Every other entry IS persisted and restored on reopen. Use `maxAge` to bound how long an entry may live while it is queued — that is the field the drain enforces. Note that an ephemeral entry's content still reaches the transcript once it is actually injected into a turn, so this bounds the QUEUE's durability, not the conversation's. **Constraints** (400 on violation): - `source`: ≤64 chars, no control characters or newlines; whitespace-trimmed (a padded label and its bare form share one per-source cap bucket) -- `maxAge`: must be a finite positive number (rejects boolean, NaN, Infinity, ≤0); omit or pass null for no expiry +- `maxAge`: must be a finite positive number (rejects boolean, NaN, Infinity, ≤0). Omit or pass null for no per-entry expiry — subject to a **queue-level backstop of 7 days**, which exists because a full queue now refuses rather than evicting: without it a slot holding no-`maxAge` entries that never takes another turn would answer 429 on every later post forever. - `content`: must be a non-empty string, ≤40,000 chars +**Queue capacity** (429 on refusal, `code: "context_not_queued"`): +- The 429 covers two causes: the queue cannot fit the entry, or the entry's own `maxAge` elapsed between validation and queueing (possible only with a sub-second TTL, since both happen inside one request). The response wording says "could not be queued" rather than naming a full queue, because the second cause refuses with the queue empty — retrying after a drain would not help there, whereas splitting the content or lengthening the TTL would. +- **A 200 means ACCEPTED, not yet on disk.** An entry posted and then lost to a crash before the next save is possible — the same best-effort durability every other slot mutation has. What makes it survive an ordinary tab close and a gateway restart: queuing an entry marks the slot dirty and satisfies the flush's message-less guard, so the **periodic** flush writes a tab holding nothing but queued context; the **shutdown** flush persists a message-less slot outright; and the tab-close path forces a durable save of its own. Neither path drops the queue: both the flush guard and the save's own early return require an empty queue as well as an empty window, so a queued entry keeps the save running through to the write. Durability is bounded by what one session metadata line can carry — an entry that does not fit alongside what is already queued (including the context halves of held notes, which are promoted later) is REFUSED rather than accepted and dropped at save time, because a refusal is visible and retryable whereas silent truncation after a 200 is neither. +- Retry after the next user turn drains the queue, or split the content into smaller entries. The queue is bounded on BOTH dimensions: roughly one worst-case 40,000-char entry by bytes, and 50 entries by count. Reaching either ceiling refuses the new entry — an already-accepted entry is never evicted to make room. +- `/note` does not 429 here.

When the source's per-source context cap is full the request is **not** rejected: the visible line is still written and `contextSkipped` is true, because the cap protects the context queue rather than the transcript. If a turn is already running the note is held until that turn ends -- `appended` is false and `visibleDeferred` is true -- so that it lands on the next turn rather than the one it was written during. Ordering is preserved, and `deliveryConditional` is true whenever a note is held -- because a hold is delivered only if the slot still routes to the SAME session when the turn ends. An unbound slot can acquire a foreign binding while the note waits (a cron result or workflow injection claims an empty `linked_session_key` with no running gate), and both the transcript path and the next turn's session resolve that binding at flush time rather than at the POST. When that happens BOTH halves of the note are dropped rather than retargeted, because writing them would surface content authorized for one conversation inside another; the drop is recorded in the security-event log. So a 200 with `visibleDeferred: true` promises ordering against the running turn, not that the note will certainly be written. `pending` counts held entries as well as queued ones. -**A 200 for a held note is a durable acknowledgement — for a slot that has a durable identity.** The hold is persisted verbatim (both halves, the silent context included) into the slot's own session metadata *before* the 200 is returned, replayed into the hold by both slot-restore paths after a gateway restart, and retired by the save that commits the delivered rows -- so a note accepted with `visibleDeferred: true` survives a restart and is delivered, unaltered, on the first turn after it. Two edges keep the original gateway-lifetime meaning instead: a memory-only deployment (no conversation log at all), and a slot that has never been persisted (no metadata line to attach the hold to -- such a tab does not itself survive a restart, so there is no restored slot the note could outlive). Do **not** re-post a held note after a restart; the restored hold delivers it, and a re-post would put the same line in the transcript twice. Three boundary refusals protect that promise: a note posted during a running turn is capped at 4,000 characters (`413`, code `deferred_note_too_large` -- shorten it or wait for the turn to end), a slot whose durable hold is full answers `429 deferred_notes_full` until its rows are saved, and a slot that is rebound to another session while the hold is persisting answers the endpoint's uniform `404` -- the note was neither delivered nor made durable (a note the turn-end flush drops at that same rebind seam takes this `404` too; the 200 stands only when the note observably exists in a delivered row or the durable hold). The one retry-the-same-request signal is a `503` with code `deferred_note_persist_failed`, which means the durable write itself failed and the note was **not** accepted.

It is persisted into the session's metadata line and re-seated when the session is restored, so it survives closing the tab and survives a gateway restart. `maxAge` continues to run while the session is closed (wall-clock), so a long-closed session does not reopen holding stale background context, and an entry with no expiry comes back for up to seven days (`DEFAULT_CONTEXT_TTL_SECS`), the backstop that bounds a seat the caller never bounded itself. An entry that does not opt in stays memory-only for this gateway lifetime, which is the pre-existing contract; opting in is the deliberate change. + +**Compatibility — a caller that OPTS IN to durability with `ephemeral: false` and re-posts on reconnect will double-inject, unless it also passes `contextKey`.** The old recipe was "if you need a note to survive a restart, re-post it". For an entry that opts in, the restored copy and the re-post both drain into the next user message, so the model sees the content twice. A POST carrying a `contextKey` is refused as a no-op while the first copy is still pending, and a default (memory-only) entry is never restored to be duplicated — so a caller that changes nothing is unaffected. Callers that adopt `ephemeral: false` should drop the re-post, or adopt a key. Re-posting remains the only way to guarantee a *visible* line that was held when the gateway went down. ### Proxy Authentication (Server-side) diff --git a/docs/system-specs/modules/session.md b/docs/system-specs/modules/session.md index 751cf09ed6c..3996fc4b01a 100644 --- a/docs/system-specs/modules/session.md +++ b/docs/system-specs/modules/session.md @@ -825,7 +825,19 @@ state a close compensates is not all scoped the same way. conversation's own MONOTONE once-flags (`auto_tagged`, `human_seen`, `channel_origin`, `channel_folder_filed`) are set and never cleared, so two writers on one transcript cannot disagree about them in a way that outlives the pair; they - stay as written.
