Both sides carry content that must survive. The HEAD side documents GET /a2a/threads and GET /a2a/threads/{thread}/messages, and it documents the since epoch validation that returns 400 below 1e9. The feature side documents the new POST /a2a/import. Dropping either side loses accurate documentation, because all of those routes exist: _handle_a2a_thread_messages is defined at Line 1733, _parse_since is applied at Lines 1647 and 1691, and /a2a/import is dispatched at Line 1040.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
The 30 second default timeout is too short for a batch import.
_run delegates to _request_json, which calls urlopen(req, timeout=self._timeout). self._timeout defaults to 30 seconds.
A historical import posts an entire message batch in one request. The server writes every row and, unless defer_index is set, embeds every body before it responds. A realistic chat-history migration exceeds 30 seconds.
On timeout urlopen raises a socket timeout. _request_json catches only urllib.error.HTTPError, so the timeout propagates unwrapped. The server continues processing the batch after the client gives up, so the caller cannot learn imported, skipped, first_id, or last_id.
Re-running the import is safe because it is idempotent on (source, source_id). The caller still loses the result of the first attempt.
Accept a per-call timeout override for this method so callers can scale it with the batch size.

Validate refs and blocks before import.
The loop validates from, thread, body, source_id, ts, and reply_to_source_id. It does not validate refs or blocks, yet both are stored verbatim in the archive payload at Lines 992-995.
The live send path applies stricter rules. _handle_a2a_send in taosmd/http_server.py (Lines 1520-1547) requires refs to be a list of objects, caps it at _A2A_MAX_REFS, requires each kind to be in _A2A_REF_KINDS, requires blocks to be a list of objects, and caps the serialized message at 64KB.
Imported messages are read back by a2a_feed and a2a_thread_messages and echoed to the same consumers. A malformed envelope entered through import therefore reaches consumers that expect the validated shape. The archive is append-only, so the bad payload cannot be corrected afterwards.
Apply the same envelope rules in the pre-write validation loop.

A forward reply reference passes validation and then silently loses the link.
The pre-check accepts reply_to_source_id when the target is in batch_ids. It does not check the target's position in ts order.
The insert loop iterates in ascending (ts, position) order and resolves rti through id_map. If the target message has a later ts than the reply, the target is not yet in id_map. The loop then writes reply_to=None (Lines 976-980) and the batch still succeeds.
The result is a silent loss of the reply link in an append-only archive, which cannot be corrected by re-import because the (source, source_id) pair is now present and the message is skipped. The docstring at Lines 887-889 states that an unresolvable id refuses the batch, so the observed behavior contradicts the documented contract.
Reject the forward reference in the pre-check so the failure is loud and the operator can fix the input.

🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift
Imported messages never reach the knowledge graph.
The loop writes each message to the archive and, unless defer_index is set, to the vector store. It does not extract facts into the knowledge graph.
The coding guidelines require fact extraction for conversation turns and require explicit facts to be stored in both the knowledge graph and vector memory. After this import, imported history is recallable by vector search but absent from the knowledge graph, so graph queries and as_of time-travel over imported conversations return nothing.
Route each imported message through process_conversation_turn(...) with the knowledge graph, archive, and vector memory, and let defer_index=True skip that work in the same way it skips embedding.
As per coding guidelines: "After every user message, extract and store facts using process_conversation_turn(...) with the knowledge graph, archive, and vector memory." and "Store explicit facts directly in both the knowledge graph and vector memory when appropriate, using kg.add_triple(...) and vmem.add(...)."
