* Attribute every paid trial's cost: bind label-named records by testName, price aborted SDK sessions from streamed usage, model-free cases cost $0

Co-authored-by: capy-ai[bot] <230910855+capy-ai[bot]@users.noreply.github.com>

* feat(flaky): gstack-flaky run reruns a failed JUnit test once and ledgers the flake (GSTA-158)

Co-authored-by: capy-ai[bot] <230910855+capy-ai[bot]@users.noreply.github.com>

* fix(flaky): stream output, keep unreported runner failures red, fail-closed duplicates and nonzero reruns

Co-authored-by: capy-ai[bot] <230910855+capy-ai[bot]@users.noreply.github.com>

* fix: pre-landing review fixes

gstack-flaky never greens an incomplete run: a targeted rerun needs the
runner's summary proving the first run complete, otherwise (and always for
generic runners) the rerun repeats the whole command. A rerun clears a test
only when it exits 0 and the test passes once on its first attempt. Killed
runners exit 3 (FLAKY_COMMAND_KILLED) and signals are forwarded. The first
report is restored at --junit with reruns kept beside it; ids are redacted at
every output; the ledger gets its own GSTACK_FLAKE_LEDGER_JUNIT; fixtures are
registered in FREE_FIXTURES.

* fix: latch cancellation and check whole-command rerun reports

A cancel forwarded to a runner that traps the signal now counts as killed for
every later attempt, so a cancelled job is never rerun or greened. A
whole-command rerun clears nothing when its report has a failed test, misses a
first-run test, or its runner counted failures outside the report.

Co-authored-by: capy-ai[bot] <230910855+capy-ai[bot]@users.noreply.github.com>

* fix: whole-command rerun when coverage or runner-flaky tests can fail the run

A coverage threshold or a fail-on-flaky policy fails a run for a reason a
narrowed rerun cannot reproduce, so either forces a whole-command rerun.
--junit refuses an existing file that is not a JUnit report instead of
deleting it.

Co-authored-by: capy-ai[bot] <230910855+capy-ai[bot]@users.noreply.github.com>

* feat(flaky): rerun the whole command by default; targeted rerun is opt-in

A rerun counts only on the runner's own full green verdict: exit 0, no failed
or missing test, nothing counted outside the report. That covers every way a
run can fail, which a narrowed rerun cannot (a coverage threshold with an lcov
reporter, a fail-on-flaky policy, a test never reached). --rerun-scope test
reruns the failed test alone, with its preconditions documented and the
complete-run checks kept as a safety net. An unreadable existing --junit file
is a usage error, not a crash.

Co-authored-by: capy-ai[bot] <230910855+capy-ai[bot]@users.noreply.github.com>

* fix(flaky): reword the FLAKY_QUARANTINE_BASE hint so the egress scanner does not read it as a network op

Co-authored-by: capy-ai[bot] <230910855+capy-ai[bot]@users.noreply.github.com>

* test(agent-sdk): every SDK caller passes the claude_code preset or names why not

The SDK's default system prompt is a bare stub that drops the line telling the
model to run /skill through the Skill tool. runAgentSdkTest now refuses a
missing, empty or bare-string prompt; non-preset callers name a reason; a free
tripwire scans test/ and scripts/ for the same mistake.

Co-authored-by: capy-ai[bot] <230910855+capy-ai[bot]@users.noreply.github.com>

* test: record the SDK prompt guard as a non-behavioral harness change and baseline its tripwire

harness-version: runAgentSdkTest validates systemPrompt before starting; every
live caller already passed the claude_code preset, so no verdict can change.
test-of-test ratchet: the tripwire's subject is the eval harness by design.

* docs: name the preset literal callers pass and the unnamed-prompt refusal

* feat(eval-plan): frontier models under test (R54)

Haiku and Sonnet are not models under test. dry-run refuses a plan whose every
arm is Haiku or Sonnet unless --tier-question names what it asks about that
tier, warns on a mix, and re-costs the plan on Opus 5.5 and GPT-6.1 Sol.

Co-authored-by: capy-ai[bot] <230910855+capy-ai[bot]@users.noreply.github.com>

* fix(eval-plan): trim R54 skill prose and raise the eval-plan context ceiling

The R54 paragraph and CHECK: frontier bullet were cut to the minimum; the
exemptions and verdict rule stay in docs/TESTING_INTERNALS.md. The remaining
growth is the feature, so only the eval-plan eager ceiling moves (4887 -> 5458,
the capture helper's value); other skills' ceilings are left as they were.

Co-authored-by: capy-ai[bot] <230910855+capy-ai[bot]@users.noreply.github.com>

* fix(eval-plan): pilot start keeps the R54 refusal; --tier-question rejects a flag

Review pass 1 (full depth) found the frontier refusal could be skipped by
starting a pilot on Haiku or Sonnet arms behind a dry run made on other arms,
or behind a dry-run.json written before the check existed. startPilot now
refuses a pilot whose every arm is Haiku or Sonnet unless its dry run recorded
a tier question. dry-run --tier-question no longer takes the next flag as its
answer. The testing doc now says the frontier re-cost is printed for
comparison with the brief cap, not enforced.

* docs(support-tiers): Windows CI in the present tense now that windows-smoke is required (#3806)

Co-authored-by: capy-ai[bot] <230910855+capy-ai[bot]@users.noreply.github.com>

* chore: empty commit for a clean check set at the same tree (cancelled orphan free-suite check at 97487df)

Support tiers

gstack has two support tiers. Full support gets the whole test suite, paid evals and new work. Minimal support means gstack is not totally broken, and nothing more. Garry Tan set this on 2026-11-01: "we don't want it to be totally broken, but we just don't need to invest that much into it."

Full support

  • Operating systems: macOS and Linux.
  • Models: Claude and OpenAI models, both as the host agent and as a reviewer.
  • Testing: the full free suite and the paid evals.

Minimal support

  • Windows (Git Bash or MSYS): with a default Git for Windows install, ./setup installs, and the core skills start without errors. The core skills are /ship, /review, /qa-only, /investigate and /browse on gstack's own browser. One required CI job, windows-smoke, checks this on every pull request (see Windows CI below).
  • Gemini models: the core workflows run to the end without errors when Gemini is the host agent or a reviewer. We check this by hand or with one cheap smoke run, not with an eval cell.

That is the whole promise. Other skills, optional parts such as /cso's native helper, non-default shell settings and speed are not covered.

What we stop doing

  • No Windows-only or Gemini-only features, parity work, tuning or polish.
  • No new Windows or Gemini CI jobs or eval cells. Windows CI tuning stops.
  • A Windows-only or Gemini-only report that doesn't break install, startup or a core workflow closes as won't fix (triage rules), with a link to this page. A report that does break one of them gets a small fix.

Windows CI

  • windows-smoke is the required Windows check on pull requests.
  • The six-shard Windows free suite (the Windows Free Tests workflow, windows-free-tests) runs nightly on main, or when someone starts it by hand, and never blocks a pull request.
  • A red nightly run gets a fix only when it shows an install, startup or core-workflow break.

What doesn't change

These tiers don't change which models gstack's own evals test, or which cross-family review voice gstack uses.
