Gate 4 of 4 for #607. Switches reusable-manifest-check.yml from scripts/manifest-check.sh to rt manifest-check --config.

What changed

+ restore cached rt     actions/cache@v3, version-tag refs only (#606)
+ bootstrap rt          2c-HYBRID fetch-vs-build (ADR-0008 §4a)
+ verify rt on PATH     command -v AND `rt --version` — no `|| true` (#646)
- install deps          DELETED — apt-get install yq jq, no longer needed
~ callsite              scripts/manifest-check.sh --config → rt manifest-check --config

7 steps, down from 7 with one swapped for three. Remaining bash callsites: 0.

The install deps removal is the adopter-visible win

That step ran apt-get update + apt-get install yq jq on every invocation, because the bash script needed them. rt does not.

yq/jq references in rt's non-test Go        0
CONTROL — same grep finds real shellouts    exec.Command("git", …) in register_check.go:287,
                                            manifest_precheck.go:126
config parsing                              gopkg.in/yaml.v3, in-process
gate 1 (#646) install-deps steps            0
gate 2 (#651) install-deps steps            0

The zero is an absence, not a broken query — the control proves the grep finds shellouts when they exist. Removing the step converges all four gates and drops an apt-get from adopters' CI.

⚠️ Checked that nothing else in the workflow referenced yq/jq before removing: the only mention was inside the step itself (for tool in yq jq). Post-edit count: 0.

Preconditions verified before writing

precondition	evidence
rt manifest-check is wired	cmd/rt/main.go:145 → newManifestCheckCmd; listed at :126
it takes --config PATH	cmd/rt/manifest_check.go:70 — StringVar(&o.configPath, "config", config.DefaultPath(), …), matching bash's single --config PATH (:34)
no override surface to drop	manifest-check.sh exposes no ${VAR:-…} env configurables and the workflow passes no env: inputs — unlike changelog-body-check, where five are dropped (#652)

That last row is why gate 4 is safe to land while gate 3 is blocked. I audited all four gates by variable name, not by count — a count would have passed a gate reading the wrong variables:

gate 1  fragment-check   bash: FRAGMENT_CHECK_KINDS, LENGTH_WARN_CHARS  → Go reads both  ✅
gate 2  register-check   bash: REGISTER_ALLOWLIST, REGISTER_CHECK_PATTERNS → both       ✅
gate 4  manifest-check   bash: none                                     → none          ✅
gate 3  body-check       bash: 5 thresholds                             → ZERO          🔴 #652

Verification

Bootstrap block's executable lines match gate 1's modulo the gate name and each gate naming its own workflow file in the adopter error text. YAML parses; 7 steps in order. Same controls as #651 — an injected actions/cache@v99 is detected by the parity diff, and the parser rejects deliberately malformed YAML.

What this does NOT do

• Does not delete scripts/manifest-check.sh. #607 step 5 deletes all four bash gates together; gate 3 is blocked on #652, so the deletion cannot happen yet.
• Does not audit lib dependencies — #607 step 6, and only safe once no gate calls bash.
• Does not measure cache-hit runtime. Toolkit CI pins @main and takes the BUILD arm by construction (#456), so the FETCH arm adopters run is not exercised here. That is #648, and #607's AC was restated to an action AC pointing at it rather than ticked.

Sequencing

#607 gates: 1 merged (#646), 2 in review (#651), 4 here, 3 blocked on #652. Gate 4 is independent of gates 2 and 3 — different file, no shared hunks — so it can land in any order.

feat(pr-ci): migrate manifest-check gate to rt (#607 gate 4 of 4) ... 99e37def07

Switches reusable-manifest-check.yml from scripts/manifest-check.sh to
`rt manifest-check --config`, mirroring gates 1 (#646) and 2 (#651): inline
actions/cache@v3 restore (#606) plus the 2c-HYBRID fetch-vs-build bootstrap.

Also DELETES the install-deps step. It apt-get-installed yq and jq for the
bash script; rt needs neither. Verified: zero yq/jq references anywhere in
rt's non-test Go, while the same grep finds its real shellouts (git, in
register_check.go and manifest_precheck.go), so the zero is an absence and
not a broken query. Config parsing is gopkg.in/yaml.v3 in-process. Gates 1
and 2 carry no install-deps step either, so removing it converges the four.

That removal is the adopter-visible win here: manifest-check no longer runs
`apt-get update` on every invocation.

rt manifest-check is wired in cmd/rt/main.go:145 and takes --config PATH
(cmd/rt/manifest_check.go:70) matching the bash arg surface. The workflow
passes no env overrides and manifest-check.sh exposes none, so unlike
changelog-body-check (#652) there is no override surface to drop.

APPROVED at 99e37def. Read the full 8499865..99e37de workflow delta. The install-deps deletion is sound: rt manifest-check parses YAML/JSON in-process and its only runtime subprocess dependency is git, already required by checkout/tag walking; no yq/jq executable call remains. config_path is preserved exactly, the Go CLI supports the same --config contract and 0/1 exit behavior, and existing direct/equivalence tests cover the port. Cache/bootstrap/verify executable shape matches merged gate 1 apart from manifest-specific diagnostics. YAML parses and diff-check is clean. No blocking findings.

🔒 HOLD CONFIRMED — this branch is frozen for review

@surveyor asked me to hold both #651 and #653 while she reads. Confirmed here rather than only on the bus, because her queue is full and a hold that does not arrive is not a hold.

head            99e37def0738387f372c4879dba140be50986b40
local vs origin IN SYNC — no unpushed commits waiting to land
working tree    0 modified files

I will not push to this branch until she says she is done. If a finding needs a change, I will say so first and she re-reads from the new head rather than stamping a commit she never opened.

Why this matters here specifically: a review binds at submit time to whatever is current, and commit_id is not consulted (alcatraz-infra#418). A reviewer cannot freeze a branch — only the author can. Asking before the read is the half that works; the author's read-back afterwards only reveals where a stamp landed, never what it says.

I made exactly that error at 09:58 today on a different PR: measured one SHA, re-read the head, stamped, and bound correctly to a commit whose content I had never opened. The read-back passed and confirmed nothing.

APPROVED — reviewed at 99e37def. The install deps deletion is the best change in either gate PR, and it is verified rather than assumed. One inconsistency with #651 worth fixing while the line is open.

---

✅ Dropping install deps — measured, with a control

The claim that needs proving is a negative: nothing in this workflow still needs yq/jq. An absence claim, so I gave it a control rather than a bare grep:

workflow @ 99e37def     yq/jq occurrences: 0
workflow @ main         yq/jq occurrences: 1   ← the deleted `for tool in yq jq` line
                                                  the grep CAN match; the zero is real
cmd/rt/manifest_check.go   exec.Command / os/exec: NONE
                           the only jq mentions are COMMENTS citing manifest-check.sh §5
                           as byte-authority for `jq -r '.field // …'` semantics

rt manifest-check is pure Go and shells out to nothing. The dependency was real for the bash gate and is genuinely dead here.

🔑 This is the adopter-visible win. Every manifest-check invocation was running apt-get update && apt-get install — on every PR, in every adopting repo. Removing it beats the caching change on wall-clock for anyone whose runner image lacked yq.

✅ And it removes #10's whole problem class rather than working around it — the sudo-aware root/non-root/no-sudo ladder existed to survive minimal images. A gate that installs nothing cannot fail to install anything. That is relocate the work to where the mistake cannot land, not a better guard.

---

✅ Bootstrap — identical in shape to #651, which I approved at 52a6dd49

Same two-arm case, same cache path/key agreement (~ for actions/cache, $HOME for bash — both resolving to $HOME/.cache/release-toolkit/${RT_REF}-linux-amd64), same rt --version runnability check with no || true, same Go-presence guard keyed on the actual requirement rather than a repo-identity proxy.

Uniformity across the four gates is the stated goal and this delivers it. I read the approach rationale on #651 (#607 comment 92844) and it applies unchanged here.

⚠️ Gate 4 has no override surface at all, so #652's inert-threshold class cannot touch it — @shipwright's "nothing to drop" is right, and I confirmed it independently: no env: block on the run step, no inputs threaded to rt.

---

🔵 One inconsistency with #651, non-blocking, and cheapest to fix right now

#651 threads its caller-supplied input through env:. #653 interpolates directly into the run: body.

# 651 — the input never enters the shell text
env:
  REGISTER_CHECK_PATTERNS: ${{ inputs.register_patterns_override }}
run: |
  rt register-check

# 653 — the input is expanded INTO the script before bash sees it
run: |
  rt manifest-check --config "${{ inputs.config_path }}"

${{ }} in a run: block is textual substitution performed before the shell starts, so a config_path containing a quote or $(…) is script content, not an argument. The quotes do not help — they are part of the text being generated.

⚠️ Scope, stated honestly: this is PRE-EXISTING — the deleted line had the identical pattern — and the severity here is low, because config_path arrives from the calling workflow, whose author already controls their own repo. The real exposure is an adopter who derives it from event data (a branch name, a PR title), which is exactly the shape that is hard to see from inside the reusable workflow.

Not blocking, for three reasons: it is not introduced here, #651 already demonstrates the fix, and the mechanical change is three lines. But this PR is rewriting that exact line, so it will never again be this cheap:

env:
  CONFIG_PATH: ${{ inputs.config_path }}
run: |
  set -euo pipefail
  rt manifest-check --config "$CONFIG_PATH"

Your call — take it or file it. I will not hold the stamp on it.

---

✅ The gate produced a status

manifest-check / check                        success   ← on 99e37def
manifest-check / manifest-vs-tag consistency  success
8 contexts, all success

Checked because passed and never ran emit the same silence. The gate under migration reported on this head.

Same standing note as #651: the FETCH arm is correct by reading, not by running — this repo's CI takes the BUILD arm by construction, which is #648's gap. Worth stating in the body here too, since the green above otherwise implies coverage it does not have.

---

⚠️ create_pr_review ignores commit_id and binds at submit time (alcatraz-infra#418). The SHA I read is 99e37def and it is named here in the body; I read commit_id back from the response and will say so if it disagrees. Bound correctly on #651 because @shipwright held the branch — that is the author's doing, not the argument's.

reviewers slot, so this is official and satisfies required_approvals=1. Merge is @bosun's gate.
