Commit 2d40baac (PR #2304) renamed `_ecc_*` -> `_clv2_*` but missed this
single call site. The launcher sources `scripts/lib/homunculus-dir.sh` which
only exports `_clv2_resolve_homunculus_dir`, so any user enabling the
observer (`observer.enabled: true`) gets:
start-observer.sh: line 40: _ecc_resolve_homunculus_dir: command not found
The hook (`observe.sh`) uses the correct name and writes observations, but
the lazy-start path fails silently via nohup, so the symptom is
"observations grow forever, no new instincts". Confirmed on
affaan-m/ECC@40927950c (HEAD of main).
Default `observer.enabled: false` masks the bug for new users. Opt-in
users hit it on first manual `start-observer.sh start` or first lazy-start
after enabling.
Fix: rename the single call to `_clv2_resolve_homunculus_dir` to match
the lib export and every other caller in the skill.
* chore(continuous-learning-v2): standardize shell shebangs to env bash
Three scripts under skills/continuous-learning-v2/ used the hardcoded
`#!/bin/bash` shebang while the other four already used the portable
`#!/usr/bin/env bash`:
- hooks/observe.sh (runs on every hook invocation)
- scripts/detect-project.sh
- agents/start-observer.sh
The hardcoded interpreter path fails to execute on systems where bash is
not installed at /bin/bash (NixOS, some Homebrew layouts, FreeBSD).
Standardize all three to `#!/usr/bin/env bash`, matching the repo-wide
majority convention, and add a regression test that asserts shebang
uniformity for every shell script in this skill so the inconsistency
cannot reappear.
Fixes#2303
* test(continuous-learning-v2): harden shebang test runner
Address review feedback on the shebang-consistency regression test:
- firstLine() now splits on /\r?\n/ so a script checked out with CRLF
line endings does not leave a trailing carriage return that would
break the shebang comparison on Windows.
- The test() helper now surfaces the full error (stack trace, not just
the message) on failure and writes pass/fail lines via
process.stdout/stderr so diagnostics are preserved.
* test(continuous-learning-v2): skip hidden dirs in shebang scan
The recursive shell-script scan now skips hidden directories (e.g. the
observer's runtime `.observer-tmp`). This keeps the shebang-consistency
check deterministic: only committed skill scripts are examined, and an
untracked local artifact left over from an observer run can no longer
cause a false failure.
* fix(observer): replace hardcoded sleep 2 with PID file poll in start-observer.sh
Fixes#2295
The previous `sleep 2` after launching the observer loop has two
problems: on slow filesystems or loaded systems 2 seconds may not be
enough, producing a false-negative on the subsequent PID file check; on
healthy systems it adds unnecessary latency.
Replace with a poll loop that exits as soon as the PID file appears:
for _i in $(seq 1 50); do [ -f "$PID_FILE" ] && break; sleep 0.2; done
50 × 0.2s = 10s max wait (vs the previous fixed 2s), but typical startup
returns within the first iteration. No behavior change in the success
path — only the wait strategy changes.
Tests: `node tests/run-all.js` 2891 passed / 0 failed; `npm run lint`,
`catalog:check`, `command-registry:check` all clean.
* test(observer): add regression guard for sleep-2 → PID-file poll (#2295)
Asserts start-observer.sh never reverts to the fixed `sleep 2` wait and
keeps the 50 × 0.2s `$PID_FILE` poll in place. Sits next to the existing
observer-loop invariant block in tests/hooks/hooks.test.js, matching the
repo's pattern of guarding shell-script invariants via source-content
assertions.
Without this, any future "cleanup" that reintroduces a fixed sleep would
silently regress the slow-filesystem fix from the previous commit.
* fix(observer): loosen poll-regression assertions and document failure-path latency (#2356 review)
Addresses CodeRabbit + Greptile feedback on PR #2356:
- tests/hooks/hooks.test.js: split the over-specific positive assertion
(which pinned the exact `for _i in $(seq 1 50); … sleep 0.2; done`
line) into three intent-based assertions — bounded iteration count,
early-exit on $PID_FILE, sub-second interval. Valid refactors (rename
loop var, switch to `while`, retune to 100 × 0.1s) no longer false-fail
while the `sleep 2` regression remains guarded.
- start-observer.sh: extend the inline comment to record the trade-off
Greptile flagged — a loop that crashes before writing $PID_FILE is now
detected in ~10s instead of ~2s. Healthy startups still return in
iteration 1.
Tests: node tests/run-all.js (Node v22.18.0) → 2892 passed / 0 failed.
- Redirect observer output to temp log before appending to main log
- Check temp log for confirmation/permission language immediately after start
- Fail closed with exit 2 if detected, preventing retry loops
* fix(continuous-learning-v2): observer background process crashes immediately
Three bugs prevent the observer from running:
1. Nested session detection: When launched from a Claude Code session,
the child process inherits CLAUDECODE env var, causing `claude` CLI
to refuse with "cannot be launched inside another session". Fix: unset
CLAUDECODE in the background process.
2. set -e kills the loop: The parent script's `set -e` is inherited by
the subshell. When `claude` exits non-zero (e.g. max turns reached),
the entire observer loop dies. Fix: `set +e` in the background process.
3. Subshell dies when parent exits: `( ... ) & disown` loses IO handles
when the parent shell exits, killing the background process. Fix: use
`nohup /bin/bash -c '...'` for full detachment, and `sleep & wait`
to allow SIGUSR1 to interrupt sleep without killing the process.
Additionally, the prompt for Haiku now includes the exact instinct file
format inline (YAML frontmatter with id/trigger/confidence/domain/source
fields), since the previous prompt referenced "the observer agent spec"
which Haiku could not actually read, resulting in instinct files that
the CLI parser could not parse.
* fix: address review feedback on observer process management
- Use `env` to pass variables to child process instead of quote-splicing,
avoiding shell injection risk from special chars in paths
- Add USR1_FIRED flag to prevent double analysis when SIGUSR1 interrupts
the sleep/wait cycle
- Track SLEEP_PID and kill it in both TERM trap and USR1 handler to
prevent orphaned sleep processes from accumulating
- Consolidate cleanup logic into a dedicated cleanup() function
* fix: guard PID file cleanup against race condition on restart
Only remove PID file in cleanup trap if it still belongs to the
current process, preventing a restarted observer from losing its
PID file when the old process exits.
- Add try-catch around readFileSync in validate-agents, validate-commands,
validate-skills to handle TOCTOU races and file read errors
- Add validate-hooks.js and all test suites to package.json test script
(was only running 4/5 validators and 0/4 test files)
- Fix shell variable injection in observe.sh: use os.environ instead of
interpolating $timestamp/$OBSERVATIONS_FILE into Python string literals
- Fix $? always being 0 in start-observer.sh: capture exit code before
conditional since `if !` inverts the status
- Add OLD_VERSION validation in release.sh and use pipe delimiter in sed
to avoid issues with slash-containing values
- Add jq dependency check in evaluate-session.sh before parsing config
- Sync .cursor/ copies of all modified shell scripts
Core library fixes:
- session-manager.js: wrap all statSync calls in try-catch to prevent
TOCTOU crashes when files are deleted between readdir and stat
- session-manager.js: use birthtime||ctime fallback for Linux compat
- session-manager.js: remove redundant existsSync before readFile
- utils.js: fix findFiles TOCTOU race on statSync inside readdir loop
Hook improvements:
- Add 1MB stdin buffer limits to all PostToolUse hooks to prevent
unbounded memory growth from large payloads
- suggest-compact.js: use fd-based atomic read+write for counter file
to reduce race window between concurrent invocations
- session-end.js: log when transcript file is missing, check
replaceInFile return value for failed timestamp updates
- start-observer.sh: log claude CLI failures instead of silently
swallowing them, check observations file exists before analysis
Test fixes:
- Fix blocking hook tests to send matching input (dev server command)
and expect correct exit code 2 instead of 1
