Follow up #205: survive dropped packs, validate pieces, budget beliefs - #207
Conversation
…udget beliefs - Recall builds the chosen scope's pack again when /v1/answer answers 404 for use_pack_id, up to three answers. CortexDB 0.10.4 drops every pack it holds on any successful forget, even in another scope, so a concurrent forget made recall fail (CortexDB live at 9d40d5d). - get and list return a chunked document whole only when every piece agrees on one positive count, each index is below it, and all are present; an unchunked envelope of the same id is the whole body and wins over pieces. - The beliefs read sends max_tokens for each belief it asks for. - The live long-document test is two pieces, so its forget stays inside the request timeout, and after forget it polls fetch until no piece of the item is left. - The spec states the chunking threshold on the envelope as a piece.

Review comments at @crates/tinymemory-integrations/src/cortex/engine/recall.rs:
- Around line 174-175: Update the pack-invalidation retry flow around
`self.pack` and `self.log.answer` so successful retries rebuild citation inputs
from the refreshed packs instead of the original `per_pack`. Ensure citations
exclude items removed by a forget while preserving the existing citation
behavior when no pack is invalidated.
Review comments at @docs/architecture/cortex-wire.md:
- Around line 202-206: The cortex-wire.md document exceeds the 500-line limit.
Move a focused section into a separate Markdown file, replace it with a link,
and add a link to the new document from the nearest README.md while preserving
the section’s content.

- A 404 for use_pack_id now repeats the whole round: every scope's pack is built again and the answer asked from the new chosen pack, so the citations also come from packs read after the drop and cannot cite an item forgotten in between. At most three rounds. - docs/architecture/cortex-wire.md was over the 500-line limit; its "Chunked documents" section is now docs/architecture/cortex-chunks.md.

@coderabbitai review Both threads from your CHANGES_REQUESTED review are fixed in d344303 and resolved: the citations are refreshed (every pack is rebuilt on a dropped pack), and cortex-wire.md is split under 500 lines. |

Run together, one live test's forgets drop the packs another is about to answer from, and load the server enough that forgetting a ~700 KiB document (seconds per ~240 KiB event on CortexDB 0.10.4) outlasted the request timeout. Each live test now holds one async lock for its run, and the long document is back to 24 pages (three pieces, two boundaries).

[stacked on #207] Write events as prose with the envelope in labels; let items opt out of derivation
Summary
Follow-up to #205 (document chunking). #205 merged with its "CortexDB live" job failing at 9d40d5d and 13 review threads open. This PR fixes the cause of that failure and addresses those threads.
Why CortexDB live failed at 9d40d5d.
documents_conversations_and_learnings_round_trip_into_contextgot404 NOT_FOUND "pack_id expired or unknown (60s TTL)"from/v1/answer, well inside the 60 s TTL. On CortexDB 0.10.4, any successful/v1/forgetdrops every pack the server holds, even a forget in an unrelated scope. This reproduced 3 of 3 times with curl: build a pack, forget one event elsewhere, anduse_pack_idreturns 404, while a fresh pack answers 200. Recall builds packs and then answers from one by id, so it races any concurrent forget. In the live job the conformance test and the long-document test forget while the documents test recalls. Locally, the whole live file failed this way 1 of 4 and 1 of 7 runs on fresh servers. The race is not new in #205 and exists on main, where the post-merge run at cc281d1 passed.Related issue

API or behavior changes
No public API change. Behaviour:
/v1/answeranswers 404 foruse_pack_id, the whole round repeats: every scope's pack is built again, the chosen pack is re-picked, and the answer is asked from it. Answer and citations therefore both come from packs read after the drop, so a citation cannot name an item forgotten in between. At most three rounds; a third 404 is returned asError::NotFound. One retry was not enough under the live suite's forget churn: two forgets landed in two consecutive windows in 1 of 8 runs.get/listcheck the piece layout. A chunked document is returned whole only when every piece agrees on one positivecount, every index is below it, and all of0..countare present.max_tokens = whole_items_budget(limit), like every other pack.Validation

The ~700 KiB document's forget also timed out once in 8 runs while the other live tests loaded the server. The live tests now run one at a time, and the test keeps its ~700 KiB, three-piece document; the comment explains why it stays under 1 MiB.
