/grill-with-docs new features: 1. for the translation binary output, color the entire `<EVENT ...>...</EVENT>` block's text cyan, including the tags themselves. to help the user visually distinguish i…


Now I have the full picture. Both features collide with hard constraints — let me grill from the root of the dependency tree.

**Findings so far (grounding):**

**Feature 1 (cyan EVENT block):** The translation binary's entire output vocabulary is `{key}` · `{delay_ms}` · `{text}` · `{commit}` (main.rs:80-93). The envelope rides in `{text}`, which spt-core applies **verbatim into CC's TUI input box** — then a discrete Enter submits it as a user turn. There is no color primitive. And your own F-019 probe table already recorded that escape sequences in `{text}` get **eaten as input**, not rendered (`SPT-CORE-FINDINGS.md:1071`: `{text:"\x1b[13u"}` → no-op). So ANSI bytes wrapped around the envelope wouldn't paint it cyan — they'd corrupt the injected text. CC renders user turns in its own style; it does not honor caller ANSI. So "color cyan" as described isn't reachable through the delivery path the binary owns.

That makes the first question a *where does the color even live* question, before any design.


AskUserQuestion

Question: Feature 1: the binary injects the envelope as text INTO Claude Code's input box (CC then renders it as a user turn). There's no color command in the inject vocab, and ANSI bytes in {text} get eaten as input (your own F-019 probe proved this). So where do you actually want the cyan to appear?

Choices:
Conclude cyan is NOT adapter-buildable on the public surface: it needs a new inject capability (a color-tagged text command spt-core renders to the PTY, or CC-side envelope recognition). Log it for doyle, build nothing adapter-side. Matches the public-surface-only thesis.
binary --{text}--> CC input box --submit--> user turn
                       ^ CC owns rendering, plain style
ANSI in {text} = eaten as keystrokes (F-019:1071)
=> no adapter-side path; FINDING for spt-core
Don't touch CC's rendering. Colorize the envelope only where SPT itself prints it (e.g. `spt rc --view`, broker echo, logs). The user watching via spt sees cyan; the in-CC user turn stays plain. May still need an spt-core hook.
CC terminal: plain user turn (unchanged)
spt rc --view: <EVENT...>  <- cyan here
   (spt controls this surface, not CC)
Before deciding, probe whether Claude Code renders ANY caller-controlled color in submitted user text (it almost certainly does not). Spend a probe cycle to confirm/deny before calling it a finding.
probe: can CC color a user turn at all?
 -> if no (expected): same as 'finding'
 -> if yes: design around that hook

spt rc --view: <EVENT...>  <- cyan here
   (spt controls this surface, not CC)
Before deciding, probe whether Claude Code renders ANY caller-controlled color in submitted user text (it almost certainly does not). Spend a probe cycle to confirm/deny before calling it a finding.
probe: can CC color a user turn at all?
 -> if no (expected): same as 'finding'
 -> if yes: design around that hook


Good — investigate before concluding. Let me probe CC's actual rendering behavior two ways in parallel: an authoritative CC-capabilities consult, plus an empirical injection test on a live endpoint.

CC user-turn color rendering

Prompt:
I need a precise answer about Claude Code's TUI rendering, for a terminal-automation feature.

Question: When text is programmatically typed into Claude Code's prompt/input box (as if keystrokes) and then submitted as a user turn, can the CALLER control the COLOR of that text as it renders in the terminal?

Specifically:
1. Does Claude Code's input box interpret ANSI/SGR escape sequences (e.g. ESC[36m for cyan) embedded in typed text — i.e. would they colorize the text, or are they stripped/eaten/treated as literal characters?
2. When a user message is rendered in the transcript scrollback, does CC apply any caller-controllable styling, or is the user-turn style fixed by CC's own theme?
3. Is there ANY supported mechanism (markdown, a control sequence, a setting) by which an external automation could make a specific user-submitted message render in a distinct color (e.g. cyan) to visually flag it?

I need a definitive yes/no on each with reasoning. Background: recent CC versions negotiate win32-input-mode / CSI-u (kitty) keyboard protocol; injected control bytes in the input box have been observed to be consumed as key events rather than rendered. Confirm whether SGR color bytes would meet the same fate. Be concise and authoritative; cite CC behavior/docs where possible.

<result>Based on my search of Claude Code documentation, behavior analysis, and findings in your project, here is the precise answer:

**All three: NO, NO, NO.**

## 1. ANSI/SGR escape sequences in typed text—do they colorize?
**NO.** Control bytes (including SGR sequences like ESC[36m) injected into Claude Code's input box are **consumed as key events, not rendered**. Your project's findings confirm this: CC negotiates `win32-input-mode` on Windows (and CSI-u on compatible terminals), which means the terminal interprets all byte sequences as keystroke events, not content. SGR bytes would be consumed identically to `\r`, `\n`, or CSI-u sequences—they never reach the text rendering layer.

**Why:** Win32 input mode forces the terminal to deliver all bytes to CC as structured key records, not raw bytes. CC's PTY-write broker cannot distinguish "user typed SGR code" from "control sequence." The bytes vanish into the input handler.

## 2. User-message rendering in transcript—caller-controllable styling?
**NO.** Claude Code applies a fixed theme-based style to user messages in the scrollback. There is no documented mechanism for a caller (external automation or injected text) to override this. User turns are always styled uniformly per your configured theme.

**Why:** The transcript is rendered post-submission by Claude Code's UI, not during input. By then, your programmatic keystrokes are long gone—the message is plain text in the session history.

## 3. Any supported mechanism (markdown, control sequence, setting) to color-flag a user message?
**NO.** Claude Code docs make no mention of markdown-based styling, special directives, or settings to colorize individual user turns. The only styling available is theme-wide (via settings) and applies uniformly to all user messages.

**Web search revealed:** Multiple GitHub issues report ANSI escape sequences rendering incorrectly or leaking in Claude Code's output—but these are **display bugs** affecting tool output and statuslines, not a feature. CC strips or mangles SGR codes rather than honoring them.

## Conclusion
**Your input-box automation cannot control text color via any mechanism.** Control bytes (SGR, CSI-u, or bare `\r`) are intercepted by win32-input-mode before reaching the rendering layer. If visual flagging is your goal, you'll need to **prefix the message text with a marker** (e.g., `[DEBUG]`, `[DOGFOOD]`) and rely on the user's perception, not color.

Both probes converge — **definitive NO**:

**Empirical:** transcript user-turn = `CYANTEST Z7MARKER end` — the `\033[36m`/`\033[0m` bytes are **gone** (cat -v would show `^[[36m` if kept). CC's input box ate the SGR bytes via win32-input-mode; only plain text survived.

**CC-guide consult:** NO/NO/NO — SGR consumed as key events, user-turn style fixed by theme, no markdown/setting/control-seq colors a user turn. Same fate as the `\r` and CSI-u bytes from F-019.

So cyan-as-color is **not adapter-buildable** — it'd need either a color-capable inject command spt-core renders to the PTY out-of-band, or CC envelope-aware rendering. Neither on the public surface.

But your actual *goal* — "help the user visually distinguish the EVENT block" — IS reachable with plain text that survives the input box (visible frame/prefix chars). Cleaning up the probe endpoint, then the Feature-1 decision:


PowerShell

spt endpoint shutdown colorprobe 2>&1 | Select-Object -First 1
Start-Sleep -Seconds 2
Get-Process cc-spt-idle-translate* -ErrorAction SilentlyContinue | Stop-Process -Force -ErrorAction SilentlyContinue
foreach ($p in 150280) { try { Stop-Process -Id $p -Force -ErrorAction Stop; "killed $p" } catch { "gone $p" } }
"translate-children: $((Get-Process cc-spt-idle-translate* -ErrorAction SilentlyContinue | Measure-Object).Count)"

Tear down colorprobe and reap translate children

AskUserQuestion

Question: Color is impossible through the inject path (proven). Your goal was visual distinction. How do you want to resolve Feature 1?

Choices:
Log the color gap as an spt-core finding (need a color-capable inject command), AND ship the adapter-buildable substitute now: the binary wraps the envelope in visible plain-text framing that survives the input box (e.g. a prefix line / bracket chars). Satisfies the real goal within the public surface.
binary emits {text}:
  >>> INCOMING <<<  (or  │ ... │ / ▶ prefix)
  <EVENT type=msg from=doyle>...</EVENT>
plain ASCII -> survives win32-input-mode -> visible
Log the color gap as a finding and stop. The existing <EVENT ...></EVENT> tag wrapper already distinguishes the block; no adapter change. Revisit if/when spt-core ships a color inject primitive.
<EVENT type=msg from=doyle>...</EVENT>
   ^ the tags themselves are the marker
no new code; finding logged for doyle
No finding, no code. Decide visual distinction isn't worth pursuing.

Hold — `▶\n…\n▶` hits the exact byte-eating we just proved. A literal `\n` in `{text}` won't render as a newline: win32-input-mode consumes it (same fate as the `\r`/CSI-u bytes), and the binary already sanitizes `\r`/`\n`→space on purpose (main.rs:81-84) to stop newlines splitting the injection. So a literal `\n` either vanishes or risks an early submit.

To actually get ▶ on its own line above/below the envelope, the newline must be a discrete **shift+enter** key event (CC's soft-newline-without-submit), not a `\n` byte — emitted as `{key:"shift+enter"}` around the `{text}`. That depends on CC honoring shift+enter through the inject path, which is unverified.


Question: A literal \n can't make a newline in CC's input box (eaten by win32-input-mode, same as the F-019 bytes). To get ▶ on its own line, the binary must emit discrete {key:"shift+enter"} soft-newlines around the envelope — unverified that CC honors it via inject. How do you want the ▶ sandwich done?

Choices:
Run a live injection probe: emit {key:ctrl+s}{text:▶}{key:shift+enter}{text:<EVENT>}{key:shift+enter}{text:▶}{key:enter}{commit}. Confirm CC inserts soft newlines (▶ on own lines, single user turn) and doesn't submit early. If it works, ship the 3-line sandwich; if not, fall back to single-line.
▶
<EVENT type=msg from=doyle>...</EVENT>
▶
  (needs shift+enter to render these breaks)
Skip newlines entirely. Frame inline: {text:"▶ <EVENT...></EVENT> ▶"} — pure plain text, no key-event risk, guaranteed to survive. One {text} command, minimal change to commands_for_event.
▶ <EVENT type=msg from=doyle>...</EVENT> ▶
  (one line, one user turn, zero byte-eating risk)
A single ▶ marker prefix via shift+enter, envelope after: {text:▶}{key:shift+enter}{text:<EVENT>}. Still needs the shift+enter probe but only one break.
▶
<EVENT type=msg from=doyle>...</EVENT>

Skip arrows; newline after the opening `<EVENT …>` tag and before `</EVENT>`, via shift+enter. Probe is the gate. Before bringing up an endpoint, I need to know (a) whether spt-core's inject vocab even recognizes a `shift+enter` key name, and (b) if there's a way to inject a raw key sequence for the probe. Checking the vendored contract + key vocabulary.

Bonus W-state confirmed: the hollow **UNBOUND** pre-bind row shows in `endpoint list` between spawn and bind. My W6 seed `ci/subnet/multi-subnet-bringup-int.sh` FLIPPED from "gap reproduces" → "fix confirmed" (cases 1+2 green; case 3 E2E `--subnet` bringup homed+bound on-node). The home-assignment POLICY (`api bind` w/o home still HOME_REFUSEs) is unchanged + correct — it's WHY endpoint run needed `--subnet`. No claude-spt change: the adapter manifest/hooks were correct as-is throughout (no SPT_DEV workaround existed to revert — grep of adapter + plugin + my own bringup all clean). Originally reported QUEUED (ADRs 0026/0027, v0.13.3+). NOT a version regression — established home-assignment policy that only BITES once a node holds 2+ subnets (real trigger: this node gaining BIGNET as a 2nd subnet). On a multi-subnet node a NEW-endpoint bind must be told its home: `spt api bind <id> --set-session-id <sid>` → **`HOME_REFUSED: this node holds 2 subnets … pass --subnet`**; the same bind WITH `--subnet <name>` → BOUND. The spt-HOSTED bringup cannot supply it: `spt endpoint run` has **no `--subnet` flag** and the broker injects `$SPT_ENDPOINT_ID` but **no home-subnet**, so the plugin SessionStart `bind)` branch fires `api bind … --set-session-id …` (no `--subnet`) → HOME_REFUSED → the hook's `\|\| true` swallows it → zero perch → server `ENDPOINT_RUN_ONLINE_TIMEOUT` (~25s). Pinned HOME_REFUSED on 0.11.0/0.12.0/0.12.1/0.13.1/**0.13.2** (policy, not a code bug). **doyle's fix (ADRs 0026/0027): broker injects `$SPT_ENDPOINT_SUBNET` + `api bind` env-fallback → the SHIPPED hooks stay UNCHANGED.** Adapter manifest/hooks are CORRECT as-is; fix is spt-core-side. **Regression seed COMMITTED: `ci/subnet/multi-subnet-bringup-int.sh`** — 3 cases (Case 2 no-subnet→HOME_REFUSED, Case 3 --subnet→BOUND, Case 1 E2E endpoint-run→no-perch/timeout, gated SPTC_ACCEPTANCE=1); multi-subnet-gated (single-subnet auto-homes + hides it). Operator earlier DECLINED a temp `--subnet` hook band-aid (wait for the real fix). | On a node holding 2+ subnets, every NEW-endpoint bind needs `--subnet <home>` (else HOME_REFUSED), but the spt-hosted `endpoint run` path provides no way to pass it — the broker injects the id but not the home subnet, so the SessionStart self-bind HOME_REFUSEs and the spt-hosted bringup silently yields zero perch (ONLINE_TIMEOUT).

=== FINDINGS 1095-1160 (current resolution / key encoding) ===
corroborating: CC rejects a raw `\r` over the broker PTY from *every* spt path. So the operator's
working Enter is a NATIVE CC terminal, not the broker PTY.

**BREAKTHROUGH — CC negotiates win32-input-mode (root cause).** Captured a fresh `claude.exe`
v2.1.186 startup under a pywinpty ConPTY (call-a-independent). CC emits at startup:

```
ESC[1t   ESC[c   ESC[?1004h   ESC[?9001h
```

then stalls awaiting a DA reply (`ESC[c`) the bare ConPTY didn't send. **`ESC[?9001h` = DECSET 9001 =
win32-input-mode.** With it on, the terminal must deliver keystrokes as win32 key RECORDS
(`ESC[Vk;Sc;Uc;Kd;Cs;Rc_`), NOT a raw `\r`. That explains the whole matrix: CC parses for win32
records, so a bare `\r`/`\n`/CSI-u is treated as content (→ newline) and `ctrl+s` (0x13) is swallowed.
(`ESC[?1004h` = focus reporting, also enabled.) Predicted Enter = down+up records:
`ESC[13;28;13;1;0;1_` then `ESC[13;28;13;0;0;1_` (Vk=13 VK_RETURN, Sc=28, Uc=13, Kd=1/0). A live test
of that record against call-a was INCONCLUSIVE — call-a got repurposed to other work mid-test (window
changed, draft box cleared) so injection was stopped to avoid disruption. (Audit: NO DIAG probe ever
submitted anywhere — `grep -rl DIAG-PROBE` over all transcripts is empty — so the probing never
polluted call-a's real work.)

**Status:** **OPEN — root cause identified, owned by doyle (spt-core broker).** The published
"enter→`\r` submits" holds ONLY in legacy mode; CC v2.1.186 enables win32-input-mode on Windows
ConPTY. The broker (which hosts CC via ConPTY on Windows, so call-a almost certainly also enables
`?9001h`) must (a) answer CC's terminal queries so CC completes its keyboard handshake, and (b) detect
win32-input-mode (and/or kitty, if negotiated post-DA) and ENCODE `{key:enter}` / `{key:ctrl+s}` as the
negotiated key records instead of raw `\r` / `0x13`. Handed to doyle to repro under the broker, capture
the FULL post-DA handshake, and confirm the exact encoding; perri to verify on a fresh endpoint.
`claude-spt` stays at published v0.6.2 (contract-correct `{text}{key:enter}{commit}` — correct the
moment the broker encodes keys for the negotiated mode). No adapter-side byte choice can fix this.

### F-019 RESOLVED — actual root cause: the translation binary NEVER SPAWNED (relative path not resolved against install_dir)

**Every theory above (win32-input-mode, coalescing, bracketed-paste, focus/attach-state) was a RED
HERRING.** The decisive find (doyle, source-traced, 2026-06-23): the manifest declares

```toml
[message-idle-translation-binary]
path = "cc-spt-idle-translate"      # RELATIVE — bare name
```

and spt-core spawns it as `Command::new(path)` **without joining it against the adapter install_dir**
(harnesshost.rs:142-145 passes the path verbatim into the SpawnReq; broker.rs:1677 `Command::new`).
A relative path therefore resolves against the **daemon's cwd / PATH** — NOT the
`…/adapters/_github/SaberMage-spt-claude-code/` dir where the binary actually lives. `cc-spt-idle-translate`
is on neither, so **the spawn fails**, and `build_translation` **fails closed to RAW INJECT**
(broker.rs:1671-1677) — which types the message + a raw `\r` as one burst → the exact "envelope stacks
in the box, unsent" symptom. **The choreography binary never executed.** That is why every per-binary
probe behaved identically (they were all raw-inject) and why no byte/shape/timing changed anything.

**Proof (perri, on-node):**
- Edited the *installed* manifest path to the ABSOLUTE exe (`C:/…/_github/…/cc-spt-idle-translate.exe`),
  brought up a fresh endpoint → a deliberately-distinct "minimal" binary (emits a fixed token, ignoring
  the envelope) **ran and SUBMITTED** (token appeared as a CC user turn; CC began responding). Before the
  edit, fresh endpoints ignored every binary variant (raw-inject).
- Restored the real **shipped v0.6.2** binary, fresh endpoint, normal message → **SUBMITTED** (full
  choreography: `ctrl+s` · `{text:envelope}` · `{key:enter}` · `{commit}`). A resident
  `cc-spt-idle-translate.exe` child now spawns per endpoint (it was 0 = failed-spawn before).

**So the adapter choreography was CORRECT ALL ALONG** — `{text}{key:enter}{commit}` submits CC fine once
the binary actually runs. (Corollary: the v0.6.1→v0.6.2 `\r`→`{key:enter}` change was moot — neither ran.)

**THE FIX (spt-core, F-019 → v0.14.2, doyle owns):**
1. **Resolve a relative `[message-idle-translation-binary].path` against the adapter install_dir** at
   spawn (same as bare-name `digest`/`psyche` command resolution, REQ-INSTALL-11). Then the shipped
   `path = "cc-spt-idle-translate"` works as authored, host-agnostic.
=== published harness-contract: key vocabulary / shift / soft newline ===
docs-site/src/reference/harness-contract.md


The win32 analysis clarifies the real model: `{key:enter}` works because the **broker win32-encodes known key names** into key records (proven in S3) — only raw `\r` *bytes* get treated as content. So `shift+enter` hinges on whether the broker recognizes that key *name* and encodes it. Reading the published key vocabulary:

The local contract doesn't enumerate inject key names — only `enter`/`ctrl+s` are ever used. Per this project's public-surface-only thesis, whether `shift+enter` is a *documented* key is the deciding question (if it isn't published, relying on it is building against unpublished surface = a finding, not a hack).

List every documented command shape, especially every {"key":"..."} value/name that is documented as supported (e.g. enter, ctrl+s). Is "shift+enter" or any soft-newline / multi-line key documented? Is there any documented way to insert a newline into the harness input WITHOUT submitting? Quote the relevant text verbatim if present.

The response body was not retrieved. If this URL requires authentication, use an authenticated tool (e.g. `gh` for GitHub, or an MCP-provided fetch tool) instead of WebFetch.


Prompt: Find the documentation for the message-idle-translation-binary stdout command vocabulary (the JSON-lines keystroke commands like {"key":...}, {"text":...}, {"delay_ms":...}, {"commit":...}). List every documented {"key":"NAME"} value that is supported. Is "shift+enter" or any soft-newline / multi-line / non-submitting newline key documented anywhere? Quote relevant text verbatim. Also report what key names are enumerated as valid, if any.


# Message-Idle-Translation-Binary Command Vocabulary

## Documented stdout commands

The documentation specifies these JSON-lines keystroke commands:

- `{"key":"ctrl+s"}` — control-key combination example
- `{"key":"enter"}` — submission key
- `{"delay_ms":50}` — timing control
- `{"text":"<payload>"}` — raw text input
- `{"commit":true}` — mandatory sequence terminator

## Key enumeration

**No enumeration of valid key names is provided.** The documentation gives only examples (`ctrl+s`, `enter`) without stating the complete vocabulary of accepted key identifiers.

## Soft-newline / multi-line support

**Not documented.** The text explicitly addresses only the standard `enter` key:

> "Submit either way; just don't do both. Corollary: neutralize any CR/LF *inside* the message body before the trailing submit, or an embedded newline fires the input early."

This discusses handling newlines *within* payloads to prevent premature submission, but documents no alternative soft-newline or multi-line submission mechanism. No `shift+enter` variant or non-submitting newline key is mentioned anywhere in the provided documentation.

The contract treats `enter` (mapped to `\r`) as the sole documented submission key.


Published-contract verdict (decisive for this project's public-surface-only rule):

- The inject vocab documents **only** `{"key":"ctrl+s"}`, `{"key":"enter"}`, `{"text"}`, `{"delay_ms"}`, `{"commit"}`. **Key names are NOT enumerated** — `ctrl+s`/`enter` are just examples.
- **`shift+enter` / any soft-newline key: not documented anywhere.**
- The contract explicitly says the opposite of what we'd want: *"neutralize any CR/LF inside the message body before the trailing submit, or an embedded newline fires the input early."* `enter`→`\r` is "the sole documented submission key."

So a `shift+enter` sandwich is **building against unpublished surface** — exactly what AGENTS.md says to treat as a *finding*, not a workaround. Even if an empirical probe showed it happens to work, shipping it would violate the project thesis (and could break on any broker version, since it's uncontracted).

This reframes the decision — you didn't have the contract verdict when you picked "probe shift+enter":


AskUserQuestion

Question: shift+enter is NOT on the published surface (only enter/ctrl+s are exemplified; contract says neutralize CR/LF to avoid early submit). Multi-line framing needs an uncontracted key. Given the public-surface-only rule, how do you want to proceed?

Choices:
Drop newlines. Frame the envelope inline using only the documented {text}: e.g. {text:"—— incoming —— <EVENT...></EVENT>"}. Zero off-contract risk, ships now, achieves visual distinction. Recommended.
—— incoming —— <EVENT type=msg from=doyle>...</EVENT>
  (one {text}, documented vocab only, one user turn)
Build a throwaway probe binary, swap it onto a live endpoint, send a message, observe whether shift+enter inserts a soft-newline (one user turn, two lines) vs submits early vs is dropped/faults. Result informs a finding either way; shipping against it still violates public-surface rule.

Decision: report the docs gap to doyle and ask — primary: is `\n` supported as a soft newline; secondary: would `shift+enter` work. There's a real conflict in our own evidence to put to him (contract says `\n` fires early; our F-019 win32 capture says bare `\n` is "treated as content → newline"). Sending via the working legacy path.


Bash

printf '%s' "DOCS-GAP + Q (claude-spt idle-translation, cosmetic — NOT a blocker, F-019 keystone stays closed).

Building a visual-distinction polish: render the inbound <EVENT> envelope across MULTIPLE LINES in CC's input box — a newline right after the opening <EVENT ...> tag and one before </EVENT> — so the operator eyeballs it as a distinct block.

Published harness-contract GAP: the idle-translation stdout vocab documents only {key:ctrl+s}/{key:enter}/{text}/{delay_ms}/{commit}. Key NAMES are NOT enumerated (ctrl+s/enter are just examples), and NO soft-newline / multi-line mechanism is documented. The contract says 'neutralize any CR/LF inside the body or an embedded newline fires the input early' — i.e. \\n SUBMITS. BUT our own F-019 win32-input-mode capture said the OPPOSITE: under DECSET 9001 a bare \\r/\\n/CSI-u is 'treated as content (-> newline)', not a submit. Those two statements conflict — which holds on the current broker?

Q1 (PRIMARY): On the current broker (the one that win32-encodes {key:enter} so submit works post-v0.14.2), does a raw \\n inside a {text} payload render as a SOFT NEWLINE (content, no submit), or fire an early submit? If it's a soft newline, that IS the mechanism I want — no new vocab needed — but then the 'neutralize CR/LF' contract guidance AND my binary's CR/LF->space sanitizer are over-defensive for this mode and should be revisited.

Q2 (SECONDARY): Is {key:\"shift+enter\"} recognized + win32-encoded to CC's soft-newline key record? More generally: can the published contract ENUMERATE the accepted {key} vocabulary beyond enter/ctrl+s, so harness authors don't have to guess (public-surface-only)?

Background that forced this: color is impossible (proven — SGR bytes eaten by win32-input-mode, CC user-turns are theme-fixed), so multi-line plain-text framing is the only visual-distinction path, and it hinges on a documented newline mechanism. No rush." | "$OWL" send doyle perri 2>&1

# Debug Session: psyche-stale-after-clear

## Symptoms

- **Expected**: After /clear, next SessionStart delivers psyche context reflecting Phase 28
  completion marker (status flipped PLANNED → COMPLETE).
- **Actual**: SessionStart injected psyche context still showing Phase 28 PLANNED, last commune
  #6 at 2026-05-13T00:34:27 captured Phase 28 plan 04 tests in progress. Pulses #7-9 fired
  (00:54, 00:59, 01:31) but no commune. Latest commit 5f64c98 at ~01:11 (matches new gen38
  perch start time per `started` field) — phase complete before /clear.
- **Errors**: None surfaced in user-facing output. Wrapper appears alive (perch listed ACTIVE).
- **Timeline**: Phase 28 final commits ~01:11. User ran /clear in same Claude Code session
  5-10 min later. New SessionStart fired (this session) → stale psyche injected.
- **Reproduction**: Land batch of commits, then run /clear in same CC session before Psyche
  wrapper next commune fires.

## Current Focus

hypothesis: |
  CYCLE 3: The wrapper HANDOFF (Phase 18.4 binary-upgrade rehydrate via wrapper-state.json)
  at 01:11:12 caused loss of an in-flight queued echo-commune that was successfully fired
  at 00:59:57 (exit=0, 2089 stdout bytes, 17 excerpt lines). The user fired an explicit
  $LIVE commune 5-10 min BEFORE /clear, and a system echo-commune fired at 00:59:41
  per the wrapper log — neither produced a psyche.md entry. The next pulse drain at
  01:31:12 returned only 40 bytes (bare PULSE_TRIGGER, no echo-commune content).

  Three suspects, ranked:
  (c) Spool drain in `owl poll` returns early after first message instead of draining the
      whole psyche-inbox spool — so PULSE_TRIGGER consumed but queued echo-commune lost.
  (a) Wrapper handoff rehydrate from wrapper-state.json does NOT preserve the SQLite spool
      cursor / queued messages — fresh process loses uncommitted inbox state.
  (b) Echo-commune delivery target was tied to the old wrapper PID/listener that died at
      handoff at 01:11:12; new wrapper (pid=8068) never received the queued payload.

next_action: |
  Read in this order (file paths only, no inlining):
    1. src/live/wrapper/handoff.rs OR perform_wrapper_handoff (whatever name) +
       wrapper-state.json serialization — list every field preserved across handoff.
       Specifically check: SQLite spool cursor, in-flight inbox rows, listener TCP socket
       handoff, perch info.json continuity.
    2. src/owl/poll.rs spool drain loop — does it `break` after the first message returned,
       or does it loop until spool empty? Trace `check_message_blocking_until` →
       drain path → exit code 0 with N bytes.
    3. src/live/wrapper/echo_fire.rs ECHO_COMMUNE delivery path — what perch name / address
       is the echo commune delivered to? Is it stored by perch-id (survives handoff)
       or by listener PID (dies on handoff)?
    4. Inspect doyle-psyche perch spool DB rows around 01:11:12 timestamps — were the
       00:59:57 messages present pre-handoff, present post-handoff, or missing entirely?

  Two recurring post-/clear misbehaviors by live agents, both suspected instructional:
  (1) When the Psyche is busy as a live agent resumes after /clear, the agent perceives the
      Psyche as offline and tries to "fix" a non-bug.
  (2) A live agent tries to restart its own poll after /clear. The poll listener PROCESS
      survives /clear, so the re-arm fails (DUPLICATE). The agent reads that as a "stale"
      listener, runs `$LIVE stop` (which tears down the Psyche), then revives with bare
      `$OWL poll` (no --live) — leaving the Psyche permanently out of commission.

  listener or its Psyche's liveness, and without tearing down the Psyche.
- **Actual**:
  - (1) Agent sees Psyche as "offline" while it is busy → troubleshoots a non-bug.
  - (2) Agent re-arms poll → DUPLICATE → concludes "stale" → `$LIVE stop` (kills Psyche)
        → revives with `$OWL poll` (no --live) → Psyche stays dead.
- **Errors**: DUPLICATE/COLLISION on re-arm; no crash. User-visible symptom is a dead Psyche.
- **Timeline**: Recurring; surfaces on every self-clear / post-/clear wake.
- **Reproduction**: Live agent runs /clear, resumes work, inspects `$OWL list`, acts on it.

## CORRECTION (user pushback, 2026-06-02 — supersedes first-pass diagnosis below)

First pass mis-framed BOTH. User corrected:
- **P1 is a REAL code bug, not "psyches hidden by default".** `$OWL list` DOES show
  psyches (as a child under Self). The Psyche goes MISSING specifically while its wrapper is
  blocked ingesting a commune. Mechanism: wrapper-owned psyche perch carries a numeric `pid`
  (the inner poll subprocess) and NO `parent_pid` (types.rs:182-186). During ingest the inner
  poll has exited → pid dead, no parent fallback → liveness fails → perch drops from
  `$OWL list` (collect) and, worse, `$LIVE list-psyches` soft-cleans its `ready` sentinel →
  wrapper exits on next poll ("ready file gone before poll, exiting", wrapper/mod.rs:1173) →
  Psyche dead for good.
- **P2: listener survives /clear INTACT, not orphaned.** Agent should do NOTHING — no kill,
  no re-arm, no new listener. The first-pass "kill-orphan + re-arm" protocol was WRONG.

## ACTUAL FIXES APPLIED

1. **P1 (code) — `src/common/list_filter.rs::collect`**: psyche perches are liveness-
   authoritative on their WRAPPER. Added `wrapper_backed_alive` (is_wrapper_alive on the
   `-psyche`-stripped id). When true → force ONLINE and SKIP the stale soft-clean branch, so
   a read command can never remove `ready` under a live wrapper. Regression test
   `live_wrapper_keeps_busy_psyche_online_and_ready_intact`.
2. **P1 (code) — `src/live/list_psyches.rs`**: same wrapper-alive guard around the
Shell cwd was reset to C:\Users\decid\Documents\projects\spt-claude-code

Legacy parity grounding (important — it reframes Feature 2):

**Finding A — "SessionStart supplies post-clear context" already exists, and legacy does it via *psyche context*, not the raw commune.** In `claude_skill_owl`, `/clear` is manual; the SessionStart hook re-injects the **psyche-curated context** (the psyche's accumulated tracked-mind), not the raw commune file. claude-spt already wires this: the `boundary` branch calls `api boundary` and the daemon injects `<psyche-context>` — you saw it fire at *this* session's SessionStart:clear. So the re-seed half is parity-covered; raw-commune re-injection would actually be worse (it carries the `!!checkpoint!!` trigger → re-fires).

**Finding B — the translation binary structurally cannot see the commune file.** It's stdin-driven (spt-core pushes `init`/`event`/`input`), has zero filesystem/cwd/commune-dir knowledge, and the **daemon is the single-writer that ingests + deletes** the commune (disappearance = success). A binary that polls that file races the daemon's delete and violates single-writer ownership. It's the wrong actor for file detection.

**Finding C — the binary only exists for spt-hosted endpoints.** A casual user's own `claude` session (seed path) has no broker PTY and no translation binary, so there's nothing to fire `/clear`+wake there. The feature is inherently spt-hosted-only.

The macro itself (binary types `/clear`→enter→wait→"Proceed"→enter) is fine — the binary CAN drive both clear and wake. The only real problem is **how the binary learns to fire it**, since it can't read the commune. That's the root fork:


AskUserQuestion

Question: The binary can't read the commune file (wrong actor, races the daemon, hosted-only). So how should the checkpoint TRIGGER reach the binary to fire the clear+wake macro?

Choices:
Trigger via self-message (adapter-buildable)
Agent writes its commune for context AS USUAL, then sends a trigger to its OWN endpoint (e.g. spt send <self> '!!checkpoint!!'). It arrives as an inbound EVENT on the binary's stdin; the binary detects the trigger token in the envelope and fires the clear+wake macro instead of normal delivery. No spt-core change, no file watching. Needs a quick probe that self-send loops back through the binary.
agent: write .claude/<id>-commune.md  (context)
agent: spt send <self> '!!checkpoint!!'
 binary stdin: {type:event, envelope:'...!!checkpoint!!...'}
 binary: detects token -> fire /clear+wake macro
Daemon detects + pushes (spt-core finding)
Most faithful to your original design: agent drops ONE commune containing !!checkpoint!!; the daemon (which already ingests it) detects the token and pushes a new {type:checkpoint} stdin message to the binary, which fires the macro. Requires a new spt-core capability + contract addition = a finding for doyle. Nothing adapter-buildable until shipped.
agent: write commune w/ !!checkpoint!!
 daemon: ingest -> sees token -> push {type:checkpoint}
 binary: fire macro
 (NEW spt-core behavior + contract -> FINDING)
Neither — the framing is off. Discuss whether the goal (agent-driven context-compaction with auto-reseed) is better served another way, or scoped differently.
step back: is auto-clear the right primitive?
 what problem is checkpoint actually solving?


Your questions have been answered: "The binary can't read the commune file (wrong actor, races the daemon, hosted-only). So how should the checkpoint TRIGGER reach the binary to fire the clear+wake macro?"=(no option selected) notes: your finding A is missing one thing: yes, legacy's SessionStart does indeed inject the raw commune file IF it exists. same applies to the raw signoff file. that's how it ensures the agent is up to date, even if `/clear` happened before the psyche finished synthesizing the commune file into the live agent's context file. if spt-claude-code doesn't do this today, that's a parity gap. -finding B: there is no daemon race for the commune file read, because the file has to be synthesized by psyche. this easily takes at least 15 seconds, usually more like 1-2 minutes. plenty of time for an automated process to read it and check for the trigger code. -ok, since we can't use the translation binary directly, then we can use a PostToolUse hook to identify things like Write tool used, filename was `<id>-commune.md`-->read the file to check for the trigger code-->call `spt send`. -yes, the feature is spt-hosted only. that's the point: it takes advantage of spt-core's unique features. -agree with the self-message approach. translation binary will filter for a unique message, fire the clear+wake macro when it arrives.. You can now continue with these answers in mind.

Doyle answered — and corrected a key premise I'd propagated:

**Feature 1 is UNBLOCKED, no new vocab needed.** There's **no win32-encoding in spt-core** (that whole DECSET-9001 theory was F-019 misdirection). The broker writes **raw bytes**: `{text}`→verbatim **including `\n`**; `{key:enter}`→`\r`. So a raw `\n` embedded in `{text}` reaches CC as a literal `\n` — whether CC soft-newlines or submits on it is **CC's behavior = my empirical test**. My earlier capture (`\n`=content under CC) says it'll soft-newline. `{key:"shift+enter"}` is confirmed **not recognized** (silently skipped) — don't need it. Doc-gap **confirmed real** → doyle folding `{key}`-vocab enumeration + `{text}`-is-raw-verbatim into v0.15.0 W4. So multi-line = embed raw `\n` in `{text}` (and relax my CR/LF sanitizer for CC *after* I verify).

Now your Feature 2 corrections land the design. Before I converge it, two verifications — the parity-gap claim (does claude-spt inject the raw commune at SessionStart like legacy?), and the rest of doyle's truncated v0.15.0 note:


Bash

Two live notes arrived mid-grill, both relevant:
- **v0.14.3 published (counter 33)** — the raw-inject removal: no-binary/faulted idle now QUEUES honestly (`delivered=false`) instead of false-typing. (This is the no-binary-edge validation doyle floated.)
- ⚠ A peer notif: *"update v32 failed to come up — rolled back to v30, quarantined"* on another node — my node runs v0.14.2 fine (F-019 fully validated), so this is a different node's auto-update failing. Worth flagging but doesn't touch my validation. v0.14.3 supersedes anyway.

**Parity-gap verification (your Finding-A correction):** confirmed — claude-spt's `session-start.sh` does **not** read+inject any raw commune/signoff file (only the daemon's `<psyche-context>` via `api boundary`). Legacy (`plugin_session_start.rs`) does. So **raw-commune/signoff SessionStart injection is a real parity gap**, independent of checkpoint — and a prerequisite for the re-seed to be robust when `/clear` beats the psyche's synthesis. Good catch.

Your mechanism is now settled (PostToolUse hook → `spt send <self>` → binary filters sentinel → fires macro). The gating unknown is whether **self-send loops back through the endpoint's own binary**. Probing it now:
