## Current Focus

hypothesis: RESOLVED — this is NOT a bug. The 2769efb fix works correctly. The 19:51:30 echo did execute `claude -p --resume <self_uuid>` successfully, haiku responded with an empty `[COMMUNE][/COMMUNE]` (as the prompt instructs when nothing significant happened), and the empty-content check at src/owl/echo_commune.rs:138 + src/live/wrapper/claude.rs:458 correctly dropped it without delivering. No `[MSG] from=ECHO_COMMUNE` line means "nothing to commune about", not "delivery failed".
test: Reproduced echo-commune directly via `_echo-commune fb822094 todlando todlando-psyche` from project root with CLAUDE_CONFIG_DIR set. Result: exit=0, session jsonl gained a new `[COMMUNE]\n[/COMMUNE]` response, psyche inbox untouched. Matches the observed 19:51:30 behavior exactly.
expecting: N/A — root cause identified as intended behavior, not a bug.
next_action: Return ROOT CAUSE FOUND with recommendation to improve log observability so empty-commune cases are distinguishable from failure cases.

## Symptoms

expected: Echo commune spawned at log line 96 should produce a `[MSG] from=ECHO_COMMUNE` line with actual content (like line 15 did for the earlier successful echo).
actual: After `[19:51:30] [ECHO] spawned pid=38264` (line 96), no `[MSG] from=ECHO_COMMUNE` appears. Next activity is a PULSE_TRIGGER 20 minutes later at 20:11:31.
errors: None logged. No stderr. Echo process exited silently without producing deliverable output.
reproduction: Compare successful echo at lines 10-30 (pid=38024) vs failed echo at line 96+ (pid=38264). Same wrapper, same session gen=17, ~16 minutes apart.
started: Phase 18.6 Plan 02 just shipped echo-commune CWD fix (commit 2769efb). Live-fire verify outstanding.

## Eliminated

- hypothesis: 2769efb fix is broken / CWD lookup fails
  evidence: Repro `cd claude_skill_owl && CLAUDE_CONFIG_DIR=~/.ccs/instances/bigscreen claude -p --resume fb822094 ... <<< "test..."` → produced `[COMMUNE]test2[/COMMUNE]` successfully. Session lookup works when run from the wrapper's inherited CWD with the wrapper's inherited env.
  timestamp: 2026-04-19T22:25:00

- hypothesis: First echo "succeeded" because the foreground user session intercepted it via prompt-queue
  evidence: Initially noted that fb822094.jsonl line 78 showed a `queue-operation enqueue` and the haiku response at line 87 recorded `cwd=claude_skill_owl`. But the same pattern is observed in the standalone test repro run from a shell WITHOUT any foreground claude instance — claude -p --resume against a registered session always writes an "assistant" entry with the process's own cwd and queue ops are normal turn framing, not cross-session routing. Retracted.
  timestamp: 2026-04-19T22:35:00

- hypothesis: Rate-limit hit haiku at 19:51
  evidence: Rate-limit messages in todlando.log and doyle.log only appear starting 20:41 ("resets 10pm"). At 19:51 haiku had capacity. Also doyle's echo-commune at 20:20:51 succeeded with a 1740-byte delta — rate-limit was not yet active.

## Evidence

- timestamp: 2026-04-19T21:15:00
  checked: git log for 2769efb and current echo_commune.rs
  found: Fix commit 2769efb is present at HEAD. echo_commune.rs has no `current_dir()` call, absolute self_md path baked in prompt, `--add-dir <psyche_dir>` granted. Fix is deployed in v1.8.9 binary at `~/.ccs/instances/bigscreen/plugins/cache/cplugs/spt/1.8.9/owl.exe` (matches wrapper pid 14088 executable path).
  implication: The fix IS in effect at runtime; any failure is not a "fix didn't ship" issue.

- timestamp: 2026-04-19T21:20:00
  checked: owlery/todlando/info.json + session UUID discovery
  found: Self (todlando) session_id = fb822094-f6ae-42e7-88f4-7804855d01a2. Psyche (todlando-psyche) session_id = 19b78cd1-18b3-4496-8c44-acf13e0324e3.
  implication: Two distinct sessions — Self (registered under project-root encoding) and Psyche (registered under psyche_dir encoding). Echo-commune resumes Self, not Psyche.

- timestamp: 2026-04-19T21:30:00
  checked: `find ~/ -name "fb822094*"` + `find ~/ -name "19b78cd1*"`
  found: fb822094 → ONLY `~/.ccs/instances/bigscreen/projects/C--Users-decid-Documents-projects-claude-skill-owl/fb822094-*.jsonl`. 19b78cd1 → ONLY `~/.ccs/instances/bigscreen/projects/C--Users-decid-AppData-Local-spt-psyches-tracked/19b78cd1-*.jsonl`.
  implication: CCS is active. Both sessions are registered under the bigscreen instance, with the CWD-encoding matching the CWD of the spawning process. Self was registered from project-root CWD; Psyche was registered from psyche_dir CWD. For `claude -p --resume <self>` to find Self it needs CWD=project-root AND CLAUDE_CONFIG_DIR=~/.ccs/instances/bigscreen.

- timestamp: 2026-04-19T21:45:00
  checked: `echo $CLAUDE_CONFIG_DIR` in the session's ambient terminal; powershell query of wrapper pid 14088 env
  found: CLAUDE_CONFIG_DIR=C:\Users\decid\.ccs\instances\bigscreen in both the live shell and (presumably) the wrapper process — .ccs sets this env across all shells spawned inside its instance.
  implication: Wrapper inherits CLAUDE_CONFIG_DIR. _echo-commune inherits it (empty envs slice => inherit parent). claude subprocess inherits it. Resolution routes to ccs/bigscreen projects dir — which IS where fb822094 lives.

- timestamp: 2026-04-19T22:00:00
  checked: Direct repro — `cd claude_skill_owl && CLAUDE_CONFIG_DIR=~/.ccs/instances/bigscreen claude -p --resume fb822094 --model haiku ... <<< "test: [COMMUNE]hello[/COMMUNE]"`
  found: stdout = `[COMMUNE]hello[/COMMUNE]`. Exit=0.
  implication: The CWD + env + session combination works as designed. 2769efb fix does resolve the CWD/session lookup problem at the advertised layer.

- timestamp: 2026-04-19T22:05:00
  checked: Same repro with CLAUDE_CONFIG_DIR unset
  found: stdout = "No conversation found with session ID: fb822094..." (the original silent-bail signature).
  implication: CLAUDE_CONFIG_DIR is REQUIRED for the wrapper to find Self in a .ccs account. Confirms the 2769efb fix is necessary but ALSO requires the ambient CCS env to be inherited down the spawn chain.

- timestamp: 2026-04-19T22:10:00
  checked: Doyle's log + doyle's Self session location
  found: doyle's Self session c1a4dc0c is registered under vanilla `~/.claude/projects/C--Users-decid-Documents-projects-claude-skill-owl/` (NOT under .ccs). Doyle's echo-communes fired three times (19:38:49 / 19:59:49 / 20:20:51) all succeeded with substantial content.
  implication: Two concurrent wrappers in different Claude Code installs (vanilla vs .ccs bigscreen). Both worked when there was a real delta to report. Confirms the end-to-end fire path works for both vanilla and .ccs-scoped sessions.

- timestamp: 2026-04-19T22:25:00
  checked: Direct repro — `cd claude_skill_owl && export CLAUDE_CONFIG_DIR=...ccs/bigscreen && $OWL _echo-commune fb822094 todlando todlando-psyche`
  found: Exit=0. Psyche inbox (todlando-psyche/inbox/) empty. Session jsonl gained a new assistant entry: `"text":"[COMMUNE]\n[/COMMUNE]"` (empty COMMUNE content).
  implication: End-to-end subcommand works. Haiku returned an EMPTY commune because there was nothing significant to summarize. The empty-content check at echo_commune.rs:138 (and redundantly at parse_markers:458) correctly skips `deliver_body_anonymous`, so no `[MSG] from=ECHO_COMMUNE` appears in the wrapper log. This is intentional per the prompt contract ("If nothing significant happened, output an empty [COMMUNE][/COMMUNE]").

- timestamp: 2026-04-19T22:35:00
  checked: Context around todlando's 19:51:30 echo
  found: Preceding wrapper activity: 19:35:47 first echo delivered major content (v1.8.9 deploy announcement, CWD fix). 19:36:17 user sent a COMMUNE to psyche via $OWL. 19:36:41 psyche updated todlando.md to record gen17 bootstrap. 19:36:45 echo gate rejected (sentinel 23s fresh). 19:51:22 PULSE_TRIGGER → "Pulse 1 logged. State nominal." Between 19:36 and 19:51 there was no meaningful state change (same pending items, no new commits, same "awaiting live-fire verify" state). Haiku had nothing to report.
  implication: Empty commune at 19:51:30 is the correct behavior given the actual delta (~none).

## Resolution

root_cause: NOT A BUG. The 19:51:30 echo-commune executed correctly. The haiku child successfully resumed the Self session (fb822094) from the wrapper's inherited CWD (project root) and CCS env (CLAUDE_CONFIG_DIR=~/.ccs/instances/bigscreen). It produced `[COMMUNE][/COMMUNE]` (empty content) because nothing significant had changed in the 16-minute window between the first echo's delivery (which itself announced the v1.8.9 deploy + CWD fix) and the 19:51:30 fire. The empty-content filter at `src/owl/echo_commune.rs:138` (`if marker_type == "COMMUNE" && !content.is_empty()`) and `src/live/wrapper/claude.rs:458` (inside `parse_markers`) correctly skips delivery for empty communes, matching the prompt contract that instructs haiku to output `[COMMUNE][/COMMUNE]` when there is nothing to report. Doyle's concurrently-running wrapper produced substantial communes at 19:38:49 / 19:59:49 / 20:20:51 — proving the fire path works end-to-end when there IS a real delta.

fix: No code fix required. The original symptom (silent gap between `[ECHO] spawned pid=` and nothing) is operationally indistinguishable from the prior resolved bug (CWD mismatch → empty stdout → silent bail), which is the real observability gap. Recommended follow-up (NOT applied here — this session is find_root_cause_only):

  1. Add a positive log line in `fire_echo_commune_if_due` OR have the _echo-commune subcommand write a log entry to the wrapper's log so the operator can distinguish: (a) echo fired + delivered N-byte commune, (b) echo fired + empty commune (no delta), (c) echo fired + FAILED (session lookup / network / etc.). Currently only (a) is observable.

  2. Consider emitting `[ECHO] empty commune — no delta` from the wrapper perspective when the echo child exits but nothing was queued to the psyche inbox within a bounded window. This requires either the _echo-commune subcommand to write a sentinel file the wrapper polls, or the wrapper to check the perch inbox itself post-fire.

  3. Add a debug/diag log path inside echo_commune.rs itself that records to `logs_latest/{self_id}-echo.log` (or appends to the wrapper log via a shared path) so future "silent" incidents can be diagnosed without having to correlate against the Claude CLI's project-scoped session jsonls.

verification: (a) Direct repro of `_echo-commune` subcommand from the wrapper's expected CWD + env → exit=0, session jsonl gained empty-COMMUNE assistant turn, no psyche inbox write. Matches observed behavior exactly. (b) Doyle's three successful echoes in the same wall-clock window establish that the fire path works when content exists. (c) cross-checked `parse_markers` and the `if !content.is_empty()` guard in echo_commune.rs — empty commune is explicitly silently dropped by design.
