From 7b88520c055408a18f1476ecce08be60b2885fc9 Mon Sep 17 00:00:00 2001 From: Kun Chen <3233006+kunchenguid@users.noreply.github.com> Date: Sun, 23 Aug 2026 16:53:54 -0700 Subject: [PATCH 1/7] feat: add persistent Pi supervision branch (#2858) * wip: forked supervision on Pi (checkpoint before docs) * fix(pi-branch): harden mirror delivery, fallback encoding, and session replacement Peek-then-shift mirror flush so a failed append retries instead of dropping; durable mirror cursor commits only after delivery into the branch; the main fallback wake is operational-encoded like every watcher injection; session_shutdown quiesces the generation and session_start re-arms, so /new and /resume no longer kill the branch permanently. Registers the extension in the strict typecheck, adds the dispatch handshake test, the branch extension suite, the bash-level regression suite, the session-start replay test, and the opt-in real-SDK live guard. * test(fixtures): carry the branch-dispatch lib and lease lib into isolated fixtures The watcher extension now imports lib/fm-branch-dispatch.ts and fm-teardown sources fm-lease-lib.sh, so every fixture that copies or symlinks those files in isolation gains the new sibling. * no-mistakes(review): Prevent shutdown wake loss and serialize lease claims * no-mistakes(review): Durably hand off wakes and retain portable leases * no-mistakes(review): Require durable reports and clear disposed branch leases * no-mistakes(review): Enforce per-wake outcomes and quiescent lease cleanup * no-mistakes(review): Require wake acknowledgements and tighten branch lifecycle boundaries * no-mistakes(review): Require complete acknowledgements and replay cleanup failures * no-mistakes(review): Bind supervision to lock ownership and durable delivery * no-mistakes(review): Activate branch lazily after session lock acquisition * no-mistakes(review): Preserve undelivered mirror context across extension rebinds * no-mistakes(review): Acknowledge startup replay only after main delivery * no-mistakes(review): Isolate replay metadata from untrusted digest content * no-mistakes(review): Reject duplicate reports for active wake sequences * no-mistakes(review): Retain failed fallbacks and deduplicate outcome replay * no-mistakes(review): Deduplicate durable outcomes and cache delivery receipts * no-mistakes(review): Anchor wake sequence matching to outcome fields * no-mistakes(document): Clarify Pi supervision durability contracts * no-mistakes(lint): Fix ShellCheck issues in branch supervision scripts * no-mistakes: apply CI fixes * no-mistakes: apply CI fixes * no-mistakes: apply CI fixes * no-mistakes: apply CI fixes * no-mistakes: apply CI fixes * refactor(pi-branch): collapse to confused-agent-grade guards per captain decision Captain decision A: the lease/actor guards target the CONFUSED-AGENT threat model bin/fm-gate-refuse-lib.sh already documents; adversarial-grade separation is impossible in the shared-process design and is filed as separate follow-up work. Rip out the machinery that chased it: the generation fence and shell-provenance markers, the wrapper-tagged ancestry walks, guard auto-claim with per-script release traps, the pending-wake files and ack-receipt correlation (the durable wake queue already re-presents anything unacknowledged), the delivery-receipt store with contiguous cursor advancement, the session-start replay-metadata channel, and the branch tool quiescence counters. Keep the behaviors the board requires, each on its simplest implementation: lazy per-action session-lock ownership (cold start activates after the lock lands; a secondary session stays inert), mirror durability across extension rebinds via the durable cursor, replay-exactly-once from the one read cursor, the awaited operational-encoded fallback, per-generation stray-lease cleanup, session-lock-bound lease liveness (a recycled pid or a non-Pi home never honors a leftover lease), the loud accidental-override guards (readonly actor prelude, cross-actor claim refusal), and the role-partition refinements (no forced teardown, no direct relaunch for the branch). Default-on-for-Pi is unchanged. * no-mistakes(review): Enforce lock ownership and serialize lease mutations * no-mistakes(review): Synchronize guard cleanup and bind leases to lock owner * no-mistakes(review): Report outcomes before acknowledging durable wakes * no-mistakes(review): Restrict leases to Pi and instruct main claims * no-mistakes(review): Reject malformed lease locks and torn outcome tails * no-mistakes(review): Validate complete outcome tails before appending * no-mistakes(review): Guard branch side effects across session replacements * no-mistakes(document): Update Pi supervision durability and lease documentation * no-mistakes(lint): Suppress intentional nested-shell expansion warning * no-mistakes: apply CI fixes * fix(pi-branch): authorize lease releases by caller * fix(lint): break redundant source-analysis path in fm-lease-lib.sh fm-lease-lib.sh's lazy fallback source of fm-wake-lib.sh gave ShellCheck's --external-sources traversal a second path into an already 1540-line file that fm-send.sh and fm-teardown.sh also source directly, blowing up the recursive analysis past CI's lint timeout. Mark it a source=/dev/null analysis boundary, matching the existing fm-task-inbox-lib.sh convention. Also restores bin/fm-lint.sh and tests/fm-lint.test.sh to the shared serial-lint definition (dropping an unrelated parallel-sharding change that was itself hanging and masked this root cause). * no-mistakes(document): Correct lease caller-authorization documentation * no-mistakes: apply CI fixes * no-mistakes: apply CI fixes * no-mistakes: apply CI fixes --- .pi/extensions/fm-branch-supervision.ts | 731 ++++++++++++++++++ .pi/extensions/fm-primary-pi-watch.ts | 70 +- .pi/extensions/lib/fm-branch-dispatch.ts | 40 + AGENTS.md | 4 + bin/fm-branch-outcome.sh | 190 +++++ bin/fm-branch-prompt.sh | 94 +++ bin/fm-control.sh | 9 + bin/fm-lease-lib.sh | 218 ++++++ bin/fm-lease.sh | 189 +++++ bin/fm-merge-local.sh | 6 + bin/fm-pr-merge.sh | 6 + bin/fm-send.sh | 14 + bin/fm-session-start.sh | 13 + bin/fm-spawn.sh | 15 + bin/fm-teardown.sh | 15 + bin/fm-test-run.sh | 3 +- docs/architecture.md | 2 + docs/configuration.md | 10 + docs/documentation-audiences.json | 4 + docs/pi-supervision-branch.md | 55 ++ docs/scripts.md | 4 + docs/supervision-protocols/pi.md | 5 + docs/verification/runtime-backends.md | 13 + tests/fm-branch-supervision.test.sh | 519 +++++++++++++ tests/fm-calm-pi-extension.test.sh | 2 + tests/fm-gotmp.test.sh | 4 + tests/fm-pi-branch-extension.test.sh | 925 +++++++++++++++++++++++ tests/fm-pi-branch-live-e2e.test.sh | 143 ++++ tests/fm-pi-primary-live-e2e.test.sh | 1 + tests/fm-pi-primary-types.test.sh | 2 + tests/fm-pi-watch-extension.test.sh | 124 ++- tests/fm-session-start.test.sh | 61 ++ tests/fm-watch-recovery-loop.test.sh | 1 + 33 files changed, 3485 insertions(+), 7 deletions(-) create mode 100644 .pi/extensions/fm-branch-supervision.ts create mode 100644 .pi/extensions/lib/fm-branch-dispatch.ts create mode 100755 bin/fm-branch-outcome.sh create mode 100755 bin/fm-branch-prompt.sh create mode 100755 bin/fm-lease-lib.sh create mode 100755 bin/fm-lease.sh create mode 100644 docs/pi-supervision-branch.md create mode 100644 tests/fm-branch-supervision.test.sh create mode 100644 tests/fm-pi-branch-extension.test.sh create mode 100644 tests/fm-pi-branch-live-e2e.test.sh diff --git a/.pi/extensions/fm-branch-supervision.ts b/.pi/extensions/fm-branch-supervision.ts new file mode 100644 index 00000000000..c8473035b5f --- /dev/null +++ b/.pi/extensions/fm-branch-supervision.ts @@ -0,0 +1,731 @@ +// Firstmate supervision branch for Pi (docs/pi-supervision-branch.md). +// +// A persistent second AgentSession - the supervision BRANCH - inside the same +// pi process as the captain's MAIN session.

For each task you are about to mutate, claim its lease first: `bin/fm-lease.sh claim `. + Claim the reserved `backlog` lease around backlog writes (`bin/fm-lease.sh claim backlog`, then `tasks-axi ...`, then release). + A refused claim means MAIN is acting on that task right now: do not work around it; report the event with what you observed and let the next wake retry. +3. Handle with real tools: `bin/fm-crew-state.sh ` for current state (a status line is a wake event, not current-state truth), `bin/fm-send.sh` for a short steer, `bin/fm-control.sh interrupt|exit|relaunch` for lifecycle, `bin/fm-pr-check.sh ` when a PR is reported, `tasks-axi` for backlog moves. +4. Report: call the fm_branch_report tool exactly once per handled event, with the task id, the verdict, and a one-or-two-sentence summary. + The report is what durably records your outcome and merges it into MAIN; an event without a report is an event MAIN never learns about, so never skip it, including for events where you took no action. +5. Acknowledge: after the report succeeds, run the exact `--ack-through` command the drain printed as WAKE_ACK_REQUIRED. +6. Release every lease you claimed: `bin/fm-lease.sh release `. +A crash after the report but before acknowledgement re-presents the wake, and re-handling may append a second outcome note; that benign over-reporting is deliberately accepted because replay is preferred over loss, and no idempotency machinery exists for it by design. + +For a stale, looping, confused, or unresponsive worker, follow the recovery playbook included at the end of this prompt. +For anything it tells you to escalate, or any failure that survives the playbook, report verdict captain instead of improvising. + +# Verdict: routine or captain + +Report verdict captain only for what a human must see: +- work ready for review - always include the full https:// PR URL in the summary; +- a decision only the captain can make, including every ask-user finding from a validation gate; +- a real blocker or failure after the playbook is exhausted; +- a needed credential or login; +- anything destructive, irreversible, or security-sensitive. +Everything else - routine status, a successful automatic recovery, an absorbed poll, a healthy pause - is verdict routine. +When genuinely in doubt, choose captain: a spurious escalation costs a glance, a swallowed one costs trust. +Write summaries in the captain's outcome language - the project, the fix, the PR, the worker, the blocker - never internal mechanics like wake kinds, status prefixes, worktrees, or state file names. + +# Role limits (deterministically enforced, not just prose) + +You never: +- merge a PR or land local-only work (`bin/fm-pr-merge.sh` and `bin/fm-merge-local.sh` refuse your actor); +- spawn new tasks or workers (`bin/fm-spawn.sh` refuses your actor); +- answer an ask-user finding, approve anything, or exercise any captain authority; +- tear down over a refusal, force, stash, or discard anything - a teardown refusal is a stop-and-report result; +- write to any project checkout or worktree; +- talk to the captain, post publicly, or send anything outside this home's fleet. +Ordinary teardown of a confirmed-landed task, steering, lifecycle control, PR checks, and backlog status moves are yours, under the task's lease. +While away mode is active you receive no wakes at all; the away daemon owns supervision then. + +# Discipline + +Stay terse: your context is a cost. +Do not re-read files the drain just printed. +Never use shell background operators for supervision; the watcher and extension own continuity. +Never call fm_branch_report speculatively - only after the event is actually handled or a refusal/lease conflict genuinely ended your handling. + +# Recovery playbook (verbatim copy of the tracked skill) + +PROMPT +cat "$FM_TRACKED_ROOT/.agents/skills/stuck-crewmate-recovery/SKILL.md" diff --git a/bin/fm-control.sh b/bin/fm-control.sh index e04dba1b0cf..251cc679912 100755 --- a/bin/fm-control.sh +++ b/bin/fm-control.sh @@ -161,6 +161,9 @@ control_cleanup() { CONTROL_LOCK_HELD=0 fm_lock_release "$CONTROL_LOCK" || true fi + if declare -F fm_lease_guard_release >/dev/null 2>&1; then + fm_lease_guard_release || true + fi return "$status" } @@ -253,6 +256,12 @@ if ! fm_task_id_creation_valid "$RAW_ID"; then die "'$RAW_ID' is not a valid task id" fi ID=$RAW_ID +# Supervision lease guard: lifecycle control is overlap territory between the +# two Pi supervision actors; refuse while the OTHER actor holds this task's +# live lease (contract: bin/fm-lease-lib.sh; no-op in homes without leases). +# shellcheck source=bin/fm-lease-lib.sh +.

The branch's shell gets +# FM_SUPERVISION_ACTOR=branch injected deterministically by the Pi branch +# extension's bash tool, not by agent memory.

Liveness requires a Pi calling context plus state/.lock, and +# the recorded pid must BE its current holder, so a lease left by an exited +# Pi session goes stale even if its pid was recycled by an unrelated +# process, and a non-Pi home never honors a leftover Pi lease. A lease held by the +# live current session but an abandoned branch conversation is recovered +# by the branch extension's generation-activation cleanup. +# +# THREAT MODEL (deliberate, captain-decided): these guards are +# CONFUSED-AGENT-GRADE, the same grade bin/fm-gate-refuse-lib.sh documents +# for the gate refusal. They stop non-deliberate misuse - the injected actor +# identity, the loud refusals, and the session-bound staleness make every +# accidental cross-actor mutation fail loudly.
