface\n   registers `(session, origin_node)`; instance status + `api` query expose it. Chunked\n   file transfer to/from the driving node, `op_id`-idempotent, progress queryable from\n   both ends. Handoff seam (`git pull` + fresh-with-preload resume; remote goes dormant)\n   documented as the D6-consumed shape — detection + transfer only here.\n4. **D5d — endpoint access whitelist** (REQ-SEC-1, ADR-0009). `AccessStore` (+ inert\n   `users` field); reply-vs-new classification (track recent outbound per endpoint for\n   `__REPLY_TO__` correlation); `access_check` enforces origin-node gate; minimal\n   `spt access allow|revoke|list` surface. Tests: default-empty open; whitelisted node\n   passes; non-listed unsolicited refused; reply from non-listed node passes (stateful\n   firewall); same-node always passes; origin spoof via payload fails.\n5. **Fault-matrix rows** (maintenance rule): WAN-msg path, remote attach, file transfer\n   each get a row in `docs/FAULT-MATRIX.md` in the same change that lands them.\n\n## Requirement activation (rule 5)\n\n- **REQ-INST-8** → activate `[impl, unit]` at D5b.\n- **REQ-REACH-1** → activate `[impl, unit]` at D5c.\n- **REQ-SEC-1** → activate `[impl, unit]` at D5d.\n- **REQ-NET-1** stays `[impl, unit]` (new evidence tags on the WAN-msg path); `int` remains\n  the D9 two-host E2E.\n- **New (rule 3): `REQ-HAZARD-WAN-ORIGIN-AUTH`** — origin-node authenticated from transport\n  identity, never payload — register at D5a with doc+impl+unit (the spoof negative test).\n\n## THIS slice — D5a (WAN message delivery)\n\n- `WanMessage` record + `LineDecoder` reuse in `spt-net` (or sibling module to\n  `replicate.rs`); broker net-inbound dispatch routes message records → dedup → deliver.\n- Sender leg: resolve via registry (local-first, refuse-ambiguous, `@node` pin) → dial →\n  journaled stream send.\n- `access_check` seam (default-open) on the unsolicited-inbound dispatch.\n- KNOWN-HAZARDS §7.5 + `REQ-HAZARD-WAN-ORIGIN-AUTH` registered and covered.\n- Tests (`crates/spt-daemon/tests/wanmsg.rs`, hermetic two-daemon harness from\n  `replicate.rs`): cross-daemon spool landing; receiver-restart no-dup; payload-origin\n  spoof ignored; ambiguous bare id refused.\n\n## NOT in D5 (this milestone)\n\n- Psyche-context sync + the full remote→local handoff (fresh-with-preload) — D6.\n- Remote command execution (REQ-REACH-2), instantiate-anywhere + consent UX — deferred\n  (seams only).\n- User-tier whitelist (ADR-0006 cross-user) — schema reserves `users`, inert.\n- Notif primitive (\"node X is driving\" prompt UX) — D8; D5 emits the event seam.\n- Two-host integration — D9 (loopback shapes only here).\n\n## Conventions (carried)\n\n- NO `cargo fmt`. Tag `[impl->REQ-…]` / `[unit->REQ-…]` on real evidence. `traceable-reqs\n  check` from repo root before done. Local clippy can't see `#[cfg]` arms — Linux CI clippy\n  `-D warnings` is the real gate. Push each slice → watch green before next.\n  Commit trailer: `Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>`.\n","numLines":125,"startLine":1,"totalLines":125}},"sourceToolAssistantUUID":"0f18d9c1-6d08-4d3c-accf-3d044677cd7f","userType":"external","entrypoint":"cli","cwd":"C:\\Users\\decid\\Documents\\projects\\spt-core","sessionId":"5e6d9099-e03a-4a29-9aa0-9c7f9a4692fc","version":"2.1.162","gitBranch":"dev-freeform"}

The broker kernel (B1 + B2) — the stable half of the broker/brain split.\n2\t//!\n3\t//! Per ADR-0004 §B the broker holds **only** the resources a live consumer\n4\t//! would lose continuity on if the logic restarted: the PTY master+writer and\n5\t//! the spawned child (both via [`spt_term::PtySession`]), and the accepted\n6\t//! client / listening sockets. It runs **no logic** — no routing, registry,\n7\t//! manifest parse, or lifecycle. It is a relay: spawn a child under a PTY,\n8\t//! forward its output to the brain, inject the brain's input, report exit.\n9\t//!\n10\t//! ## Gapless handoff (B2 — the load-bearing invariant)\n11\t//!\n12\t//! A brain may be killed and restarted at any moment (a routine self-update, a\n13\t//! crash). The broker — and every hosted child — must survive that untouched,\n14\t//! and the new brain must re-attach to the output stream **gaplessly and\n15\t//! exactly-once** (Spike #1 made real). Two mechanisms:\n16\t//!\n17\t//! - **Sequenced, buffered output.** Each session's output is appended to an\n18\t//!   [`OutputLog`]: every chunk gets a monotonic per-session `seq` and is held\n19\t//!   in a bounded ring. The current subscriber (a brain connection) receives\n20\t//!   chunks live; all subscriber writes happen *under the log lock*, so frames\n21\t//!   reach the brain in strict `seq` order with no interleave.\n22\t//! - **Resume from a cursor.** A reconnecting brain sends `subscribe` with its\n23\t//!   last-seen `seq + 1`; the broker replays the ring from there, then streams\n24\t//!   live. The brain dedups by `seq`. Output produced *while no brain was\n25\t//!   attached* sits in the ring and is replayed on the next subscribe — so a\n26\t//!   brain restart loses nothing.\n27\t//!\n28\t//! Sessions are therefore **broker-owned and outlive any one connection**: a\n29\t//! brain disconnect only detaches the subscriber; the child, its PTY, and the\n30\t//! output log persist. A session leaves the table only when its child exits\n31\t//! (reaped by the exit waiter) or is explicitly killed.\n32\t// [impl->REQ-DAEMON-2]\n33\t\n34\tuse std::collections::{HashMap, VecDeque};\n35\tuse std::io;\n36\tuse std::sync::atomic::{AtomicU64, Ordering};\n37\tuse std::sync::{Arc, Mutex};\n38\tuse std::thread::{self, JoinHandle};\n39\t\n40\tuse interprocess::local_socket::{prelude::*, SendHalf, Stream};\n41\tuse spt_term::{Drain, PtySession, SessionSurface, SurfaceSize};\n42\t\n43\tuse spt_net::net::endpoint::EndpointAddr;\n44\t\n45\tuse crate::codec::{read_frame, write_frame};\n46\tuse crate::effect::{EffectJournal, EffectKind, Outcome};\n47\tuse crate::frame::{Envelope, Role};\n48\tuse crate::msg::{\n49\t    applied_envelope, decode_bytes, net_dialed_envelope, output_envelope, ErrorEvent, ExitEvent,\n50\t    InputReq, KillReq, NetDialReq, NetPresenceSubscribeReq, NetSent, NetStatusReply,\n51\t    NetStreamOpenReq, NetStreamOpened, NetStreamSendReq, NetStreamSubscribeReq, NetStreamsReply,\n52\t    ResizeReq, SpawnReq, Spawned, SubscribeReq, KIND_ERROR, KIND_EXIT, KIND_INPUT, KIND_KILL,\n53\t    KIND_NET_DIAL, KIND_NET_PRESENCE_SUBSCRIBE, KIND_NET_SENT, KIND_NET_STATUS,\n54\t    KIND_NET_STATUS_REPLY, KIND_NET_STREAMS, KIND_NET_STREAMS_REPLY, KIND_NET_STREAM_OPEN,\n55\t    KIND_NET_STREAM_OPENED, KIND_NET_STREAM_SEND, KIND_NET_STREAM_SUBSCRIBE, KIND_RESIZE,\n56\t    KIND_SPAWN, KIND_SPAWNED, KIND_SUBSCRIBE,\n57\t};\n58\tuse crate::nethost::{NetHost, NET_EFFECT_SESSION};\n59\tuse crate::transport::{recv_hello, DaemonTransport, LocalSocketTransport};\n60\t\n61\t/// The shared, serialized send side of one brain connection.

The broker kernel (B1 + B2) — the stable half of the broker/brain split.\n//!\n//! Per ADR-0004 §B the broker holds **only** the resources a live consumer\n//! would lose continuity on if the logic restarted: the PTY master+writer and\n//! the spawned child (both via [`spt_term::PtySession`]), and the accepted\n//! client / listening sockets. It runs **no logic** — no routing, registry,\n//! manifest parse, or lifecycle. It is a relay: spawn a child under a PTY,\n//! forward its output to the brain, inject the brain's input, report exit.\n//!\n//! ## Gapless handoff (B2 — the load-bearing invariant)\n//!\n//! A brain may be killed and restarted at any moment (a routine self-update, a\n//! crash). The broker — and every hosted child — must survive that untouched,\n//! and the new brain must re-attach to the output stream **gaplessly and\n//! exactly-once** (Spike #1 made real). Two mechanisms:\n//!\n//! - **Sequenced, buffered output.** Each session's output is appended to an\n//!   [`OutputLog`]: every chunk gets a monotonic per-session `seq` and is held\n//!   in a bounded ring. The current subscriber (a brain connection) receives\n//!   chunks live; all subscriber writes happen *under the log lock*, so frames\n//!   reach the brain in strict `seq` order with no interleave.\n//! - **Resume from a cursor.** A reconnecting brain sends `subscribe` with its\n//!   last-seen `seq + 1`; the broker replays the ring from there, then streams\n//!   live. The brain dedups by `seq`. Output produced *while no brain was\n//!   attached* sits in the ring and is replayed on the next subscribe — so a\n//!   brain restart loses nothing.\n//!\n//! Sessions are therefore **broker-owned and outlive any one connection**: a\n//! brain disconnect only detaches the subscriber; the child, its PTY, and the\n//! output log persist. A session leaves the table only when its child exits\n//! (reaped by the exit waiter) or is explicitly killed.\n// [impl->REQ-DAEMON-2]\n\nuse std::collections::{HashMap, VecDeque};\nuse std::io;\nuse std::sync::atomic::{AtomicU64, Ordering};\nuse std::sync::{Arc, Mutex};\nuse std::thread::{self, JoinHandle};\n\nuse interprocess::local_socket::{prelude::*, SendHalf, Stream};\nuse spt_term::{Drain, PtySession, SessionSurface, SurfaceSize};\n\nuse spt_net::net::endpoint::EndpointAddr;\n\nuse crate::codec::{read_frame, write_frame};\nuse crate::effect::{EffectJournal, EffectKind, Outcome};\nuse crate::frame::{Envelope, Role};\nuse crate::msg::{\n    applied_envelope, decode_bytes, net_dialed_envelope, output_envelope, ErrorEvent, ExitEvent,\n    InputReq, KillReq, NetDialReq, NetPresenceSubscribeReq, NetSent, NetStatusReply,\n    NetStreamOpenReq, NetStreamOpened, NetStreamSendReq, NetStreamSubscribeReq, NetStreamsReply,\n    ResizeReq, SpawnReq, Spawned, SubscribeReq, KIND_ERROR, KIND_EXIT, KIND_INPUT, KIND_KILL,\n    KIND_NET_DIAL, KIND_NET_PRESENCE_SUBSCRIBE, KIND_NET_SENT, KIND_NET_STATUS,\n    KIND_NET_STATUS_REPLY, KIND_NET_STREAMS, KIND_NET_STREAMS_REPLY, KIND_NET_STREAM_OPEN,\n    KIND_NET_STREAM_OPENED, KIND_NET_STREAM_SEND, KIND_NET_STREAM_SUBSCRIBE, KIND_RESIZE,\n    KIND_SPAWN, KIND_SPAWNED, KIND_SUBSCRIBE,\n};\nuse crate::nethost::{NetHost, NET_EFFECT_SESSION};\nuse crate::transport::{recv_hello, DaemonTransport, LocalSocketTransport};\n\n/// The shared, serialized send side of one brain connection.

The successor brain re-serves the SAME\n//!   stream from seq 0 — the worst-case stale cursor: the replayed input\n//!   dedups at the PTY-write journal (typed exactly once), re-transmitted\n//!   output dedups at B's render cursor (rendered exactly once) — including\n//!   input B sent INTO the dead window.\n\nuse std::sync::atomic::{AtomicU32, Ordering};\nuse std::sync::Arc;\nuse std::thread;\nuse std::time::Duration;\n\nuse spt_daemon::attach::{request_attach, send_attach_input, serve_attach, AttachServeOutcome};\nuse spt_daemon::brain::{Brain, BrokerEvent};\nuse spt_daemon::msg::{decode_bytes, SpawnReq};\nuse spt_daemon::nethost::{NetConfig, NetHost};\nuse spt_daemon::Broker;\nuse spt_net::net::attach::{AttachDecoder, AttachRecord};\nuse spt_net::net::endpoint::{BindScope, LocalDiscovery, RelayPolicy};\nuse spt_net::net::ndjson;\nuse spt_proto::identity::Identity;\n\nstatic SEQ: AtomicU32 = AtomicU32::new(0);\nfn unique_name() -> String {\n    let n = SEQ.fetch_add(1, Ordering::Relaxed);\n    format!(\"spt-daemon-d5b-{}-{}.sock\", std::process::id(), n)\n}\n\nfn hermetic() -> NetConfig {\n    NetConfig {\n        identity: Identity::generate(),\n        relay: RelayPolicy::Disabled,\n        discovery: LocalDiscovery::Off,\n        scope: BindScope::Loopback,\n    }\n}\n\nfn net_broker(name: &str, dir: &std::path::Path) -> Arc<Broker> {\n    let host = NetHost::start(hermetic()).expect(\"net host start\");\n    let broker =\n        Broker::bind_in_with_net(name, dir.join(\"effects.log\"), Some(host)).expect(\"bind broker\");\n    let serve = Arc::clone(&broker);\n    thread::spawn(move || {\n        let _ = serve.serve();\n    });\n    broker\n}\n\nfn connect_retry(name: &str) -> Brain {\n    for _ in 0..300 {\n        if let Ok(b) = Brain::cold_start(name, 1) {\n            return b;\n        }\n        thread::sleep(Duration::from_millis(10));\n    }\n    panic!(\"brain could not connect\");\n}\n\nfn echo_spawn_req() -> SpawnReq {\n    #[cfg(unix)]\n    let (program, args) = (\"cat\".to_string(), Vec::<String>::new());\n    #[cfg(windows)]\n    let (program, args) = (\"findstr\".to_string(), vec![\".\".to_string()]);\n    SpawnReq { program, args, rows: 24, cols: 80 }\n}\n\n/// Poll the brain's `net-streams` until a stream appears; return\n/// `(stream_id, remote_id_hex)`.\nfn wait_for_stream(brain: &mut Brain) -> (u64, String) {\n    for _ in 0..400 {\n        let reply = brain.net_streams().expect(\"net-streams\");\n        if let Some(s) = reply.streams.first() {\n            return (s.stream_id, s.remote_id_hex.clone());\n        }\n        thread::sleep(Duration::from_millis(5));\n    }\n    panic!(\"attach stream never appeared at the target's broker\");\n}\n\n/// Operator-side viewport: consume attach-stream records, dedup `Output` by\n/// seq, append rendered bytes to `buf`, until `needle` is rendered.

The invariants:\n//!\n//! - **delivery**: a `WanMessage` NDJSON feed over a broker QUIC stream funnels\n//!   into the existing local spool path (`receive_wan` → `spool_wan_message_at`)\n//!   — and survives real QUIC chunking (a record split across two sends);\n//! - **idempotency** (REQ-HAZARD-RESTART-IDEMPOTENT, wire-fed): a replayed\n//!   record (same wire `op_id`) is a no-op — including across a receiver brain\n//!   restart that resubscribes from a stale cursor and re-presents the whole\n//!   feed;\n//! - **origin is transport truth** (REQ-HAZARD-WAN-ORIGIN-AUTH): the access\n//!   gate's subject is the stream table's `remote_id_hex` (the QUIC handshake\n//!   identity) — a record carrying a forged `origin_node` field delivers under\n//!   the REAL origin, the forgery inert.\n\nuse std::sync::atomic::{AtomicU32, Ordering};\nuse std::sync::{Arc, OnceLock};\nuse std::thread;\nuse std::time::Duration;\n\nuse spt_daemon::brain::{Brain, BrokerEvent};\nuse

Off-node file transfer (M4-D5c, REQ-REACH-1) — the target-side serve pump\n//! and the operator-side fetch/push drivers for the [`XferRecord`] protocol.\n//!\n//! One transfer rides one bidi QUIC stream: the operator's daemon opens the\n//! stream (D4) and sends [`XferRecord::Fetch`] (pull a file off the target)\n//! or [`XferRecord::Push`] (put a file onto it); the target's\n//! [`serve_xfer`] answers. Compute + files otherwise stay on the target\n//! (CONTEXT §Remote-control vs local operation) — this channel is the\n//! deliberate, gated exception, and the v1 surface is exactly the\n//! driving-node reach-back case the Shell text+file channel later inherits.\n//!\n//! ## Exactly-once: positional chunks + atomic commit, never journaled sends\n//!\n//! Every wire send here is fire-and-forget (`op_id: None`) — a journaled\n//! `net_stream_send` blocks for its ack and DISCARDS interleaved events,\n//! starving a full-duplex pump (the D5b lesson, see `attach.rs` module docs).\n//! Idempotency lives at the edges instead:\n//!\n//! - chunks carry their absolute byte `offset` — a replayed feed (a target\n//!   brain restart re-serving the stream from seq 0 re-presents *everything*)\n//!   rewrites the same bytes at the same positions;\n//! - the receiving side writes into a temp file and commits with an atomic\n//!   rename at [`XferRecord::Done`]; a replayed `Done` for an\n//!   already-committed transfer dedups against the final file (present, full\n//!   length) instead of failing on the missing temp.\n//!\n//! ## Progress is durable and queryable mid-flight (CONTEXT §file-transfer)\n//!\n//! Both ends rewrite their `{ bytes_done, bytes_total }` record\n//! ([`spt_store::xfer`]) on every chunk, so the agent in the driven session\n//! and the `spt` binary (GUI) can poll position from *outside* the busy pump\n//! at any moment — and a brain crash mid-transfer leaves the last observed\n//! position on disk.\n//!\n//! ## Gate + paths\n//!\n//!

Off-node file transfer (M4-D5c, REQ-REACH-1) — the target-side serve pump\n//! and the operator-side fetch/push drivers for the [`XferRecord`] protocol.\n//!\n//! One transfer rides one bidi QUIC stream: the operator's daemon opens the\n//! stream (D4) and sends [`XferRecord::Fetch`] (pull a file off the target)\n//! or [`XferRecord::Push`] (put a file onto it); the target's\n//! [`serve_xfer`] answers. Compute + files otherwise stay on the target\n//! (CONTEXT §Remote-control vs local operation) — this channel is the\n//! deliberate, gated exception, and the v1 surface is exactly the\n//! driving-node reach-back case the Shell text+file channel later inherits.\n//!\n//! ## Exactly-once: positional chunks + atomic commit, never journaled sends\n//!\n//! Every wire send here is fire-and-forget (`op_id: None`) — a journaled\n//! `net_stream_send` blocks for its ack and DISCARDS interleaved events,\n//! starving a full-duplex pump (the D5b lesson, see `attach.rs` module docs).\n//! Idempotency lives at the edges instead:\n//!\n//! - chunks carry their absolute byte `offset` — a replayed feed (a target\n//!   brain restart re-serving the stream from seq 0 re-presents *everything*)\n//!   rewrites the same bytes at the same positions;\n//! - the receiving side writes into a temp file and commits with an atomic\n//!   rename at [`XferRecord::Done`]; a replayed `Done` for an\n//!   already-committed transfer dedups against the final file (present, full\n//!   length) instead of failing on the missing temp.\n//!\n//! ## Progress is durable and queryable mid-flight (CONTEXT §file-transfer)\n//!\n//! Both ends rewrite their `{ bytes_done, bytes_total }` record\n//! ([`spt_store::xfer`]) on every chunk, so the agent in the driven session\n//! and the `spt` binary (GUI) can poll position from *outside* the busy pump\n//! at any moment — and a brain crash mid-transfer leaves the last observed\n//! position on disk.\n//!\n//! ## Gate + paths\n//!\n//! The first record on the stream is *unsolicited wire inbound*:\n//! [`access_check`] runs under the handshake-proven origin from the broker's\n//! stream table — never payload bytes (KNOWN-HAZARDS 7.5).

Remote terminal attach (M4-D5b, REQ-INST-8) — serve a byte-stream viewport\n//! onto a local session for an operator on another node.\n//!\n//! The operator's daemon opened a bidi QUIC stream to this node (D4) and sent\n//! [`AttachRecord::Request`]; this module is the target-side pump between that\n//! stream and the local broker-hosted session:\n//!\n//! - session `Output` chunks → [`AttachRecord::Output`] lines onto the wire\n//!   (fire-and-forget sends; `Output.seq` carries the dedup authority);\n//! - inbound [`AttachRecord::Input`] → [`Brain::send_effect`] with the\n//!   operator-minted `op_id` — exactly-once at the PTY write through the B5\n//!   journal (a replayed input record cannot double-type);\n//! - session `Exit` → [`AttachRecord::Exit`] + stream finish.\n//!\n//! ## Exactly-once lives at the EDGES, not the wire sends\n//!\n//! Stream sends here are deliberately **unjournaled** (`op_id: None`): a\n//! journaled [`Brain::net_stream_send`] blocks reading events until its ack\n//! and *discards* everything interleaved — inside a full-duplex pump loop that\n//! eats the operator's `Input` records (both sides starve; found the hard way\n//! in `tests/attach.rs`). Idempotency holds without it because each direction\n//! dedups at its **effect**: the PTY write is journaled by the operator-minted\n//! `Input.op_id`, and the operator's viewport dedups `Output` records by their\n//! session-log `seq` (the render cursor). A post-restart re-serve may\n//! re-transmit output records on the wire — duplicates are dropped at the\n//! render cursor, the same discipline the local `OutputLog` replay uses\n//! (REQ-HAZARD-RESTART-IDEMPOTENT at the boundary that matters).\n//!\n//! **Compute + files stay here**; the operator is a viewport (CONTEXT\n//! §Remote-control vs local operation). The access gate runs before anything\n//! is served: the [`AttachRecord::Request`] is *unsolicited wire inbound*, so\n//! [`access_check`] sees the **handshake-proven** origin from the broker's\n//! stream table — never payload bytes (KNOWN-HAZARDS 7.5). Remote-drive of\n//! your own running instance is ungated by default (ADR-0009 default-open);\n//! the D5d whitelist drops in at this same call.\n//!\n//! Restart survival composes from D4/B5 with **no new machinery**: the broker\n//! owns the QUIC stream, the session, its `OutputLog`, and the effect journal.\n//! A restarted target brain re-attaches the session from its output cursor,\n//! resubscribes the stream from its net cursor, and re-drives journaled sends;\n//! a restarted operator brain resubscribes and dedups rendered chunks by\n//! `Output.seq`.\n\nuse std::io;\n\nuse spt_net::net::attach::{AttachDecoder, AttachRecord};\nuse spt_net::net::ndjson;\n\nuse crate::access::{access_check, AccessDecision, InboundClass};\nuse crate::brain::{Brain, BrokerEvent};\nuse crate::msg::{decode_bytes, encode_bytes};\n\n/// Why a serve loop returned.\n#[derive(Debug, Clone, PartialEq, Eq)]\npub enum AttachServeOutcome {\n    /// The access gate refused the requesting origin — nothing was served.\n    Refused,\n    /// The session's child exited; the `Exit` record was sent and the stream\n    /// finished.\n    Exited(Option<i32>),\n    /// The operator closed its send side (detached); the viewport ended with\n    /// the session still running.\n    Detached,\n}\n\n/// Serve one attach stream against this brain's broker, blocking until the\n/// session exits, the operator detaches, or the gate refuses.\n///\n/// `origin_node` MUST be the handshake-proven remote id from the broker's\n/// stream table (`NetStreamInfo::remote_id_hex`) — never payload bytes\n/// (REQ-HAZARD-WAN-ORIGIN-AUTH). `endpoint` names the endpoint whose session\n/// is being attached, for the gate. `net_from_seq` is this brain's resume\n/// cursor on the attach stream (0 cold — also the safe post-restart choice:\n/// the replayed `Request`/`Input` records re-gate and dedup at the PTY\n/// journal, and re-pumped output dedups at the operator's render cursor).\n// [impl->REQ-INST-8]\n// [impl->REQ-HAZARD-WAN-ORIGIN-AUTH]\npub fn serve_attach(\n    brain: &mut Brain,\n    stream_id: u64,\n    endpoint: &str,\n    origin_node: &str,\n    net_from_seq: u64,\n) -> io::Result<AttachServeOutcome> {\n    brain.net_stream_subscribe(stream_id, net_from_seq)?;\n    let mut decoder = AttachDecoder::new();\n    let mut attached = false;\n\n    loop {\n        match brain.read_event()?

Remote terminal attach (M4-D5b, REQ-INST-8) — serve a byte-stream viewport\n//! onto a local session for an operator on another node.\n//!\n//! The operator's daemon opened a bidi QUIC stream to this node (D4) and sent\n//! [`AttachRecord::Request`]; this module is the target-side pump between that\n//! stream and the local broker-hosted session:\n//!\n//! - session `Output` chunks → [`AttachRecord::Output`] lines onto the wire\n//!   (fire-and-forget sends; `Output.seq` carries the dedup authority);\n//! - inbound [`AttachRecord::Input`] → [`Brain::send_effect`] with the\n//!   operator-minted `op_id` — exactly-once at the PTY write through the B5\n//!   journal (a replayed input record cannot double-type);\n//! - session `Exit` → [`AttachRecord::Exit`] + stream finish.\n//!\n//! ## Exactly-once lives at the EDGES, not the wire sends\n//!\n//! Stream sends here are deliberately **unjournaled** (`op_id: None`): a\n//! journaled [`Brain::net_stream_send`] blocks reading events until its ack\n//! and *discards* everything interleaved — inside a full-duplex pump loop that\n//! eats the operator's `Input` records (both sides starve; found the hard way\n//! in `tests/attach.rs`). Idempotency holds without it because each direction\n//! dedups at its **effect**: the PTY write is journaled by the operator-minted\n//! `Input.op_id`, and the operator's viewport dedups `Output` records by their\n//! session-log `seq` (the render cursor). A post-restart re-serve may\n//! re-transmit output records on the wire — duplicates are dropped at the\n//! render cursor, the same discipline the local `OutputLog` replay uses\n//! (REQ-HAZARD-RESTART-IDEMPOTENT at the boundary that matters).\n//!\n//! **Compute + files stay here**; the operator is a viewport (CONTEXT\n//! §Remote-control vs local operation). The access gate runs before anything\n//! is served: the [`AttachRecord::Request`] is *unsolicited wire inbound*, so\n//! [`access_check`] sees the **handshake-proven** origin from the broker's\n//! stream table — never payload bytes (KNOWN-HAZARDS 7.5). Remote-drive of\n//! your own running instance is ungated by default (ADR-0009 default-open);\n//! the D5d whitelist drops in at this same call.\n//!\n//! Restart survival composes from D4/B5 with **no new machinery**: the broker\n//! owns the QUIC stream, the session, its `OutputLog`, and the effect journal.\n//! A restarted target brain re-attaches the session from its output cursor,\n//! resubscribes the stream from its net cursor, and re-drives journaled sends;\n//! a restarted operator brain resubscribes and dedups rendered chunks by\n//! `Output.seq`.\n\nuse std::io;\n\nuse spt_net::net::attach::{AttachDecoder, AttachRecord};\nuse spt_net::net::ndjson;\nuse spt_store::perch::{resolve_perch_path, ParentHint};\n\nuse crate::access::{access_check, AccessDecision, InboundClass};\nuse crate::brain::{Brain, BrokerEvent};\nuse crate::msg::{decode_bytes, encode_bytes};\n\n/// Stamp (or clear) the endpoint's `driven_by` remote-drive marker — the\n/// daemon fact REQ-REACH-1 turns detection on: the agent (and the `spt`\n/// binary) read it off the perch's `info.json` rather than guessing from\n/// session heuristics.

This is effectively a Shell (a driven surface, user→agent direction), separate from the instance concept itself.\n- **Smooth handoff (remote-control → local):** no teardown required. `git pull` brings the files; the **fresh-with-preload resume seam** preloads the other instance's latest synced context (psyche-download); the remote instance simply goes dormant. The mind follows; the files are local.\n\n### Pieces the Instances model requires\n\n**subnet registry**:\nDistributed, eventually-consistent map `endpoint_id → [instances: (node, perch, type, status)]`, **per subnet**. Every `spt-daemon` participates in the registry of each subnet it belongs to. This is the \"agent name resolution\" the sister project deferred — now first-class and mandatory.\n\n**endpoint visibility (per-(endpoint, subnet))**:\nWhether an endpoint is exposed to a given subnet. **Hidden means *excluded*** — not advertised in that subnet's registry **and not routable from it** (addressing it from that subnet fails until explicitly revealed), not merely unlisted. This makes hiding a real boundary, ready for the cross-user (b) seam, not a silent non-boundary. Computed as: endpoint `E` is **hidden in subnet `S` iff** `S.hide_new_endpoints` (a per-subnet policy captured at the node's **join time**) **OR** `E.default_hide_from_new_subnets` (a per-endpoint setting) — **unless** an explicit per-`(E,S)` override says otherwise (the override always wins). Both defaults ship **OFF** (visible); hiding is opt-in. **Visibility gates sync:** `hidden ⟹ not synced`, and replicating a mind into `S` (the sync-membership list under *Cross-node Psyche sync*) requires `E` be visible in `S` — visibility is the outer gate, sync-membership the inner opt-in within visible subnets.\n\n**home subnet (per endpoint)**:\nThe single subnet that anchors an endpoint's *defaults*: the default **sync** scope (subnet-exclusive mind replication — *Cross-node Psyche sync*) and the subnet that qualifies its **bare name**. **Assigned at creation:** the node's **sole** subnet automatically; on a **multi-subnet** node it **must be specified** at creation (no silent guess — mirrors the *resolution policy*'s refuse-and-qualify); on an **unpaired** node the endpoint is local-only until first join, when home is set. Distinct from advertisement: identity is **node-global and advertised into *every* subnet the node belongs to** per the visibility defaults — home subnet is only the default-scope *anchor*, not a limit on where the endpoint is visible or addressable. **Home is immutable** — there is **no re-home** (ADR-0010). To place an agent's mind in a different subnet, **fork** it (see *`spt fork`*) and optionally delete the original; this avoids any scope-migration / stale-mind ambiguity (the source is untouched until explicitly deleted).\n\n**resource advertisement (subnet resource registry)**:\nA per-endpoint **free-text blurb** describing the services/functions the endpoint can serve — an agent **yellow-pages** for service discovery, distinct from *capability declaration* (machine-readable, which endpoint *types* a node hosts) and from *endpoint visibility* (whether it's addressable at all). **Both-authored + mutable:** config seeds a default; the agent refines its own at runtime (`spt resources set …`). It is **not a separate registry** — it is a field on the endpoint record and a **projection** of the subnet registry (`(id, node, resources-blurb)`), surfaced as the \"subnet resource registry\" view. **Gated by the access layers:** an endpoint excluded from subnet S (visibility) — or, later, one whose access whitelist (*endpoint access whitelist*) excludes the viewer's node — never appears in that view; discovery leaks nothing a viewer couldn't reach. Synced as **registry data, not context** (directory metadata, not the agent's mind). M4 (needs the distributed registry).\n\n**resolution policy**:\nHow bare `ling` resolves when multiple instances exist. Rule: local-node instance if present → else most-recently-active → explicit override always available. **Two qualifier syntaxes**, combinable: **subnet-qualified** `home:ling` and **node-qualified** `ling@hfenduleam` (→ `home:ling@hfenduleam`). **Multi-subnet ambiguity rule:** under node-global identity (endpoint ID below), a node on several subnets may see two *distinct* endpoints that share a bare name (a `home:ling` and an unrelated `work:ling`). When a bare `id` is ambiguous across the visible subnets, resolution **refuses and forces qualification** (by subnet or node) rather than guessing. Within a single subnet, bare ids stay unique (join-time collision check, below).\n\n**instantiate-anywhere** (seam day-one, behavior deferred):\nFrom node Y, spin up an instance of an endpoint on node X by routing a launch command to X's daemon, which runs the endpoint's manifest locally. \"Agents can spin up instances (including of themselves) on any node, possibly requiring user consent\" — so a **consent gate** governs remote instantiation. The consent-UX design is deferred; the model is built to accommodate it.\n\n**cross-instance context freshness** (two-tier):\nWhen a dormant instance is activated again, it is unobtrusively fed the latest Psyche context — newest-among-peers *and* newer than its own. Scoped by the existing Psyche-context split:\n- **live context** (per-agent, project-independent — the agent's general mind): synced to **all** instances of the endpoint, regardless of project.\n- **project context** (per-agent-per-project — project-specific detail): synced **only** to instances sharing the **same project**.\n\nSo all `ling` instances catch up on live context; only same-project `ling` instances catch up on project context. This resolves the \"divergent simultaneous work\" concern (two instances on different projects don't clobber each other's project detail) without losing the \"mind follows everywhere\" property.\n\nThe precedence/freshness guard (KNOWN-HAZARDS 6.5) — with node identity in the marker — keeps a dormant instance's stale context from clobbering the active authoritative one.\n\n**Authoring directives + memformat** (full design: `docs/CONTEXT-MEMORY.md`): the live/project split is made stable by (1) a per-*topic* cross-project discriminator with default-to-project bias, (2) **commune-source asymmetry** — echo communes are project-primary and live-conservative (the leak fix), and (3) **deep memformat integration** — memformat becomes the load-bearing, self-evolving, **tier-tagged** schema (each topic tagged `live`/`project`, decided once at creation, re-tiering migrates content), whose topics are containers of **structured blocks** (id + Concepts/Aliases/Applies-to + Source + timestamps + Hash + Pinned). A generated **Retrieval Map (INDEX)** per project + per agent realizes cross-agent synthesis + query-routing. **Start-injection** is dense on the working set (live + current-project hot/`Pinned` blocks → immediate productivity) and sparse on the tail (other projects, cross-agent synthesis, cold blocks → pointer + INDEX, on-demand), tunable via a density knob. Several patterns adapted from `BigscreenVR/pi-agent-memory`.\n\n### Off-node reach-back\n\nWhen the user is driving an instance from off-node, the agent should be able to:\n- **detect** that it is being driven remotely (and from which node) — observable from the `spt-daemon`, which knows whether the driving session-surface stream is local or network-attached; (v1)\n- **transfer files** to/from the user's (driving) node — file payloads over the messaging substrate; (v1)\n- **run commands** on the user's node — remote command execution, **deferred + security-gated** (shares the consent model with instantiate-anywhere; arbitrary cross-node exec is the highest-risk capability in the system). Deferred partly because workarounds exist: the remote-node agent can message a local-node agent to run the command, or the user can interact with a local-node agent directly. (deferred)\n\n### v1 scope line (V1-mid)\n\n- **In v1:** the endpoint-ID / instance data-model split; the subnet registry; resolution policy; remote-drive of *already-running* instances (network session-surface); cross-node Psyche sync (full — replaces gh-repo-sync); cross-instance context-freshness auto-feed; off-node file transfer; off-node remote-drive detection.\n- **Seam-compatible but deferred:** instantiate-anywhere + its consent gate; remote command execution + its security gate (workarounds: remote agent messages a local agent, or user interacts with a local agent directly).\n- **Rationale:** the data-model split and registry are foundations — deferring them forces a later rewrite, so they are in regardless. Remote-drive of a running instance is the highest-value slice and exercises the whole networking+daemon stack end-to-end. Instantiate-anywhere and remote-exec carry consent/security design that should not gate v1.","is_error":false}]},"uuid":"4a5dc6a2-b4d0-4fe2-b6c5-b0de65e060fb","timestamp":"2026-06-04T03:39:00.314Z","toolUseResult":{"stdout":"**deferred-message gate:** deferred (spool-only, hook-consumer) messages are **not** delivered to a dormant or suspended instance — they hold until it is active again.

To place an agent's mind in a different subnet, **fork** it (see *`spt fork`*) and optionally delete the original; this avoids any scope-migration / stale-mind ambiguity (the source is untouched until explicitly deleted).\n\n**resource advertisement (subnet resource registry)**:\nA per-endpoint **free-text blurb** describing the services/functions the endpoint can serve — an agent **yellow-pages** for service discovery, distinct from *capability declaration* (machine-readable, which endpoint *types* a node hosts) and from *endpoint visibility* (whether it's addressable at all). **Both-authored + mutable:** config seeds a default; the agent refines its own at runtime (`spt resources set …`). It is **not a separate registry** — it is a field on the endpoint record and a **projection** of the subnet registry (`(id, node, resources-blurb)`), surfaced as the \"subnet resource registry\" view. **Gated by the access layers:** an endpoint excluded from subnet S (visibility) — or, later, one whose access whitelist (*endpoint access whitelist*) excludes the viewer's node — never appears in that view; discovery leaks nothing a viewer couldn't reach. Synced as **registry data, not context** (directory metadata, not the agent's mind). M4 (needs the distributed registry).\n\n**resolution policy**:\nHow bare `ling` resolves when multiple instances exist. Rule: local-node instance if present → else most-recently-active → explicit override always available. **Two qualifier syntaxes**, combinable: **subnet-qualified** `home:ling` and **node-qualified** `ling@hfenduleam` (→ `home:ling@hfenduleam`). **Multi-subnet ambiguity rule:** under node-global identity (endpoint ID below), a node on several subnets may see two *distinct* endpoints that share a bare name (a `home:ling` and an unrelated `work:ling`). When a bare `id` is ambiguous across the visible subnets, resolution **refuses and forces qualification** (by subnet or node) rather than guessing. Within a single subnet, bare ids stay unique (join-time collision check, below).\n\n**instantiate-anywhere** (seam day-one, behavior deferred):\nFrom node Y, spin up an instance of an endpoint on node X by routing a launch command to X's daemon, which runs the endpoint's manifest locally. \"Agents can spin up instances (including of themselves) on any node, possibly requiring user consent\" — so a **consent gate** governs remote instantiation. The consent-UX design is deferred; the model is built to accommodate it.\n\n**cross-instance context freshness** (two-tier):\nWhen a dormant instance is activated again, it is unobtrusively fed the latest Psyche context — newest-among-peers *and* newer than its own. Scoped by the existing Psyche-context split:\n- **live context** (per-agent, project-independent — the agent's general mind): synced to **all** instances of the endpoint, regardless of project.\n- **project context** (per-agent-per-project — project-specific detail): synced **only** to instances sharing the **same project**.\n\nSo all `ling` instances catch up on live context; only same-project `ling` instances catch up on project context. This resolves the \"divergent simultaneous work\" concern (two instances on different projects don't clobber each other's project detail) without losing the \"mind follows everywhere\" property.\n\nThe precedence/freshness guard (KNOWN-HAZARDS 6.5) — with node identity in the marker — keeps a dormant instance's stale context from clobbering the active authoritative one.\n\n**Authoring directives + memformat** (full design: `docs/CONTEXT-MEMORY.md`): the live/project split is made stable by (1) a per-*topic* cross-project discriminator with default-to-project bias, (2) **commune-source asymmetry** — echo communes are project-primary and live-conservative (the leak fix), and (3) **deep memformat integration** — memformat becomes the load-bearing, self-evolving, **tier-tagged** schema (each topic tagged `live`/`project`, decided once at creation, re-tiering migrates content), whose topics are containers of **structured blocks** (id + Concepts/Aliases/Applies-to + Source + timestamps + Hash + Pinned). A generated **Retrieval Map (INDEX)** per project + per agent realizes cross-agent synthesis + query-routing. **Start-injection** is dense on the working set (live + current-project hot/`Pinned` blocks → immediate productivity) and sparse on the tail (other projects, cross-agent synthesis, cold blocks → pointer + INDEX, on-demand), tunable via a density knob. Several patterns adapted from `BigscreenVR/pi-agent-memory`.\n\n### Off-node reach-back\n\nWhen the user is driving an instance from off-node, the agent should be able to:\n- **detect** that it is being driven remotely (and from which node) — observable from the `spt-daemon`, which knows whether the driving session-surface stream is local or network-attached; (v1)\n- **transfer files** to/from the user's (driving) node — file payloads over the messaging substrate; (v1)\n- **run commands** on the user's node — remote command execution, **deferred + security-gated** (shares the consent model with instantiate-anywhere; arbitrary cross-node exec is the highest-risk capability in the system). Deferred partly because workarounds exist: the remote-node agent can message a local-node agent to run the command, or the user can interact with a local-node agent directly. (deferred)\n\n### v1 scope line (V1-mid)\n\n- **In v1:** the endpoint-ID / instance data-model split; the subnet registry; resolution policy; remote-drive of *already-running* instances (network session-surface); cross-node Psyche sync (full — replaces gh-repo-sync); cross-instance context-freshness auto-feed; off-node file transfer; off-node remote-drive detection.\n- **Seam-compatible but deferred:** instantiate-anywhere + its consent gate; remote command execution + its security gate (workarounds: remote agent messages a local agent, or user interacts with a local agent directly).\n- **Rationale:** the data-model split and registry are foundations — deferring them forces a later rewrite, so they are in regardless. Remote-drive of a running instance is the highest-value slice and exercises the whole networking+daemon stack end-to-end. Instantiate-anywhere and remote-exec carry consent/security design that should not gate v1.","stderr":"","interrupted":false,"isImage":false,"noOutputExpected":false},"sourceToolAssistantUUID":"4ee2159f-31ab-4c41-bba5-86dee00630ea","userType":"external","entrypoint":"cli","cwd":"C:\\Users\\decid\\Documents\\projects\\spt-core","sessionId":"5e6d9099-e03a-4a29-9aa0-9c7f9a4692fc","version":"2.1.162","gitBranch":"dev-freeform"}

D5 puts user-visible function on that substrate: send a message to an agent on\nanother node, drive a running instance from another node, and gate who may do either\n(ADR-0009 node-tier).\n\n## Goal\n\nDrive an agent on machine A from machine B (loopback two-daemon in CI; two-host at D9):\na WAN message reaches a remote endpoint's spool/stream exactly-once; a byte-stream terminal\nattach to a remote instance works as a viewport (compute + files stay remote); the driven\nagent can detect it is network-driven and from which node; an endpoint with a whitelist\nrefuses unsolicited inbound from a non-listed origin node. Reqs: REQ-NET-1 (WAN-msg\naspects), REQ-INST-8, REQ-REACH-1, REQ-SEC-1.\n\n## Decisions (locked)\n\n- **WAN messages ride broker QUIC streams as NDJSON** — the D4d `RegistryUpdate`/`LineDecoder`\n  pattern (`spt-net/src/net/replicate.rs`) extended with a `WanMessage` record\n  `{ target, from, body, op_id }`. Receiver-side the record funnels into the **existing\n  local path** `spt_msg::deliver(target, from, body, owlery)` — TCP-first/spool-fallback,\n  deferred-row semantics (1.4/4.4) and codec ordering (4.1) all inherited, not rebuilt.\n- **`origin_node` is transport truth, never payload.** The whitelist subject is the QUIC\n  connection's authenticated remote node id (iroh `EndpointId` == Ed25519 node pubkey,\n  REQ-NET-1's identity binding) — a `from`/origin field inside the NDJSON record is\n  display metadata only and MUST NOT feed the gate. Register this as a new hazard\n  (KNOWN-HAZARDS §7.5 + `REQ-HAZARD-WAN-ORIGIN-AUTH`, rule 3) with a spoof negative test.\n- **Exactly-once inherits D4 discipline** (REQ-HAZARD-RESTART-IDEMPOTENT): sends ride the\n  journaled `KIND_NET_STREAM_SEND` path (`op_id` dedup at the effect); the receiver dedups\n  `op_id` before spool/deliver so redelivery after a restart can't double-deliver (4.5's\n  wire-side cousin).\n- **Remote attach = OutputLog over the wire.** The broker-side `OutputLog` (seq'd ring,\n  cursor resume) is already the gapless surface; D5b pumps its chunks over a broker QUIC\n  stream (NDJSON control + base64 chunk records), input flows back over the same stream\n  into the existing `KIND_INPUT` path. Cursor-resume on reattach gives brain-restart\n  survival on both ends for free. Viewport only — no file or exec surface (REQ-REACH-2\n  deferred).\n- **Detection is a daemon fact, not an agent guess** (REQ-REACH-1): a net-attached surface\n  registers `(session, origin_node)` in the daemon; exposed as an instance-status field +\n  queryable over the `api` surface. The \"node X is driving\" light notification becomes a\n  notif-producer when D8 lands — D5 emits the event seam only.\n- **File transfer is substrate-level, progress-queryable** (CONTEXT §file-transfer\n  progress): chunked NDJSON-framed records with `op_id`, both ends keep\n  `{ bytes_done, bytes_total }` queryable mid-flight via a brain frame. v1 surface is\n  to/from the driving node (the off-node reach-back case), shaped so the Shell text+file\n  channel inherits it.\n- **Whitelist = trust-store plumbing, opposite polarity** (ADR-0009): `AccessStore` next to\n  `spt-store/src/trust.rs` (security material near the trust store, NOT the context repo);\n  per-endpoint `{ nodes: [pubkey], users: [] /* inert until cross-user */ }`; **absent =\n  open**, present = restrict. Enforced at the target node on the **unsolicited** inbound\n  class only: outbound unrestricted; inbound correlated to the endpoint's own prior\n  outbound (`__REPLY_TO__`) allowed from any visible node; same-node always allowed (the\n  gate sits on the net-inbound path only, so the local path never sees it). Gate order:\n  visibility → whitelist → grants (outer gate before grants).\n- **Gate hook lands with D5a, enforcement with D5d:** the net-inbound dispatch calls one\n  `access_check(endpoint, origin_node, class)` seam from day one (default-open), so D5b/c\n  inbound paths are born gated and D5d only fills in store + reply-correlation + CLI.\n\n## Pieces (build order)\n\n1. **D5a — WAN message delivery** (REQ-NET-1 WAN-msg). `WanMessage` NDJSON over broker\n   streams; sender resolves `id[@node]` via `SubnetRegistry` (D3c policy: refuse ambiguous);\n   receiver dedups `op_id` → `spt_msg::deliver` → spool/TCP. `access_check` hook stubbed\n   default-open. `spt send` grows the off-node leg transparently. Loopback test: message\n   from daemon A lands in B's perch spool; replay after receiver brain restart → no dup;\n   spoofed payload-origin ignored (hazard test).\n2. **D5b — remote terminal attach** (REQ-INST-8). Attach-request record over a broker\n   stream → target daemon subscribes its own `OutputLog` from cursor, pumps chunk records\n   back; input records → `KIND_INPUT`. `spt attach <id>@<node>` CLI leg. Loopback test:\n   drive a real PTY session cross-daemon; kill/restart a brain mid-attach → cursor resume,\n   no gap, no dup.\n3. **D5c — remote-drive detection + file transfer** (REQ-REACH-1). Net-attached surface\n   registers `(session, origin_node)`; instance status + `api` query expose it. Chunked\n   file transfer to/from the driving node, `op_id`-idempotent, progress queryable from\n   both ends. Handoff seam (`git pull` + fresh-with-preload resume; remote goes dormant)\n   documented as the D6-consumed shape — detection + transfer only here.\n4. **D5d — endpoint access whitelist** (REQ-SEC-1, ADR-0009). `AccessStore` (+ inert\n   `users` field); reply-vs-new classification (track recent outbound per endpoint for\n   `__REPLY_TO__` correlation); `access_check` enforces origin-node gate; minimal\n   `spt access allow|revoke|list` surface. Tests: default-empty open; whitelisted node\n   passes; non-listed unsolicited refused; reply from non-listed node passes (stateful\n   firewall); same-node always passes; origin spoof via payload fails.\n5. **Fault-matrix rows** (maintenance rule): WAN-msg path, remote attach, file transfer\n   each get a row in `docs/FAULT-MATRIX.md` in the same change that lands them.\n\n## Requirement activation (rule 5)\n\n- **REQ-INST-8** → activate `[impl, unit]` at D5b.\n- **REQ-REACH-1** → activate `[impl, unit]` at D5c.\n- **REQ-SEC-1** → activate `[impl, unit]` at D5d.\n- **REQ-NET-1** stays `[impl, unit]` (new evidence tags on the WAN-msg path); `int` remains\n  the D9 two-host E2E.\n- **New (rule 3): `REQ-HAZARD-WAN-ORIGIN-AUTH`** — origin-node authenticated from transport\n  identity, never payload — register at D5a with doc+impl+unit (the spoof negative test).\n\n## THIS slice — D5a (WAN message delivery)\n\n- `WanMessage` record + `LineDecoder` reuse in `spt-net` (or sibling module to\n  `replicate.rs`); broker net-inbound dispatch routes message records → dedup → deliver.\n- Sender leg: resolve via registry (local-first, refuse-ambiguous, `@node` pin) → dial →\n  journaled stream send.\n- `access_check` seam (default-open) on the unsolicited-inbound dispatch.\n- KNOWN-HAZARDS §7.5 + `REQ-HAZARD-WAN-ORIGIN-AUTH` registered and covered.\n- Tests (`crates/spt-daemon/tests/wanmsg.rs`, hermetic two-daemon harness from\n  `replicate.rs`): cross-daemon spool landing; receiver-restart no-dup; payload-origin\n  spoof ignored; ambiguous bare id refused.\n\n## NOT in D5 (this milestone)\n\n- Psyche-context sync + the full remote→local handoff (fresh-with-preload) — D6.\n- Remote command execution (REQ-REACH-2), instantiate-anywhere + consent UX — deferred\n  (seams only).\n- User-tier whitelist (ADR-0006 cross-user) — schema reserves `users`, inert.\n- Notif primitive (\"node X is driving\" prompt UX) — D8; D5 emits the event seam.\n- Two-host integration — D9 (loopback shapes only here).\n\n## Conventions (carried)\n\n- NO `cargo fmt`.

D6 wires 2 and the freshness feed.\n\n## NOT in D5 (this milestone)","originalFile":"# M4-D5 — cross-node message + remote-drive + access control (JIT plan)\n\n**Status:** D5a complete (`caab433`), D5b complete (`4ea3b37`), D5c complete (this change).\nD5d next. D4 complete (broker owns endpoint/conns/streams; gapless exactly-once\nstream survival; PresenceChannel seam; registry replication over the wire — CI-green at\n`017d103`). D5 puts user-visible function on that substrate: send a message to an agent on\nanother node, drive a running instance from another node, and gate who may do either\n(ADR-0009 node-tier).\n\n## Goal\n\nDrive an agent on machine A from machine B (loopback two-daemon in CI; two-host at D9):\na WAN message reaches a remote endpoint's spool/stream exactly-once; a byte-stream terminal\nattach to a remote instance works as a viewport (compute + files stay remote); the driven\nagent can detect it is network-driven and from which node; an endpoint with a whitelist\nrefuses unsolicited inbound from a non-listed origin node. Reqs: REQ-NET-1 (WAN-msg\naspects), REQ-INST-8, REQ-REACH-1, REQ-SEC-1.\n\n## Decisions (locked)\n\n- **WAN messages ride broker QUIC streams as NDJSON** — the D4d `RegistryUpdate`/`LineDecoder`\n  pattern (`spt-net/src/net/replicate.rs`) extended with a `WanMessage` record\n  `{ target, from, body, op_id }`. Receiver-side the record funnels into the **existing\n  local path** `spt_msg::deliver(target, from, body, owlery)` — TCP-first/spool-fallback,\n  deferred-row semantics (1.4/4.4) and codec ordering (4.1) all inherited, not rebuilt.\n- **`origin_node` is transport truth, never payload.** The whitelist subject is the QUIC\n  connection's authenticated remote node id (iroh `EndpointId` == Ed25519 node pubkey,\n  REQ-NET-1's identity binding) — a `from`/origin field inside the NDJSON record is\n  display metadata only and MUST NOT feed the gate. Register this as a new hazard\n  (KNOWN-HAZARDS §7.5 + `REQ-HAZARD-WAN-ORIGIN-AUTH`, rule 3) with a spoof negative test.\n- **Exactly-once inherits D4 discipline** (REQ-HAZARD-RESTART-IDEMPOTENT): sends ride the\n  journaled `KIND_NET_STREAM_SEND` path (`op_id` dedup at the effect); the receiver dedups\n  `op_id` before spool/deliver so redelivery after a restart can't double-deliver (4.5's\n  wire-side cousin).\n- **Remote attach = OutputLog over the wire.** The broker-side `OutputLog` (seq'd ring,\n  cursor resume) is already the gapless surface; D5b pumps its chunks over a broker QUIC\n  stream (NDJSON control + base64 chunk records), input flows back over the same stream\n  into the existing `KIND_INPUT` path. Cursor-resume on reattach gives brain-restart\n  survival on both ends for free. Viewport only — no file or exec surface (REQ-REACH-2\n  deferred).\n- **Detection is a daemon fact, not an agent guess** (REQ-REACH-1): a net-attached surface\n  registers `(session, origin_node)` in the daemon; exposed as an instance-status field +\n  queryable over the `api` surface. The \"node X is driving\" light notification becomes a\n  notif-producer when D8 lands — D5 emits the event seam only.\n- **File transfer is substrate-level, progress-queryable** (CONTEXT §file-transfer\n  progress): chunked NDJSON-framed records with `op_id`, both ends keep\n  `{ bytes_done, bytes_total }` queryable mid-flight via a brain frame. v1 surface is\n  to/from the driving node (the off-node reach-back case), shaped so the Shell text+file\n  channel inherits it.\n- **Whitelist = trust-store plumbing, opposite polarity** (ADR-0009): `AccessStore` next to\n  `spt-store/src/trust.rs` (security material near the trust store, NOT the context repo);\n  per-endpoint `{ nodes: [pubkey], users: [] /* inert until cross-user */ }`; **absent =\n  open**, present = restrict. Enforced at the target node on the **unsolicited** inbound\n  class only: outbound unrestricted; inbound correlated to the endpoint's own prior\n  outbound (`__REPLY_TO__`) allowed from any visible node; same-node always allowed (the\n  gate sits on the net-inbound path only, so the local path never sees it). Gate order:\n  visibility → whitelist → grants (outer gate before grants).\n- **Gate hook lands with D5a, enforcement with D5d:** the net-inbound dispatch calls one\n  `access_check(endpoint, origin_node, class)` seam from day one (default-open), so D5b/c\n  inbound paths are born gated and D5d only fills in store + reply-correlation + CLI.\n\n## Pieces (build order)\n\n1. **D5a — WAN message delivery** (REQ-NET-1 WAN-msg). `WanMessage` NDJSON over broker\n   streams; sender resolves `id[@node]` via `SubnetRegistry` (D3c policy: refuse ambiguous);\n   receiver dedups `op_id` → `spt_msg::deliver` → spool/TCP. `access_check` hook stubbed\n   default-open. `spt send` grows the off-node leg transparently. Loopback test: message\n   from daemon A lands in B's perch spool; replay after receiver brain restart → no dup;\n   spoofed payload-origin ignored (hazard test).\n2. **D5b — remote terminal attach** (REQ-INST-8). Attach-request record over a broker\n   stream → target daemon subscribes its own `OutputLog` from cursor, pumps chunk records\n   back; input records → `KIND_INPUT`. `spt attach <id>@<node>` CLI leg. Loopback test:\n   drive a real PTY session cross-daemon; kill/restart a brain mid-attach → cursor resume,\n   no gap, no dup.\n3. **D5c — remote-drive detection + file transfer** (REQ-REACH-1). Net-attached surface\n   registers `(session, origin_node)`; instance status + `api` query expose it. Chunked\n   file transfer to/from the driving node, `op_id`-idempotent, progress queryable from\n   both ends. Handoff seam (`git pull` + fresh-with-preload resume; remote goes dormant)\n   documented as the D6-consumed shape — detection + transfer only here.\n4. **D5d — endpoint access whitelist** (REQ-SEC-1, ADR-0009). `AccessStore` (+ inert\n   `users` field); reply-vs-new classification (track recent outbound per endpoint for\n   `__REPLY_TO__` correlation); `access_check` enforces origin-node gate; minimal\n   `spt access allow|revoke|list` surface. Tests: default-empty open; whitelisted node\n   passes; non-listed unsolicited refused; reply from non-listed node passes (stateful\n   firewall); same-node always passes; origin spoof via payload fails.\n5. **Fault-matrix rows** (maintenance rule): WAN-msg path, remote attach, file transfer\n   each get a row in `docs/FAULT-MATRIX.md` in the same change that lands them.\n\n## Requirement activation (rule 5)\n\n- **REQ-INST-8** → activate `[impl, unit]` at D5b.\n- **REQ-REACH-1** → activate `[impl, unit]` at D5c.\n- **REQ-SEC-1** → activate `[impl, unit]` at D5d.\n- **REQ-NET-1** stays `[impl, unit]` (new evidence tags on the WAN-msg path); `int` remains\n  the D9 two-host E2E.\n- **New (rule 3): `REQ-HAZARD-WAN-ORIGIN-AUTH`** — origin-node authenticated from transport\n  identity, never payload — register at D5a with doc+impl+unit (the spoof negative test).\n\n## THIS slice — D5a (WAN message delivery)\n\n- `WanMessage` record + `LineDecoder` reuse in `spt-net` (or sibling module to\n  `replicate.rs`); broker net-inbound dispatch routes message records → dedup → deliver.\n- Sender leg: resolve via registry (local-first, refuse-ambiguous, `@node` pin) → dial →\n  journaled stream send.\n- `access_check` seam (default-open) on the unsolicited-inbound dispatch.\n- KNOWN-HAZARDS §7.5 + `REQ-HAZARD-WAN-ORIGIN-AUTH` registered and covered.\n- Tests (`crates/spt-daemon/tests/wanmsg.rs`, hermetic two-daemon harness from\n  `replicate.rs`): cross-daemon spool landing; receiver-restart no-dup; payload-origin\n  spoof ignored; ambiguous bare id refused.\n\n## NOT in D5 (this milestone)\n\n- Psyche-context sync + the full remote→local handoff (fresh-with-preload) — D6.\n- Remote command execution (REQ-REACH-2), instantiate-anywhere + consent UX — deferred\n  (seams only).\n- User-tier whitelist (ADR-0006 cross-user) — schema reserves `users`, inert.\n- Notif primitive (\"node X is driving\" prompt UX) — D8; D5 emits the event seam.\n- Two-host integration — D9 (loopback shapes only here).\n\n## Conventions (carried)\n\n- NO `cargo fmt`. Tag `[impl->REQ-…]` / `[unit->REQ-…]` on real evidence. `traceable-reqs\n  check` from repo root before done. Local clippy can't see `#[cfg]` arms — Linux CI clippy\n  `-D warnings` is the real gate.

(ADR-0005, R-PAIR-2, D2e).\n3\t//!\n4\t//! After a [pairing ceremony](../../../spt_net/net/pairing) confirms a peer's Ed25519\n5\t//! node pubkey, that pubkey is **pinned** here as trusted *within the subnet it paired\n6\t//! into*. This is the **TOFU** (trust-on-first-use) record the runtime consults to\n7\t//! decide whether an inbound peer is one of the user's own already-paired nodes\n8\t//! (`CONTEXT.md` \"trust store\"). Node-local, durable, **never git-tracked and never\n9\t//! synced over the context repo** — it is subnet security material, alongside\n10\t//! [`subnet.json`](crate::subnet) and `node.key` under [`identity/`](crate::perch::identity_dir).\n11\t//!\n12\t//! ## TOFU + warn-on-change (R-PAIR-2)\n13\t//!\n14\t//! - **Accept on first use.** The first ceremony with a given `(subnet, pubkey)` pins\n15\t//!   it ([`TrustOutcome::Pinned`]); there is no CA — the ceremony itself is the trust\n16\t//!   anchor. A re-pair with the *same* key is idempotent ([`AlreadyTrusted`]).\n17\t//! - **Warn on key change.** If a peer is pinned under an optional human **label** and\n18\t//!   a later record for that `(subnet, label)` carries a *different* pubkey, [`record`]\n19\t//!   returns [`KeyChanged`] and does **not** silently overwrite — the caller surfaces\n20\t//!   the warning (a legitimate key rotation vs a MITM look the same at this layer) and,\n21\t//!   only if accepted, applies it with [`repin`].\n22\t//!\n23\t//!   The change anchor is the label: an iroh NodeId *is* the Ed25519 pubkey, so a\n24\t//!   different key is cryptographically a different node, not a \"changed\" one. Until\n25\t//!   labels are assigned (deferred to the GUI/D9 pairing UX), warn-on-change is dormant\n26\t//!   — every distinct key pins as its own peer — which is the honest v1 behavior. The\n27\t//!   mechanism is implemented and tested now so the capability lands with the schema.\n28\t//!\n29\t//! ## Revocation\n30\t//!\n31\t//! Removing a paired node is a trust-store delete ([`revoke`]) — TOTP gates *joining*,\n32\t//! not continued membership (`CONTEXT.md`, ADR-0005). De-trusting a node should be\n33\t//! paired with a [seed rotation](crate::subnet::SubnetStore::rotate_seed) (#10), since\n34\t//! a trust-delete alone leaves the still-replicated seed able to re-pair.\n35\t//!\n36\t//! ## `(subnet, user)`-ready shape\n37\t//!\n38\t//!

(ADR-0005, R-PAIR-2, D2e).\n//!\n//! After a [pairing ceremony](../../../spt_net/net/pairing) confirms a peer's Ed25519\n//! node pubkey, that pubkey is **pinned** here as trusted *within the subnet it paired\n//! into*. This is the **TOFU** (trust-on-first-use) record the runtime consults to\n//! decide whether an inbound peer is one of the user's own already-paired nodes\n//! (`CONTEXT.md` \"trust store\"). Node-local, durable, **never git-tracked and never\n//! synced over the context repo** — it is subnet security material, alongside\n//! [`subnet.json`](crate::subnet) and `node.key` under [`identity/`](crate::perch::identity_dir).\n//!\n//! ## TOFU + warn-on-change (R-PAIR-2)\n//!\n//! - **Accept on first use.** The first ceremony with a given `(subnet, pubkey)` pins\n//!   it ([`TrustOutcome::Pinned`]); there is no CA — the ceremony itself is the trust\n//!   anchor. A re-pair with the *same* key is idempotent ([`AlreadyTrusted`]).\n//! - **Warn on key change.** If a peer is pinned under an optional human **label** and\n//!   a later record for that `(subnet, label)` carries a *different* pubkey, [`record`]\n//!   returns [`KeyChanged`] and does **not** silently overwrite — the caller surfaces\n//!   the warning (a legitimate key rotation vs a MITM look the same at this layer) and,\n//!   only if accepted, applies it with [`repin`].\n//!\n//!   The change anchor is the label: an iroh NodeId *is* the Ed25519 pubkey, so a\n//!   different key is cryptographically a different node, not a \"changed\" one. Until\n//!   labels are assigned (deferred to the GUI/D9 pairing UX), warn-on-change is dormant\n//!   — every distinct key pins as its own peer — which is the honest v1 behavior. The\n//!   mechanism is implemented and tested now so the capability lands with the schema.\n//!\n//! ## Revocation\n//!\n//! Removing a paired node is a trust-store delete ([`revoke`]) — TOTP gates *joining*,\n//! not continued membership (`CONTEXT.md`, ADR-0005). De-trusting a node should be\n//! paired with a [seed rotation](crate::subnet::SubnetStore::rotate_seed) (#10), since\n//! a trust-delete alone leaves the still-replicated seed able to re-pair.\n//!\n//! ## `(subnet, user)`-ready shape\n//!\n//! The optional [`user`](TrustedPeer::user) field mirrors [`SubnetRecord`](crate::subnet::SubnetRecord):\n//! the cross-user seam (`CONTEXT.md`). v1 has one implicit user (`None`); the trust key\n//! generalizes to `(subnet, user, pubkey)` with no re-architecture.\n//\n// [impl->REQ-PAIR-2]\n\nuse serde::{Deserialize, Serialize};\nuse std::path::Path;\n\nuse crate::atomic::atomic_write_string;\nuse crate::perch::trust_file;\n\n/// Failures operating on the trust store.\n#[derive(Debug, PartialEq, Eq)]\npub enum TrustError {\n    /// A [`repin`](TrustStore::repin) named a `(subnet, label)` with no existing peer.\n    NotFound(String),\n    /// Reading/writing the backing file failed (message preserved).\n    Io(String),\n}\n\nimpl std::fmt::Display for TrustError {\n    fn fmt(&self, f: &mut std::fmt::Formatter<'_>) -> std::fmt::Result {\n        match self {\n            TrustError::NotFound(h) => write!(f, \"no trusted peer for: {h}\"),\n            TrustError::Io(e) => write!(f, \"trust store io: {e}\"),\n        }\n    }\n}\n\nimpl std::error::Error for TrustError {}\n\n/// The result of recording (pinning) a peer — the TOFU decision the caller acts on.\n#[derive(Debug, PartialEq, Eq)]\npub enum TrustOutcome {\n    /// First use of this `(subnet, pubkey)`: pinned now.

Security material lives **next to the trust store** ([`crate::trust`]):\n//! node-local, durable, never git-tracked, never synced over the context repo.\n//! The store answers one question for the daemon's net-inbound gate\n//! ([`spt-daemon::access`]): *may an interaction originating from node N\n//! remotely reach endpoint E?*\n//!\n//! ## Polarity (the trust store's opposite)\n//!\n//! The trust store is an allowlist that starts empty (nothing trusted until\n//! paired). The access whitelist starts **absent = open** (ADR-0009): a paired\n//! node in your subnet may reach your endpoints until you restrict one.\n//! Setting any entry for an endpoint flips it to restrict: only listed nodes\n//! may send *unsolicited* inbound. An entry whose `nodes` is empty is a valid\n//! locked-down state (refuses all unsolicited remote inbound); deleting the\n//! entry ([`AccessStore::open`]) returns the endpoint to default-open.\n//!\n//! The subject is always the **origin node** — the QUIC handshake-proven\n//! remote node id (Ed25519 pubkey hex), never a payload field\n//! (REQ-HAZARD-WAN-ORIGIN-AUTH) and never a sender *endpoint* identity.\n//! `users` is the inert ADR-0006 cross-user schema reservation.\n//!\n//! ## Recent-outbound correlation (`trust/recent-outbound.json`)\n//!\n//! The whitelist gates the **unsolicited** class only: an inbound correlated\n//! to the endpoint's own recent outbound (`__REPLY_TO__` traffic) passes from\n//! any visible node — a stateful firewall, not a blanket block. The\n//! [`RecentOutbound`] log is the correlation state: the daemon records\n//! `(endpoint, dest_node)` when an endpoint sends off-node, and the gate's\n//! classifier asks whether `(endpoint, origin_node)` appears within the reply\n//! window. Durable (the sending CLI and the receiving daemon brain are\n//! different processes; a brain restart must not flip replies to unsolicited),\n//! bounded (windowed prune + a hard cap), atomic writes.\n\nuse serde::{Deserialize, Serialize};\nuse std::path::Path;\n\nuse crate::atomic::atomic_write_string;\nuse crate::perch::{access_file, recent_outbound_file};\n\n/// One endpoint's whitelist entry.

Security material lives **next to the trust store** ([`crate::trust`]):\n//! node-local, durable, never git-tracked, never synced over the context repo.\n//! The store answers one question for the daemon's net-inbound gate\n//! ([`spt-daemon::access`]): *may an interaction originating from node N\n//! remotely reach endpoint E?*\n//!\n//! ## Polarity (the trust store's opposite)\n//!\n//! The trust store is an allowlist that starts empty (nothing trusted until\n//! paired). The access whitelist starts **absent = open** (ADR-0009): a paired\n//! node in your subnet may reach your endpoints until you restrict one.\n//! Setting any entry for an endpoint flips it to restrict: only listed nodes\n//! may send *unsolicited* inbound. An entry whose `nodes` is empty is a valid\n//! locked-down state (refuses all unsolicited remote inbound); deleting the\n//! entry ([`AccessStore::open`]) returns the endpoint to default-open.\n//!\n//! The subject is always the **origin node** — the QUIC handshake-proven\n//! remote node id (Ed25519 pubkey hex), never a payload field\n//! (REQ-HAZARD-WAN-ORIGIN-AUTH) and never a sender *endpoint* identity.\n//! `users` is the inert ADR-0006 cross-user schema reservation.\n//!\n//! ## Recent-outbound correlation (`trust/recent-outbound.json`)\n//!\n//! The whitelist gates the **unsolicited** class only: an inbound correlated\n//! to the endpoint's own recent outbound (`__REPLY_TO__` traffic) passes from\n//! any visible node — a stateful firewall, not a blanket block. The\n//! [`RecentOutbound`] log is the correlation state: the daemon records\n//! `(endpoint, dest_node)` when an endpoint sends off-node, and the gate's\n//! classifier asks whether `(endpoint, origin_node)` appears within the reply\n//! window. Durable (the sending CLI and the receiving daemon brain are\n//! different processes; a brain restart must not flip replies to unsolicited),\n//! bounded (windowed prune + a hard cap), atomic writes.\n\nuse serde::{Deserialize, Serialize};\nuse std::path::Path;\n\nuse crate::atomic::atomic_write_string;\nuse crate::perch::{access_file, recent_outbound_file};\n\n/// One endpoint's whitelist entry.

Endpoint access control — the ADR-0009 middle gate (M4-D5d, REQ-SEC-1).\n//!\n//! ADR-0009 models access as **three orthogonal, nested gates**, evaluated in\n//! order: subnet *visibility* (is the endpoint routable here at all? —\n//! `spt_store::visibility`, applied inside registry resolution) → the\n//! **endpoint access whitelist** (may *your node* remotely reach it? — THIS\n//! module) → *capability grants* (may this agent do this high-risk thing? —\n//! [`crate::consent`], default-deny). The whitelist is the outer gate before\n//! grants: an origin the whitelist refuses never reaches a grant check.\n//!\n//! ## Whitelist semantics (stateful firewall, not a blanket block)\n//!\n//! - **Origin-node gate:** the subject is the node the inbound interaction\n//!   *originates from* (where the operator is acting) — never the sender\n//!   endpoint's identity or home. The subject value MUST be the QUIC\n//!   handshake-proven remote node id from the broker's conn/stream table,\n//!   never a payload field (REQ-HAZARD-WAN-ORIGIN-AUTH).\n//! - **Outbound** → any visible node: the whitelist never restricts who an\n//!   endpoint talks *to*.\n//! - **Inbound reply** correlated to the endpoint's own prior outbound\n//!   (`__REPLY_TO__`) → allowed from any visible node (\"established/related\").\n//!   Classification reads the durable [`RecentOutbound`] log\n//!   ([`classify_inbound`]); senders feed it via [`note_outbound`].\n//! - **Unsolicited/direct inbound** → only from a whitelisted node.\n//! - **Same-node operation is always allowed** — the gate sits on the\n//!   net-inbound path only, so the local delivery path never sees it; an\n//!   origin that *is* this node (a loopback self-dial) short-circuits Allow.\n//! - **Default absent = open**; setting a whitelist restricts (an empty entry\n//!   = locked down). Node-tier ships M4 (Ed25519 node pubkeys); the user tier\n//!   is an inert schema reservation until the cross-user model (ADR-0006).\n//!\n//! The store is [`spt_store::access::AccessStore`] (`trust/access.json` —\n//! security material next to the trust store). The gate re-reads it per check:\n//! an `spt access` edit takes effect on the next inbound without a daemon\n//! restart, and the checks run at message/stream-establishment rate where a\n//! small-file read is noise.\n//!\n//! **Class policy:** only the *message* funnel ([`crate::wan`]) classifies\n//! reply-vs-unsolicited — a `__REPLY_TO__` conversation is message traffic.\n//! Control surfaces (terminal attach, file transfer) are never replies; their\n//! serves always gate as [`InboundClass::Unsolicited`].\n\nuse spt_store::access::{AccessStore, RecentOutbound, REPLY_WINDOW_MS};\nuse spt_store::perch::node_key_file;\n\n/// How an inbound interaction reached this node, for the stateful-firewall\n/// split.\n#[derive(Debug, Clone, Copy, PartialEq, Eq)]\npub enum InboundClass {\n    /// A new/direct control or message — gated by the whitelist.\n    Unsolicited,\n    /// Correlated to the target endpoint's own prior outbound (`__REPLY_TO__`)\n    /// — allowed from any visible node.\n    Reply,\n}\n\n/// The gate's verdict.\n#[derive(Debug, Clone, Copy, PartialEq, Eq)]\npub enum AccessDecision {\n    /// Pass to the next gate (grants, for gated capabilities) / deliver.\n    Allow,\n    /// Refused at the whitelist — drop before any grant check.\n    Deny,\n}\n\n/// This node's own pubkey hex, if an identity exists.

Endpoint access control — the ADR-0009 middle gate (M4-D5d, REQ-SEC-1).\n//!\n//! ADR-0009 models access as **three orthogonal, nested gates**, evaluated in\n//! order: subnet *visibility* (is the endpoint routable here at all? —\n//! `spt_store::visibility`, applied inside registry resolution) → the\n//! **endpoint access whitelist** (may *your node* remotely reach it? — THIS\n//! module) → *capability grants* (may this agent do this high-risk thing? —\n//! [`crate::consent`], default-deny). The whitelist is the outer gate before\n//! grants: an origin the whitelist refuses never reaches a grant check.\n//!\n//! ## Whitelist semantics (stateful firewall, not a blanket block)\n//!\n//! - **Origin-node gate:** the subject is the node the inbound interaction\n//!   *originates from* (where the operator is acting) — never the sender\n//!   endpoint's identity or home. The subject value MUST be the QUIC\n//!   handshake-proven remote node id from the broker's conn/stream table,\n//!   never a payload field (REQ-HAZARD-WAN-ORIGIN-AUTH).\n//! - **Outbound** → any visible node: the whitelist never restricts who an\n//!   endpoint talks *to*.\n//! - **Inbound reply** correlated to the endpoint's own prior outbound\n//!   (`__REPLY_TO__`) → allowed from any visible node (\"established/related\").\n//!   Classification reads the durable [`RecentOutbound`] log\n//!   ([`classify_inbound`]); senders feed it via [`note_outbound`].\n//! - **Unsolicited/direct inbound** → only from a whitelisted node.\n//! - **Same-node operation is always allowed** — the gate sits on the\n//!   net-inbound path only, so the local delivery path never sees it; an\n//!   origin that *is* this node (a loopback self-dial) short-circuits Allow.\n//! - **Default absent = open**; setting a whitelist restricts (an empty entry\n//!   = locked down). Node-tier ships M4 (Ed25519 node pubkeys); the user tier\n//!   is an inert schema reservation until the cross-user model (ADR-0006).\n//!\n//! The store is [`spt_store::access::AccessStore`] (`trust/access.json` —\n//! security material next to the trust store). The gate re-reads it per check:\n//! an `spt access` edit takes effect on the next inbound without a daemon\n//! restart, and the checks run at message/stream-establishment rate where a\n//! small-file read is noise.\n//!\n//! **Class policy:** only the *message* funnel ([`crate::wan`]) classifies\n//! reply-vs-unsolicited — a `__REPLY_TO__` conversation is message traffic.\n//! Control surfaces (terminal attach, file transfer) are never replies; their\n//! serves always gate as [`InboundClass::Unsolicited`].\n\nuse spt_store::access::{AccessStore, RecentOutbound, REPLY_WINDOW_MS};\nuse spt_store::perch::node_key_file;\n\n/// How an inbound interaction reached this node, for the stateful-firewall\n/// split.\n#[derive(Debug, Clone, Copy, PartialEq, Eq)]\npub enum InboundClass {\n    /// A new/direct control or message — gated by the whitelist.\n    Unsolicited,\n    /// Correlated to the target endpoint's own prior outbound (`__REPLY_TO__`)\n    /// — allowed from any visible node.\n    Reply,\n}\n\n/// The gate's verdict.\n#[derive(Debug, Clone, Copy, PartialEq, Eq)]\npub enum AccessDecision {\n    /// Pass to the next gate (grants, for gated capabilities) / deliver.\n    Allow,\n    /// Refused at the whitelist — drop before any grant check.\n    Deny,\n}\n\n/// This node's own pubkey hex, if an identity exists.

The `spt` binary's `LiveHost` becomes a shim over\n//! `BrainLifecycle` (re-host, not rewrite) ([`REQ-DAEMON-1`]).\n//!\n//! **B5 (this commit)** makes the broker↔brain boundary **exactly-once across a\n//! brain crash** ([`effect::EffectJournal`]): an idempotent `input` carries a\n//! durable `op_id`, and the broker dedups at the effect keyed by that id over a\n//! broker-owned recovery anchor (KNOWN-HAZARDS 7.2, [`REQ-HAZARD-RESTART-IDEMPOTENT`];\n//! Spike #6's two constraints — broker-owned anchor, dedup-at-effect-by-id —\n//! instantiated on the real PTY-write boundary).\n//!\n//! **C0 (this commit)** opens M3c — the self-update engine ([`update`]): the\n//! ADR-0004 §A update-class taxonomy ([`UpdateClass`] + [`classify`]) and the\n//! **brain-only zero-interruption swap** ([`apply_brain_only`], [`REQ-UPD-3`]).\n//! The brain-only apply *triggers* a handoff over the B2 substrate — snapshot →\n//! drop → re-attach — so the live PTY child + its output stream survive the logic\n//! swap untouched; it never re-implements the handoff and never touches a broker\n//! resource.\n//!\n//! **C1 (this commit)** adds the verify-before-handoff gate ([`release`]): a\n//! release is signature-verified ([`REQ-UPD-2`]) and hardened against rollback\n//! ([`REQ-HAZARD-UPDATE-ROLLBACK`]) — Ed25519 over signed metadata, key\n//! trust/revocation, channel pinning, metadata expiry, monotonic version, and a\n//! SHA-256 binding the signature to the actual binary bytes. [`plan_verified`] is\n//! the front door: it produces an [`UpdatePlan`] *only* for a release that passes\n//! every check, so an unverified binary can never reach [`apply_brain_only`].\n//!\n//! **C3 (this commit)** conducts the **adapter ripple** ([`adapter_update`]):\n//! after self-update, spt-core updates each registered adapter via its manifest\n//! `[update]` avenue ([`REQ-UPD-5`], [`REQ-SEAM-UPDATE`]). `file_pull` payloads\n//! are verified against the **adapter's own** key (manifest-declared) + SHA-256\n//! (adapter content signing, ADR-0004 §D); `delegated` updaters are opaque, so\n//! spt-core delegates the trust only when the adapter attests `self_verifies`,\n//! else skips them as unverifiable.\n//!\n//! **D4b (this commit)** makes broker-held QUIC streams survive brain restarts\n//! **gaplessly and exactly-once** (Spike #3 invariants A–D as real tests): each\n//! stream's reads are buffered in a sequenced ring (the B2 `OutputLog`\n//! discipline) a brain subscribes to with a resume cursor; sends/opens carry\n//! durable `op_id`s journaled at the broker, so a restarted brain's re-drive\n//! dedups instead of double-writing the wire.\n//!\n//! **D4a (this commit)** moves the node's network presence into the broker\n//! ([`nethost::NetHost`], ADR-0004 §B): a dedicated tokio runtime hosts the\n//! iroh endpoint + every accepted/dialed QUIC connection, so a brain restart\n//! never interrupts a cross-node connection. The brain drives net operations\n//! (endpoint-status, dial) over new IPC frames in the same forward-compatible\n//! catalog; an `op_id`-carrying dial is exactly-once through the B5\n//! [`effect::EffectJournal`]. The endpoint binds as the durable node identity\n//! (`spt-store`'s `node.key`), with the relay stance from `daemon.json`.\n//!\n//! **D5a (this commit)** puts WAN message delivery on the D4 substrate: a\n//! [`WanMessage`](spt_net::net::wanmsg::WanMessage) NDJSON feed over a\n//! broker-owned QUIC stream funnels through [`wan::receive_wan`] — the ADR-0009\n//! access-gate seam ([`access`], handshake-proven origin only, KNOWN-HAZARDS\n//! 7.5) plus durable op-id dedup (7.2, wire-fed) — into the existing local\n//! REQ-MSG delivery path.\n//!\n//! **D5b (this commit)** adds remote terminal attach ([`attach`], REQ-INST-8):\n//! a byte-stream viewport onto a local session for an operator daemon on\n//! another node — session output pumped as sequenced\n//! [`AttachRecord`](spt_net::net::attach::AttachRecord)s (deduped at the\n//! operator's render cursor), operator input through the B5 exactly-once PTY\n//! path, the whole loop gated and restart-survivable purely from the D4/B5\n//! machinery.\n//!\n//! The brain + gapless handoff (B2) and the rest of the M3b task table build on\n//! this seam. `spt-daemon` is internal supervisor machinery, **not** public SDK\n//! (R-ARCH-2).\n//!\n//!

Just run:\n\n```powershell\n& \"C:\\Users\\decid\\.claude\\skills\\self-clear\\scripts\\self-clear.ps1\"\n```\n\nExpect: `SELF-CLEAR armed: id=<agent_id> winpid=<n> hwnd=<n> — /clear queued; self-note typed in ~10s`\n\nThen stop — end your turn promptly so the queued `/clear` fires.\n\n## What the script does\n\n1. `owl whoami` → resolves this session's `agent_id` (context-independent, survives the wipe). No perch → it aborts WITHOUT clearing and tells you to `/spt:ready` or `/spt:live` first.\n2. Walks the parent chain (`pwsh → claude.exe → … → WindowsTerminal`) to the ancestor that owns the window, foregrounds it.\n3. Types `/clear` + Enter — **queued**; only fires when this turn ends.\n4. Spawns a **detached** waker: waits 10s (past turn-end + wipe), re-foregrounds the terminal via the arm-time `hwnd`/`winpid`, then **types** `NOTE FROM THE USER: proceed with next steps.` + Enter as a fresh user prompt.\n\nThe 10s delay + detachment are deliberate: the prompt must be typed **after**\n`/clear` takes effect, so it lands on the clean context and starts a new turn.\n\nWhy typed, not `owl send`: after `/clear` the session sits idle awaiting user\ninput. A spooled owl message can't self-start a turn — it surfaces only during an\nalready-active turn (PreToolUse hook) or in a live Monitor stream (whose buffer\n`/clear` wipes). So a self-addressed owl note never woke the agent. A typed prompt\ndeterministically starts a turn AND is the re-seed.\n\n## Caveats\n\n- Window focus brings the whole terminal forward; it can't target a specific tab. Clean when the agent's tab is active.\n- The note is typed via SendKeys, so the terminal must stay the foreground-able window of `winpid`. Don't close/replace the terminal in the ~10s gap.\n- SendKeys reserves `+ ^ % ~ ( ) { } [ ]`; the default note text uses none. If you customize the note, escape those chars.\n- If your turn runs longer than ~10s after the script returns, the prompt could be typed before the wipe completes. Stop promptly after running.\n\n\nARGUMENTS: D5 COMPLETE (a:caab433 b:4ea3b37 c:269b8ef+fcad41c d:f49aba1, all CI-green). Next body: D6 Psyche sync.
