---

- **added** — Added `observed_model` and `observed_billing` fields to telemetry to track the model and billing tier being observed in user IDE sessions
- **added** — Added `observed_model` and `observed_billing` nullable columns to the `sdk_sessions` storage table (schema version 50)
- **fixed** — Fixed `ide` and `provider` fields not reaching PostHog on the `observer_turn_rollup` event
- **changed** — Updated telemetry privacy controls to read only `oauthAccount.organizationType`, `oauthAccount` presence, and `customApiKeyResponses.approved` from `.claude.json` and project parsed objects to those fields immediately
- **changed** — Updated telemetry scrubber whitelist and documentation to include the new `observed_model` and `observed_billing` properties
- **changed** — Improved Stop hook performance to read the transcript once for both the last assistant message and observed model instead of separately

##### What's new

###### Telemetry: observed model, source, and billing tier (#3836)

PostHog previously only knew the *observer* model (the model claude-mem uses to write observations). The `observer_turn_rollup` event now also reports the session being observed:

- **`observed_model`** — the model the user's IDE session is running (e.g. `claude-fable-5-1`), read from the transcript's last assistant entry on each Stop hook.
- **`observed_billing`** — a closed, low-cardinality enum: `max | pro | team | enterprise | subscription | api_key | bedrock | vertex | foundry | unknown`, detected in the hook process from Claude Code's environment and `~/.claude.json`'s `oauthAccount.organizationType`.
- **`ide`** and **`provider`** now actually reach PostHog on the rollup. The docs already claimed this; the rollup computation was dropping them.

###### Storage

- `sdk_sessions` gains two nullable columns, `observed_model` and `observed_billing` (schema version 50). The migration is idempotent and runs on worker start.

###### Privacy

- Only `oauthAccount.organizationType`, `oauthAccount` presence, and `customApiKeyResponses.approved` are read from `.claude.json`, and the parsed object is projected to those fields immediately. Parse failures log only the error class name, never the message.
- Both new properties are whitelisted in the telemetry scrubber and documented in `docs/public/telemetry.mdx`.

###### Performance

- The Stop hook now reads the transcript once for both the last assistant message and the observed model (previously one read; the new field did not add a second).
