 All notable changes to `mostlyright`. The format follows [Keep a Changelog](https://keepachangelog.com/en/1.1.0/); the project follows [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
 
+## [1.10.0] — 2026-06-21 — CWOP adapter (PWS live stream + backtest cache)
+
+Adds the **Citizen Weather Observer Program (APRS-IS) adapter** (`mostlyright.weather.cwop`) as a standalone live data source for Personal Weather Stations. Deliberately isolated from the parity-critical core — CWOP data never enters `research()`, `merge/observations.py`, or `live/_sources.py`.
+
+### Added
+- **`mostlyright.weather.cwop` public surface:**
+  - `nearby(icao, *, radius_km, min_count)` — discover nearby CWOP stations from an ICAO anchor
+  - `scan(stations)` — batch single-observation fetch for a station list
+  - `stream()` — async generator yielding live APRS-IS packets
+  - `snapshot(stations, *, persist)` — returns a `schema.cwop.v1` DataFrame; `persist=True` also writes the backtest parquet cache
+  - `latest(station)` — most-recent observation for a single station
+  - `history(station, from_date, to_date, *, qc_status)` — backtest replay from persisted cache, returns `schema.cwop.v1` DataFrame
+  - `persist_observations(observations)` — explicit write path for custom ingestion loops
+- **6-layer QC** — weighted geometric mean (0.0–1.0): range (0.20), temporal consistency (0.20), indoor detection (0.15), buddy/ASOS check (0.20), solar-radiation bias (0.10), reliability (0.15). `< 0.3` → dropped, `0.3–0.7` → flagged, `> 0.7` → clean. History-dependent layers (indoor ≥24 h, solar ≥7 d) pass until enough data accumulates.
+- **Persistence** — monthly parquet at `$HOME/.mostlyright/cache/cwop/{station}/{year}/{month}.parquet` (honors `MOSTLYRIGHT_CACHE_DIR`). `filelock`-guarded read-modify-write merge, dedup by `(station_id, observed_at)` first-seen-wins. No current-month skip (CWOP is ephemeral — unlike re-fetchable AWC/IEM, the current month is the only retention opportunity).
+- **In-house APRS parser** (`weather/_aprs.py`) — MIT-licensed, no GPLv2 `aprslib` dependency; pure stdlib (`socket` + `re`).
+- **`NoCWOPDataError`** — subclass of `NoLiveDataError`; raised instead of returning `[]`/`None`.
+- **`schema.cwop.v1`** — new schema, accepts source tags `"cwop.live"` and `"cwop.cache"` via `_registered_sources`. `schema.observation.v1` `observation_type` enum is untouched (parity firewall).
+- **`[cwop]` extra** — pulls `pandas` for `snapshot()`/`history()` DataFrames.
+
+### Notes
+- **Parity firewall holds.** CWOP is not registered in `research()`, `merge/observations.py` (`SOURCE_PRIORITY`), or `live/_sources.py`. Models access CWOP only through `cwop.history()` — a DataFrame the strategy joins itself, never the settlement join.
+- **Python-only release.** No public TS API surface change; npm packages bump to 1.10.0 in lockstep with no functional change.
+
 ## [1.9.0] — 2026-06-20 — Global NATIVE satellite ring (live path)
 
 Extends the Phase 25 GOES extractor to **entire-world coverage at native-L2 fidelity on the live/self-parse path** — one SDK, no fork. Each instrument family is a distinct, leakage-safe `source` so a model trained on one never silently reconciles against another. The anonymous ring is landed and routed: GOES + Himawari + VIIRS (no key). EUMETSAT Meteosat SEVIRI landed its CGMS projection + OAuth boundary (golden-vector verified, synthetic-fixture-tested) but its **live Data-Store GRIB file reader is a forward seam** — so Meteosat is reachable by explicit `satellite=` and gated out of auto-routing (Europe/Africa falls back to the honest VIIRS fill) until the reader lands. GMGSI mosaic was dropped (lower fidelity, off-brand for a source-identity SDK). Hosted delivery stays a Phase-27 seam.
