Addresses CodeRabbit review: the negative-only assertions could have
passed on an empty plan. Add a positive assertion that the non-foreign
'rules' path is still planned under .claude/rules/ecc so regression to
zero ops would fail loudly.
Completes the install-target matrix for Claude Code. Until now, ECC's
Claude support was home-scope only (~/.claude/) via the `claude` target.
This adds a project-scope counterpart (./.claude/) via a new
`claude-project` target so teams can install ECC per-repo without
contaminating ~/.claude/ — matching the existing project-scope adapters
for Cursor, Antigravity, Gemini, CodeBuddy, Joycode, and Zed.
Symmetric with `claude`:
- Same namespace under rules/ecc and skills/ecc
- Same docs/<locale> handling for --locale
- Same hooks placeholder substitution for hooks.json
- Reuses claude-home's destination-mapping logic 1:1
Use cases:
- Monorepos with multiple Flow-managed projects
- Teams that want ECC scoped per-project without touching ~/.claude/
- Per-project skill/rule isolation when global install isn't desirable
No breaking change: existing --target claude continues to route to
claude-home (user-scope) unchanged. New target is opt-in.
Tests
-----
- 4 new tests in tests/lib/install-targets.test.js
(root resolution, lookup-by-id, plan parity with claude, foreign-path filtering)
- All install-target regression guards (schema enum / SUPPORTED_INSTALL_TARGETS)
still pass
- End-to-end smoke: `--target claude-project --profile minimal --dry-run`
emits 359 ops with destinations rooted at <projectRoot>/.claude/ (parity
with --target claude which emits 359 ops rooted at ~/.claude/)
Salvages the useful harness-audit scoring work from #1989 while preserving the current hook registry and newer plugin install detection. Adds GitHub integration checks, conditional deploy-provider categories, dynamic applicable category metadata, and CODEOWNERS coverage.
Refresh the active 2.0 release surface for the affaan-m/ECC repo identity, update package/plugin/workflow launch metadata, and add an operator command center for release video, partner, sponsor, consulting, and social launch execution.
Generate the inline hook root resolver with single-quoted JavaScript literals so Windows Git Bash does not choke on nested escaped double quotes before Node starts. Refresh hooks.json and add regression coverage for parsed hook commands and installed hook manifests.
Two round-1 review findings in `tests/lib/session-bridge.test.js`,
both about test correctness rather than the underlying fix:
1. **greptile P1 + coderabbitai Major + cubic P2 (all three): concurrent-write test ran sequentially.**
The test spawned two child processes with two consecutive
`spawnSync` calls. Because `spawnSync` blocks until the child
exits, the second writer started *after* the first finished —
the two writers never overlapped, so the rename race the fix
targets was never actually exercised. The test would have passed
with the old broken `${target}.tmp` suffix.
Fix: introduce a one-off "race runner" helper that runs inside
its own subprocess and uses async `spawn` to start both writers
simultaneously. The runner waits for both to exit (the event
loop is local to the runner subprocess, so this stays compatible
with the synchronous test harness used elsewhere in this file)
and reports both exit codes plus stderrs on stdout. The test
then calls the runner via `spawnSync` and parses the result.
Both writer children now overlap for the duration of their 200
`writeBridgeAtomic` calls each, which is enough wall time to
reliably trigger the rename race against the pre-fix code.
Verified: with the fixed `${target}.${pid}.${nonce}.tmp` suffix,
the test passes; with the old fixed `${target}.tmp` suffix
reintroduced, it fails as expected (one writer hits ENOENT on
roughly half its rename calls).
2. **greptile P2 + cubic P3: `assert.throws` used a string as the second argument.**
Node deprecated passing a string as the second argument to
`assert.throws` years ago: the string is silently treated as
the assertion failure message (what to print when the function
does *not* throw) rather than as an error matcher. The check
passed for any thrown error, not just the rename failure.
Fix: pass a regex matcher as the second arg and keep the
explanatory text as the third. The regex matches `EISDIR`,
`EPERM`, `ENOTDIR`, or `ENOENT` because `renameSync` of a
regular tmp file onto an existing directory raises different
codes on Linux / macOS / BSD — making the matcher portable
across CI runners.
Test count unchanged at 14; `npm test` green; `npm run lint` clean.
The two helper files (`tests/__tmp_bridge_writer.js`,
`tests/__tmp_bridge_race_runner.js`) are written and unlinked
inside the test's try/finally so they never persist beyond the
test run.
Two regression tests pin down the previous two commits' atomic-rename
fixes:
1. **concurrent writes don't throw ENOENT or corrupt the file** —
spawns two child Node processes (`tests/__tmp_bridge_writer.js`
created in-test, cleaned up in finally) that each call
`writeBridgeAtomic(sid, …)` 200 times against the same session
ID with independent payloads. Asserts both subprocesses exit 0
(the previous implementation produced ENOENT on roughly 50% of
rename calls, all swallowed by the in-test catch) and the final
bridge file is parseable JSON belonging to one of the two writers
(last-writer-wins is fine; the contract is *no corruption* and
*no rename ENOENT*, not data preservation).
2. **tmp file cleanup on rename failure** — pre-creates a directory
at the target bridge path so `renameSync(tmp, target)` fails,
calls `writeBridgeAtomic`, asserts the call throws AND that no
tmp file with the writer's `pid.<nonce>.tmp` prefix is left
behind in `os.tmpdir()`. The previous code had no cleanup; the
fix's `try/catch + unlinkSync` keeps tmpdir from accumulating
orphan files across repeated rename failures.
The first test deliberately writes independent payloads from each
subprocess so this regression doesn't try to claim a property the
fix doesn't actually deliver (read-modify-write race in the caller
is a separate issue and out of scope per PR body).
Test count: 12 → 14 in `tests/lib/session-bridge.test.js`;
`npm test` green; `npm run lint` clean.
9 new test cases pin down the two previous commits' denylist
extensions. Each verifies both detection (validator exit non-zero +
the expected `dangerous-invisible U+<HEX>` line on stderr) and,
where applicable, `--write` sanitization.
Coverage:
Tag block (commit 1):
- U+E0041 TAG LATIN CAPITAL LETTER A — the range's printable ASCII
shadow; this is the byte sequence demonstrated in published ASCII
smuggling proofs of concept.
- U+E007F CANCEL TAG — the range end.
Other invisibles (commit 2):
- U+180E MONGOLIAN VOWEL SEPARATOR
- U+115F HANGUL CHOSEONG FILLER
- U+1160 HANGUL JUNGSEONG FILLER
- U+2061 FUNCTION APPLICATION (range start)
- U+2064 INVISIBLE PLUS (range end)
- U+3164 HANGUL FILLER
Detection table is data-driven (one loop, one assertion per row) so
adding the next invisible to the denylist also gets a paired
regression test by simply appending to NEWLY_COVERED_RANGES.
Plus a `--write` integration test:
- writes a markdown file containing both Tag block (5 chars) and
U+180E, runs `--write`, asserts both removed and surrounding text
preserved character-for-character ('# Title\n\nBenigntext.\n').
- re-runs the validator without `--write` and asserts exit 0,
confirming the sanitizer's output is idempotent under the
extended denylist.
Test count: 5 → 14 in this file; full `yarn test` green; `yarn lint`
clean.
coderabbitai flagged: the two `catch` blocks in `readSessionCost`
silently swallowed every failure mode. A malformed `costs.jsonl`
row, a permission error opening the file, or any other unexpected
I/O failure would silently return zero cost — masking real
problems and feeding stale or zero numbers into
`ecc-context-monitor.js` (which then injects them as
`additionalContext` into the live model turn).
Fix two things, both fail-open-preserving:
1. **Inner JSON.parse catch** — count malformed lines and write
one aggregated breadcrumb per call:
[ecc-metrics-bridge] skipped N malformed line(s) in <path>
Aggregating (rather than per-line) keeps a log-flooded
`costs.jsonl` diagnosable without overwhelming stderr.
2. **Outer fs.readFileSync catch** — write a breadcrumb on real
errors, but stay silent on `ENOENT`. The "no costs.jsonl yet"
case is genuinely normal (no Stop event has fired this session)
and producing noise on every PreToolUse before the first Stop
would be reviewer-visible spam. All other error codes
(`EACCES`, `EISDIR`, `EMFILE`, …) get:
[ecc-metrics-bridge] failing open after <name> reading <path>: <msg>
In both cases the function still returns the zero-cost fallback
so the bridge never breaks tool execution — only the
diagnosability changes.
Two new regression tests in
`tests/hooks/ecc-metrics-bridge.test.js`:
✓ readSessionCost writes a stderr breadcrumb when malformed
lines are skipped — feeds 4 rows (2 valid, 2 malformed),
asserts the last valid row still wins AND captured stderr
contains "skipped 2 malformed line(s)".
✓ readSessionCost stays silent when costs.jsonl does not exist
(ENOENT) — uses a fresh tmp HOME with no metrics dir, asserts
zero return AND empty stderr.
Test count: 16 → 18; `npm test` green; `yarn lint` clean.
`readSessionCost` read only the trailing 8 KiB of
`~/.claude/metrics/costs.jsonl` to "avoid scanning entire file".
That ceiling is the opposite-sign sibling of the double-count bug
fixed in the previous commit: once a session's most recent
cumulative row gets pushed past the 8 KiB window by newer rows
from other sessions, the bridge silently reports `totalCost: 0`,
`totalIn: 0`, `totalOut: 0` for that session — same false signal
to `ecc-context-monitor.js`, same wrong number injected into the
live model turn as `additionalContext`.
`cost-tracker.js` has no rotation policy, so on any non-trivial
workstation costs.jsonl grows past 8 KiB within minutes of normal
use. For users who keep multiple concurrent sessions, this means
the second-and-later sessions silently report zero almost
immediately.
Reproduced before this commit:
$ HOME=/tmp/eccc node -e '
const fs = require("fs");
const m = require("./scripts/hooks/ecc-metrics-bridge.js");
// S1 row at file start, then 200 rows of OTHER-session noise (~16 KiB).
// S1 is the row we want, but it sits past the 8 KiB tail.
const s1 = `{"session_id":"S1","estimated_cost_usd":0.5,"input_tokens":500,"output_tokens":250}`;
const other = `{"session_id":"OTHER","estimated_cost_usd":1,"input_tokens":100,"output_tokens":50}`;
fs.mkdirSync("/tmp/eccc/.claude/metrics", { recursive: true });
fs.writeFileSync("/tmp/eccc/.claude/metrics/costs.jsonl",
[s1, ...Array(200).fill(other)].join("\\n") + "\\n");
console.log(JSON.stringify(m.readSessionCost("S1")));'
{"totalCost":0,"totalIn":0,"totalOut":0}
Expected: `{"totalCost":0.5, "totalIn":500, "totalOut":250}` (the
S1 row that exists in the file).
Actual: zero — the row is past the 8 KiB tail.
Fix: drop the `fs.openSync` + bounded `fs.readSync` + position
arithmetic in favour of `fs.readFileSync(costsPath, 'utf8')` and
iterate every line. Each row is ~150 bytes; even 100k rows is
~15 MB and a single sync read on PreToolUse is in the low ms.
If file rotation lands in `cost-tracker.js` later, this scan
becomes proportionally cheaper.
After this commit the reproduction above returns
`{"totalCost":0.5, "totalIn":500, "totalOut":250}`.
Regression test in `tests/hooks/ecc-metrics-bridge.test.js`:
`readSessionCost finds session row beyond the old 8 KiB tail
boundary`. The test asserts the costs.jsonl fixture is > 8 KiB
before reading so any reintroduction of a bounded tail would
re-fail the test (i.e. the assertion is the contract, not the
specific number 8192).
Together with the previous commit, both directions of the
metrics-bridge cost-reporting bug are closed.
`ecc-metrics-bridge.js#readSessionCost` summed the
`estimated_cost_usd`, `input_tokens`, and `output_tokens` of
every matching row in `~/.claude/metrics/costs.jsonl`. That breaks
the documented contract of `scripts/hooks/cost-tracker.js`, which
explicitly states (in its module docblock):
Cumulative behavior: Stop fires per assistant response, not
per session. Each row therefore represents the cumulative
session total up to that point. To get per-session cost, take
the last row per session_id.
Summing N cumulative rows over-counts by roughly (N+1)/2 ×. For a
session with 3 rows at 0.01, 0.02, 0.03 USD (true running total
0.03), the bridge today reports 0.06 USD. The over-counted value
feeds `ecc-context-monitor.js`, which then trips its
COST_NOTICE_USD / COST_WARNING_USD / COST_CRITICAL_USD thresholds
on phantom spend AND injects the inflated number as
`additionalContext` into the live model turn — so the agent
itself is told a wrong cost.
Reproduced on `main` before this commit:
$ cat > /tmp/eccc/.claude/metrics/costs.jsonl <<EOF
{"session_id":"S1","estimated_cost_usd":0.01,"input_tokens":333,"output_tokens":166}
{"session_id":"S1","estimated_cost_usd":0.02,"input_tokens":666,"output_tokens":333}
{"session_id":"S1","estimated_cost_usd":0.03,"input_tokens":1000,"output_tokens":500}
EOF
$ HOME=/tmp/eccc node -e 'const m = require("./scripts/hooks/ecc-metrics-bridge.js"); \
console.log(JSON.stringify(m.readSessionCost("S1")))'
{"totalCost":0.06,"totalIn":1999,"totalOut":999}
Expected: `{"totalCost":0.03,"totalIn":1000,"totalOut":500}` (the
last cumulative row).
Actual: 2× over-count.
Fix: replace `+=` with `=` in the matching branch so the assigned
values reflect the most recent row encountered. The iteration
order is file order, which is also event time order, so the last
assignment wins — exactly the contract cost-tracker writes
against.
After this commit the reproduction above returns
`{"totalCost":0.03,"totalIn":1000,"totalOut":500}`.
Regression test in `tests/hooks/ecc-metrics-bridge.test.js`:
`readSessionCost returns the LAST cumulative row, not the sum
(cost-tracker contract)`. The existing
`readSessionCost does not include unrelated default-session rows`
test happened to pass even with the bug because it only had one
target-session row — single-row sessions are coincidentally
correct under both formulas. The new test uses three rows so the
two formulas diverge.
A second issue in the same function — the 8 KiB tail-only read
silently drops older rows once a session's recent cumulative
totals scroll past that window — is fixed in the next commit.
Three test changes in response to the round-1 review:
1. **Add quoted-write-all coverage** (cubic P0 follow-up).
Two new cases assert the regex now matches the double-quoted and
single-quoted YAML forms of `permissions: "write-all"`:
- `rejects double-quoted permissions: "write-all"`
- `rejects single-quoted permissions: 'write-all'`
Both fixtures trigger only the persist-credentials gate, so they
exercise the WRITE_ALL_PATTERN OR-clause in isolation.
2. **Add expression+ref dedup coverage** (greptile P2 follow-up).
`emits a single violation when both expressionPattern and refPattern
match the same step` — uses `refs/pull/${{ … head.sha }}/merge` as
the fixture (which matches both patterns) and counts ERROR lines for
the `pull_request_target` rule, asserting exactly one. Re-introducing
the duplicate-push bug would re-fail this test immediately.
3. **Drop the `npm ci without --ignore-scripts under write-all` test**
(greptile P2). That test happened to pass under the previous
`--ignore-scripts` regex, but `UNSAFE_INSTALL_PATTERNS` (added in
`f7035b56`) fires unconditionally for every workflow regardless of
permissions. So the test was exercising a pre-existing code path
that has nothing to do with WRITE_ALL_PATTERN. Reviewer flagged this
could mislead future contributors into thinking lifecycle-script
enforcement is gated on write permissions.
Replaced by the surrounding `rejects checkout credential persistence
in workflows with permissions: write-all` test (already present) and
the new quoted-form tests above, which all exercise the actual
persist-credentials gate that the WRITE_ALL_PATTERN clause newly
activates.
Test count: 22 → 24 (added 3 new, dropped 1). All green; `yarn lint`
clean.
The cohort comment above the write-all block was also tightened to
explicitly note that "the lifecycle-script gate already fires
unconditionally for every workflow" so the next reader sees the
distinction up front.
