Validation and QA: what counts as evidence here

This skill defines the evidence bar for claiming work complete, the coverage and quality thresholds that gate merges, the golden regression tests that guard settled battles, and the procedure for adding tests. The one-line thesis: a green check proves spec-satisfaction, not correctness, so every completion claim needs cited evidence and every test needs proof it can fail.

The evidence bar

Never claim "should work". Run the thing, capture the output, cite it. The house discipline comes from Skill(imbue:proof-of-work):

Number every piece of evidence: [E1], [E2], each with the exact command and its captured output.
Map each acceptance criterion to evidence with a verdict: Criterion: [E2] -> PASS or -> FAIL.
Give the overall claim one of three statuses: COMPLETE (all criteria passed), PARTIAL (list blockers), BLOCKED (explain why). A blocked task reported as blocked with evidence is a successful report. A guessed "done" is not.
The final response must not contain "should work", "looks right", or any other unverified confidence phrase.

Verifier integrity: never let the generator judge itself

A passing verifier can mislead two ways (from the prover-verifier research, codified in commit 29081fda, module plugins/imbue/skills/proof-of-work/modules/verifier-integrity.md):

Failure mode	What it looks like
Wrong spec	The check confirms the code matches the spec, not that the spec matches intent
Hollow check	`assert True`, a mock returning the expected value, a stubbed service: all green, all worthless

Rules that follow:

The agent that wrote the code must not be the sole judge of whether the code works. Use an independent check: a fresh subagent, the real test suite, a human, or an end-to-end run the generator cannot influence.
Validate the spec separately from the code. A machine-checked pass against a wrong spec is confident, green, and wrong.
When reviewing a test, ask what change to the code would make it fail. If nothing would, it is not a test.

Iron Law TDD (Constitution rule 3)

CONSTITUTION.md rule 3: no implementation without a failing test first. Scope:

Applies to every code change in plugin Python sources (plugins/*/src/, plugins/*/scripts/, plugins/*/hooks/).
Skill files, agent files, and prose docs are exempt. Their analogue is a structural validation test: every new skill needs a test_skill_<name>.py proving the structure.

A structural validation test asserts observable content in the skill file: required sections exist, the referenced modules exist on disk, tables and examples the skill promises are present. Model on plugins/imbue/tests/unit/skills/test_proof_of_work.py, which checks SKILL.md sections, module files, and enforcement tables. The test must fail if someone deletes the section it guards (see the tautological-test trap below).

Thresholds

Gate	Value	Where defined	Enforced by
Root coverage	`fail_under = 85`	root `pyproject.toml` `[tool.coverage.report]`	root pytest runs
Per-plugin coverage	`coverage_threshold` in `[tool.nightmarket]`, 90 for most plugins, 85 for gauntlet	`plugins/<p>/pyproject.toml`	`scripts/run-plugin-tests.sh` passes `--cov-fail-under` only when the key is set and > 0
Mutation testing	weekly Sunday 00:00 UTC cron mutates only sanctum (the matrix falls back to sanctum when the dispatch input is empty); abstract/imbue/attune run only via manual dispatch with `plugin=all` or a named plugin	`.github/workflows/mutation-testing.yml`	mutmut: exit 0 = no survivors, exit 2 = survivors (allowed), anything else = crash
Critical issues	`max_critical_issues: 3`, `enforce_blocking: true`	`.claude/quality_gates.json`	quality-gate tooling
File size	< 20KB and < 5000 tokens per file	`.claude/quality_gates.json`	advisory (`block_on_violation: false`)
Function length	<= 60 lines, complexity < 12, nesting <= 5, debt ratio < 0.3	`.claude/quality_gates.json`	advisory, except security dimension which blocks

Notes:

The run-plugin-tests.sh awk parser reads coverage_threshold from [tool.nightmarket], never from addopts. Use scripts/fix_coverage_threshold.py to migrate a plugin still using the old location.
The script itself sets no minimum floor for coverage_threshold. If the key is absent, no --cov-fail-under flag is passed at all, so a plugin without the key has no coverage gate in the runner.
imbue's own addopts force --cov=scripts plus term and HTML coverage reports on every run, including single-file runs.

The tautological-test trap

PR review here repeatedly catches tests that assert nothing. Evidence in history: a94240e2 (12 tests of constants tightened to behavioral coverage), f1cbbcf1 (strengthened tautological assertions), 30e58586 (validation-floor regression test), 42f7ce84 (round-trip test replacing a structure-only check). The pattern: a test that restates the code, mocks the unit under test, or asserts a constant equals itself.

The counter-discipline is the revert test, executed by sanctum:validate-pr:

Take the fix the PR claims to make.
Edit the fixed line back to its broken state (working tree must be clean first, or the step is skipped as unsafe).
Run the test that supposedly guards the fix.
The test must FAIL against the reverted code. If it stays green, the test is a dead assertion, not a guard.
Restore the fix.

When writing a new test, apply the same standard preemptively: write the test so it would catch the bug's return, then confirm it fails before the fix lands (that is the Iron Law's RED step).

Golden inventory: regression guards worth knowing

These tests lock in lessons from settled incidents. Do not weaken or delete them without understanding the incident they guard.

Guard	Location	What it locks
py39 datetime alias	`plugins/leyline/tests/test_python39_compat.py`	AST-scans leyline source for `datetime.UTC` (a 3.11+ alias). Hooks run under system Python 3.9, and this alias broke the whole hook import chain three-plus times. Ruff UP017 kept auto-reverting manual fixes, so only this AST invariant test holds the line.
Lazy-import blocker	`plugins/gauntlet/tests/unit/test_challenges.py`	Installs a `sys.meta_path` blocker that raises on any re-import of `anthropic`, proving gauntlet's heavy deps stay lazily imported. Eager imports made every git commit emit hook ModuleNotFoundError.
Hook timeout budget	`plugins/herald/tests/unit/test_double_shot_latte.py` (`test_llm_timeout_fits_within_hook_timeout`)	Asserts `LLM_TIMEOUT_SECONDS` is strictly less than the Stop-hook timeout registered in hooks.json. A timeout above the budget once cost the hook its verdict entirely (full record: night-market-failure-archaeology SB7).
Hook stdin contract	`plugins/abstract/tests/hooks/test_hook_io.py`	Locks the input contract of `shared/hook_io.py`: stdin JSON is primary, legacy `CLAUDE_TOOL_*` env vars are fallback only. Env-reading hooks were once silent no-ops for months (full record: night-market-failure-archaeology SB9).

When you fix an incident of a similar class, add its guard here in the same spirit: an invariant test that fails loudly if the lesson is unlearned.

How to add tests

Layout and isolation

Each plugin owns plugins/<plugin>/tests/ with unit/, integration/ subdirectories and its own conftest.py and pytest config in the plugin's pyproject.toml.
Root pyproject.toml sets norecursedirs = ["plugins/*", ...]. Plugin tests MUST run per-plugin. Running them from the repo root causes ImportPathMismatchError from duplicate module names (the root conftest.py documents this).

Commands

# Single test file (fastest loop)
cd plugins/imbue
uv run pytest tests/unit/test_deferred_capture.py -x -q

# Full suite for one plugin
cd plugins/<plugin>
uv run python -m pytest tests/ --tb=short -q
# or, where the plugin has a Makefile target:
make -C plugins/<plugin> test

# Everything (what `make test` at root does)
./scripts/run-plugin-tests.sh --all

# Only plugins with staged changes
./scripts/run-plugin-tests.sh --changed

# Mutation testing for one plugin, locally
cd plugins/<plugin>
uv run mutmut run --paths-to-mutate=scripts/,src/ --tests-dir=tests/

Markers

Root pytest runs with --strict-markers, so only registered markers are legal. Registered in root pyproject.toml: unit, integration, e2e, slow, network, plugin, skill, hook, command, bdd, benchmark (skip benchmarks in CI with -m "not benchmark").

Checklist for new code

Failing test written and observed RED before implementation (Iron Law).
Test would fail if the fix were reverted (revert-test standard).
Correct marker applied and test placed in unit/ or integration/ accordingly.
Plugin suite passes locally with its coverage flag: uv run python -m pytest tests/ --cov-fail-under=<threshold>.
New skill files have a test_skill_<name>.py structural test.

Failure-mode detection: silent failure in scanners

The most recurrent bug class in this repo is the swallowed error. In scanner-shaped code (anything that walks files and reports findings), the signature is except-continue: a try/except that skips a file on malformed input and reports success on the remainder. The scanner looks healthy while ignoring exactly the inputs most likely to be broken.

The house convention since commit 666171c3 (issue #575): a scanner that cannot process an input emits an ADVISORY finding for it instead of skipping silently. Examples from that commit:

check_hook_modernization.py emits findings on malformed hooks.json, SyntaxError, or OSError instead of dropping the file.
pensive harden/scanner.py appends an ADVISORY finding for unreadable files under --strict.
minister dora_metrics warns and sets a partial flag on malformed tag lines instead of silently classifying the repo Elite.

When reviewing or writing scanner code, grep for the pattern:

rg -n "except .*:\s*$" -A2 plugins/<p>/scripts/ | rg -B1 "continue|pass"

Any hit that discards an error without emitting a finding or an inline "why it is safe to discard" comment violates Constitution rule 10 (errors are not optional).

When NOT to use

Running the suites, lint, release, or publish mechanics: use night-market-operations (command anatomy lives there).
Classifying and gating a change, PR review flow, non-negotiables: use night-market-change-control.
A test is failing and you need triage for a known repo failure mode: use night-market-debugging-playbook.
History of why a guard exists (incident narratives, reverts): use night-market-failure-archaeology.
Setting up pytest config or fixtures for a new plugin: Skill(leyline:pytest-config) has the templates, and Skill(leyline:testing-quality-standards) the anti-pattern catalog.

Exit Criteria

Any completion claim made under this skill cites numbered evidence ([E1]...) with commands and captured output, and carries a COMPLETE, PARTIAL, or BLOCKED status.
Every new test added in the session fails when its guarded fix is reverted (demonstrated, not assumed).
New plugin Python code landed with a test observed failing first, and the plugin suite passes at or above its [tool.nightmarket] coverage_threshold.
Any new skill file has a passing test_skill_<name>.py structural test.

### Markers

Root pytest runs with `--strict-markers`, so only registered markers

`benchmark` (skip benchmarks in CI with `-m "not benchmark"`).

### Checklist for new code

- [ ] Failing test written and observed RED before implementation
  (Iron Law).
- [ ] Test would fail if the fix were reverted (revert-test standard).
