+# Implement plan 32: one-shot chronological section sort
+
+Read approved plan 32 from local planning checkout only when HEAD equals
+`a2557b2ad40e06e1e63eb655f286e6a78fe6bf0d`; otherwise use
+`git show a2557b2ad40e06e1e63eb655f286e6a78fe6bf0d:plans/32-section-date-sorting.md`. Read current `AGENTS.md`, RTK,
+issue/domain guidance, ADRs, and applicable brainstorming/TDD skills. Approved direction fixes behavior; do not ask routine
+interaction questions. Run root Intent inventory and load matching local skill before edits. Do not spawn subagents, touch
+ledger, mutate issues, merge, push, or create PR.
+
+Start clean from refreshed `origin/main`, rename branch `codex/issue-2725-one-shot-sort`, revalidate live issue 2725 and open
+PRs, and run exact drift. Ensure no active owner touches same section menus. Plan 24 is presentation-only; do not stack unless
+current source truly requires its interface. This increment is one-shot Experience/Education only, not autosort or full issue
+closure.
+
+Strict TDD and contract:
+
+- First characterize existing `parsePeriod` for numeric/localized/ongoing/year-only/reversed/blank/bare-Present/prose/equal
+  values without changing parser or ATS behavior. Record nullable cases.
+- Add failing tests for pure `sortSectionItemsByPeriod(items, locale): { items, unresolvedIds }` in `packages/resume` and
+  an intentional public export. New array, original item objects/content/IDs unchanged, identical multiset, no input mutation.
+- Total order: ongoing first by descending start; known-ended by descending end then start; stable ties. Mixed precision uses
+  internal `[year, month ?? 0]`; never persists fabricated dates. Missing known endpoint ranks after known. Unresolved and
+  reversed entries remain stable at end; return their exact IDs. Cover transitivity, determinism/repeat invocation,
+  empty/single, localized months, year-only, bare Present, blank, prose, reversed, and stable equal ranges.
+- Add existing-menu one-shot action only for built-in Experience/Education through one `useUpdateResumeData` draft mutation.
+  One undo restores exact order; save/reload retains chosen order; later edits never resort. Locked state disables action.
+  Concise Lingui notice identifies only affected entries in current section, preferably safe title or ID semantics supported by
+  current notification patterns; do not expose unrelated resume content.
+- No schema setting, persistent autosort, Date.parse, free-text rewrite, role/custom-section sort, or implicit render/save sort.
+
+Record RED and GREEN. Run period/helper tests, focused web menu/undo tests, resume/web typechecks, boundaries, build, Lingui
+catalog checks, and synthetic authenticated persistence E2E if feasible. Use narrow non-writing Biome; disclose/inspect any
+write-capable `pnpm check`. Run diff/scope checks. Commit locally; no push/PR before independent review.
+
+Write `.orchestration/plan-32-implementation.md`: live/drift state, facts vs uncertainty, RED/GREEN, exact commit/files,
+tests/results, skipped gates, risks, partial issue coverage, PR `not created`. Final response at most ten lines.
