# /spt:commune

All commands use `$LIVE` env var, auto-injected by the plugin's SessionStart hook. If commands fail with "command not found", restart the Claude Code session so the SessionStart hook re-runs.

> **Identity auto-detection:** Your identity is auto-detected from your session. Pass your ID explicitly only if auto-detection fails.

## Flow

1. **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:
   ```bash
   $LIVE psyche-download <your-id>
   ```

   > **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`.

2. **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.

3. **Commune only the delta** -- use the **Write tool** to create
   `.claude/{your-id}-commune.md` with the two-slice body as its contents
   (see `## Two-slice body shape (Phase 25 D-10/D-11)` below for the required
   envelope wrapping). Do not use Bash/heredoc -- Write is the canonical path:
   no shell escaping, no `EOF` collision risk, and Write auto-creates the
   `.claude/` parent directory.

   Your Self listener detects the file on its next poll iteration, notifies
   your Psyche wrapper, and the wrapper ingests the content via the existing
   Psyche session. On success (subprocess exit code 0) the wrapper deletes the
   file. On error (token rate limit, etc) the file is retained and retried on
   the next consume cycle. If you write again before the wrapper consumes, the
   latest write wins (last-write-wins overwrite semantics).

If Psyche's context is already current, no commune is needed. Say so and move on.

Read `commune.md` (in this skill directory) for the full commune protocol -- when to send, what to include, and diligence triggers.

**Agent-type guard:** Only works on live agents. If target is not live, refuses with: "Communes require a live agent with Psyche."

## Two-slice body shape (Phase 25 D-10/D-11)

The 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.

**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.

**Three rules (D-25.1-01..03):**

- **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.
- **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".
- **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).

**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.

(See `psyche.md` §`<output_envelope>` for the canonical taxonomy and per-slice content rules.)

## Envelope shape (Phase 23 v1.8)

As 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.

```xml
<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>
```

Outside a git repo (D-11), `branch`, `head_sha`, and `head_subject` are omitted entirely (not empty-string-set):

```xml
<EVENT type="commune" timestamp="2026-05-20T06:00:00-07:00" machine="hostname" project="cwd-basename">body</EVENT>
```

`$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.

Generation 46 → 47 complete. v0.13.0-delivery-control: **W1 deadlock fix fully banked** (`bab7d44` softening follow-up). cfg(unix) park-(b) assertion softened from FIXED to informational (tests green on Windows). All gates pass.

**W3 (bind-cwd surface discovery)** in progress: reading `establish_perch` + `cmd_bind`, mapping `InfoJson.cwd: Option<String>` (info.rs:77) + `Seed` struct + picker's project-grouping derivation from cwd.

**Pending:** W7 Backspace byte collection via `SPT_RC_DEBUG_KEYS` hexdump (user instructed to use fresh debug build: `target\debug\spt.exe`).

W3/W4/W5 queued. doyle approved (b)/(c) deferral to W2 per bounded deadline contract.

Test-engineer subagent (`spt-test-engineer.md`) registered as durable preference for future test writes.<project-context-resolved name="spt-core"/>
v0.12.2 release cycle remains suspended. v0.13.0-delivery-control delivery-control deadlock fix is load-bearing keystone (W1 architecture lock). W3 bind-cwd work now in discovery phase, no blocking on outside deliverables.

<live-context>
SESSION WIND-DOWN (resume next session). Delta since gen 47 (you knew: W1 banked, W3 in discovery, W7 byte pending):

**W7 — byte collected + fix LANDED, but HELD OPEN.** Operator captured pre-fix bytes (real WT, fresh debug bin): Backspace=0x08 (^H), Ctrl+Backspace=0x7f (DEL) = the inverted-from-VT signature (ENABLE_VIRTUAL_TERMINAL_INPUT OFF). Fix committed dc07c39: RawGuard enables VT input on the Windows stdin console + restores prior mode on drop (cfg(windows); with_vt_input = pure OR-in seam). unit green, clippy clean, traceable EXIT=0, KNOWN-HAZARDS 7.13 added. **DO NOT close W7** until doyle's operator re-capture confirms Backspace→0x7f on his CLEAN binary.

**LESSON (doyle caught, important):** `cargo test`/`cargo clippy -p spt` build the lib + TEST targets, NOT `target\debug\spt.exe`. My W7 "verified here" never rebuilt the installed binary → the operator would've re-captured the OLD bin. To verify/ship the real binary: `cargo build -p spt --bin spt` (and NEVER clobber a running daemon's spt.exe — Windows file lock; use daemon stop or the release path). doyle rebuilt dc07c39 in an ISOLATED git worktree (spt-w7verify) for the operator.

**LESSON 2 (doyle caught):** the shared working tree is shared with doyle/CI/operator. My uncommitted W3 impl-edit mid-flight briefly broke `cargo build -p spt` (E0061, transient between the establish_perch signature change and the call-site updates). Going forward: never leave the shared tree mid-edit — commit/park, or do WIP in a `git worktree`. (cfg(test)/tests/ edits ARE build-excluded = safe; only non-test impl mid-edit bites others.)

**W3 impl DONE (compiles), tests in flight.** establish_perch gained trailing `cwd: Option<&str>`; sets `rec.cwd = cwd.or_else(prior.cwd)` (revive carries forward). cmd_bind passes its own current_dir (broker spawned it in project_cwd); bind_from_seed passes seed.cwd (was discarded). Tagged [impl->REQ-HAZARD-BIND-CWD-UNSET]. NOT yet committed; REQ NOT yet activated (waiting on tests). The `spt-test-engineer` subagent (perch todlando-w166, NOW registered + available) is authoring the W3 unit + real-fixture int tests in the shared tree right now.

**Interactions:** doyle is the gate ("you build, I gate"); per-wave ping cadence. He gate-passed W1(a) on-machine. He added the W1-deferred Unix PTY-write bound to the W2 req (@66dadef). W1↔W5 SYNERGY: clear_controller IS W5's lost-controller unlatch — W5 is a thin "reconcile calls the same clear_controller" confirm.

**IMMEDIATE NEXT STEPS (resume order):**
1. Collect the spt-test-engineer W3 test output (subagent todlando-w166) → review → commit W3 impl+tests ATOMICALLY → activate REQ-HAZARD-BIND-CWD-UNSET [impl,unit,int] → `traceable-reqs check` → ping doyle to gate W3.
2. Await doyle's operator W7 re-capture (Backspace→0x7f) → THEN close W7.
3. W5 (thin, reuses clear_controller) — in a `git worktree`.
4. W4 (picker UX: open on Pick-existing/n=new, auto-attach after start+resume/h=headless, controlled-by = node NAME not hex, drop pid=Some() + internals leak; xtask gen if clap help changes; no REQ/M#-W# in /// help) — worktree.
5. ALL test authoring → the spt-test-engineer subagent (operator directive).

**v0.13.0-delivery-control — milestone status.** END GOAL: spt-hosted idle message delivery redesign (ADR-0022: an adapter `[message-idle-translation-binary]` — pure stdin→stdout filter, spt-core owns every PTY write + lifecycle) PLUS the control/wedge bug cluster fixed. Folds the suspended v0.12.2 work (window-fix @15fdf58, MD-sweep @2435a74, ATX @b3bb387) into the v0.13.0 release.

**Waves:** W0 design (doyle, ADR-0022, done). W1 KEYSTONE (controller-delivery wedge) = DONE + GATE-PASSED (8b5583e + bab7d44). W2 = the delivery redesign + the unified atomic PTY-write substrate (OWNS the deferred Unix park-(b)/(c) bound). W3 bind-cwd (impl done, tests in flight). W4 picker UX. W5 driven_by self-heal (thin, reuses W1 clear_controller). W6 perri builds the translation binary (after W2). W7 rc Backspace/VT-input (fix landed dc07c39, open pending re-capture).

**W1 architecture lock (load-bearing — do not regress):** controller output delivery is OFF the session drain thread — a dedicated controller writer thread + bounded channel (the viewer_writer pattern) does the blocking socket write; OutputLog::append hands each chunk to ControllerJob::deliver, a BOUNDED off-lock send (CONTROLLER_WRITE_DEADLINE=5s → clear_controller detach/unlatch, never park forever, never silent-evict a live operator). The controller is authoritative: its writer advances delivered_through (Arc<AtomicU64>, monotonic). Ring replay rides the writer's initial batch (subsumes the inline-replay block). Pre-fix bug: append wrote the controller INLINE on the drain thread holding Mutex<OutputLog> → a backed-up controller (slow operator / full 64KB rc loopback duplex under TUI redraw) wedged the whole session. KNOWN-HAZARDS 7.12.

**(b)/(c) facets:** input-side parks (write_input write_all on a full buffer; DSR-answer writer-mutex contention) are BENIGN on Windows ConPTY (absorbs a 4MiB inject), real only on Unix forkpty. Deferred to W2's atomic-write substrate (doyle ruling). The cfg(unix) repro assertion in inject_control_wedge.rs is INFORMATIONAL (gravity-linux CI is the observation venue) — W2 converts it to a real pre-fix assert once CI shows the park.

**Repro discipline (binding lesson, v0.12.0/.1):** every fix gated on a REAL dummy-harness fixture + real daemon, never mocks/theory. Repro-first: nail the mechanism before the fix; don't assert a bug you haven't reproduced.

Commune written to `.claude/todlando-commune.md` — your Self listener will ingest it next poll (both slices: live-context = wave/working state + the two doyle lessons; project-context = v0.13.0 milestone status + the W1 architecture lock + end goal).

## Session wind-down summary

**Banked this session:**
- **W1 keystone** — controller-delivery wedge fixed (off the drain thread, bounded deadline-detach), doyle gate-passed. `8b5583e` + `bab7d44`.
- **W7** — VT-input fix landed `dc07c39`; **held OPEN** pending doyle's operator re-capture on his clean isolated-worktree binary.
- **W3** — impl done + compiles; tests being authored by the `spt-test-engineer` subagent now.

**Resume next session (in the commune):**
1. Collect spt-test-engineer W3 output → commit W3 impl+tests atomically → activate REQ → traceable → ping doyle.
2. Await doyle's W7 re-capture → close W7.
3. W5 (thin, reuses `clear_controller`) + W4 (picker UX) — **in git worktrees** (doyle's shared-tree lesson).

**Two lessons captured:** `cargo test`/`clippy` ≠ rebuilding `target\debug\spt.exe` (use `cargo build -p spt --bin spt`, never clobber a running daemon's exe); never leave the shared tree mid-edit — commit/park/worktree.

⚠ Heads-up: the W3 `spt-test-engineer` subagent (perch `todlando-w166`) is **still running** in the background. Its edits are test-only (`cfg(test)`/`tests/`, build-excluded — main's `cargo build` stays green), but if the session ends now it may leave a partial test file to tidy next session. The W3 impl is uncommitted but compiles. Want me to wait for it to finish for a clean atomic commit, or are we pausing here?

<result>Done. All tests written, passing, and mutation-verified. No non-test code was touched (impl reverted byte-for-byte to its W3 form; `traceable-reqs.toml` untouched).

## Test code added

**Unit tests** — `crates/spt/src/api/startup.rs` (in the existing `#[cfg(test)] mod tests`):
- `bind_records_cwd_so_picker_can_group_by_project` (line ~793) — `[unit->REQ-HAZARD-BIND-CWD-UNSET]`: a spt-hosted `cmd_bind` sets `info.cwd` (non-None, == process `current_dir`) and the cwd-derived `project_id_for_dir` is non-empty.
- `revive_without_cwd_preserves_prior_cwd` (line ~820) — carry-forward guard: a re-bind via the seed path with `seed.cwd=None` must NOT wipe a previously-set cwd. Guards the `.or_else(prior.cwd)` branch.
- `seed_bind_records_seed_captured_cwd` (line ~847) — the harness-hosted seed path threads `seed.cwd` onto the perch (was discarded pre-W3).

**Integration test** — new file `crates/spt/tests/bind_cwd_project_e2e.rs`:
- `endpoint_run_records_cwd_and_appears_under_its_project` — `[int->REQ-HAZARD-BIND-CWD-UNSET]`: REAL detached `spt daemon run` + `endpoint run --start` dummy-harness bringup (verbatim setup from `dummy_harness_e2e.rs`); asserts the live perch's `read_info().cwd` is Some + non-empty, then asserts picker project membership via the public `spt_store` path (`project_id_for_dir` + the origin-union rule `local_rows` uses) — a fresh endpoint with no context appears under exactly `[origin project]`. All pids reaped scoped, bounded deadlines.

## Why the int test re-derives membership instead of calling the picker

`spt` is bin-only (no `[lib]`), so `picker::data::gather_endpoints` is unreachable from an integration test. The test asserts the equivalent over `spt_store` — the same data path the picker feeds from. The pure union rule itself is already unit-tested in `picker/data.rs::origin_project_unions_into_membership`; this test proves the REAL perch carries the cwd that rule consumes (the bug was the missing cwd, not the union logic).

## Commands

- Unit: `cargo test -p spt --bin spt startup::tests` → 14 passed (3 new + 11 existing)
- Int: `cargo build -p mock-adapter --bin mock-session` then `cargo test -p spt --test bind_cwd_project_e2e -- --test-threads=1` → 1 passed (~2.8s)
- Regression sanity: `cargo test -p spt --bin spt picker::data::tests` → 2 passed

## Mutation verification (proves the tests can fail)

- Broke impl to `rec.cwd = None` (pre-W3): all 3 new tests FAILED for the right reasons.
- Broke impl to drop `.or_else(prior.cwd)`: ONLY `revive_without_cwd_preserves_prior_cwd` failed; the SET and seed-thread tests still passed — confirming each test guards a distinct branch. Impl reverted to original after.

## Gaps left (intentional)

- No assertion on Windows backslash-vs-forward-slash normalization of the recorded cwd. `cmd_bind` records raw `current_dir()` (backslashes on Windows) while `bind_from_seed`/`cmd_seed` forward-slash-normalize. `project_id_for_dir` handles both, so it doesn't affect membership, but it's an inconsistency worth noting (see below) — not encoded as a test expectation.
- No flakiness observed across runs.

## Product observation (not a defect, surfaced separately)

Recorded cwd normalization is inconsistent by path: `cmd_seed` forward-slash-normalizes (`replace('\\', "/")`) but spt-hosted `cmd_bind` stores raw `current_dir()` (native backslashes on Windows). Both round-trip fine through `project_id_for_dir`, so no functional bug — but if anything ever string-compares `info.cwd` across the two bind paths, the slash style would differ. Flagging only; I did not encode either form as canonical in the tests (the int test asserts non-empty + project-id derivation, which is slash-agnostic).

</task-notification>


W3 subagent done — 3 unit + 1 int test, mutation-verified, impl untouched. (Noted the cwd slash inconsistency it flagged — harmless/slash-agnostic; the exact-equality unit test pins `cmd_bind` to raw `current_dir`, so normalizing is a separate follow-up, not wind-down churn.)

1	       Peer address seeding, both cold starts: durable peer-addrs.json (identity dir) maps peer pubkey → last-known dialable address; the pump's resolver consults it FIRST with id-only discovery fallback on miss or dial failure (a stale addr never strands a peer); written by the pairing ceremony (both sides, from the live connection) and by the pump on successful connect; post-join first sync and post-restart resync converge in seconds, not ~1 min (M8 decisions 14, 20)
2	       Net-bind boot-race resilience: a daemon that comes up net-less (NetHost::start failed — e.g. the systemd unit autostarted before the network/DNS stack was ready, `Failed to create an address lookup service`) must SELF-HEAL — retry the net bring-up in the background with capped backoff and, on success, attach net to the broker + spawn the dispatcher/peer-pump (which today are gated on `net_up` at boot and so never start, leaving the node silently unreachable until a manual restart — kitsubito 2026-06-08). Status surfaces the net-less state honestly (a net-less broker renders as 'no connection', not only a pump-STALLED line with a bogus pre-boot heartbeat age). The installer's autostart unit waits for the network (`Wants=/After=network-online.target`) as belt-and-suspenders.
3	       A legitimately dead PTY child (real crash/kill) + an undrained operator pump must NOT wedge the broker for all other clients. ROOT (v0.12.0 real-harness defect): loopback attach output is a blocking write_all into a bounded 64KB tokio duplex (nethost.rs:1040,1090); when the operator's rc pump stops draining (tab closed) the buffer fills and write_all blocks forever (the 'loopback never hangs' assumption at nethost.rs:1103 is false), parking a worker in the 2-worker net runtime (nethost.rs:640); a couple of these saturate BOTH workers → every new attach / `endpoint run` stalls right after 'PUMP_IPC_READER: spawned' → 30s FIRST_EVENT_GRACE → 'no output / dead or wedged'; `daemon stop` cannot join the stuck workers. DISTINCT from the removed B1 path-(c) mutex deadlock. DISPOSITION = PROVE-DON'T-CHANGE (doyle GATE-PASS @e883f45, 2026-06-18): this ROOT is the SUPERSEDED v0.12.0 hypothesis — the post-L0 code ALREADY prevents the wedge, so NO fail-fast / worker-count code was added. serve_attach forwards fire-and-forget (net_stream_send op_id=None) and the broker-side send_stream is already BROKER-QUIC-DEADLINE-bounded (bounded_block_on, 10s); the loopback duplex is drained broker-INTERNALLY by the operator row's own read pump (RecvHalf::Loopback, retentive_cap==0 → evict-not-park) so a dead rc (a dropped IPC subscriber) never backs peer_w up; bounded_block_on parks the BROKER DISPATCH thread, not a net worker → no worker-pool exhaustion (full mechanism in the required_stages comment). Folds the status=online sub-check: a dead spt-hosted endpoint is marked OFFLINE within one reconcile tick on abrupt child death (broker exit-waiter reaps the session → B2 sees it absent) — PROVEN, no change. (v0.12.1)
4	  [OK] REQ-HAZARD-BIND-CWD-UNSET  required: [impl, unit, int]  stages: -doc +impl +unit +int
5	       A bare brain restart leaves EXACTLY ONE `{id}-psyche` process per endpoint — no duplicate. On an abrupt brain death stop_host never runs (the LiveSet + owned child handles die with the brain) and Breap's job/group only reaps at DAEMON stop, so the PRIOR brain's Psyche stays ALIVE; the respawned brain's reconcile re-hosts a SECOND Psyche and overwrites the `{id}-psyche` perch pid, leaving the old one untracked + alive = a duplicate that lingers until daemon-stop (the operator's 'brain kill+restart wedged everything'). FIX: at brain start, BEFORE the first reconcile re-hosts, reap any pre-existing `{id}-psyche` orphan — ID-SPECIFICALLY (recycle-safe on the shared box, where sibling agents share the `claude` basename): scoped-kill the recorded pid ONLY IF it is alive AND its exe basename == the adapter's psyche program (normalize_basename) AND its COMMAND LINE contains the full psyche id `<id>-psyche` (baked via {id}); a sibling never carries THIS id, and any unreadable signal FAILS SAFE (decline to reap — a missed dup is bounded by Breap, a wrong-kill is catastrophic). CAVEAT: the cmdline carries `<id>-psyche` only when the adapter's psyche_init.command uses {id} (the norm); a non-{id} adapter safely MISSES the reap (today's behavior, Breap bounds it) — never a wrong-kill. (v0.12.0)
6	       The broker bounds every brain-waiting QUIC op (dial / open_stream / send_stream) so a black-holed or dead peer fails PROMPTLY with an ORDINARY error the broker REPLIES, never an unbounded await. The bound (< the brain's 30s PUMP_PEER_IO_TIMEOUT so the BROKER fires first) surfaces to the pump as a normal broker error reply → peer_outcome's non-TimedOut arm → drop conn + redial next tick, the round CONTINUES and the heartbeat keeps advancing — it must NEVER manifest as the brain's own read-deadline (the A-half poison → supervised-restart path REQ-HAZARD-PUMP-IPC-DEADLINE guards). Exactly-once is preserved: a timed-out journaled op fails INSIDE its apply_once closure so no phantom conn_id/stream_id is recorded and a fresh tick re-dials cleanly. The happy path is unchanged (a live peer completes with zero added latency; the bound only bites a non-responsive peer). This is the ROOT-cause cure for the 2.2h hfenduleam pump wedge — a dead roster peer whose QUIC path the broker awaited unbounded — recurring on hfenduleam 2026-06-16.
7	       A daemon-state wire-format change (e.g. the v0.9.0 adapter-agnostic Seed) does NOT take effect until a DELIBERATE full broker restart: the broker serves the seed-control channel and is RESIDENT across a brain-only self-update (ADR-0004 no-terminate-during-update forbids auto-killing it), so a NEW-version CLI talking to a still-resident OLD broker fails the seed handshake — the old broker cannot deserialize the new Seed (its formerly-required `adapter` field is gone) and drops the conn without an ack, which surfaces to the CLI as a raw UnexpectedEof 'failed to fill whole buffer'. spt-core must (a) surface an ACTIONABLE diagnostic on that seed-ack EOF (name the stale-broker cause + the `spt daemon stop` fix — the broker restarts on the next api call), never the cryptic io error; and (b) document the operational rule (a deliberate broker restart is required on any daemon-state wire change — NOT automatic) + the FORWARD discipline (daemon-state/Seed schema changes stay additive + serde-default so a resident OLD broker tolerates a NEW CLI across a brain-only update; note this would NOT have rescued 0.9.0 itself, since the old broker's `adapter` was a required field). perri PREP-4 FINDING 1 (v0.9.0 CLI vs stale 0.8.x broker).
8	       A surfaced concurrent context pair is durably preserved (both versions, tracked artifacts) until a strictly dominating write clears it; no reconcile failure path discards an unmerged version (6.6, ADR-0013)
9	       B3: `spt daemon stop` then an immediate `spt daemon start` does NOT race — stop fully completes before it returns. Today request_stop (seedmap.rs:240-255) returns on the KIND_STOPPING ack (sent seedmap.rs:174-176) BEFORE the seed socket unbinds, so a following is_running ping (daemon.rs:375) wins the exit window and start reports ALREADY_RUNNING (operator: daemon stop → STOPPED then start → ALREADY_RUNNING). FIX: unbind/stop-gate the seed socket BEFORE acking KIND_STOPPING, OR request_stop waits for a ping-to-fail before returning. Unit: stop then immediate is_running()==false. (v0.12.0)
10	       A pointer-mode (delegated / GhReleaseManaged) adapter whose binary/manifest is not yet extracted is reported with a CLEAR diagnostic, never silently dropped. Today such an adapter reads its manifest LIVE from source_dir (registry.rs manifest_dir ~146/149); a deferred / un-extracted install makes load_manifest fail → registered() (~410, filter_map(.ok())) SILENTLY DROPS the row → downstream ADAPTER_UNRESOLVED + a cryptic os-error-2 on `spt adapter use`. FIX: surface a clear diagnostic at the resolver + at `adapter use` (name the adapter + the deferred/missing-manifest cause + the fix), not a silent filter-drop and not a bare os-error-2; consider an eager manifest copy at register time so host_binaries survive before the binary download completes. doyle Finding A.

fix(bind): W3 — set info.cwd on bind so a fresh endpoint shows under its project

REQ-HAZARD-BIND-CWD-UNSET. ROOT (doyle RCA): info.cwd was NEVER set on bind,
so a freshly-created perch had an empty cwd and the picker could not group it
under its project — the v0.12.1 P1 ("a fresh agent appears under its own
project right away") that the changelog REFUTED. Delivered for real here.

Fix: establish_perch gained a trailing `cwd: Option<&str>` and sets
`rec.cwd = cwd.or_else(prior.cwd)` (a revive carries the prior cwd forward —
a re-bind must not wipe it). cmd_bind (spt-hosted) passes its own current_dir
(the broker spawned the bind subprocess in the project cwd, REQ-HOST-RUN-2);
bind_from_seed (harness-hosted) passes seed.cwd (captured at `api seed`,
previously DISCARDED). The picker (picker/data.rs) already keys project
membership off info.cwd via project_id_for_dir — once cwd is set, grouping works.

impl = api/startup.rs establish_perch/cmd_bind/bind_from_seed.
unit = bind_records_cwd_so_picker_can_group_by_project +
revive_without_cwd_preserves_prior_cwd + seed_bind_records_seed_captured_cwd
(each guards a distinct branch — mutation-verified: rec.cwd=None fails all 3,
dropping .or_else(prior.cwd) fails only the revive guard).
int = bind_cwd_project_e2e.rs (REAL detached daemon + endpoint run: the live
perch's read_info().cwd is Some+non-empty AND appears under its project via the
project_id_for_dir membership the picker consumes).
REQ activated [impl,unit,int]; traceable EXIT=0.

NOTE (follow-up, harmless): cmd_bind records raw current_dir (native slashes)
while cmd_seed forward-slash-normalizes — slash-agnostic through
project_id_for_dir, but worth unifying.

`rec.cwd = cwd.or_else(prior.cwd)` (a revive carries the prior cwd forward —
a re-bind must not wipe it). cmd_bind (spt-hosted) passes its own current_dir
(the broker spawned the bind subprocess in the project cwd, REQ-HOST-RUN-2);
bind_from_seed (harness-hosted) passes seed.cwd (captured at `api seed`,
previously DISCARDED). The picker (picker/data.rs) already keys project
membership off info.cwd via project_id_for_dir — once cwd is set, grouping works.

impl = api/startup.rs establish_perch/cmd_bind/bind_from_seed.
unit = bind_records_cwd_so_picker_can_group_by_project +
revive_without_cwd_preserves_prior_cwd + seed_bind_records_seed_captured_cwd
(each guards a distinct branch — mutation-verified: rec.cwd=None fails all 3,
dropping .or_else(prior.cwd) fails only the revive guard).
int = bind_cwd_project_e2e.rs (REAL detached daemon + endpoint run: the live
perch's read_info().cwd is Some+non-empty AND appears under its project via the
project_id_for_dir membership the picker consumes).
REQ activated [impl,unit,int]; traceable EXIT=0.

NOTE (follow-up, harmless): cmd_bind records raw current_dir (native slashes)
while cmd_seed forward-slash-normalizes — slash-agnostic through
project_id_for_dir, but worth unifying.

W3 UP — c4fae19, green, gate it. Tree is CLEAN now (committed atomically, no WIP bleed).

REQ-HAZARD-BIND-CWD-UNSET (your RCA, delivered): establish_perch gained a trailing cwd param, sets rec.cwd = cwd.or_else(prior.cwd) (revive carries forward); cmd_bind passes its own current_dir (broker spawned it in project_cwd); bind_from_seed passes seed.cwd (was discarded). Picker (data.rs) already groups on info.cwd via project_id_for_dir → grouping works once cwd is set. The refuted v0.12.1 P1, for real.

Verified: unit 3/3 (bind_records_cwd / revive_preserves_prior / seed_bind_records — mutation-verified, each guards a distinct branch); int bind_cwd_project_e2e.rs (REAL detached daemon + endpoint run: live perch read_info().cwd Some+non-empty AND appears under its project membership); cargo build -p spt --bin spt clean (real bin, not just test target); traceable EXIT=0, REQ [impl,unit,int]. Tests authored by the spt-test-engineer subagent.

FOLLOW-UP flagged (harmless): cmd_bind stores raw current_dir (native slashes) vs cmd_seed forward-slash-normalize — slash-agnostic through project_id_for_dir; worth unifying, not blocking.

Status: W1 banked, W3 up for gate, W7 OPEN (awaiting your operator re-capture on the clean binary). Session is winding down (operator pausing) — W5 (thin clear_controller reconcile-reuse) + W4 (picker UX) resume next session in git worktrees. Ping me the W7 re-capture result whenever; I'll close it next session.

SESSION WIND-DOWN (resume next session). Delta since gen 47 (you knew: W1 banked, W3 in discovery, W7 byte pending):

**W1** banked + gate-passed (8b5583e + bab7d44 softening).

**W7 — byte collected + fix LANDED (dc07c39), HELD OPEN.** Operator captured pre-fix: Backspace=0x08 (^H), Ctrl+Backspace=0x7f (DEL) = inverted-from-VT (ENABLE_VIRTUAL_TERMINAL_INPUT OFF). Fix: RawGuard enables VT input on the Windows stdin console + restores on drop (cfg(windows); with_vt_input = pure OR-in seam). unit/clippy/traceable green, KNOWN-HAZARDS 7.13. **DO NOT close W7** until doyle's operator re-capture confirms Backspace→0x7f on his CLEAN isolated-worktree binary.

**W3 — DONE + COMMITTED (c4fae19). Tree clean.** establish_perch gained trailing cwd param, rec.cwd = cwd.or_else(prior.cwd) (revive carries forward); cmd_bind→current_dir, bind_from_seed→seed.cwd (was discarded). 3 unit + 1 int (bind_cwd_project_e2e.rs), mutation-verified, traceable EXIT=0, REQ activated [impl,unit,int]. Tests authored by the spt-test-engineer subagent (now registered/available). Up for doyle gate. FOLLOW-UP: cmd_bind raw-slash vs cmd_seed forward-slash — slash-agnostic, unify later.

**TWO LESSONS (doyle caught — load-bearing):**
1. `cargo test`/`clippy -p spt` build the lib+TEST targets, NOT target\debug\spt.exe. To verify/ship the real binary: `cargo build -p spt --bin spt` (never clobber a running daemon's spt.exe — Windows lock; use daemon stop / release path).
2. The working tree is SHARED with doyle/CI/operator. Never leave it mid-edit — commit/park, or do WIP in a `git worktree`. (cfg(test)/tests/ edits are build-excluded = safe; only non-test impl mid-edit breaks others.)

**Interactions:** doyle = the gate ("you build, I gate"), per-wave ping. Gate-passed W1(a) on-machine; added the W1-deferred Unix PTY-write bound to the W2 req (@66dadef). W1↔W5 SYNERGY: clear_controller IS W5's lost-controller unlatch.

**IMMEDIATE NEXT STEPS (resume order):**
1. Await doyle's W3 gate (c4fae19) + his operator W7 re-capture (Backspace→0x7f) → close W7.
2. W5 (THIN: reconcile loop calls the SAME clear_controller for the non-deadline vanished-controller case — one shared unlatch path) — in a `git worktree`. doyle gates it as a thin confirm on W1.
3.

**v0.13.0-delivery-control — milestone status.** END GOAL: spt-hosted idle message delivery redesign (ADR-0022: an adapter `[message-idle-translation-binary]` — pure stdin→stdout filter, spt-core owns every PTY write + lifecycle) PLUS the control/wedge bug cluster fixed. Folds the suspended v0.12.2 work (window-fix @15fdf58, MD-sweep @2435a74, ATX @b3bb387) into the v0.13.0 release.

**Wave status:** W0 design (ADR-0022, done). W1 KEYSTONE controller-delivery wedge = DONE/GATE-PASSED. W2 = delivery redesign + the unified atomic PTY-write substrate (OWNS the deferred Unix park-(b)/(c) bound). W3 bind-cwd = DONE (c4fae19), up for gate. W4 picker UX. W5 driven_by self-heal (thin, reuses W1 clear_controller). W6 perri builds the translation binary (after W2). W7 rc Backspace/VT-input = fix landed (dc07c39), OPEN pending re-capture.

**W1 architecture lock (load-bearing — do not regress):** controller output delivery is OFF the session drain thread — a dedicated controller writer thread + bounded channel does the blocking socket write; OutputLog::append hands each chunk to ControllerJob::deliver (bounded off-lock send, CONTROLLER_WRITE_DEADLINE=5s → clear_controller detach/unlatch, never park, never silent-evict a live operator). Controller is authoritative: writer advances delivered_through (Arc<AtomicU64>, monotonic). Ring replay rides the writer's initial batch. Pre-fix bug: append wrote the controller INLINE on the drain thread holding Mutex<OutputLog> → a backed-up controller (slow operator / full 64KB rc loopback duplex under TUI redraw) wedged the whole session. KNOWN-HAZARDS 7.12.

**(b)/(c) facets:** input-side parks (write_input write_all on full buffer; DSR-answer writer-mutex contention) BENIGN on Windows ConPTY (absorbs 4MiB inject), real only on Unix forkpty. Deferred to W2's atomic-write substrate (doyle ruling). cfg(unix) repro assertion in inject_control_wedge.rs is INFORMATIONAL (gravity-linux CI = observation venue); W2 converts to a real pre-fix assert once CI shows the park.

**Repro discipline (binding):** every fix gated on a REAL dummy-harness fixture + real daemon, never mocks/theory; repro-first; don't assert a bug you haven't reproduced.

Communed (updated for W3-landed). Session ready to pause.

## Final state — clean wind-down

**Committed this session (branch `v0.13.0-delivery-control`):**
- `8b5583e` + `bab7d44` — **W1** controller-wedge fix (gate-passed)
- `dc07c39` — **W7** VT-input fix (open, awaiting re-capture)
- `f05566b` — W7 confirm-hexdump
- `c4fae19` — **W3** bind-cwd (impl + 3 unit + 1 int, mutation-verified)

**Working tree: clean.** No WIP bleed — main builds green for doyle/CI/operator.

**Resume next session (in the commune):**
1. doyle's W3 gate + W7 operator re-capture (Backspace→`0x7f`) → close W7
2. **W5** (thin, reuses `clear_controller`) — in a git worktree
3. **W4** (picker UX) — in a git worktree
4. Tests → `spt-test-engineer` subagent (now wired)

**Carried lessons:** `cargo build -p spt --bin spt` to verify the real binary (not `cargo test`); never leave the shared tree mid-edit (worktree WIP).

W3 subagent finished cleanly. doyle pinged for the W3 gate. Paused and reachable — pick up here next session.

doyle: **W7 GATE FAIL** — VT-input backfired (Windows Terminal → win32-input-mode, not xterm VT; broke ctrl-b detach + forwards 6-field key records to CC). His EARLIER ruling (VT not normalize) reversed by the real-terminal re-capture — exactly why we verify. New plan: revert the VT code, narrow-normalize `0x08→0x7f` in the raw pump. Leaving the broken fix committed = ctrl-b detach regression in the tree, so I'll land the fix now (not defer). Acking.


Bash

$OWL send doyle <<'EOF'
ACK W7 GATE FAIL — clean catch via the real-terminal re-capture. ENABLE_VIRTUAL_TERMINAL_INPUT → win32-input-mode on Windows Terminal (6-field ESC[Vk;Sc;Uc;Kd;Cs;Rc_ records), NOT legacy xterm VT — wrong lever. Two regressions confirmed: ctrl-b detach dead (0x02 wrapped, parse_stdin_chunk never sees raw DETACH_PREFIX) + win32-input-mode forwarded to CC's own ConPTY negotiation = garbage. This is exactly why repro-first on the real terminal matters; my unit/clippy "green" never exercised the live key path.

Landing the revert+narrow-normalize NOW (not deferring — the broken VT fix in-tree is a ctrl-b detach regression, worse than a clean pause):
1. Revert dc07c39's rc.rs code: RawGuard back to raw byte forwarding (ctrl-b works, Backspace back to raw 0x08). KEEP the SPT_RC_DEBUG_KEYS hexdump (f05566b) + KNOWN-HAZARDS 7.12 (W1, unrelated) + the W7 REQ structure — I'll forward-fix, not git-revert, so W1's 7.12 + the REQ aren't lost.
2. Narrow normalize in the forward path: a pure cfg(windows) seam maps lone 0x08 → 0x7f in spawn_stdin_reader AFTER parse_stdin_chunk (so 0x02 detach + every other byte untouched; raw byte pump, NOT crossterm event mode). Unix unchanged (already VT; mapping there would break real ctrl+h).
3. Accepted: Ctrl+Backspace stays 0x7f=char-delete (word-delete lost on the secondary key). Skipping the ctrl+w(0x17) upgrade for now — won't assume CC's word-delete binding without your/operator confirm; noting it as the optional follow-up.
4. Rewrite KNOWN-HAZARDS 7.13 for the normalize approach + the VT-backfire lesson; update the W7 REQ comment.

Will ping with the revert+normalize commit → you rebuild isolated + operator re-captures (expect Backspace→[7f], ctrl-b d detach works). W7 stays OPEN.
