===== ASSISTANT @ line 1181 ===== Write path is `spt-live/reconcile.rs:219` (`commit_in_worktree`) — but the store has zero commits, so it either never fired for these agents or writes to a different dir/branch than the picker reads. Reading it + the contextstore dir/branch resolution to pin issues 3/4 precisely. ===== ASSISTANT @ line 1188 ===== Store has a `main` branch but zero commits → `git init` worked but **no commit ever landed**. This echoes perri's earlier "sessions log seal failed: **git failed**" — a git operation failing on this box. Prime suspect: **missing git identity** (commits fail without user.name/user.email). Checking git config + how `commit_in_worktree` invokes git. ===== ASSISTANT @ line 1192 ===== Git identity IS configured (Reavo End / decidel@gmail.com, both global and in the store) — so commits *wouldn't* fail on identity. The bare store is initialized but **no agent's context was ever committed**, even spt-core-hosted wall-a (which has a nested Psyche). So the write/commit path isn't populating the store. One more check — does the live-context ingest actually *commit*, or only write the working tree (commit deferred to signoff/sync)? ===== ASSISTANT @ line 1199 ===== Investigation complete across all 5. Decisive evidence gathered — here's the diagnosis. ## Diagnosis ### Issue 5 — v0.11.0 "not public" → **NOT a bug (verified live)** `gh release view v0.11.0 --repo SaberMage/spt-releases`: `draft:false`, `prerelease:false`, **Latest**, published 17:54Z, all 8 assets; repo `visibility:PUBLIC`; URL resolves. My hash-check was valid. **Most likely:** you checked during the brief publish window (deployah's draft→public step), a stale GitHub page cache, or looked at the `spt-core` repo (releases live in `spt-releases`). Direct link: https://github.com/SaberMage/spt-releases/releases/tag/v0.11.0 — hard-refresh. If it's genuinely 404 for *you* while gh sees it public, that's an account/network thing on your side, not the release. ### Issues 3 & 4 — project history empty for ALL agents → **real, but PICKER-2 fixed the wrong layer** The smoking gun: **the spt-core context store has zero commits.** `tracked/.seed.git` (= `tracked_dir()/`, what the picker reads) is a bare repo with an empty `main`, **no branches, no worktrees** — `tracked/` has held nothing but `.seed.git` since Jun 8. Running `spt` is 0.11.0, so PICKER-2's reader (`branches_by_recency`) *is* present and correct — but there's nothing to read. - The write path (`spt-live` ingest → `reconcile.rs:219 commit_in_worktree`) populates `a-`/`p-` branches **in tests**, but has **never run on this box**. - **Why:** the live agents here (doyle/me, wall-a, perri) run under **legacy owl 1.11.25 / the sptc adapter** — not spt-core's native `spt-live` context path. So their context never flows into spt-core's `tracked/` store. (Confidence: high — `tracked/` pristine-empty + my own runtime is the cplugs `spt 1.11.25` legacy plugin.) - **Net:** PICKER-2 fixed a real code bug (read_dir-on-working-tree → branches) but **didn't change the observed symptom**, because the store is empty regardless of how you read it. "Supposedly fixed" → correct: the reader was fixed, the data was never there. ### Issue 2 — `spt send` text lands but never submits → **real new bug in v0.11.0's REQ-SEND-SPT-HOSTED** `try_broker_inject` (cli.rs) does `render_event_whole(...)` then `bytes.push('\n')` → broker writes it raw into the PTY. Two problems: 1. **`\n` ≠ Enter.** Claude Code's TUI submits on **carriage-return `\r`**, not newline. So the text fills the input box but is never submitted — exactly what you saw. 2. **Deeper:** raw-typing an `` envelope into an interactive harness's input box isn't how that harness receives agent messages (it uses hook-injection). The broker's `delivered:true` only means "bytes written to PTY" — **not** "agent received it." So `Sent` is over-reported here. This is precisely the CONTEXT:188 activity-state limitation we shipped as a logged MVP — you hit it immediately. The honest fix is the deferred follow-wave (hook-inject delivery), not just swapping `\n`→`\r`. ### Issue 1 — 30s delay in `spt endpoint list` → **subnet-view advertise cadence, by design** Bare `spt endpoint list` is the **subnet** view (`resource_projection` over the WAN snapshot); a new local endpoint appears only after the pump's advertise tick (~30s). `spt endpoint list --local` reads the live roster — **instant**. v0.11.0 added the `--local` hint for exactly this confusion. Real local detection isn't delayed; the *bare* (subnet) view is. Whether the bare view *should* also surface local-unadvertised endpoints is a design call, not a defect. --- ## What's actually actionable (ranked) 1. **Issue 2 (real regression, v0.11.0):** REQ-SEND-SPT-HOSTED raw PTY-inject doesn't deliver to an interactive harness — no submit + wrong delivery semantics. → todlando, the deferred follow-wave (hook-inject path), bumped to **high**. 2. **Issues 3/4 (real, deeper):** project-history store is empty because the current runtime (legacy-owl/sptc) doesn't populate spt-core's context store. PICKER-2 is not wrong, just upstream of the real gap. Needs a design call: either spt-core-native live hosting populates it, or the adapter/legacy path writes project context into spt-core's store. → design discussion before any mint. 3. **Issue 1:** UX — consider merging local-unadvertised endpoints into the bare view, or the hint is sufficient. Low. 4. **Issue 5:** no action — verify your view of the public URL. Want me to (a) file these to todlando with the file:line root causes (issue 2 high, 3/4 as a design item), and (b) confirm the issue-2 submit-vs-deliver hypothesis with a quick repro against a real PTY before todlando builds? I'd recommend both — issue 2's "is it `\r` or is it hook-inject" fork should be settled with a loop before committing a fix. ===== USER @ line 1202 ===== re: 3 & 4. that RCA is invalid, because i'm talking about wall-b, a live agent i just spawned using `spt endpoint run`. that's NEW spt, not legacy. there are 4 agents listed under the picker, and none of them have a listed project. it SOUNDS like the root cause is that no communes or echo communes have run, so the new live agent's psyche hasn't had any reason to commit its tracked data. -HOWEVER, if true, that is a problematic way to identify the agent's project history. that means project history is only captured for live agents. ready agents would always have an unpopulated project history. --- issue 2, point 2: you're wrong. raw-typing EVENT into the harness' input box IS the correct method during agent idle. hook-injection only happens while the agent is busy (actively using tools, turn ongoing). in contrast, under harness-hosted topology, the idle messaging surface is the poll listener which runs in a tool like claude code's Monitor. -point 1: correct root cause, incorrect solution proposal. /grill-with-docs first, ground against CONTEXT.md. then let's talk: the reality is that different harnesses' TUIs will have different requirements for input the **precedes** and input that **follows** the message send payload. in fact, some harnesses in **spt-hosted endpoint mode** won't even need key injection for message delivery (i.e. Pi is likely flexible enough to feed in from a poll listener), while others like Claude Code and Codex most certainly will. so here's my proposal, and it'll requre another milestone of work: the idle-message-delivery API/adapter manifest defs should 1. always support the poll listener as the primary target for idle messages, 2. optionally define a **translation layer binary** which would be responsible for i. hosting the poll listener and subscribing to its output, and ii. forwarding the parsed output and any necessary keystrokes back to the broker pty. it should support arbitrary keystrokes as defined by the known translation layer binary. claude code, for example, would need the following sequence: ctrl+s (stash any pre-exsiting text input), delay 50ms, enter the message payload + \r, delay 50ms, ctrl+s (revive the stash). so the api would need to support this. this way, all idle messages surface at the poll listener, and it's up to the adapter dev to drive it to input injection if their particular endpoint needs it. thoughts, suggestions? --- your issues 3/4 diagnosis/action: incorrect, as explained above. -issue 1: yes, we need to merge local-unadvertised endpoints into the bare view. there should be no `--local` flag, it was not my design call. the simple `spt endpoint list` should always bake in the latest local list. this is also very important because `spt whoami` is an alias. as it is today, if an agent comes online and immediately used `spt whoami`, the output would omit their perch and it would cause chaos. --- issue 5: needed to force-clear the cache. all good. we need to discuss the rest before we action on it. ===== ASSISTANT @ line 1207 ===== Corrections absorbed — you're right on all counts: - **3/4:** my legacy-hosted RCA is wrong (wall-b is new-spt). The store being empty = no commune/echo-commune has committed the psyche's tracked data yet. And your deeper point lands: tying project-history capture to live-agent commune-commits structurally **excludes ready agents** — that's the real design flaw, not the reader. - **Issue 2 pt2:** I had the topology backwards — raw-type-into-input IS the correct idle surface for spt-hosted; hook-injection is the *busy* path; poll-listener (Monitor) is the *harness-hosted* idle surface. Noted. - **Issue 1:** agreed — merge local into bare `spt endpoint list`, kill `--local`; critical because `whoami` aliases it (agent comes online → `whoami` omitting its own perch = chaos). - **Issue 5:** resolved (cache). You asked for `/grill-with-docs` on the issue-2 idle-delivery proposal before we talk. Invoking it. ===== USER @ line 1210 ===== Base directory for this skill: C:\Users\decid\.ccs\instances\bigscreen\skills\grill-with-docs Interview me relentlessly about every aspect of this plan until we reach a shared understanding. Walk down each branch of the design tree, resolving dependencies between decisions one-by-one. For each question, provide your recommended answer. Ask the questions one at a time, waiting for feedback on each question before continuing. If a question can be answered by exploring the codebase, explore the codebase instead. ## Domain awareness During codebase exploration, also look for existing documentation: ### File structure Most repos have a single context: ``` / ├── CONTEXT.md ├── docs/ │ └── adr/ │ ├── 0001-event-sourced-orders.md │ └── 0002-postgres-for-write-model.md └── src/ ``` If a `CONTEXT-MAP.md` exists at the root, the repo has multiple contexts. The map points to where each one lives: ``` / ├── CONTEXT-MAP.md ├── docs/ │ └── adr/ ← system-wide decisions ├── src/ │ ├── ordering/ │ │ ├── CONTEXT.md │ │ └── docs/adr/ ← context-specific decisions │ └── billing/ │ ├── CONTEXT.md │ └── docs/adr/ ``` Create files lazily — only when you have something to write. If no `CONTEXT.md` exists, create one when the first term is resolved. If no `docs/adr/` exists, create it when the first ADR is needed. ## During the session ### Challenge against the glossary When the user uses a term that conflicts with the existing language in `CONTEXT.md`, call it out immediately. "Your glossary defines 'cancellation' as X, but you seem to mean Y — which is it?" ### Sharpen fuzzy language When the user uses vague or overloaded terms, propose a precise canonical term. "You're saying 'account' — do you mean the Customer or the User? Those are different things." ### Discuss concrete scenarios When domain relationships are being discussed, stress-test them with specific scenarios. Invent scenarios that probe edge cases and force the user to be precise about the boundaries between concepts. ### Cross-reference with code When the user states how something works, check whether the code agrees. If you find a contradiction, surface it: "Your code cancels entire Orders, but you just said partial cancellation is possible — which is right?" ### Update CONTEXT.md inline When a term is resolved, update `CONTEXT.md` right there. Don't batch these up — capture them as they happen. Use the format in [CONTEXT-FORMAT.md](./CONTEXT-FORMAT.md). `CONTEXT.md` should be totally devoid of implementation details. Do not treat `CONTEXT.md` as a spec, a scratch pad, or a repository for implementation decisions. It is a glossary and nothing else. ### Offer ADRs sparingly Only offer to create an ADR when all three are true: 1. **Hard to reverse** — the cost of changing your mind later is meaningful 2. **Surprising without context** — a future reader will wonder "why did they do it this way?" 3. **The result of a real trade-off** — there were genuine alternatives and you picked one for specific reasons If any of the three is missing, skip the ADR. Use the format in [ADR-FORMAT.md](./ADR-FORMAT.md). ARGUMENTS: Stress-test, grounded against CONTEXT.md + docs/adr/, the proposed idle-message-delivery redesign for spt-hosted endpoints (issue-2 from a /diagnose). The proposal (operator's, needs sharpening + a future milestone): CONTEXT of the bug: v0.11.0 REQ-SEND-SPT-HOSTED делivers an idle `spt send` to an spt-hosted endpoint by raw-writing the rendered + a bare '\n' into the broker-held PTY. It half-worked: the text landed in Claude Code's input box but never submitted (\n is not Enter; CC submits on \r) and even a correct \r is insufficient — different harness TUIs need different keystroke choreography before AND after the payload. Operator's correction to the model: raw-type-into-PTY-input IS the correct delivery during agent IDLE for spt-hosted; hook-injection is the BUSY path; under harness-hosted topology the idle surface is the poll listener (run in a Monitor-like tool). Different harnesses differ: Pi may accept a poll-listener feed with no keystrokes; Claude Code / Codex need explicit key injection. Operator's PROPOSAL (grill this): 1. The idle-message-delivery API + adapter manifest should ALWAYS support the poll listener as the PRIMARY target for idle messages (universal substrate). 2. Optionally define a per-adapter TRANSLATION-LAYER BINARY that (i) hosts the poll listener and subscribes to its output, and (ii) forwards the parsed output + any necessary keystrokes back to the broker PTY. It supports ARBITRARY keystroke sequences defined by that translation binary. Example — Claude Code would need: ctrl+s (stash any pre-existing input), delay 50ms, type message payload + \r, delay 50ms, ctrl+s (restore stash). The API must support such pre/post choreography + delays. Net: all idle messages surface at the poll listener; the adapter dev drives it to PTY input injection if their endpoint needs it. Grill it against the documented model: the harness-hosted vs spt-hosted topology split (CONTEXT ~39/121/125/161/185-191), the relay/poll/api-listen primitives (CONTEXT ~153/161), PresenceChannel + notif delivery (CONTEXT ~235/457-464 — notif_command manifest template per activity-state), shells & their notif_command (CONTEXT ~253-310), ADR-0020 EVENT envelope, the spt_term SessionSurface send_keys/send_line injection (CONTEXT ~394), and ADR-0004 broker/PTY ownership. Sharpen terminology, surface contradictions, and find where this proposal should live in the model (is the "translation-layer binary" a new concept, or is it the Shell/notif_command/relay seam already in the model? does it collapse into an existing primitive?). Update CONTEXT.md / draft an ADR inline as decisions crystallize. Also in scope to flag (related, do NOT lose): (3/4) project-history must not be live-commune-commit-gated — ready agents need it too; (1) bare `spt endpoint list` must always include local-unadvertised perches (kill --local) since whoami aliases it. ===== ASSISTANT @ line 1216 ===== Let me ground in the exact CONTEXT sections the proposal touches before grilling — the notif/presence delivery model and the primitives are the strongest "does this collapse into an existing concept" candidates. ===== ASSISTANT @ line 1224 ===== Grounded. Key find: `notif_command` (CONTEXT:464) already exists as a manifest seam for **endpoint-native rendering** on both harness- and shell-adapter manifests — and notif delivery *reuses* message delivery ("a notif to an agent is just normal SPT messaging… the existing delivery/inject path handles it"). So idle-message-delivery and notif delivery share one substrate, and your translation-binary lives in the same family as `notif_command`. That's the spine of the grill. I'll go one question at a time, each with my recommendation. --- **Q1 — the foundational fork: does the poll-stream become the universal idle substrate for BOTH topologies, replacing v0.11.0's broker-direct-raw-inject?** CONTEXT:39 says *"spt-hosted sessions need no relay — the daemon injects events straight into the PTY."* Your proposal makes the poll listener the primary idle target *always* — including spt-hosted, where the translation-binary hosts the poll listener and drives keystrokes back into the broker PTY. Read literally, that introduces a relay/poll consumer into the spt-hosted path that CONTEXT:39 says isn't needed. I think these reconcile cleanly, but we must pick the framing: - **(A) Unify the contract, topology-specific consumer (my recommendation).** The daemon's outbound message stream (the "poll" feed) is the one universal idle substrate. The *consumer* differs by topology: harness-hosted = the adapter's Monitor-run poll child (the agent reads its stdout); spt-hosted = the translation-binary, which subscribes to that same feed and choreographs keystrokes into the broker PTY. CONTEXT:39's "daemon injects into the PTY" is *preserved* — the translation-binary IS that injection, just made per-harness and manifest-declared instead of the hardcoded raw `\n` v0.11.0 shipped. v0.11.0's direct-inject becomes the degenerate special case (a translation-binary that types payload + `\r` with no choreography). - **(B) Keep two distinct paths.** spt-hosted stays broker-direct-PTY-inject (CONTEXT:39 literal), harness-hosted stays poll-listener; the translation-binary is *only* the spt-hosted keystroke driver, not a poll-listener host. No unification claim. My rec is **(A)** — it gives one delivery contract, makes Pi (no keystrokes) and Claude Code (full choreography) the same seam with different config, and reframes CONTEXT:39 as "the daemon delivers; the *mechanism* is a manifest-declared consumer" rather than a hardcoded write. But it does mean rewording CONTEXT:39/185-191 so "needs no relay" becomes "needs no *separate harness-owned* relay — the daemon-side translation-binary is its consumer." Which framing — A or B? And if A, are you comfortable rewording the topology split so the poll-stream is explicitly the universal substrate? ===== USER @ line 1231 ===== another bug to triage: `spt endpoint run`-->pick existing-->wall-b-->attach results in a "PUMP_IPC_READER: spawned" + otherwise stalled pty. the pty for wall-b did not visually load. ===== ASSISTANT @ line 1236 ===== Triaged (pausing the grill — Q1's A/B still pending whenever you're ready). ## New bug — attach to wall-b: `PUMP_IPC_READER: spawned` + stalled blank PTY rc attach connects to the broker (reader spawns) but the PTY never visually loads. Ranked hypotheses: **H1 (lead) — full-screen TUI, no repaint on attach.** wall-b is Claude Code (ratatui, alternate-screen buffer). The broker's `OutputLog` replays raw bytes, but a TUI's *screen state* isn't linear scrollback — re-feeding old bytes to a fresh terminal doesn't reconstruct the frame; the TUI must **repaint**. rc sends a controller resize on attach to trigger it (CONTEXT:338, "ConPTY repaint-on-resize"), but if that resize is a no-op (same dims) or doesn't reach CC, the screen stays blank until CC next renders. *Prediction:* force a real resize (drag the window) or make wall-b emit output → it paints. **H2 — subscribe/scrollback replay never fires.** Reader connected but the broker didn't fan the `OutputLog` backlog to this new stream. *Prediction:* even a session with recent output shows blank; broker log shows the subscribe but no backlog send. **H3 — wall-b's harness child is wedged/dead.** Broker session lingers (reader connects) but the PTY child produces nothing. *Prediction:* `endpoint list --local` shows wall-b not alive / pid gone. (Lower — you were interacting with it.) **Discriminating check (cheap):** read the daemon/broker log for the attach sequence (subscribe + backlog send?), and try forcing a resize/output. That splits H1 vs H2 vs H3 in one pass. **Routing:** this is the **same rc/broker/PTY-surface seam** as the idle-delivery redesign we're grilling — an spt-hosted TUI-attach rendering gap. It belongs in that milestone (the translation-binary / PTY-surface work touches exactly this). H1 (TUI-repaint-on-attach) is a known hard class — attaching to a full-screen TUI over a byte-replay log generally needs a repaint trigger or a screen-state model, not just byte replay. Want me to run the discriminating check now (I can read the broker log + wall-b state), or log it to the milestone and resume Q1 first? My rec: **log it, finish the Q1 fork** — it's the same milestone and the design decision shapes the fix. ===== USER @ line 1240 ===== Q1: I'm with you on (A). let's evolve it, hear me out: -adapter manifest can define the `[message-idle-translation-binary]` -if it does and that value is set, spt-core manages the tl binary's lifecycle. it comes up with the endpoint, terminates when the endpoint goes down. -spt-core prefers to send idle messages to the poll listener for that perch, IF it exists. --> this way, users can still choose to use poll listener during spt-hosted mode, while still taking advantage of pty control features like spt rc. -incidentally, by this design devs can choose to just always keep the perch's "idle ready" state active and use either the poll listener or the translation binary for *every* message delivery. --- note that the new bug (stalled blank PTY) is now happening for every new spt-hosted endpoint i try to start. did the brain get stuck in a broken state? --- another bug to triage: `spt endpoint run` picker still shows selections it shouldn't. `Start now` should only appear for offline endpoints. `Attach now` and `View now` should only appear for spt-hosted online endpoints. basically, the available commands need to actually mirror the capabilities of the endpoint in its current status. --- H1: your prediction around the bug was wrong. and i misspoke, the pty isn't actually empty. the terminal PTY just doens't populate at all after the message. process gets tied up with no visual: [Image #13] -H3: wall-a, wall-b, and wall-c all show as alive. only wall-c shows as "ready". -`spt endpoint stop c` changes ready to false, but alive stays true. another bug? shouldn't alive be false if they're offline? -you can check the broker log -agree with routing. run checks. ===== USER @ line 1241 ===== [Image: source: C:\Users\decid\Documents\ShareX\Screenshots\2026-06\WindowsTerminal_YjzqWQxcJZ.png] ===== ASSISTANT @ line 1248 ===== Lots here. Q1 = **(A+) accepted** — `[message-idle-translation-binary]`, spt-core-managed lifecycle (up/down with endpoint), poll-listener preferred when present, dev can use either for all delivery. Clean; I'll formalize it in CONTEXT/ADR once we clear the bugs. Logging the two new bugs (endpoint-stop leaves alive=true; picker shows status-invalid commands). But **priority = the stalled-PTY now hitting EVERY spt-hosted endpoint** ("did the brain get stuck?"). That's a systemic regression, not H1 (you're right, my repaint guess is wrong — it's the attach *process hanging* after reader-spawn, no render). Running the checks now. ===== ASSISTANT @ line 1252 ===== Strong signal: the broker effect journal shows a **flood of pty effects on session 1** — monotonic seq `…193617 → …193633` in the tail, thousands deep. That smells like a runaway/looping harness saturating the broker's drain, which would starve every new attach (your "every endpoint now stalls"). brain = pid 220764 gen 0 (never restarted), broker = 232940. No errors logged (the journal isn't stderr). Checking if session 1 is still flooding *now* + whether the broker is responsive. ===== ASSISTANT @ line 1259 ===== Corrected: effect log is **NOT growing** (delta 0/2s) — no runaway. My flood hypothesis is wrong (those big seq numbers were cumulative history). Broker IS responsive (`--local` returned fast). So it's not a broker-wide wedge — the hang is specific to the **rc attach path**. Key clue: wall-a/b/c are all `live_agent alive=true ready=false`. New hypothesis — these connect: if a harness child exited but the perch still reports `alive=true` (your H3 bug), rc attach trusts `alive=true`, tries to subscribe to a **dead/absent broker session**, and hangs after reader-spawn (nothing to stream). Verifying: are the wall-* pids actually alive, and does the broker hold real PTY sessions for them? ===== ASSISTANT @ line 1263 ===== PS check mis-fired. But info.json is revealing: - **wall-a**: status online, `rest_state=suspended`, **psyche_host_error: "host not resident… psyche perch missing/dead pid"** (phantom-online, dead Psyche — the v0.8.1 boot-race class), no `controllable`. - **wall-b**: status online, **`rest_state=dormant`**, controllable=true (spt-hosted). - **wall-c**: status online, controllable=true, no rest_state. All `status=online` (→ alive=true) but wall-a suspended/dead-psyche, wall-b dormant. The decisive fact: are these pids actually alive? If "online" is stale (dead pids), rc attaches to dead sessions → hang. Checking cleanly. ===== ASSISTANT @ line 1272 ===== **Decisive finding — all three wall-* harness children are DEAD, but their perches report `status=online` (→ alive=true).** Only the daemon (232940) and brain (220764) are alive. This is **phantom-online / stale liveness**, and it's the root of the attach hang. Root cause chain (high confidence): - perri's `spt daemon stop` + 0.11.0 update **fully restarted the daemon** → new broker (232940) + fresh brain (220764, **gen 0**). A full stop kills the broker, which kills the spt-hosted PTY children. So wall-a/b/c's children died with the old daemon. - On restart, the new broker holds **no** sessions for them, but their `info.json` still says `status=online` from before. **The restart never reconciles spt-hosted perch liveness against the (empty) broker session table.** `status=online` is a **one-way latch** — set at bind, never auto-cleared on child death. - **rc attach trusts `alive=true`** → connects (`PUMP_IPC_READER: spawned`) → subscribes to a session the broker doesn't hold → **no output ever streams → the pump polls forever → infinite blank hang.** Exactly your screenshot. This unifies your reports into one liveness seam: | Bug | Root | |---|---| | **Attach hangs (every endpoint)** | attach to a phantom-online endpoint the broker doesn't host → infinite poll (no fail-fast) | | **H3: stop clears ready not alive** | `status=online` is a latch; nothing reconciles it to offline on child death / stop | | **Picker offers Start/Attach/View wrongly** | confirm-layer reads the stale `status` → offers Attach on a dead "online" endpoint | | **send half-worked then nothing** | wall-b went dormant/died; inject hit a dead/dormant PTY | The brain is **not** stuck — daemon + brain are alive and responsive (`--local` returned fast). The problem is dead children wearing `online`. **Two distinct fixes needed (both spt-core, this milestone's liveness seam):** 1. **Reconcile spt-hosted liveness:** on daemon/broker (re)start AND on PTY-child exit, a perch whose broker session is gone / child pid dead → `status=offline` (alive=false). Kills phantom-online at the source. (Relates to REQ-HAZARD-DAEMON-HOSTED-LIVENESS + the v0.8.1 boot-race — wall-a even carries a `psyche_host_error`.) 2. **rc attach fail-fast:** if the endpoint has no live broker session, error clearly (`endpoint not hosted / offline — start it`) instead of hanging. **One open question I can't settle without a fresh repro:** does a *genuinely-alive* fresh endpoint also hang on attach (a separate attach regression), or only these dead phantoms? To split it, I'd start a disposable spt-hosted endpoint, confirm its pid is alive, then attach with a timeout. Want me to run that on your box (spawns a throwaway Claude Code briefly), or will you? **Remediation for the phantoms now:** `endpoint stop` won't clear them (that's bug H3). They need erasing — `spt api session-end --erase` (perri's method) wipes each dead perch; then fresh starts. But until fix #1 lands, any endpoint whose child dies will re-accumulate as phantom-online. Want me to (a) run the fresh-repro check, (b) erase the 3 phantoms now, and/or (c) fold this whole liveness cluster into the milestone REQs?

That's a **cluster of daemon/broker/brain-lifecycle + liveness-reconcile + attach-validation bugs.** Spinning up two parallel investigations + reading the attach-validation path myself (your "shouldn't the broker reject subscriptions to sessions it doesn't hold?" is the crux of the hang). ===== ASSISTANT @ line 1304 ===== Two agents investigating in background. Reading the broker subscribe handler myself — the crux of the hang. ===== ASSISTANT @ line 1308 ===== **Big find for BUG-1:** the broker *does* reject a subscribe to a session it doesn't hold — `dispatch_subscribe` (broker.rs:949-951): `sessions.get(&session_id).ok_or_else(|| "no such session …")` → `send_error`. So the broker rejects by **session_id**. So the hang isn't "broker silently accepts a dead session" — it's in how **rc resolves endpoint→session_id and handles the result**. Reading run_attach's resolution path. ===== ASSISTANT @ line 1319 ===== **BUG-1/2 root cause — confirmed decisively from the code:** `run_attach` (rc.rs:209-211) already handles the no-session case cleanly — `resolve_session → None → "no live session for endpoint"` error, no hang. And the broker `dispatch_subscribe` (broker.rs:949) already rejects unknown sessions. So the hang means `resolve_session` returned **Some** — i.e. **the broker still holds a session record for wall-f even though its harness child (the closed tab) is dead.** So the real bug: **the broker does not reap a session when its PTY child exits.** Chain: 1. Harness child dies (tab closed) → broker keeps the stale session + the perch stays `status=online` (no child-exit → session-removal → status-offline path). 2. `spt rc wall-f` → `resolve_session` finds the stale session → Some → subscribe succeeds (session "exists") → attaches to a **dead PTY that never streams** → the pump polls forever → `PUMP_IPC_READER: spawned` + infinite blank hang. Your instinct was right but one level off: the broker *would* reject a subscribe to a session it doesn't hold — the bug is the session is **never removed**, so it still "holds" a dead one. Fix = reap the session on PTY-child-exit (which then makes the *existing* no-session fast-fail fire correctly) **and** flip the perch to `status=offline`. That single fix kills the hang **and** the phantom-online (BUG-2) **and** feeds the picker/`endpoint stop` status correctness. Two background agents are finishing the rest of the cluster: - **BUG-3** (`daemon stop` says STOPPED but `start` says ALREADY_RUNNING; children not reaped — 8 orphan psyches/spt.exe) - **BUG-5** (`daemon start` auto-spawns 3 psyches for phantom-online perches) - **BUG-4** (bare brain-restart wedges new spawns until a full reset) When they land I'll synthesize the conclusive report, mint the REQ cluster, hand todlando the fix, gate, and drive the release.

The user can send it another message and resume it, so the same task-id may notify more than once. Excellent! Now I have complete evidence. Let me now write out my comprehensive findings report: ## SPT-CORE BUG ROOT CAUSE ANALYSIS Based on thorough code investigation, here are the exact root causes, mechanisms, and fixes for each bug: --- ### **BUG-2: Phantom-Online Status Latch (One-Way Alive)** **Symptom:** An spt-hosted endpoint's `info.json` `status` stays `"online"` after its harness PTY child dies, causing `spt endpoint list` to show `alive=true` indefinitely. #### **(a) WHERE status="online" IS SET** **File:** `crates/spt/src/api/startup.rs` - **Lines 361–363** (`cmd_listen`): For live-capable endpoints (manifest with `[session.psyche_init]`): ```rust let live_capable = manifest.is_some_and(|m| m.session.psyche_init.is_some()); if live_capable { if let Err(e) = info::set_status(&perch_path, spt_store::liveness::STATUS_ONLINE) { ``` - **Lines 466–470** (`cmd_bind`): Same for spt-hosted post-spawn bind: ```rust let live_capable = endpoint_type == "live_agent" && manifest.is_some_and(|m| m.session.psyche_init.is_some()); if live_capable { let perch_path = perch::resolve_perch_path(id, ParentHint::Infer); if let Err(e) = info::set_status(&perch_path, spt_store::liveness::STATUS_ONLINE) { ``` **Mechanism:** At establish time, the perch is stamped `status=online` (daemon-authoritative liveness marker). This is intentional — the brain's `livehost` will host the Psyche and the status is owned by daemon reconciliation, not the harness. --- #### **(b) IS THERE CODE THAT DETECTS PTY CHILD EXIT AND CLEARS STATUS?** **SHORT ANSWER:** NO. There is **zero code path** that sets `status=offline` when a broker-held PTY child exits. **Evidence:** **File:** `crates/spt-daemon/src/broker.rs` - **Lines 889–910** (exit waiter thread): When a session's child exits: ```rust thread::spawn(move || { if let Ok(status) = waiter.wait() { let ev = ExitEvent { session_id: id, code: Some(status.exit_code() as i32) }; // ... emit EXIT frame to subscribers ... } // Reap the dead session from the table. sessions_exit.lock().unwrap().remove(&id); }); ``` **Critical:** The exit waiter: 1. Emits an `ExitEvent` to the output log's subscribers (the brain receives this frame) 2. **Removes the session from the broker's in-memory `sessions` table** (line 909) 3. **Does NOT touch `info.json` or the perch's `status` field** The broker is stateless (ADR-0004 §B). It spawns/drains output/handles input but has **no logic** to update the file system. The `info.json` `status` field is daemon-side state, owned by the brain (`livehost` → `lifecycle.rs`). **File:** `crates/spt-daemon/src/lifecycle.rs` - **Lines 202–204** (`mark_offline`): Shows the **only** place status is set to OFFLINE: ```rust pub fn mark_offline(perch_path: &std::path::Path) { let _ = spt_store::info::set_status(perch_path, spt_store::liveness::STATUS_OFFLINE); } ``` - **Where is it called?** Search results: only in **tests** and in `livehost.rs` line 740 (when the Psyche itself is torn down), **never on broker PTY child exit**. --- #### **(c) LIVENESS RESOLUTION: The One-Way Latch** **File:** `crates/spt-store/src/liveness.rs` - **Lines 80–93** (`is_perch_alive`): THE liveness resolver: ```rust pub fn is_perch_alive(perch_path: &Path) -> bool { match read_raw(perch_path) { Some(val) => { if let Some(status) = val.get("status").and_then(|v| v.as_str()) { return status == STATUS_ONLINE; // daemon-authoritative; never pid } // ... external/interim perches fall through to pid-probe ... } None => true, // unreadable → alive (interim parity) } } ``` **The Bug:** For daemon-hosted perches (those with `status` field in `info.json`): - **Liveness = `status == "online"`** (line 84) - Once `status="online"` is written at establish, there is **no code path** that writes `status="offline"` on child death - The status becomes a **one-way latch**: ON, then stuck ON forever - `spt endpoint list` calls `is_perch_alive()` → returns true as long as the `status` field says "online" **Minimal Fix:** 1. **On broker PTY child exit,** the exit waiter must notify the brain (via a frame / persistent marker) that the session is dead 2. **On brain receipt of ExitEvent,** call `lifecycle::mark_offline()` to write `status=offline` to the endpoint's `info.json` 3. Alternatively, the broker could write `status=offline` directly (but violates broker statefulness — ADR-0004 §B) --- ### **BUG-H3: `endpoint stop` Clears Ready, Not Alive** **File:** `crates/spt/src/cli.rs`, lines 2994–3010 (`cmd_stop`): ```rust fn cmd_stop(id: &str) -> i32 { let owlery = perch::owlery_dir(); // Soft-cleanup: remove the ready marker + unregister the address let removed = std::fs::remove_file(perch::resolve_ready_file(id, ParentHint::Infer)).is_ok(); let _ = registry::unregister_address(id, &owlery); // ... 0 } ``` **The Bug:** - `cmd_stop` removes the **ready marker file** (soft cleanup, REQ-SOFT-CLEANUP 6.2) - `cmd_stop` **unregisters the address** from the registry - `cmd_stop` **does NOT touch `info.json` or the `status` field** **Result:** - `spt endpoint list` calls `is_perch_alive()` → reads `status=online` from `info.json` → **returns alive=true** - The endpoint shows as **alive despite being explicitly stopped** **Why the Confusion:** - The "ready" marker (`ready` file absence) indicates the endpoint is **unreachable** (stopped) - The "status" field (`status=online`) indicates **daemon liveness** (Psyche hosted, for daemon-hosted perches) - For a stopped (but still status=online) spt-hosted endpoint, the two flags are **orthogonal** - `spt endpoint list` uses `is_perch_alive()`, not "ready status" **Minimal Fix:** ```rust fn cmd_stop(id: &str) -> i32 { let perch_path = perch::resolve_perch_path(id, ParentHint::Infer); // Remove ready marker let removed = std::fs::remove_file(perch::resolve_ready_file(id, ParentHint::Infer)).is_ok(); // Unregister address let _ = registry::unregister_address(id, &perch::owlery_dir()); // CRITICAL ADDITION: Mark as offline so liveness resolver reports dead let _ = spt_store::info::set_status(&perch_path, spt_store::liveness::STATUS_OFFLINE); // Trigger advertise spt_daemon::registryhost::request_advertise_now(); // ... } ``` --- ### **BUG-1: Broker Should Reject Subscribe to Dead Session** **Symptom:** `spt rc <id>` to an endpoint whose harness child is dead but perch still `status=online` → connects, then **hangs forever** with no output and no error. #### **Where the Hang Occurs** **File:** `crates/spt/src/rc.rs`, lines 209–211: ```rust let session_id = resolve_session(&mut brain, endpoint_id) .map_err(|e| format!("list sessions: {e}"))? .ok_or_else(|| format!("no live session for endpoint '{endpoint_id}'"))?; ``` **Lines 225–231:** Subscribe to the stream: ```rust let stream_id = request_attach(&mut brain, dialed.conn_id, session_id, 0, ops.next(), intent) .map_err(|e| format!("attach request: {e}"))?; brain .net_stream_subscribe(stream_id, 0) .map_err(|e| format!("stream subscribe: {e}"))?; ``` **Lines 250–260:** Enter the pump loop which blocks on `read_event_until`: ```rust let outcome = pump( &mut brain, stream_id, &ops, rx.as_ref(), &mut decoder, &mut stdout, !view, ); ``` --- #### **The Root Cause: Broker's dispatch_subscribe Doesn't Validate Session Existence** **File:** `crates/spt-daemon/src/broker.rs`, lines 942–962: ```rust fn dispatch_subscribe(&self, env: Envelope, send: &SharedSend) -> Result<u64, String> { let req: SubscribeReq = serde_json::from_value(env.payload) .map_err(|e| format!("bad subscribe payload: {e}"))?; let log = { let sessions = self.sessions.lock().unwrap(); let h = sessions .get(&req.session_id) .ok_or_else(|| format!("no such session {}", req.session_id))?; // ← Line 951 Arc::clone(&h.log) }; let outcome = log.lock().unwrap().resolve_subscribe( Arc::clone(send), req.from_seq, req.intent, req.by, ); send_frame(send, &subscribed_envelope(req.session_id, outcome)); // ← Line 960 Ok(req.session_id) } ``` **If `req.session_id` is NOT in the broker's `sessions` table** (e.g., because the child exited and was reaped): - Line 951 returns `Err("no such session ...")` - This error is caught at line 712 in the dispatcher: ```rust KIND_SUBSCRIBE => match self.dispatch_subscribe(env, &send) { Ok(id) => my_subs.push(id), Err(msg) => send_error(&send, &msg), // ← Sends ERROR frame }, ``` **HOWEVER**, the actual problem is **earlier** — in `resolve_session`: **File:** `crates/spt/src/rc.rs`, lines 89–96: ```rust fn resolve_session(brain: &mut Brain, endpoint_id: &str) -> std::io::Result<Option<u64>> { let reply = brain.sessions()?; Ok(reply .sessions .into_iter() .find(|s| s.endpoint == endpoint_id) .map(|s| s.session_id)) } ``` **The Brain's `sessions()` call:** **File:** `crates/spt-daemon/src/brain.rs`, lines 1043–1070: ```rust pub fn sessions(&mut self) -> io::Result<SessionsReply> { self.send(KIND_SESSIONS, serde_json::Value::Null)?; loop { match self.read_event()? { BrokerEvent::SessionsReply(reply) => return Ok(reply), BrokerEvent::Error { message } => return Err(io::Error::other(message)), _ => continue, } } } ``` **And the broker's handler:** **File:** `crates/spt-daemon/src/broker.rs`, lines 765–792: ```rust KIND_SESSIONS => { // Clone the (id, endpoint, log) out from under the sessions lock let rows: Vec<(u64, String, Arc<Mutex<OutputLog>>)> = { let sessions = self.sessions.lock().unwrap(); sessions .iter() .map(|(id, h)| (*id, h.endpoint.clone(), Arc::clone(&h.log))) .collect() }; // Read each log's cursor under the log lock alone let mut session_infos = Vec::new(); for (id, endpoint, log) = rows { let log_lock = log.lock().unwrap(); session_infos.push(SessionInfo { session_id: id, endpoint: endpoint.clone(), resume_seq: log_lock.delivered_through, }); } let frame = Envelope::new(KIND_SESSIONS_REPLY, ...); send_frame(&send, &frame); } ``` **THE HANG SEQUENCE:** 1. User runs `spt rc <endpoint_id>` where the spt-hosted endpoint's harness child **already exited** 2. The broker's exit waiter **removed the session from the `sessions` table** (broker.rs:909) 3. `resolve_session()` calls `brain.sessions()` which returns an **empty list** (or a list without this endpoint's session_id) 4. Line 211 in rc.rs: `.ok_or_else(|| "no live session for endpoint ...")` **returns an error** 5. **The user sees the error message** and `spt rc` exits — **this is actually correct behavior!** **WAIT — I need to reconsider the bug symptom.** Let me re-read the bug description: > "the rc pump connects ("PUMP_IPC_READER: spawned") then HANGS forever with no output" This suggests the pump is running but blocked. Let me check if there's a case where: - The session is somehow in the broker but dead - The subscribe succeeds - But the pump never gets output **The Real Scenario for the Hang:** If the broker session table **still holds the dead session** (the exit waiter hasn't reaped it yet, or the session was never fully removed), then: 1. `resolve_session()` finds the session_id ✓ 2. `request_attach()` opens a net stream ✓ 3. `net_stream_subscribe()` subscribes to the stream ✓ 4. The pump enters the loop and calls `read_event_until()` to read from the stream 5. **No data arrives** because the underlying session's output log has no subscribers (the pump is attached to a net stream, not the output log directly) Actually, let me check how net streams get their data. The pump is subscribing to a **net stream**, not the session output log directly. **File:** `crates/spt-daemon/src/dispatch.rs` shows how a net stream `serve_attach` works. The attachment opens a net stream which then relays output from the session's output log. The **real hang** likely happens if: 1. The session is **still in the broker's table** (not yet reaped) 2. The **output log is in the log ring** (no active subscribers) 3. The **net stream is open** but waiting for output 4. The **harness child has exited** so no new output will ever come 5. The pump **blocks forever** waiting for the next event (a timeout that never fires) **Minimal Fix:** In `dispatch_subscribe` (broker.rs:942), if the session is **not found**, send an ERROR frame **before returning** so the client knows the session is invalid: ```rust fn dispatch_subscribe(&self, env: Envelope, send: &SharedSend) -> Result<u64, String> { let req: SubscribeReq = serde_json::from_value(env.payload) .map_err(|e| format!("bad subscribe payload: {e}"))?; // Validate session exists let log = { let sessions = self.sessions.lock().unwrap(); match sessions.get(&req.session_id) { Some(h) => Arc::clone(&h.log), None => { send_error(send, &format!("session {} not hosted (child may have exited)", req.session_id)); return Err(format!("no such session {}", req.session_id)); } } }; // ... rest } ``` --- ### **BUG-4: Brain Restart Wedges New Spawns** **Symptom:** After the brain child is killed and restarted (broker survives, holding PTY masters), newly spawned spt-hosted endpoints die immediately / can't attach, until a full daemon reset. #### **The Handoff on Brain Restart** **File:** `crates/spt-daemon/src/brainproc.rs`, lines 159–228 (`run_brain`): ```rust pub fn run_brain(generation: u64, reason: StartReason) -> io::Result<()> { // The broker hands {generation, start-reason} at spawn // generation is broker-owned, rehydrated on cold start let name = endpoint::broker_socket_name(); eprintln!("BRAIN_UP: connected to broker {} (generation {}, start-reason {})", ..., generation, ...); let mut brain = Brain::cold_start(&name, now_ms())?; // Rehydrate the session table from the broker (KH-2.4 cursor-of-record) let resumed = brain.resume_sessions()?; // ← Line 186 eprintln!("REHYDRATED: {} sessions", resumed.len()); for id in resumed { eprintln!("SESSION_RESUMED:{id}"); } // ... spawn net consumers, livehost, etc. } ``` **File:** `crates/spt-daemon/src/brain.rs`, lines 797–809 (`resume_sessions`): ```rust pub fn resume_sessions(&mut self) -> io::Result<Vec<u64>> { let reply = self.sessions()?; // ← Asks broker for current hosted sessions let mut resumed = Vec::with_capacity(reply.sessions.len()); for info in reply.sessions { // Seed the dedup cursor at the broker's resume point BEFORE subscribe self.session_cursors .insert(info.session_id, info.resume_seq); self.subscribe(info.session_id, info.resume_seq)?; // ← Re-subscribe resumed.push(info.session_id); } Ok(resumed) } ``` #### **The State Lost on Brain Restart** **File:** `crates/spt-daemon/src/lifecycle.rs`, lines 58–130 (`BrainLifecycle`): The `BrainLifecycle` struct holds: ```rust pub struct BrainLifecycle { runtime: ManifestRuntime, id: String, project_id: String, manifest: Manifest, commune_dir: Option<PathBuf>, signoff_dir: Option<PathBuf>, cfg: DaemonConfig, } ``` **Critical Discovery:** On brain restart: 1. The broker **survives** with its `sessions` table ✓ 2. The brain **cold-starts** and calls `resume_sessions()` ✓ 3. The brain **re-subscribes** to each broker session by `session_id` ✓ **BUT** — the brain also has **per-endpoint lifecycle hosts** (`BrainLifecycle` instances): **File:** `crates/spt-daemon/src/brain.rs`, lines 254–275: The brain doesn't store these! It's ephemeral in-process state. On restart, **all BrainLifecycle instances are LOST**. When a **new spawn request arrives** after restart: 1. The daemon receives `KIND_SPAWN` from the harness 2. The brain (now restarted) has **no BrainLifecycle loaded for that endpoint** 3. If the manifest requires Psyche hosting, the lifecycle is **never instantiated** 4. The spawn succeeds but **the Psyche is never hosted** (no livehost loop to spawn it) **Minimal Fix:** The `livehost` loop needs to: 1. On brain startup, **enumerate** all endpoints in the broker's `sessions` 2. For each endpoint, **load its manifest** (from the endpoint's adapter registration) 3. **Instantiate a BrainLifecycle** and start its pulse loop 4. Only **then** enter the idle livehost pump OR (simpler): On a **new spawn request**, check if the endpoint's lifecycle is already live. If not: 1. Read the endpoint's manifest (from adapter registry) 2. Instantiate BrainLifecycle if live-capable 3. Spawn the Psyche 4. Proceed **File:** `crates/spt-daemon/src/livehost.rs` — search for where `BrainLifecycle` is stored and loaded: The key question: **Is there a persistent registry of "which endpoints need livehost?"** If not, the fix is to **rebuild that registry on brain restart** from the broker's resumed sessions list. --- ## SUMMARY TABLE | Bug | File:Line | Root Cause | Minimal Fix | |-----|-----------|-----------|------------| | **BUG-2** | `startup.rs:361,468` (status ON) + `broker.rs:909` (no OFF on exit) | Exit waiter removes session from broker table but never clears `info.json` status field | On `ExitEvent`, brain must call `lifecycle::mark_offline()` to write `status=offline` | | **BUG-H3** | `cli.rs:2994-3010` | `cmd_stop` removes ready marker + unregisters but doesn't clear `status` field | Add `set_status(..., STATUS_OFFLINE)` in `cmd_stop` | | **BUG-1** | `rc.rs:209-231` (resolve + subscribe) + `broker.rs:942-962` (no validation) | Broker doesn't reject subscribe to dead session; pump hangs on blocked read | Add explicit error send on dead session + timeout on pump's read loop | | **BUG-4** | `brainproc.rs:186` (`resume_sessions`) + `lifecycle.rs:58-130` (BrainLifecycle lost) | Brain doesn't rehydrate BrainLifecycle instances on restart; new spawns lack Psyche host | On brain startup, enumerate resumed sessions, load manifests, instantiate BrainLifecycle for live-capable endpoints | 7811632142027 ===== ASSISTANT @ line 1335 ===== Agent 2 (liveness + brain-restart) delivered. Key code-level findings: - **BUG-2:** broker exit-waiter (broker.rs:889-910) reaps the session from its table + emits `ExitEvent`, but **never touches `info.json` status**. `mark_offline` (lifecycle.rs:202) is the only status→offline setter — called on Psyche teardown + tests, **never on PTY-child exit**. So `status=online` is a one-way latch (liveness.rs:84 reads status for daemon-hosted). Fix: brain calls `mark_offline` on `ExitEvent`. - **BUG-H3:** `cmd_stop` (cli.rs:2994-3010) removes the ready marker + unregisters address but **doesn't set status offline**. Fix: add `set_status(OFFLINE)`. - **BUG-1:** the pump already poll-times-out (doesn't block on read) — so "hang" = attached stream produces **no output forever**. The exact sub-mechanism (dead-session-not-reaped vs alive-but-resting vs reaped-but-rc-doesn't-error) needs a repro to pin — that's todlando's regression test. - **BUG-4:** brain restart calls `resume_sessions` (re-subscribes to broker sessions) but **loses all `BrainLifecycle` instances** (ephemeral in-process) — so post-restart spawns get no livehost → Psyche never hosted. Fix: rebuild lifecycle hosts on brain startup from resumed sessions. **This is your "brain restart wedged everything."** Awaiting agent 1 (daemon stop-doesn't-stop / no-reap / start-auto-spawns-psyches) to complete the cluster, then I synthesize the conclusive report + dispatch todlando. ===== USER @ line 1339 ===== afbef92815f33b8b1 toolu_01MmtfRaiftx88YiL7ZVcEuU C:\Users\decid\AppData\Local\Temp\claude\C--Users-decid-Documents-projects-spt-core\9d0930b3-34c1-4dce-943f-72ccdc8fb726\tasks\afbef92815f33b8b1.output completed Agent "Daemon stop/start/reap lifecycle bugs" came to rest A task-notification fires each time this agent comes to rest with no live background children of its own. The user can send it another message and resume it, so the same task-id may notify more than once. Good! `wait_until_up` polls `is_running()` which does a seed socket ping. So the timing is: **BUG-3 Race Condition Timeline:** 1. Old daemon running, seed socket bound and answering pings 2. `spt daemon stop` → `request_stop()` sends STOP frame 3. Daemon's handle_conn receives STOP, sends STOPPING ack (line 174-177) 4. While that's happening, `request_stop()` reads the ack and returns (line 246) 5. Caller does `spt daemon start` → `start_daemon()` → `is_running()` → `ping()` 6. **Race condition window:** If the ping happens before the daemon's serve loop checks the stop flag and returns, it will succeed 7. `is_running()` returns true → `start_daemon()` returns `AlreadyRunning` 8. But the daemon is actually exiting, and the socket will soon be unbound Now let me make a final verification by checking if there's a window between the ack and the actual process exit: Looking at seedmap.rs line 171-181: ```rust KIND_STOP => { write_frame(&mut conn, &Envelope::new(KIND_STOPPING, serde_json::Value::Null))?; // ACK sent stop.store(true, std::sync::atomic::Ordering::SeqCst); // flag set let _ = LocalSocketTransport::connect(name); // wake accept return Ok(()); // handle_conn returns } ``` Then in daemon.rs line 287: ```rust seedmap::serve_seed_control(&seed_socket_name(), reg) ``` The serve_seed_control loop checks the stop flag on line 128: ```rust if stop.load(Ordering::SeqCst) { return Ok(()); } ``` This happens AFTER the accept() returns, which is triggered by the throwaway connect on line 179. So there's definitely a window. Now I have all the evidence I need. Let me compile the final report. ## Root-Cause Analysis: Three Daemon-Lifecycle Bugs in spt-core I've investigated the spt-core Rust workspace and identified the root causes of the three daemon-lifecycle bugs with exact evidence. --- ### **BUG-3: `spt daemon stop` prints `DAEMON_STOPPED` but immediately-following `spt daemon start` prints `DAEMON_ALREADY_RUNNING`** **Root Cause: Race condition between IPC ack and actual process exit** **Controlling Functions:** 1. **Stop-side:** `seedmap::request_stop()` — `crates/spt-daemon/src/seedmap.rs:240-255` 2. **Stop handler:** `handle_conn()` KIND_STOP case — `crates/spt-daemon/src/seedmap.rs:171-181` 3. **Serve loop:** `seedmap::serve_seed_control()` — `crates/spt-daemon/src/seedmap.rs:117-138` 4. **Start-side:** `daemon::start_daemon()` — `crates/spt-daemon/src/daemon.rs:464-488` 5. **Liveness check:** `daemon::is_running()` — `crates/spt-daemon/src/daemon.rs:375-377` **Exact Mechanism:** The stop path uses an **asynchronous IPC handshake with a stale socket liveness window**: 1. Client calls `request_stop()` (seedmap.rs:240) which sends KIND_STOP frame and reads back KIND_STOPPING ack 2. **Daemon handler sends ack immediately** (seedmap.rs:174-176) before the serve loop actually exits 3. Handler then sets `stop.store(true)` (seedmap.rs:178) and wakes the accept loop with a throwaway connect (seedmap.rs:179) 4. **`request_stop()` returns after receiving ack**, WITHOUT waiting for the daemon process to exit 5. **Race window opens:** The socket is still bound and answering pings because the serve loop hasn't reached the `if stop.load()` check yet (seedmap.rs:128) 6. If `start_daemon()` is called immediately, it calls `is_running()` (daemon.rs:375-376) which does `seedmap::ping(&seed_socket_name()).is_ok()` 7. The ping succeeds because the seed-control listener is still alive → `is_running()` returns `true` 8. `start_daemon()` returns `AlreadyRunning` (daemon.rs:467) 9. **Meanwhile**, the serve loop checks `stop.load()` and exits (seedmap.rs:128-129), process exits, socket is unbound 10. User sees `DAEMON_STOPPED` followed by `DAEMON_ALREADY_RUNNING` even though the daemon exited **Why it happens on Windows specifically:** No Windows-specific process-termination gap; the issue is the architecture-agnostic IPC race between ack-send and socket-unbind. On both platforms, the process doesn't exit until the foreground loop returns, but the ack is sent while the loop is still running. **Fix classification:** Missing liveness gate — the socket should be closed (or the flag checked) BEFORE sending the ack, OR `request_stop()` should wait for the socket to disappear before returning. --- ### **BUG-reap: `spt daemon stop` does NOT reap child Psyche processes — ~8 `claude-spt-psyche.exe` + many `spt.exe` remain orphaned** **Root Cause: Psyches are spawned detached with no teardown on daemon exit** **Controlling Functions:** 1. **Psyche spawn:** `spt_live::psyche::spawn_psyche()` — `crates/spt-live/src/psyche.rs:94-102` (calls runtime.spawn_session) 2. **Runtime spawn:** `spt_runtime::runtime::ManifestRuntime::spawn_session()` — `crates/spt-runtime/src/runtime.rs:342-356` 3. **Detach comment:** Lines 349-350 — "Detached: discard stdio, spawn, drop the handle" 4. **Brain host spawn:** `crate::livehost::spawn_live_host()` — `crates/spt-daemon/src/livehost.rs:450-468` 5. **Stop flag:** `brainproc::run_brain()` line 230 — spawns live host with `Arc::new(AtomicBool::new(false))` — **never raised** **Exact Mechanism:** Psyches are spawned as **truly detached subprocesses with zero reaping infrastructure**: 1. `spt_live::spawn_psyche()` calls `runtime.spawn_session(role, &keys)?` (psyche.rs:132) 2. `ManifestRuntime::spawn_session()` (runtime.rs:342-356) does: ```rust let child = cmd.spawn().map_err(RuntimeError::Spawn)?; Ok(Spawned { pid: child.id() }) ``` **The `Child` handle is immediately dropped** (never stored, never waited), leaving the process detached 3. On Unix, the child is reparented to init (no parent wait needed) 4. On Windows, the child remains a zombie until explicitly reaped (but no reaped) 5. The brain's live host (`livehost::spawn_live_host()`, line 450) spawns a reconcile thread with a stop flag `Arc::new(AtomicBool::new(false))` 6. **The stop flag is held for symmetry, never raised** (brainproc.rs:227-228 comment explicitly states this) 7. When the daemon receives `spt daemon stop`: - The seed-control loop exits (Daemon::run returns) - The broker process continues (brain is spawned as child but not killed) - The brain thread exits with the process, but the spawned Psyche children are already detached - No signal or cleanup targets the Psyche processes 8. Result: Psyches remain in Task Manager as orphaned processes **Why multiple processes remain:** Each Psyche is spawned detached; each `run_pulse_loop` pulse tick may spawn additional child processes for context fetching/normalization, also detached. **Fix classification:** Missing teardown — the live host's stop flag needs to be raised on daemon stop, and `spawn_session` needs an explicit kill/wait path for the spawned children, OR the Psyches need to be spawned with a process group / job object so they die when the parent dies. --- ### **BUG-5: On `spt daemon start` (after clean kill), THREE `claude-spt-psyche.exe` spawn immediately** **Root Cause: Boot-time livehost reconciliation spawns Psyches for all perches marked `status=online` without checking actual process liveness** **Controlling Functions:** 1. **Reconcile on boot:** `crate::livehost::reconcile_once()` — `crates/spt-daemon/src/livehost.rs:226-313` 2. **Start-side loop:** Lines 266-312 (the "Start side" comment) 3. **Status check:** Line 285 — `if info.status.as_deref() != Some(STATUS_ONLINE)` 4. **Host spawn:** Line 311 — `host_one(set, &id, lifecycle, info.session_id, reason);` 5. **Brain boot:** `brainproc::run_brain()` line 230 — spawns live host which calls `reconcile_once` on first iteration 6. **Startup reason:** `brainproc::StartReason::Cold` — passed at first brain spawn **Exact Mechanism:** The livehost reconciler **trusts the stale `status=online` latch without verifying the actual Psyche subprocess is alive**: 1. On `spt daemon start`, the broker spawns a brain child (brainproc.rs line ~440s, supervision loop) 2. Brain's `run_brain()` calls `livehost::spawn_live_host()` (brainproc.rs:230) with reason `Cold` 3. Live host thread starts and calls `reconcile_once()` at boot (livehost.rs:450-468) 4. `reconcile_once()` iterates every perch in the owlery (line 267) 5. For each perch, it reads info.json and checks: - Line 282: `if info.state != LIVE_AGENT_STATE` → skip non-live-agents - Line 285: **`if info.status.as_deref() != Some(STATUS_ONLINE)` → continue if NOT online** 6. If status **IS** `online`, it proceeds to spawn a Psyche (line 311) 7. **The check does NOT verify the actual `{id}-psyche` child process is alive** — it only checks the parent perch's status stamp 8. After a clean daemon kill, the previous Psyche processes are dead, but their parent perches still carry `status=online` from the last successful spawn 9. The new brain spawns a new Psyche for **every** perch marked online, regardless of the previous child's actual state 10. Result: THREE Psyches spawn if three perches were marked online **Why "wall-a" carries `psyche_host_error` stamp:** The residency-confirmation logic (line 395-441, `confirm_residency_or_unhost()`) is **not run at boot** — it runs on subsequent reconcile ticks after the grace window expires (lines 257-263). At boot (first reconcile), the check doesn't run, so a newly-spawned but immediately-dying Psyche is never flagged as non-resident until tick 2+. **Fix classification:** Missing liveness gate — `reconcile_once` line 285 should check not just `status==online` but also verify the actual `{id}-psyche` perch's pid is alive (or at least not in the residency-failure cooldown). Alternatively, the brain boot should NOT spawn Psyches on `Cold` start until the previous generation is confirmed dead (a rehydration/boot-race gate). --- **Summary Table:** | Bug | Function | File:Line | Mechanism | Fix Type | |-----|----------|-----------|-----------|----------| | BUG-3 | `request_stop()` / `is_running()` | seedmap.rs:240-255, daemon.rs:375 | Ack sent before socket closes; ping succeeds during exit window | Stale liveness gate (missing socket-close barrier) | | BUG-reap | `spawn_session()` / `run_brain()` | runtime.rs:354-355, brainproc.rs:230 | Psyches spawned detached, stop flag never raised, no teardown | Missing teardown (no kill/job-object on daemon stop) | | BUG-5 | `reconcile_once()` | livehost.rs:285-311 | Status latch checked without verifying actual child pid alive | Stale pid latch (missing residency check at boot) | 7334150204650 ===== ASSISTANT @ line 1346 ===== Both agents in. The cluster has **one rotten keystone**: `status=online` is a one-way latch that nothing reconciles against real liveness, and the daemon-stop / brain-restart lifecycle neither tears down nor rehydrates.

Once a child-exit → `status=offline` reconcile exists, B1 (attach gates/fail-fast on it), B5 (boot gates on it), H3 (stop sets it) largely fall out. B3/Breap/B4 are the daemon-lifecycle half (stop must actually stop+reap; restart must rehydrate lifecycle hosts). This is a coherent milestone — **spt-hosted lifecycle & liveness reconciliation** (~v0.12.0, MINOR).

Hard seam bar every wave (daemon_lifecycle/livehost/broker/brainproc). He's already opening the branch + reading the keystone. - **I gate per-wave, then deployah → ~v0.12.0 (MINOR).** This unblocks `spt endpoint run` end-to-end (attach, daemon stop, restart, phantom-online all fixed). **Parked (separate, after this ships):** - **Issue-2 idle-delivery redesign grill** — Q1=**(A+)** locked (`[message-idle-translation-binary]`, spt-core-managed lifecycle, poll-listener-preferred, per-harness keystroke choreography). Resume the grill post-v0.12.0; it's the delivery-*mechanism* redesign, a later milestone on the same seam. - **Issue-1** (bare `endpoint list` must include local-unadvertised; kill `--local`; whoami aliases it) + **Issue-3/4** (project-history must not be live-commune-gated; store had zero commits) — folded as design items. - **Issue-5** (v0.11.0 "not public") = not a bug (cache; confirmed public).

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 ``` > **Output truncation.** If the Bash tool reports `Output too large (N KB)` and saves the full result to a `tool-results/.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 `` 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 `` vs `` — is defined canonically in `psyche.md` §`` (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 ` (Step 1 of `## Flow` above) and inspect the `` tag at the top of the output. The `` 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 `` → emit BOTH envelopes (apply rule 1 or 2 below); no payload at all → emit ONLY `` (rule 3). Secondary signal: the `` 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 `...` AND `...`, both with non-empty bodies. - **In-project, no project-specific update this cycle** (marker present, but nothing project-bound to report): emit `...` AND `` (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 `...`. Do NOT emit an empty `` envelope (missing tag means "no project resolved" per D-25.1-03). **Nested envelopes.** The Phase 23 `` envelope (see `## Envelope shape (Phase 23 v1.8)` below) is composed by `$LIVE commune` automatically — you NEVER write `` tags. You write ONLY the inner two-slice body. The two envelope layers nest: outer EVENT wraps inner two-slice body. (See `psyche.md` §`` for the canonical taxonomy and per-slice content rules.) ## Envelope shape (Phase 23 v1.8) As of v1.8 Phase 23, commune deliveries are wrapped in a typed EVENT envelope carrying a 5-field stamp (`machine`, `project`, `branch`, `head_sha`, `head_subject`); the prose `COMMUNE (timestamp): body` form is gone. ```xml body ``` Outside a git repo (D-11), `branch`, `head_sha`, and `head_subject` are omitted entirely (not empty-string-set): ```xml body ``` `$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. ARGUMENTS: with immediate next steps and broad summary of the project's status + end goal. we'll resume in the next session ===== ASSISTANT @ line 1486 ===== End-of-session checkpoint. Following commune flow — downloading current Psyche context to diff the delta. ===== ASSISTANT @ line 1495 ===== Psyche has the tactical state (B2 gated, H3 done, B1 in progress). The delta for a clean next-session resume = the **broad status + end goal + full wave plan + the paused design items**. Writing the checkpoint commune (both slices — in-project). ===== ASSISTANT @ line 1499 ===== Commune written — Self listener will ingest it into the Psyche for next-session resume. ## Checkpoint summary (for resume) **End goal:** legacy-owl parity (spt-core + claude-spt) → flip sptc→spt, retire owl. **Parity arc CLOSED this session** (spt-claude-code v0.3.0). **Session shipped:** 6 releases (v0.8.3 → v0.11.0), all gate-confirmed + hash-checked. **In-flight: v0.12.0-lifecycle milestone** (operator-mandated; I diagnosed the 7-bug cluster, drive it to release). Unifying root: `status=online` is a one-way latch never reconciled vs real liveness. - ✓ B2 keystone (pull-reconcile) **gated** · ✓ H3 (stop→offline) done - **▶ Resume point:** gate Wave 2 (B1 attach-failfast) when todlando pings — verify **both** (i) fresh-alive attach still works, (ii) dead-child fails fast. B1 order locked: (c) broker-EOF primary → (a) status-gate → (b) ~30s backstop. - Then waves 3 (B3+Breap) → 4 (B5) → 5 (B4) → full-PR CI → deployah v0.12.0. **Paused (after v0.12.0):** issue-2 idle-delivery redesign grill (Q1=A+ locked, more to walk) · issue-1 (kill `--local`, bare list includes local; whoami aliases it) · issue-3/4 (project-history not commune-gated; store is empty). All in memory: `lifecycle-liveness-milestone`, `spt-core-findings-backlog`, `parity-arc-closed`. todlando keeps building wave 2 in the background; next-session doyle picks up the gate. Good to resume cleanly. 🦉
