…othing Five defects, none of them cosmetic. Refs wave-av/claude-workstation#1747. 1. FAIL-OPEN DIFF BASE. `BASE=$(git rev-parse HEAD~1 2>/dev/null || git rev-parse HEAD)` — on a root commit `git rev-parse HEAD~1` prints its unresolved argument to stdout AND fails, so the `||` branch appends and BASE becomes a two-line string. `git diff` then exits 128, and the pinned enforcer turned that into zero files and a green check. Now: a reachability-checked base (a force-push can leave `github.event.before` pointing at a commit this checkout does not have), and with no resolvable base at all it diffs against the EMPTY TREE so the whole repo is scanned rather than nothing. 2. THE PINNED ENFORCER ITSELF FAILED OPEN. `^0.4.4` resolved to 0.4.4, whose file lister is `catch { return []; }` — any git error became zero files and rendered as `OK[enforce]: 0 changed file(s) scanned — 0 A_BLOCK violations`. A git error and a clean diff were byte-identical in the output. The fix had sat unreleased on claude-workstation main since 2026-07-29 because no `governance-v*` tag was ever pushed. Released now as 0.4.6 and pinned exactly here. 3. TOKEN IN SCOPE FOR THE WRONG STEPS. `NODE_AUTH_TOKEN` was job-level, so it was also in the environment of the step that executes the downloaded package. Now step-scoped, and the .npmrc holding it is removed on exit. 4. INSTALL SCRIPTS RAN WITH THAT TOKEN. `npm install` runs preinstall/postinstall by default. Added `--ignore-scripts`. 5. CANCELLED PUSH RUNS WERE SCANNED BY NOBODY. `cancel-in-progress: true` applied to push runs, and each push run only diffs its own before..HEAD range — so a cancelled run's commits were never examined by anything. Now PR-only. Also: `timeout-minutes: 10` and `set -euo pipefail`. Receipt, against a scratch repo whose root commit carries a no-hardcoded-paths violation, simulating a branch-creation push (`before` = all zeros): old logic -> malformed base -> caught error -> [] -> OK, 0 files scanned, PASS new logic -> "no diff base resolved ... scanning the whole tree" -> BLOCK, exit 1 Credit where it is due: several of these were found by the review bots on the sibling vendoring PRs and are folded in here — the step-scoped token, the .npmrc cleanup, the exact pin, `--ignore-scripts`, the force-push reachability check, `timeout-minutes`, and the concurrency hole (5), which was crest-console#7's catch and which I had missed entirely.

🔍 Pinned version differs from PR description; verify 0.4.6 accepts a tree object as --changed base
The workflow pins @wave-av/governance@0.4.6 while the PR description states ^0.4.4 — the inline FIX 3 comment explains the change, so this is intentional drift in the description, not the code. The one thing worth verifying externally: the fail-closed path passes the empty tree hash (git hash-object -t tree /dev/null) as the --changed base. That works with a two-dot git diff <tree> <commit>, but if enforce.mjs internally uses three-dot (BASE...HEAD) or git merge-base, a tree object is rejected and the step would error. Since this path is the deliberate fail-closed branch, an error is loud rather than silently green, but it would produce a confusing failure rather than a whole-tree scan. Worth confirming against the 0.4.6 implementation.

Verified against the 0.4.6 source: both enforce.mjs and enforce-ramp.mjs build the diff via changedArgs(), which uses the two-argument form git diff <base> HEAD (explicitly documented as accepting trees, chosen precisely because A...B rejects the empty-tree object this fallback supplies). The empty-tree base yields a genuine whole-tree scan, so no change is needed.

…l a false pass Correction to the previous commit on this branch. Refs wave-av/claude-workstation#1747. That commit replaced the fail-open `BASE=HEAD` with a fallback to `HEAD~1`. `HEAD~1` is also wrong: it scans exactly ONE commit, so a five-commit push whose base is indeterminate (branch creation, force-push, unreachable `github.event.before`) examines the last commit and reports a confident pass on the other four. A narrowed scan reported as a full pass is the same defect in a quieter costume. Receipt — scratch repo, five-commit push, violation planted in commit 1: HEAD~1 base -> OK[enforce]: 1 changed file(s) scanned -> PASS (never saw it) empty-tree base -> 5 changed file(s) scanned -> BLOCK[enforce]: no-hardcoded-paths, exit 1 Now: with no resolvable base of any kind, diff against git's empty-tree object so every tracked file reads as added and the whole repo is scanned. Loud, never partial, never empty. Credit: wave-av/wave-rig's copy on main already had this right, with the reasoning in a comment ("HEAD~1 would skip earlier commits in a multi-commit push and let a violation through"). The fan-out copied the broken shape from elsewhere and I did not check the one repo that had already solved it. Also from wave-rig: `merge_group` is now a declared trigger and `github.event.merge_group. base_sha` joins the base chain. None of these repos runs a merge queue today, so the trigger is inert — but a required check that never reports on an event the repo actually uses is a permanent deadlock, and this closes that in advance rather than after someone hits it.

Adds the
governance-enforceA_BLOCK gate (secrets / hardcoded-paths, diff-scoped) to this repo. Part of claude-workstation#1624 E4 T4.9a, following thewave-av/cli#20pilot.Why this repo had no secrets scan
The org ruleset
governance-a-block-enforce(17901847) requires anenforcecheck across the fleet. Its scope is an explicit include list of 112 hand-maintained repository names — and every one of them matcheswave-*.The 16 public repos absent from that list are exactly the 16 not named
wave-*:.github,adk,api-spec,cli,companion-module-wave,create-wave-app,crest-console,dispatch-edge,examples,mcp-server,obs-wave-plugin,sdk,sdk-python,sdks,vmix-wave-integration,workflow-sdk.Read the intersection: the repos that publish our npm packages are precisely the repos running with no A_BLOCK secrets scan. Nobody excluded them. A naming convention silently became a security boundary, and it drew the line in the worst possible place.
Why the workflow lands before the ruleset entry
Adding a repo to a
required_status_checksruleset before it emits that check is a permanent deadlock — a required check that never reports can never go green, and every PR on the repo becomes unmergeable. So the order is: vendor the workflow, observe it green, then extend the list. Doing it the intuitive way round would have bricked all sixteen.This PR is also its own liveness drill. The workflow triggers on
pull_request, so it runs on the PR that adds it. Ifenforcereports green here, the vendored shape works in this repo. If it does not, nothing was required and nothing is blocked — which is the point of this ordering.Proven before fan-out, not assumed
@wave-av/governanceis aninternal-visibility package owned byclaude-workstation, so whether a public repo'sGITHUB_TOKENcan read it was the one real assumption. Rather than fan out on the inference, it was piloted on a single repo first:That is the receipt this PR rides on. The shape is copied verbatim from
wave-av/wave-moq-edge(public, 12/12 green), which matters becauseauto-approve.ymlfails silently on every public repo — it calls a reusable workflow in the privatewave-foundation, and a public repo cannot do that (parse-time failure, zero jobs, no annotation). This workflow calls nothing cross-repo, so that trap does not apply.Security properties, unchanged from the source:
actions/checkout@df4cb1c,actions/setup-node@48b55a0)persist-credentials: falseon checkoutcontents: read+packages: readRUNNER_TEMP,--no-save, so nothing touches this repo's dependency tree.npmrcis written with a literal${NODE_AUTH_TOKEN}(single-quotedprintf) which npm expands at run time — no secret value is ever written to disk or a log${{ }}inputs (base.sha,event.before) are routed throughenv:and read as"$VAR", never interpolated into the script bodyDiff-scoped by design: it blocks new violations without failing on legacy debt.

Overview
Adds
.github/workflows/governance-enforce.yml, bringing this repo under the same diff-scoped A_BLOCK gate (secrets in git, Doppler sourcing, hardcoded paths) that org rulesetgovernance-a-block-enforceexpects via anenforcejob check.The workflow runs on PRs and pushes to
main/master: full-history checkout, isolated install of@wave-av/governance@0.4.6with--ignore-scripts, thenenforce.mjs --changed <base>. Hardening baked into the vendored copy includes step-scoped registry token, push concurrency that does not cancel in-progress (so push diffs are not skipped), validation of the diff base with fail-closed fallback to the empty tree when no base resolves (instead of a no-opHEADdiff).The workflow is intentionally landed before adding this repo to the ruleset so a required check that never reports cannot deadlock merges.

Note
Add governance enforcement workflow to scan diffs on PRs and pushes to main
Adds governance-enforce.yml, which runs
@wave-av/governance@0.4.6on pull requests, merge groups, and pushes to main/master. The enforcer scans only changed files using a computed diff base; if no valid base is found, it falls back to the empty tree and scans the full repository. Push and merge group runs are not cancelable to ensure no committed ranges are skipped.Macroscope summarized 4b9480e.
