bvandeusenandClaude Fable 5 7d48eb0b1b refactor(services): one periodic-task shape, one APScheduler job shape, one token hash, one summary rule — the services pass of the shape audit (#2830, milestone 296)

- background.start_periodic(interval, work, label=) replaces the three hand-rolled
  while-True/sleep/try loops in logging, auth and notifications.
- services/scheduler.ScheduledJob replaces the four private BackgroundScheduler
  copies in recurrence/version_pinning/trash/db_maintenance schedulers; public
  start_/stop_/reschedule_ surfaces unchanged.
- api_keys.hash_token is the one sha256 helper; auth.py used to inline it 5x.
- auth.is_registration_open reads via settings.get_admin_setting; notification
  prefs read via settings.get_setting; _fire_share_email uses _get_user_email.
- projects.get_project_summary / milestones.get_project_milestone_summary are
  now the one-id view of their batch siblings instead of a second copy of the
  queries; sharing.best_permission_by (was _deduplicate_by_permission) is the
  one rank-dedup, now also used by list_projects_for_user.
- backup: the row builders for every section both exporters carry are named
  functions, so a column added to one export cannot silently miss the other.
- iso() from models.base replaces the attr.isoformat()-if-attr-else-None idiom
  and db_maintenance._iso across services; backup keeps its explicit shape.
- trash.py hoists the sql_delete/timedelta imports it re-imported per function.

bvandeusenandClaude Opus 5 be3a0ffaf9 fix(projects): batch the summary queries — the fan-out was exhausting the pool

Reported live: Projects and Snippets showed skeletons that never resolved,
/knowledge worked intermittently. The logs named it exactly:

    QueuePool limit of size 5 overflow 10 reached, connection timed out, 30.00
    GET /api/settings  500  30584.0ms
    GET /api/projects  200  30882.9ms

/api/projects was not hanging — it was waiting out the 30-second checkout
timeout and then returning 200 with summaries silently missing, because
_attach swallowed the TimeoutError. Nobody waits 31 seconds, so it read as a
hang.

THE SHAPE: routes/projects.py ran asyncio.gather over every project. Each
_attach called get_project_summary, which opened its own session for three
queries and then called get_project_milestone_summary — which opened one more
session PER MILESTONE. So 25 projects asked for roughly 250 concurrent
checkouts against a pool of 15 (SQLAlchemy's default 5 + 10 overflow).

That is why unrelated routes failed too. Snippets and /knowledge were never
broken; they queued behind the burst and inherited its timeout. /api/settings
returning 500 while /api/projects returned 200 is the same cause wearing two
faces.

The comment above the gather said "one backend pass instead of N+1 frontend
calls". It did remove the N+1 from the network — and recreated it against the
connection pool, where it is worse, because the browser had at least been
serialising those calls.

Now: get_project_summaries() does all projects in four queries and one session,
and get_project_milestone_summaries() does all milestones in two. Two sessions
total for the whole page, independent of how many projects exist.

The progress calculation is extracted to _progress_from_counts and shared by
both the batch and single paths, so the cancelled-exclusion rule cannot drift
into two versions that disagree about whether a milestone is finished.

Tests assert the SESSION COUNT, not just the values. An implementation that
returned identical output while opening a session per project would pass a
correctness test and reproduce the outage.

Deliberately NOT done: raising pool_size. It would move the cliff rather than
remove it, and this endpoint now needs two connections regardless of scale.

Closes #2384.

bvandeusenandClaude Opus 4.8 1f6c592226 feat(plans): milestone-as-plan-container; retire kind=plan (T3)
CI & Build / TypeScript typecheck (push) Successful in 22s

The milestone becomes the plan container: a new nullable milestones.body
holds the design/intent (Goal/Approach/Verification) and individual steps
live as first-class child tasks (milestone_id) instead of checkboxes crammed
into one kind=plan task body. start_planning now creates a MILESTONE seeded
with the body template (not a kind=plan task) and returns it with applicable
rules; a new get_milestone MCP tool reads the plan back (body + steps + rules).

kind=plan is hard-retired going forward — start_planning never creates one.
The 'plan' task_kind enum value stays valid so the 11 historical plan-tasks
remain readable in place; no body-shredding backfill (corpus review showed
auto-splitting their checklists into tasks would be lossy: embedded code
blocks, a non-binary [~] state, tables, ID-encoded hierarchy).

- migration 0066: add milestones.body
- model/service/route/MCP: body passthrough on create+update; get_milestone
- server _INSTRUCTIONS: "plan" = milestone w/ body + child step-tasks
- UI: ProjectView shows/edits a milestone's plan body; start_planning expands
  the new milestone and opens its plan editor
- tests updated to the milestone contract + new body/get_milestone coverage

bvandeusenandClaude Opus 4.8 b255a0f90e refactor: rename package fabledassistant -> scribe (code-only)
CI & Build / Python lint (push) Successful in 3s
CI & Build / TypeScript typecheck (push) Successful in 35s
CI & Build / Python tests (push) Successful in 54s
CI & Build / Build & push image (push) Successful in 1m14s
Renames src/fabledassistant -> src/scribe and all imports, plus the
default DB name and DB user/password (fabled -> scribe) in config +
compose. 952 refs / 154 files. Reverses the old 'internal name stays
fabledassistant' convention.

Code-only: live databases are still physically named 'fabledassistant'.
Deployed environments must set POSTGRES_DB / POSTGRES_USER (or rename the
DB) since the defaults now resolve to 'scribe'. Repo (FabledScribe), git
host (fabledsword), MCP (fabled-git) and the image name (fabledscribe)
are intentionally unchanged.

ruff check src/ clean locally; CI (typecheck + pytest) is the gate.
