+## [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.
+
+### Migration Notes

 ## [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.
