-# Personal OS — PostgreSQL Schema
-
-The `personal_os` Postgres database is the durable backbone of Alex's Personal OS. It stores Asana state, agent annotations, file references, wiki content, and semantic memory. Extensions used: `vector` (pgvector) and `pg_trgm`.
-
-## Core tables
-
-### `tasks`
-One row per Asana task GID. Upserted on every sync. Tracks name, notes (text + html), due/start dates, completion state, section, assignee, creator, project, source, timestamps, sync cursors, and raw JSON. Indexed on modified_at, due_on (partial), section, assignee, source, completed, plus a trigram index on name for fuzzy search.
-
-**`source` values** — discovery channel:
-- `my_tasks` — assigned to Alex, in My Tasks sections
-- `following` — Alex is a follower
-- `delegated` — Alex created it, someone else owns
-- `project` — project membership, otherwise uncovered
-
-### `stories`
-Raw Asana event log per task — comments, assignments, due-date changes, etc. `resource_subtype` is Asana's event type. Stores plain and HTML body (HTML retains embedded task references). Indexed on task_gid, created_at, subtype, creator.
-
-### `task_edges`
-Directed graph of inter-task relationships. `relation_type` covers `subtask`, `dependency`, `dependent`, `project_sibling`, `mention`. Primary key `(task_gid, related_gid, relation_type)`.
-
-### `task_annotations`
-Agent or user-written metadata. Types: `irrelevant`, `watching`, `needs_action`, `snoozed`. Includes reasoning note, snooze date, and `annotated_by` (`agent` | `user`).
-
-### `sync_state`
-One row per logical sync stream (`my_tasks`, `following`, `delegated`, `project:{gid}`, `workspace_events`). Holds last sync time, incremental cursor, and last full-sync time.
-
-### `task_embeddings`
-pgvector 1024-dim embeddings (Voyage AI text-embedding-3 dims). HNSW cosine index.
-
-## Convenience view
-
-`active_tasks` — non-completed, non-irrelevant, non-snoozed tasks. Ordered by `source` priority (`my_tasks` → `delegated` → `following` → `project`), then due date, then modified.
-
-## Wiki / memory tables
-
-### `file_references`
-Sources for wiki ingest. Includes a macOS security-scoped `bookmark_data` BYTEA, cached path, optional URL, SHA256 `content_hash`, MIME, title, tags, JSONB `modification_log`, and `wiki_stale` flag that triggers next ingest run. Namespace constrained to `work`/`personal`/`family`.
-
-### `wiki_pages`
-LLM-synthesized markdown (not verbatim copies). Tracks sources JSONB, `confidence` (default 0.8), `superseded_by` chain for versioning, `stale` flag, `last_synced_hash`, and 1536-dim embedding. ivfflat index recommended once row count > 1000. See [[wiki-ingest-process]] for the current file-based replacement that supersedes this table.
-
-### `memory_store`
-Semantic memory from Discord, Claude sessions, manual entries. `type` ∈ `fact|preference|decision|person`. `source` ∈ `discord|claude|manual`. JSONB entities array, confidence, optional `expires_at` for non-permanent facts, 1536-dim embedding.
-
-## Phase 0 additions (2026-04-27)
-
-- `namespace TEXT NOT NULL DEFAULT 'work'` added to all core tables — supports work/personal/family separation.
-- `possibly_deleted BOOLEAN` and `last_seen_in_full_sync TIMESTAMPTZ` added to `tasks` so sync can detect Asana deletions.
-
-## Notes on usage
-
-- Stories are fetched after `tasks.stories_fetched_before` cursor — incremental.
-- `task_annotations` is the only table the agent writes to from inference — `tasks` and `stories` are sync-owned.
-- The `wiki_pages` table is effectively superseded by Obsidian + frontmatter `content_hash` (see [[personal-os-state-2026-04-27]] Decision 8). Schema retained for now.
-
-## Key Points
-- Source-of-truth for Asana state is this DB, not the Asana API at query time.
-- `source` column on `tasks` drives prioritization in `active_tasks` view.
-- `namespace` column enables future Phase 2-family without schema churn.
-- pgvector tables are provisioned but not yet populated — Phase 2 work.
-- File-references / wiki-pages tables exist but Obsidian vault replaced them in practice.

-# Weekly Review — Week of 2026-05-25
-
-## ✅ Moved Forward
-
-**New Top Priority project kicked off and shipping** — [iOS Address onboarding conflicts with unified input and ship AI onboarding winner](https://app.asana.com/0/0/1214592943696234) (due Jun 5). [Kick-off](https://app.asana.com/0/0/1214592851898713) ran async May 26 with Alessandro; scope locked, advisor on board, and four implementation PRs landed in week one:
-- [Ship AI onboarding winner (Treatment B) [0.5d]](https://app.asana.com/0/0/1215009192158955) — PR up
-- [Hide "stop chat" button in the input box [0.5d]](https://app.asana.com/0/0/1215009192158954) — PR up
-- [Hide Free plan • Upgrade in onboarding [0.5d]](https://app.asana.com/0/0/1215009192158952) — PR up, fade-in tweak in review
-- [Disable back button during duck.ai onboarding [1d]](https://app.asana.com/0/0/1215009192158960) — descoped (closed)
-
-**Prior O-N project wrapped** — [iOS: Introduce a new screen that allows usage of the toggle with Search or Duck.ai set as the default toggle state](https://app.asana.com/0/0/1213320237636425) closed May 26. A/B/N experiment concluded with Treatment B as winner. [Postmortem](https://app.asana.com/0/0/1213320327587346) completed.
-
-**Incident closed cleanly** — [Incident Postmortem: AI Agent use via likely external Discord service](https://app.asana.com/0/0/1214996544314182) completed May 28. Action items captured and assigned (GDPR follow-up scheduled, [Mattermost Bots request](https://app.asana.com/0/0/1214799615211686) submitted).
-
-### Ship Reviews closed
-None this week. (Prior week's Ship Review for "Demo tracker blocking" closed May 20.)
-
-### Tech Designs approved
-None this week.
-
-### PRs merged / reviewed
-- [PR: Simplify tab access in TabBarViewController](https://app.asana.com/0/0/1215059168411571) — merged May 28
-- [PR: iOS: Demo tracker blocking after chat in onboarding](https://app.asana.com/0/0/1214425079182350) — testing steps refreshed, dax-logo blink fix landed, ready for review
-- Alessandro's UTI work PR (#4668 in apple-browsers) — approved & merged
-- 3 new PRs opened for current TP project (above)
-
-### Rotations completed
-None active this week.

-
-## 🔄 Didn't Move
-
-Older active/planning items that didn't get a touch — mostly tech-debt / infra that loses out to project work:
-
-- [Drop Storyboards in favor of code-initialized views](https://app.asana.com/0/0/1206472717181420) — active since Feb, no movement. Likely deprioritized in favor of project work; reassess whether it should stay `active`.
-- [UI Tests refinement](https://app.asana.com/0/0/1210056873095697) — active since Feb. Tied to broader test-infra effort; needs a champion or descoping.
-- [GH Workflow Failure - UI Tests](https://app.asana.com/0/0/1213729659282440) — active, last touched Mar 20. Worth a 30-min triage: still failing? Still relevant?
-- [PR Check failing on main: testWhenTabWithConnectionLostErrorActivatedAndReloadFailsAgain](https://app.asana.com/0/0/1213975496167929) — due Apr 22, modified May 13. Either fix or quarantine the test.
-- [Cursor integration: configure VSCode support](https://app.asana.com/0/0/1209808486380252) — active since May 7, no progress. Low-stakes; close or schedule.
-
-Likely cause: TP project work + the AI Agent incident consumed the week. Recommend a Quick-Wins-style sweep on one of these next week if the schedule allows.

-## 🔗 Open Loops Carrying Forward
-
-**Current TP project — live PRs heading into review/ship next week:**

-## 📅 Next Week Setup
-
-**TP Suggestion**: Continue [iOS Address onboarding conflicts with unified input and ship AI onboarding winner](https://app.asana.com/0/0/1214592943696234). Reasoning: project due Jun 5; 3 PRs in review and 3 tasks still to start. Treatment B ship needs to clear Ship Review next week to hold the schedule — and you're partly AFK for WWDC Jun 8–12, so the project must close before then. This is the obvious TP, keep it.
-
-**Rotation**: None starting next week.
-
-**OOO watch** — heads-up on collaborators:
-- **Dominik (career advisor)** AFK Jun 1–3 (LDX3) and Jun 4–5 (public holiday). Effectively gone Mon–Fri. **1:1 likely skips** — confirm reschedule.
-- **Sabrina, Lorenzo, Fernando, Pete, Marcos** all at LDX3 Jun 1–3. Several iOS/macOS folks unavailable early week — anything needing their review should ship today or wait.
-- **You** — [Partly AFK Jun 8–12 for WWDC'26](https://app.asana.com/0/0/1212684797790491). Two weeks out, but the TP project due Jun 5 needs to close before WWDC week.
-
-**1:1 with Dominik** — last agenda was [May 26](https://app.asana.com/0/0/1214933759913756). Next slot likely Jun 9+ given Dominik's OOO. Items to bring:
-- TP project ship status (Treatment B Ship Review, project close-out before WWDC)
-- AI Agent incident postmortem outcomes — Mattermost Bots + Discord GDPR action items
-- DDG Mac runner/AI worker infrastructure (carry-over from last agenda)
-- Pre-WWDC handoff plan for in-flight work
