Owner

Think had runtime architecture rules but no shared standard for deciding whether test evidence supports a claim. This adopts 19 testing principles for Think's capture, read, repair, adapter, CLI/MCP, and macOS boundaries, and makes them required reading in AGENTS.md.

The PR template now asks for change kind, contract/oracle, validation, failure calibration, and remaining gaps. The standard includes the actual command/CI map and an initial risk map. A focused backlog card tracks missing enforcement and links existing startup/latency work. Review requirements apply to new/touched tests immediately; resource sandboxing, automated size/budget checks, quarantine/XFAIL tooling, and continuous fuzzing are explicitly future work.

Change kind: documentation / process. No runtime code, dependency versions, test expectations, or assertions changed. Command and boundary claims were checked against package.json, CI, fixtures, and the infrastructure doctrine; mutation/red-on-parent evidence is not applicable.

Validation:

  • npm run test:fast passed: lint, runtime/hexagonal ratchets, and 185 ports tests (zero failed/skipped) on Node 26.0.0. The ordinary pre-push hook passed independently.
  • Local Markdown links checked (12 resolved); all 19 principles reviewed; git diff --check passed.
  • GitHub Node 22 lint, 185 ports tests, 135 acceptance tests, and stable ci check passed at 6841bad (zero failures; three pre-existing acceptance TODOs): https://github.com/flyingrobots/think/actions/runs/34168720056.
  • Swift and benchmark campaigns were not run locally because no affected behavior changed.

Existing dependency alerts remain outside this documentation change: npm ci reported eight advisories in the unchanged lockfile, and GitHub reported 50 default-branch alerts during push. Neither this PR nor a green test run establishes dependency/release readiness.

The three existing acceptance TODOs concern raw-entry immutability after derived writes, unchanged stored raw bytes after later writes, and explicit entry-kind separation. They remain visible coverage gaps; this policy PR neither fills them nor counts them as passing evidence.

Review Change Stack

Summary by CodeRabbit

  • Documentation

    • Added comprehensive testing standards covering test design, evidence, determinism, resource ownership, regression checks, fuzzing, concurrency, fault injection, and performance validation.
    • Documented current testing commands, CI boundaries, risk areas, review order, and known enforcement limitations.
    • Updated contributor guidance with testing-standard references and end-of-turn evidence requirements.
    • Added a backlog item outlining future work to automate testing-standard enforcement.
  • Chores

    • Enhanced the pull request template with change-kind and test-evidence guidance while retaining the existing test-plan checklist.

Walkthrough

The change adds a repository testing standard, documents test commands and evidence requirements, updates agent and PR workflows, and records a backlog plan for executable enforcement.

Changes

Testing standards and evidence workflow

Layer / File(s) Summary
Testing scope and evidence rules
docs/TESTING_STANDARDS.md
Defines adoption scope, test commands, boundary testing, outcome observation, oracle naming, determinism, and calibration evidence.
Resource, failure, and quality rules
docs/TESTING_STANDARDS.md
Defines resource ownership, size and timeout classification, failure preservation, regression observation, fuzzing, concurrency, fault injection, performance experiments, maintenance, and gating.
PR and agent evidence workflow
docs/TESTING_STANDARDS.md, .github/PULL_REQUEST_TEMPLATE.md, AGENTS.md
Adds a risk map and PR evidence review order. The PR template requests change kind and test evidence. Agent guidance requires standards review and evidence accounting.
Executable enforcement plan
docs/method/backlog/bad-code/CORE_testing-standard-enforcement.md
Documents six implementation slices and completion evidence for testing-standard enforcement.

Estimated code review effort: 2 (Simple) | ~15 minutes

Merge Risk: 🟡 Moderate · up to 6841b

This documentation change establishes testing-evidence expectations, but its PR template can accept incomplete exceptions without recording the affected claim, attempted evidence, remaining risk, or timely review. Update the template before merging so waivers provide the intended accountability.

No change required for the test:fast row.

npm run lint runs ESLint plus both ratchets. The default pre-push path runs npm run test:fast; THINK_PRE_PUSH_FULL=1 selects the full suite instead.

Require the complete exception record.

Line 25 requests an issue or backlog item, an owner, a review date, and an approving maintainer. It omits the affected claim, reason, evidence attempted, and remaining risk. It also omits the rule that the review date is at most 30 days unless a maintainer records a longer interval. A waiver can pass this template without the evidence required by docs/TESTING_STANDARDS.md.

Proposed wording
-- Remaining gaps / exceptions: issue or backlog, named owner, review date, and approving maintainer when a waiver is needed:
+- Remaining gaps / exceptions: affected claim, reason, evidence attempted, remaining risk, issue or backlog link, named owner, review date, and approving maintainer when a waiver is needed. Review dates are at most 30 days away unless a maintainer records why a longer interval is necessary:

As per coding guidelines, docs/TESTING_STANDARDS.md is the mandatory reference for testing evidence and exception disclosure; its supplied contract requires these exception fields.

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
