Multi-site distribution readiness: settings-driven site config, security closeout, release engineering, v0.5.0
Make the app distributable to other GE Aerospace sites (one self-hosted
instance per site, ADR-004). GE values remain the shipped defaults; every
site-specific behavior is now a Setting an admin can change in the UI.

Settings-driven site config:
- Branding: site/QR/badge logos, favicon, primary color (upload endpoints
  mirror the map-blueprint pattern; new Settings > Branding section).
- ServiceNow: search/incident/change URL templates ({ticket}), ticket
  prefixes, enable toggle. Defaults point at the current
  geaerospaceqa.service-now.com global search. Disabled = plain-text tickets.
- Employee-id regex (employeeid_pattern), printer hostname template,
  QR label targets (qr_target_printer / qr_target_usb, blank = asset page,
  else URL template with placeholders), usb_label_style (barcode|qr).
- West Jefferson floor-plan PNGs removed from the tree; generic placeholder
  ships as the map default and sites upload their own blueprint.

Security closeout:
- dashboarddefaults writes now require admin.
- Collector: generic error messages (no str(exc) leak); API key accepted
  via X-API-Key header only (BREAKING: querystring api_key removed).
- IP-based login rate limiting (AUTH_RATELIMIT_* knobs) atop account lockout.
- Setting.set() creation race fixed (IntegrityError retry).

Release engineering and docs:
- __version__ 0.5.0 (distinct from __contract_version__, ADR-007),
  CHANGELOG.md, Gitea Actions CI config, frontend version aligned.
- One wizard-first install story across README/DEPLOY; new CONFIG.md,
  UPGRADE.md, BACKUP-RESTORE.md; CLAUDE.md and ROADMAP de-staled.
- Dockerfile multi-stage build now bundles the frontend; compose binds
  MySQL to 127.0.0.1; stale database/schema.sql and one-off SQL removed.

Debt and fixes:
- .query.get() -> db.session.get() sweep; datetime.utcnow() removed
  (naive-UTC via timezone-aware now); users.py on authz decorators.
- Fixed 4 stale tests (slides feed shape, shopfloor splitperemployee,
  plugin contract purity) and the USB label page field mapping (both usb
  modes emit the cmmc shape: device_id/device_desc).
- Health endpoint reports the real version.

248 tests pass; naming/style check green; frontend builds; fresh-DB
flask db upgrade + seeds verified; QR targets verified by decoding
rendered codes.

# ADR-007: Product versioning and releases
- **Status:** ACCEPTED
- **Date:** 2026-07-10
- **Deciders:** cproudlock
- **Supersedes:** none
## Context
ADR-002 established semantic versioning for the plugin contract via
`__contract_version__` in `shopdb/__init__.py`. That number answers one
question only: is a given plugin compatible with this platform build. It
says nothing about the state of the product as a whole. A sister site
standing up its own instance needs a different answer: which release am I
running, and what changed since the last one.
Until now the product had no version, no tags, no changelog, and no CI.
ADR-002's pinning model implicitly assumes that a downstream site can
pin a known-good build, but there were no tags to pin to. Adopters had no
release record to read before upgrading, and no automated gate confirming
that a given commit builds and passes tests.
## Decision
The product carries its own release version, separate from the plugin
contract version.
1. **Product version** (`shopdb/__init__.py`): a single `__version__`
constant. This is the version of the shopdb-flask product as a whole.
It follows semantic versioning of the product's user-visible and
operator-visible behavior. It is deliberately NOT part of the
`shopdb.api` contract surface, so it is never re-exported through
`shopdb.api`; exporting it would itself be a contract change under
ADR-002.
2. **Plugin contract version** (`__contract_version__`): unchanged from
ADR-002. It moves only when the plugin contract surface changes, per
the major/minor/patch rules in ADR-002.
The two are distinct series with independent bump rules. They happen to
coincide at `0.5.0` for this release; that is a coincidence of timing,
not a coupling. A product release that changes no contract surface bumps
`__version__` while leaving `__contract_version__` fixed, and vice versa.
3. **Release record** (`CHANGELOG.md`, repo root): the canonical,
human-readable record of what changed in each release, in
Keep-a-Changelog format. Every release has an entry; work in flight
accumulates under `## [Unreleased]`.
4. **Git tags**: each product release is tagged `vX.Y.Z`, where `X.Y.Z`
matches `__version__` at the tagged commit. Tags are what ADR-002's
downstream-pinning model pins to.
5. **Frontend version** (`frontend/package.json`): kept in lock-step with
`__version__` so the shipped single-page app reports the same product
version as the backend that serves it.
### Release procedure
To cut release `X.Y.Z`:
1. Bump `__version__` in `shopdb/__init__.py` to `X.Y.Z`.
2. Bump `version` in `frontend/package.json` to the same `X.Y.Z`.
3. Move the accumulated `## [Unreleased]` notes in `CHANGELOG.md` into a
new `## [X.Y.Z] - YYYY-MM-DD` section, leaving a fresh empty
`## [Unreleased]` above it.
4. If the plugin contract surface changed this release, bump
`__contract_version__` per ADR-002 (independently of `__version__`).
5. Commit, then tag: `git tag -a vX.Y.Z -m "shopdb-flask X.Y.Z"`.
6. Push the commit and the tag.
## Consequences
### Positive
- Adopters have a real release to name in bug reports and a changelog to
read before upgrading.
- ADR-002's pinning story finally has tags to pin to.
- Product and contract can evolve at their own pace without one dragging
the other into a misleading bump.
### Negative / cost
- Two version numbers to keep straight. The comment in
`shopdb/__init__.py` and this ADR exist to keep the distinction clear.
- Release discipline: the changelog and both version constants must be
updated together, or the tagged build misreports itself.
### Neutral
- CI (`.gitea/workflows/ci.yml`) runs the backend tests, the naming/style
gate, and the frontend build on push and PR. It is best-effort: Gitea
Actions availability on the host is unverified, so the workflow is
config-only until a runner is confirmed.
## Alternatives considered
1. **Reuse `__contract_version__` as the product version.** Conflates two
independent concerns; a docs-only or UI-only release would either
falsely bump the contract or leave the product looking unchanged.
Rejected.
2. **Calendar versioning for the product** (e.g. `2026.07.0`). Easy to
bump but poor at signaling breaking operator-facing changes. Rejected
for the same reasons ADR-002 rejected it for the contract.
3. **No product version, rely on git SHAs.** Opaque to adopters and
unpinnable in any human-meaningful way. Rejected.
