D9 E2E rig: gravity-linux + a Windows host.</psyche-context>\\n\\n<spacetime-reorientation agent_id=\\\"doyle\\\">\\nYou are agent \\\"doyle\\\". 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. You may still message your Psyche directly with $OWL send or $OWL ring if needed.\\n</spacetime-reorientation>\"}}\n","stderr":"","exitCode":0,"command":"$CLAUDE_PLUGIN_ROOT/owl.exe plugin-session-start","durationMs":845},"type":"attachment","uuid":"cc169a45-0d73-47d4-8230-a630a355a219","timestamp":"2026-06-03T19:25:55.481Z","userType":"external","entrypoint":"cli","cwd":"C:\\Users\\decid\\Documents\\projects\\spt-core","sessionId":"49a88be4-e407-4f89-8f82-38cada9f163b","version":"2.1.156","gitBranch":"HEAD"}

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. Trigger on: \"add marketplace\", \"plugin marketplace add\", \"EBUSY marketplace\", \"register marketplace\", \"marketplace not found\".\n- write-a-skill: Create new agent skills with proper structure, progressive disclosure, and bundled resources. Use when user wants to create, write, or build a new skill.\n- ccs: Delegate task with intelligent profile selection [AUTO ENHANCE]\n- ccs:continue: Continue last CCS delegation session [AUTO ENHANCE]\n- deep-research: Deep research harness — fan-out web searches, fetch sources, adversarially verify claims, synthesize a cited report. - When the user wants a deep, multi-source, fact-checked research report on any topic. BEFORE invoking, check if the question is specific enough to research directly — if underspecified (e.g., \"what car to buy\" without budget/use-case/region), ask 2-3 clarifying questions to narrow scope. Then pass the refined question as args, weaving the answers in.\n- frontend-design:frontend-design: Create distinctive, production-grade frontend interfaces with high design quality. Use this skill when the user asks to build web components, pages, or applications. Generates creative, polished code that avoids generic AI aesthetics.\n- spt:clear-psyche: Clear stored Psyche context. 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. For past sessions, restores a summarized context.\n\nEXPLICIT START phrases (route to /spt:live <id>):\n- \"live as\"\n- \"start live\"\n- \"go live\"\n- \"start a live agent\"\n\nAUTO-RESUME phrases (route to /spt:live --auto, resumes most-recently-active live agent):\n- continue live work\n- resume live work\n- continue live agent\n- resume live agent\n- live agent continue\n- live agent resume\n- live work continue\n- live work resume\n\nDoes NOT route here (too ambiguous — require BOTH \"live\" AND (\"agent\" or \"work\")):\n- \"keep going\"\n- \"resume work\"\n- \"continue\" (bare)\n- spt:new-alarm: Schedule a one-shot timed alarm delivered as TIMED PULSE. 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 says \"send to\",\n\"message\", \"tell <agent>\", or wants to communicate with another agent.\n- spt:signoff: Graceful live agent shutdown with final context summary. Use when the user\nsays \"sign off\", \"graceful stop\", or wants to cleanly end a live session.\n- spt:whoami: Check which owl agent belongs to the current session. 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":157,"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","deep-research","frontend-design:frontend-design","spt:clear-psyche","spt:commune","spt:force-stop","spt:list-agents","spt:live","spt:new-alarm","spt:psyche-sync-setup","spt:ready","spt:revive","spt:send","spt:signoff","spt:whoami","caveman:caveman","caveman:caveman-commit","caveman:caveman-help","caveman:caveman-review","caveman:compress","everything:search","update-config","keybindings-help","verify","code-review","simplify","fewer-permission-prompts","loop","schedule","claude-api","run","init","review","security-review"]},"type":"attachment","uuid":"d1cff2e6-aa57-4050-abd3-04b07a536290","timestamp":"2026-06-03T19:26:00.979Z","userType":"external","entrypoint":"cli","cwd":"C:\\Users\\decid\\Documents\\projects\\spt-core","sessionId":"49a88be4-e407-4f89-8f82-38cada9f163b","version":"2.1.156","gitBranch":"HEAD"}

The research brief vetted Ed25519 identity, Noise, Magic-Wormhole-style PAKE, and TOFU. The product question is the day-one pairing UX for a single user's own machines.\n10\t\n11\tA natural-seeming option is TOTP: the user provisions a seed into an authenticator app and pairs future nodes with the rotating 6-digit code. Used the obvious way (a new node sends the code to a trusted node for verification), this is insecure: the code is a ~20-bit bearer token, replayable within its 30s window, not bound to the key being exchanged — a real-time MITM can replay the code with their own pubkey and join the subnet. It also performs no key exchange, requiring a separate unbound handshake.\n12\t\n13\t## Decision\n14\t\n15\tAdopt **TOTP-seeded SPAKE2 pairing**: keep the familiar TOTP UX but use the 6-digit code as the **password for a SPAKE2 (PAKE) handshake**, not as a verified bearer token.\n16\t\n17\t- The TOTP **seed** is the durable subnet secret: generated on the first node, shown as a QR for the user's authenticator app, and replicated to every already-trusted node.\n18\t- To pair a new node, a trusted node (online, no human — it holds the seed) computes the current code as its SPAKE2 password; the user reads the code off their phone and types it into the new node as its password. Matching codes → PAKE succeeds → pubkeys exchanged + bound, MITM-resistant encrypted channel.\n19\t\n20\tPAKE is the correct primitive for a low-entropy human-transcribed secret: it resists offline brute force (one online guess per attempt) and binds the code to the established key. Cryptographic strength comes from the PAKE construction, not from the 6 digits being secret.\n21\t\n22\tRejected alternatives:\n23\t- **TOTP-as-bearer-token** — replayable, unbound, MITM-vulnerable (above).\n24\t- **Plain Magic Wormhole / fresh-code-each-time** — secure, but needs a human/relay at *both* ends each pairing. TOTP-seeded PAKE keeps the persistent seed on online trusted nodes so the user interacts only with the new node.\n25\t- **Paste-the-key** — too error-prone for \"just works.\"\n26\t- **Account-anchored auto-trust** — reintroduces the account dependency the product is shedding.\n27\t\n28\tTrust model: local per-node trust store of authorized peer pubkeys; TOFU after pairing (accept on first post-ceremony connect, warn on key change). Cross-subnet (two different users) is out of scope for v1.\n29\t\n30\t## Consequences\n31\t\n32\t- A seed-holder node must be online and reachable by the untrusted new node at pairing time; the relay/discovery layer must permit pre-trust contact on a dedicated pairing ALPN.\n33\t- Operational details to implement: ±1 TOTP window tolerance, handshake-attempt rate limiting, QR re-provisioning for recovery from any still-trusted node.\n34\t- Losing all nodes *and* the authenticator seed makes the subnet unrecoverable — must be documented.\n35\t- Revocation of a paired node is a separate trust-store delete; TOTP gates joining only, not continued membership.\n36\t- Adds a SPAKE2 + TOTP dependency to the core crypto surface (both have mature Rust crates per the research brief).\n37\t- Because every paired node holds the seed, the current code is fetchable from any trusted node (`spt pair --code` or via an agent) — no phone needed if a trusted node is handy. The user is prompted to **name the subnet** on first pairing; the name is shown on every subsequent pairing for confidence as the fleet grows.\n38\t\n39\t## Stage A red-team amendments (2026-05-31)\n40\t\n41\tCodex (`docs/reviews/STAGE-A-codex-redteam.md`) found three issues; resolve before M4 builds pairing:\n42\t\n43\t- **FATAL #10 — trust-store delete is NOT revocation.** The \"revocation = trust-store delete; TOTP gates joining only\" consequence above is false in the threat model: the seed is replicated to every trusted node, so a compromised node/seed can re-pair as a *new* node after deletion. **Required:** a seed **epoch + rotation** protocol — removing a compromised node rotates the subnet seed so the old node/old seed cannot rejoin. Pairing transcript must bind the seed epoch.\n44\t- **SERIOUS #11 — SPAKE2's one-online-guess bound needs subnet-global rate limiting.** A public pre-trust relay + multiple seed-holding nodes enables *distributed* guessing, and a ±1 TOTP acceptance window triples the valid-password space. **Required:** one active pairing ceremony per subnet, shared attempt counter, exponential backoff; justify or drop the ±1 window.\n45\t- **SERIOUS #12 — \"PAKE binds pubkeys\" only if the transcript does.** Must explicitly bind roles, both node pubkeys, subnet ID, TOTP time-step, and confirmation MACs, or unknown-key-share / reflection / wrong-subnet pairing remain. **Required:** full pairing-transcript spec + negative tests (MITM, replay, reflection, wrong subnet, stale time-step).\n46\t\n47\t## Multi-subnet amendment (2026-06-01 — see ADR-0006)\n48\t\n49\tADR-0006 makes a node a member of *multiple* subnets. The pairing ceremony is refined (not reversed) accordingly:\n50\t\n51\t- **Discovery takes two inputs: TOTP code + subnet-name.** The code is also the relay rendezvous selector, but a 6-digit code is a weak global selector, so the subnet-name namespaces the rendezvous. This is the **unified rule for all cases** — there is no node-name mode.\n52\t- **\"Create-new subnet\" names the subnet at creation.** One machine generates the new seed *and* runs the R-PAIR-4 naming prompt up front (becoming the sole seed-holder); the joiner then uses that subnet-name + the new seed's code.

The research brief vetted Ed25519 identity, Noise, Magic-Wormhole-style PAKE, and TOFU. The product question is the day-one pairing UX for a single user's own machines.\n\nA natural-seeming option is TOTP: the user provisions a seed into an authenticator app and pairs future nodes with the rotating 6-digit code. Used the obvious way (a new node sends the code to a trusted node for verification), this is insecure: the code is a ~20-bit bearer token, replayable within its 30s window, not bound to the key being exchanged — a real-time MITM can replay the code with their own pubkey and join the subnet. It also performs no key exchange, requiring a separate unbound handshake.\n\n## Decision\n\nAdopt **TOTP-seeded SPAKE2 pairing**: keep the familiar TOTP UX but use the 6-digit code as the **password for a SPAKE2 (PAKE) handshake**, not as a verified bearer token.\n\n- The TOTP **seed** is the durable subnet secret: generated on the first node, shown as a QR for the user's authenticator app, and replicated to every already-trusted node.\n- To pair a new node, a trusted node (online, no human — it holds the seed) computes the current code as its SPAKE2 password; the user reads the code off their phone and types it into the new node as its password. Matching codes → PAKE succeeds → pubkeys exchanged + bound, MITM-resistant encrypted channel.\n\nPAKE is the correct primitive for a low-entropy human-transcribed secret: it resists offline brute force (one online guess per attempt) and binds the code to the established key. Cryptographic strength comes from the PAKE construction, not from the 6 digits being secret.\n\nRejected alternatives:\n- **TOTP-as-bearer-token** — replayable, unbound, MITM-vulnerable (above).\n- **Plain Magic Wormhole / fresh-code-each-time** — secure, but needs a human/relay at *both* ends each pairing. TOTP-seeded PAKE keeps the persistent seed on online trusted nodes so the user interacts only with the new node.\n- **Paste-the-key** — too error-prone for \"just works.\"\n- **Account-anchored auto-trust** — reintroduces the account dependency the product is shedding.\n\nTrust model: local per-node trust store of authorized peer pubkeys; TOFU after pairing (accept on first post-ceremony connect, warn on key change). Cross-subnet (two different users) is out of scope for v1.\n\n## Consequences\n\n- A seed-holder node must be online and reachable by the untrusted new node at pairing time; the relay/discovery layer must permit pre-trust contact on a dedicated pairing ALPN.\n- Operational details to implement: ±1 TOTP window tolerance, handshake-attempt rate limiting, QR re-provisioning for recovery from any still-trusted node.\n- Losing all nodes *and* the authenticator seed makes the subnet unrecoverable — must be documented.\n- Revocation of a paired node is a separate trust-store delete; TOTP gates joining only, not continued membership.\n- Adds a SPAKE2 + TOTP dependency to the core crypto surface (both have mature Rust crates per the research brief).\n- Because every paired node holds the seed, the current code is fetchable from any trusted node (`spt pair --code` or via an agent) — no phone needed if a trusted node is handy. The user is prompted to **name the subnet** on first pairing; the name is shown on every subsequent pairing for confidence as the fleet grows.\n\n## Stage A red-team amendments (2026-05-31)\n\nCodex (`docs/reviews/STAGE-A-codex-redteam.md`) found three issues; resolve before M4 builds pairing:\n\n- **FATAL #10 — trust-store delete is NOT revocation.** The \"revocation = trust-store delete; TOTP gates joining only\" consequence above is false in the threat model: the seed is replicated to every trusted node, so a compromised node/seed can re-pair as a *new* node after deletion. **Required:** a seed **epoch + rotation** protocol — removing a compromised node rotates the subnet seed so the old node/old seed cannot rejoin. Pairing transcript must bind the seed epoch.\n- **SERIOUS #11 — SPAKE2's one-online-guess bound needs subnet-global rate limiting.** A public pre-trust relay + multiple seed-holding nodes enables *distributed* guessing, and a ±1 TOTP acceptance window triples the valid-password space. **Required:** one active pairing ceremony per subnet, shared attempt counter, exponential backoff; justify or drop the ±1 window.\n- **SERIOUS #12 — \"PAKE binds pubkeys\" only if the transcript does.** Must explicitly bind roles, both node pubkeys, subnet ID, TOTP time-step, and confirmation MACs, or unknown-key-share / reflection / wrong-subnet pairing remain. **Required:** full pairing-transcript spec + negative tests (MITM, replay, reflection, wrong subnet, stale time-step).\n\n## Multi-subnet amendment (2026-06-01 — see ADR-0006)\n\nADR-0006 makes a node a member of *multiple* subnets. The pairing ceremony is refined (not reversed) accordingly:\n\n- **Discovery takes two inputs: TOTP code + subnet-name.** The code is also the relay rendezvous selector, but a 6-digit code is a weak global selector, so the subnet-name namespaces the rendezvous. This is the **unified rule for all cases** — there is no node-name mode.\n- **\"Create-new subnet\" names the subnet at creation.** One machine generates the new seed *and* runs the R-PAIR-4 naming prompt up front (becoming the sole seed-holder); the joiner then uses that subnet-name + the new seed's code. Naming simply moves to link-start.\n- **Rendezvous-token hashing.** The relay routes the pre-trust ceremony by `H(subnet-name ‖ TOTP-epoch)`, not the plaintext label — the user/agent enters the raw name + code; the hash is internal. (Payload is already E2E-encrypted; this protects the relay-visible routing token from leaking the human subnet label.) Composes with the #12 transcript binding (the subnet ID / seed epoch already in the transcript).\n- **Per-subnet code fetch is gated behind OS elevation** (Windows UAC / Linux root-or-equivalent), or an elevated agent endpoint; else the user falls back to their authenticator app. Replaces the old unqualified \"fetchable from any trusted node\" with an elevation-gated, *per-subnet* fetch (a node now holds several subnets' seeds).\n- **Code fetch is per-subnet** (a node holds *N* seeds): `spt pair show-totp` prompts which subnet (or `--subnet <name>` / `--create-new` to bypass), offered optionally as a QR / `otpauth://` URI.\n- **Forward (cross-user, ADR-0006 seam):** the seed key becomes per-(subnet, user); the prompt becomes 2-stage.

Context: Rust workspace already uses ed25519-dalek v2, sha2 0.10, curve25519 ecosystem implied. Need three things:\n\n1. **SPAKE2 (PAKE) crate.** Find the best-maintained Rust SPAKE2 implementation. Check the RustCrypto `spake2` crate (formerly Brian Warner's port): latest version on crates.io, last release date, maintenance status, API shape (how you create Spake2::start_a / start_b / symmetric, the password input type, finish() returning the shared key), what curve/hash it uses (curve25519-dalek? which version — must not conflict with ed25519-dalek v2's curve25519-dalek), and whether it produces a transcript/confirmation-MAC or whether the caller must add key-confirmation themselves. Note any RUSTSEC advisories. Compare against any alternative SPAKE2/CPace/OPAQUE crates if the main one is unmaintained. CRITICAL question: does the spake2 crate bind identities/transcript, or do we layer our own confirmation MAC (HMAC over roles+both pubkeys+subnet ID+seed epoch+TOTP step) on top of the raw PAKE shared secret?\n\n2. **TOTP.** Either a crate (`totp-rs`, `totp-lite`) or roll-our-own RFC 6238 with hmac+sha1. Report the cleanest minimal option that lets us: generate a random seed, render an otpauth:// URI + QR, compute the current 6-digit code AND adjacent steps (±1 window), and expose the raw time-step counter (we need the step value to bind into the SPAKE2 transcript, not just the 6-digit string).

Context: Rust workspace already uses ed25519-dalek v2, sha2 0.10, curve25519 ecosystem implied. Need three things:\n\n1. **SPAKE2 (PAKE) crate.** Find the best-maintained Rust SPAKE2 implementation. Check the RustCrypto `spake2` crate (formerly Brian Warner's port): latest version on crates.io, last release date, maintenance status, API shape (how you create Spake2::start_a / start_b / symmetric, the password input type, finish() returning the shared key), what curve/hash it uses (curve25519-dalek? which version — must not conflict with ed25519-dalek v2's curve25519-dalek), and whether it produces a transcript/confirmation-MAC or whether the caller must add key-confirmation themselves. Note any RUSTSEC advisories. Compare against any alternative SPAKE2/CPace/OPAQUE crates if the main one is unmaintained. CRITICAL question: does the spake2 crate bind identities/transcript, or do we layer our own confirmation MAC (HMAC over roles+both pubkeys+subnet ID+seed epoch+TOTP step) on top of the raw PAKE shared secret?\n\n2. **TOTP.** Either a crate (`totp-rs`, `totp-lite`) or roll-our-own RFC 6238 with hmac+sha1. Report the cleanest minimal option that lets us: generate a random seed, render an otpauth:// URI + QR, compute the current 6-digit code AND adjacent steps (±1 window), and expose the raw time-step counter (we need the step value to bind into the SPAKE2 transcript, not just the 6-digit string). Lots of TOTP crates hide the counter — flag which expose it.\n\n3. **QR / otpauth provisioning.** Smallest crate to emit an otpauth:// URI and a QR (terminal or PNG). e.g. `qrcode` crate.\n\nOutput a concise recommendation table: crate | version | last-release | why | risk.

Owns the PTYs for all hosted sessions, the node's network identity + WAN endpoint, the subnet registry, all spools, **all poll-listener logic, and all Psyche/pulse loops** — everything is consolidated here (no separate poll-listener or Psyche-wrapper processes; listeners already touch sessions directly under capsule/idle, and Psyche wrappers already invoke harness binaries directly, so they belong in the one supervisor). Collapses what the sister project planned as a separate `spt-node` daemon into one process — see Networking. The `spt-node` separate-deliverable concept is retired.\n109:**capability declaration** — which endpoint types a harness/node can host (a Pi node might host only Shells, never a LiveAgent). Static manifest list, consumed by the subnet registry so a node advertises its hostable types. Exact shape is design-open.\n185:A machine's participation in an SPT subnet, identified by an Ed25519 public key generated on first run. First-class so networking primitives can address nodes directly as message targets, not only as transport peers. The node identity and network endpoint are hosted by the machine's `spt-daemon` (see Networking), not a separate process.\n233:**Broadcast policy** (manifest): the shell advertises its availability to all agents on the subnet, only same-node agents, or not at all (agents learn of it only by user instruction). Shells run only on nodes where the shell adapter is installed/advertised.\n252:**Discovery scope (what \"available shells\" resolves to):** the set surfaced to an agent (injected + `shell list`) is **(1)** its **own instances** — alias · canonical `<adapter>-<n>` · status — always; plus **(2) instantiable adapters**: shell adapters **registered on the agent's own node** with `broadcast ∈ {subnet, same-node}`, and shell adapters on *other* subnet nodes with `broadcast = subnet`. `broadcast = none` shells are **never** surfaced proactively — spawnable only by explicit user/agent instruction (if registered locally / reachable). Discovering an *other-node* shell does **not** imply free instantiation: spawning it rides the deferred **instantiate-anywhere** gate. (Discovery is gated by the same reach gates as everything else — an agent only sees shells on nodes/subnets it can address.)\n254:**Not in the subnet registry.** Shell perches are private to the agent↔shell link, not a general messaging surface — they are nested under the owner (`perches/<endpoint_id>/shells/<adapter>-<n>/`) and not registry-advertised like agent endpoints. The perch `info.json` carries only `type=Shell`, `owner`, `adapter_name`, `status` (online|offline), and an optional `alias` — the capability set is resolved from the shell adapter manifest by `adapter_name`, not duplicated on the perch.\n269:**Wake resolution (state-keyed):** find any *reachable* instance of the owner endpoint on the subnet, then —\n298:- **Two access modes over one transport.** The digest is a *parsed projection of the same PTY stream the broker already owns for byte-stream remote terminal (R-TERM-3)*, so it is offered both ways: **snapshot pull** — `spt digest <[subnet:]id[@node]>` returns the current structured buffer (a Shell/CLI/GUI on-demand render; feeds the frontend's \"latest session output\" pane) — and a **broker-pushed structured-delta stream** — a subscriber (live Shell pane / GUI) receives only *changes* (new turn, new tool entry, collapse update), not the whole buffer, for resource-efficient near-realtime reflection. The delta-stream is a **structured overlay riding the same R-TERM-3 streaming substrate** as the raw byte-stream (raw bytes vs parsed digest = two channels on the one session surface). **Access is address-gated** — fetch/subscribe is allowed for anyone who can address the endpoint (visible + resolvable per the resolution policy), the same gate as messaging.\n303:WAN cross-machine messaging is a **first-class, day-one capability** of spt-core — not a follow-on project. Goal: minimal-to-zero config, \"just works\" cross-machine SPT. The transport stack (Iroh + mDNS LAN discovery + pairing) is baked into the core library crates, behind a compile-time feature flag (`net`) that is default-on in the reference binary and optional for embedded/stripped library consumers.\n318:**Sync scope is subnet-exclusive by default.** An endpoint's mind replicates only within **one subnet** unless told otherwise. Endpoint config carries a **subnet-membership list** for sync: the context syncs across the nodes of *every* subnet in that list, defaulting to just the endpoint's home subnet. This is distinct from registry *visibility* (*endpoint visibility*) — being addressable in a subnet does not imply replicating your mind there; mind-replication into a subnet requires that subnet to be in the sync list. The default keeps a `home`-fleet agent's mind off the `work` fleet even when a node bridges both. (The subnet scope composes with the live/project tier split below: a tier syncs to the eligible instances *that are also in an in-scope subnet*.)\n322:- **Hub (opt-in, `spt context-github-setup`):** every node pull→merge→pushes against a private GitHub remote — an always-online sync hub *and* a convenient GUI view. Uses a **shared deploy key** distributed as subnet secret material, so only the setup node needs a GitHub account; other nodes use the key over SSH, with **P2P as backstop**. Hub mode is the **context-repo sync transport only** — messaging, registry, remote-drive, pairing, and presence always ride P2P; gh-on never removes the P2P requirement (ADR-0002, amended).\n326:### Subnet notifications\n329:A first-class kind **distinct from an inter-agent message**: a **user-directed, dismissable, resurfacing** subnet event (e.g. *new node paired*, *external-subnet pairing request*, *update available*, *consent needed*). Messages route agent→agent and are consumed once; notifs route **to the user** — via whichever endpoint is active — and **persist until dismissed**. The notif is the general primitive that the previously-ad-hoc \"deliver to the user's most-recently-active session\" flows are special cases of: **the self-update prompt and the consent escalation are refactored to be notif producers** (one primitive, many producers — kills the duplicated delivery paths; the registry-resolution precursor to PresenceChannel is this primitive's delivery step).\n331:- **Spool: per-subnet, replicated across that subnet's nodes** (reuses subnet-registry distribution). Each notif is tagged with its subnet; **dismiss-state replicates subnet-wide**, eventually consistent (dismiss on node A clears it on node B). \"Node notif spool\" = each node's local replica. *(Forward seam: dismissal — and the spool key — generalize to **per-(subnet, user)** when the cross-user model lands.)*\n332:- **First-fire** targets the user's most-recently-active endpoint *in that subnet* via presence resolution.\n335:- **Scope:** an endpoint only ever sees/resurfaces notifs for subnets it is **visible in** (excluded endpoints never receive that subnet's notifs).\n337:- **Producers (open set):** system events (node-paired, pairing-request, update-available, consent-needed) + agent-issued `spt notify`. New producers register later.\n338:- **Envelope `from`** — for agent-issued notifs carries the issuer's **endpoint id, node, and subnet** (the subnet is **surfaced to the receiver only if its node is on multiple subnets** — otherwise redundant). Makes notifs attributable now and targetable once the per-(subnet, user) model lands.\n340:**`spt notify` (agent-issued subnet notif)**:\n341:A command letting any agent **issue a subnet-wide notif** to the user. v1: it **reaches the user on their active endpoint from any agent** (the default broadcast-to-user). *Forward:* gains targeting — **all subnet users (default) or specific subnet users** — once the per-(subnet, user) model lands; the `from` field is what makes targeted/attributed delivery possible.\n347:**delivery** — peer-propagated over P2P, layered on self-fetch, with out-of-band still supported. One node learns of / obtains an update (marketplace drop *or* self-fetch from a release channel), gossips availability across the subnet, and peers pull the new binary over the networking layer — the subnet self-heals to latest. **All binaries are signature-verified before handoff regardless of source** (peer-propagation otherwise lets a compromised node poison the subnet). spt-core has its own release signing key, distinct from any OS-publisher code-signing (the Windows-publisher-trust question is separate).\n360:The logical identity (`ling`). Shared subnet-wide. The thing you address. **Adapter-agnostic**: the same ID can run under different adapters over its life (start on `claude-spt`, later revive on `spt-codex` or `spt-pi`) — adapters expose the same SPT-relevant capability subset, so the ID is not bound to an adapter. The currently-running `adapter_name` is a property of the live instance, not part of the identity. **At most one instance of an ID per node** is allowed; a second attempt on the same node (any adapter) is rejected. **Identity is node-global, advertised per-subnet** (see *subnet membership*): one `ling` exists on a node (one mind, one `tracked/` context) and is advertised into each subnet the node belongs to, subject to per-subnet visibility (see *endpoint visibility*). The same bare name may exist as *distinct* endpoints in different subnets; the resolution policy forces qualification when both are visible. Within a single subnet a bare id is unique — enforced by a **join-time collision check**: when a node carrying endpoint `X` joins/advertises into a subnet that already has a different `X`, the clash is surfaced and resolved (rename one — below) before advertisement. An endpoint keeps an **ordered adapter history** (in `tracked/agents/<id>/meta.json`, synced) driving the resume UX: latest adapter is the default resume offer, then next-latest, … oldest, then \"choose a different adapter\". (Adapter-agnosticism is an *agent-endpoint* property; Shells are adapter/platform-bound — see Shells.)\n363:At **creation**, the adapter is chosen from the node's **registered `kind=\"harness\"` adapters whose `hostable_types` includes the endpoint's type** — **auto if exactly one qualifies, else chosen** (`--adapter` / picker): the same *auto-if-one-ask-if-many* rule as *home subnet*. The choice seeds the **head of the ordered adapter history** and the live `adapter_name`. **Changing** an endpoint's adapter is **not** a standalone operation — adapter is a *live-instance* property, so you change it by **launching/resuming the endpoint under a different registered adapter** (the resume UX surfaces the adapter history: head = default, then prior adapters, then \"choose a different adapter\"). For a currently-active instance this is a **resume-under-the-new-adapter** carrying context via the *fresh-with-preload* psyche-download (a session cycle, not a hot swap — the mind is adapter-agnostic). Same gate both times: the target adapter must be **registered on the node** and its `hostable_types` must include the endpoint's type.\n389:**`spt rename <id> <new_id>`** (endpoint rename, **rippled**): change an endpoint's logical ID and propagate the change to **all its instances** subnet-wide — the registry entries, every node's perch, and the synced context branches (`a-<id>` → `a-<new_id>`, and project-view references). The rename is one logical operation against the eventually-consistent registry; it must collision-check `new_id` against every subnet the endpoint is advertised into (the join-time check above), and reconcile concurrent renames by the same precedence marker the context merge uses (node + newest-wins, KNOWN-HAZARDS 6.5). The adapter-agnostic, node-anchored identity (ADR-0003) is what makes a clean rename possible; without it the ID would be entangled with per-adapter or per-session state.\n391:**`spt fork <id> [--into <subnet>] [--as <new_id>] [--delete-source]`** (cross-subnet clone):\n392:Clone an endpoint into a **new, identity-distinct endpoint** on another subnet — the sanctioned way to place an agent's mind in a different subnet (home subnet being immutable). The fork's **home = the target subnet**; it is **seeded with a one-time copy** of the source's mind (the live + project *Cross-node Psyche sync* tiers), after which the two **diverge** — there is **no ongoing sync**. A fork is therefore **not an instance**: an *instance* is the **same** identity on another node with a **synced** mind; a *fork* is a **new** identity with a **copied-then-independent** mind. The new id defaults to the source's bare name if free in the target subnet (the join-time collision check; else prompt/rename); the adapter follows the normal creation rule (*adapter selection*). The **source is untouched**, optionally deleted afterward (`--delete-source`, or a later delete). Distinct from **rename** (same identity, new label, rippled) and **instantiate-anywhere** (same identity, new *node*, consent-gated).\n405:**subnet registry**:\n406:Distributed, 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.\n408:**endpoint visibility (per-(endpoint, subnet))**:\n409:Whether 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.\n411:**home subnet (per endpoint)**:\n412:The 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).\n414:**resource advertisement (subnet resource registry)**:\n415:A 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).\n418:How 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).\n443:- **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.\n451:Layering (bottom → top): `spt-proto` (wire envelope grammar, endpoint types, message framing, Ed25519 identity types, typed+binary payload schema — pure types, no I/O) → `spt-store` (spool, perch layout, trust store, registry persistence) → `spt-msg` (delivery TCP+spool-fallback, routing, send/ring) → `spt-net` (Iroh, mDNS, SPAKE2/TOTP pairing, subnet-registry distribution; `net` feature-flagged) and `spt-term` (session-surface trait, PTY impl, broker) and `spt-runtime` (`AgentRuntime` trait, `ManifestRuntime`, manifest schema) → `spt-live` (Psyche/pulse/commune/signoff) → `spt-daemon` (the brain: ties all, hosts broker, update orchestration, instance registry) → `spt` (the `spt.exe` binary; thin CLI).\n457:## Pairing & trust\n459:How a single user's own nodes come to trust each other and form a subnet. Cross-*user* subnet (two *different* users' subnets interoperating) is explicitly deferred (the sister project's \"cross-subnet contract\" — very-early future concept), but the model is **built with the seam for it** (see *subnet membership*).\n461:**subnet membership (multi-subnet)**:","is_error":false}]},"uuid":"29165752-2a47-4c5c-9f6d-074615cb2081","timestamp":"2026-06-03T19:29:12.601Z","toolUseResult":{"stdout":"26:The single always-on, one-per-machine logical supervisor.

New producers register later.\n338:- **Envelope `from`** — for agent-issued notifs carries the issuer's **endpoint id, node, and subnet** (the subnet is **surfaced to the receiver only if its node is on multiple subnets** — otherwise redundant). Makes notifs attributable now and targetable once the per-(subnet, user) model lands.\n340:**`spt notify` (agent-issued subnet notif)**:\n341:A command letting any agent **issue a subnet-wide notif** to the user. v1: it **reaches the user on their active endpoint from any agent** (the default broadcast-to-user). *Forward:* gains targeting — **all subnet users (default) or specific subnet users** — once the per-(subnet, user) model lands; the `from` field is what makes targeted/attributed delivery possible.\n347:**delivery** — peer-propagated over P2P, layered on self-fetch, with out-of-band still supported. One node learns of / obtains an update (marketplace drop *or* self-fetch from a release channel), gossips availability across the subnet, and peers pull the new binary over the networking layer — the subnet self-heals to latest. **All binaries are signature-verified before handoff regardless of source** (peer-propagation otherwise lets a compromised node poison the subnet). spt-core has its own release signing key, distinct from any OS-publisher code-signing (the Windows-publisher-trust question is separate).\n360:The logical identity (`ling`). Shared subnet-wide. The thing you address. **Adapter-agnostic**: the same ID can run under different adapters over its life (start on `claude-spt`, later revive on `spt-codex` or `spt-pi`) — adapters expose the same SPT-relevant capability subset, so the ID is not bound to an adapter. The currently-running `adapter_name` is a property of the live instance, not part of the identity. **At most one instance of an ID per node** is allowed; a second attempt on the same node (any adapter) is rejected. **Identity is node-global, advertised per-subnet** (see *subnet membership*): one `ling` exists on a node (one mind, one `tracked/` context) and is advertised into each subnet the node belongs to, subject to per-subnet visibility (see *endpoint visibility*). The same bare name may exist as *distinct* endpoints in different subnets; the resolution policy forces qualification when both are visible. Within a single subnet a bare id is unique — enforced by a **join-time collision check**: when a node carrying endpoint `X` joins/advertises into a subnet that already has a different `X`, the clash is surfaced and resolved (rename one — below) before advertisement. An endpoint keeps an **ordered adapter history** (in `tracked/agents/<id>/meta.json`, synced) driving the resume UX: latest adapter is the default resume offer, then next-latest, … oldest, then \"choose a different adapter\". (Adapter-agnosticism is an *agent-endpoint* property; Shells are adapter/platform-bound — see Shells.)\n363:At **creation**, the adapter is chosen from the node's **registered `kind=\"harness\"` adapters whose `hostable_types` includes the endpoint's type** — **auto if exactly one qualifies, else chosen** (`--adapter` / picker): the same *auto-if-one-ask-if-many* rule as *home subnet*. The choice seeds the **head of the ordered adapter history** and the live `adapter_name`. **Changing** an endpoint's adapter is **not** a standalone operation — adapter is a *live-instance* property, so you change it by **launching/resuming the endpoint under a different registered adapter** (the resume UX surfaces the adapter history: head = default, then prior adapters, then \"choose a different adapter\"). For a currently-active instance this is a **resume-under-the-new-adapter** carrying context via the *fresh-with-preload* psyche-download (a session cycle, not a hot swap — the mind is adapter-agnostic). Same gate both times: the target adapter must be **registered on the node** and its `hostable_types` must include the endpoint's type.\n389:**`spt rename <id> <new_id>`** (endpoint rename, **rippled**): change an endpoint's logical ID and propagate the change to **all its instances** subnet-wide — the registry entries, every node's perch, and the synced context branches (`a-<id>` → `a-<new_id>`, and project-view references). The rename is one logical operation against the eventually-consistent registry; it must collision-check `new_id` against every subnet the endpoint is advertised into (the join-time check above), and reconcile concurrent renames by the same precedence marker the context merge uses (node + newest-wins, KNOWN-HAZARDS 6.5). The adapter-agnostic, node-anchored identity (ADR-0003) is what makes a clean rename possible; without it the ID would be entangled with per-adapter or per-session state.\n391:**`spt fork <id> [--into <subnet>] [--as <new_id>] [--delete-source]`** (cross-subnet clone):\n392:Clone an endpoint into a **new, identity-distinct endpoint** on another subnet — the sanctioned way to place an agent's mind in a different subnet (home subnet being immutable). The fork's **home = the target subnet**; it is **seeded with a one-time copy** of the source's mind (the live + project *Cross-node Psyche sync* tiers), after which the two **diverge** — there is **no ongoing sync**. A fork is therefore **not an instance**: an *instance* is the **same** identity on another node with a **synced** mind; a *fork* is a **new** identity with a **copied-then-independent** mind. The new id defaults to the source's bare name if free in the target subnet (the join-time collision check; else prompt/rename); the adapter follows the normal creation rule (*adapter selection*). The **source is untouched**, optionally deleted afterward (`--delete-source`, or a later delete). Distinct from **rename** (same identity, new label, rippled) and **instantiate-anywhere** (same identity, new *node*, consent-gated).\n405:**subnet registry**:\n406:Distributed, 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.\n408:**endpoint visibility (per-(endpoint, subnet))**:\n409:Whether 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.\n411:**home subnet (per endpoint)**:\n412:The 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).\n414:**resource advertisement (subnet resource registry)**:\n415:A 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).\n418:How 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).\n443:- **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.\n451:Layering (bottom → top): `spt-proto` (wire envelope grammar, endpoint types, message framing, Ed25519 identity types, typed+binary payload schema — pure types, no I/O) → `spt-store` (spool, perch layout, trust store, registry persistence) → `spt-msg` (delivery TCP+spool-fallback, routing, send/ring) → `spt-net` (Iroh, mDNS, SPAKE2/TOTP pairing, subnet-registry distribution; `net` feature-flagged) and `spt-term` (session-surface trait, PTY impl, broker) and `spt-runtime` (`AgentRuntime` trait, `ManifestRuntime`, manifest schema) → `spt-live` (Psyche/pulse/commune/signoff) → `spt-daemon` (the brain: ties all, hosts broker, update orchestration, instance registry) → `spt` (the `spt.exe` binary; thin CLI).\n457:## Pairing & trust\n459:How a single user's own nodes come to trust each other and form a subnet. Cross-*user* subnet (two *different* users' subnets interoperating) is explicitly deferred (the sister project's \"cross-subnet contract\" — very-early future concept), but the model is **built with the seam for it** (see *subnet membership*).\n461:**subnet membership (multi-subnet)**:","stderr":"","interrupted":false,"isImage":false,"noOutputExpected":false},"sourceToolAssistantUUID":"8d95a114-e943-4442-99cd-f3322eb183d8","userType":"external","entrypoint":"cli","cwd":"C:\\Users\\decid\\Documents\\projects\\spt-core","sessionId":"49a88be4-e407-4f89-8f82-38cada9f163b","version":"2.1.156","gitBranch":"HEAD"}

Cross-*user* subnet (two *different* users' subnets interoperating) is explicitly deferred (the sister project's \"cross-subnet contract\" — very-early future concept), but the model is **built with the seam for it** (see *subnet membership*).\n460\t\n461\t**subnet membership (multi-subnet)**:\n462\tA node may be a member of **multiple subnets at once** — but, for v1, only multiple subnets *of the same user* (e.g. a `home` fleet and a `work` fleet, each cryptographically its own TOTP seed + trust context). A node simply holds *N* seeds / trust-contexts rather than one. The per-subnet trust boundary is unchanged: within each subnet, all nodes are the one user's own mutually-trusted nodes (no stranger-auth). **Cross-*user* membership (joining another person's subnet) stays deferred**, but the membership model is multiplicity-ready so it can drop in later without re-architecture. An **external subnet** (relative to a given subnet) means *another subnet the node also belongs to* — in v1, always another of the user's own.\n463\t\n464\t**Cross-user seam (forward design, not v1):** the seed key generalizes from *per-subnet* to **per-(subnet, user)** — a seed then doubles as an identifier+authenticator for *whose* it is. The pairing/code prompt becomes **2-stage** (select user / create-new → then select subnet / create-new); in v1 the single implicit user collapses it back to the 1-stage prompt. This makes node↔user attribution fall out for free (\"node `enlyzeam` is using Brandon's `work` seed → that machine's active endpoint is Brandon's\") and makes **force-unlink of an entire user's node-group** a single operation (drop that user's seeds). v1 stores seeds in a shape that already accommodates the (subnet, user) key.\n465\t\n466\t**TOTP-seeded SPAKE2 pairing**:\n467\tThe day-one pairing model. A durable **TOTP seed** is the subnet secret: generated on the first node, shown as a QR → stored in the user's authenticator app *and* held by every already-trusted node. To pair a new node, the rotating 6-digit TOTP code is used as the **password for a SPAKE2 (PAKE) handshake** — *not* as a bearer token verified by a seed-holder. A trusted node (online, no human needed — it holds the seed) computes the current code as its PAKE password; the user reads the code off their phone and types it into the new node. Matching codes → PAKE succeeds → pubkeys exchanged and bound, MITM-resistant encrypted channel established.\n468\t\n469\tWhy this construction (not plain TOTP-verification, not plain Magic Wormhole):\n470\t- **Not TOTP-as-bearer-token** — a 6-digit code sent over the wire for verification is ~20 bits, replayable within its 30s window, and doesn't bind to the key being exchanged (real-time MITM/replay seam). PAKE makes the low-entropy code MITM-resistant and limits attackers to one online guess per attempt (no offline brute force).\n471\t- **Better UX than plain Magic Wormhole** — Wormhole needs a fresh code on one node typed into the other, requiring a human/relay at *both* ends each pairing. With the persistent TOTP seed replicated to online trusted nodes, the trusted side is automatic; **the user only ever interacts with the new node** (read phone, type into new machine).\n472\t\n473\t**trust store**:\n474\tEach node keeps a local store of authorized peer pubkeys. TOFU after pairing: accept on first connect post-ceremony, warn on key change. Lives near `node.key`.\n475\t\n476\t**link discovery (TOTP + name)**:\n477\tThe TOTP code is **also the link-discovery selector**, not only the PAKE password — it routes the two not-yet-trusted nodes to the same pairing rendezvous over the relay's pairing ALPN. Because a 6-digit code is a weak global selector, discovery+link takes **two inputs: the TOTP code + the subnet-name** (the R-PAIR-4 human label), which namespaces the rendezvous. **The subnet-name is the second input in all cases** (the unified rule):\n478\t- **join-existing** → enter the target subnet's name + its current code. Any online seed-holder of that subnet listens on that rendezvous and completes the PAKE; the joiner never enumerates the subnet's nodes.\n479\t- **create-new** → the subnet is **named at creation**: one machine generates the new seed *and names the subnet* up front (becoming the sole seed-holder), then the joiner uses that subnet-name + the new seed's code. No node-name mode — naming simply happens at link start rather than after.\n480\t\n481\tThe name only namespaces the rendezvous; a collision (two unrelated pairings sharing a code + name) merely fails the PAKE (wrong password) — no security break, just a retry. **Rendezvous-token hashing (under the hood):** the relay routes the *pre-trust* pairing by a rendezvous token; the payload is already E2E-encrypted (R-NET-2), but the token itself is relay-visible, so spt-core derives it as `H(subnet-name ‖ TOTP-epoch)` rather than the plaintext label — the user/agent still enters the **raw name + code**, the hash is internal.\n482\t\n483\t**fetch-code-from-any-node (per-subnet, QR-optional)**:\n484\tEvery node in a subnet holds that subnet's seed, so the user can fetch the *current* code for **any subnet the node belongs to** from any node in it — no phone required if a trusted node is handy. Because a node may be in several subnets (*subnet membership*), the fetch is **per-subnet**: CLI prompts *\"Show TOTP for which subnet? [subnet-1 … subnet-n | create new subnet]\"*, with **`--subnet <name>` / `--create-new`** flags to bypass the prompt (the agent-driven path). The code is offered optionally as a **QR / `otpauth://` URI** so the seed can be stored directly in an authenticator app (Google Authenticator etc.).\n485\t\n486\t**Node-bound code fetch is gated behind OS privilege elevation** (Windows UAC / Linux root-or-equivalent): retrieving a subnet's code *from the node* requires either hardware/elevated access OR an **elevated endpoint** (an agent whose process is elevated can surface it). This means the node-bound path proves real possession of the machine; everyone else falls back to **their own authenticator-app TOTP store** (where the seed was stored at pairing). The gate narrows the multi-subnet exposure — without elevation, mere CLI/agent presence on a node no longer yields *any* subnet's join-code; with it, node compromise still implies full trust loss for that node's subnets (unchanged baseline).\n487\t\n488\t**subnet naming**:\n489\tThe first time two nodes pair, the user is prompted to **name the subnet**. The name is a human label on the subnet identity (which is cryptographically the shared seed). On every subsequent pairing the same name is shown (\"adding node to subnet `<name>`\"), giving the user confidence they're extending the right subnet as the fleet grows.\n490\t\n491\t**subnet icon** (GUI metadata): an optional small image (square PNG/WebP, ≤256 KB) representing the subnet in future GUIs. Stored **inline** in subnet metadata (so it syncs for free over the same subnet-material channel as the name; the cap keeps inline-sync trivial — it's an icon, not a media library), **editable by any node in the subnet, any time** (seeded at create/name). **GUI-only consumer** (frontend milestone); data distribution rides M4.\n492\t\n493\tDesign caveats (carried forward, none disqualifying): a seed-holder must be online + reachable by the untrusted new node at pairing time (relay allows pre-trust contact on a pairing ALPN); ±1 TOTP window tolerance; rate-limit handshake attempts; **recovery** = re-provision the QR from any still-trusted node (all hold the seed) — losing all nodes *and* the auth app makes the subnet unrecoverable (documented); **revocation** of a paired node is a separate trust-store delete (TOTP gates joining only).\n494\t\n495\t**local-link authentication**:\n496\tCross-node traffic already rides Iroh (E2E-encrypted by node keypairs). The exposed surface is *same-node* channels where potentially-untrusted code touches SPT — a shell binary's HTTP/stdin/relay link, HTTP-to-harness-binary delivery. These require a **per-link handshake at `api bind` that establishes a link token + local-channel encryption**, required on every subsequent message — a local-link auth capability so other local processes can't inject into or read a link. Shell↔broker links specifically are encrypted + handshaked.\n497\t\n498\t**binary-trust disclosure (accepted risk)**:\n499\tA shell binary is the least-trusted code in the system (3rd-party, runs on the user's node, agent-controllable) — but the same is true of harness binaries. The capability toolset bounds what an *agent* may ask; it does not sandbox what the *binary* may do with its OS permissions.

Cross-*user* subnet (two *different* users' subnets interoperating) is explicitly deferred (the sister project's \"cross-subnet contract\" — very-early future concept), but the model is **built with the seam for it** (see *subnet membership*).\n\n**subnet membership (multi-subnet)**:\nA node may be a member of **multiple subnets at once** — but, for v1, only multiple subnets *of the same user* (e.g. a `home` fleet and a `work` fleet, each cryptographically its own TOTP seed + trust context). A node simply holds *N* seeds / trust-contexts rather than one. The per-subnet trust boundary is unchanged: within each subnet, all nodes are the one user's own mutually-trusted nodes (no stranger-auth). **Cross-*user* membership (joining another person's subnet) stays deferred**, but the membership model is multiplicity-ready so it can drop in later without re-architecture. An **external subnet** (relative to a given subnet) means *another subnet the node also belongs to* — in v1, always another of the user's own.\n\n**Cross-user seam (forward design, not v1):** the seed key generalizes from *per-subnet* to **per-(subnet, user)** — a seed then doubles as an identifier+authenticator for *whose* it is. The pairing/code prompt becomes **2-stage** (select user / create-new → then select subnet / create-new); in v1 the single implicit user collapses it back to the 1-stage prompt. This makes node↔user attribution fall out for free (\"node `enlyzeam` is using Brandon's `work` seed → that machine's active endpoint is Brandon's\") and makes **force-unlink of an entire user's node-group** a single operation (drop that user's seeds). v1 stores seeds in a shape that already accommodates the (subnet, user) key.\n\n**TOTP-seeded SPAKE2 pairing**:\nThe day-one pairing model. A durable **TOTP seed** is the subnet secret: generated on the first node, shown as a QR → stored in the user's authenticator app *and* held by every already-trusted node. To pair a new node, the rotating 6-digit TOTP code is used as the **password for a SPAKE2 (PAKE) handshake** — *not* as a bearer token verified by a seed-holder. A trusted node (online, no human needed — it holds the seed) computes the current code as its PAKE password; the user reads the code off their phone and types it into the new node. Matching codes → PAKE succeeds → pubkeys exchanged and bound, MITM-resistant encrypted channel established.\n\nWhy this construction (not plain TOTP-verification, not plain Magic Wormhole):\n- **Not TOTP-as-bearer-token** — a 6-digit code sent over the wire for verification is ~20 bits, replayable within its 30s window, and doesn't bind to the key being exchanged (real-time MITM/replay seam). PAKE makes the low-entropy code MITM-resistant and limits attackers to one online guess per attempt (no offline brute force).\n- **Better UX than plain Magic Wormhole** — Wormhole needs a fresh code on one node typed into the other, requiring a human/relay at *both* ends each pairing. With the persistent TOTP seed replicated to online trusted nodes, the trusted side is automatic; **the user only ever interacts with the new node** (read phone, type into new machine).\n\n**trust store**:\nEach node keeps a local store of authorized peer pubkeys. TOFU after pairing: accept on first connect post-ceremony, warn on key change. Lives near `node.key`.\n\n**link discovery (TOTP + name)**:\nThe TOTP code is **also the link-discovery selector**, not only the PAKE password — it routes the two not-yet-trusted nodes to the same pairing rendezvous over the relay's pairing ALPN. Because a 6-digit code is a weak global selector, discovery+link takes **two inputs: the TOTP code + the subnet-name** (the R-PAIR-4 human label), which namespaces the rendezvous. **The subnet-name is the second input in all cases** (the unified rule):\n- **join-existing** → enter the target subnet's name + its current code. Any online seed-holder of that subnet listens on that rendezvous and completes the PAKE; the joiner never enumerates the subnet's nodes.\n- **create-new** → the subnet is **named at creation**: one machine generates the new seed *and names the subnet* up front (becoming the sole seed-holder), then the joiner uses that subnet-name + the new seed's code. No node-name mode — naming simply happens at link start rather than after.\n\nThe name only namespaces the rendezvous; a collision (two unrelated pairings sharing a code + name) merely fails the PAKE (wrong password) — no security break, just a retry. **Rendezvous-token hashing (under the hood):** the relay routes the *pre-trust* pairing by a rendezvous token; the payload is already E2E-encrypted (R-NET-2), but the token itself is relay-visible, so spt-core derives it as `H(subnet-name ‖ TOTP-epoch)` rather than the plaintext label — the user/agent still enters the **raw name + code**, the hash is internal.\n\n**fetch-code-from-any-node (per-subnet, QR-optional)**:\nEvery node in a subnet holds that subnet's seed, so the user can fetch the *current* code for **any subnet the node belongs to** from any node in it — no phone required if a trusted node is handy. Because a node may be in several subnets (*subnet membership*), the fetch is **per-subnet**: CLI prompts *\"Show TOTP for which subnet? [subnet-1 … subnet-n | create new subnet]\"*, with **`--subnet <name>` / `--create-new`** flags to bypass the prompt (the agent-driven path). The code is offered optionally as a **QR / `otpauth://` URI** so the seed can be stored directly in an authenticator app (Google Authenticator etc.).\n\n**Node-bound code fetch is gated behind OS privilege elevation** (Windows UAC / Linux root-or-equivalent): retrieving a subnet's code *from the node* requires either hardware/elevated access OR an **elevated endpoint** (an agent whose process is elevated can surface it). This means the node-bound path proves real possession of the machine; everyone else falls back to **their own authenticator-app TOTP store** (where the seed was stored at pairing). The gate narrows the multi-subnet exposure — without elevation, mere CLI/agent presence on a node no longer yields *any* subnet's join-code; with it, node compromise still implies full trust loss for that node's subnets (unchanged baseline).\n\n**subnet naming**:\nThe first time two nodes pair, the user is prompted to **name the subnet**. The name is a human label on the subnet identity (which is cryptographically the shared seed). On every subsequent pairing the same name is shown (\"adding node to subnet `<name>`\"), giving the user confidence they're extending the right subnet as the fleet grows.\n\n**subnet icon** (GUI metadata): an optional small image (square PNG/WebP, ≤256 KB) representing the subnet in future GUIs. Stored **inline** in subnet metadata (so it syncs for free over the same subnet-material channel as the name; the cap keeps inline-sync trivial — it's an icon, not a media library), **editable by any node in the subnet, any time** (seeded at create/name). **GUI-only consumer** (frontend milestone); data distribution rides M4.\n\nDesign caveats (carried forward, none disqualifying): a seed-holder must be online + reachable by the untrusted new node at pairing time (relay allows pre-trust contact on a pairing ALPN); ±1 TOTP window tolerance; rate-limit handshake attempts; **recovery** = re-provision the QR from any still-trusted node (all hold the seed) — losing all nodes *and* the auth app makes the subnet unrecoverable (documented); **revocation** of a paired node is a separate trust-store delete (TOTP gates joining only).\n\n**local-link authentication**:\nCross-node traffic already rides Iroh (E2E-encrypted by node keypairs). The exposed surface is *same-node* channels where potentially-untrusted code touches SPT — a shell binary's HTTP/stdin/relay link, HTTP-to-harness-binary delivery. These require a **per-link handshake at `api bind` that establishes a link token + local-channel encryption**, required on every subsequent message — a local-link auth capability so other local processes can't inject into or read a link. Shell↔broker links specifically are encrypted + handshaked.\n\n**binary-trust disclosure (accepted risk)**:\nA shell binary is the least-trusted code in the system (3rd-party, runs on the user's node, agent-controllable) — but the same is true of harness binaries. The capability toolset bounds what an *agent* may ask; it does not sandbox what the *binary* may do with its OS permissions. Optional **shell-binary sandboxing** is deferred (gated like instantiate-anywhere/remote-exec). The baseline stance: **running any adapter or shell binary means trusting it — a disclosed, accepted risk for all spt-core users.**\n\n## Consent & security gates\n\nGates the high-risk cross-node capabilities. **Trust boundary:** everything is within *one user's own subnet* (their own TOTP-SPAKE2-paired, mutually-trusted nodes; cross-subnet is deferred). So consent is **not** stranger-authentication — it is guardrails against (1) an agent doing something surprising/destructive the user didn't want, (2) **runaway** (spawning instances / burning compute/billing across nodes), (3) **compromise containment** (limiting a compromised node/agent's cross-node blast radius).\n\n**Consent model — hybrid (grants + interactive escalation):**\n- **Grant store** — records `capability × subject (agent) × target (node)` (this granularity is sufficient; finer per-command-pattern scoping is a later refinement). **Enforced at the target node** (the node receiving a remote action checks its local grants), **settable subnet-wide** (a grant authored from any node propagates to the target), and **revocable**. Lives with subnet security material (near the trust store), not in the context git repo.\n- **Interactive escalation** — an ungranted high-risk action → the target node routes a **consent prompt to the user's most-recently-active session** (the registry-resolution precursor the update-prompt uses; PresenceChannel later generalizes it). Options: **allow-once / allow-always (writes a grant) / deny** — plus the harness's native free-text field (e.g. CC's AskUserQuestion \"Other\") for refinement.\n- **Pre-consent flags** — the shell `can_shutdown` and endpoint `shell_wake_spawn_anywhere` flags are simply grants authored ahead of time via manifest/endpoint settings (same model, different authoring path).\n\n**What is gated vs not:**\n- **Gated (default-deny, grant or prompt):** remote command execution (highest risk), instantiate-anywhere (spawn an endpoint on a remote node).\n- **Pre-consented by flag:** shell owner-shutdown, shell wake-spawn-anywhere.\n- **Ungated:** remote-drive of your *own running* instance (low risk — your own instance; a light \"node X is driving `ling@desktop`\" notification suffices), cross-node context/Psyche sync (your own data).\n\n**endpoint access whitelist** (distinct from the grant store — the outer reach gate):\nA per-endpoint allow-list controlling **who may remotely reach** an endpoint, **by origin node** (and, later, by user).

Here are my findings.\n\n---\n\n# Crate selection: TOTP-seeded SPAKE2 node pairing\n\n## Recommendation table\n\n| Concern | Crate | Version | Last release | Why | Risk |\n|---|---|---|---|---|---|\n| PAKE | `spake2` (RustCrypto) | **0.4.0** (stable) | 2023-07-28 | Only maintained pure-Rust SPAKE2; RustCrypto org (Arcieri + Warner); ~59k dl/mo; Ed25519Group + SHA-256/HKDF; binds both identities + both messages into final key | **No third-party audit** (self-declared). 0.4.0 pulls `curve25519-dalek = \"4\"` — version-compatible with your stack, but pin ≥4.1.3 (RUSTSEC-2024-0344). **No key-confirmation** — you must add it. |\n| TOTP | `totp-rs` (constantoine) | **5.7.1** | 2026-03-09 | Actively maintained (#11 Authentication, ~761k dl/mo); built-in `otpauth` URI + `qr` PNG + `gen_secret`; `hmac`+`sha1` per RFC 6238; exposes `sign(time)` (raw HMAC) | Raw step counter `T` is **not** a public method — see note below. SHA-1 default is RFC-correct, not a flaw. |\n| QR / provisioning | `qrcode` | **0.14.1** | 2024-07-05 | ~1.2M dl/mo; unicode terminal (`unicode::Dense1x2`) **and** PNG (via `image`); tiny, deps-light | Maintained but slow cadence. If you already take `totp-rs` with `qr`+`otpauth`, you may not need it standalone. |\n\n### Honorable mentions / alternatives\n- **PAKE alternatives**: No production-grade CPace crate exists in Rust; OPAQUE (`opaque-ke`) is heavier and solves augmented-PAKE (server stores no plaintext) — overkill for symmetric node pairing off a shared TOTP seed. `spake2` is the right pick. The newer `spake2 = 0.5.0-pre.0` (2026-01-25) bumps to `curve25519-dalek 5.0.0-pre.x` / `sha2 0.11` / `rand_core 0.10` — **do not use**: it would force a second, incompatible curve25519-dalek major into the tree alongside your ed25519-dalek v2 (which is on curve25519-dalek 4.x). Stay on `spake2 0.4.0`.\n- **TOTP alternatives**: `totp-lite` is leaner (just the code generator, no URI/QR) and `totp_rfc6238` exposes low-level APIs, but `totp-rs` already covers everything in one crate. Note that **none** of them expose the raw step counter as a value — same limitation everywhere.\n\n---\n\n## Critical answers\n\n**1. Does `spake2` bind identities/transcript, or do we layer our own MAC?**\nBoth — and you still need your own confirmation MAC.\n- It **does** bind the transcript into the derived key: `key = H( H(pw) ‖ H(idA) ‖ H(idB) ‖ X ‖ Y ‖ K )` where X/Y are both parties' messages. So identities + both pubkeys + password are already in the KDF.\n- It **does not** do key confirmation. `finish()` returns a raw shared-secret bytestring and nothing else; there is no confirmation-MAC exchange and no liveness check. The docs explicitly position the output as \"an HMAC key for subsequent messages.\" **You must add an explicit confirmation round** — and that's exactly where you bind your extra context (subnet ID, seed epoch, TOTP step), which `spake2` has no knowledge of.\n- Practical consequence: feed what `spake2` natively binds (roles via start_a/start_b, identities) through its `Identity`/`Password` inputs, and bind the rest (subnet ID, seed epoch, TOTP step counter) through your own HMAC-over-transcript confirmation on top of the raw shared secret. Belt-and-suspenders: also stuff subnet/epoch/step into the `Identity` strings so they're inside the PAKE KDF too, not only your outer MAC.\n\n**2. TOTP step counter exposure (the load-bearing TOTP question).**\n`totp-rs` does **not** expose `T` (= `time / step`) via any public method. It's computed inline inside `sign()`:\n```rust\npub fn sign(&amp;self, time: u64) -&gt; Vec&lt;u8&gt; {\n    self.algorithm.sign(self.secret.as_ref(), (time / self.step).to_be_bytes().as_ref())\n}\n```\n`next_step(time)` returns a **timestamp** (`(time/step + 1) * step`), not the counter. So to bind the step into your SPAKE2 transcript you compute it yourself: `let t_step = time / totp.step;`. This is trivial and deterministic — just don't expect the crate to hand you `T`. (This is true of every TOTP crate surveyed; flag accepted, roll the one-line division.)\n\n**3. RUSTSEC.**\n- No advisory against `spake2` itself.\n- `curve25519-dalek` has **RUSTSEC-2024-0344** (timing variability in `Scalar29/52::sub`), affecting **&lt; 4.1.3**, fixed in **4.1.3**. Since `spake2 0.4.0` requests `\"4\"`, your lockfile will resolve to ≥4.1.3 by default, but pin/audit it. This is the *same* curve25519-dalek 4.x major your `ed25519-dalek v2` already uses, so there is **no version conflict** — one shared curve25519-dalek 4.x in the tree.\n- `ed25519-dalek` had RUSTSEC-2022-0093 (Chalkias double-pubkey-oracle), fixed in v2 — you're already clear.\n\n---\n\n## API sketch — handshake + transcript-binding confirmation\n\n```rust\n// Dependencies (Cargo.toml):\n//   spake2   = \"0.4\"          # resolves curve25519-dalek 4.x (&gt;=4.1.3), sha2 0.10, hkdf 0.12\n//   totp-rs  = { version = \"5.7\", features = [\"otpauth\", \"qr\", \"gen_secret\"] }\n//   hmac     = \"0.12\"         # already implied by your sha2 0.10 stack\n//   sha2     = \"0.10\"\n//   subtle   = \"2\"            # constant-time compare for the confirmation tag\n\nuse spake2::{Ev = (), Spake2, Ed25519Group, Identity, Password};\nuse hmac::{Hmac, Mac};\nuse sha2::Sha256;\nuse subtle::ConstantTimeEq;\ntype HmacSha256 = Hmac&lt;Sha256&gt;;\n\n// ---- 0.

Derive the session key from the *confirmed* shared secret ----\nlet session_key = Hkdf::&lt;Sha256&gt;::new(Some(subnet), &amp;shared); // expand to taste\n```\n\n### Notes that matter for the build\n- **±1 window**: don't bake the step into the PAKE password and then try a ±1 window — a mismatched step changes the password AND the transcript, so verification just fails. Instead try the three candidate steps (`t_step-1, t_step, t_step+1`) as separate PAKE attempts, or agree the step out-of-band in the first message. Simplest robust design: dialer sends its `t_step` in the clear; both sides bind that exact value; reject if `|t_step_local - t_step_peer| &gt; 1`.\n- **Role pinning**: use `start_a`/`start_b` (asymmetric) for dialer/listener so roles are unambiguous; reserve `start_symmetric` only if you truly can't assign roles.\n- **Zeroize** `shared` and the TOTP secret after use (`totp-rs` has a `zeroize` feature; wrap `shared` in `zeroize::Zeroizing`).\n\nRelevant upstream sources: spake2 lib.rs (`C:` n/a — remote) https://github.com/RustCrypto/PAKEs/blob/master/spake2/src/lib.rs ; RUSTSEC-2024-0344 https://rustsec.org/advisories/RUSTSEC-2024-0344.html ; totp-rs https://github.com/constantoine/totp-rs ; qrcode https://docs.rs/qrcode .</result>\n<usage><subagent_tokens>42084</subagent_tokens><tool_uses>20</tool_uses><duration_ms>144893</duration_ms></usage>\n</task-notification>"}

Here are my findings.\n\n---\n\n# Crate selection: TOTP-seeded SPAKE2 node pairing\n\n## Recommendation table\n\n| Concern | Crate | Version | Last release | Why | Risk |\n|---|---|---|---|---|---|\n| PAKE | `spake2` (RustCrypto) | **0.4.0** (stable) | 2023-07-28 | Only maintained pure-Rust SPAKE2; RustCrypto org (Arcieri + Warner); ~59k dl/mo; Ed25519Group + SHA-256/HKDF; binds both identities + both messages into final key | **No third-party audit** (self-declared). 0.4.0 pulls `curve25519-dalek = \"4\"` — version-compatible with your stack, but pin ≥4.1.3 (RUSTSEC-2024-0344). **No key-confirmation** — you must add it. |\n| TOTP | `totp-rs` (constantoine) | **5.7.1** | 2026-03-09 | Actively maintained (#11 Authentication, ~761k dl/mo); built-in `otpauth` URI + `qr` PNG + `gen_secret`; `hmac`+`sha1` per RFC 6238; exposes `sign(time)` (raw HMAC) | Raw step counter `T` is **not** a public method — see note below. SHA-1 default is RFC-correct, not a flaw. |\n| QR / provisioning | `qrcode` | **0.14.1** | 2024-07-05 | ~1.2M dl/mo; unicode terminal (`unicode::Dense1x2`) **and** PNG (via `image`); tiny, deps-light | Maintained but slow cadence. If you already take `totp-rs` with `qr`+`otpauth`, you may not need it standalone. |\n\n### Honorable mentions / alternatives\n- **PAKE alternatives**: No production-grade CPace crate exists in Rust; OPAQUE (`opaque-ke`) is heavier and solves augmented-PAKE (server stores no plaintext) — overkill for symmetric node pairing off a shared TOTP seed. `spake2` is the right pick. The newer `spake2 = 0.5.0-pre.0` (2026-01-25) bumps to `curve25519-dalek 5.0.0-pre.x` / `sha2 0.11` / `rand_core 0.10` — **do not use**: it would force a second, incompatible curve25519-dalek major into the tree alongside your ed25519-dalek v2 (which is on curve25519-dalek 4.x). Stay on `spake2 0.4.0`.\n- **TOTP alternatives**: `totp-lite` is leaner (just the code generator, no URI/QR) and `totp_rfc6238` exposes low-level APIs, but `totp-rs` already covers everything in one crate. Note that **none** of them expose the raw step counter as a value — same limitation everywhere.\n\n---\n\n## Critical answers\n\n**1. Does `spake2` bind identities/transcript, or do we layer our own MAC?**\nBoth — and you still need your own confirmation MAC.\n- It **does** bind the transcript into the derived key: `key = H( H(pw) ‖ H(idA) ‖ H(idB) ‖ X ‖ Y ‖ K )` where X/Y are both parties' messages. So identities + both pubkeys + password are already in the KDF.\n- It **does not** do key confirmation. `finish()` returns a raw shared-secret bytestring and nothing else; there is no confirmation-MAC exchange and no liveness check. The docs explicitly position the output as \"an HMAC key for subsequent messages.\" **You must add an explicit confirmation round** — and that's exactly where you bind your extra context (subnet ID, seed epoch, TOTP step), which `spake2` has no knowledge of.\n- Practical consequence: feed what `spake2` natively binds (roles via start_a/start_b, identities) through its `Identity`/`Password` inputs, and bind the rest (subnet ID, seed epoch, TOTP step counter) through your own HMAC-over-transcript confirmation on top of the raw shared secret. Belt-and-suspenders: also stuff subnet/epoch/step into the `Identity` strings so they're inside the PAKE KDF too, not only your outer MAC.\n\n**2. TOTP step counter exposure (the load-bearing TOTP question).**\n`totp-rs` does **not** expose `T` (= `time / step`) via any public method. It's computed inline inside `sign()`:\n```rust\npub fn sign(&amp;self, time: u64) -&gt; Vec&lt;u8&gt; {\n    self.algorithm.sign(self.secret.as_ref(), (time / self.step).to_be_bytes().as_ref())\n}\n```\n`next_step(time)` returns a **timestamp** (`(time/step + 1) * step`), not the counter. So to bind the step into your SPAKE2 transcript you compute it yourself: `let t_step = time / totp.step;`. This is trivial and deterministic — just don't expect the crate to hand you `T`. (This is true of every TOTP crate surveyed; flag accepted, roll the one-line division.)\n\n**3. RUSTSEC.**\n- No advisory against `spake2` itself.\n- `curve25519-dalek` has **RUSTSEC-2024-0344** (timing variability in `Scalar29/52::sub`), affecting **&lt; 4.1.3**, fixed in **4.1.3**. Since `spake2 0.4.0` requests `\"4\"`, your lockfile will resolve to ≥4.1.3 by default, but pin/audit it. This is the *same* curve25519-dalek 4.x major your `ed25519-dalek v2` already uses, so there is **no version conflict** — one shared curve25519-dalek 4.x in the tree.\n- `ed25519-dalek` had RUSTSEC-2022-0093 (Chalkias double-pubkey-oracle), fixed in v2 — you're already clear.\n\n---\n\n## API sketch — handshake + transcript-binding confirmation\n\n```rust\n// Dependencies (Cargo.toml):\n//   spake2   = \"0.4\"          # resolves curve25519-dalek 4.x (&gt;=4.1.3), sha2 0.10, hkdf 0.12\n//   totp-rs  = { version = \"5.7\", features = [\"otpauth\", \"qr\", \"gen_secret\"] }\n//   hmac     = \"0.12\"         # already implied by your sha2 0.10 stack\n//   sha2     = \"0.10\"\n//   subtle   = \"2\"            # constant-time compare for the confirmation tag\n\nuse spake2::{Ev = (), Spake2, Ed25519Group, Identity, Password};\nuse hmac::{Hmac, Mac};\nuse sha2::Sha256;\nuse subtle::ConstantTimeEq;\ntype HmacSha256 = Hmac&lt;Sha256&gt;;\n\n// ---- 0. Provisioning side (operator scans QR once) ----\nlet totp = TOTP::new(Algorithm::SHA1, 6, 1, 30, Secret::generate_secret().to_bytes()?,\n                     Some(\"spt\".into()), node_label)?;\nlet uri  = totp.get_url();          // otpauth://...

Derive the PAKE password from the *current* TOTP code ----\n// Use the 6-digit code (or the raw sign() bytes) as the low-entropy PAKE password.\n// Compute the step ourselves (totp-rs doesn't expose it):\nlet now    = SystemTime::now().duration_since(UNIX_EPOCH)?.as_secs();\nlet t_step = now / totp.step;                  // &lt;-- the value to bind into the transcript\nlet code   = totp.generate(now);               // 6-digit string\nlet pw      = Password::new(code.as_bytes());\n\n// Bind structural context into the PAKE identities too (defense in depth):\nlet id_a = Identity::new(format!(\"spt:role=A;subnet={subnet};epoch={epoch};step={t_step}\").as_bytes());\nlet id_b = Identity::new(format!(\"spt:role=B;subnet={subnet};epoch={epoch};step={t_step}\").as_bytes());\n\n// ---- 2.

NO confirmation yet.\n\n// ---- 3. Explicit key confirmation (we add this; spake2 does not) ----\n// Confirmation MAC over roles + BOTH pubkeys + subnet + epoch + step, keyed by `shared`.\nfn confirm_tag(shared: &amp;[u8], role: &amp;[u8], my_msg: &amp;[u8], peer_msg: &amp;[u8],\n               subnet: &amp;[u8], epoch: u64, step: u64) -&gt; Vec&lt;u8&gt; {\n    let mut m = HmacSha256::new_from_slice(shared).expect(\"hmac key\");\n    m.update(b\"spt-pair-confirm-v1\");\n    m.update(role);\n    m.update(my_msg); m.update(peer_msg);     // bind both transcripts\n    m.update(subnet);\n    m.update(&amp;epoch.to_be_bytes());\n    m.update(&amp;step.to_be_bytes());            // TOTP step bound here\n    m.finalize().into_bytes().to_vec()\n}\n\nlet my_tag   = confirm_tag(&amp;shared, b\"A\", &amp;msg_a, &amp;msg_b, subnet, epoch, t_step);\n// send my_tag -&gt; B ; receive peer_tag (B's, computed with role=b\"B\", msgs swapped)\nlet want_peer = confirm_tag(&amp;shared, b\"B\", &amp;msg_b, &amp;msg_a, subnet, epoch, t_step);\nif peer_tag.ct_eq(&amp;want_peer).unwrap_u8() != 1 {  // constant-time compare\n    return Err(\"key confirmation failed — abort pairing\");\n}\n\n// ---- 4. Derive the session key from the *confirmed* shared secret ----\nlet session_key = Hkdf::&lt;Sha256&gt;::new(Some(subnet), &amp;shared); // expand to taste\n```\n\n### Notes that matter for the build\n- **±1 window**: don't bake the step into the PAKE password and then try a ±1 window — a mismatched step changes the password AND the transcript, so verification just fails. Instead try the three candidate steps (`t_step-1, t_step, t_step+1`) as separate PAKE attempts, or agree the step out-of-band in the first message.

RFC 6238 TOTP — the pairing ceremony's low-entropy shared secret (ADR-0005, D2a).\n//!\n//! The [`TotpSeed`] is the durable per-subnet secret (`CONTEXT.md` \"TOTP-seeded\n//! SPAKE2 pairing\"): generated on the first node, replicated to every trusted node,\n//! and provisioned into the user's authenticator app via an [`otpauth://`](TotpSeed::otpauth_uri)\n//! URI. The rotating 6-digit [`code_at`](TotpSeed::code_at) becomes the SPAKE2\n//! password — never a bearer token over the wire.\n//!\n//! ## Why roll RFC 6238 here instead of a TOTP crate\n//!\n//! The pairing transcript MUST bind the **raw time-step counter** `T` (= unix/period)\n//! so a stale-step pairing is rejectable (ADR-0005 #12). Every surveyed TOTP crate\n//! (`totp-rs`, `totp-lite`, …) hides `T` behind its code-string API — we'd recompute\n//! the division anyway. Rolling the ~RFC algorithm on the workspace's existing\n//! HMAC/SHA primitives keeps the step counter first-class, avoids a heavyweight\n//! dependency (URL/QR/image), and matches the crate's dependency-minimal convention.\n//! Verified against the RFC 6238 Appendix-B SHA-1 test vectors (see tests).\n//!\n//! ## ±1 window (ADR-0005 #11 interaction)\n//!\n//! Clock skew between the two pairing machines is absorbed by accepting the adjacent\n//! steps — but the step is **bound into the transcript**, not folded into the\n//! password (a changed step would change the password *and* the transcript, so a\n//! windowed retry can't work password-side). The dialer announces its step in the\n//! clear; both sides bind that exact value and reject `|Δstep| > 1`\n//! ([`accepts_step`]).

RFC 6238 TOTP — the pairing ceremony's low-entropy shared secret (ADR-0005, D2a).\n//!\n//! The [`TotpSeed`] is the durable per-subnet secret (`CONTEXT.md` \"TOTP-seeded\n//! SPAKE2 pairing\"): generated on the first node, replicated to every trusted node,\n//! and provisioned into the user's authenticator app via an [`otpauth://`](TotpSeed::otpauth_uri)\n//! URI. The rotating 6-digit [`code_at`](TotpSeed::code_at) becomes the SPAKE2\n//! password — never a bearer token over the wire.\n//!\n//! ## Why roll RFC 6238 here instead of a TOTP crate\n//!\n//! The pairing transcript MUST bind the **raw time-step counter** `T` (= unix/period)\n//! so a stale-step pairing is rejectable (ADR-0005 #12). Every surveyed TOTP crate\n//! (`totp-rs`, `totp-lite`, …) hides `T` behind its code-string API — we'd recompute\n//! the division anyway. Rolling the ~RFC algorithm on the workspace's existing\n//! HMAC/SHA primitives keeps the step counter first-class, avoids a heavyweight\n//! dependency (URL/QR/image), and matches the crate's dependency-minimal convention.\n//! Verified against the RFC 6238 Appendix-B SHA-1 test vectors (see tests).\n//!\n//! ## ±1 window (ADR-0005 #11 interaction)\n//!\n//! Clock skew between the two pairing machines is absorbed by accepting the adjacent\n//! steps — but the step is **bound into the transcript**, not folded into the\n//! password (a changed step would change the password *and* the transcript, so a\n//! windowed retry can't work password-side). The dialer announces its step in the\n//! clear; both sides bind that exact value and reject `|Δstep| > 1`\n//! ([`accepts_step`]). The ±1 widening of the valid-password space is the reason the\n//! ceremony also needs subnet-global rate limiting (D2d, #11).\n//\n// [impl->REQ-PAIR-1]\n\nuse hmac::{Hmac, Mac};\nuse sha1::Sha1;\nuse spt_proto::identity::Identity;\n\ntype HmacSha1 = Hmac<Sha1>;\n\n/// TOTP period in seconds (RFC 6238 default `X`). 30s is the authenticator-app norm.\npub const PERIOD_SECS: u64 = 30;\n\n/// Digits in a pairing code (RFC 6238 default). 6 is the authenticator-app norm; the\n/// PAKE — not the digit count — supplies the cryptographic strength (ADR-0005).\npub const DIGITS: u32 = 6;\n\n/// TOTP seed length in bytes. 160 bits = the RFC 4226/6238 recommended HMAC-SHA-1\n/// key size and what authenticator apps expect from a base32 `secret`.\npub const SEED_LEN: usize = 20;\n\n/// A subnet's durable TOTP seed — the shared secret behind the rotating code.\n///\n/// Held by every trusted node in the subnet and (via [`otpauth_uri`](Self::otpauth_uri))\n/// by the user's authenticator app. Stored near the node's trust material, never in\n/// the synced context repo.

Pairing transcript + key-confirmation MAC (ADR-0005 #12, D2b).\n//!\n//! SPAKE2 derives a shared key that already folds in the password and both parties'\n//! identities/messages — but it performs **no key confirmation** and knows nothing of\n//! *our* context (subnet, seed epoch, TOTP step). Stage-A red-team #12 is explicit:\n//! \"PAKE binds pubkeys *only if the transcript does*.\" Without an explicit\n//! confirmation that binds the full context, unknown-key-share, reflection, and\n//! wrong-subnet/stale-step pairings remain possible.\n//!\n//! This module is that binding: after the PAKE, each side computes an HMAC-SHA-256\n//! [confirmation tag](PairingTranscript::confirm_tag) keyed by the shared secret over\n//! the canonical transcript —\n//!\n//!   domain ‖ confirmer-role ‖ initiator_msg ‖ responder_msg ‖\n//!   subnet-name ‖ seed-epoch ‖ TOTP-step ‖ initiator_pubkey ‖ responder_pubkey\n//!\n//! — and verifies the peer's tag in constant time. A mismatch (wrong code, MITM,\n//! wrong subnet, stale step, swapped role) aborts pairing. Defense in depth: the same\n//! context is *also* fed into the PAKE [`Identity`](super::spake) strings, so it sits\n//! inside the KDF as well as the outer MAC.\n//!\n//! ## Why the joiner binds the subnet *name*, not the seed\n//!\n//! The joining node holds only the user-typed 6-digit code and the subnet name — it\n//! does **not** have the seed (only trusted seed-holders do). So the transcript's\n//! subnet identity is the human **name** both sides possess; knowledge of the seed is\n//! bound implicitly through the PAKE password (the code is derived from the seed). The\n//! [`epoch`](PairingTranscript::epoch) (responder-authoritative) binds *which* seed\n//! generation, closing the #10 rotation gap once D2c rotates it.\n//\n// [impl->REQ-HAZARD-PAIR-TRANSCRIPT-BIND] [impl->REQ-PAIR-1]\n\nuse hmac::{Hmac, Mac};\nuse sha2::Sha256;\nuse spt_proto::identity::PublicKey;\nuse subtle::ConstantTimeEq;\n\ntype HmacSha256 = Hmac<Sha256>;\n\n/// Domain separation tag — versioned so a future transcript-format change is a clean\n/// break, never a silent cross-version confusion.\nconst CONFIRM_DOMAIN: &[u8] = b\"spt-core/pairing/confirm/v1\";\n\n/// Length of a confirmation tag (HMAC-SHA-256 output).\npub const TAG_LEN: usize = 32;\n\n/// Which side of the ceremony a party plays.

Pairing transcript + key-confirmation MAC (ADR-0005 #12, D2b).\n//!\n//! SPAKE2 derives a shared key that already folds in the password and both parties'\n//! identities/messages — but it performs **no key confirmation** and knows nothing of\n//! *our* context (subnet, seed epoch, TOTP step). Stage-A red-team #12 is explicit:\n//! \"PAKE binds pubkeys *only if the transcript does*.\" Without an explicit\n//! confirmation that binds the full context, unknown-key-share, reflection, and\n//! wrong-subnet/stale-step pairings remain possible.\n//!\n//! This module is that binding: after the PAKE, each side computes an HMAC-SHA-256\n//! [confirmation tag](PairingTranscript::confirm_tag) keyed by the shared secret over\n//! the canonical transcript —\n//!\n//!   domain ‖ confirmer-role ‖ initiator_msg ‖ responder_msg ‖\n//!   subnet-name ‖ seed-epoch ‖ TOTP-step ‖ initiator_pubkey ‖ responder_pubkey\n//!\n//! — and verifies the peer's tag in constant time. A mismatch (wrong code, MITM,\n//! wrong subnet, stale step, swapped role) aborts pairing. Defense in depth: the same\n//! context is *also* fed into the PAKE [`Identity`](super::spake) strings, so it sits\n//! inside the KDF as well as the outer MAC.\n//!\n//! ## Why the joiner binds the subnet *name*, not the seed\n//!\n//! The joining node holds only the user-typed 6-digit code and the subnet name — it\n//! does **not** have the seed (only trusted seed-holders do). So the transcript's\n//! subnet identity is the human **name** both sides possess; knowledge of the seed is\n//! bound implicitly through the PAKE password (the code is derived from the seed).

The SPAKE2 pairing handshake state machine (ADR-0005, D2a/b).\n//!\n//! Wraps the `spake2` crate (RustCrypto, Ed25519 group) into the two role-typed flows\n//! of the ceremony, layering the [transcript confirmation](super::transcript) the PAKE\n//! itself omits. The TOTP [code](super::totp) is the PAKE password.\n//!\n//! ## The flow (initiator = joiner, responder = seed-holder)\n//!\n//! ```text\n//!   Initiator::start(transcript, code)          -> (Initiator, msg_a)         ──msg_a──▶\n//!

SPAKE2's `finish()` **does not fail on a wrong password** — it returns a *different*\n//! shared secret on each side. So a wrong code, a MITM, a wrong subnet, or a stale step\n//! all surface the same way: the [confirmation tags](super::transcript) don't match. The\n//! confirmation round is therefore not optional polish — it is the *only* thing that\n//! rejects a bad pairing.

The SPAKE2 pairing handshake state machine (ADR-0005, D2a/b).\n//!\n//! Wraps the `spake2` crate (RustCrypto, Ed25519 group) into the two role-typed flows\n//! of the ceremony, layering the [transcript confirmation](super::transcript) the PAKE\n//! itself omits. The TOTP [code](super::totp) is the PAKE password.\n//!\n//! ## The flow (initiator = joiner, responder = seed-holder)\n//!\n//! ```text\n//!   Initiator::start(transcript, code)          -> (Initiator, msg_a)         ──msg_a──▶\n//!

Two role-typed flows over the\n`spake2` crate (RustCrypto, Ed25519 group) with the TOTP code as the PAKE\npassword, plus the explicit key-confirmation SPAKE2 omits — the transcript\nbinding red-team #12 demands.\n\npairing::transcript — HMAC-SHA-256 confirmation MAC over the canonical\ntranscript: domain · confirmer-role · both SPAKE2 messages · subnet-name ·\nseed-epoch · TOTP-step · both node pubkeys, every variable field length-prefixed\n(no field-boundary forgery), verified with subtle::ct_eq (no timing oracle). The\nsame context is also folded into the SPAKE2 Identity strings — bound inside the\nKDF and in the outer MAC. The joiner binds the subnet *name* (it holds only the\ncode, not the seed); seed-knowledge is bound implicitly via the password, seed\n*generation* via the epoch (closes #10 once D2c rotates).\n\npairing::spake — Initiator (joiner, side A) / Responder (seed-holder, side B)\nstate machines. The load-bearing fact: SPAKE2 finish() does NOT error on a wrong\npassword — it yields a divergent key — so the confirmation round is the ONLY\nthing that rejects a bad pairing. Roles pinned to start_a/start_b so reflection\nis a PAKE BadSide. Shared secret wrapped in zeroize::Zeroizing; Paired redacts\nits key under Debug.\n\nNegative tests (all green): wrong-code, wrong-subnet, stale-step, stale-epoch,\nunknown-key-share (substituted pubkey), reflection, tampered-tag — plus the\nhappy path proving both sides agree on the key and learn each other's pubkey.\nTOTP verified against RFC 6238 Appendix-B vectors (D2a).\n\nActivates REQ-HAZARD-PAIR-TRANSCRIPT-BIND [impl,unit] (int = on-wire MITM/replay\nE2E at D9).

Sync therefore merges with **`--allow-unrelated-histories`** + the driver. History becomes a multi-parent DAG (one merge commit per sync) — cosmetic; periodic `git gc` keeps it tidy.\n101:**Scope:** hub mode is the **context-repo sync transport only.** Messaging, the subnet registry, remote-drive, pairing, and presence always ride P2P/Iroh — GitHub never carries real-time agent traffic, and gh-on never removes the P2P requirement.\n103:**Hub auth — shared deploy key.** The gh-authed setup node creates the private repo, generates a **read-write deploy key**, registers its public half on the repo, and distributes the **private half as subnet secret material** (via pairing / P2P, like the TOTP seed). Other nodes need **no GitHub account** — they use the deploy key over SSH. New-node linking never blocks (auto key + P2P backstop). Revocation = rotate the key (remove from repo, regenerate, redistribute) when a node is de-trusted or hub mode is disabled.\n109:- GitHub's published host key is pre-seeded into a scoped `known_hosts` (safer than blind `accept-new`).\n116:The `a-<id>` / `p-<project_id>` branch views are **linked git worktrees** off the bare seed repo. Linked worktrees store **absolute** back-links by default (`/home/<user>/…`, `C:\\Users\\<user>\\…`) → break on relocation, a different user account, or migration.

Sync therefore merges with **`--allow-unrelated-histories`** + the driver. History becomes a multi-parent DAG (one merge commit per sync) — cosmetic; periodic `git gc` keeps it tidy.\n101:**Scope:** hub mode is the **context-repo sync transport only.** Messaging, the subnet registry, remote-drive, pairing, and presence always ride P2P/Iroh — GitHub never carries real-time agent traffic, and gh-on never removes the P2P requirement.\n103:**Hub auth — shared deploy key.** The gh-authed setup node creates the private repo, generates a **read-write deploy key**, registers its public half on the repo, and distributes the **private half as subnet secret material** (via pairing / P2P, like the TOTP seed). Other nodes need **no GitHub account** — they use the deploy key over SSH. New-node linking never blocks (auto key + P2P backstop). Revocation = rotate the key (remove from repo, regenerate, redistribute) when a node is de-trusted or hub mode is disabled.\n109:- GitHub's published host key is pre-seeded into a scoped `known_hosts` (safer than blind `accept-new`).\n116:The `a-<id>` / `p-<project_id>` branch views are **linked git worktrees** off the bare seed repo.

A node belongs to *N* subnets (each cryptographically its own TOTP seed + trust\n//! context — `CONTEXT.md` \"subnet membership\"), so this one durable file under\n//! [`identity/`](crate::perch::identity_dir) holds a **collection** of\n//! [`SubnetRecord`]s, not a single subnet. Node-local, durable, **never git-tracked\n//! and never synced over the context repo** — it is subnet-joining secret material\n//! (it replicates only via the pairing/P2P channel, `docs/STORAGE.md`).\n//!\n//! ## Seed epoch + rotation (KNOWN-HAZARDS / ADR-0005 #10)\n//!\n//! Each record carries a monotonic [`epoch`](SubnetRecord::epoch). Stage-A red-team\n//! **#10**: *trust-store delete is not revocation* — the seed is replicated to every\n//! trusted node, so a compromised node can re-pair as a \"new\" node after a mere\n//! trust-store delete. The fix is [`rotate_seed`](SubnetStore::rotate_seed): removing\n//! a node **rotates the subnet seed and bumps the epoch**, so the old seed computes\n//! the wrong TOTP code and the [transcript](../../../spt_net/net/pairing/transcript)\n//! (which binds the epoch) rejects an old-epoch rejoin. The epoch is the\n//! responder-authoritative value the pairing ceremony binds.\n//!\n//! ## `(subnet, user)`-ready shape (cross-user seam)\n//!\n//! The optional [`user`](SubnetRecord::user) field is the forward seam for the\n//! cross-user model (`CONTEXT.md` \"Cross-user seam\"): v1 has one implicit user\n//! (`None`); when cross-user lands, the seed key generalizes to `(subnet, user)` with\n//! no re-architecture — force-unlinking a whole user's node-group becomes dropping\n//! that user's records.\n//\n// [impl->REQ-HAZARD-PAIR-SEED-ROTATION]\n\nuse serde::{Deserialize, Serialize};\nuse spt_proto::identity::Identity;\nuse std::path::Path;\n\nuse crate::atomic::atomic_write_string;\nuse crate::perch::subnet_file;\n\n/// TOTP seed length in bytes (160-bit, RFC 4226/6238).

A node belongs to *N* subnets (each cryptographically its own TOTP seed + trust\n//! context — `CONTEXT.md` \"subnet membership\"), so this one durable file under\n//! [`identity/`](crate::perch::identity_dir) holds a **collection** of\n//! [`SubnetRecord`]s, not a single subnet.

The fix is [`rotate_seed`](SubnetStore::rotate_seed): removing\n16\t//! a node **rotates the subnet seed and bumps the epoch**, so the old seed computes\n17\t//! the wrong TOTP code and the [transcript](../../../spt_net/net/pairing/transcript)\n18\t//!

Session shipped 3 commits (pushed bfacfb8..75f967c, CI running on the new crypto deps):\n\nD2a (56f2190) — pairing::totp: roll-own RFC 6238 TOTP (sha1+hmac+data-encoding), verified vs Appendix-B vectors; TotpSeed (CSPRNG via spt-proto RNG), base32, otpauth URI, raw time-step exposed for transcript bind, ±1 window. Also registered the 3 D2 hazard reqs up front (rule 3).\nD2b (597786e) — pairing::transcript + pairing::spake: spake2 0.4 (curve25519-dalek 4.1.3, shares ed25519-dalek v2's, no new major) + OUR HMAC-SHA256 confirmation MAC (spake2 does NO key-confirm). Transcript binds domain/role/both-msgs/subnet-name/epoch/step/both-pubkeys, length-prefixed, ct_eq. KEY FACT: SPAKE2 finish() does NOT error on wrong password — keys just diverge — so the confirm MAC is the ONLY rejecter. All negative tests green: wrong-code, wrong-subnet, stale-step, stale-epoch, unknown-key-share, reflection(BadSide), tampered-tag. Activated REQ-HAZARD-PAIR-TRANSCRIPT-BIND [impl,unit].\nD2c (75f967c) — spt-store::subnet: SubnetStore over identity/subnet.json, N per-subnet seeds (multi-subnet), monotonic epoch, (subnet,user)-ready. rotate_seed = node-removal revocation (#10): fresh seed + epoch bump; old seed/epoch can't rejoin (transcript binds epoch). Added perch::identity_dir/subnet_file/trust_dir resolvers. spt-net bridges via existing TotpSeed::from_bytes — no cycle. Activated REQ-HAZARD-PAIR-SEED-ROTATION [impl,unit].\n\nKEY FACTS for resume: pairing crypto core (TOTP+SPAKE2+transcript) DONE + fully unit-tested; what remains is glue. Joiner holds only the code, NOT the seed → transcript binds subnet-NAME (both have it); seed-knowledge bound via PAKE password, seed-generation via epoch. spt-store owns seed-bytes lifecycle; spt-net wraps for crypto (layering: spt-store below spt-net). Project has NO rustfmt gate in CI — do NOT `cargo fmt -p <crate>` (it reformats the whole crate incl pre-existing drift, polluting the commit); only my edited files.

If commands fail with \"command not found\", restart the Claude Code session so the SessionStart hook re-runs.\r\n\r\n> **Identity auto-detection:** Your identity is auto-detected from your session. Pass your ID explicitly only if auto-detection fails.\r\n\r\n## Flow\r\n\r\n1. **Download Psyche's *current* context** — it shifts during the session as background echo communes fire. Re-download right before composing; the gen-N snapshot you read at session start is already stale:\r\n   ```bash\r\n   $LIVE psyche-download <your-id>\r\n   ```\r\n\r\n   > **Output truncation.** If the Bash tool reports `Output too large (N KB)` and saves the full result to a `tool-results/<id>.txt` file, use the `Read` tool on that saved path to access the full content. Do NOT re-run `psyche-download` to grep/awk out sections — repeated invocations re-download the same context, waste tokens, and may duplicate `## Pending Commune` sections in `live_context.md`.\r\n\r\n2. **Diff your knowledge against this fresh download** — only what's missing from *it* is the real delta (new work, decisions, intentions). Anything already absorbed is not. If the download includes a `<memformat>` section, use it as a guide for what topics to cover. A `## Pending Commune (uncommitted)` section means a previous commune is still queued — do NOT re-send it.\r\n\r\n3. **Commune only the delta** -- use the **Write tool** to create\r\n   `.claude/{your-id}-commune.md` with the two-slice body as its contents\r\n   (see `## Two-slice body shape (Phase 25 D-10/D-11)` below for the required\r\n   envelope wrapping). Do not use Bash/heredoc -- Write is the canonical path:\r\n   no shell escaping, no `EOF` collision risk, and Write auto-creates the\r\n   `.claude/` parent directory.\r\n\r\n   Your Self listener detects the file on its next poll iteration, notifies\r\n   your Psyche wrapper, and the wrapper ingests the content via the existing\r\n   Psyche session. On success (subprocess exit code 0) the wrapper deletes the\r\n   file. On error (token rate limit, etc) the file is retained and retried on\r\n   the next consume cycle. If you write again before the wrapper consumes, the\r\n   latest write wins (last-write-wins overwrite semantics).\r\n\r\nIf Psyche's context is already current, no commune is needed. Say so and move on.\r\n\r\nRead `commune.md` (in this skill directory) for the full commune protocol -- when to send, what to include, and diligence triggers.\r\n\r\n**Agent-type guard:** Only works on live agents. If target is not live, refuses with: \"Communes require a live agent with Psyche.\"\r\n\r\n## Two-slice body shape (Phase 25 D-10/D-11)\r\n\r\nThe body you write in `.claude/{your-id}-commune.md` MUST itself be wrapped in two-slice envelopes per Phase 25 D-10/D-11. The taxonomy — what belongs in `<live-context>` vs `<project-context>` — is defined canonically in `psyche.md` §`<output_envelope>` (lines 282–323). Read that section as the source of truth; this skill doc teaches only when and how to apply it.\r\n\r\n**In-project detection rule (D-25.1-04).** Before composing your commune body, run `$LIVE psyche-download <your-id>` (Step 1 of `## Flow` above) and inspect the `<current ... />` tag at the top of the output. The `<current/>` tag carries a `project=\"...\"` attribute whenever any payload is produced — its presence means you are inside a tracked project (inside a git repo, `project` is the repo name; outside a git repo per D-11, `project` is the cwd-basename fallback, which still counts as a project context for routing purposes). A `psyche-download` invocation that returns no payload at all (NO-CONTEXT exit) means no project resolved. So: `project=\"...\"` populated on `<current/>` → emit BOTH envelopes (apply rule 1 or 2 below); no payload at all → emit ONLY `<live-context>` (rule 3). Secondary signal: the `<project-context-resolved name=\"...\"/>` sentinel further down the output indicates the project file already has prior content — useful for spotting first-time-in-project pairings, but NOT the routing rule.\r\n\r\n**Three rules (D-25.1-01..03):**\r\n\r\n- **In-project, both slices populated** (marker present, you have project-specific content this cycle): emit `<live-context>...</live-context>` AND `<project-context>...</project-context>`, both with non-empty bodies.\r\n- **In-project, no project-specific update this cycle** (marker present, but nothing project-bound to report): emit `<live-context>...</live-context>` AND `<project-context></project-context>` (empty body — the deliberate \"in-project but quiet\" signal per D-25.1-02). Distinguishable from \"no project resolved\".\r\n- **Outside any tracked project** (marker absent): emit ONLY `<live-context>...</live-context>`. Do NOT emit an empty `<project-context>` envelope (missing tag means \"no project resolved\" per D-25.1-03).\r\n\r\n**Nested envelopes.** The Phase 23 `<EVENT type=\"commune\">` envelope (see `## Envelope shape (Phase 23 v1.8)` below) is composed by `$LIVE commune` automatically — you NEVER write `<EVENT>` tags. You write ONLY the inner two-slice body. The two envelope layers nest: outer EVENT wraps inner two-slice body.\r\n\r\n(See `psyche.md` §`<output_envelope>` for the canonical taxonomy and per-slice content rules.)\r\n\r\n## Envelope shape (Phase 23 v1.8)\r\n\r\nAs of v1.8 Phase 23, commune deliveries are wrapped in a typed EVENT envelope carrying a 5-field stamp (`machine`, `project`, `branch`, `head_sha`, `head_subject`); the prose `COMMUNE (timestamp): body` form is gone.\r\n\r\n```xml\r\n<EVENT type=\"commune\" timestamp=\"2026-05-20T06:00:00-07:00\" machine=\"hostname\" project=\"claude_skill_owl\" branch=\"main\" head_sha=\"abc123...\" head_subject=\"subject line capped at 72 chars\">body</EVENT>\r\n```\r\n\r\nOutside a git repo (D-11), `branch`, `head_sha`, and `head_subject` are omitted entirely (not empty-string-set):\r\n\r\n```xml\r\n<EVENT type=\"commune\" timestamp=\"2026-05-20T06:00:00-07:00\" machine=\"hostname\" project=\"cwd-basename\">body</EVENT>\r\n```\r\n\r\n`$LIVE commune` composes this envelope automatically — Self does NOT manually construct EVENT XML. The `body` placeholder in the example above is the two-slice body (see `## Two-slice body shape (Phase 25 D-10/D-11)` above); the two envelope layers nest. The wrapper-side parser ignores unknown attrs, so the stamp fields are forward-compatible with older receivers. For drift detection on resume, see the `live` skill.\r\n\n\nARGUMENTS: M4-D2 pairing in progress. Session shipped 3 commits (pushed bfacfb8..75f967c, CI running on the new crypto deps):\n\nD2a (56f2190) — pairing::totp: roll-own RFC 6238 TOTP (sha1+hmac+data-encoding), verified vs Appendix-B vectors; TotpSeed (CSPRNG via spt-proto RNG), base32, otpauth URI, raw time-step exposed for transcript bind, ±1 window. Also registered the 3 D2 hazard reqs up front (rule 3).\nD2b (597786e) — pairing::transcript + pairing::spake: spake2 0.4 (curve25519-dalek 4.1.3, shares ed25519-dalek v2's, no new major) + OUR HMAC-SHA256 confirmation MAC (spake2 does NO key-confirm). Transcript binds domain/role/both-msgs/subnet-name/epoch/step/both-pubkeys, length-prefixed, ct_eq. KEY FACT: SPAKE2 finish() does NOT error on wrong password — keys just diverge — so the confirm MAC is the ONLY rejecter. All negative tests green: wrong-code, wrong-subnet, stale-step, stale-epoch, unknown-key-share, reflection(BadSide), tampered-tag. Activated REQ-HAZARD-PAIR-TRANSCRIPT-BIND [impl,unit].\nD2c (75f967c) — spt-store::subnet: SubnetStore over identity/subnet.json, N per-subnet seeds (multi-subnet), monotonic epoch, (subnet,user)-ready. rotate_seed = node-removal revocation (#10): fresh seed + epoch bump; old seed/epoch can't rejoin (transcript binds epoch). Added perch::identity_dir/subnet_file/trust_dir resolvers. spt-net bridges via existing TotpSeed::from_bytes — no cycle. Activated REQ-HAZARD-PAIR-SEED-ROTATION [impl,unit].\n\nKEY FACTS for resume: pairing crypto core (TOTP+SPAKE2+transcript) DONE + fully unit-tested; what remains is glue. Joiner holds only the code, NOT the seed → transcript binds subnet-NAME (both have it); seed-knowledge bound via PAKE password, seed-generation via epoch. spt-store owns seed-bytes lifecycle; spt-net wraps for crypto (layering: spt-store below spt-net). Project has NO rustfmt gate in CI — do NOT `cargo fmt -p <crate>` (it reformats the whole crate incl pre-existing drift, polluting the commit); only my edited files. CRLF warnings are benign.\n\nNEXT (in order): D2d subnet-global rate-limit (#11, REQ-HAZARD-PAIR-RATE-LIMIT) → D2e trust store TOFU+warn-on-change (REQ-PAIR-2, needs careful design: pubkey==iroh identity, re-read ADR-0009+registry) → D2-wire pairing ALPN driver over iroh bidi stream (4-msg ceremony, rendezvous H(name‖epoch), activates REQ-PAIR-1) → D2f/g multi-subnet ceremony + elevation-gated `spt pair show-totp` CLI (REQ-PAIR-3/4/5/6).

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: Resume M4-D2 pairing.
