+## [Unreleased]
+
+SLM live monitoring — fan-out feed + cache-first reads.  Targets **0.14.0**.  The throughline: the NL-43 allows exactly **one** TCP connection at a time, so every page that opened its own device stream (or sent its own `Measure?`/DOD on load) was competing for that single connection — a second viewer saw nothing, and dashboard loads stole polling resolution from the live feed.  This release moves Terra-View entirely onto SLMM's shared, cached monitoring: one DOD poll loop per device, fanned out to all viewers; dashboards read SLMM's cache (a DB read on SLMM's side) instead of touching the device; and the live panels populate instantly from cache on open, upgrading to the live WS only on demand.  Paired with the SLMM-side work (adaptive poll rate, unreachable backoff, device-offline alert) on SLMM branch `dev`.
+
+### Added
+
+- **Fan-out `/monitor` feed consumption.**  The unit live view (`partials/slm_live_view.html`) and the dashboard live tile (`sound_level_meters.html`) now subscribe to SLMM's shared per-device monitor over `WS /api/slmm/{unit}/monitor` instead of each opening its own device stream.  Any number of clients attach without each consuming the NL-43's single connection — the "second viewer sees nothing" contention is gone.  A WS proxy handler for `/monitor` was added to `backend/routers/slmm.py`.
+- **L1/L10 percentile lines + cards.**  Both the per-unit live chart and the dashboard card chart now plot L1 (purple) and L10 (orange) alongside Lp/Leq, and the KPI cards show L1/L10.  Sourced from the DOD feed's `ln1`/`ln2` (DRD streaming can't carry percentiles, DOD can).  Missing/`-.-` values leave a gap rather than dropping the line to 0.
+- **Live-chart backfill on open.**  Charts seed from SLMM's downsampled DOD trail (`GET /api/slmm/{unit}/history?hours=2`) so a viewer sees recent trend immediately instead of a blank chart that fills one point per second.
+- **Live Measurements panel auto-populates from cache.**  Opening the dashboard panel fills the KPI cards from cached `/status` and backfills the chart from `/history` — pure cache reads, no device hit.  Shows a measuring badge (● Measuring / ■ Stopped) and a freshness stamp ("as of 3:48 PM (10s ago)", amber + "cached" when stale).  Re-polls the cache every 15s while open; **Start Live Stream** upgrades to the live WS and no longer wipes the backfilled trail (chart point cap raised 60 → 600).
+- **Refresh buttons** — one per device-list row, one in the panel header.  On-demand, user-initiated single device read via `GET /api/slmm/{unit}/live` (which also refreshes SLMM's cache), with a spinner + success/error toast, then reloads the device list.
+- **Per-unit live-monitoring (keepalive) toggle on `/admin/slmm`** — turns a device's server-side keepalive feed on/off (`POST /monitor/start|stop`), so alerting can keep a device's feed running with no browser attached.
+
+### Changed
+
+- **Dashboard device list + command center read SLMM's cache, not the device.**  `slm_dashboard.py`'s `get_slm_units` pulls each unit's cached status from SLMM's `/roster` (one call, a SLMM DB read) for the badge + freshness; the command-center `get_live_view` reads cached `/status` instead of sending `Measure?` + a fresh DOD on every load.  This stops dashboard loads from stealing the device's single connection from the live monitor.  The elapsed-measurement timer still works because `measurement_start_time` is now included in the cached `/status` response.
+- **Device-list freshness reflects real monitoring.**  The "Last check" line now uses SLMM's cached `last_seen` (which the monitor advances on every successful poll) via `unit.cache_last_seen`, instead of the `slm_last_check` roster field the monitor never updates.  The status badge also treats `Measure` as Measuring, matching the panel and SLMM's cache.
+- **Status badge relocated** to the card's bottom meta row (next to "Last check"), off the top-right corner where it collided with the chart/gear/refresh action icons.
+
+### Fixed
+
+- **Deploy/bench threw `can't access property "dispatchEvent", e is null`.**  `toggleSLMDeployed()` and the save-config path called `htmx.trigger('#slm-list', 'load')` guarded only by `typeof htmx !== 'undefined'`; no page has a `#slm-list`, so htmx resolved null and called `null.dispatchEvent(...)`.  The deploy POST had already succeeded, so the operator saw both the green success **and** a red error.  Both call sites now guard on the element existing (`slm_settings_modal.html`).
+- **Monitor WS proxy leaked `CancelledError` / "task exception never retrieved"** on stream stop — the cleanup awaited pending tasks but only caught `Exception`, missing `CancelledError` (a `BaseException`).
+- **"No recent check-in" shown even on an actively-monitored device** — the row read the stale `slm_last_check` roster field instead of SLMM's live cache (see Changed).
+- **L1/L10 KPI cards populated but the chart drew no L1/L10 lines** — the card chart only had Lp + Leq datasets.
+
+### Upgrade Notes
+
+Requires the **matching SLMM build (branch `dev`)** — Terra-View now depends on SLMM's fan-out `/monitor` feed, `/history` trail, `/status` carrying `ln1`/`ln2` + `measurement_start_time`, cached `/roster` status, and the `monitor_enabled` keepalive flag.
+
+```bash
+# SLMM (branch dev) — REBUILD + MIGRATE (or you'll get `no such column: nl43_status.ln1` 500s)
+cd /home/serversdown/slmm && docker compose build slmm && docker compose up -d slmm
+docker exec terra-view-slmm-1 python3 migrate_add_ln_percentiles.py
+docker exec terra-view-slmm-1 python3 migrate_add_monitor_enabled.py
+
+# Terra-View — NO migration; templates are baked into the image, so rebuild (don't just restart)
+cd /home/serversdown/terra-view && docker compose build terra-view && docker compose up -d terra-view
+```
+
+The two builds must ship **together**.  Note the `docker-compose.yml` container was renamed for clarity (now `terra-view-terra-view-1`) — adjust any `docker exec` scripts that referenced the old name.
+
+---
+
+### Client portal *(new — read-only client-facing view)*
+
+A scoped, read-only portal at **`/portal/*`** where a client sees only *their*
+locations, live.  Built inside Terra-View (no new service), reusing the cached
+SLMM feed; every route resolves the client through one swappable
+`get_current_client` gate, so the interim magic/open-link auth can be replaced
+(M4) without touching routes or templates.  Strictly read-only — no device control.
+
+#### Added
+
+- **Per-client scoping + interim auth.**  New `Client`, `ClientAccessToken`, and a
+  `Project.client_id` FK.  A signed (HMAC) session cookie carries the access-token
+  id, re-validated against the DB each request (revoke kills live sessions, with
+  server-side expiry).  Entry via a magic link (`/portal/enter/{token}`) or a
+  dev-only plain link (`/portal/open/{id}`, `PORTAL_OPEN_LINKS`, **default off**).
+- **Live location view.**  KPI cards (Lp/Leq/Lmax/L1/L10) + chart populate
+  instantly from cache, then upgrade to a real **~1 Hz WebSocket stream** scoped to
+  the client's unit (a scrubbed bridge to the SLMM fan-out feed).  The stream
+  **auto-closes when the tab is hidden** (Page Visibility) and after a 15-min idle
+  cap, so an abandoned tab can't pin the device at 1 Hz / burn cellular.
+- **Locations overview.**  Live status map (level-colored dots, dark/light CARTO
+  tiles) + a status rollup (live/offline counts, "loudest now").  Leq is the
+  headline metric.
+- **Alerts (config → surface → 24/7).**  Threshold-rule config on the SLM detail
+  page (proxying SLMM's alert CRUD); breach **history + ack** internally and a
+  read-only, scrubbed history + current-alarm banner + **"your alert limits"** panel
+  in the portal; enabling a rule pins that device's monitor on so alerts evaluate
+  round-the-clock.
+- **Operator sharing tools.**  A **"View client portal"** preview button and a
+  **"Copy client link"** modal (mint / list / revoke magic links) on the project
+  page, plus a `backend/portal_admin.py` CLI.
+- **Field-instrument design.**  Distinctive themed portal — Hanken Grotesk UI +
+  IBM Plex Mono readouts, panel system, pulsing live dot, staggered reveal — with a
+  **light/dark toggle** (light default, persisted, no-flash).
+
+#### Security
+
+- All scoping enforced server-side (404-not-403, no existence leak); client
+  endpoints return **scrubbed** projections (no device-health/internal ids); WS
+  frames whitelisted; operator-set strings HTML-escaped before injection (XSS).
+  Pre-merge code review hardened cookie expiry, open-links default, and the slug
+  collision.  Remaining hardening (reverse proxy, TLS, `SECRET_KEY`, M4 auth) is
+  tracked in `docs/CLIENT_PORTAL.md` → "Security hardening backlog".
+
+#### Upgrade Notes
+
+- **Migration:** `docker compose exec web-app python3 backend/migrate_add_client_portal.py`
+  (adds `projects.client_id`; the `clients` / `client_access_tokens` tables
+  auto-create).
+- Set a real **`SECRET_KEY`** in any internet-facing env (signs session cookies),
+  and keep **`PORTAL_OPEN_LINKS=false`** there.
+- Portal alerts depend on the **SLMM `dev`** alert engine (rules/events/evaluator +
+  cooldown + keepalive coupling) — same build pairing as above.
+

+
+## [0.13.3] - 2026-06-05
+
+Calibration sync from SFM events.  Closes the manual data-entry loop on calibration dates — Terra-View now pulls `device.calibration_date` from each seismograph's most recent event sidecar once a day and updates `RosterUnit.last_calibrated` when the device reports something fresher than what's stored.  Manual edits still win when they're newer than the latest event; a fresh event arriving later supersedes the manual edit.  Adds a "Sync now" button under Settings → Advanced → Calibration Defaults for on-demand runs, and a `docs/ROADMAP.md` to track in-flight + deferred work.
+
+### Added
+
+- **Calibration sync service** (`backend/services/calibration_sync.py`).  Per-unit: fetches `/db/events?serial={id}&limit=1` then `/db/events/{event_id}/sidecar` via the SFM proxy, reads `device.calibration_date`, and writes it to `RosterUnit.last_calibrated` with `next_calibration_due` recomputed from `UserPreferences.calibration_interval_days`.  Every change is logged in `UnitHistory` with `source='sfm_event'` and `notes="Synced from event {id}"` so the unit detail history timeline reflects auto-sync activity alongside manual edits.
+- **Conflict rule: events-as-truth, manual wins when newer.**  Three outcomes per unit:
+  - `already_in_sync` — stored date already matches the event's calibration date.
+  - `skipped_manual_newer` — the latest `UnitHistory` change for `last_calibrated` happened *after* the event's timestamp, so the manual edit is preserved.  Only a future event can supersede it.
+  - `updated` — the event is newer (or no manual edit exists), so the stored date is replaced.
+- **Daily background job at 03:15 local** via the `schedule` library + a worker thread (modeled on `backup_scheduler.py`).  Started in `main.py`'s startup hook, stopped on shutdown.  Does not run on boot — first sync after a server start fires at the next 03:15.
+- **`POST /api/calibration/sync`** — runs a full sync immediately and returns a summary `{checked, updated, skipped_manual_newer, already_in_sync, no_event, no_sidecar, no_cal_in_sidecar, errors, results: [...]}`.  Powers the Settings button.
+- **`GET /api/calibration/sync/status`** — returns scheduler state + the last run's summary including per-unit `{unit_id, action, old, new, event_id}` rows.  Useful for diagnostics: `curl localhost:8001/api/calibration/sync/status | jq`.
+- **Settings UI: "Sync from SFM events" section** under the Calibration Defaults card (Advanced tab).  Click "Sync now" → result line shows counts: `Checked N · Updated N · Already in sync N · Manual kept N · No event N`.
+- **`docs/ROADMAP.md`** — first-pass roadmap pulling deferred items from `CLAUDE.md`'s focus block, in-code TODOs (`photos.py` GPS migration → `MonitoringLocation`, `device_controller.py` SFM Phase 2 stubs, `modem_dashboard.py` ModemManager backend, `dashboard.html` geocoding), and the README's long-standing "Future Enhancements" wishlist.  Grouped into In Flight / Near-Term / Medium-Term / Wishlist; intended as a living document.
+
+### Fixed
+
+- **Prod startup crash: `ModuleNotFoundError: No module named 'schedule'`**.  The `schedule` library wasn't pinned in `requirements.txt` even though `backend/services/backup_scheduler.py` has been using it since v0.4.x — the dev image happened to have it from an earlier manual `pip install`, but a clean prod rebuild dropped it.  Added `schedule==1.2.2` so the new calibration scheduler (and the existing backup scheduler) survive a clean rebuild.
+
+### Upgrade Notes
+
+No DB migration required — `UnitHistory.source` and `RosterUnit.last_calibrated`/`next_calibration_due` already exist.  Rebuild only:
+
+```bash
+cd /home/serversdown/terra-view
+docker compose build terra-view && docker compose up -d terra-view
+```
+
+After rebuild, Settings → Advanced → "Sync from SFM events" → "Sync now" to backfill in one shot; otherwise wait for the 03:15 job.

+
+## [0.13.2] - 2026-05-30
+
+PWA-cache fix for mobile operators.  v0.13.0 added the inline PDF preview, `.TXT` download, and Review form to `event-modal.js`, but mobile devices using Terra-View as a PWA never saw any of it — the service worker had `CACHE_VERSION = 'v1'` (unchanged since v0.12.x), so the activate handler never evicted the stale cache and mobile users kept getting served the pre-v0.13.0 modal forever.
+
+### Fixed
+
+- **Service worker cache version bumped + tied to the app version**.  `CACHE_VERSION` in `backend/static/sw.js` is now `'v0.13.2'`, which causes the SW's activate handler to delete the old `sfm-static-v1` / `sfm-dynamic-v1` / `sfm-data-v1` caches on first visit after the upgrade.  Going forward the convention is: any release that touches a static asset must bump `CACHE_VERSION` to match `backend/main.py`'s `VERSION`.  Comment in `sw.js` documents this.
+- **`event-modal.js` precached** alongside `mobile.js` / `offline-db.js` etc.  Lifecycle is now tied to the SW version bump explicitly — old modal JS gets evicted on activate, new modal JS is fetched and cached during install.
+
+### What mobile users will see after deploy
+
+On next page navigation the SW update check fires, the new SW installs (skipWaiting), activate evicts the v1 caches, `controllerchange` fires, the page reloads with the v0.13.x modal.  On the worst-case device (no recent visit), it might take up to an hour for `registration.update()` to pick up the new SW — operators can force-refresh by closing and re-opening the PWA, or by clearing site data once.
+
+---
+
+## [0.13.1] - 2026-05-29
+
+Same-day patch on top of v0.13.0.  Fixes the mic-chart unit default — v0.13.0 shipped with `dBL` as the default, but the PDF report renders the mic axis in psi, so the website chart and the printed report didn't match.  Operator caught it within an hour of rollout.  Also relabels the modal's "Captured at" field to "Time received" so it isn't mistaken for the device's trigger time.
+
+### Fixed
+
+- **Event-detail modal: mic chart now defaults to psi**, matching the PDF report's mic axis.  The waveform/histogram chart's mic channel now renders in raw psi by default; operators who specifically prefer dB(L) on charts can flip it via Settings → General → "Event Report — Mic Channel Units".  Peaks everywhere else (table tiles, modal Peaks section, KPI summaries) stay in dB(L) as before — this is strictly a chart-axis change.
+- **Modal label: "Captured at" → "Time received"** (+ tooltip clarifying it's the SFM ingestion time, not the unit-local trigger time at the top of the modal).  Same change in seismo-relay's standalone webapp for consistency.
+
+### Migration Notes
+
+The bundled `backend/migrate_add_mic_unit_pref.py` is now idempotent across both the v0.13.0 "add column" path and the v0.13.0 → v0.13.1 default flip.  Existing rows sitting at the original `'dBL'` default (i.e. nobody touched the setting yet — true for almost everyone) get bumped to `'psi'` on migration.
+
+```bash
+cd /home/serversdown/terra-view
+docker compose build terra-view && docker compose up -d terra-view
+docker exec terra-view-terra-view-1 python3 /app/backend/migrate_add_mic_unit_pref.py
+```
+
+If you _did_ deliberately set the chart to dB(L) via Settings between v0.13.0 rollout and this patch, the migration will reset it — one click in Settings to restore.  Trade-off considered acceptable given the very small user base and the freshness of the v0.13.0 release.
+
+---
+
+## [0.13.0] - 2026-05-29
+
+The "SFM integration Phase 1" release.  Closes the gap between Terra-View and the standalone SFM webapp on port 8200 — operators no longer need to bounce between the two for routine event review.  The shared event-detail modal (used on `/sfm`, `/unit/{id}`, `/admin/events`, and `/projects/{p}/nrl/{l}`) gains a Chart.js waveform/histogram chart, inline PDF preview, original `.TXT` download, and a review form with false-trigger flag + reviewer + notes.  `/admin/events` finally gets the modal too.  A new Settings field controls the mic chart's display unit.
+
+### Added — Event-detail modal: Chart.js waveform/histogram panels
+
+- **4-channel stacked plots** (MicL → Long → Vert → Tran, matching BW Event Report layout) inside the existing `partials/event_detail_modal.html` shell.  Ported from seismo-relay's standalone `sfm/sfm_webapp.html:2555-2880`; theme-aware grid + tick colors (light/dark mode via Tailwind's `dark` class on `<html>`).
+- **Waveform mode**: line plot, symmetric Y-axis around zero for geo channels, dashed trigger overlay at `t=0` with triangle markers above and below, zero-baseline dashed line + "0.0" label on the right margin.  Downsamples at >3000 samples to keep render time bounded.
+- **Histogram mode**: bar plot, zero-anchored Y with minimum range (`0.05 in/s` geo, `0.001 psi` mic) so quiet events don't fill the panel.  X-axis uses `time_axis.interval_times` (HH:MM:SS labels emitted by seismo-relay v0.20.0+) when available, otherwise falls back to interval index.  Trigger/zero-baseline overlays suppressed (no trigger concept on histograms).
+- **Mic conversion** — converts raw psi samples to dB(L) for the chart when the operator's `mic_unit_pref` is "dBL" (the default).  Rectifies the AC waveform (`abs()`) and floors at `MIC_DBL_FLOOR = 60` so the chart reads as an SPL-vs-time curve instead of a sparse pattern of isolated spikes above the floor.  Peak label uses the unrectified value.
+- **Chart cleanup** — `_destroyCharts()` runs on modal close so repeated open/close doesn't leak Chart.js instances.
+- Chart.js 4.4.1 pinned via cdn.jsdelivr at the bottom of the modal partial; matches the standalone webapp's reference version.
+
+### Added — Event-detail modal: PDF preview + downloads + review form
+
+- **"Show Event Report PDF"** toggle opens an inline iframe inside the modal (no second-layer modal, no new browser tab).  Iframe lazy-loads on first reveal — closing the modal without opening the PDF never spends bandwidth on the fetch.  Sized 80vh / 600px min so a typical letter-portrait single-page report fits with browser-native zoom + download + print controls available.  Companion "Download PDF" button for direct save.
+- **"Original .TXT report"** download link, rendered only when `sidecar.source.txt_filename` is present (events ingested with seismo-relay's `.TXT` preservation pattern, post-2026-05-27).  Hidden for legacy events to avoid 404 dead links.
+- **Inline Review form** — `false_trigger` checkbox + reviewer text input + notes textarea + Save button.  Persists via `PATCH /api/sfm/db/events/{id}/sidecar` with `{review: {...}}`.  Status line shows last-reviewed timestamp + save success/failure feedback.  On save fires a `sfm-event-review-saved` `CustomEvent` on `window` so the host page's table can refresh without a full reload — wired up on `/sfm`, `/unit/{id}`, `/admin/events`, and `/projects/{p}/nrl/{l}`.
+
+### Added — `/admin/events` row click opens the modal
+
+- The SFM Event DB Manager at `/admin/events` previously had no detail view — admins had to copy an event ID and load the standalone webapp on port 8200.  Now table rows are clickable: `onclick` on `<tr>` calls `showEventDetail(id)`, with `event.stopPropagation()` on the checkbox cell so bulk-selection clicks don't also open the modal.
+- `partials/event_detail_modal.html` + `event-modal.js` are now included on this page, matching the existing pattern on `/sfm`, `/unit/{id}`, and `/projects/{p}/nrl/{l}`.
+
+### Added — `mic_unit_pref` user setting (Settings → General)
+
+- **New `user_preferences.mic_unit_pref` column**, "dBL" default with "psi" as the alternate value.  Controls only the event-report modal's waveform chart mic axis — peak values in every other surface (event tables, KPI tiles, modal Peaks section) stay in dB(L) regardless.
+- Surfaced as a single dropdown on Settings → General, below the auto-refresh interval.  Round-trips through `GET/PUT /api/settings/preferences`.
+- New `backend/migrate_add_mic_unit_pref.py` script for existing databases — idempotent ALTER TABLE.
+
+### Fixed — Docker Compose: SFM container can finally read the DB
+
+- `../seismo-relay-prod-snap` is now bind-mounted into the SFM container at the same absolute host path it had outside, so the symlinked `seismo_relay.db` + `waveforms/` directory inside `bridges/captures/` resolve.  Without it, SFM 500'd on every `/db/*` proxy call because the symlink target wasn't visible from inside the container.  Read-write (not `:ro`) because SFM opens the DB in WAL mode, which requires creating `-wal` and `-shm` sidecar files even for reads.
+
+### Migration Notes
+
+```bash
+cd /home/serversdown/terra-view
+# Apply the new column to the database — required.  Idempotent.
+docker exec terra-view-terra-view-1 python3 /app/backend/migrate_add_mic_unit_pref.py
+
+# Rebuild + restart both Terra-View and SFM (compose mounts changed).
+docker compose build terra-view && docker compose up -d
+```
+
+Set Settings → General → "Event Report — Mic Channel Units" if "psi" is preferred over the default "dB(L)".  Setting persists in the DB and is fetched once per modal open.
+
+### What's NOT in this release
+
+Device-control endpoints (`/device/*` — start/stop monitoring, push compliance config, erase events, etc.) remain unexposed in the Terra-View UI.  They proxy through transparently but no page calls them.  Phase 2 of the SFM integration will bring them online once the SFM auth layer lands (a hard prerequisite — anything reachable through Terra-View's URL needs to be gated against unauthenticated callers).
+
+---
+
+## [0.12.1] - 2026-05-20
+
+Field-operations polish — three small features and two correctness fixes that smooth out the deployment workflow added in v0.12.0.  The new Unit Swap wizard and editable deployment timeline are the operator-facing items; the swap/unassign/promote roster-flag fix closes a long-standing data-consistency hole.
+
+### Added — Unit Swap wizard (`/tools/unit-swap`)
+
+- **Mobile-first 4-step wizard** for the common field operation: pick project → pick location → choose incoming unit (with optional modem swap) → review + confirm.  Designed for tap-driven use on a phone in the field; works on desktop too.
+- **Benched-candidate awareness**: `GET /api/projects/.../available-units?include_benched=true` and `available-modems?include_benched=true` now return units/modems with `deployed=False` alongside the active fleet — exactly the inventory a tech pulls off the shelf.  Each row carries a `deployed` boolean for badge rendering.  Default (`include_benched=false`) is unchanged, so the existing location-detail swap modal isn't affected.
+- **`POST /locations/{loc}/swap` enhancements**:
+    - Flips the incoming unit (and modem) back to `deployed=True` if either was on the bench, keeping the legacy `RosterUnit.deployed` flag consistent with the active-assignment signal.
+    - Adds the symmetric half of the orphan-pairing fix: when a newly-paired modem still claims a different seismograph (whose `deployed_with_modem_id` was never cleared in a past swap), the stale back-reference is broken before re-pairing.
+- **`locations-with-assignments`** response now includes `modem.deployed`, so the wizard can badge the current modem in the location card, "Keep current modem" choice, picker rows, and review screen.
+- Tile on `/tools` for discovery; sidebar entry in the Tools nav cluster.
+
+### Added — Editable deployment timeline on `/unit/{id}`
+
+- **Per-row inline edit (pencil icon)** on each assignment in the unit's Deployment Timeline.  Opens a modal with `assigned_at`, `assigned_until` (with an "open-ended" checkbox that clears the end date), and notes.  Saves via the existing `PATCH /api/projects/{pid}/assignments/{aid}`; delete (for misclicks) via the existing `DELETE`.
+- **"+ Add deployment record" button** at the top of the timeline for backfilling historical windows — useful when orphan events sit outside any assignment.  Modal flow: project → location → assigned_at → assigned_until (optional open-ended) → notes.
+- **Closed-window assignments** now accepted by `POST /api/projects/.../locations/{loc}/assign`: the blanket "location already has an active assignment" check became overlap detection against same-location windows.  Closed historical assignments that don't overlap an existing one are accepted (the backfill case).
+- After any save/delete the timeline reloads and the SFM-events list re-fetches, so previously-orphaned events flip to "attributed" when their timestamp now falls inside an assignment window.
+
+### Fixed
+
+- **`RosterUnit.deployed` now flips correctly on swap / unassign / promote-pending** (`POST /locations/{loc}/swap`, `POST /assignments/{aid}/unassign`, `POST /deployments/pending/{id}/promote`).  The legacy `deployed` flag drives heartbeat polling and benched-vs-deployed roster filters; before this fix, those three workflows ended an assignment without flipping the flag, so the outgoing unit kept being polled and showed up as "deployed" forever.  All three now: close the previous active assignment, break the outgoing unit's modem pairing (both directions), and set `deployed = False` on the outgoing unit.  Unassign and swap also clear the modem's back-reference.  Promote-pending additionally handles the case where the target location already has an active assignment — previously this silently created two active assignments at the same location; now the old one is closed (`assigned_until = pending.capture_time`, `status = completed`), the old unit benched + unpaired, and an `assignment_swapped` `UnitHistory` row is written.
+- **Deployment timeline now respects user timezone for display *and* edits.**  Timestamps were stored correctly as UTC but rendered raw — a 1:30 PM EDT swap displayed as "5:30" because the frontend sliced the naive UTC ISO string straight to the screen.  Two-sided fix:
+    - **Display**: `services/deployment_timeline.py` converts every emitted timestamp (`starts_at`, `ends_at`, `event_overlay.peak_pvs_at`, `last_event`) through `utc_to_local()` using the user's configured timezone from `UserPreferences` before serializing.  Frontend slicing keeps working — it just slices a local-time string now.
+    - **Write**: `PATCH /api/projects/{pid}/assignments/{aid}` and `POST /locations/{loc}/assign` interpret a *naive* `assigned_at` / `assigned_until` ISO string as the user's local time and convert to UTC via `local_to_utc()`.  Explicit tz-aware strings (`...Z` or `...+00:00`) skip the conversion, so programmatic callers that already speak UTC keep working.

+## [0.12.0] - 2026-05-17
+
+Field-deployment workflow + fleet-wide deployment views + SFM event DB management.  The headline is the mobile capture flow: a field tech can now arrive on site, take one photo of the installed seismograph, and walk away — classification (which project, which location) happens later at a desk through the new pending-deployment hopper.  EXIF GPS is auto-extracted on capture, so the resulting `UnitAssignment` lands with coordinates without anyone typing them.
+
+### Added — field-deployment workflow
+
+- **`/deploy` — mobile-first 3-step capture wizard**: pick unit → take photo (opens phone camera via `<input capture="environment">`) → optional note → submit.  Designed for under-90-seconds-on-site.  Success page shows captured coords and links back to "Deploy another" or the pending hopper.
+- **`/tools/pending-deployments` — the hopper**: filter pills Awaiting / Assigned / Cancelled.  Each card has photo thumbnail, unit link, coords, operator note, status-appropriate actions.
+- **Classify modal**: two modes — assign to existing project+location, OR create new location with new-or-existing project + a "use captured coords" checkbox that writes the pending row's coords onto the new location record.
+- **`PendingDeployment` data model** (`pending_deployments` table): lifecycle `awaiting → assigned | cancelled`.  Photo file lives under `data/photos/{unit_id}/install_YYYYMMDD_HHMMSS_<uuid8>.<ext>`.  Migration: `backend/migrate_add_pending_deployments.py` (idempotent).
+- **Backend endpoints**:
+    - `POST /api/deployments/capture` — multipart upload (unit_id, photo, optional note), EXIF GPS extraction, seismograph-only (rejects others with 400)
+    - `GET  /api/deployments/pending` — list by status
+    - `GET  /api/deployments/pending/{id}` — single row detail
+    - `POST /api/deployments/pending/{id}/promote` — classify and create `UnitAssignment`; events in the assignment window get retroactively attributed via the existing metadata-backfill mechanism
+    - `POST /api/deployments/pending/{id}/cancel` — abandon with optional reason
+    - `GET  /api/deployments/seismograph-picker` — JSON list for the `/deploy` picker, annotated with `has_pending`
+- **Discovery surfaces**: orange "Field Deploy" button on the desktop dashboard header (md+), bottom-nav slot 3 on mobile (Menu / Dashboard / Deploy / Events; Devices moved into the Menu drawer), `/tools` cards for both Field Deploy and Pending Deployments, dashboard banner that auto-shows when awaiting captures exist (polled every 30s, hides at 0).
+- **Full audit trail**: every capture / promote / cancel writes a `UnitHistory` row (`pending_deployment_captured` / `_promoted` / `_cancelled`).
+
+### Added — fleet-wide deployment history
+
+- **`/tools/deployment-history` — fleet-wide 12-month calendar** (Phase 2 of the per-unit Gantt from v0.11.0).  4-month-per-row grid styled like the Job Planner, responsive to single column on mobile.  Each day cell shows up to 4 deterministically-colored mini-bars (one per active project that day), with "+N" overflow.  KPI strip across the top: project count, distinct unit count, total assignment count in the window.  Collapsible project legend ordered by first-active date.
+- **Click-a-day side panel**: slide-over from the right, groups by project, lists every (unit, location) active that day with auto-backfilled tags, sourced from new `GET /api/admin/deployment-history/day`.
+- **Prev / Next / Recent month navigation**: shifts the 12-month window by 1 month.  Default window is 11 months back from current → operator sees recent past on first load, not future emptiness.
+- **Gantt by Project tab**: horizontal time-axis bars per project, hover for tooltip with unit + location + window.  Reduced opacity for closed assignments, blue outline for metadata-backfilled, today dashed-orange line.
+- **Gantt by Unit tab**: same idea inverted — one row per seismograph, bars colored by project.  Natural for "where has BE11529 been across all my jobs?"  Service layer returns a `units` array with bars carrying baked-in `project_color`.
+- **Tab switcher with hash sync**: `#gantt` / `#byunit` preserved across month-paging.  Tab registry (`_DH_TABS`) makes adding future views a one-line addition.
+
+### Added — SFM event DB management
+
+- **`/admin/events` — SFM Event DB Manager** under Developer Tools.  Cross-unit event browser with filters (serial, from/to, false_trigger, limit), checkbox selection with select-all, and bulk actions:
+    - **Delete selected** — hard-delete chosen rows from SFM's `events` table
+    - **Delete ALL matching current filter** — dry-run first to show match count + sample serials in confirm dialog; only proceeds on explicit confirmation
+    - Same Flag-as-FT / Clear-FT bulk actions for convenience
+- **Destructive operations also clean up on-disk files**: associated `.AB0*` blastware binary, `.a5.pkl`, `.sfm.json` sidecar, and `.h5` files are unlinked alongside the DB row.  Cannot be undone — the manager has a prominent red warning banner and a `max_rows` safety cap (10,000) that refuses oversized deletes without explicit acknowledgment.
+- **Designed for cleaning bogus events from a misbehaving unit** — a stuck-triggered seismograph can dump hundreds of junk events into SFM before it's recovered; this is the operator's broom.
+- **`unit_detail.html` also gains bulk false-trigger flagging**: same checkbox UX as the DB manager, but with **🚩 Flag as false trigger** / **✓ Clear false trigger** instead of delete (delete is admin-only via `/admin/events`).  Concurrent fan-out (8 in flight) for fast bulk PATCH.
+
+### Added — maps, navigation, polish
+
+- **Reusable location-map partial** (`templates/partials/projects/location_map.html`): self-contained map div + self-fetch script.  Accepts `project_id`, `map_height`, `location_type` filter.  Project overview's inline map (~150 lines of JS) replaced with a 1-line include; Vibration tab on the project detail page now uses the same partial with `location_type='vibration'` at 450px height.
+- **Hover location card → highlight matching map pin** on the project overview map.  Enlarges + reddens the pin, opens its tooltip.  Bidirectional with the existing pin → card flash.  Event delegation on `document` so cards from htmx swaps keep the behavior without rewiring.
+- **Mobile bottom-nav swap Settings → Events**: Settings (rarely needed in the field) replaced by Events (the daily mobile destination since the SFM integration).  Settings/Projects/Tools/admin pages still in the Menu drawer.
+
+### Fixed
+
+- **`/deploy` photo input now allows gallery picks**: `capture="environment"` was forcing mobile browsers to open the camera and skip "Photo Library" / "Choose File".  Useful at the install site, problematic when uploading a photo taken earlier.  Attribute removed; chooser now offers both options.  EXIF extraction works identically.
+
+### Migration Notes
+
+One new migration this release.  Idempotent and non-destructive.
+
+```bash
+docker exec terra-view-terra-view-1 python3 /app/backend/migrate_add_pending_deployments.py
+```
+
+Or sweep all migrations at once (safe — already-applied ones no-op):
+
+```bash
+for f in backend/migrate_*.py; do
+  docker exec terra-view-terra-view-1 python3 "/app/backend/$(basename $f)"
+done
+```
+
+New table: `pending_deployments` — capture rows for the field-deployment workflow.  Empty after migration; populated as field techs use `/deploy`.
+
+**Deploy order matters**: run the migration BEFORE the new code is up, or the running app will 500 on the missing table.  Same gotcha that bit the v0.10.0 → v0.11.0 deploy.
+
+**SFM bump pairing**: this release pairs with seismo-relay v0.17.0, which adds the `DELETE /db/events/{id}` and `POST /db/events/delete_bulk` endpoints that `/admin/events` consumes.  An older SFM will return 405/404 for those routes; the manager will surface the error in its result alert.
+

 ## [0.11.0] - 2026-05-15
 
 Operator-facing polish release.  All work builds on the v0.10.0 SFM integration foundation — this release is about making the day-to-day workflows (managing locations, cleaning up bad attributions, browsing deployments) faster and less error-prone.

+Migration: add `pending_deployments` table.

+Stores "I just installed this seismograph" captures from the field.
+A pending deployment is the prospective form of a UnitAssignment —
+captured at install time (photo + coords + maybe a free-text note),
+classified later (project + location chosen at a desk).
+
+Once classified, a real UnitAssignment is created, the pending row's

+# Client Portal — Design & Build Plan
+
+**Status:** in development (`feat/client-portal`) · **Targets:** 0.14.x
+
+A client-facing, **read-only**, **scoped** view into a client's own monitoring
+data. The first internet-facing-with-real-clients surface in the system. Built
+*inside* the Terra-View app (new `/portal/*` namespace), reusing the cached SLMM
+reads and Terra-View's report generation — Terra-View stays the UI/business layer;
+SLMM stays the device layer.
+
+## Principles
+
+1. **Read-only.** No device control (start/stop/config), no roster editing, no
+   internal pages. A client can look, never touch.
+2. **Strictly scoped.** A client only ever sees data for *their* projects. Every
+   portal endpoint verifies ownership server-side — never trust a `unit_id` /
+   `location_id` from the request.
+3. **Cache-first, no device contention.** Portal live data comes from SLMM's
+   cache (the same cached `/status` + `/history` the internal dashboard uses).
+   No device-hitting calls from the portal — a client can't make us hammer the
+   NL-43. Freshness depends on **keepalive being on** for the client's units.
+4. **Auth is a swappable gate.** Every route depends on one resolver,
+   `get_current_client()`. M1–M3 ride on an interim signed "magic URL"; M4
+   replaces the resolver's backing without touching routes or templates.
+
+## The data chain (how a client maps to live data)
+
+```
+Client.id
+  └─ Project (client_id == Client.id, status != deleted)
+       └─ MonitoringLocation (project_id, location_type == "sound", removed_at IS NULL)
+            └─ UnitAssignment (location_id, status == "active", device_type == "slm",
+                               assigned_until IS NULL or future)
+                 └─ unit_id  ==  RosterUnit.id  ==  SLMM unit_id
+                      └─ SLMM cached /status + /history   (read-only)
+```
+
+So the portal shows a client their **locations**, each surfacing the live sound
+level from whatever SLM is currently assigned there.
+
+## Data model (new)
+
+```python
+class Client(Base):                       # the customer org
+    id, name, slug (unique, URL-safe), contact_email (nullable, for M4),
+    active (bool), created_at
+
+class ClientAccessToken(Base):            # the interim "magic URL" gate
+    id, client_id, token_hash (sha256 — raw shown once on creation),
+    label, created_at, last_used_at, revoked_at (nullable)
+```
+
+Plus a migration adding **`Project.client_id`** (nullable FK → `clients.id`).
+The existing free-text `Project.client_name` stays for display/back-compat;
+`client_id` is the authoritative link.
+
+## Auth — the swappable gate
+
+```python
+def get_current_client(request, db) -> Client:   # every /portal route depends on this
+    # M1–M3: read signed `portal_client` cookie -> load Client
+    # M4: same signature, backed by real sessions (magic-link / password)
+```
+
+**Interim "magic URL" flow (M1–M3):**
+- Operator creates a `Client` + an access token → gets a one-time-display URL:
+  `https://…/portal/enter/{token}`.
+- Client clicks it → token is hashed, looked up (must be un-revoked) →
+  sets a **signed session cookie** (`portal_client`, HMAC via a new `SECRET_KEY`
+  env) → redirects to `/portal`. `last_used_at` updated.
+- `get_current_client` reads + verifies the cookie thereafter. No valid cookie →
+  "link invalid / expired" page.
+- Revoke = set `revoked_at`; the link (and any cookie minted from it) stops working.
+
+Unguessable + revocable + per-person, no email infra or passwords yet — and M4
+slots in behind the same `get_current_client` with zero route/template churn.
+
+## Routes (`/portal/*`)
+
+| Route | Purpose |
+|-------|---------|
+| `GET /portal/enter/{token}` | validate token → set cookie → redirect to `/portal` |
+| `GET /portal` | client's locations overview (status tiles + map) |
+| `GET /portal/location/{id}` | read-only live panel for that location's SLM |
+| `GET /portal/api/location/{id}/live` | **scoped** cached `/status` for the location's unit |
+| `GET /portal/api/location/{id}/history` | **scoped** cached trail for the chart |
+| `GET /portal/logout` | clear cookie |
+
+**Scoping helper** (used by every data route):
+`resolve_client_location(client, location_id, db) -> (location, unit_id)` — raises
+403 if the location isn't in one of the client's projects. The portal never calls
+the open `/api/slmm/{unit}/*` endpoints with a client-supplied id.
+
+## Templates (`templates/portal/`)
+
+- `portal/base.html` — minimal client-branded shell (no internal sidebar/nav).
+- `portal/overview.html` — location tiles (live cards mini) + a locations map.
+- `portal/location.html` — the read-only live panel: cards (Lp/Leq/Lmax/L1/L10),
+  L1/L10 chart, measuring + freshness badge. Reuses the cache-populate JS from the
+  internal panel, **stripped** of start/stop, config, and the device-hitting
+  refresh (cache + 15s auto-poll only).
+
+---
+
+## Milestones
+
+### M1 — Live view only  *(current)*
+Interim magic-URL gate; a client sees their locations and per-location read-only
+live data, all from cache.
+- [ ] `Client` + `ClientAccessToken` models; `Project.client_id` migration.
+- [ ] `SECRET_KEY` env + signed-cookie session helper.
+- [ ] `get_current_client` dependency + `/portal/enter/{token}` + logout.
+- [ ] Scoping helper `resolve_client_location`.
+- [ ] `/portal` overview + `/portal/location/{id}` (read-only live panel).
+- [ ] Scoped `/portal/api/location/{id}/live` + `/history`.
+- [ ] Portal templates (base, overview, location).
+- [ ] Minimal admin: create client + mint/revoke access link (small `/admin`
+      page or a script for now).
+
+### M2 — Dashboard + alerts
+- Richer client dashboard (multi-location at-a-glance, status rollup).
+- **Live project map** — upgrade the overview's basic location pins into a real
+  project map: pins colored by measuring/level, popups showing each location's
+  current reading, centered/zoomed to the project. (M1 ships the plain pin map;
+  this makes it a live status map.)
+- Surface each location's **threshold-alert status** (read-only) + an event/inbox
+  view. Leans on the SLMM alert engine + dispatch.
+
+### Notes carried from M1
+- Tile headline metric is **Leq** (energy-average, the sound-monitoring compliance
+  metric) — chosen over the twitchy instantaneous Lp. If clients ever want a
+  different headline (e.g. Lmax for peaks), make it a per-deployment setting.
+
+### M3 — Reports
+- Client-facing list + download of the daily baseline-comparison reports.
+- Depends on the FTP report pipeline (`feat/ftp-report-pipeline`) landing and
+  being wired into the portal's scoped routes.
+
+### M4 — Full auth system
+- Replace the interim token behind `get_current_client` with a real auth design:
+  magic-link (passwordless email) and/or accounts, proper sessions, password
+  reset, and likely auth for the *internal* app too. Reverse-proxy + TLS posture.
+
+## Going to prod (M1)
+
+1. **Run the migration on the prod DB** — `migrate_add_client_portal.py` adds
+   `projects.client_id` (the new tables auto-create via `create_all`). Skipping it
+   500s anything that touches `Project.client_id`. This is the silent killer.
+   ```bash
+   docker compose exec web-app python3 backend/migrate_add_client_portal.py
+   ```
+2. **Set a real `SECRET_KEY`** in the prod env (compose). The portal signs session
+   cookies with it; the insecure dev default (it logs a warning at boot) is
+   forgeable. Non-negotiable for an internet-facing portal.
+3. **SLMM_BASE_URL** — prod base compose already points at `:8100` (correct; the
+   `:9100` mismatch is a dev-only override quirk). For full live data (L1/L10 +
+   chart backfill) prod SLMM must be on the `dev` build with its migrations
+   (`migrate_add_ln_percentiles`, `migrate_add_monitor_enabled`) and **keepalive on**
+   for the client's units — otherwise the portal degrades gracefully (cards show
+   `--`, chart empty), it just isn't fully populated.
+4. **Seed real clients** with the CLI (`backend/portal_admin.py`): `create-client`
+   → `link-project` (a real sound project with an active SLM assignment) →
+   `mint-link` → send the client the printed URL (shown once).
+5. **Exposure** — portal routes are auth-gated, but port 8001 still serves the
+   whole *internal* app with no auth. Before real clients are on it, the portal
+   should sit behind the reverse proxy with only `/portal/*` exposed (or the app
+   restricted). This is the point where the parked reverse-proxy/TLS work becomes
+   load-bearing.
+
+## Security notes
+
+- Portal is auth-gated from day one (even the interim gate) — never wide-open like
+  the internal app.
+- All scoping enforced server-side; client-supplied ids are always re-checked.
+- `SECRET_KEY` must be a real secret in prod (env, not committed).
+- Cookies: `HttpOnly`, `SameSite=Lax`, `Secure` once behind TLS.
+- Tokens stored hashed; raw shown once. Revocation is immediate.
+
+## Security hardening backlog ("Fest 2026")
+
+The to-do for the dedicated hardening pass, roughly highest-impact first. Until
+then the portal runs on security-by-obscurity (open port + interim links) — fine
+for a not-in-use demo, not for real clients.
+
+**Exposure (the big one):** port 8001 serves the *entire operator app* (roster,
+projects, `/admin/*`, device config, the SLMM proxy) with **zero auth**, so an
+open port exposes far more than the read-only portal.
+- [ ] Reverse proxy (NPM/Caddy/Nginx) in front, exposing **only `/portal/*`** to
+      the internet; keep the operator app reachable on the LAN only.
+- [ ] TLS everywhere (Let's Encrypt). Then set portal cookies `Secure`.
+- [ ] Don't port-forward the raw app; if a quick gate is wanted before M4, an
+      auth proxy (Authelia / Authentik) can front the portal without writing auth.
+
+**Config musts:**
+- [ ] Set a real `SECRET_KEY` env (signs session cookies; default is public).
+- [ ] `PORTAL_OPEN_LINKS=false` in any internet-facing env (it defaults off now).
+
+**M4 — real auth** (replaces the interim token behind `get_current_client`):
+- [ ] Magic-link email and/or accounts; proper sessions + password reset.
+- [ ] Authenticate the **operator** app too (it currently has none).
+- [ ] Gate the operator-only endpoints that are presently unauthenticated:
+      `/projects/{id}/portal-preview`, `/projects/{id}/portal-link*`,
+      `/portal/open/*`.
+
+**Smaller items from the pre-merge code review:**
+- [ ] Keepalive isn't auto-turned-off when the last alert rule on a unit is
+      deleted (intentional "never auto-off"; revisit if it wastes cellular).
+- [ ] Consider rate-limiting the scoped portal endpoints once public.

+# Terra-View Roadmap
+
+Living document — captures known deferred work, in-flight initiatives, and longer-term ideas.
+Bump items up/down or strike them through as priorities shift. Source of truth for "what's next"
+should be this file plus the `## Current Development Focus` block in `CLAUDE.md`.
+
+Last updated: 2026-06-05 (Terra-View v0.13.3)
+
+---
+
+## In Flight
+
+Work that's started or has obvious next steps in the code.
+
+- **SFM Integration Phase 2 — device control** — expose `/device/*` (start, stop, erase, push-config)
+  through the Terra-View proxy. Blocked on SFM growing an auth layer; placeholder TODOs already in
+  `backend/services/device_controller.py` (lines 73, 109, 207, 282, 582).
+- **Calibration sync from SFM events** — done in v0.13.x. Daily 03:15 job + Settings "Sync now" button.
+  Future: surface "last sync" timestamp on unit detail; per-unit "sync this one" action.
+- **Synology NAS deployment** — doc lives at `docs/SYNOLOGY_DEPLOYMENT.md`. Need to actually deploy
+  + write up what tripped us up vs. the doc's expectations.
+
+## Near-Term
+
+Concrete things scoped but not started.
+
+- **Migrate GPS coord parse in `photos.py`** — currently writes to dead `RosterUnit.coordinates`
+  field. Should write to the active `MonitoringLocation` instead (matches the location-as-truth
+  refactor done elsewhere). Helper: `backend/services/unit_location.py`.
+- **Phase 3 — drag-to-resize deployment bars** on the fleet-wide deployment-history Gantt
+  (`/tools/deployment-history`). Phase 2 (the calendar + Gantt tabs) shipped in v0.12.0.
+- **Phase 5c — swap-detection daily job** — placeholder card already in `templates/tools.html:162`.
+  Auto-detects unit swaps in the field (BE12345 → BE67890 at the same project+location) from
+  operator-typed metadata. Pairs with a notification inbox.
+- **Geocoding for address strings** — TODO in `templates/dashboard.html:913`. Lets locations without
+  explicit coordinates still appear on maps.
+- **ModemManager backend** — `backend/routers/modem_dashboard.py:279` has a TODO for querying a real
+  modem backend. Currently the modem dashboard is mostly read-only metadata.
+
+## Medium-Term
+
+Bigger features, sketched but not designed in detail.
+
+- **Alerting** — email/SMS for missing units, calibration-expiring-soon, sync failures.
+  README's "Future Enhancements" has had this for a while; would pair well with the existing
+  `UserPreferences` thresholds.
+- **Multi-user auth** — currently single-tenant, no login. Probably the prerequisite for any
+  cloud-hosted multi-customer deployment.
+- **Notification inbox** — central place for swap-detection alerts, sync errors, calibration
+  warnings, FT-flag review queue, etc.
+- **Audit log UI** — `UnitHistory` already records everything; expose a filterable view.
+
+## Long-Term / Wishlist
+
+Speculative. Promote up the list once there's a concrete need.
+
+- PostgreSQL backend for larger deployments (SQLite is fine for now)
+- Advanced filtering / saved searches on roster + events
+- Export roster in additional formats (XLSX, GeoJSON)
+- Public-facing project status pages (read-only, share-link gated)
+- SLM module parity with seismographs — modal-based event/measurement detail similar to SFM modal
+- Weather station / accelerometer / GPS tracker modules (new device-type modules following the
+  SLMM pattern — see `CLAUDE.md` → "Adding a New Device Type Module")
+
+## Done / Reference
+
+For shipped items, see `CHANGELOG.md`. For architecture decisions, see `CLAUDE.md`.
