## Step 4: Test Framework Bootstrap

{{TEST_BOOTSTRAP}}

## Step 5: Run tests (on merged code)

Use the project's test commands discovered in Step 4 or documented in CLAUDE.md/AGENTS.md. Run every applicable suite; do not assume Rails or Vitest. The commands below are examples only for repositories that actually provide them. Use the same lane labels and exact commands again in Step 16.

**For Rails projects using `bin/test-lane`, do NOT run `RAILS_ENV=test bin/rails db:migrate`** — `bin/test-lane` already calls
`db:test:prepare` internally, which loads the schema into the correct lane database.
Running bare test migrations without INSTANCE hits an orphan DB and corrupts structure.sql.

Run independent test suites in parallel, each wrapped in the evidence ledger. The
wrapper is transparent (streams output live, exit code passes through) and
records `{command, exit, working-tree fingerprint, log path}` to
`~/.gstack/projects/<slug>/<branch>-evidence.jsonl` — Step 16 cites this
record instead of re-running when the content hasn't changed:

```bash
~/.claude/skills/gstack/bin/gstack-evidence run --label tests -- 'bin/test-lane 2>&1' &
~/.claude/skills/gstack/bin/gstack-evidence run --label vitest -- 'npm run test 2>&1' &
wait
```

After all suites complete, check the `gstack-evidence: recorded label=... exit=...
log=...` summary lines — each carries the lane's exit code and a per-run log
file (no shared /tmp collisions between concurrent ships). Read the log files
for failure detail.

**If any test fails:** Do NOT immediately stop. Apply the Test Failure Ownership Triage:

{{TEST_FAILURE_TRIAGE}}

**After triage:** If any in-branch failures remain unfixed, **STOP**. Do not proceed. If all failures were pre-existing and handled (fixed, TODOed, assigned, or skipped), continue to Step 6.

**If all pass:** Continue silently — just note the counts briefly.

## Step 6: Eval Suites (conditional)

Evals are mandatory when prompt-related files change. Select from the full diff,
including uncommitted changes, before deciding whether to skip.

**1. Select affected suites using the project's contract.**

**Project-native path:** Read CLAUDE.md/AGENTS.md, package scripts and the eval
dependency map. Include changed prompts, skill templates, judges and harness
code. Use the documented selector and pre-merge command. If it reports no
affected suites, record that result and continue to Step 7. If prompt-related
files changed but selection or the command is unknown, report the validation
gap and ask before shipping. A missing Rails-pattern match is not a skip signal
for another stack.

**Rails example only — when this repository provides `bin/test-lane` and
`test/evals/*_eval_runner.rb`:**

- Match the diff against the project's documented prompt paths, such as
  `app/services/*_prompt_builder.rb`, generation/writer/designer services,
  evaluator/scorer/classifier/analyzer services, voice/writing/prompt/token
  concerns, chat tools, `config/system_prompts/*.txt` and `test/evals/**/*`.
- Match changed files to each runner's `PROMPT_SOURCE_FILES`; follow shared
  judge/support/fixture imports to all affected suites. A runner such as
  `post_generation_eval_runner.rb` maps to `post_generation_eval_test.rb`.
- Use the project's full pre-merge tier (`EVAL_JUDGE_TIER=full` for this runner).
  Do not substitute a cheaper development tier. If selection remains uncertain,
  include every plausibly affected suite.

**2. Run the selected command and preserve its exit status.**

For the Rails example:

```bash
set -o pipefail
EVAL_JUDGE_TIER=full EVAL_VERBOSE=1 bin/test-lane --eval test/evals/<suite>_eval_test.rb 2>&1 | tee /tmp/ship_evals.txt
```

Use the native command for other stacks. Respect the project's concurrency and
retry policy. Rails suites sharing a test lane run sequentially; stop on the
first failure before starting another paid suite.

**Long eval suites (30+ min): launch detached so a turn boundary can't kill them.**
Use the detached runner and eval lock; set its outer timeout to cover the
project's declared suite duration and retries. Do not change individual eval
limits. For a suite whose full bound fits 5400 seconds:

```bash
~/.claude/skills/gstack/bin/gstack-detach --label ship-evals --lock gstack-evals --timeout 5400 -- <project eval command>
```

Poll the printed log for `### gstack-detach EXIT=<code> ###`. Silence is not
success. Retain every configured attempt; skipped or unstarted cases do not
satisfy coverage.

**3. Check results and save evidence for Step 19.**

- **If any eval fails:** Show failures and available costs, then **STOP**.
- **If all selected evals pass:** Record actual counts, any reused evidence and
  its source, and available costs. Continue to Step 7.
