# Side-Effects Review — PR-REVIEW-HARDENING spec + convergence reports (docs-only)

**Version / slug:** `pr-gate-phase-a-spec-and-reports-docs-only`
**Date:** `2026-04-17`
**Author:** `Echo (instar-developing agent)`
**Second-pass reviewer:** `not required — documentation-only, no runtime surface`

## Summary of the change

Lands the approved, review-converged `docs/specs/PR-REVIEW-HARDENING-SPEC.md` plus its convergence report and per-iteration review artifacts into git. These are the documents the 8 source commits in Phase A implement against; they have no runtime consumer. The spec carries `review-convergence: true` (5 iterations) and `approved: true` (by JKHeadley, 2026-04-17).

Files added:
- `docs/specs/PR-REVIEW-HARDENING-SPEC.md` — the approved spec (~40KB).
- `docs/specs/reports/pr-review-hardening-convergence.md` — ELI10 convergence report.
- `docs/specs/reports/pr-review-hardening-iter3.md` — iter3 findings catalog.
- `docs/specs/reports/pr-review-hardening-iter4.md` — iter4 findings catalog.
- `docs/specs/reports/pr-review-hardening-iter5-interim.md` — iter5 interim status.

## Decision-point inventory

- **None.** Documentation only.

## 1-7. Side-effect review

No runtime surface. No block/allow. No external surface (markdown files in a docs directory). Over-block / under-block / level-of-abstraction / signal-vs-authority / interactions / external surfaces / rollback cost all N/A — `git revert` deletes the files and no agent state depends on them.

## Conclusion

Documentation-only. Adds the authoritative spec + convergence reports to git so subsequent Phase B/C/D commits can reference them by repo-resident path. Clear to ship.

## Evidence pointers

- Spec: `docs/specs/PR-REVIEW-HARDENING-SPEC.md` — 579 lines, review-convergence: true, approved: true (2026-04-17).
- Reports: `docs/specs/reports/pr-review-hardening-convergence.md` + 3 iter reports.
