# Retro: #80 — Extract PermissionPrompter class to unify prompt/log/forwarding chain

## Final Retrospective (2026-05-05T01:20:00Z)

### Session summary

Planned, implemented, and shipped `PermissionPrompter` — a class encapsulating yolo-mode, review logging, and UI/forwarding branching behind a single `prompt()` method.
Released as v4.4.0.
Also performed a thorough gap analysis of `docs/architecture/target-architecture.md` vs. current state, filed #81 and #82 for remaining structural debt, and updated the target doc to reflect all completed work through #66.

### Observations

#### What went well

- TDD execution was clean: 17 new tests, one minor assertion fix (`expect.anything()` vs `undefined`), no rework on the class itself.
- The target-architecture gap analysis was high-value — identified 3 untracked gaps, filed focused issues, and produced a comprehensive doc update accepted without revision.
- Pragmatic commit bundling (test + impl in one commit due to pre-commit hooks) was handled without friction.

#### What caused friction (agent side)

1. `missing-context` — Edited `docs/architecture/v3-architecture.md` without reading its purpose statement ("as-is design" = historical snapshot).
   User had to correct me.
   Impact: 2 wasted commits (`94be5b5`, `c49523e` revert).
2. `wrong-abstraction` — After the v3 correction, added `permission-prompter.ts` to `target-architecture.md` with an "interim; subsumed by permission-gate.ts" annotation.
   The user clarified that interim stepping stones don't belong in the target at all.
   Impact: 2 more wasted commits (`c5cf101`, `f300f08` removal).
   Combined with (1), produced 4 net-zero commits.

   Both were **user-caught**.
   The underlying failure: treating architecture docs as "track current state" rather than understanding each doc's distinct role (historical snapshot vs. aspirational target vs. per-module current description).

#### What caused friction (user side)

- The user could have proactively mentioned "don't touch v3, it's frozen" when asking about `target-architecture.md`.
  However, the doc's own opening line makes its role clear — the agent should have read it first.

### Changes made

1. Added `## Architecture docs` section to `AGENTS.md` distinguishing `v3-architecture.md` (historical, frozen), `target-architecture.md` (living target), and per-module notes (current implementation).
