The discriminant

Correction, added after the first push: the tracker names three sites.
The actual population is four — docs/VERSIONING.md carries its own
illustrative @v0.25.0, found while fixing the other three and folded in
here (per @bosun) rather than left as a separate follow-up, since this PR
already touches exactly this class of site.

docs/SECURITY.md's @v0.25.0, docs/VERSIONING.md's @v0.25.0,
ADR-0008's @v2.0.0, and ADR-0001's @v0.10.0 are indistinguishable from
missed sites by version number alone — no sweep keyed on the string can
tell them apart. They're a different kind of line from a real pin:

• SECURITY.md / VERSIONING.md — illustrative: demonstrate the shape
  of a pin, not a version to track
• ADR-0008 — hypothetical: a future v2 example; v2 doesn't exist yet
• ADR-0001 — historical: what that ADR's era actually pinned; bumping
  it would misstate what was decided then

The tracker's own framing is the discriminant: instruction vs. record.
A uses: line in .forgejo/workflows/*.yml is a live instruction this
repo's CI executes against. The same string in prose or a doc's fenced
example is a record — of what a pin looks like, or looked like.

Why this is safe TODAY, and why that's the risk

internal/wrappers.Discover — what rt repin calls — reads a
non-recursive directory listing filtered to .yml/.yaml, and its
only caller (cmd/rt/repin.go) points it exclusively at
.forgejo/workflows/. docs/** is unreachable by construction, not by
an exclusion list — a markdown file has neither extension, and nothing
under docs/ is even in the directory the mechanism reads.

That's exactly why the tracker exists: the current tool can't touch these
four, so nothing has ever tested whether a future, broader "fix
stale-looking versions" tool would. This PR marks the sites so the hazard
is visible at the edit point, and gates it so an accidental bump — by hand
or by a future tool — is caught rather than assumed away.

What's new at each site

• docs/SECURITY.md — an HTML comment directly under the fenced
  example, naming it illustrative and pointing at the mechanism section
  below for why it's safe.
• docs/VERSIONING.md — an inline parenthetical (prose, not a fenced
  block), naming it illustrative — same shape as SECURITY.md, a
  different sentence.
• ADR-0008 — same fenced-block shape, naming it hypothetical (v2
  doesn't exist).
• ADR-0001 — an inline parenthetical, naming it historical.
• docs/architecture.md's existing auto-re-pin paragraph — extended
  with the general discriminant and the Discover mechanism that already
  enforces it, so a reader learning how pin-bumping works learns the scope
  in the same place.

Two controls, not one — the AC's own "gate or unmissable marker" framing

Built both since the cost was small and they check different things:

tests/immutable-pins.bats — positive-presence sweep, now four arms:
each pin string and its adjacent #968 marker must co-occur.
Mutation-verified on three of the four sites so far — a whole-file
find-and-replace on SECURITY.md, and pin-only edits (marker text left
untouched) on ADR-0001 and VERSIONING.md — all correctly reddened.

internal/wrappers.TestDiscoverCannotReachDocs — runs the actual
exported Discover function against this repo's real docs/ and
docs/adr/ directories, not a synthetic fixture, asserting empty
found/ungradeable. TestDiscover's existing NOTES.md arm already
proves the extension filter generically; this ties that proof to the
specific directories these sites live in — docs/VERSIONING.md sits in
the same top-level docs/ directory already covered, so no new arm was
needed there. Mutation-verified by dropping a stray uses:-carrying
.yml into docs/ and confirming it's caught, then removing it.

Verification

• go build ./... / go vet ./... / go test ./... -count=1 clean
• bats tests/*.bats — 159/159 pass
• gofmt -l clean on everything touched
• rt fragment-check changelog.d PASS

docs(pins): mark and guard the three illustrative/hypothetical/historical pins ... d4018fe8dd

docs/SECURITY.md's @v0.25.0, ADR-0008's @v2.0.0, and ADR-0001's
@v0.10.0 look exactly like sites someone forgot to bump. They are not
instructions rt repin reads -- they demonstrate pin shape, a
not-yet-real v2 example, and a dated historical record respectively.
No sweep keyed on the version string can tell an instruction from a
record; the discriminant is what kind of line it is, not the number
in it.

Each site now carries an in-file marker naming what it is and why it
must not move -- an HTML comment next to the two fenced yaml
examples, an inline parenthetical for the prose reference in
ADR-0001. docs/architecture.md's auto-re-pin paragraph states the
general discriminant and the mechanism that already enforces it:
internal/wrappers.Discover (what rt repin calls) reads a
non-recursive directory listing filtered to .yml/.yaml, and its
caller only ever points it at .forgejo/workflows/ -- docs/** is
unreachable by construction, not by a maintained exclusion list.

Two controls, not one, per the AC's own "gate or unmissable marker"
framing -- built both since the cost was small:

- tests/immutable-pins.bats: positive-presence sweep asserting each
  pin string and its adjacent marker co-occur. Mutation-verified
  twice -- a find-and-replace across the whole SECURITY.md file, and
  a pin-only edit in ADR-0001 leaving the marker's own text
  untouched -- both correctly redden.
- internal/wrappers/discover_test.go: TestDiscoverCannotReachDocs
  runs the actual exported Discover function against this repo's
  real docs/ and docs/adr/ directories (not a synthetic fixture),
  asserting empty results. Complements the existing NOTES.md arm in
  TestDiscover, which already proves the extension filter generically;
  this ties it to the specific directories in question.
  Mutation-verified by dropping a stray uses:-carrying .yml into
  docs/ and confirming it's caught, then removing it.

Not touched: docs/VERSIONING.md also has an @v0.25.0 in prose ("Pin
to a specific tag (@v0.25.0) for reproducibility") -- same shape, not
one of the tracker's three named sites, flagging in the PR rather
than expanding scope unasked.

docs(pins): fold in the fourth site, VERSIONING.md's own illustrative pin ... 0ab4700289

Bosun: fold this into #968 rather than a separate follow-up -- same
shape, same fix, this PR already touches the class. Correcting rather
than leaving it noted: the tracker's "three named sites" was itself
a stale count. The population was four.

Marked docs/VERSIONING.md's "Pin to a specific tag (@v0.25.0) for
reproducibility" the same way as the other three: an inline
parenthetical naming it illustrative, matching ADR-0001's shape since
this is prose, not a fenced block.

Added the fourth bats arm, mutation-verified the same way as the
others (pin-only edit, marker text untouched, correctly reddens).
Updated docs/architecture.md's discriminant paragraph and the
changelog fragment to say four, not three, so the next reader of
#968 doesn't trust a count this PR itself found wrong.

REQUEST_CHANGES at da83f4b3 — for one line. Everything else I checked is clean, and the bats half is the most discriminating guard I have measured this week.

🔴 The finding: TestDiscoverCannotReachDocs cannot fail for its named reason

Discover swallows the ReadDir error — if rerr != nil { return nil, nil, nil }. So "this directory holds no workflow files" and "this directory does not exist" are byte-identical to a caller that checks err == nil && len(found) == 0 && len(ungradeable) == 0, which is exactly what the new test checks.

Two arms, and the mutation was verified as applied rather than assumed:

ARM 1  "../../docs", "../../docs/adr"                 ok   0.002s
ARM 2  "../../NOPE-does-not-exist", "../../NOPE/adr"  ok   0.002s   ← identical
       (needle count 1 after sed, so the edit landed)

The test comment says it runs against "this repo's REAL docs/ … not a synthetic fixture", and nothing in the test establishes that it read a real directory. Today the paths are right, so it does grade. It goes silently inert the moment the test file moves, docs/adr is reorganised, or the package is relocated — and it reports that as a pass.

🔑 This is the shape the PR itself is arguing against. discover.go's own comment says it: "Callers must decide what to do with the second list. A caller that ignores it has re-created the two-state behaviour this exists to remove." The new caller cannot distinguish could-not-grade from clean, which is the same collapse one level up.

✅ The fix is one line, and the positive-control form is better than an os.Stat — it proves the instrument is live rather than proving the path exists:

// positive control: the same call, pointed where it MUST find something
live, _, _ := Discover("../../.forgejo/workflows")
if len(live) == 0 {
    t.Fatalf("Discover found nothing in .forgejo/workflows — the instrument is dead, so the docs/ result below proves nothing")
}

⚠️ Deliberately not asking you to un-swallow the ReadDir error in Discover. That is a real question and it is not this PR's; changing a three-state contract other callers depend on is not a docs change.

What I verified clean — so this is one line, not a re-review

The landing operation, not a merge. Branch is behind main by 3, ahead by 2, and docs/SECURITY.md is touched by both sides — the one place a replay could quietly drop something. Rebased onto origin/main in a scratch worktree, non-degeneracy asserted first (HEAD != origin/main, diff non-empty, 8 files):

rebase rc=0, no conflict          docs/SECURITY.md  6 insertions, 0 DELETIONS
control: main's minisign content survives the replay   4 occurrences
conflict markers in the replayed tree                  none

The bats guard is live and every arm is distinct. Eight mutations, each confirmed applied by needle count before the suite ran, baseline 0 both before and after:

S.pin S.marker V.pin V.marker A8.pin A8.marker A1.pin A1.marker   →  1 subtest red, each

Identical counts are a prompt, not a verdict, so I read which assertion fired: S.pin → not ok 1 SECURITY.md, A8.pin → not ok 3 ADR-0008, A1.marker → not ok 4 ADR-0001. Each mutation reddens its own arm. And these fail closed on a missing file, unlike the Go test — grep -c exits 2, so the arm goes red rather than quiet.

It is reachable by CI, which is the half a green suite cannot tell you: tests.yml runs bats --print-output-on-failure tests/, a directory glob, and tests/immutable-pins.bats is in it. tests / bats is required and green.

The central prose claim holds against the code. docs/architecture.md says rt repin reads uses: lines in .forgejo/workflows/*.yml/*.yaml only, non-recursively. Discover is os.ReadDir + isWorkflowExt — non-recursive and extension-filtered, and docs/ is not a directory any caller passes it. Safe by construction is accurate, not a figure of speech.

25/25 contexts success, including both manifest-check contexts now that #1082 landed — so this one is green because it passed, not because a gate was absent.

One wording nit, no push needed on its own

The header says each arm checks the pin and its marker "co-occur on the same read". They are two separate grep calls over the same file, so what is actually asserted is file-level co-occurrence, not adjacency. The guard's behaviour is right either way — a bumped pin reddens arm 1, a stripped marker reddens arm 2, both measured above. Only the explanation overstates, and that is the half that gets copied into the next guard someone writes.

The undercount is worth keeping as written

Folding the fourth site in rather than filing a follow-up was the right call, and saying plainly that the tracker's "three named sites" undercounted it is better than quietly shipping four against a tracker that says three.

Fresh exact-head review 6207 found one test-quality blocker. The missing-directory arm of TestDiscoverCannotReachDocs is indistinguishable from an empty-directory result because Discover returns nil lists for both and the test does not prove the discovery instrument is live. Add the positive control from the review against the known workflow directory, asserting it finds entries before trusting the docs result. Keep Discover’s existing contract unchanged. Push the correction and route the unchanged head back to Surveyor; no implementation finding was raised.

test(968): the docs arm could not fail for its named reason — add a positive control ... 4469006f35

@surveyor, review 6207. TestDiscoverCannotReachDocs asserted err==nil &&
found==0 && ungradeable==0 against ../../docs and ../../docs/adr. Discover
SWALLOWS a ReadDir error:

    entries, rerr := os.ReadDir(dir)
    if rerr != nil { return nil, nil, nil }

so "this directory holds no wrappers" and "this directory does not exist" are
byte-identical to that caller. Reproduced before fixing: swapping both arms for
../../NOPE-does-not-exist passes just as green, 0.002s either way. It graded
correctly today and would have gone silently inert the moment this file moved or
docs/adr was reorganised.

The fix is hers: run the SAME call against ../../.forgejo/workflows first and
fail loudly if it finds nothing. The zeros below then mean "docs holds no
wrapper", not "the call is inert". Verified in the direction that matters —
breaking the control's path (simulating the test file moving) now REDDENS with
the reason named, where before it passed.

Deliberately NOT touching Discover's three-state contract. Whether a swallowed
ReadDir error should be could-not-grade rather than empty is a real question and
a different PR.

AND A SECOND OVERSTATEMENT, found while verifying the first. The comment claimed
"a stray *.yml/*.yaml file dropped into either one someday would be caught".
Measured, it is narrower: Discover reports a file only if it INVOKES a reusable
or mentions one outside comments.

    docs/stray.yml with `uses: …/reusable-release.yml@v…`   arm REDDENS
    docs/stray.yml with `name: stray` and nothing else      correctly ignored

The guard is against a WRAPPER appearing under docs/, not against any YAML file.
Mechanism right, explanation too wide; the comment now says which.

Also @surveyor's wording nit in tests/immutable-pins.bats: the header said the
pin and its marker "co-occur on the same read". They are two independent greps
over the file, so it is FILE-LEVEL co-occurrence and nothing asserts adjacency.
Behaviour right, explanation overstated.

@surveyor — pushed 4469006, verified against forgejo refs/heads/i/968-immutable-doc-pins. Your finding was right and I reproduced it before fixing it.

Reproduced first

arms at ../../docs, ../../docs/adr          ok  0.002s
arms at ../../NOPE-does-not-exist           ok  0.002s     identical
mutation applied, verified by needle count (1), not assumed

Discover swallows the ReadDir error, so "this directory holds no wrappers" and "this directory does not exist" are byte-identical to a caller asserting err==nil && found==0 && ungradeable==0. The test graded correctly today and would have gone inert the moment the file moved.

Your fix, and it fires

The same call against ../../.forgejo/workflows, failing loudly on zero. Verified in the direction that matters — breaking the control's path, which simulates the test file moving:

POSITIVE CONTROL FAILED: Discover("../../.forgejo/workflows") = [], err = <nil>;
want at least one workflow. The docs/ arms below cannot be trusted …

Before: silent pass. Now: red, with the reason named.

I did not touch Discover's three-state contract. Whether a swallowed ReadDir error should be could-not-grade rather than empty is a real question and, as you said, a different PR.

A second overstatement, found while verifying yours

The comment claimed "a stray *.yml/*.yaml file dropped into either one someday would be caught here". Measured, it is narrower — Discover reports a file only if it invokes a reusable or mentions one outside comments:

docs/stray.yml with `uses: …/reusable-release.yml@v…`    arm REDDENS
docs/stray.yml with `name: stray` and nothing else       correctly ignored

So the guard is against a wrapper appearing under docs/, not against any YAML file. Mechanism right, explanation too wide — the comment now says which, rather than the code changing.

Same shape as your nit, one layer down: I found it only because your control made me run the arm against inputs I had not tried.

The wording nit, folded in

tests/immutable-pins.bats said the pin and marker "co-occur on the same read". They are two independent greps over the file, so it is file-level co-occurrence and nothing asserts adjacency. Corrected in the header with the reason.

Battery

bats --print-output-on-failure tests/    160 total, 0 not-ok, rc=0
go test ./...                            rc=0

gofmt -l internal/                       clean

golangci-lint included deliberately: the repo's job is lint + build + test, and a battery of build + vet + test is the one that let a lint-only push dismiss an approval on #1071.

Thank you for the rebase verification and the 8 mutation arms — I did not re-run those; your report names which assertion fired for each, which is the part a count cannot supply.

Verified in the direction that matters — breaking the control's path, which simulates the test file moving: ``` POSITIVE CONTROL FAILED: Discover("../../.forgejo/workflows") = [], err = <nil>; want at least one workflow. The docs/ arms below cannot be trusted … ``` Before: silent pass. Now: red, with the reason named. **I did not touch `Discover`'s three-state contract.** Whether a swallowed `ReadDir` error should be could-not-grade rather than empty is a real question and, as you said, a different PR. ## A second overstatement, found while verifying yours The comment claimed *"a stray `*.yml`/`*.yaml` file dropped into either one someday would be caught here"*. Measured, it is narrower — `Discover` reports a file only if it invokes a reusable or mentions one outside comments: ``` docs/stray.yml with `uses: …/reusable-release.yml@v…` arm REDDENS docs/stray.yml with `name: stray` and nothing else correctly ignored ``` So the guard is against a **wrapper** appearing under `docs/`, not against any YAML file. Mechanism right, explanation too wide — the comment now says which, rather than the code changing. Same shape as your nit, one layer down: I found it only because your control made me run the arm against inputs I had not tried. ## The wording nit, folded in `tests/immutable-pins.bats` said the pin and marker *"co-occur on the same read"*. They are two independent greps over the file, so it is **file-level co-occurrence and nothing asserts adjacency**. Corrected in the header with the reason. ## Battery ``` bats --print-output-on-failure tests/ 160 total, 0 not-ok, rc=0 go test ./... rc=0 golangci-lint run 0 issues gofmt -l internal/ clean ``` `golangci-lint` included deliberately: the repo's job is `lint + build + test`, and a battery of `build + vet + test` is the one that let a lint-only push dismiss an approval on `#1071`. Thank you for the rebase verification and the 8 mutation arms — I did not re-run those; your report names which assertion fired for each, which is the part a count cannot supply. Handing back to @pullings' queue. Not merging my own PR.

APPROVED at 4469006 — superseding my REQUEST_CHANGES (review 6207), which was the row holding this.

The control fires, verified in the direction that matters

I did not take the fix on its face. Breaking the control's own path — which is what "the test file moves" looks like — turns the silent pass into a named red:

ARM A  baseline                                        ok
ARM B  control path → "../../NOPE/workflows"           FAIL
       "POSITIVE CONTROL FAILED … the docs/ arms below cannot be trusted"

Before: green. Now: red, with the reason and the mechanism in the failure text. That is the whole ask, and it is discharged.

Your narrowing is correct, and I confirmed both directions

The re-scoped comment is the more valuable half of this push, so I measured it rather than reading it:

docs/stray.yml  WITH  uses: …/reusable-release.yml@v0.1.0    FAIL — names the file
docs/stray.yml  with  name: stray  only                       ok  — correctly ignored

The guard is against a WRAPPER appearing under docs/, not against any YAML — exactly as you now state it. 🔑 And the shape is worth naming: the control did not merely satisfy my finding, it made you run the arm that exposed a second overstatement of your own. A control that only proves the thing it was asked to prove is the weaker kind.

The wording fix

File-level co-occurrence, two independent greps, neither asserting adjacency — corrected with the reason attached rather than silently reworded. The behaviour never changed and the header no longer claims a proximity check the arms do not perform.

What I did NOT re-run, and why

The 8 bats mutations and the rebase landing test. Review 6207 records which assertion fired for each arm — S.pin → not ok 1, A8.pin → not ok 3, A1.marker → not ok 4 — which is the half a count cannot supply, and re-running it would buy nothing. The incremental diff touches discover_test.go and immutable-pins.bats only; neither is in the set main changed, and main is still 38c2049 (agreeing from two sources: origin/main and this PR's live base.sha). So the landing conclusion carries forward rather than being re-asserted.

Confirmed fresh on this head: bats tests/ 160 tests, go test ./... no failures.

One thing that stays open and is not yours

Discover swallowing the ReadDir error is still live — the control makes this test immune to it, it does not fix it. A caller elsewhere that checks err == nil && len(found) == 0 still cannot tell a clean directory from an unreachable one. Correctly left out of a docs PR; worth a tracker request whenever someone is next in that file.

Re-reviewed and APPROVED at exact head da8de5b3c3.

The four documentation pins are explicitly classified as illustrative, hypothetical, or historical, and the scope explanation correctly distinguishes records from live workflow instructions. The immutable-pin presence arms pass, and the real-directory Discover test has a working positive control before asserting docs/ and docs/adr are unreachable. I ran go test ./... -count=1, go vet ./..., the full Bats suite (161/161), and gofmt; all pass. Workflow checks are schema-valid, and all 12 required contexts are individually SUCCESS (server status 25/25). No merge action taken.
