+# 86 — Journal module
+
+## Goal
+
+Ship a per-user journal module with entries, mood tracking, insights, and journal API endpoints on the existing API foundation.
+
+## Why
+
+P1 personal journaling with mood/stress/pills tracking and stats, without blocking on P2 work.
+
+## Depends on
+
+- 85 (shared rich-text editor)
+- 87 (API surface for existing modules — journal adds endpoints the same way)
+- ADR `0005-journal-research.md` (Gitea #20)
+
+## Scope
+
+- Research ADR 0005 (mood/journal libs; build-vs-adopt).
+- Schema + CRUD (per-user entries).
+- Index: last 5–10 entries compact, browse all, small calendar of days with entries.
+- Entry detail and create: **date (default today) and time (default now) required**; everything else optional.
+- Fields: rich note text (shared editor); numerical stress; mood with color/emoji options and **multi-select**; took-my-pills-today boolean.
+- Module-level mood-tracker view over time.
+- Per-user insights/stats (trends, streaks, correlations — propose specifics in ADR/implementation).
+- Journal API endpoints (additive on 87).
+- Playwright: new `tests/e2e/journal.spec.ts` — minimal entry → recent list → detail → mood tracker loads.
+
+## Out of scope
+
+- Household-shared journals (per-user only).
+- LLM agent tools for journal (88 can add later).
+
+## Acceptance criteria
+
+- [ ] ADR 0005 accepted.
+- [ ] Create entry with only date/time.
+- [ ] Index, detail, mood tracker, and insights views work.
+- [ ] Journal API endpoints documented and callable with token auth.
+- [ ] E2E happy path green.
+
+## Notes
+
+- Gitea epic: [#19](https://gitea.ginnoir.com/ginnoir/famapp/issues/19); children #20–#27
+- Depends on #7 (rich-text) and #15 (API surface)
