julian e22d9d489a Tasks 1.6 + 1.7 — schema tooling + real entrypoint flow
Two parallel tasks landing together. The boot pipeline is now wired
end-to-end: db-init → schema apply → directus bootstrap → pm2-runtime.
Live-verified by booting a fresh compose stack to a serving Directus
admin UI on :8055.

Task 1.6 — snapshot tooling:
- scripts/schema-snapshot.sh — host-side, dev-time. Verifies docker
  is on PATH and the directus compose service is running, runs
  `node /directus/cli.js schema snapshot --yes` inside the container,
  copies the YAML out to ./snapshots/schema.yaml. Used after admin-UI
  schema changes to capture the new state for git commit.
- scripts/schema-apply.sh — image-side, boot-time. Reads
  /directus/snapshots/schema.yaml, runs a dry-run preview, then
  applies. Gracefully skips when the snapshot is absent or whitespace-
  only (Phase 1 first-boot path before tasks 1.4/1.5 produce
  collections). SNAPSHOT_PATH env var override for CI flexibility.
- snapshots/README.md — lifecycle doc; warns against hand-editing.

Task 1.7 — real entrypoint flow:
- entrypoint.sh rewritten from Phase 1.1's placeholder to the
  4-step boot per ROADMAP design rule #3:
    1/4 db-init          → /directus/scripts/apply-db-init.sh
    2/4 schema apply     → /directus/scripts/schema-apply.sh
    3/4 directus bootstrap → node /directus/cli.js bootstrap
    4/4 directus start   → exec pm2-runtime start ecosystem.config.cjs
  set -euo pipefail halts boot on any step's non-zero exit. Each step
  emits a [entrypoint] log marker so an operator reading container
  logs sees which step failed.

Bug found and fixed during live verification:
- Both 1.6 scripts initially called bare `directus schema ...` as if
  the CLI were on PATH. Upstream directus/directus:11.17.4 does NOT
  expose `directus` on PATH — invocation is via `node /directus/cli.js`,
  same pattern as the entrypoint's bootstrap step. Both scripts
  corrected. Also added -T to docker compose exec in schema-snapshot.sh
  so the script works in non-TTY contexts (CI).

Phase 5 follow-up (non-blocking) flagged in 07's Done section: Directus
warns "Collection 'positions' doesn't have a primary key column and
will be ignored". The positions table uses UNIQUE INDEX (device_id, ts)
matching processor's pattern, not a PK constraint. Means positions is
not auto-registered as a Directus collection — fine for Phase 1, but
the operator faulty-flag workflow will need a custom endpoint or
manual collection registration in Phase 5.

ROADMAP marks 1.6 + 1.7 done. Phase 1 progress: 5/9 tasks complete
(1.1, 1.2, 1.3, 1.6, 1.7); 1.4, 1.5, 1.8, 1.9 remain.

# schema-snapshot.sh — TRM directus schema snapshot (host-side, dev-time)
#
# Captures the current Directus schema from the running dev compose stack and
# writes it to ./snapshots/schema.yaml for git commit.
#
# Usage
# Run from the repo root (where compose.dev.yaml lives):
# pnpm run schema:snapshot
# Or directly:
# bash scripts/schema-snapshot.sh
#
# Prerequisites
# - docker CLI must be on PATH.
# - The dev compose stack must be running:
# pnpm run dev (or: docker compose -f compose.dev.yaml up -d)
# - The directus service must be healthy (bootstrapped, not just started).
#
# What it does
# 1. Verifies docker is on PATH.
# 2. Verifies the compose directus service is in a running state.
# 3. Runs `directus schema snapshot --yes /tmp/schema-snapshot.yaml` inside
# the container (the container already has all required env vars for DB
# access).
# 4. Copies the generated file out to ./snapshots/schema.yaml.
# 5. Prints a one-line success log with the file size.
#
# Exit codes
# 0 Snapshot written successfully.
# 1 docker CLI not found, or directus service is not running, or snapshot
# command failed inside the container, or copy failed.
#
# Notes
# - The compose service name is `directus`; the compose file is
# `compose.dev.yaml`, resolved relative to the working directory.
# - Do NOT run this from inside the container — it is a host-side script.
# - Do NOT hand-edit snapshots/schema.yaml. Run this script after making
# schema changes via the Directus admin UI.
#
# Wired into package.json as `schema:snapshot`.
