Greptile P1: sedScriptParts stopped at -- and discarded the remaining
operands, so 'sed -- <script>' skipped script collection entirely. GNU sed
4.9 (verified): with no -e/--expression anywhere, the first operand after --
is the script and an s///e in it still executes.
The operands after -- are now collected as positionals, so the existing
first-positional-becomes-script rule applies. Operands after the script stay
file names (data). 2 regression tests pin both sides. Suite: 812/812.
Greptile P1 findings (both verified by running GNU sed against the hook):
1. Escaped replacements evade the check: GNU sed decodes \xHH, \oOOO, \dNNN,
case operations and unknown escapes like \g before executing an s///e
replacement or e operand. Scanning the raw text let \x67it decode to git.
Decoding that surface faithfully is out of scope, so any backslash in an
exec-bearing fragment now throws UnsupportedSedEscape and the hook blocks
with an explicit reason — mirroring the existing env -S escape precedent
instead of pretending to interpret sed. Escaped-newline continuations of an
e operand are refused by the same check.
2. Continued commands went unchecked: the e operand reader stopped at every
newline, but GNU sed joins escaped newlines into one operand. Now covered
by the same conservative refusal.
Also decomposes the sed readers into sub-50-line helpers per the repository
function-size rule (AGENTS.md): readSedDelimited, readSedCommand,
readSedExecute, readSedLineOperand, assertSedLiteral.
5 regression tests pin the escape paths and the benign boundary (a backslash
in a non-executing script stays data). Suite: 810/810.
CodeRabbit security review (Major, CWE-693) correctly identified that GNU sed
collects -e/--expression scripts from any argv position: a script option after
positional operands is still executed, so stopping the option walk at the first
positional let an e-flagged script hide behind it.
Verified against GNU sed 4.9 before fixing:
- 'sed -e s/x/y/ - -e s/y/X/e' runs X (the later -e executes)
- with any script option present, every positional is a file operand
sedScriptParts now walks the full argv, collects scripts from all -e/
--expression positions, and only promotes the first positional to the script
when no script option was given. Unknown options after positionals still fall
back to the opaque default.
4 regression tests pin the reported bypass paths (suite: 805/805).
Ported from the #3051 discussion (test intent, not the old scanner):
- A confidently-parsed sed invocation whose script contains no execution
construct is a pure text transformation: the script operand and every file
operand are data. This removes the specific false positives where file names
or non-executing scripts merely containing 'git ...' were blocked.
- The GNU sed `e` command (bare or with operand) and the `s` command with the
`e` flag run text through the shell. Their literal fragments (the s
replacement, the e operand) and any piped/redirected source are scanned as
real shell source, closing the `printf x | sed 's/x/git commit --no-verify/e'`
gap reported on 2026-10-09.
- Anything the literal parser cannot confidently read (addresses it cannot
consume, -f script files, -i suffix ambiguity, unknown options, expansion
residue) falls back to today's opaque default. No behavior changes for
unmodeled launchers.
- shell-scan.js is untouched and remains the canonical scanner.
Tests: 14 focused cases ported from the #3051 litmus set; full hook suite
801/801.
Honor ECC_DRY_RUN=1 in install and repair arg parsing (previously only --dry-run flag worked, so ecc --dry-run install/repair silently performed real writes). Make writeInstallState atomic via writeFileAtomic (O_EXCL staging, fsync, cleanup on failure, atomic rename preserving previous state). Add writeInstallState failure/concurrency/symlink regression tests and disposable-home CLI dry-run regression tests for both global and subcommand forms.
Track illustrative scopes and retain their connectors so a contrastive
request or rejection for the current task ends the preceding example.
Preserve complete skill aliases, outer discussion guards, quoted task
qualifiers, and indirect citation protection for scored admission.
Invalidate older routing receipts and add resolver/launcher regressions
for request ordering, scope boundaries, aliases, and the reported P1.
Treat example-framing prefixes as indirect citations before checking
rejections, preserving genuine requests around illustrative instructions.
Keep e.g. together during clause splitting without rewriting e.g.js tokens.
Bump routing policy to v10 to invalidate v9 selections that loaded example
context. Cover resolver, launcher, instruction ordering, and receipt reuse.
Allow neutral imperative task preambles before an explicit skill request
without admitting final bare mentions, questions, or subject-led reports.
Keep rejection-list scoping intact and recognize must/ought questions.
Bump routing policy to v9 so an empty v8 receipt is reconsidered. Cover
resolver and launcher behavior and document the affected routing helpers.
Keep follow-up questions and reported instructions on the proposal path by
requiring recognized scopes and a direct request prefix for exact admission.
Preserve grouped rejections, personal negation, and genuine directives around
indirect discussion. Invalidate v7 receipts with routing policy v8.
Cover both Greptile reproductions and neighboring resolver/launcher cases,
including unlisted wording, nested reports, and grouped negative lists.
Limit negation to each independent directive after comma, and, or but.
Accept imperative requests with question punctuation while preserving true
questions, reported speech, and ordered rejections. Bump routing policy to
v7 so prior empty selections are reconsidered.
Add resolver and launcher regressions for the individual cases and their
combinations, including cached selections and actual context injection.
Validate env -S and --split-string escape syntax before shell scanning or
opaque fallback. Preserve literal single-quoted data and charge each
validation character against the shared input-proportional work budget.
Verified 787 focused cases and 290 real Git/config, harmless native env
and registered-routing controls. Keeps the prior paid-copy protection.

Carry forward bounded literal include/includeIf configuration capabilities
and env -S/--split-string words from PRs #2858 and #2897. Charge array
copy and expansion work before allocation to preserve the shared quota.
Verified 731 hook cases and 60 real Git/config and registered-route
controls. Dynamic remainder and original full source PRs remain held.

Resolve six conflicts:
- hooks/hooks.metadata.json: keep this branch's gateguard description and
fingerprint, add upstream's hookify-runtime entries.
- package.json: keep both gateguard-report.js and github-coordination.js.
- scripts/hooks/gateguard-fact-force.js, tests/hooks/gateguard-fact-force.test.js,
skills/gateguard/SKILL.md: upstream added a simpler session denial cap; this
branch already has the fuller one (cap threaded through
markCheckedAndCountDenial, malformed-value warning, miss and target notes),
so keep it. Upstream's taskset and su wrapper handling, fail-closed
recursion limit and soft-hyphen sanitising merged cleanly and their tests pass.
- manifests/context-packs/skill-triggers@1.json: take upstream's file and
recompute registryDigest for the merged registry.
Treat non-2xx activity responses as feed errors, preserve non-Markdown Copilot agent assets, and apply the reviewed reference escape parity correction with regenerated bindings. Allow the test runner to drain piped output on its existing success or failure exit status. Validate installed workflows and bounded real Node20/24 pipe regressions.
Match the Windows missing volume-serial exception while retaining strict reported-device, inode, ownership, permission, link and snapshot checks. Add loader warning/block and race regression controls with isolated platform metadata injection.
The entries file was written in place with writeExclusive. A build that
stopped mid-write left partial bytes under the digest name, and every
later build refused them ("content changed under its digest"), so the
SessionStart builder could never restore the index.
Write it through the store's atomicJson (temporary file, then rename), so
a digest-named file only ever holds complete bytes, and replace an
existing file whose bytes do not hash to its name instead of trusting it.
Open with supported no-follow and nonblocking flags before relying on file metadata. Validate descriptor, pathname and rule-directory consistency before and after reading at most64KiB plus one overflow byte. Reject observed replacement, mutation, premature EOF and non-regular files, and close descriptors on every outcome.
Add12 race and I/O regressions. Keep the Hermes uppercase protected-file fixture real on case-sensitive filesystems and verify that the installed guard still permits first-time creation.
Validation: full6688 reported tests across347 files,12 race tests, full80% coverage gates, scoped Hookify coverage, installed Hookify and Hermes workflows, packed artifact lifecycle, lint, signatures and IOC.
- Call patterns now skip a require/import preceded by a dot, with or
without whitespace or optional chaining, so records.require('./label')
and obj?.import('./x') are method calls rather than module loads.
- Replace the one-level dynamic-argument pattern with a balanced-paren
scan over the string-free skeleton, so require(path.join(__dirname,
getName())) and require(a(b(c()))) are reported as dynamic.
Rescanning all 802 repository JavaScript files against the previous head
changes 6 results, each a newly reported dynamic argument nested deeper
than one level (docker eval checks and one test); no specifier or package
result changes. The real registry is unchanged: 35/35 resolved, zero
failures or warnings.
- An extensionless require now tries only the path, .js, .json, and a
directory's index.js/index.json, as Node does; .cjs and .mjs must be
named, so require('./helper') no longer passes on helper.cjs alone.
- Treat `}` as a statement boundary, so a regex after a block is read as
a regex and cannot swallow a later require.
- Decide whether a paren opens a condition from the token before the
keyword, ignoring whitespace, so `obj.\nif(x) / 2` and
`obj?. while(x) / 2` stay method calls followed by division.
- Record which slots came from template literals and skip them for
static `from` and side-effect `import`, which accept only a quoted
string; a tagged template named `from` is no longer an import.
A template passed to import() is still a dependency.
Rescanning all 802 repository JavaScript files against dd14493e changes
no result, and the real registry still reports 35/35 resolved with zero
failures or warnings.
Follow up PR #3187 at 38b8c07f while preserving the original contribution history and all current-main helper bodies. Remove both CI safety-suite exclusions, clean stale imports and the warning glyph, retain shipped test/coverage entrypoints, and keep unknown test totals honest. The tree matches the fully tested 6246-pass/325-file tree; disposable Claude/OpenCode lifecycle passes.
- Track whether each relative specifier arrives through require or
through import()/static import, and resolve the import forms by exact
path. Node's ESM resolver adds no extension and rejects directory
imports even from a CommonJS file, so import('./helper') and
import('./data') no longer pass on helper.js or data/index.json alone.
require keeps the CommonJS extension and index candidates.
- Stop normalizing backslashes in relative specifiers. Linux and macOS
read them as filename characters, so require('./lib\helper.js') now
fails as non-portable-separator instead of resolving to lib/helper.js.
- Record whether each closing paren ends an if/while/for/with condition,
so a `/` right after one starts a regex. A method named `if` and calls
nested inside a condition still read as division.
extractReferences gains an `imports` list. Rescanning all 802 repository
JavaScript files against the previous scanner changes no result, and the
real registry still reports 35/35 resolved with zero failures.
