+## v0.18.0 — 2026-05-19
+
+The "Thor / Series IV ingest adapter" release.  Seismo-relay can now accept event files from Instantel Micromate Series IV (Thor) units alongside the existing MiniMate Plus (Series III) Blastware pipeline.
+
+### Added — Thor (Series IV) IDF ingest
+
+- **`POST /db/import/idf_file`** (`sfm/server.py`) — multipart upload endpoint for `.IDFH` (histogram) and `.IDFW` (waveform) event files plus their `.IDFH.txt` / `.IDFW.txt` ASCII sidecars.  Mirrors the shape of `/db/import/blastware_file`: pairing by filename, optional `serial` query hint, per-file outcome reporting.
+- **`sfm/idf_ascii_report.py`** — parser for Thor's TXT sidecars (verified against 1,014 real-world samples).  Extracts device-authoritative PPV, ZC Freq, Peak Vector Sum, Mic PSPL, calibration date, firmware version, sensor self-check results, and project/client/operator strings.
+- **`WaveformStore.save_imported_idf()`** (`sfm/waveform_store.py`) — stores Thor binaries verbatim in `<root>/<serial>/<filename>`, writes a `.sfm.json` sidecar with `source.kind = "idf-import"` and the full parsed report under `extensions.idf_report`.  Reuses the existing `events` table — Thor events dedupe on (serial, timestamp) and surface in `/db/events` alongside BW events.
+- **`tests/test_idf_ascii_report.py`** — parser tests against the `thor-watcher/example-data/` corpus.
+
+### Changed
+
+- `event_to_sidecar_dict()` (`minimateplus/event_file_io.py`) allow-list for `source_kind` now includes `"idf-import"` so the existing sidecar machinery can carry Thor imports.
+- Bumped `pyproject.toml` version to `0.18.0`.
+
+### Companion release
+
+This release ships alongside **thor-watcher v0.3.0**, which adds the SFM forwarder that targets the new `/db/import/idf_file` endpoint.  Operators flip the switch in thor-watcher's new "SFM Forward" Settings tab; events POST to seismo-relay just like the series3-watcher BW forwarder does today.

 ## v0.17.0 — 2026-05-17
 
 The "field rescue + DB management" release.  Hardened against units that are stuck in a runaway call-home loop, and added an operator-facing path for purging bogus events that those same units dump into the DB before recovery.  All work in this release was driven by the BE9558H incident (full incident log + recovery procedure at `docs/runbooks/wedged_unit_recovery.md`).
