--- issue: 559 issue_title: "pi-permission-system: complete the authority/ directory migration" --- # Retro: #559 — pi-permission-system: complete the authority/ directory migration ## Stage: Planning (2026-07-09T00:00:00Z) ### Session summary Planned Phase 9 Step 5: relocating the five remaining escalation/forwarding/subagent modules (`permission-dialog.ts`, `subagent-registry.ts`, `subagent-lifecycle-events.ts`, `permission-forwarding.ts`, `forwarding-manager.ts`) from the flat `src/` root into `src/authority/`, mirroring their test files into `test/authority/`. This is a behavior-preserving mechanical move — the operator's own issue, unambiguous — so the `ask_user` gate was skipped. Plan committed at `packages/pi-permission-system/docs/plans/0559-complete-authority-migration.md`; recommends a single atomic `refactor:` commit (ship independently, hidden changelog type). ### Observations - The root `eslint.config.js` `local-rules/no-parent-relative-imports` rule flags only `../` imports and auto-fixes them to `#src/`/`#test/` aliases; same-directory `./sibling` imports are permitted, which is why the moved modules and `index.ts` use `./`. So `eslint --fix` + `tsc` mechanically enforce most of the import rewrites — the plan leans on the green suite as the full correctness proof. - Import-rewrite rules split into six categories (Design Overview): the subtlety is that `#src/` aliases are package-root-absolute, so an importer's specifier changes because the *target* moved, not because the importer moved; whereas same-dir `./` refs among the five co-moving modules stay put. - Decided to move the five test files into `test/authority/` to match the established `src/authority/foo.ts` ↔ `test/authority/foo.test.ts` convention from Steps 1–4 — the issue only names src modules, but the mirror is the standing pattern. - Explicitly excluded `docs/architecture/v3-architecture.md`: it is a frozen pre-`authority/` snapshot (last touched at #314, no `authority/` subtree at all), so patching two stale tree lines would leave it internally inconsistent. Left as a historical artifact. - Current-state doc grep surfaced three files to update alongside the move: `architecture.md` (tree + Step 5 `✅` + Mermaid node), `subagent-integration.md` (2 prose paths), and the `package-pi-permission-system` SKILL (2 prose paths). Remaining hits are frozen plans/retros/history. - Folded the doc updates into the `refactor:` commit rather than a separate `docs:` commit — a `docs:` commit touching `docs/architecture/` is an unhidden changelog type here and would cut an unwanted release; the package skill also wants the roadmap step-complete marker in the implementation commit. - No follow-up issues filed — scope is fully mechanical with no deferred work. ## Stage: Implementation — Build (2026-07-09T00:00:00Z) ### Session summary Executed the single-step plan in one atomic commit (`c6c84ca7`): `git mv`d the five modules (`permission-dialog.ts`, `subagent-registry.ts`, `subagent-lifecycle-events.ts`, `permission-forwarding.ts`, `forwarding-manager.ts`) and their five test files into `src/authority/` / `test/authority/`, rewrote every import per the plan's six categorized rules, and folded in the architecture-doc, `subagent-integration.md`, and SKILL.md updates. `tsc`, `eslint`, the full suite (2310 tests), and `pnpm fallow dead-code` all passed after the move; pre-completion review returned PASS. ### Observations - The plan's Design Overview correctly predicted all internal import rewrites for the five moved files (categories 1–3), but its Module-Level Changes importer enumeration (category 4/5) missed three root-level files with same-directory `./` imports of the moved modules: `src/permission-gate.ts` (`./permission-dialog`), `src/session-approval.ts` (`./permission-forwarding`), and `src/permission-session.ts` (`./forwarding-manager`). `tsc` caught all three immediately (`Cannot find module`) since they weren't in the `#src/permission-dialog`-style grep the plan ran — a same-dir `./` import to a module that later moves out of the directory has no `#src/` marker to grep for. Fixed inline as part of the same commit; not a plan deviation requiring a stop, since `tsc` made the gap immediately visible and mechanical to close. - Deliberately left the Phase 9 phase-level archival (History table row, new `docs/architecture/history/phase-9-*.md` file, condensed phase summary paragraph matching the Phase 1–8 convention) out of scope, even though all five Phase 9 steps are now `✅`. The plan's Non-Goals explicitly excluded `docs/architecture/history/*`, and that archival is a substantially larger, separate task (a new summary doc) that wasn't reviewed at planning time. Marked only the Step 5 heading, `Landed:` line, and Mermaid node per the plan's explicit scope. - Reviewer verdict: **PASS** — no warnings. Confirmed pure move (import-specifier-only diffs), correct tree-connector glyphs, both invariant-pinning tests (Step 3 forwarded-broadcast, Step 4 grant-scope) still exercised. - No steps remain; ready for `/ship-issue`. ## Stage: Final Retrospective (2026-07-09T20:42:26Z) ### Session summary Phase 9 Step 5 shipped end-to-end in one session (plan → build → ship): relocated the five remaining escalation/forwarding/subagent modules into `src/authority/`, mirrored their tests into `test/authority/`, and closed out Phase 9 (all five steps now `✅`). One atomic `refactor:` commit (`c6c84ca7`), 2310 tests green, `fallow` clean, pre-completion reviewer PASS, CI green, issue closed — no release cut (hidden changelog type auto-batches). ### Observations #### What went well - Tight verification cadence caught the one enumeration gap at zero cost: `tsc` ran immediately after the bulk import rewrite and flagged the three missed root-level importers (`permission-gate.ts`, `session-approval.ts`, `permission-session.ts`) before any commit, so the fix folded into the same atomic commit with no rework or follow-up. - Clean mechanical execution on a 40-file move: `git mv` preserved rename detection (R097–R100 similarity), `biome check --write` auto-sorted the reordered imports, and the whole change verified green in one pass. - Scope discipline at two decision points — declined the Phase 9 phase-level archival (History table + `history/phase-9-*.md`) as out-of-plan-scope, and folded doc updates into the `refactor:` commit rather than a stray `docs:` commit that would have cut an unwanted release. #### What caused friction (agent side) - `missing-context` (planning) — the plan's importer enumeration grepped only `#src/` alias imports and missed three root-level files that imported the moving modules via same-directory `./` specifiers. A same-dir `./` import to a module that *leaves* the directory has no `#src/` marker to match, so the planning grep structurally could not see them. Self-identified via `tsc` at build time. Impact: three extra one-line edits inside the same commit; no rework, no follow-up commit — added friction but effectively zero cost because `tsc` is a perfect net for this class. - `other` (tooling) — the bulk `sed` import rewrite took three attempts: first a `#`-delimiter clash with the `#src/` literal, then a zsh word-splitting trap where an unquoted multiline `$files` list became one "File name too long" argument. Resolved with `| while IFS= read -r f`. Impact: two wasted tool calls; no effect on the committed result. #### What caused friction (user side) - None — the operator ran the three stages via slash commands with no mid-session correction; the work was mechanical and unambiguous, so mechanical oversight was appropriate. ### Diagnostic details - **Model-performance correlation** — the sole subagent dispatch (`pre-completion-reviewer`) ran on `anthropic/claude-sonnet-5`; appropriate for the judgment-heavy review checklist. No mismatch. - **Escalation-delay tracking** — the `sed` tooling friction was three consecutive attempts on the same operation, under the five-call threshold; no subagent escalation warranted. - **Feedback-loop gap analysis** — verification was incremental, not end-loaded: `tsc` after the import rewrites (caught the gap), `lint` + `biome --write` after, full `test` + `fallow` before the commit. No gap. ### Changes made 1. `.pi/prompts/plan-issue.md` — added a Module-Level Changes line: when a plan step moves a module to a different directory, grep same-directory `./` importers too, not only `#src/` alias imports (an alias-only grep structurally misses same-dir `./` callers of a module leaving the directory).
