Unreleased — v1.5.0

First release of the SFM event forwarder.

Added — SFM event forwarder

• Forward Blastware event binaries (+ paired BW ACH ASCII reports) to an SFM server. When SFM_FORWARD_ENABLED=true and SFM_URL is set, every event binary in the BW ACH watch folder is POSTed as multipart to /db/import/blastware_file along with its <stem>_<ext>_ASCII.TXT partner report (BW ACH convention; manual-export <binary>.TXT is also supported as a fallback). SFM parses the report and indexes the full per-channel stats (PPV, ZC Freq, Time of Peak, Peak Acceleration / Displacement, Peak Vector Sum + time, sensor self-check Pass/Fail, monitor-log timestamps) into a searchable database — no codec decoding required.
• Idempotent forwarding. Forwarded files are tracked by sha256 in a JSON state file (default <log dir>/sfm_forwarded.json, override via SFM_STATE_FILE). Re-scans don't re-POST and the state survives restarts / auto-updates.
• Re-pair on late-arriving TXT. When the watcher forwards a binary alone (_ASCII.TXT partner didn't appear within SFM_MISSING_REPORT_GRACE_SECONDS), the state file records had_report: false. On subsequent scans, the watcher re-checks whether the TXT has since arrived. If yes, the event is re-forwarded with the TXT attached — the SFM server's upsert path refreshes the DB row with the report's device-authoritative peak / project values. Without this, slow-disk or AV-interrupted TXT writes would permanently leave that event with broken-codec peaks in the SFM database. Legacy state-file entries (without the had_report field) default to had_report: true so an upgrade doesn't unexpectedly re-forward existing entries.
• Quiescence + grace-period guards. Files modified within SFM_QUIESCENCE_SECONDS (default 5s) are skipped to avoid forwarding mid-write. If a binary's report partner hasn't appeared after SFM_MISSING_REPORT_GRACE_SECONDS (default 60s), the binary is forwarded alone rather than blocking forever.
• Per-pass rate cap. SFM_MAX_FORWARDS_PER_PASS (default 500) drips first-deploy backfill instead of hammering the SFM server in one burst. At 60-second SFM_FORWARD_INTERVAL_SECONDS cadence that's ~30K events/hour throughput. Set to 0 for unlimited. Scan walks oldest-first so backfill advances chronologically and successive scans reliably progress.
• event_forwarder.py --seed-state CLI mode. Walks the watch folder once, sha256s every in-window event, and marks them all as already-forwarded without POSTing anything. Recommended pre-deploy workflow on machines with a large historical archive — flip SFM_FORWARD_ENABLED=true after seeding and only events that appear from then on get forwarded.
• SFM Forward tab in the Settings dialog with: Forward checkbox, SFM URL + Test button (GETs /health), Forward Interval / Quiescence / Missing-Report Grace / HTTP Timeout / Max Events Per Pass spinboxes, State File entry with Browse... Save-time guard: enabling forwarding without a URL shows a validation error.
• Histogram-aware log clarity. Histogram events (extensions ending in H) don't get auto-exported reports from BW; the log distinguishes that case ((histogram, no report expected)) from a waveform with unexpectedly missing report (no report ⚠).
• README "First-time deployment" section documenting the seed-state workflow + the rate cap as belt-and-suspenders for safe rollout on machines with hundreds of thousands of historical events.
• 31 new unit tests in test_event_forwarder.py covering filename matching, state idempotency, scan logic (quiescence / grace period / max age / already-forwarded / TXT pairing), multipart byte shape, rate cap (oldest-first, cap=0 unlimited, cap=N enforcement), seed-state mode (in-window seeding / max-age skip / end-to-end skip-after-seed / idempotent re-runs), histogram classification, and an end-to-end POST against a stdlib fake server.

Configuration

New [agent] keys (all default-off — existing 1.4.x deployments don't change behaviour on auto-update):

Key	Default	Notes
SFM_FORWARD_ENABLED	false	Master toggle for the forwarder
SFM_URL	empty	e.g. http://10.0.0.44:8200
SFM_FORWARD_INTERVAL_SECONDS	60	Scan-and-forward cadence
SFM_QUIESCENCE_SECONDS	5	Skip files modified in the last N seconds
SFM_MISSING_REPORT_GRACE_SECONDS	60	Forward without TXT after this delay
SFM_HTTP_TIMEOUT	60	Per-request HTTP timeout
SFM_STATE_FILE	<log dir>/sfm_forwarded.json	Override location of the forwarded-sha256 state file
SFM_MAX_FORWARDS_PER_PASS	500	Per-scan cap (0 = unlimited)

Compatibility

• Requires SFM server v0.16+ (the /db/import/blastware_file endpoint that accepts paired _ASCII.TXT reports + the BW-report label normalisation — released alongside this watcher version on the seismo-relay side).

[1.4.4] - 2026-03-17

Removed

• OK_HOURS and MISSING_HOURS config keys and Settings dialog fields removed — unit status thresholds are calculated by terra-view from raw age_minutes, not by the watcher. These fields had no effect since v1.4.2.

[1.4.3] - 2026-03-17

Added

• Auto-updater now logs all activity to the watcher log file ([updater] prefix) — silent failures are now visible.
• Configurable update source: UPDATE_SOURCE = gitea (default), url, or disabled. In url mode the watcher fetches version.txt and the .exe from a custom base URL (e.g. terra-view) instead of the Gitea API — enables updates on isolated networks that cannot reach Gitea. disabled turns off automatic checks while keeping the remote push path (from terra-view) functional.
• New Updates tab in the Settings dialog to configure UPDATE_SOURCE and UPDATE_URL.

Fixed

• Downloaded .exe is now validated before applying: absolute size floor (100 KB), relative size floor (50% of current exe), and MZ magic bytes check. A corrupt or truncated download is now rejected and logged rather than silently overwriting the live exe.
• Swap .bat now backs up the current exe as <exe>.old before overwriting, providing a manual rollback copy if needed.
• Swap .bat retry loop is now capped at 5 attempts — was previously infinite if the file remained locked.
• Swap .bat now cleans up the temp download file on both success and failure.

[1.4.2] - 2026-03-17

Changed

• Tray icon color now reflects watcher + API health rather than unit ages — green=API OK, amber=API disabled, red=API failing, purple=watcher error.
• Status menu text updated to show Running — API OK | N unit(s) | scan Xm ago.
• Units submenu removed from tray — status tracking for individual units is handled by terra-view, not the watcher.
• Unit list still logged to console and log file for debugging, but no OK/Pending/Missing judgement applied.
• watcher_status field added to heartbeat payload so terra-view receives accurate watcher health data.

[1.4.1] - 2026-03-17

Fixed

• config.ini now saves to AppData\Local\Series3Watcher\ instead of Program Files — fixes permission denied error on first-run wizard save.
• Config path resolution in both series3_tray.py and series3_watcher.py updated to use sys.frozen + LOCALAPPDATA when running as a PyInstaller .exe.
• Status menu item now uses a callable so it updates every time the menu opens — was showing stale "Starting..." while tooltip correctly showed current status.
• Settings dialog now opens in its own thread — fixes unresponsive tabs and text fields while the watcher loop is running.
• Tray icon reverted to plain colored dot — custom icon graphic was unreadable at 16px tray size. .ico file is still used for the .exe file icon.

Changed

• Terra-View URL field in settings wizard now accepts base URL only (e.g. http://192.168.x.x:8000) — /api/series3/heartbeat endpoint appended automatically.
• Test Connection button now hits /health endpoint instead of posting a fake heartbeat — no database side effects.
• "terra-view URL" label capitalized to "Terra-View URL".
• Default log path updated to AppData\Local\Series3Watcher\agent_logs\series3_watcher.log.
• Installer now creates agent_logs\ folder on install.
• BUILDING.md added — step-by-step guide for building, releasing, and updating.

[1.4.0] - 2026-03-12

Added

• series3_tray.py — system tray launcher using pystray + Pillow. Color-coded icon (green=OK, amber=Pending, red=Missing, purple=Error, grey=Starting). Right-click menu shows live status, unit count, last scan age, Open Log Folder, and Exit.
• run_watcher(state, stop_event) in series3_watcher.py for background thread use by the tray. Shared state dict updated on every scan cycle with status, unit list, last scan time, and last error.
• Interruptible sleep in watcher loop — tray exit is immediate, no waiting out the full scan interval.

Changed

• main() now calls run_watcher() — standalone behavior unchanged.
• requirements.txt updated to document tray dependencies (pystray, Pillow); watcher itself remains stdlib-only.

---

[1.3.0] - 2026-03-12

Changed

• Renamed program to "series3-watcher" and main script to series3_watcher.py — better reflects what it does (watches for activity) rather than implying active data emission.
• Default SOURCE_TYPE updated to series3_watcher.
• Default log filename updated to series3_watcher.log.

---

[1.2.1] - 2026-03-03

Changed

• Changed the name of the program to "series3-agent", this was done to align with the s4/thor agent and because it represents the program's functionality better.
• All instances of "emitter" changed to agent.
• config.ini added to .gitignore, replaced with a template example file.
• README.md updated to reflect changes.

---

1.2.0 - 2025-12-04

Changed

• Removed roster CSV dependency and all Dropbox refresh/hot-reload logic; heartbeat now only enumerates .MLG files.
• Added MAX_EVENT_AGE_DAYS filter to ignore stale events and log when no recent activity exists.
• Simplified heartbeat output/logging to show detected units only; logging hardened to never crash the agent.

---

1.1.1 - 2025-12-02

Added

• Example config.ini now ships with API heartbeat settings enabled (API_ENABLED, API_URL, API_INTERVAL_SECONDS, SOURCE_ID, SOURCE_TYPE).

---

1.1.0 - 2025-12-01

Added

• Standardized SFM telemetry payload builder and periodic HTTP heartbeat POST via urllib.
• Config support for API heartbeat (API_ENABLED, API_URL, API_INTERVAL_SECONDS, SOURCE_ID, SOURCE_TYPE); payload includes file path/size metadata.

Changed

• Refactored scanner to retain file paths and header sniff cache; reformatted logging/ANSI handling.

---

1.0.1 - 2025-11-20

Added

• API_URL config key and report_to_server per-unit POST hook (adds requests dependency).

Changed

• Example config.ini roster URL updated; merged into main.

---

1.0.0 - 2025-11-17

Added

• Automatic roster refresh from Dropbox at a configurable interval (ROSTER_REFRESH_MIN_SECONDS).
• Hot-reload of roster file without restarting the script.
• Failsafe reload: if the new roster is missing or invalid, the previous good roster is retained.
• Atomic roster downloads (temp file in-place replace) to avoid partial/corrupted CSVs.
• Startup config echo printing WATCH_PATH, ROSTER_FILE, and ROSTER_URL visibility.
• Active / Bench / Ignored unit categories for clearer fleet status mapping.

Fixed

• Removed stray note=note_suffix bug in the Unexpected Units section.
• Removed duplicate import time.
• Removed duplicate roster load during startup (roster now loads once).
• Cleaned indentation for Python 3.8 compatibility.

Changed

• Reset versioning from legacy v5.9 beta to v1.0.0 (clean semver baseline).
• Main script normalized as series3_emitter.py (later renamed to series3_agent.py in v1.2.1).
