Revise PR #327: the carry-forward landed but neither blocker was fixed; ?reader= still overrides the verified token and the archive limit is still missing - #336
Conversation
…tions_feed Carry forward the PR #320 mention feed work unchanged, then fix both blockers: 1. /a2a/mentions now fails closed with 403 when ?reader= does not normalise via _normalise_handle to the verified token sub. The claimed identity is passed to authorize so the signature check is meaningful. A mismatch never leaks the caller's own mentions. 2. a2a_mentions_feed archive query now carries limit=100_000, matching every sibling bus read in service.py. Without it the default 50-row cap silently dropped mentions once the bus exceeded 50 messages. Add two disagreement-control tests: carol's token with ?reader=bob returns 403 and bob's body is absent; a mention remains visible at bus size 120. changelog.d/tsk-mxjvnb-mentions-auth-and-limit.md

📝 WalkthroughWalkthroughAdded an SQLite-backed mention index and A2A mentions feed. The feed supports normalized handles, timestamp and limit filters, same-thread replies, remote access, and authenticated HTTP requests with reader validation. ChangesA2A mentions feed
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟠 High · up to The current change can still expose mention content to principals whose access grant was removed, omit valid or recent mentions, and fail to record recipient mentions sent through HTTP or remote paths; an authentication failure may also return 500 instead of 403. These are concrete security and correctness risks that should be fixed before merging. Sequence Diagram(s)sequenceDiagram

The mentions endpoint skips the grants check.
Every peer path pairs identity with permission. _handle_a2a_send calls _grants_verifier.has_grant(from_) at line 1602, and _apply_token_binding calls has_grant at line 945 for the data endpoints. _handle_a2a_mentions verifies the token and the reader match, then serves message bodies without asking whether the principal holds an active grant.
The effect: a principal whose grant was removed, but whose token is still valid and unrevoked, can keep reading mention content. Add the grant check after authorize succeeds, and skip it for human principals as _handle_a2a_send does.

_ra can be unbound when the except _ra.AuthError clause runs.
from . import registry_auth as _ra sits inside the try block at line 1692, and the except Exception at line 1697 swallows any failure. If that import fails, execution continues with _ra unbound. Line 1703 then raises NameError while handling an auth failure, and the request returns 500 instead of 403.
Move the registry_auth import above the try block. Only the jwt decode needs the broad except.
Also add # noqa: PLC0415 to the from .mentions import _normalise_handle import at line 1707, to match every other function-level import in this file.

The mention query returns the oldest mentions, not the newest.
get_mentioned_message_ids orders by ts ASC and then applies LIMIT. When a reader has more mentions than limit, the query always returns the oldest ones. The newest mentions stay unreachable unless the caller supplies a since cursor. Sibling bus reads take the most recent N rows and then present them oldest-first (see a2a_feed in taosmd/service.py lines 552-559).
Select the newest N rows and reverse them, so the feed shows recent mentions by default.

The final slice can drop mentioned messages.
limit is applied twice: once in get_mentioned_message_ids at line 977 and again at line 1043 after reply-chain expansion. Reply rows share the same budget as mention rows. When a mention thread has many replies, the trailing entries of result are cut, so a mentioned message can be absent from the response even though it matched.
Note that changelog.d/tsk-6icvd4-mentions-feed.md line 5 states that limit is applied once. Align the code and the changelog: either cap only the mention rows and return their full chains, or document that limit caps total returned rows.

twice, causing expanded reply chains to truncate matched mention messages.
Update get_mentioned_message_ids and the surrounding result construction so
limit is applied only once to the mention rows while returning their complete
reply chains, and keep changelog.d/tsk-6icvd4-mentions-feed.md consistent with
that behavior.

can_read ignores all of its arguments and always grants access.
The function is exported in __all__ and reads as a read guard, but it returns True for every input. reader, msg, and data_dir are unused. A future caller can adopt it and get no enforcement.
The docstring states the intent, which is good. Two suggestions:
- Add the mention-grant half now, using
mentions_store.get_mention_recipientsplus_find_thread_root, and leave onlychannelACLas the always-true slot. - If the stub must land as-is, mark it with an explicit
TODO(tsk-dp6fyv)so it appears in the tracked debt list.
Do you want me to draft the mention-grant implementation?

WARNING: root_threads is computed but never used — dead code left from refactor.
The set comprehension on this line assigns to root_threads, but the variable is never referenced. The actual thread-root mapping is built later as thread_roots. This looks like a refactor artifact.
Consider removing this line, or if the intent was to seed reply_chain_ids with thread scoping, wire it into the BFS below.

WARNING: limit=True passes validation — bool is a subclass of int in Python.
isinstance(True, int) # -> True

SUGGESTION: get_mention_recipients is defined but never called in this PR.
This new method is not referenced anywhere in the changed code. It may be intended for future use, but shipping dead code adds maintenance surface. Either wire it into the mentions flow or defer it to a follow-up.

Suite 1591 passed, 12 skipped -- reconciles as baseline 1561 + the 30 tests this PR adds. STATED LIMITATIONS. - test_http_mentions_reader_mismatch_returns_403 passes on #336's implementation too, so it is a regression guard, not evidence the 403 blocker was fixed. The one discriminating arm is reader_normalised_handle_accepted. - taosmd/mentions.py:12 imports math and never uses it. Inherited, not introduced: mentions.py is byte-identical between #336 and this PR (md5 a8b1f088). No linter exists in the repo to catch it. Carded as tsk-vxgjzp rather than blocking correct work. - ?reader= supplied as an empty string reaches authorize() as claimed=raw_sub and is then rejected at the mismatch check. It errs toward 403, so not a hole, but the two paths disagree about what an empty reader means. - Not tested against a production registry verifier; the fixture starts a real HTTP server on a real port with real tokens, which is feature-level but not production evidence.

CARD TITLE (intent, not commit subject): Revise PR #327: the carry-forward landed but neither blocker was fixed; ?reader= still overrides the verified token and the archive limit is still missing
Autonomous build of board card tsk-mxjvnb.
Carry forward the PR #320 mention feed work unchanged, then fix both
blockers:
/a2a/mentions now fails closed with 403 when ?reader= does not
normalise via _normalise_handle to the verified token sub. The
claimed identity is passed to authorize so the signature check
is meaningful. A mismatch never leaks the caller's own mentions.
a2a_mentions_feed archive query now carries limit=100_000, matching
every sibling bus read in service.py. Without it the default 50-row
cap silently dropped mentions once the bus exceeded 50 messages.
Add two disagreement-control tests: carol's token with ?reader=bob
returns 403 and bob's body is absent; a mention remains visible at
bus size 120.
