+## [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.

+# FTP Report Pipeline — session brief
+
+**Branch:** `feat/ftp-report-pipeline` (off `dev`), worktree `/home/serversdown/terra-view-reports`.
+**Scope:** Terra-View only. Do NOT touch SLMM — the SLMM alert/monitor work is live in a
+parallel session on `slmm` branch `feat/drd-fix`. Pull device data through the **existing**
+SLMM FTP proxy endpoints; add no SLMM code (for v1).
+
+See memory note `client_sound_monitoring_job_2026-07` for the client requirements + timeline.
+
+## Goal
+Automated **daily morning report** for the John Myler 3-location sound job: each AM, last
+night's noise levels vs the **baseline week**, per location. Data pulled from the meters via
+FTP (the meter records 24/7 to SD regardless of TCP wedges). Alerts are a *separate* workstream
+(SLMM, real-time DOD) — not in scope here.
+
+## The big realization (why this is small)
+The hard parts already exist:
+- **SLMM (use as-is, via the `/api/slmm/...` proxy):**
+  - `GET  /api/slmm/{unit}/ftp/files?path=/NL-43` → list files/folders
+  - `POST /api/slmm/{unit}/ftp/download-folder` → returns the `Auto_####` folder as a **ZIP**
+- **Terra-View ingest (reuse):** `backend/routers/project_locations.py:1743` `upload_nrl_data`
+  already accepts a **ZIP**, extracts, keeps `.rnh` + `_Leq_ .rnd` (drops `_Lp_`/junk via
+  `_is_wanted`), runs `_parse_rnh` (line 1687) → creates `MonitoringSession` + `DataFile`.
+- **Report generator (reuse, source-agnostic):** `backend/routers/projects.py`. The `.rnd`
+  file reads funnel through 3 helpers — `_peek_rnd_headers` (~135), `_is_leq_file` (~147),
+  `_read_rnd_file_rows` (~256). `.rnd` files live on disk under `data/{file_path}` (DataFile
+  holds the path, not a BLOB). The stats/Excel/formatting logic doesn't care where bytes come from.
+
+## Build (Terra-View)
+1. **Refactor** `upload_nrl_data`'s core into a callable `ingest_nrl_zip(location_id, zip_bytes, db)`
+   so it can be invoked programmatically (not only via HTTP UploadFile).
+2. **Scheduled pull job** (reuse the existing scheduler): per project location/unit →
+   `GET /ftp/files` to find new `Auto_####` folders → `POST /ftp/download-folder` (zip) →
+   `ingest_nrl_zip(...)`. **Dedup** so repeated pulls don't duplicate sessions/files
+   (track ingested folder names per location).
+3. **Baseline aggregation:** aggregate the baseline-week `_Leq_` intervals per location →
+   reference values (nighttime Leq, L90 floor, typical Lmax).
+4. **Nightly report + email:** compute last night's metrics per location, compare to baseline
+   (deltas), render (reuse the Excel/report machinery), email each morning.
+
+## Data-location decision (light version, agreed)
+Keep `MonitoringSession`/`DataFile` **metadata in TV** for now; reuse the existing on-disk file
+store. Optional refinement (later): have SLMM keep the pulled files and TV read them through a
+SLMM file-serve endpoint (avoids the copy-into-TV step). Don't do that refinement under the
+deadline unless trivial — the report logic is identical either way.
+
+## Open questions to resolve early
+1. **What's actually in a `_Leq_ .rnd`** — Leq only, or Leq + Lmax + Ln per 15-min interval?
+   Decides whether the night-vs-baseline report can show L90/Lmax or just Leq. Inspect a real file.
+2. **Session rollover / dedup** — does a 2-week run write one growing `Auto_####` folder or new
+   folders? Drives the "what's new" logic.
+3. **`download-folder` over a multi-day run** — confirm it zips cleanly (size/time).
+
+## Client params (confirm with Dave before locking)
+Threshold/metric + their "night" window; report recipients + format (email body vs PDF/Excel).
+
+## Timeline
+Setup ~7/1–7/2 (baseline week), shutdown week through ~7/17. Reports needed by ~7/8 (before
+shutdown). Today is ~3 weeks out — reliability > features.

+  POST …/reports/nightly/run   → full run: build → write report.html/json to
+                                 disk → (dry-run) email.  Returns JSON result.
+
+Dates are the *evening* date of the night being reported (the 7/7 in "night of
+7/7 → morning 7/8").  Defaults to last night.  Baseline is optional; pass the
+baseline-week range to populate the comparison.

+Nightly Report Pipeline — computation core.
+
+Builds the data model for the John-Myler-style "last night vs. baseline" sound
+report.  Source-agnostic: it reads the same on-disk Leq `.rnd` files the manual
+upload + FTP-pull ingest produce (see `project_locations.ingest_nrl_zip`).
+
+Design notes
+------------
+* **Ingest everything, report selectively.**  Ingest preserves every column of
+  the Leq file; this layer chooses which *metrics* to surface via `metric_keys`
+  (a future report wizard is just a UI over that list).
+* **House format match.**  Defaults reproduce the existing Excel report:
+  LAmax (max of interval maxima), LA01 / LA10 (arithmetic average), split into
+  Evening (7–10PM) and Nighttime (10PM–7AM) windows.  L90 (background) is added
+  for the baseline comparison.
+* **Metric labelling from the device.**  The LN→percentile assignment is
+  reconfigurable per job; we resolve which `LNx(Main)` column is L90/L10/etc.
+  from the percentile map captured in the session metadata at ingest, falling
+  back to the NL-43 default order.
+* **Correct averaging.**  Leq is energy-averaged (logarithmic); percentiles and
+  Lmax are arithmetic.  Baseline references combine the per-night values into a
+  "typical night" (arithmetic mean of per-night values — so baseline Lmax is the
+  typical nightly peak, not the worst-of-week).

+# 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

+- **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")

+# FTP Night-Report Pipeline — changelog entry
+
+> **How to use:** paste the block below into Terra-View's `CHANGELOG.md`.
+> The current `[Unreleased]` section targets **0.14.0** (SLM live monitoring); this
+> is a separate, larger feature, so it's drafted here as **0.15.0** — fold it into
+> `[Unreleased]` or bump the version as you prefer. Set the release date when you ship.

+
+## [0.15.0] - 2026-XX-XX
+
+FTP night-report pipeline.  Automated **daily morning report** of last night's noise (7PM–7AM) versus a baseline, per location, for 24/7 remote sound jobs.  The meter records 24/7 to its SD card regardless of TCP state, so the report pulls the meter's own stored 15-minute `_Leq_` intervals over FTP (through the existing `/api/slmm/.../ftp/...` proxy) — accurate Leq/Lmax/Ln straight from the device, and resilient to a TCP-control wedge.  The report engine is source-agnostic and metric-driven; delivery is an HTML email body plus an Excel attachment.  Built around the existing `MonitoringSession`/`DataFile` store and the existing scheduled `cycle` action — the meter is cycled each morning (stop → download → ingest → increment store index → restart), and the report runs off the just-finished, finalized folder.
+
+### Added
+
+- **Callable ingest — `ingest_nrl_zip(location_id, zip_bytes, db)`** (`backend/routers/project_locations.py`).  The manual SD-card upload (`upload_nrl_data`) was refactored into a shared core so the same path runs programmatically from the scheduler.  Keeps `.rnh` + the averaged `_Leq_ .rnd`, drops the 1-second `_Lp_` files, parses the header (now also capturing the device's **percentile→slot map** and weightings into session metadata), and **dedups** repeated pulls of the same folder by store-name + start time.  Metric-agnostic: every column of the Leq file is preserved on disk; metric selection happens in the report layer.
+- **Report compute engine** (`backend/services/report_pipeline.py`).  Per-location night model: **LAmax / LA01 / LA10 / LA90 / LAeq** over **Evening (7–10PM)** and **Nighttime (10PM–7AM)** windows, with correct aggregation — Lmax = loudest interval, percentiles = arithmetic mean, **Leq = logarithmic (energy) mean**.  The LN→percentile mapping is read from the device's own `.rnh` config, not hardcoded.
+- **Two baseline sources.**  *Captured* — computed from recorded nights in a configurable date range (the "typical night" = mean of per-night values).  *Reference* — fixed values typed per location, for a spec limit (e.g. *"L10 = 85"*) or a prior report's averages when the raw data isn't in the system.  Blank reference cells aren't compared.
+- **Renderers** (`backend/services/report_renderers.py`).  HTML email body (per-location Last / Baseline / Δ table, colored louder/quieter) **+ an Excel attachment** — one worksheet per NRL with the 15-minute interval table, a line chart, and a Last/Base/Δ summary per window.  Metric-driven, so it tracks whatever metric set is configured.
+- **Config-driven SMTP sender** (`backend/services/report_email.py`).  Reads host/port/security/user/password/from/recipients from env (`REPORT_SMTP_*`); **dry-run** when unconfigured, so reports still generate and persist without credentials.
+- **Per-project config + automatic morning run.**  New `SoundReportConfig` table (enabled, report time, metrics, baseline mode + range, recipients) and a scheduler tick (`SchedulerService.run_due_reports`) that builds + emails each enabled project's report once per morning, off the event loop.  The orchestrator (`report_orchestrator.py`) always writes `report.html` / `report.json` / `report.xlsx` to `data/reports/{project}/{date}/`, then emails.
+- **Capture hook in the daily cycle.**  `_execute_cycle` now ingests the just-finished `Auto_####` folder into Terra-View after the download, and verifies the meter resumed measuring via a fresh DOD (`measurement_state`) — alerting if not.
+- **UI on the sound project header.**  A **Night Report** button (modal: view a night, *Run & Email* on demand, and a *Recent reports* list with HTML + Excel links) and a **gear → Settings** modal (enable/time, **baseline source toggle** with a per-NRL value editor, metrics, recipients, a **Send test email** button, and a schedule/last-run status line).
+- **Endpoints** (`backend/routers/reports.py`): `GET/PUT …/reports/config`, `GET/PUT …/reports/baseline`, `GET …/reports/nightly/view`, `POST …/reports/nightly/run`, `POST …/reports/test-email`, `GET …/reports/list`, `GET …/reports/archive/{date}` (+ `/xlsx`).
+
+### Changed
+
+- **Manual SD upload now shares the new ingest core.**  `POST …/nrl/{location_id}/upload-data` behaves as before (zip or loose files) but routes through `_ingest_file_entries`, so manually-uploaded sessions also get the captured percentile map.
+
+### Security / hardening
+
+- HTML modal fields built from user-controlled data (location names, baseline values) are HTML-escaped before insertion (stored-XSS fix).
+- The SMTP sender refuses to silently downgrade to a plaintext connection on an unrecognized `REPORT_SMTP_SECURITY` value (falls back to STARTTLS), and warns when credentials would go over an unencrypted link.
+
+### Upgrade Notes
+
+- **No database migration.**  `sound_report_configs` is a brand-new table created automatically by `create_all` on startup (the `baseline_mode` column lives on it).  Templates and Python are baked into the image, so **rebuild** (don't just restart):
+
+  ```bash
+  cd /home/serversdown/terra-view && docker compose build terra-view && docker compose up -d terra-view
+  ```
+
+- **To actually send email**, set the relay env vars (e.g. on the `terra-view` service in `docker-compose.yml`).  Until then, reports still build and write to `data/reports/…` in dry-run:
+
+  ```
+  REPORT_SMTP_HOST, REPORT_SMTP_PORT, REPORT_SMTP_SECURITY=starttls|ssl|none,
+  REPORT_SMTP_USER, REPORT_SMTP_PASSWORD, REPORT_SMTP_FROM, REPORT_SMTP_RECIPIENTS
+  ```
+
+  Use **Settings → Send test email** to verify the relay once set.
+
+- **To turn on automation for a job:** configure a daily `cycle` recurring schedule per NRL (~7:15 AM, after the night ends) so the meter is stopped/downloaded/ingested/restarted, then **enable** the report in the gear (report time ~8 AM) and set the baseline (range or fixed values).
+
+- **Not yet field-tested on a physical meter** — the live device-control portion of the cycle hook (download + restart-verify) was validated against a mocked SLMM only.
