## [Unreleased]

### Added

- Applications accept an uploaded image and an uploaded installer, rather than
  only a path typed into a text box. The path field kept working only while
  someone maintained a share by hand, and a link to a file nobody could still
  find was indistinguishable from a link to one that worked. The installer
  download is gated on `applications.view` because it is licensed vendor
  software; the image is public, since tiles render before login.
- Warranty records accept an uploaded proof document - the invoice or
  certificate that actually settles a claim. The documentation path stays as it
  was: it points at a vendor portal or a share, which an upload cannot replace.
  Downloads require `warranty.view`, since a proof carries pricing and a service
  tag, and it comes back under the vendor's own filename so it is recognisable
  in a support ticket.
- Toner forecast report: days until each cartridge runs out, soonest first,
  from Zabbix level history. Ordering by days left rather than by level is the
  point - a cartridge at 60% draining fast needs ordering before one sitting at
  8% that has not moved in a month. It also counts how many cartridges each
  printer has been through in the window, which is the number a purchasing
  conversation asks for. Printers with no honest estimate are listed
  separately with the reason (too little history, gauge has not moved, replaced
  recently) instead of being sorted in as zero or as safe, and an unreachable
  Zabbix says so rather than rendering an empty table that reads as "nothing is
  due".
- Fiscal week under the site name in the sidebar and on the shop-floor board,
  as the classic ASP site showed it. People quote a week number across both
  sites, so the arithmetic is a port of the old one (ISO 8601: week 1 contains
  4 January, the week's Thursday decides the year) rather than a fresh
  interpretation.

- Backup history distinguishes CAPTURED from LAST VERIFIED. Captured is when a
  configuration was written; verified is when a PC last posted it and the hash
  still matched. They differ by design, because an unchanged config writes no
  new revision - so a machine checked daily for a year shows one revision from
  last spring, and previously read as abandoned. Shown on the history page and
  on the asset panel; only the current revision carries it, since an older one
  is not what the PC holds now.
- A backup now records that it was CHECKED, not only that it changed. Dedup
  means an unchanged configuration writes no revision, so the stored timestamps
  moved only on a change: a machine whose settings had been stable for six
  months was indistinguishable from a machine whose backup died six months ago.
  The only evidence a backup still ran was a line in a log file on the PC.
  `lastseenat` is touched on every matching post, including the no-op, and is
  backfilled from the timestamps that already exist.
- The low-supplies report lists only the cartridges that need replacing. A
  printer with one empty black and three full colour cartridges was listing all
  four, so the reader had to hunt for the problem inside the row. The report
  exists to answer "what needs replacing".
- Dashboard cards for enforcement failures, machine numbers claimed by two PCs,
  PCs not reporting, backups that have stopped, printer supplies, expiring
  warranties, machines out of service, and the notifications currently showing
  on the floor. The dashboard now renders cards plugins declare, which it never
  did before - five plugins had been declaring widgets into a void, pointing at
  components nobody wrote. Cards are ordered by severity, hide themselves when
  there is nothing to report, gate on a permission, and each fetches
  independently so one broken endpoint cannot blank the board.

## [0.9.0] - 2026-08-11

Driven by a fleet that had been failing quietly. A bay had been returning 500
to every collector report since it was imaged, backups were accumulating
duplicate revisions on any machine number more than one PC reported against,
and a setting that looked configurable had never been readable by the script
that consumed it. The theme of the release is making those failures visible:
each fix ships with the check, report or document that would have surfaced it.


### Changed

- The toner forecast is read as an order, not as a table. It opens with what to
  buy - grouped by part number, with a quantity - because two cartridges of the
  same part in different printers is a quantity of two, and that was a number
  the reader had to work out by hand. Below it, cartridges sit in urgency bands
  (empty / two weeks / thirty days / later) rather than in one long sortable
  list, since the question being asked is which pile a thing is in. A row is
  now a cartridge rather than a printer, carries its own part number and a
  level bar, and everything past "empty" starts collapsed. Cartridges with no
  part mapped are counted on one line instead of a line each: they still have
  to be ordered, but not from this page - the job is to map them.

### Fixed

- The toner forecast was reading the wrong end of the window. Zabbix applies a
  query's `limit` to the whole answer rather than to each item, and combined
  with an ascending sort that kept the OLDEST rows: a four-cartridge printer
  polled every five minutes writes over 100k readings in 90 days, so a "90 day"
  forecast was fitted to the first few days of the window and nothing since.
  That is where "4 days left" beside a cartridge at 20% came from - the rate
  was real, it just described a cartridge thrown away in May. Long windows now
  read hourly trends, which is the table meant for this and is a tenth of the
  rows; short ones read raw history, newest first, with a budget scaled per
  item.
- The forecast now counts down from the level it displays. It showed the live
  reading but computed days-left from the last stored one, so the two could
  disagree by a whole cartridge. A live level far above the stored run is
  treated as a swap that happened since the last reading rather than as a
  collapse in the burn rate.
- A cartridge at or below 5% reads as empty rather than as a slow drain. At 1%
  losing a tenth of a point a day the arithmetic said ten days; the printer is
  out of toner, and it is the first thing that should be ordered.
- Days-left in the forecast is per cartridge again. It was rendered in a cell
  spanning the printer's rows, which put the printer's soonest figure beside
  every supply it had - a cartridge at 20% displaying "4 days" that belonged to
  the black beside it, and a cartridge at 1% displaying weeks that belonged to
  nothing on that row at all.
- Supplies typed as floats were dropped from the forecast on any printer that
  also had an integer-typed one. The two live in different Zabbix history
  tables and the fetch stopped at whichever answered first, so half a printer's
  cartridges silently had no history at all.
- A shop-floor PC that reported the machine number of a machine ShopDB already
  knew got a 500 from the collector, on every report, forever. The reported
  machine number was being written to the PC's own `assets.assetnumber`, which
  is uniquely indexed and already held by the machine, so the insert failed with
  a duplicate-key error and the whole report was lost: operating system, boot
  time, applications, printers and access protocols never landed. The machine
  number now identifies the machine only. A new PC takes its hostname as its
  asset number, which is what the existing data already does, and an existing
  PC's asset number is never overwritten.
- Configuration backups piled up duplicate revisions on any machine number
  reported by more than one PC. A posted config was compared against the latest
  revision for the machine, so where several PCs share a number - the part
  markers do, and their configs differ by COM port - each PC's post differed
  from whichever PC posted last, nothing deduped, and the table grew by a row
  per PC per collection cycle. A backup chain is now per source PC, so an
  unchanged config is a no-op again and each PC keeps its own history against
  the machine it belongs to. Retention prunes each chain separately, so a busy
  PC's revisions can no longer push out a quiet PC's only backup, and the
  revision diff compares against the same PC's previous revision rather than
  another PC's.
- The backup collection interval could not actually be changed. The collecting
  script reads `backups_intervalhours` from the public settings endpoint before
  it holds any credential, but the plugin did not declare the key as public, so
  the endpoint never returned it and the script fell back to its built-in 24
  hours - silently. The setting looked configurable in the UI and was not.
- A backup export containing a value with an empty right-hand side (`Name=`)
  failed to parse, and with it the whole file, so that machine could never be
  backed up. The form is not strictly legal but occurs in real exports. It is
  now read as an empty string, preserving the value name.
- The 3D parts kiosk label prefix never appeared on the kiosk. The kiosk runs
  logged out, and an unauthenticated read of a setting is limited to an
  allowlist the key was not on, so the kiosk got a 404 and fell back to no
  prefix. An admin previewing the same page while logged in saw it, which is
  why it looked like it worked. A plugin now declares which of its settings a
  logged-out page may read.
- The same setting also looked like it would not save. The row did not exist on
  a site that installed the plugin before the setting was added, so the first
  save created it - under a placeholder category, where the settings page, which
  lists by category, could no longer see it. The value was in the database the
  whole time. A first-time save now files the key under the category its owner
  declares. Any row already misfiled is repaired in place on upgrade, value
  untouched. The 3D parts alert email and the employee directory host were in
  that state.
- Settings added in a later plugin version never reached a site that installed
  an earlier one. The seeding ran from `on_install` / `on_enable`, which fire
  only on a state transition, so neither ran again on an upgrade - and the
  comment claiming enable ran every upgrade cycle was wrong.
  `flask plugin upgrade-all` now seeds missing declared settings, without
  touching values a site has configured.

### Added

- A PC reporting a machine number is now linked to that machine. Until now the
  number was collected and then discarded, so a replaced PC never took over its
  bay: the retired PC kept the link and everything that walks PC to machine, the
  warranty machine column and the DNC info card among them, pointed at hardware
  that had been pulled out. The link is a `controls` relationship carrying a
  `collector:machine` origin label, so a link made by hand is never touched.
  Superseding a PC archives the old link rather than deleting it, keeping the
  history of which PC ran a machine and when. The retired PC's status is
  deliberately left alone: the collector cannot tell whether it was shelved,
  sent for repair or re-imaged for another bay, so a person decides.

  A second PC reporting a machine another PC already holds is treated as a
  claim, not a handover. A PC imaged for a machine carries that number before
  it ever reaches the floor, so the PC actually running the machine keeps the
  link while it is still reporting and still In Use, and the challenger is
  recorded as a dormant link. The handover completes on its own once the old PC
  has been quiet for a day, or immediately when someone moves it off In Use.
  Without this the two PCs traded the link back and forth on every collector
  cycle.

  Alerts for both cases go out by email and webhook, gated on a new
  `computers_machinelink_alerts` setting that ships OFF: a site may legitimately
  run several PCs on one machine number, and there the alerts fire on correct
  data. The collector response warns either way.
- A PC that drives a subordinate device is now declared, not coded. Two cases
  had arrived separately and been written twice: a metrology PC drives a CMM or
  Keyence unit that becomes a measuring-tool asset, and a part-marker PC drives
  a marker that becomes a machine asset filed under its operation. Both mint a
  device, link the PC with `controls` and archive that link on a re-image - one
  mechanism with different nouns. They are now one map, and a site can add or
  retarget an entry through a `subordinatedevice_<pctype>` setting, so the next
  case - two marking lasers or two wax-trace units on one machine number - is
  configuration rather than a code change. A malformed override falls back to
  the default instead of failing the collector push.
- `flask relationships check-shared-machines` reports machine numbers claimed
  by more than one PC, and says which are modelled and which are faults. Several
  devices genuinely sharing a number and two PCs mis-numbered at imaging look
  identical from the outside; the difference is whether anything is filed under
  the operation, which is what the check reports. Read-only.
- A part marker is its own asset. Several Telesis markers can serve one
  operation number, so treating the operation as the marker collapsed separate
  devices into one record: their configurations, which differ by COM port,
  overwrote each other in the backup history, and no question about an
  individual marker - how many there are, which port one is on, which one
  failed - could be asked at all. There is one marker per PC, so the collector
  now mints a Part Marker machine asset for a marker PC the same way it already
  mints a CMM or a Keyence unit for a metrology PC: the PC `controls` the
  marker, and the marker is `partof` the operation it serves. Because `controls`
  propagates through `partof`, control of the operation still follows from
  controlling its marker, and two markers on one operation no longer contest a
  link only one of them can hold. Backups from a marker PC file against the
  marker. Moving a marker to another operation archives the old membership
  rather than deleting it.
- Plugin contract 0.16.0: `get_settings_defaults()` lets a plugin declare the
  settings it owns (key, default, type, category, description, and whether an
  unauthenticated caller may read it). See `docs/PLUGIN-HOOKS.md`.

## [0.8.1] - 2026-08-05

Everything here shipped after v0.8.0 was tagged the same morning, driven by two
sites putting real data in for the first time. Most of it is defects that only
appear when somebody who did not build the software tries to use it.

### Fixed

- A blank optional code could be saved once and never again. A unique nullable
  column accepts any number of NULLs but exactly one empty string, so the second
  business unit with no code collided with the first and returned 500 from a
  field the form correctly showed as optional. Blank now stores as NULL, which
  covers every unique nullable column - asset numbers, hostnames, item codes,
  subnet names, gage-lab tags - not just the one that was reported. A genuine
  duplicate answers 409 with a readable message instead of a bare 500.
- A lobby display with exactly two slides never changed between them. The
  slideshow was started twice, and two timer chains advancing one slide each
  landed back on the first every cycle. With three or more slides it advanced by
  two and merely skipped one, which is why it went unnoticed. The per-slide
  duration the feed has always sent was also ignored in favour of a hardcoded
  ten seconds.
- Clicking slightly outside a modal discarded a part-filled form, in 35 modals
  across 30 files. Confirmation dialogs still dismiss that way, since they hold
  nothing to lose.
- Selecting a filter while past page one returned an empty list, because the
  filter asked for page five of a result set that now had one page.
- Model photos could not be saved: an uploaded photo sets the field to an
  application path, and the input was type="url", which demands an absolute
  address. The upload button was also hidden when creating a model.
- An empty bordered box appeared after Notes on the network device form.

### Added

- The equipment catalog travels. `flask seed catalog` loads 53 vendors, 128
  models with photos, 146 printer supply part numbers and every type vocabulary,
  so a new site can start adding printers immediately instead of retyping a
  catalog another site spent a year building. Idempotent and additive; catalog
  only, with nothing site-specific. Offered by the installer as a tick-box and
  by the operator console.
- `shopdb-admin.ps1 repair` completes an interrupted provisioning, and `check`
  now says when a server is not fully provisioned instead of leaving it to be
  inferred from 500s on unrelated pages.
- Network devices can be linked to a catalog model, and their map position is
  picked on the floor plan rather than typed as coordinates.
- An asset's vendor and type can be derived from its catalog model, by exact
  name match only, with a reviewable backfill script.

### Changed

- Labels say whose type they mean: Machine Type, PC Type, Printer Type, Device
  Type, next to the catalog's Model type.
- The 3D parts kiosk label prefix is a setting rather than one site's initials
  hardcoded in the source.
- The operator console menu is grouped by what each action touches.

## [0.8.0] - 2026-08-05

First release to carry the Windows installer. Everything below shipped after
v0.7.0 was tagged, and a complete install was exercised end to end on Windows
Server 2019 before this release was cut.

### Fixed - installer, from a real Server 2019 install

- `packaging` was imported by the plugin loader but declared nowhere. It reached
  development and CI only as a dependency of pytest, so the whole suite passed
  while a virtual environment built from `requirements.txt` alone - which is
  exactly what the installer builds - could not import the application at all.
  `tests/test_runtime_dependencies.py` now fails on any runtime import that is
  not a declared dependency.
- IIS returned 500.52 before the application was ever launched. `web.config`
  declared `<allowedServerVariables>` for the X-Forwarded-For rule, and that
  section ships `overrideModeDefault="Deny"`, so the whole file was rejected.
  The installer now permits the single variable at server level instead of
  unlocking the section for every site on the machine, and repairs a
  `web.config` an earlier build had made unusable.
- The config unlock ran before the application it unlocks existed, so the scoped
  form could never succeed on a first install and every install silently fell
  back to granting handler delegation server-wide.
- The stage 5 smoke test discarded the status code and error page it had already
  received, reporting "site did not return 200" for a fault IIS had named. It
  now records both, plus the tail of the application log.
- Database dumps were readable by every authenticated user: a directory created
  under ProgramData inherits `Users:RX`, and the owner-only ACL was applied only
  when the installer itself created it.
- The uninstaller ran the 32-bit PowerShell, which cannot see IIS, so the site,
  pool and application survived a "successful" uninstall pointing at a deleted
  directory.
- Uninstall matched applications by alias alone and would remove an unrelated
  application of the same name under another site.
- Wizard input reached a command line unchecked: unvalidated ports, a drive-root
  path that escaped its own quote, and a password written as ANSI but read back
  as UTF-8, which reported a correct non-ASCII password as wrong.
- Plugin deregistration could never succeed - it omitted `--yes` against a
  command that prompts - while the plugin directory was deleted regardless.
- Preflight rows were drawn past the bottom of the panel and silently vanished;
  the failures loop had no cap at all.

### Changed - installer behaviour

- "Is this a re-run of my install?" is answered from a durable install record
  rather than inferred from the state of the machine. Nothing on a server says
  who created its database tables, so a retry after a failed first install was
  taken for an upgrade of a working system: it demanded a mandatory backup of a
  database its own failed attempt had written, then refused to prune tables it
  had created minutes earlier. During unfinished first provisioning the backup
  is advisory and prune may force; on an established install both are unchanged.
- The installer offers every bundled plugin, so one build serves any site
  instead of one build per plugin profile.

### Added - operator documentation and diagnostics

- `docs/UPDATES-WINDOWS.md` - what operators should expect from future updates,
  bug fixes and security releases, including downtime, what is preserved, and
  the effect on other sites sharing the same IIS server.
- `docs/RELEASING-WINDOWS.md` - how to build and release, and the two known gaps.
- `deploy/windows/shopdb-diagnose.py` - collects what IIS answers, the config
  lock state, the application logs and the ACLs in one pass, scrubbing secrets
  before writing anything.

### Added - the installer itself

- Air-gapped Windows installer (`deploy/windows/installer/`). One `.exe` per
  site, built from that site's plugin profile, containing Python, the wheels,
  the SPA, the IIS modules and optionally MySQL. Operator docs:
  `docs/INSTALL-WINDOWS.md` and `docs/OPERATE-WINDOWS.md`, both shipped onto the
  server. `docs/INSTALL-WINDOWS-IIS.md` and `docs/DEPLOY-WINDOWS-IIS.md` are now
  reference-only, for hand-built servers.
- `bundle-lock.json`: an exact sha256 + size record of the installer's
  third-party payload (wheels, Python installer, IIS MSIs). Verified as set
  equality by both builders and again on the server before anything runs; there
  is no install-time override. Regenerate with `refresh-bundle-lock.ps1`.
- CycloneDX SBOM (`sbom.cdx.json`) generated on every build from
  `requirements.txt` and `package-lock.json`, covering both ecosystems, staged
  into the application tree so an air-gapped server can answer "do we carry this
  component" locally: `shopdb-admin.ps1 verify -Path <name>`.
- `shopdb-admin.ps1`, the operator console: status, start/stop/restart, logs,
  health check, backup, plugins, verify. `check -Json` emits secret-free
  structured state for pasting into a support ticket or an AI assistant.
- `build-installer.ps1`, the whole build natively on Windows, so a work PC needs
  no Bash. Shares `scripts/resolve_plugin_closure.py` with `build-site.sh`.
- URL Rewrite is bundled and the wizard asks where client IPs come from
  (`-ClientIpSource direct|proxy`). Without the rule IIS sends no
  `X-Forwarded-For` at all and every client reads as 127.0.0.1.

### Changed

- `requirements.txt` and `requirements-dev.txt` are compiled `--universal
  --generate-hashes`. Installs run under `pip --require-hashes`, so a wheel whose
  sha256 is not listed is refused. The dev lockfile is constrained to the
  production pins; the two had drifted.
- Python 3.14 across the Dockerfile, CI, `web.config` and the docs, which
  previously declared four different versions.
- The naming/style gate covers Markdown, JSON and YAML, not just code.

### Fixed

- `plugins/employees` imported `shopdb.core.models` directly, failing the
  contract-surface test on `main` since the dashboard employee-name resolver
  landed.
- `scripts/build-site.sh` copied all of `deploy/` into its own output directory,
  which recursed when the output was staged inside it - the documented Windows
  build could not complete.
- Plugin baseline migrations inherited the MySQL server's default charset: the
  utf8mb4 compiler hook lived in `migrations/env.py` and so covered the core
  chain only. It is now `shopdb/utils/mysql_charset.py`, imported by both.
  `flask db-utils preflight` reports the database's default charset.

### Added

- Configurable site timezone: a `site_timezone` site setting (default
  `America/New_York`, public-readable), editable in Settings > Site >
  Localization. Notification start/end times are entered and displayed in this
  zone, and daily-reset notification expiry is computed in it. A shared
  `frontend/src/utils/datetime.js` (Intl-based, DST-safe) does the conversion.

### Changed

- Asset detail pages (machines, PCs, printers, network devices, measuring
  tools) now share one canonical card skeleton: Identity -> type-specific ->
  status -> Location & Organization -> domain -> Custom Fields -> Warranty ->
  Relationships -> Notes -> audit footer. The location card reads "Location &
  Organization" on every page. The network device page was rebuilt into the
  family (its "Asset Information" folded into Identity, "Record Info" converted
  to the standard audit footer). Printer Notes moved out of mid-page to
  second-to-last and the printer gained an audit footer. Template reordering
  only; no data or API changes.

### Fixed

- Notification start/end times were off by the timezone offset (a 2:34 PM entry
  displayed as 6:34 PM). Times are now stored UTC and shown/entered in the site
  timezone; the calendar keys all-day events off the site-local day.
- Kiosk displays showed a white screen on login: a legacy 32-bit kiosk
  installer's autostart kept relaunching Edge at a now-dead URL. The install's
  HKLM Run value was WOW64-redirected into `SOFTWARE\Wow6432Node\...\Run` and
  survived earlier cleanup. The `gea-shopfloor-display` dispatcher now purges
  the legacy autostarts every enforce cycle across both registry views, all
  user hives, Run/RunOnce/policy-Run, and every Startup folder.
- List pages keep the current page (and search term) in the URL query, so
  paging to page 9, opening an item, and hitting browser Back returns to page 9
  instead of resetting to page 1. Applies to all 18 list views via a shared
  useListQuery composable; page 1 with no search stays a bare path.
- PC detail Installed Applications no longer 500s and silently disappears on
  real PCs (ComputerInstalledApp had no to_dict); the section renders app
  name, version, and description again.
- Employee detail skips its USB panels when the usb plugin is disabled (no
  more 404 console noise).
- Shopfloor kiosk header text is readable (light on the dark navy header).


### Added (continued)

- Collector-driven PC -> printer relationships. The computers collector schema
  gained optional `defaultprinter` (string) and `printers` (array of strings)
  fields carrying Win32_Printer identifiers. On ingest each identifier resolves
  to a printer asset (by windows name / share / hostname / asset number-name or
  a communications IP) and the PC is linked to it: the default via a
  `defaultprinter` relationship, the rest via `connectedto`. The links render in
  the shared Relationships card on both the PC and printer detail pages. The
  sync is idempotent and archives collector-created links to printers no longer
  reported (tagged `assetrelationships.label = 'collector:printers'`, so
  manually-created links are never touched); unresolved identifiers become
  response warnings, never failures. The collector response carries
  `printerlinkcount` and a `printerlinks` list. See docs/COLLECTOR-INTEGRATION.md.
- Searchable custom fields. Each custom-field definition gained a `searchable`
  flag (Settings > Custom Fields). When on, that field's stored values are
  matched by global search and a hit routes to the owning asset's detail page.
  The asset's `search_<type>_enabled` domain toggle still applies, and matches
  dedupe against built-in-field asset hits so an asset appears once. Inactive or
  non-searchable fields are never matched.
- Single-label sheet-position printing. The single asset-label page
  (`/print/asset-label/:assettype/:id`) gained an Output control that toggles
  between the standalone label (unchanged default) and placing that one label at
  a chosen cell (1-6, via a 2x3 grid picker) of a ULINE 6-up sheet, leaving the
  other five cells blank. This prints a single label onto the correct physical
  spot of a partially-used sheet instead of wasting a fresh sheet, mirroring the
  legacy shopdb behavior and complementing the batch page's start-cell offset.
  The ULINE 6-up cell layout and dimensions are replicated from
  `AssetLabelBatch.vue` (left untouched); encode resolution stays shared via
  `assetLabel.js`.

## [0.7.0] - 2026-07-12

### Added

- Email sending. A stdlib-only mail service (`shopdb/utils/mailer.py`;
  `smtplib`/`ssl`/`email`) reads the existing `email` SMTP settings
  settings-first with an `SMTP_*` env fallback, sends multipart HTML+text, and
  is a graceful no-op (logs a warning, returns False) when email is disabled or
  the host is unset. The SMTP password is never logged. Three flows use it:
  (1) New-user welcome + forced first-login password change. Admin-created users
  (POST `/api/users`) are flagged `mustchangepassword` (new `users` column,
  migration `7d23_user_mustchangepassword`, default false) and sent a
  best-effort welcome email with the facility name, username, temporary
  password, and sign-in link; the account is created even if mail fails
  (response carries a `warning`). Login returns `mustchangepassword`; the
  frontend forces the user through a new `/change-password` view (POST
  `/api/auth/change-password`, jwt-guarded) before the app, and changing the
  password clears the flag and resets lockout counters. A self-service "Change
  password" entry is also available from the user menu.
  (2) Test email. POST `/api/settings/test-email` (settings.edit) sends a probe
  and surfaces any SMTP error with the password scrubbed; wires up the Email /
  SMTP settings page "Send Test Email" button.
  (3) On-demand alert/report delivery. POST `/api/reports/email`
  (reports.export) mails `{subject, columns, rows}` as an HTML table to a
  supplied recipient or the site `alert_recipients`; an "Email report" button on
  the Warranty and Toner report pages posts the loaded rows. There is no
  scheduler: automation is an external cron hitting the endpoint with a scoped
  API token (PAT). Documented in `docs/CONFIG.md`.
- Shared asset label/code generator: a single `/print/asset-label/<assettype>/<id>`
  page (public, like the other `/print/*` routes) that any asset detail page
  opens via a "Print Label" button (machines, computers, printers, network
  devices, measuring tools). A no-print controls panel toggles the layout
  (`card` badge vs `plain` code-only), the code type (QR vs CODE128 barcode),
  and what the code encodes: the asset page link, asset number, serial number,
  a per-type custom target template, or - for measuring tools by default - the
  tool's inspection location code so every tool at one operation shares one
  code (e.g. `0615`). QR codes reuse the shared logo-overlay renderer. New
  `printing` settings seed and surface on the Printing & Labels settings page:
  `qr_target_machine`, `qr_target_computer`, `qr_target_network_device`,
  `qr_target_measuring_tool`; `label_default_style` (default `card`) and
  `label_default_codetype` (default `qr`); and a per-asset-type default for what
  the code encodes, `label_default_encodes_<type>` (machines default to their
  machine number, measuring tools to their inspection location code, the rest to
  a page link), all overridable on the label page itself. When the chosen field
  has no value (e.g. serial number on an asset with none), the label states so
  instead of rendering an empty code. Asset payloads now carry a derived
  `locationcode` (leading token of the resolved own/inherited location name).
- Batch label sheets: a "Print Labels" button on each asset list page opens
  `/print/asset-label-batch/<assettype>`, a multi-select sheet that lays the
  chosen assets onto ULINE label pages (6-up 3 in x 3 in, or a dense 72-up
  mini-label format), with a start-cell offset to reuse partial sheets. Shares
  the same code-type and encode settings/defaults as the single label, so a
  batch of measuring tools encodes each tool's inspection location code just
  like the single label does. Restores the ULINE batch printing the legacy
  shopdb had, generalized across all asset types.
- Support-team contact UX: the settings Support Teams page now manages each
  team's contacts in a per-team "Contacts (N)" modal (name, SSO, active, plus
  Add/Edit/Delete) instead of an inline row expander, and the application
  detail Support card renders Email (`mailto:`) and Microsoft Teams chat
  (`teams.microsoft.com/l/chat`) action buttons for every contact that has an
  SSO. Both link targets derive as `sso@<domain>` from a new `site` setting
  `contact_email_domain` (default `geaerospace.com`; blank hides the buttons),
  surfaced in Site & Facility settings under Naming & Patterns and read on the
  frontend via `getContactEmailDomain()`.
- Plugin `get_permissions` hook (contract 0.10.0) so a plugin declares the RBAC
  permissions its own routes enforce, instead of core accumulating every
  plugin's permissions in `Permission.PERMISSIONS` (plugin-is-the-product). The
  core catalog (`Permission.CORE_PERMISSIONS`) now holds only genuinely core
  sets (assets, applications, reports, settings, users, audit, apitokens,
  collector); the 36 permissions for machines, computers, printers, network,
  knowledgebase, notifications, usb, warranty, and measuringtools moved into
  each owning plugin's hook. New core helper `full_permission_catalog()` merges
  core plus every ENABLED plugin's permissions and backs all three consumers:
  `flask seed permissions`, the role grid (`GET /api/users/permissions`), and
  API-token scope validation (`ApiToken.unknown_scope_names`). Plugin install
  and enable seed the plugin's own permissions idempotently. A disabled plugin
  drops out of the catalog (no new scope grants or role assignments), but its
  existing `Permission` rows and role links persist so current roles keep
  working. Docs: `docs/PLUGIN-HOOKS.md` new section, `docs/PLUGIN-GUIDE.md`
  permissions walkthrough rewritten to the hook, `docs/PLUGIN-QUICKSTART.md`
  hooks table row.
- Personal API tokens (PATs) so scripts and integrations authenticate without
  the hourly-expiring login JWT (immediate consumer: long legacy-import runs
  that die when the JWT expires mid-run). New core `apitokens` table + migration
  `7d21_apitokens` (stores only the sha256 hash of each secret; the full secret
  `shopdb_pat_<40 hex>` is shown ONCE at creation). New core blueprint
  `/api/apitokens` (list own / admin `?all=true`; create; rename or deactivate;
  revoke). A `Bearer shopdb_pat_...` header is recognized before any JWT decode
  by a before_request shim that mints a request-scoped JWT for the token's
  owner, so the entire existing auth+authz stack (jwt_required,
  require_permission, require_role, import mode, current_user) authenticates the
  PAT as its owner with zero decorator changes; an invalid, revoked, or expired
  PAT gets a clean 401. `lastusedat` is stamped on use (throttled to at most one
  write per 60s). Any authenticated user manages their own tokens; admins may
  list or revoke anyone's. New Settings > API Tokens page (`ApiTokensList.vue`)
  with a create modal that reveals the secret once (copy button) and an admin
  All Tokens section. Docs: `docs/IMPORT-API.md` and `docs/CONFIG.md` updated to
  recommend a PAT for imports. Core feature; no plugin-contract change.
- Optional permission scopes on personal API tokens. A token MAY carry a scopes
  list (permission names, migration `7d22_apitokens_scopes` adds the nullable
  `apitokens.scopes` JSON column); NULL keeps the original behavior (acts as its
  owner). A scoped token grants ONLY the listed permissions, intersected with
  what the owner actually holds at use time, and SUSPENDS the admin-role bypass,
  so a scoped token minted by an admin is genuinely limited: it is denied on
  role-gated (`require_role`) endpoints and gets no import mode. The shim mints
  the request JWT with a `patscopes` claim that `require_permission`,
  `require_role`, and `import_mode_active` read; normal login JWTs carry no such
  claim and are unaffected (zero regression). Scopes are validated at write time
  against the token OWNER's permissions (the scope ceiling - a token can never
  grant more than its owner holds; when an admin edits another user's token the
  ceiling is that owner's permissions), rejecting unknown or unheld names 400.
  Minting/managing tokens now requires the new `apitokens.create` permission
  (category `apitokens`; admins hold it by default, grantable via the roles UI)
  rather than being open to any authenticated user. The Settings > API Tokens
  create/edit modals gain a "Restrict permissions" section (a category-grouped
  checkbox grid limited to the permissions the creator holds) and the token
  lists show a full-access / N-permissions access chip.
- Managed collector service tokens: the collector ingest API
  (`/api/collector/<plugin>` + the legacy `/pc` `/apps` `/heartbeat` `/bulk`
  `/status` endpoints) now ALSO accepts a managed API token scoped to the new
  `collector.ingest` permission (category `collector`), on top of the existing
  `COLLECTOR_API_KEY[_<PLUGIN>]` env keys (which stay supported as a
  bootstrap/legacy fallback - nothing breaks). The token may be presented in
  `X-API-Key` (as GE-Enforce sends today) OR as an `Authorization: Bearer`
  token; both transports validate the PAT the same way the login shim does
  (hash lookup, active, unexpired, active owner) via a shared
  `resolve_api_token` helper refactored out of `apitoken_auth.py`, require
  `collector.ingest` in the token's scope list AND that the owner holds it, and
  stamp `lastusedat` (same 60s throttle). A token scoped to ONLY
  `collector.ingest` is a collector service token: it authorizes the collector
  API and NOTHING else - the existing scoped-token machinery denies it on every
  permission- and role-gated route and on import mode, so a leaked collector
  token cannot touch the regular API. Recommended flow (documented): an admin
  mints the scoped token (the scope suspends the admin bypass, containing it);
  rotate by minting a new one, deploying via `site-config.json`, watching
  `lastusedat`, then revoking the old. The Settings > API Tokens create modal
  gains a "Collector service token" quick-preset (pre-selects only
  `collector.ingest`). Docs: `docs/COLLECTOR-INTEGRATION.md` (new "Managed
  collector tokens" section) and `docs/CONFIG.md`. Core feature; no
  plugin-contract change.
- Vendor-model photos on asset detail heroes: computers and printers now
  surface the linked model's `imageurl` in their extension payloads (the
  field machines already exposed), and the machine, PC, printer, network
  device, and measuring tool detail pages render the photo in the hero card
  when present (hidden cleanly when absent). Network devices and measuring
  tools have no model link yet, so their heroes stay photo-less until one
  is added.
- Dualpath "single machine" site toggle (`dualpath_single_machine`, default
  on). A Dualpath relationship pair is one physical dual-bay machine (single
  controller, bay-selector switch); when on, the machines list, dashboard and
  machines-by-type counts, and the floor map collapse each pair to one entry
  (the lower natural-sort assetnumber is PRIMARY; the SECONDARY bay is hidden)
  and show a combined `2007 / 2008` label. The data model is unchanged (both
  bay records always exist); detail pages stay per-bay and always show a
  sibling-bay banner regardless of the toggle. Contract surface (plugin
  contract bumped 0.8.0 -> 0.9.0, additive): new `shopdb.api` helpers
  `resolve_dualpath_pairs` and `dualpath_single_machine_enabled`, consumed by
  the machines plugin to collapse pairs contract-purely.
- Relationship propagation, wired and data-driven: relationship types
  declare propagation-through pairs (relationshiptypepropagations M:N,
  replacing the never-consumed single column); creating a controls link on
  one Dualpath bay auto-creates it on the partner bay, and
  `flask relationships propagate` backfills existing data.
- Employee photos, mode-aware: self-hosted directory employees support
  upload/replace/delete (admin), served publicly for kiosk cards; external
  directory mode passes the HR-supplied picture URL through read-only. One
  resolver feeds the shopfloor recognition/recert cards and the employee
  detail hero in either mode.
- Vendor-model photo management. New admin-gated core endpoints
  `POST /api/models/<modelid>/image` (multipart `file`, png/jpg/jpeg/gif/webp/svg,
  one image per model, replace semantics) and
  `DELETE /api/models/<modelid>/image`, plus the public
  `GET /api/models/image/<filename>` serve route. Uploads land in
  `instance/modelimages/` (survives upgrades, backed up with the rest of
  `instance/`) and set `models.imageurl` to the served URL; the manual Image URL
  field still accepts external URLs and the shipped `/images/models/*` assets
  (upload is additive). Delete only removes files we own under the instance dir.
  The Models settings page grows a thumbnail, Upload/Replace, and Remove
  controls in the edit modal. Asset hero images (e.g. the machine badge) read
  `imageurl` unchanged, so uploaded photos render with no consumer changes.

- Application support teams with contacts, replacing the legacy
  supportteams/appowners pair. New core `supportteamcontacts` table (multiple
  named contacts per team, ordered by `sortorder`); `supportteams` keeps
  `teamname` (now unique) and `teamurl` (a ServiceNow group deep link) and
  sheds the single-owner `appownerid` FK. New core blueprint at
  `/api/supportteams` (team + nested contact CRUD, admin-gated; `?teamname`
  exact-match lookup for import; delete a team 409s while any application still
  references it). Migration `7d18_supportteamcontacts` migrates each legacy
  team's app owner into one contact. Application payloads now flatten
  `supportteamname`, `teamurl`, and the team's active `contacts`; a Support
  card on the application detail page and a new `settings/supportteams`
  management page render them.

- Import mode: a complete, idempotent HTTP migration surface so a migration script
  can import the classic ASP shopdb through the API alone (no direct DB writes).
  - Contract surface (plugin contract bumped 0.7.0 -> 0.8.0, additive): new
    `shopdb.api` helpers `apply_import_timestamps`, `import_mode_active`,
    `parse_import_datetime` in `shopdb/utils/import_mode.py`. When the caller is
    an admin AND sends header `X-Import-Mode: true`, create/update endpoints
    accept optional `createddate` / `modifieddate` (ISO or legacy
    `YYYY-MM-DD HH:MM:SS`, naive-UTC) and preserve them instead of stamping now.
    Non-admin or missing header: the fields are ignored exactly as before.
    Wired into every timestamped import target: assets (all five type plugins),
    vendors, models, modeltypes, businessunits, locations, operating systems,
    applications, knowledge base, USB devices, and asset relationships.
  - Natural-key exact-match lookup filters for the documented
    lookup-then-upsert idempotency recipe: `assetnumber` on all five asset
    plugin list endpoints; `vendor`, `modelnumber`, `modeltype`,
    `businessunit`, `locationname`, `osname`/`osversion`, `appname`,
    knowledge base `linkurl`/`shortdescription`, warranty `servicetag`/`vendor`,
    and notification `ticketnumber`.
  - Backdated event history: in import mode the selfhosted USB checkout/checkin
    endpoints accept optional `checkouttime` / `checkintime` overrides so
    migrated `usbcheckouts` rows keep their real event times.
  - New operator manual `docs/IMPORT-API.md` grounded in the real `prodscratch`
    legacy schema: order of operations, a full table-by-table mapping, honest
    no-target list with dispositions, a worked idempotent Python importer, and
    row-count parity checks.

### Changed

- System Settings is no longer one tabbed page. The inner tab bar is gone and
  each section is its own routed settings page reached through the settings
  rail: ServiceNow, Zabbix Supplies, Dell Warranty, and Collector PC Types
  (the former Integrations dumping ground, now split three-plus ways), plus
  Branding, Floor Map, Printing & Labels, Email / SMTP, Authentication,
  Audit & Logging, Asset Identifiers, and Global Search. The rail regroups
  these under Site & Facility, Integrations, Communication, Search & Identity,
  and Access & Security. Shared load/save/upload plumbing moved into a
  `useSystemSettings` composable so the pages stay thin. Old bookmarks keep
  working: `/settings/system` and every `/settings/system?tab=<key>` redirect
  to the matching new page.

### Fixed

- Audit log: hovering a user's SSO now shows their full name (best-effort,
  resolved from the employee directory in either mode).
- Refreshed the internal status docs to match the code (project active
  state, CONTRACT-STABILITY.md and README plugin list at contract 0.10.0),
  corrected the get_asset_panels endpoint path in the hook docstring, and
  removed leftover debug console.log lines.
- Measuring tools wired into the remaining cross-cutting surfaces an audit
  found them missing from: generic asset serialization (typedata + pluginid,
  which also fixes relationship-card links to tools), map subtype
  filtering/coloring and the MapEditor filter, dashboard totals, warranty
  asset links (via a new by-asset detail route), and the two ADR-010 hook
  declarations (presentation route token corrected; the calibration
  map-overlay endpoint now actually exists). The login avatar also resolves
  through the employee-photo helper, so self-hosted uploads show.
- Measuring tools are now wired into the asset-identifier matrix and global
  search. The Settings identifier matrix gains a Measuring Tool column and the
  gauge-lab and maintenance reference inputs/rows on the measuring-tool form
  and detail pages honor those per-type toggles (a maintenance-reference field
  was added, matching the other asset types). Global search gains a Measuring
  Tools domain toggle and filter chip, routes measuring-tool hits to
  `/measuringtools/<id>` (previously the generic `/assets/<id>` fallback), and
  matches on `gaugelabreference` so a gage-tag lookup resolves the tool.
- Site & Facility settings page renders booleans as toggles and the
  directory-mode settings as dropdowns, with labels and help text for every
  field (no more raw keys or type-true/false boxes).
- System Settings tabs follow the URL: clicking a settings-rail link that
  only changes the ?tab= query (Branding, Floor Map) now switches the right
  panel, tab clicks update the URL, and browser back/forward restore tabs.
- Following a relationship link between two assets of the same type now loads
  the destination page instead of stale content (router-view keyed on path;
  query-only URL changes still avoid a remount).
- Asset relationships card no longer lists a symmetric peer twice. Relationship
  types gain `relationshiptypes.isdirectional` (migration
  `7d19_relationshiptype_directional`; seeded false for the connection-like
  types Dualpath, connectedto, Cluster Member, Serial Cable, Direct Ethernet,
  USB, WiFi, true for controls/Controlled By/Backup For/Master-Slave/partof/
  defaultprinter). The card now collapses every stored direction row of a
  symmetric type into one direction-blind "Connected" entry per peer (deleting
  it removes all collapsed rows), while directional types drop the
  Outgoing/Incoming headers for inline `Type -> peer` / `<- Type from peer`
  phrasing. The type CRUD and the per-asset relationships endpoint carry
  `isdirectional`; the Relationship Types settings page gains a Directional
  toggle.

## [0.6.0] - 2026-07-11

### Added

- measuringtools plugin (ADR-005): gage-lab instruments as Asset extensions
  with type lookup (color-coded), calibration tracking (derived
  overdue/due-soon/current status), calibration report, and full frontend.
  Built as the framework exemplar; docs/PLUGIN-GUIDE.md walks through its
  construction step by step as the plugin-system tutorial.
- CSV export on the Warranty and Toner report pages; per-report filter
  controls (business unit, asset type, location, application, limit) on the
  inline core reports; report open-state is URL-backed and deep-linkable.
- Per-plugin Alembic migration chains (ADR-008): every bundled plugin now
  carries its own chain with a stamp-only anchor; new plugin schema changes
  land in `plugins/<name>/migrations/`, never the core chain. Deploys run
  `flask plugin upgrade-all` after `flask db upgrade`.
- Frontend plugin route gating (ADR-009): a disabled backend plugin's pages
  redirect to the dashboard; new public `GET /api/plugins/enabled`.
- `get_reports()` plugin hook (plugin contract 0.5.0 -> 0.6.0): plugins
  contribute their own report cards; warranty and toner cards moved off the
  hardcoded frontend list.
- Reports hub grouped by category with a search filter.
- Configurable QR label targets: `qr_target_printer` / `qr_target_usb`
  settings (blank = the asset's own page, else a URL template with
  placeholders) and a `usb_label_style` barcode/QR toggle for USB
  mini-labels. New Settings > Printing & Labels section.
- Site palette theming: optional `brand_primary_dark_color`,
  `brand_accent_color`, `brand_sidebar_color` settings applied at bootstrap.
- Collector integration guide rewrite: header-only auth reference and a
  paste-ready GE-Enforce PowerShell reporting function.

### Changed

- Equipment -> machines rename (backend). The equipment plugin is now the
  machines plugin: `/api/equipment` -> `/api/machines`, tables
  `equipment`/`equipmenttypes` -> `machines`/`machinetypes` (columns
  `equipmentid` -> `machineid`, `equipmenttypeid` -> `machinetypeid`,
  `equipmenttype` -> `machinetype`), permissions `equipment.*` ->
  `machines.*`, assettype value `equipment` -> `machine`. The legacy core
  `machinetypes` lookup (it types the vendor MODELS catalog, not machine
  instances) is renamed to `modeltypes` (`/api/machinetypes` ->
  `/api/modeltypes`, `models.machinetypeid` -> `models.modeltypeid`) to
  free the name. Data flips migrate assettypes, auditlog entitytype,
  settings keys (`identifier_*_equipment_enabled` ->
  `identifier_*_machine_enabled`, `search_equipment_enabled` ->
  `search_machine_enabled`), and permission rows in place; plugins.json
  registry entries carry over automatically. Upgrade: run
  `flask db upgrade` then `flask plugin upgrade-all`.

- Inter (variable) replaces Roboto, bundled locally - no Google Fonts
  fetch, so air-gapped installs render correctly. Tables use tabular
  numerals.
- ServiceNow defaults point at the current geaerospaceqa.service-now.com
  global search (search, incident, and change links).

### Fixed

- USB frontend remapped to the actual API shape (`device_id` /
  `device_desc`): device list, detail, form, label batch, and the employee
  profile's checked-out/history panels were all reading dead legacy fields.
- External-mode `GET /api/usb/checkouts/active` now honors the `badge`
  filter.
- Warranties list page no longer demands login (matches every other list
  page; reads were already public).
- Removed the dead legacy Warranty Status report (always-zero buckets from
  a retired column); the warranty plugin's report is the real one.
- Pruned dead usbApi client methods that had no backend routes.

## [0.5.0] - 2026-07-10

First release cut with a version, tag, changelog, and CI. Focused on
letting other GE Aerospace sites stand up their own self-hosted instance
(single-tenant per ADR-004).

### Added

- First-run setup wizard (`/setup`): creates the initial superadmin
  in-app, configures each plugin (create tables here vs connect your own
  database), uploads light/dark floor-map blueprints, and seeds starter
  reference data.
- Self-hosted employee directory and USB plugins: in-app management plus
  CSV import, no external database required. Both ship default-disabled
  with an enable-time provisioning note.
- Dell warranty plugin: real Dell provider, bulk warranty sync,
  add-warranty from asset pages, PC hero warranty badge, disk-cached Dell
  API token.
- Custom fields, and a two-pane settings shell with tabbed, searchable
  System Settings and Settings index pages.
- Dashboard defaults (visitor-IP to business-unit mapping) for kiosk
  displays; printer installer endpoint (data plus floor-map positions).
- Global toast notifications replacing `alert()` calls.
- Multi-stage Docker build that compiles the Vue frontend and ships
  `frontend/dist`, which Flask serves.
- Documentation overhaul: new CONFIG, UPGRADE, and BACKUP-RESTORE guides;
  reconciled README, DEPLOY, status docs, and ROADMAP.
- ADR-007 (product versioning and releases), CHANGELOG, and best-effort
  Gitea Actions CI (backend tests, naming/style gate, frontend build).

### Changed

- Plugin contract (`__contract_version__`) settled at 0.5.0: full plugin
  import surface exposed via `shopdb.api`, dead search hook removed, and
  the dashboard-widgets hook wired to a real consumer.
- Role-based access control now enforced on write routes, including
  admin-only guards on dashboard-defaults writes.
- Branding, ServiceNow integration, employee-ID pattern, printer
  hostname template, and floor-plan blueprints are settings-driven and
  per-site configurable, with GE defaults preserved as shipped fallbacks
  (branding and floor-plan configurability landed in this release; some
  consumer wiring continues under Unreleased).

### Security

- Dashboard-defaults writes now require admin authorization instead of
  any authenticated user.
- Collector error responses no longer leak exception detail; failures are
  logged server-side with generic client-facing messages.
- Login rate limiting added (IP-based fixed window) on top of the
  existing account lockout.

### BREAKING

- Collector API key must now be sent in the `X-API-Key` header. The
  api-key-in-querystring fallback has been removed. Update any collector
  integration that passed the key as a query parameter. See
  `docs/COLLECTOR-INTEGRATION.md`.
