The docs/superpowers/{specs,plans}/ directory was archived to .archive/
in an earlier session (and .archive/ is gitignored). Every md link
into that path is now a broken reference for anyone consuming the
template fresh.
Stripped:
- ADR-011: **Spec:** header line
- ADR-015: **Spec:** + **Plan:** header lines
- ADR-016: **Spec:** + **Plan:** header lines + footer "Spec —"
bullet (the design rationale is captured in the ADR body itself)
- ADR-017: **Spec:** + **Plan:** header lines
- ADR-018: **Spec:** + **Plan:** header lines
- guides/realtime.md: inline "the full spec" link + footer
[Spec] entry (folded its description into the ADR-016 entry)
- guides/events-and-jobs.md: inline "the full spec" link
- architecture/vertical-feature-spec.md: stale "Deleted" subsection
referencing docs/superpowers/plans/*
Updated:
- glossary.md "PRD" entry: clarified status flow now matches the
shipped pnpm work prd-ship lifecycle (draft -> in-review ->
approved -> shipped); removed the parenthetical pointing at
docs/superpowers/specs/ as a definition of "spec"
- glossary.md "spec" flagged-ambiguity: rewritten to reflect that
durable design lives in ADRs (docs/decisions/adr-NNN-*.md) and
implementation seeds live in PRDs (docs/work/prds/*.prd.md) —
"spec" should be avoided in this template
Preserved (legitimate refs to the SuperPowers plugin, not the dir):
- agent-first-workflow-and-conformance.md mentions of
`superpowers:brainstorming` — these reference the external
plugin skill, not a file in the repo

ADR-011: TDD Foundation
Status: Accepted Date: 2026-05-05 Supersedes: none
Context
The vertical-feature monorepo refactor (ADRs 001-010) established clean architecture with per-feature DI containers but did not enforce TDD as the path of least resistance. Agentic workers were producing code-first commits with tests added later, leading to test theatre and mock/real drift.
Decision
-
New package
@repo/core-testing(tag: tooling) — shared test utilities: defineFactory, defineContractSuite, renderWithProviders, mock-payload helpers, jsdom setup file. Taggedtoolingso any package may depend on it as devDependency without boundary violation. -
Vitest base configs split into node + jsdom with safety defaults (clearMocks, restoreMocks, mockReset, unstubGlobals, sequence.shuffle) and coverage thresholds (80/75/80/80 baseline; 100% in entities + use-cases + controllers).
-
Factories per feature in
src/__factories__/replace inline fixtures. Stable date defaults (2026-01-01) so snapshot diffs reflect SUT behavior only. -
Contract suites per repository interface in
src/__contracts__/run against every implementation (Mock + Payload). Eliminates the class of bug where the mock and the real impl drift apart. -
Tests in core-* packages and apps — composition smoke tests (appRouter, payloadConfig, bind-production, providers).
-
Storybook test-runner — every story executed as a smoke test.
-
CI workflow — typecheck + lint + boundaries + test + build + e2e + storybook on every PR. Coverage uploaded as artifact.
-
Two new docs — tdd-workflow.md (process) + restructured adding-a-feature.md (interleaves tests with impl).
Alternatives considered
- Fixture files instead of factories — rejected. Fixtures rot with schema changes and require manual updates per test.
- One shared test file per impl — rejected. Contract suites give the same coverage in fewer LOC and prevent drift.
- Real Postgres in tests via testcontainers — rejected for unit tests (slow, complex). Repository contract suites + vi.mock('payload') give equivalent confidence in milliseconds.
- Stryker mutation testing — deferred. Coverage thresholds + contract suites get us most of the way; mutation testing is incremental.
Consequences
- New package to maintain (small, mostly stable surface).
- Coverage thresholds may fail builds initially; we add tests to cross threshold as features land.
- Sequence shuffle may surface latent flakes; we fix as found.
- Templates for new features now require writing tests first; this is by design.
Refines
- ADR-006 (boundary tags) — adds @repo/core-testing as a tooling package.
