fix(scripts): give the desired-state digests a writer - #180
Conversation
validate-manifests.sh treats the content digests in a *.desired-state.json resource as a required gate, but nothing in this repository ever wrote them. A branch that legitimately changes a bundled agent, skill, or runtime asset — the daily agent-skills sync being the standing case — therefore produces a manifest its own CI rejects, and re-running the sync cannot fix it. Only a hand edit could, and a hand edit does not survive: on 2026-09-01 a digest fix pushed to deps/agent-skills-update was force-pushed away by the next sync run 6 minutes later, restoring the stale value with no signal that it had happened. Add scripts/refresh-desired-state-digests.sh as that writer and run it in the same follow-up job that already bumps plugin versions on the sync branch, so the generated branch is self-consistent by construction. The generator and the validator now source their two hashing rules from scripts/sha256.lib.sh rather than each carrying a copy: a generator that disagreed with the gate about what a file hashes to would leave the branch exactly as unmergeable as having no generator at all. Fixes #179

📝 WalkthroughWalkthroughThe change adds shared SHA-256 helpers and a script that refreshes digests in desired-state resources. The script supports write and check modes, validates inputs, handles normalized definition files and raw runtime assets, and fails on missing or unmapped sources. Self-tests cover fixture behavior, failure cases, and validator coupling. The updater workflow refreshes and commits changed digests before pushing. CI and Merge Risk: 🔵 Low · up to The PR automates digest updates and aligns generation with validation, but an interrupted refresh could leave partially updated or malformed metadata in a reused workspace. The change is otherwise mergeable with owner awareness of this bounded recovery risk. Important Pre-merge checks failedPlease resolve all errors before merging.

Verified end-to-end against the real blocked branch, not a fixture. Took That is the last acceptance criterion on #179 — No code from that branch was executed: only its two data files were read. Ablations run by hand, each confirmed to fail for the right reason rather than merely to fail:
And the refactor is behaviour-preserving where it matters most: |
Two review findings, both the same class the generator exists to remove — a pass reporting success over input it never examined. A declared entrypointSha256 with an empty entrypoint, and a requiredRuntimeAssets entry carrying a digest but no path, were each skipped silently. With no other field stale the run then exited 0 and printed "every declared desired-state digest is already current", over a digest nothing had looked at. Both are now invalid input. The required-tool check also did not require a SHA-256 program. Without one, sha256_file simply failed and digest_for reported it as an absent target, so the run exited 1 blaming a file that was present — a misdiagnosis costing more than the failure it hid. It is an environment error and now exits 2, as documented. Each guard has a regression test, and each was ablated to confirm its test binds to it: removing the hasher check gives exit 1 instead of 2, and restoring either silent skip reproduces the exit-0-over-an-unexamined-digest it replaced.
Both findings from the previous round were assessed against the code, judged valid, and fixed in The second finding was the same defect class this PR exists to remove, one level down — a pass @coderabbitai review |

The new guards close both silent-success paths:
The self-test covers both cases and expects exit status 1. The writer and validator share the same hash helpers. The digest refresh step still runs before the plugin version bump. The current desired-state resource has resolvable digest targets. I also used the existing repository guidance about rejecting empty entrypoints and runtime-asset paths when their digest fields are declared. 🧠 Learnings usedYou are interacting with an AI system. |

Found while exercising the writer as its user: run where nothing matches, it printed "every declared desired-state digest is already current" and exited 0 while `find` had written "No such file or directory" and the loop ran zero times. Reporting success over a tree it never examined is the exact failure class this script exists to remove — the third instance of it in this PR. The enumeration is cwd-relative BY DESIGN (the self-test exercises the script against synthetic trees), so this does not anchor the cwd; anchoring it broke 11 of those cases. It counts what the loop actually saw and treats zero as an environment error (exit 2), matching the convention used for a missing tool or hasher.

User evaluation at Exercised as the user, against the real deadlock rather than a fixture:
That is the whole point of the pair working end to end, with no hand edit. The evaluation also found a real defect, now fixed in this push. Run from a directory where the enumeration matches nothing, the writer printed: Reporting success over a tree it never examined is the exact failure class this PR exists to remove — the third instance of it here, after the two CodeRabbit caught at What I did not do, and why it matters: my first attempt anchored the script to the repository root. That broke 11 of the 23 existing self-tests — the cwd-relative enumeration is deliberate, because the suite exercises the script against synthetic trees. I reverted that half and kept only the fail-closed count, which is the minimal correct fix. Baseline was 23/0; it is now 25/0. Ablation: removing the guard makes exactly the two new tests fail ( Full repo suite green (8 suites: guard 346/346, manifests 176/176, digests 25/25, classifier 18/18, surveyor-forge 19/19, plus the three |

Motivation
The daily agent-skills sync cannot produce a branch this repository will accept.
CI pins a content digest for every bundled agent, skill, and runtime asset, but nothing
here ever wrote those digests. So when the sync legitimately updates a skill, the branch
it opens fails its own required check — and re-running the sync cannot fix it, because
the sync is not what is missing.
Only a hand edit clears it, and a hand edit does not survive. Yesterday one was
force-pushed away by the next sync run six minutes later, restoring the stale value with
no signal that it had happened. This is the conduit every reviewed skill change reaches
the marketplace through, so while it is stuck, no skill update ships.
What this changes
The digests get a writer, and it runs where the branch is built — in the same follow-up
job that already bumps plugin versions — so the generated branch is correct by
construction rather than by someone noticing.
The generator and the checker now share one definition of what a file hashes to, instead
of each carrying its own copy. A generator that disagreed with the gate would leave the
branch exactly as unmergeable as having no generator at all.
No plugin content changes, so nothing shipped to consumers moves.
Fixes #179
