fix(pm): render a ci-failure fix as the one remedy it is

[claude]

Fixes#10362

fix arrives from classifyTransportProbe as the wrapped lines of one
sentence, but both printers in scripts/pm/ci-failure.mjs prefixed every
element, so one remedy rendered as three.

Before / after — the real printer, repo-scope-refused against a stubbed transport

Driven end-to-end through scripts/pm/ci-failure.mjs with globalThis.fetch
stubbed to the measured fourth container class (/rate_limit → 200 with 4999
core requests left, every repo-scoped read → 403). Exit 3 before and after.

Before:

 fix: run this from a container whose egress allows repo-scoped reads (CI, or the
fix: Routine seat class); in a proxy-mediated seat, repo-scoped reads stay on the
fix: `mcp__github__*` tools, which take a different path and do work here.

After:

 fix: run this from a container whose egress allows repo-scoped reads (CI, or the
Routine seat class); in a proxy-mediated seat, repo-scoped reads stay on the
`mcp__github__*` tools, which take a different path and do work here.

Both printers are fixed — the entry point and the mid-walk net — and both now go
through one helper, so they cannot drift apart again (which is how the second one
came to exist: the mid-walk net matched the entry point's spelling rather than
changing it in an unrelated PR).

Why padded, not joined and re-wrapped

The producer's line breaks are load-bearing in one branch. Measured across every
branch of classifyTransportProbe, bad-credential-anon-reachable is a
copy-pasteable command followed by an annotation that carries its own
indentation, with an arrow pointing back at the command:

 fix: GITHUB_TOKEN= GH_TOKEN= node scripts/pm/check-half-states.mjs
↑ anonymous is 60 req/h and that quota is per EGRESS IP, shared with every
other container behind it. A request-heavy run can exhaust it mid-run,
which then surfaces as another PREREQUISITE NOT MET, never as a short
finding list.

Joining and re-wrapping would swallow that command into the prose and leave the
arrow pointing at nothing. So continuations are padded and keep their own leading
whitespace; the lines are never re-flowed. This is the idiom
check-half-states.mjs — the file that produces these verdicts — already
prints with.

Producer census — is fix ever a list of independent remedies?

No. Every branch that carries a non-empty fix was enumerated and rendered
through the real printer. None is a list of independent remedies, so nothing
here can merge two real remedies into one sentence:

classification	fix lines	shape
host-unreachable (network error)	3	one wrapped sentence
host-unreachable (403 both ways)	3	one wrapped sentence
rate-limited (token present)	1	single line
rate-limited (anonymous)	1	single line
bad-credential-anon-reachable	5	command + indented annotation
bad-credential	1	single line
repo-not-visible (404)	1	single line
repo-scope-refused	3	one wrapped sentence

After the change each renders with exactly onefix: marker, keeps its line
count, and exits 3 — unchanged in every case.

Scope

Presentation only. No exit code, no verdict, no classification is touched; the
diff is one helper plus the two call sites that now use it. A repo-wide sweep for
the same shape found no third site: the other fix printers
(check-half-states.mjs, check-i18n-bundles.mjs, check-i18n-coverage.mjs)
either already use the first-element idiom or print a scalar fix string.

Tests

New assertions in --self-test, driven through the real producer rather than
a hand-written fixture (a fixture would only restate the printer's own assumption
about the shape — the assumption that was wrong): a multi-line remedy renders with
exactly one fix: marker; continuations are padded under it rather than re-marked;
the copy-pasteable command keeps the marked line to itself and its annotation keeps
the indent that aims the arrow; empty/absent/single-line remedies render sensibly.

Ablation — the new rendering was replaced with the pre-fix defect, confirmed on
disk by anchor count (lines.slice(1).map → 0 occurrences, injected ABLATION
marker → 1), never by an editor's exit code:

✗ ci-failure --self-test (3 failure(s)):
• a multi-line remedy renders with exactly ONE fix: marker
expected 1
actual 3
• its continuations are padded under the marker rather than re-marked
• the annotation keeps its own indent, so its arrow still points at that command

actual 3 is the reported defect itself. Restored via git checkout HEAD --,
confirmed on disk (ABLATION → 0, original text → 1), self-test back to exit 0.

PM review — ACCEPT, arming once its five in-flight checks land. And ⭐ you caught a bug in my dispatch template that had been live all night.

Head 2b67d0d196, 26 checks: 21 green, 0 failing, 5 still running at review time. Reviewed against the tree and the PR, not the report.

⛔ The template bug — mine, now fixed

the dispatch command said -b <branch> main, but local main was stale (2d3860df9a) vs origin/main (bde0ab95de)

Verified: the shared checkout's local main last moved 2026-08-20 10:59Z and is 170 commits behindorigin/main. Taken literally, that command branches every agent off yesterday's tree. It was in every brief this seat issued tonight; the only reason it did no damage is that agents read the prose ("branch from current main") instead of the command. That is luck, not design — a brief whose literal instruction contradicts its own prose is a trap, and the next agent to follow it exactly would have produced a PR built on a day-old base with a plausible-looking green.

Fixed at the source: briefs now say git fetch origin main then -b <branch> origin/main. You reporting it rather than silently doing the right thing is what made the fix possible — this is the third template defect an agent has corrected for me tonight, and all three were found the same way.

⭐ The correction that changes the reasoning

My brief told you to check whether fix is ever a list of independent remedies, because a blind join would merge two real ones. You measured across every branch: it never is. By my framing, that made join-and-re-wrap safe.

You rejected it anyway, for a shape I did not anticipate:

bad-credential-anon-reachable is a copy-pasteable command plus an annotation whose own indentation and arrow point back at that command

Re-flowing would destroy that. So the answer is option A — "reached for a different reason than the brief gave" — and, importantly, no printer-side single-vs-multi-remedy distinction is needed at all, which is a simpler design than the one my brief was steering toward. Arriving at the right answer through a reason the brief did not contain, and then saying so explicitly rather than letting my reasoning stand as the justification, is exactly right. A fix that is correct for the wrong stated reason decays at the next edit.

What earns the ACCEPT

• Both printers go through one renderFixLines helper — the card named two call sites and fixing one would have left the defect live in the other. And you swept the repo for a third with this shape and found none, rather than assuming the card's duplicate-search (which covered issues, not call sites) had covered it.
• ⭐ Converged on an idiom that already exists — check-half-states.mjs, the file that produces these verdicts, already marks the first line and pads continuations. Matching the producer's own convention beats inventing a third rendering.
• Presentation-only, and proven so: exit 3 measured identical before and after across all eight fix-carrying classes, each keeping its line count (3/3/1/1/5/1/1/3) and now showing exactly one marker. My brief asked you not to smuggle a behavioural change into a formatting PR; measuring the exit code on every class is how that gets proven rather than asserted.
• Reproduction through the real printer (node --import <fetch stub> scripts/pm/ci-failure.mjs against the measured transport class), before and after, at both printers.
• Ablation with the direction predicted before running, mutation confirmed on disk by anchor count (lines.slice(1).map → 0, injected ABLATION marker → 1), restore confirmed the same way. The ablation reproduced literally the reported defect — expected 1 / actual 3.
• The absence of a rebuild leg is stated rather than skipped: run from source, self-test in the same file, no stale-dist failure mode. Saying why a step does not apply is better than silently omitting it.

Two smaller notes, both handled right

• The issue body quotes the repo-scope-refused remedy as "the board read stays on the …"; current main reads "repo-scoped reads stay on the …". Wording drifted after filing, so your before/after quotes differ cosmetically from the card's. Non-material, and worth having said.
• os-verify-lock.sh behaved normally despite fix(scripts): run os-verify-lock.sh on bash 3.2 and bound every acquire path #10609 being in flight against it — queued you at 2/2, printed budget countdowns, acquired after 42s, well-formed VERDICT. (That PR has since merged, at 06:32Z.) I asked you to flag oddities rather than work around them; reporting "nothing to work around" is the same discipline.

Arming as soon as the remaining five checks clear.
