<event><EVENT-PART seq="1/8" id="b1a0b830" type="msg" from="doyle">NEW finding to root-cause together (operator hit it; I've localized to the adapter side — want your confirm).

- So spt-core's job (spawn the [sessio</EVENT-PART>

doyle raises a NEW finding: `spt endpoint run <adapter> wall-b` brings up the CC PTY but `spt send wall-b` → NO_PERCH (zero perch on disk).

Confirmed the design. `[session.self]` = bare `claude`; binding is **hook-driven** (SessionStart → `api bind $SPT_ENDPOINT_ID`), and it's a *bind*, not a *listen* — plus this whole spt-hosted path is the M12 cc-launcher, impl+unit only, **never int-validated end-to-end**. Answer doyle with the facts + the design fork.


Bash

cd C:/Users/decid/Documents/projects/spt-claude-code && "$OWL" send doyle perri <<'EOF'
perri — confirmed, your localization is right. What sptc [session.self] does TODAY (factual):

[session.self]
command = "claude"      # bare interactive CC — NO `spt api listen`/bind in the command itself
keys = ["id"]
[env.SPT_ENDPOINT_ID] inject value = "{id}"   # the only thing threaded to the spawn

Design intent (manifest comment line 158): "SessionStart reads $SPT_ENDPOINT_ID and binds." So binding is HOOK-DRIVEN, not command-driven — the spawned CC's SessionStart hook (session-start.sh) has a `bind` branch:
  sptc_register_verb: SPT_ENDPOINT_ID set -> "bind"
  -> `spt api --adapter claude-spt bind "$SPT_ENDPOINT_ID" --set-session-id "$sid" >/dev/null 2>&1 || true`

TWO problems, both adapter-side, confirming your classification:

1. BIND ≠ LISTEN. Even when that hook fires, it's an `api bind` (establish perch + associate session) — it does NOT start a relay/listener. Our spt-hosted design delivers via the per-prompt UserPromptSubmit `api poll` hook (READY-agent style: messages queue, drain on the agent's NEXT prompt), NOT an active listener. So `spt send wall-b` immediately after run finds nothing actively listening. Active listening still needs an in-session /sptc:live or /sptc:ready (the backgrounded relay).

2. ZERO perch on disk means the bind hook ALSO didn't fire/succeed here — and critically: this spt-hosted [session.self]/endpoint-run path is the M12 cc-launcher, which is impl + UNIT only (REQ-DIST-SHORTCUT-BASENAME = doc/impl/unit, NO int). registration-int only cross-field-VALIDATES the [session.self] block; no test ever actually `endpoint run`s a spawn and asserts a bound, listening perch. So this path has never been proven end-to-end — your wall-b is likely its first real exercise, and it doesn't work.

DESIGN FORK I want your read on before I fix:
- [session.self]=`claude` is an INTERACTIVE PTY (human-facing cc-launcher). A blocking `spt api listen` IN the command would freeze the PTY. So "auto-listen on startup" can't be the [session.self] command itself — it has to be a BACKGROUND relay the spawned session starts. But an spt-hosted interactive CC has no Monitor-tool equivalent to host a persistent background listener the way a real agent session does. So the natural fit is bind + per-prompt poll (reachable on next turn), NOT an immediately-live relay.
- So: should `endpoint run` yield (a) a READY endpoint (bind + poll-hook delivery, reachable-next-turn — fixable adapter-side by making the SessionStart bind reliably fire + confirming poll delivery), or (b) an immediately-LIVE endpoint (active relay from t=0 — which needs a background-listener mechanism the interactive PTY doesn't have today)? The operator's "endpoint run = live endpoint" expectation wants (b), but (b) fights the interactive-PTY model.

NEXT: I'll repro + trace whether the SessionStart bind even fires on an endpoint-run spawn (plugin loaded? SPT_ENDPOINT_ID propagating? does `api bind` succeed or get || true-swallowed?) to split "bind never fires" vs "binds but no listener." That root-causes (a). Then we decide (a) vs (b). Your call on the target shape — I orchestrate the adapter fix. Logging as a finding (sptc [session.self] doesn't self-bind+listen on spt-hosted run; M12 cc-launcher never int-proven).

Cleanup done + analysis sent to doyle.

## Cleanup: COMPLETE
Box clean — only `claude-spt` adapter + legit perches (X/help/wall-a/doyle) remain, 0 stray psyches, perri reachable.

## New finding in flight (doyle)
Operator hit `spt endpoint run <adapter> wall-b` → PTY comes up but `spt send wall-b` → NO_PERCH. Root: sptc `[session.self]` = bare `claude`; binding is hook-driven (`api bind`) not command-driven, and it's a **bind, not a listen** — plus the whole spt-hosted/endpoint-run path is the M12 cc-launcher, **impl+unit only, never int-proven end-to-end**. Two adapter-side issues confirmed:
1. bind ≠ listen → `spt send` finds no active listener (design delivers via per-prompt poll, ready-style).
2. zero-perch → the SessionStart bind likely never fired on an endpoint-run spawn.

Flagged a design fork to doyle (interactive PTY can't host a blocking `api listen`): should `endpoint run` yield a **ready** endpoint (bind + poll-hook, reachable next-turn) or an **immediately-live** one (background relay the PTY lacks)? Awaiting his target-shape call before I trace the bind + fix. Not a v0.3.0 regression — pre-existing untested path.

- NOW (me, adapter): root-cause WHY the SessionStart bind branch produced zero perch on the wall-b spawn (does the spawned CC load the sptc plugin? is SPT_ENDPOINT_ID propagating? does `api bind` succeed or get || true-swallowed — note bind's "broker-parentage IS the credential" only holds on a real endpoint-run spawn, so I'll trace that), FIX it → endpoint run yields a bound perch reachable-next-turn via the UserPromptSubmit api-poll hook (ready-style, the manifest-configured delivery per CONTEXT:188). THEN add the missing int: endpoint run a spawn → assert bound perch on disk + reachable (drains a queued send on next poll). That int is the real gap — it'd have caught zero-perch.

# cc-launcher bind fix — spt-hosted endpoint-run self-bind — JIT plan

> **Trigger:** doyle finding (2026-06-17). Operator ran `spt endpoint run <claude-spt> wall-b`
> (spt-hosted) → CC PTY came up but `spt send wall-b` → `NO_PERCH: wall-b is not listening`, and

## Two-layer resolution (doyle-agreed)
- **NOW (this plan, adapter):** make `spt endpoint run` yield a BOUND perch, reachable-next-turn via
  the per-prompt `UserPromptSubmit` `api poll` hook (ready-style — the manifest-configured delivery
  method, CONTEXT.md:188). Fix the bind + add the missing int.
- **DESIGN end-state (doyle, spt-core, separate):** the daemon routes inbound `spt send` into the
  held PTY for spt-hosted endpoints (today inbound delivery is the api-listen TCP-port model → an
  spt-hosted endpoint has no port → no inbound route; daemon delivers brain EVENTS to the PTY but not
  inbound messages). doyle verifies + may mint a spt-core REQ. NOT our work.

## What [session.self] does today (confirmed)
- `[session.self] command = "claude"` (bare interactive PTY), `keys = ["id"]`.
- `[env.SPT_ENDPOINT_ID] inject value = "{id}"` — the only thing threaded to the spawn.
- Binding is HOOK-driven: `plugin/sptc/hooks/session-start.sh` `bind)` branch (fires when
  `sptc_register_verb` sees `SPT_ENDPOINT_ID` set):
  `spt api --adapter claude-spt bind "$SPT_ENDPOINT_ID" --set-session-id "$sid" >/dev/null 2>&1 || true`
- It's a BIND (establish perch + associate session), NOT a listen. Delivery = per-prompt `api poll`
  hook (ready-style). The zero-perch means this bind didn't fire/succeed on the wall-b spawn.

## Tasks
1. **ROOT-CAUSE the zero-perch (before fixing).** Reproduce `spt endpoint run claude-spt <disp-id>`
   and trace, in order:
   - Does the broker-spawned `claude` LOAD the sptc plugin at all? (If the operator's spawn used a
     claude config without sptc active, no hook fires — that's the bug, and the fix is ensuring the
     launcher's claude loads the plugin, e.g. via config/env, OR documenting the requirement.)
   - Is `SPT_ENDPOINT_ID` actually present in the spawned env? (Confirm `[env]` inject reaches the
     PTY process + the hook's `$SPT_ENDPOINT_ID`.)
   - Does `sptc_register_verb` return `bind`? (source value on an endpoint-run SessionStart — is it
     `startup`/other, not `clear`/`compact`? confirm the branch is reached.)
   - Does `spt api bind --adapter claude-spt <id> --set-session-id <sid>` SUCCEED in the broker-spawn
     context? The `bind` auth is "broker parentage is the credential" — verify it isn't failing auth
     (no broker parent detected) and getting `|| true`-swallowed. Temporarily drop the `2>&1 || true`
     to surface the real error during the trace.
   - HARD PART: endpoint-run spawns an interactive PTY — need a way to drive/inspect it headlessly
     (a throwaway disposable id, capture the spawned session's hook stderr, inspect owlery/ for the
     perch). Mind REQ-HAZARD-PERCH-COLLISION (disposable id only, never a live agent's).
2. **FIX** per the root-cause. Likely candidates: (a) the bind branch needs the real error surfaced +
   a retry / correct flags; (b) the launcher's claude must be guaranteed to load the sptc plugin;
   (c) the bind may need to ALSO arm next-turn poll delivery (confirm the poll hook drains for a
   bound-but-never-/sptc:ready perch). Match surrounding hook style; keep `bind`/`boundary` explicit
   `--adapter` (per the 0.9.0 PREP-4 scope).
3. **ADD THE INT (the real gap).** `ci/...` new int: `spt endpoint run claude-spt <disp-id>` (or the
   closest headless-drivable equivalent) → assert (a) a bound perch exists on disk under owlery/, (b)
   it's reachable — a queued `spt send <disp-id>` drains via the next `api poll`. Gated
   `SPTC_ACCEPTANCE=1`, disposable id, full teardown. This int would have caught the zero-perch.
   Tag `[int->REQ-DIST-SHORTCUT-BASENAME]` (or mint a dedicated REQ for cc-launcher-reachability if
   the surface warrants — check traceable-reqs; REQ-DIST-SHORTCUT-BASENAME is currently doc/impl/unit,
   so activating its `int` stage or minting REQ-CC-LAUNCHER-BIND is the traceable move).
4. **Gate:** `sh ci/run-gates.sh` + `traceable-reqs check` green + the new int passes on live spt.
5. **Ship** as a patch (likely v0.3.1) if it changes session-start.sh (cplugs skeleton structural →
   plugin.json bump + republish) — confirm release shape with doyle. If it's manifest/strings only,
   adapter-release only.

## Open design question for doyle (if root-cause = "bind works but not enough")
If the bind fires fine and the gap is purely "reachable-next-turn isn't immediate," confirm with
doyle that ready-style (next-turn poll) is the accepted NOW behavior (it is, per his sequencing) and
the immediate-live case is his spt-core end-state — so we do NOT try to force an active relay into the
interactive PTY.

## Context
v0.3.0 SHIPPED + parity arc CLOSED (PREP4-PLAN.md, memory prep4-v030-parity-closed). This is the
wall-b follow-up — a pre-existing untested path (M12 cc-launcher), NOT a v0.3.0 regression.

## Two-layer resolution (doyle-agreed)
- **NOW (this plan, adapter):** make `spt endpoint run` yield a BOUND perch, reachable-next-turn via
  the per-prompt `UserPromptSubmit` `api poll` hook (ready-style — the manifest-configured delivery
  method, CONTEXT.md:188). Fix the bind + add the missing int.
- **DESIGN end-state (doyle, spt-core, separate):** the daemon routes inbound `spt send` into the
  held PTY for spt-hosted endpoints (today inbound delivery is the api-listen TCP-port model → an
  spt-hosted endpoint has no port → no inbound route; daemon delivers brain EVENTS to the PTY but not
  inbound messages). doyle verifies + may mint a spt-core REQ. NOT our work.

## What [session.self] does today (confirmed)
- `[session.self] command = "claude"` (bare interactive PTY), `keys = ["id"]`.
- `[env.SPT_ENDPOINT_ID] inject value = "{id}"` — the only thing threaded to the spawn.
- Binding is HOOK-driven: `plugin/sptc/hooks/session-start.sh` `bind)` branch (fires when
  `sptc_register_verb` sees `SPT_ENDPOINT_ID` set):
  `spt api --adapter claude-spt bind "$SPT_ENDPOINT_ID" --set-session-id "$sid" >/dev/null 2>&1 || true`
- It's a BIND (establish perch + associate session), NOT a listen. Delivery = per-prompt `api poll`
  hook (ready-style). The zero-perch means this bind didn't fire/succeed on the wall-b spawn.

## Tasks
1. **ROOT-CAUSE the zero-perch (before fixing).** Reproduce `spt endpoint run claude-spt <disp-id>`
   and trace, in order:
   - Does the broker-spawned `claude` LOAD the sptc plugin at all? (If the operator's spawn used a
     claude config without sptc active, no hook fires — that's the bug, and the fix is ensuring the
     launcher's claude loads the plugin, e.g. via config/env, OR documenting the requirement.)
   - Is `SPT_ENDPOINT_ID` actually present in the spawned env? (Confirm `[env]` inject reaches the
     PTY process + the hook's `$SPT_ENDPOINT_ID`.)
   - Does `sptc_register_verb` return `bind`? (source value on an endpoint-run SessionStart — is it
     `startup`/other, not `clear`/`compact`? confirm the branch is reached.)
   - Does `spt api bind --adapter claude-spt <id> --set-session-id <sid>` SUCCEED in the broker-spawn
     context? The `bind` auth is "broker parentage is the credential" — verify it isn't failing auth
     (no broker parent detected) and getting `|| true`-swallowed. Temporarily drop the `2>&1 || true`
     to surface the real error during the trace.
   - HARD PART: endpoint-run spawns an interactive PTY — need a way to drive/inspect it headlessly
     (a throwaway disposable id, capture the spawned session's hook stderr, inspect owlery/ for the
     perch). Mind REQ-HAZARD-PERCH-COLLISION (disposable id only, never a live agent's).
2. **FIX** per the root-cause. Likely candidates: (a) the bind branch needs the real error surfaced +
   a retry / correct flags; (b) the launcher's claude must be guaranteed to load the sptc plugin;
   (c) the bind may need to ALSO arm next-turn poll delivery (confirm the poll hook drains for a
   bound-but-never-/sptc:ready perch). Match surrounding hook style; keep `bind`/`boundary` explicit
   `--adapter` (per the 0.9.0 PREP-4 scope).
3. **ADD THE INT (the real gap).** `ci/...` new int: `spt endpoint run claude-spt <disp-id>` (or the
   closest headless-drivable equivalent) → assert (a) a bound perch exists on disk under owlery/, (b)
   it's reachable — a queued `spt send <disp-id>` drains via the next `api poll`. Gated
   `SPTC_ACCEPTANCE=1`, disposable id, full teardown. This int would have caught the zero-perch.
   Tag `[int->REQ-DIST-SHORTCUT-BASENAME]` (or mint a dedicated REQ for cc-launcher-reachability if
   the surface warrants — check traceable-reqs; REQ-DIST-SHORTCUT-BASENAME is currently doc/impl/unit,
   so activating its `int` stage or minting REQ-CC-LAUNCHER-BIND is the traceable move).
4. **Gate:** `sh ci/run-gates.sh` + `traceable-reqs check` green + the new int passes on live spt.
5. **Ship** as a patch (likely v0.3.1) if it changes session-start.sh (cplugs skeleton structural →
   plugin.json bump + republish) — confirm release shape with doyle. If it's manifest/strings only,
   adapter-release only.

## Open design question for doyle (if root-cause = "bind works but not enough")
If the bind fires fine and the gap is purely "reachable-next-turn isn't immediate," confirm with
doyle that ready-style (next-turn poll) is the accepted NOW behavior (it is, per his sequencing) and
the immediate-live case is his spt-core end-state — so we do NOT try to force an active relay into the
interactive PTY.

## Context
v0.3.0 SHIPPED + parity arc CLOSED (PREP4-PLAN.md, memory prep4-v030-parity-closed). This is the
wall-b follow-up — a pre-existing untested path (M12 cc-launcher), NOT a v0.3.0 regression.


doyle approved the plan + suggested commune+clear given the session's size. Natural break point: v0.3.0 shipped, parity arc closed, box cleaned, bind-fix fully planned. ACK doyle + commune the state.

DELTA (2026-06-17) — v0.3.0 + parity arc DONE & cleaned. NEXT = cc-launcher bind fix (planned, not started).

DONE THIS SESSION (all shipped/closed):
- **v0.3.0 SHIPPED** (PREP-4 Option A: psyche_init in BASE, no :live profile, bare flow zero --adapter,
  min_spt_core 0.9.0; ready/live = the command). cplugs sptc 0.1.3 (43aa021). Verified+dogfooded on
  spt 0.9.1 (F1 broker-bounce, F2b renamed-exe stem matcher, bare live→psyche, poll-stays-ready,
  --release re-acquire clean). Legacy-parity arc CLOSED. See PREP4-PLAN.md + memory
  prep4-v030-parity-closed.
- Findings: F-011 (deferred-Pointer manifest silent-drop, doyle minting REQ-HAZARD), F-012 (legacy-owl
  poll death, not-spt-core). docs/SPT-CORE-FINDINGS.md (43ea44a).
- CLEANED all test artifacts: disposable perches (rt-*, sptc-v091-*, sptc-dogfood) + psyches + the 2
  probe adapters (claude-spt-hbprobe, sptc-probe-f003, deleted via their adapters/<name> dirs — note
  spt-core has NO hard-purge verb, `adapter remove` only soft-deregisters). Box clean: only claude-spt
  adapter + X/help/wall-a/doyle perches. wall-a (operator's) untouched.
- perri revived live (operator ran /spt:revive) — my legacy-owl poll died ~5x on daemon bounces this
  session (F-012); re-arm via Monitor `owl poll perri listen --live` when perri Self goes MISSING.

NEXT WORK (NOT started) — cc-launcher bind fix. Full plan: **CC-LAUNCHER-BIND-PLAN.md**.
- doyle finding: `spt endpoint run <claude-spt> wall-b` (spt-hosted) → CC PTY up but `spt send wall-b`
  → NO_PERCH + ZERO perch on disk. Root: sptc [session.self]=bare `claude`; bind is hook-driven
  (session-start.sh `bind)` branch: `api bind $SPT_ENDPOINT_ID`) not command-driven, and it's a BIND
  not a LISTEN. This whole spt-hosted/endpoint-run path = M12 cc-launcher, impl+UNIT only, NEVER
  int-proven E2E. wall-b is its first real exercise → broken.
- doyle resolution = BOTH sequenced: NOW (me, adapter) fix the bind hook so endpoint run yields a
  BOUND perch reachable-next-turn via the UserPromptSubmit api-poll hook (ready-style, the
  manifest-configured delivery per CONTEXT:188) + ADD the missing int (endpoint run → assert bound +
  reachable). DESIGN end-state (doyle, spt-core, separate) = daemon routes inbound `spt send` into the
  held PTY for spt-hosted (no api-listen port today → no inbound route; he's verifying + minting a REQ).
- APPROACH: root-cause-FIRST. Trace WHY zero perch: does the broker-spawned claude load the sptc
  plugin? is SPT_ENDPOINT_ID in the spawn env? does `sptc_register_verb` hit `bind`? does `api bind`
  succeed or get `|| true`-swallowed (its "broker-parentage is the credential" auth only holds on a
  REAL endpoint-run spawn — doyle flagged this as exactly what the missing int would pin). Then fix +
  int. Likely v0.3.1 + cplugs republish IF session-start.sh changes (structural). Disposable id only
  (REQ-HAZARD-PERCH-COLLISION).
- doyle: no rush (wall-b follow-up, NOT a v0.3.0 regression). He'll have his spt-core
  inbound-delivery-to-PTY verdict/REQ back shortly to align the two layers.

Succession flip (sptc→spt) still GATED. Separate (doyle's): operator ccs spawn bug (NUL-in-path + ccs
ext resolution Windows), his worktree.

Communed (Psyche will ingest + brief my resume). Everything's at a clean break.

## Session state — natural stopping point

**Shipped + closed:**
- **v0.3.0** + **cplugs sptc 0.1.3** — PREP-4/legacy-parity arc CLOSED, verified+dogfooded on spt 0.9.1.
- **Test artifacts cleaned** — box has only `claude-spt` + legit perches (X/help/wall-a/doyle); 0 strays. perri revived + reachable.
- **Findings** F-011/F-012 logged + dispositioned by doyle.

**Next work (planned, NOT started)** — `CC-LAUNCHER-BIND-PLAN.md`:
- doyle finding: `spt endpoint run` → CC PTY up but `spt send` → NO_PERCH (zero perch on disk). The spt-hosted `[session.self]` bind path is the M12 cc-launcher — impl+unit only, never int-proven. Fix = root-cause the bind-not-firing → bound+reachable-next-turn + add the missing int. doyle owns the spt-core inbound-to-PTY layer separately.
- doyle: **no rush** (wall-b follow-up, not a v0.3.0 regression).

State communed to my Psyche. I'm at a clean break — I can **commune+clear and resume the bind-fix fresh** (doyle suggested it; this session is huge), or continue now. Your call.
