- **changed** — Observer error messages now display in plain language with recommended actions instead of silent retry loops
- **fixed** — Worker now carries the gateway's error envelope with code, message, action, and url fields from the OpenRouter classifier
- **fixed** — OpenRouter classifier keeps upstream error body text instead of discarding it, and classifies 402 and key limit exceeded errors as quota exhausted without retrying
- **changed** — Observer failure logging now outputs a single line with kind, code, requestId, message, action url, and request id instead of five-line fan-out
- **fixed** — Session-start warning for observer health now displays the error message, action instructions, link, and request id without telling Pro users to edit settings.json
- **fixed** — Observer-health alerting now triggers at session start when observations stop flowing
- **added** — 7-day Pro trial promotion surfaced in session-start banner, per-message banner, first-session welcome hint, installer Next Steps, viewer header, and cursor-hooks docs with attribution links
- **changed** — Session-start warning for observer health now appears for projects that have no memories yet instead of being hidden by the welcome hint

##### Observer errors now tell you what happened and what to do

When the memory observer stops working — most commonly a CMEM Pro allowance that's been used up — claude-mem now says so in plain words, once, with the one thing to do about it. No more silent `OpenRouter upstream error (status 502)` retry loops.

###### Fixes
- **Worker carries the gateway's error envelope** (#3601): the OpenRouter classifier now understands the cmem.ai gateway's `{code, message, action, url, request_id}` errors and, for plain OpenRouter, keeps the upstream body (e.g. `Key limit exceeded … Manage it using <url>`) instead of discarding it. 402 and "key limit exceeded" bodies are classified as quota exhausted and are **not retried**.
- **One log line per failure**: `Observer failed {kind, code, requestId} <message — action url (req id)>` replaces the five-line fan-out.
- **Session-start warning says the right thing** (#3601, #3612): the observer-health warning now shows the message, a `What to do:` line, the link, and the request id — and no longer tells Pro users to edit `~/.claude-mem/settings.json`. It also appears for projects that have no memories yet (previously the welcome hint hid it).
- **Observer-health alerting** (#3538): claude-mem alerts you at session start when observations stop flowing.

###### Pro trial
- **7-day Pro trial surfaced everywhere the viewer URL is shown** (#3613): session-start banner, per-message banner, first-session welcome hint, installer "Next Steps", viewer header, and cursor-hooks docs — one source of truth (`src/shared/pro-promo.ts`) with per-surface `?from=` attribution links to https://cmem.ai/pro.

Pairs with the cmem.ai gateway change (claude-mem-pro #106): honest status codes (402/401/429/503, never 502), a 6-code error taxonomy, and an `x-request-id` on every error.
