Task 1.5 — Event-participation collections
Five collections + 10 relations + 5 composite unique constraints,
captured into snapshots/schema.yaml (now 105 KB, up from 53 KB).
Collections:
- events — 11 fields incl. organization_id M2O, discipline enum
(rally / time-trial / regatta / trail-run / hike),
starts_at/ends_at required.
- classes — 8 fields incl. event_id M2O, code unique within event.
- entries — 11 fields incl. event_id/vehicle_id (nullable for foot
races) /class_id M2O, race_number, status enum with
8 lifecycle values, archive on `withdrawn`.
team_id deliberately omitted (Phase 2+).
- entry_crew — junction with role enum
(pilot/co-pilot/navigator/mechanic/rider/runner/hiker).
- entry_devices — junction with optional assigned_user_id (panic button
body-wear); ON DELETE SET NULL on that field since
user removal shouldn't block the device record.
10 M2O relations wired, all ON DELETE RESTRICT except
entry_devices.assigned_user_id (SET NULL).
db-init/005_event_participation_unique_constraints.sql adds composite
UNIQUE on:
events (organization_id, slug)
classes (event_id, code)
entries (event_id, race_number)
entry_crew (entry_id, user_id)
entry_devices (entry_id, device_id)

Destructive-apply incident (recovered):
First attempt at this task hit a real foot-gun. After creating the 5
collections via MCP, we ran `compose build && up -d`. The image rebuild
baked in the snapshot from task 1.4 (only 7 collections). Boot's
schema-apply step ran `directus schema apply --yes` against that stale
snapshot — saw the 5 new collections in the DB but not in the snapshot
— DELETED THEM, taking the constraints with them.
Recovery: re-created the 5 collections + 10 relations via MCP, ran the
ALTER TABLE statements directly via psql to restore the constraints,
ran schema:snapshot BEFORE any further restart so the YAML reflects
the live state. Documented the operator rule (never rebuild with
uncommitted schema changes) inline in the task spec and in the
directus wiki entity page (separate commit in trm/docs).
Phase 3 hardening on the radar: DIRECTUS_SCHEMA_APPLY_MODE env var
with auto/dry-run/skip modes so dev environments default to non-
destructive behavior.
ROADMAP marks 1.5 done. Phase 1 progress: 7/9 tasks complete (1.1–1.7);
1.8, 1.9 remain.

Task 1.4 — Org-level catalog collections
Seven collections + 3 directus_users custom fields, captured as
snapshots/schema.yaml (53 KB, 2,159 lines).
Collections:
- organizations — UUID PK, name, slug UNIQUE
- vehicles — UUID PK, make/model required, year/cc/vin/plate optional
- devices — UUID PK, imei UNIQUE, model required
- organization_users — junction with role enum (org-admin, race-director,
marshal, timekeeper, participant, viewer)
- organization_vehicles — junction with registered_at
- organization_devices — junction with registered_at
- directus_users — extended with phone, birth_date, nationality
Six M2O relations on the junctions, all ON DELETE RESTRICT (matching
the schema-draft decision: deletion of an org/vehicle/device/user
requires explicit cleanup of dependents).
db-init/004_junction_unique_constraints.sql adds the composite UNIQUE
constraints on the three junctions:
organization_users (organization_id, user_id)
organization_vehicles (organization_id, vehicle_id)
organization_devices (organization_id, device_id)
Composite uniqueness lives in db-init rather than the Directus snapshot
because Directus's snapshot YAML format only captures single-column
unique constraints (the field-level is_unique flag). The migration file
documents the split inline.
Driven via the directus-local MCP server rather than admin-UI clicking
— programmatic create-collection/create-field/create-relation calls
against the running Directus instance, then `pnpm run schema:snapshot`
to capture the canonical YAML.
Live-verified: db-init/004 applies cleanly on container restart
(0 rows in the empty junctions, no constraint violations); schema-apply
against a snapshot-empty boot still skips correctly; all seven new
collections show up in the admin UI's data model navigation.
Snapshot includes positions and migrations_applied as auto-discovered
ghost entries (Directus introspects all public-schema tables). Harmless
— db-init creates them before schema-apply runs, so snapshot apply just
finds them already present.
ROADMAP marks 1.4 done. Phase 1 progress: 6/9 tasks complete (1.1, 1.2,
1.3, 1.4, 1.6, 1.7); 1.5, 1.8, 1.9 remain.

Task 1.3 — Initial migrations
Three SQL files under db-init/ create the schema processor writes
against. All three apply cleanly via apply-db-init.sh, are idempotent
on re-run, and end with assertion blocks that catch silent
schema drift.
001_extensions.sql — registers timescaledb on the directus database.
PostGIS deferred to Phase 2 (per Plan A). The timescaledb-ha image
pre-creates the extension at DB init, so the IF NOT EXISTS guard
fires as a NOTICE — expected and harmless.
002_positions_hypertable.sql — positions hypertable, exact
column-by-column match against processor/src/db/migrations/0001_positions.sql.
Cross-checking against processor surfaced 8 divergences from the
original task spec; processor wins in every case (it is the writer
and is in production). The corrections:
- added ingested_at timestamptz NOT NULL DEFAULT now()
- added codec text NOT NULL
- altitude/angle/speed: real NOT NULL (not DOUBLE PRECISION nullable)
- satellites/priority: NOT NULL
- removed attributes DEFAULT '{}'::jsonb (processor always writes)
- replaced PRIMARY KEY with UNIQUE INDEX positions_device_ts
(idiomatic for TimescaleDB hypertables)
- chunk interval 1 day, not 7 days
- two indexes (positions_device_ts + positions_ts), not one composite
Without these corrections every processor INSERT would have failed
with NOT NULL violations. Spec deliverables section updated to
reflect the correct shape so future readers see the right schema.
003_faulty_column.sql — adds the operator-controlled faulty boolean
flag plus the partial index positions_faulty_idx ON (device_id,
ts DESC) WHERE faulty = FALSE. The column is set only via Directus
admin (Phase 4 permissions); processor's writer never touches it.
The partial index optimises the hot-path read pattern (every
processor evaluator filters faulty = FALSE); operator queries that
look at faulty rows specifically use the broader positions_device_ts
index from 002.
Live-verified 2026-05-01:
- First apply: 3 applied, 0 skipped, exit 0.
- Re-run: 0 applied, 3 skipped, exit 0.
- All 13 columns present with correct types/nullability/defaults.
- Hypertable registered with 1-day chunk interval.
- Three expected indexes present.
Non-blocking observation: TimescaleDB's create_hypertable()
auto-created a fourth index (positions_ts_idx) duplicating our
explicit positions_ts. Processor's migration has the same redundancy
so stage already lives with this. Cleanup path documented in the
task spec for Phase 3 hardening (create_default_indexes => FALSE
in the create_hypertable call).
ROADMAP marks 1.3 done; 1.4 next.

Task 1.1 — Project scaffold
Phase 1 task 1.1 lands. Directus 11.17.4 boots locally end-to-end against a TimescaleDB+PostGIS container; admin UI serves at :8055, admin bootstrap from env vars works, named volumes preserve data across down/up cycles. Scaffold: - Dockerfile — FROM directus/directus:11.17.4. Pre-installs postgresql16-client (ahead of task 1.2's db-init runner needing psql). Bakes in /directus/snapshots, /directus/db-init, /directus/scripts, /directus/extensions, /directus/entrypoint.sh. - compose.dev.yaml — db (timescale/timescaledb-ha:pg16.6-ts2.17.2-all) + directus (local build), healthchecks, named volumes directus-pg-data + directus-uploads. - entrypoint.sh — placeholder using upstream's actual flow (node cli.js bootstrap && pm2-runtime start ecosystem.config.cjs); the real db-init -> schema apply -> start wrapper lands in task 1.7. - package.json — scripts-only (dev, dev:down, dev:reset, schema:snapshot, schema:apply, db:init), no runtime deps. - .env.example — sectioned, fully documented, KEY/SECRET marked required with generation hints. - .gitignore, .dockerignore — match the processor service conventions. - snapshots/, db-init/, scripts/, extensions/ — empty with .gitkeep, filled by later Phase 1 tasks (1.3, 1.6) and Phase 5. Lessons locked in (against the empirical pnpm dev boot): - timescale/timescaledb-ha:pg16-latest does NOT exist on Docker Hub. Pin a concrete version (we used pg16.6-ts2.17.2-all). - This image's data directory is /home/postgres/pgdata/data, not /pgdata or /var/lib/postgresql/data. PGDATA env var and the volume mount must both target it. - The -all variant bundles PostGIS binaries but the extension is not auto-created on the directus database; CREATE EXTENSION lands in Phase 2 alongside the geofences/SLZs/waypoints collections. - The upstream image's CMD is bootstrap + pm2-runtime, not a simple cli.js start. Bypassing pm2 would lose crash recovery. These corrections folded into 01-project-scaffold.md (deliverable line + Done section), 08-gitea-ci-dryrun.md (CI service tag), and the inline comments in compose.dev.yaml so future implementers don't re-discover them. Status: ROADMAP marks 1.1 done, Phase 1 in progress, 1.2 next. |
