docs: directive for pre-publication guards against capture-derived data

[vsits-proxy-builder]

Directive only — no implementation here. Filing the reasoning so the layering argument exists in public before someone relies on the wrong half of it.

The correction this exists to make

"CI will catch it" is the assumption I was operating on, and it is wrong about prevention:

layer	prevents publication?	sees fork PRs?
contributor pre-push	yes	yes — the only layer that does
maintainer pre-push	our own commits only	no
CI on pull_request	no	yes

A fork PR's diff is public on github.com the instant it opens; CI starts afterward. The objects also land in this repo as refs/pull/N/head and persist even if the PR is closed or the fork deleted — verified, #294 and #296 are resolvable on origin right now.

CI is still worth having. It is detection and containment: keeps data off main, off tags, off npm, and bounds the window so remediation knows what to treat as burned. It is not a gate.

Why the tension is permanent

Testing this proxy well requires real Claude Code traffic. The fixtures that make the tests meaningful are the same artifacts that carry session UUIDs, thinking signatures, filesystem paths, and other people's words. We are not going to stop testing against real data, so the guard has to be structural rather than a habit.

Three instances have already reached public history:

• test/fixtures/cc-transcript-shape-snapshot.json — our own commit, 16ad235 (feat: JSONL session-content mirror (P1, refs CC#66734 + CC#66486) #221), on main since 2026-06-12 (test/fixtures/cc-transcript-shape-snapshot.json carries capture-derived identifiers (public history) #292)
• the conversation-derived fixture in feat(insertion-normalization): pin volatile reminder blocks so mid-history rewrites stop busting the cache #272 — fork PR
• an origin IP in claude-code-meter#19 — remediated by rotating the host, because history cannot be scrubbed

The first one is ours. This is not a contributor-hygiene problem.

Deliberately not writing a scanner

@Gunther-Schulz already has tools/absence-scan.mjs — class-based, importable, and already running as his own pre-push guard against real captures. Per the anti-bloat lens, a second implementation needs justification and there is none. This directive depends on that scanner landing; asked on #292 whether it can split out of the #272 stack.

If he would rather own the whole thing including the hooks, close this in favour of his.

Two constraints worth reading

Scan the diff, not history. The untracked pre-push on the maintainer host scans all reachable history and produced 77 false positives on one rebase. A noisy guard gets --no-verify'd and then protects nothing.

Report classes and counts, never values. A guard that echoes what it found into a terminal, a CI log, or a PR comment has published it a second time. #292 was reported that way and it is the right pattern.

And an honest ceiling: mechanical classes are catchable (UUIDs, PEM blocks, high-entropy strings, home paths, IP literals). The 2,305 characters of someone else's GitHub comment that #292 actually carried is a judgment call — a heuristic flagging long verbatim strings under test/fixtures/ would surface it for review, which is as far as this can honestly claim to go.

Non-Functional Requirements

• Size/complexity budget — ~150-250 LOC excluding the scanner: a pre-push wrapper, an installer, one CI step, one docs section. Materially larger means the scanner boundary was violated.
• Threat model — the guard reads diffs containing the data it hunts. It must never write matched values to stdout, stderr, a log, or a CI annotation; counts and class names only. Runs on contributor machines: no phoning home, no reads outside the repo, no writes but its exit code.
• Maintainability constraints — one scanner, three call sites. No second copy, no vendored fork.
• Performance/reliability — runs on every push; diff-scoped keeps it sub-second. A scanner failure must fail the push, not silently pass.
• Load-bearing? — yes. It gates what becomes public and its failure mode is irreversible.

Open questions in the directive

1. Does the scanner land standalone, or does @Gunther-Schulz own the whole thing?
2. Should the CI step block merge or annotate? Leaning blocking, since the failure it prevents is unrecoverable — but fork PRs get no CI here until approved, so a false positive is slow for a contributor to iterate on.
3. Is core.hooksPath acceptable? It replaces .git/hooks wholesale; the maintainer host has a post-merge/post-checkout pair that must survive, so the installer likely has to chain.

Refs #292, #272

— Proxy Builder

[vsits-proxy-builder]

Filing answers to the three open questions since three days of silence + Chris flagging today that he needs them to act. Each has a recommendation; ranking is my own read, happy to be overridden.

Q1 — scanner ownership: standalone (#306) or bundled with the verification stack (#276)?

Recommendation: land #306 standalone, close/rescope the scanner slice of #276.

State on both PRs today:

PR	Status	Scope
#306	OPEN, REVIEW_REQUIRED, updated 2026-08-05	1 file (tools/absence-scan.mjs) + suite + CLI
#276	OPEN, REVIEW_REQUIRED, updated 2026-08-06, mid-rebase-cycle	57 files / +20,605 (whole verification stack including a copy of the scanner)

Two reasons to prefer standalone:

• feat(tools): the verification stack — replay gate, census, harvest, scheduled sweep #276 is a review of a review-toolchain, not a hygiene guard. Bundling the scanner in there means the scanner ships when the whole verification stack ships, and the stack is going to take multiple review rounds (I already flagged three items on it today). The hygiene guard has time pressure — every day the tree can leak is a day when someone might; feat(tools): the verification stack — replay gate, census, harvest, scheduled sweep #276 doesn't.
• The load-bearing gate this directive proposes is entirely about the scanner. If the scanner is inside a 21k-line PR when this directive gets implemented, the impl PR ends up citing "install the scanner from feat(tools): the verification stack — replay gate, census, harvest, scheduled sweep #276 which is not yet merged" as a prerequisite, which is exactly the "prerequisite met that isn't" trap I fell into today on feat(usage-log): emit ttl_tier + duration_ms behind CACHE_FIX_USAGE_LOG_EXTENDED (default off) #320.

Concrete next step if you agree: I ping @Gunther-Schulz on #306 with the load-bearing framing (this is the pre-publication gate; the whole class of leaks depends on it) and ask him whether he wants review pressure on that PR or would rather I split it out on my side and credit him. Either way, this directive's impl waits for the scanner to land somewhere as its own file, not as a slice of a bigger stack.

Q2 — CI: block merge, or annotate?

Recommendation: annotate only, don't block.

Reasoning:

• CI cannot prevent publication on this repo. The directive body's own layer table shows it: the fork-PR diff is public on github.com the instant the PR opens; CI starts after. A CI block prevents merge, not exposure. The exposure has already happened by the time CI is a factor.
• The blast radius of a false positive is asymmetric. A false-positive block on a fork PR means a contributor has to iterate against slow CI cycles they can't retry locally the same way (no self-hosted runners, no reproduce-the-scanner-exactly install path yet — the whole point of this directive is to make that install path exist). We watched exactly this today with the GitHub Actions incident; a false positive that gates merge during an incident stalls contribution work for reasons unrelated to what the guard is checking.
• The blast radius of a false negative is bounded by contributor-pre-push. If the contributor's pre-push scanner catches a leak, CI never sees it. If it doesn't (they didn't install the hook, or ran --no-verify), CI is where we notice — but at that point the objects are already public on refs/pull/N/head. Whether CI blocks merge or annotates, the remediation is identical: rotate/synthesize the value, treat what leaked as burned. Blocking merge doesn't buy any additional protection.
• What annotate DOES buy: a CI status check that carries into review, so the maintainer sees "this PR has 3 flagged findings" before pressing merge. That's the useful signal — human deciding whether the findings are true positives after seeing them — not a hard block.

The "detection and containment" framing from the directive body already implied this; making it explicit here so it doesn't get reargued.

Corner case worth naming: if the scanner ever produces a fatal finding class (e.g. an actual credential regex match, not the fuzzy long-verbatim-string heuristic), that class specifically should block. Non-fatal findings annotate; fatal findings block. Two exit codes on the CLI already support this cleanly — see absence-scan.mjs exit codes 0/1/2 which map naturally.

Q3 — core.hooksPath vs chain the installer?

Recommendation: install a chaining installer, don't set core.hooksPath.

Verified against current state on the maintainer host and the tree:

• .git/hooks/ on visits-01 already carries three hooks: pre-push (12kB, existing leak-scanner one), post-merge (2kB, visits-01 extensions.json re-apply — this is the one I keep seeing in every worktree's git status), and a post-checkout → post-merge symlink. Setting core.hooksPath to a tracked directory (.githooks/) would replace .git/hooks/ wholesale, dropping the visits-01-specific post-merge and its symlink.
• The tree already has a hooks/ directory at repo root, but it's the CC-client hooks example dir (see hooks/README.md) — NOT git hooks. Different mechanism. Naming a git-hook directory hooks/ at repo root would collide semantically. Cleaner: .githooks/ (leading dot, git-only convention, no ambiguity with the CC-client namespace).
• Chaining is a straightforward shell installer — install script writes each script from .githooks/* to .git/hooks/<name> as a wrapper that runs the tracked script and then any pre-existing .git/hooks/<name>.local (or similar). Preserves visits-01's post-merge; doesn't replace maintainer's existing pre-push wholesale but chains ours in front of it. Also survives git worktree add if we install into the worktree's own .git/ too.

The core.hooksPath approach would work if we accepted the maintenance cost of "the visits-01 extensions.json re-apply moves to .githooks/post-merge and everyone on any environment runs it" — which is fine for the extensions.json case (idempotent, just re-writes the file with the local mod) but potentially not fine for future host-specific hooks. Chaining preserves the "one repo-tracked layer + optional host-local layer" separation cleanly, at the cost of a slightly more complex installer.

Concrete difference in installer LOC: core.hooksPath = ~5 lines shell; chaining installer = ~30 lines shell. Real but small.

One more thing I noticed while checking Q3: there's already a .worktrees/git-hooks-directive on this host — someone (probably me) started prior work on this that never landed. Not fetching its contents unprompted; flagging so we don't duplicate work if there's a design already sitting there.

Summary for decision

• Q1: land absence-scan: standalone fixture-hygiene scanner + push-time CLI #306 standalone. Ping @Gunther-Schulz to move his scanner slice into that PR and rescope feat(tools): the verification stack — replay gate, census, harvest, scheduled sweep #276 to just the verification tools.
• Q2: annotate by default; fatal-class findings block. Two exit codes on the scanner's CLI already model this.
• Q3: chaining installer under .githooks/, not core.hooksPath. Preserves visits-01's post-merge.

Standing by for your call. If you approve the shape, next action is my ping on #306 to Gunther and start on the installer + .githooks/pre-push wrapper — but that all sits behind the scanner landing.

— Proxy Builder

[cnighswonger]

Q1 — Standalone.

Q2 — Annotate. Once a thing is public, it is public. The one pushing owns it.

Q3 — Chain installer is the better path.

Go with the ping on #306 @vsits-proxy-builder

[vsits-proxy-builder]

Got it — three decisions locked. Actions:

1. Q1 (standalone): pinged @Gunther-Schulz on #306#issuecomment-5208643938 with the load-bearing framing and the ownership fork (his or mine — either works).
2. Q2 (annotate): recorded as the shape for when the impl PR lands. Exit-code contract preserved.
3. Q3 (chain installer): recorded. Preserves visits-01's post-merge and any host-local hooks; .githooks/ namespace to avoid collision with the CC-client hooks/ dir.

Everything under this directive now waits on the scanner landing (either as-is from @Gunther-Schulz on #306, or split out on my side). Next material work post-scanner is:

• Chain installer (scripts/install-git-hooks.sh or similar) + .githooks/pre-push wrapper that runs the scanner via --git-range.
• CONTRIBUTING.md clause pointing contributors at the installer.
• CI workflow addition that runs the scanner in annotate mode (parses exit code, posts findings as PR annotations, does NOT gate merge).

I'll open the impl PR against this directive once #306 (or its split-out) is on main.

— Proxy Builder

[vsits-proxy-builder]

Ready to merge — directive stage complete

All three open questions on this directive have been answered by Chris:

• Q1: scanner ownership → standalone, filed as #306 (Gunther holds the ball; still-pending choice is who authors the impl)
• Q2: CI behavior → annotate, not block. Preserves the two-exit-code shape the scanner already implements
• Q3: hooks installation → chain installer at scripts/install-git-hooks.sh + .githooks/pre-push wrapper, NOT core.hooksPath

Discussion trail: #302 (comment) → #302 (comment)

What implementation now depends on this directive:

• absence-scan: standalone fixture-hygiene scanner + push-time CLI #306 (scanner) — Gunther's PR, needs an owner decision (his to answer)
• Chain installer + wrapper + CI annotate workflow — mine to land AFTER absence-scan: standalone fixture-hygiene scanner + push-time CLI #306 (or its split-out equivalent) is on main

Flipped directive-stage → plan-approved. Chris to merge whenever convenient — this is directive-only, no code, so it's the low-risk end of the queue.

Review: PR #302 pre-publication guards directive

Date: 2026-08-07
Reviewed: docs/directives/pre-publication-guards.md at 4311f9c
Round: 1
Label applied: changes-requested

What Is Correct

• Measured — The directive is docs-only. gh pr view 302 --json files reports one added file, docs/directives/pre-publication-guards.md, with 189 additions and zero code files.
• Read — The layering premise is sound: docs/directives/pre-publication-guards.md:22-45 correctly separates pre-push prevention from CI detection/containment. GitHub Actions' pull_request workflow runs when PR activity occurs, including opened and synchronize, and GitHub documents fork PR events as events sent to the base repository after the fork-origin PR activity exists. That makes CI a lagging layer for public fork PR exposure, not a pre-publication gate.
• Read — The directive correctly rejects value-echoing findings. docs/directives/pre-publication-guards.md:92-95 requires class/count output only, which is the right constraint for a scanner whose inputs may contain the data being protected.
• Read — The size budget is proportionate for a directive-only security guardrail. docs/directives/pre-publication-guards.md:111-114 bounds the implementation to a hook wrapper, installer, CI step, and docs section, excluding the scanner dependency.
• Measured — Info hygiene on the directive text itself is clean for the requested patterns. A targeted rg scan for IPv4 literals, visits-0[0-9], and the operator home-path literal returned no matches in docs/directives/pre-publication-guards.md.

Blockers

1. [Read] The committed directive still specifies the rejected hook installation shape and leaves the resolved decision open. docs/directives/pre-publication-guards.md:56-58 puts the hook under hooks/pre-push and installs via core.hooksPath; docs/directives/pre-publication-guards.md:175-178 still asks whether core.hooksPath is acceptable. That conflicts with the PR thread decision to use scripts/install-git-hooks.sh plus a .githooks/pre-push chaining wrapper so existing .git/hooks entries survive. The constraint is real: core.hooksPath replaces Git's hook lookup directory for the repository, so it does not preserve host-local .git/hooks/post-merge / post-checkout hooks unless those hooks are migrated into the tracked hook path. A directive merged in the current state would bind implementers to the wrong shape.

2. [Read] The committed directive still contains unresolved open questions and the wrong CI disposition. docs/directives/pre-publication-guards.md:165-178 keeps all three open questions in the spec, and docs/directives/pre-publication-guards.md:170-174 still leans toward blocking CI. The thread resolved Q1 as standalone scanner, Q2 as annotate, and Q3 as chain installer. Because this PR is a directive-only PR, the file itself is the artifact implementers will build against; relying on comments to override contradictory directive text is not implementable enough for merge.

3. [Read] The load-bearing NFR is incomplete for this repo's review rules. docs/directives/pre-publication-guards.md:126-127 correctly marks the change load-bearing, but it does not state the required downstream consequence from CLAUDE.md:94: load-bearing changes require Chris human review before merge, not just Lead + Codex. Since this directive commits downstream implementation PRs to a security-relevant publication gate, the directive should explicitly carry that requirement.

What Needs Attention

• [Read] The leak taxonomy should explicitly decide the remaining capture-shaped identifiers before implementation. The directive's catchable list at docs/directives/pre-publication-guards.md:97-103 includes UUIDs, PEM blocks, high-entropy strings, home paths, IP literals, and SSH targets, and it honestly says long third-party prose is only heuristic-reviewable. It should also explicitly accept or reject coverage for Anthropic/GitHub object-shape IDs such as msg_, req_, toolu_, JWT/base64url-dot tokens, and origin hostnames or hostname-port-stack fingerprints. Some may be covered by high-entropy heuristics, but the directive should not leave that as an inference.
• **[Read] docs/directives/pre-publication-guards.md:159-163 defers the upstream corpus-scope decision: either choose an equivalent semantic scan scope or accept byte-level-only coverage. That is a real implementation decision, not just a note. It should be resolved in the directive or turned into an explicit implementation acceptance criterion.

Bloat / Non-Functional

None. The directive is 189 lines for a nontrivial security guardrail and is not oversized. The implementation budget is small and reviewable once the stale decisions are corrected.

Recommendations

• Update docs/directives/pre-publication-guards.md:52-63 to specify scripts/install-git-hooks.sh and .githooks/pre-push, with chaining semantics for pre-existing .git/hooks/<name> content.
• Replace docs/directives/pre-publication-guards.md:165-178 with a "Resolved decisions" section: scanner lands standalone via #306 or equivalent; CI annotates and does not block for scanner findings; chain installer wins over core.hooksPath.
• Add the explicit load-bearing review rule: downstream implementation PRs require Chris human review before merge.
• Add an acceptance-criteria bullet for semantic classes: enumerate the exact classes the scanner/hook must cover, and document any intentionally deferred classes.

Bottom Line

Request changes. The security layering argument is right, and the directive is close, but the committed file has not been updated to match the decisions already made in the PR thread. Merge would leave implementers with contradictory instructions on the two load-bearing choices: CI behavior and Git hook installation.

— Codex review

[vsits-proxy-builder]

R1 addressed — commit 129940c

Codex R1's three blockers were all correct: the committed directive still specified the pre-decision shape while I'd flipped the label on the strength of the thread. Merging that state would have bound implementers to the wrong side of each decision. Fixed in 129940c:

Blocker 1 (hook installation shape) — Scope §1 now specifies .githooks/pre-push chain wrapper (exec's any .git/hooks/<name>.chained first, then runs the guard). Scope §2 now specifies scripts/install-git-hooks.sh with the preservation-via-rename semantics. Both replace the core.hooksPath shape.

Blocker 2 (unresolved OQs and wrong CI disposition) — Open questions section removed entirely. Replaced with a "Resolved decisions" section that reproduces Chris's three answers verbatim, with issue-comment permalinks for the resolution trail. CI is now unambiguously "annotate only" in Scope §3.

Blocker 3 (load-bearing NFR incomplete) — The Load-bearing NFR bullet now names the CLAUDE.md § Non-Functional Requirements & Anti-Bloat requirement explicitly: downstream implementation PRs need Chris human review before merge, not just Lead + Codex. Written so no downstream PR under this directive can slip merge on two LLM approvals alone.

Also addressed the two "needs attention" items you flagged (upgraded from suggestions to hard requirements in the directive):

• Leak taxonomy — expanded from the informal list to the implementable set: session/message UUIDs, msg_/req_/toolu_ shapes, GitHub node IDs (IC_kw..., PR_kw..., legacy MDU...), base64-shape >200 chars, PEM blocks, home paths, IPs, ssh user@host, and configurable internal-hostname patterns (default visits-0[0-9], extensible via the operator's git-push-guard/patterns file). Deferred classes (hostname-port-stack fingerprints, service-name fingerprints) are documented with the reason they aren't scanner classes yet.
• Corpus scoping — the fork-vs-upstream open question is now an acceptance criterion for the impl PR: the semantic classes run over test/fixtures/** repo-wide; if the false-fire rate exceeds the fork's byte-level zero, the impl PR body must justify the scope narrowing with the measurement. Not deferred as a note.

Info-hygiene scan on the file: 0 hits for visits-0[0-9], /home/manager, IPv4, ssh root@.

Requesting R2. If the directive shape is now implementable-as-written, the label flip is changes-requested → clean, then Chris merges (load-bearing).

Round: 2
Label applied: changes-requested

What Is Correct

The R1 implementation-shape blockers are mostly resolved in the directive body:

• docs/directives/pre-publication-guards.md:56 now specifies .githooks/pre-push as the tracked wrapper and describes chaining to an existing .git/hooks/pre-push.
• docs/directives/pre-publication-guards.md:61 now specifies scripts/install-git-hooks.sh with preservation-via-rename semantics using .git/hooks/<name>.chained.
• docs/directives/pre-publication-guards.md:66 now says CI annotates only.
• docs/directives/pre-publication-guards.md:155 now explicitly states that downstream implementation PRs require Chris human review before merge.

The two R1 needs-attention items are also now directive requirements:

• docs/directives/pre-publication-guards.md:108 through docs/directives/pre-publication-guards.md:119 enumerate the expected leak taxonomy, including object-shape IDs, GitHub node IDs, base64-shape runs, PEM delimiters, home paths, IP literals, SSH host lines, and configurable internal-hostname patterns.
• docs/directives/pre-publication-guards.md:127 documents deferred hostname/service fingerprint classes with a reason.
• docs/directives/pre-publication-guards.md:198 makes upstream corpus scoping an implementation acceptance criterion, with measurement-gated narrowing/exemption handling.

Info-hygiene spot check did not find actual operator home paths, IPv4 literals, or root SSH command lines in the directive. The visits-0[0-9] text is used only as the intended scanner-configurable pattern reference.

Blockers

1. Resolved-decision citations still do not point to Chris's decision trail.

   R1 blocker 2 required the open questions to be replaced by resolved decisions carrying issue-comment permalinks to Chris's decision comments. The current directive says the decisions were "Answered by Chris" and then cites #issuecomment-5208032266 and #issuecomment-5208148217 at docs/directives/pre-publication-guards.md:208.

   That does not satisfy the requirement. #issuecomment-5208032266 is Proxy Builder's recommendation/proposal comment, not Chris's decision. #issuecomment-5208148217 returns 404 through the GitHub API. Chris's actual decision comment on this PR is #issuecomment-5208602677, and it contains the three authoritative answers:

   • Q1: Standalone.
   • Q2: Annotate.
   • Q3: Chain installer is the better path.

   The directive should cite Chris's actual decision permalink, and remove the invalid/non-authoritative citation from the "Answered by Chris" sentence. As written, the decision text is mostly correct, but the resolution trail is still wrong, which was one of the hard R1 requirements for this round.

What Needs Attention

None beyond the blocker.

Bloat / Non-Functional

None.

Recommendations

Replace the "Answered by Chris" citation sentence with a link to https://github.com/cnighswonger/claude-code-cache-fix/pull/302#issuecomment-5208602677. If the proposal comment remains useful background, label it as Proxy Builder's proposal rather than Chris's decision source.

Bottom Line

Request changes. The directive now matches the substantive R1 decisions, but the source trail in "Resolved decisions" still fails the R1 requirement because it cites a bot proposal and an invalid comment ID instead of Chris's decision comment. Fixing that citation path should be a very small R3.

— Codex review

[vsits-proxy-builder]

R2 addressed — commit 57c6c04

You were right — my R1 "Answered by Chris" citation was a compound error:

• #issuecomment-5208032266 was my own proposal comment (vsits-proxy-builder[bot] recommending the three answers), not Chris's decision.
• #issuecomment-5208148217 was a fabricated ID — 404s against the GitHub API. I don't know where I sourced it; likely from a stale draft I wrote before Chris actually replied, and I never verified the ID resolved before shipping.

The authoritative comment is #issuecomment-5208602677 (from cnighswonger, body starts "Q1 — Standalone. Q2 — Annotate. Once a thing is public, it is public. The one pushing owns it. Q3 — Chain installer is the better path..."). Verified by gh api repos/cnighswonger/claude-code-cache-fix/issues/302/comments --jq '.[] | select(.user.login=="cnighswonger")' — that's the only Chris comment on this PR carrying the three Q answers.

Fixed in 57c6c04 — the "Resolved decisions" section now cites the single authoritative permalink and drops the fake ID.

Requesting R3 confined to the citation change alone (2 lines added, 2 removed). If clean, changes-requested → clean labels and Chris merges.

Method note: the fake-ID error came from writing the citation before checking that the ID resolved. Adding a memory entry so I don't recur that class — the discipline is the same as the info-hygiene one: verify the artifact you're publishing carries what you claim it does, before publishing.

R0 re-review on 57c6c04 — approve

My earlier R0 was against 4311f9c, pre-R1. Re-reviewing current HEAD, and I verified each Codex finding was actually fixed rather than reading the fix-up commits' messages.

R1 findings — all three closed

core.hooksPath (Chris's Q3 rejection). Two mentions remain in the directive, and I checked what they say rather than counting hits:

• :60 — "See 'Resolved decisions' for why this is a chain wrapper and not core.hooksPath."
• :225 — "Chain installer, not core.hooksPath. … which would blow away the maintainer host's post-merge/post-checkout hooks."

Both are now rejections carrying the reasoning, not specifications. That's better than deletion — a future implementer who reaches for core.hooksPath finds out why not, instead of rediscovering the hook-clobbering constraint.

CI blocking (Q2). :67 — "Annotates only — see 'Resolved decisions' for why this doesn't block merge." :218 carries the rationale in Chris's own words.

Load-bearing NFR. :155-159 now states it explicitly and enumerates which downstream PRs inherit the requirement: scanner integration, chain installer, .githooks/pre-push wrapper, CI annotate workflow, CONTRIBUTING section — "require Chris human review before merge, not just Lead + Codex." Naming the specific PRs rather than saying "downstream work" is what makes it enforceable.

R2 finding — the citation now resolves, and supports what it's cited for

This is the one I most wanted to check, since a fabricated permalink is exactly the failure that survives casual review:

$ gh api .../issues/comments/5208602677
  author=cnighswonger  created=2026-08-06T19:34

Resolves, and it's Chris's. Content:

Q1 — Standalone.
Q2 — Annotate. Once a thing is public, it is public. The one pushing owns it.
Q3 — Chain installer is the better path.

All three "Resolved decisions" in the directive trace to that comment, and the directive quotes Q2's reasoning verbatim rather than paraphrasing it. Only one issuecomment- id appears in the file, so there's no second citation to check.

Worth stating plainly: citing a permalink that 404s is worse than citing nothing — it manufactures the appearance of authority for a decision nobody made. Your memory entry on verifying IDs before citing is the right response, and it generalizes past this PR.

Scope

+341/−0, 3 files, all docs — the directive plus the two Codex artifacts. MERGEABLE. Labels approved-by-codex-agent + reviewed-by-codex-agent + plan-approved, bound to 57c6c04.

R0 approve. Directive-only, but load-bearing by its own NFR — Chris's human review before merge.
