Reverses the seam-2-only design from the prior commits on this branch.
Queued user messages arriving DURING a tool batch (Seam 1) splice into
the last tool result's envelope as ``UserInterjection`` advisories via
``wrap_tool_result``. Messages arriving BETWEEN turns (Seam 2) drain
as a single trailing user row via ``_flush_queued_messages`` with
``user_feedback`` (operator text alongside an approval, e.g. "y, use
full path") folded in as a prefix. Cancel/exception drains (Seam 3)
keep the existing ``_flush_queued_messages()`` call unchanged.
Why all three seams:
* Strict-template providers (Mistral, Llama via vLLM with stock chat
templates) reject role-alternation violations. A literal ``user``
row mid-tool-batch breaks ``assistant(tool_calls) → tool → ... →
assistant``; back-to-back ``user → user`` rows on the wire also fail.
* The seam-2-only design produced back-to-back ``user`` whenever
``user_feedback`` and queued items both fired — bug-1 from the round-1
review. Folding ``user_feedback`` as a prefix to the queue-drain
collapses the two into one row.
* During-batch arrivals couldn't ride seam 2 — the splice was the only
way to deliver same-turn without violating role alternation.
Storage symmetry:
Tool DB rows now store the wrapped ``output`` (envelope + advisories)
unconditionally — ``self.messages[i]['content']`` and
``conversations.content`` match exactly. List-typed output (image /
structured MCP results) uses ``wrap_tool_result(raw_joined_text,
advisories)`` at save time so the persisted string is anchored on
``<tool_output>\n`` for the replay parser. ``TOOL_RESULT_STORAGE_CAP``
is removed entirely; tools are responsible for bounding their own
output, storage faithfully represents in-memory. Removing the cap
also simplifies the parser — no truncated-envelope edge case.
Replay extraction:
``decorate_history_messages`` (REST ``/history``) and ``_build_history``
(SSE replay, resume, rewind, retry, post-load, rename re-replay) both
call the public ``extract_advisories_from_tool_envelope`` helper to
pull the envelope back into structured ``advisories`` for JS replay.
Both string content and list-typed content (image+queued-message
combo) covered. JS renders extracted advisories as normal user
bubbles after the tool block via the shared ``replayAdvisoriesAfterTool``
helper in ``shared_static/utils.js``.
Wrapper-tag escape and provider splice:
``escape_wrapper_tags`` now encodes pre-existing ``&`` first using an
``&`` sentinel so tool output containing literal entity strings
(documentation viewers, code analyzers, web scrapers returning entity-
encoded markup) round-trips correctly. Both encode and decode helpers
short-circuit on absence of ``<`` / ``&``.
``_apply_reminders_for_provider`` detects already-wrapped content
(string body and list text-part) by ``startswith("<tool_output>\n")``
and skips re-escape so existing envelopes survive intact when a tool
message also carries ``_reminders`` (the queued-message + tool-error
co-occurrence case is now common).
``decorate_history_messages`` runs in ``asyncio.to_thread`` to keep
MB-scale string work off the event loop.
Other cleanup:
* ``_collect_advisories`` delegates the queue drain to a named helper
``_drain_queued_messages_to_advisories`` so the swap-and-clear pattern
lives next to ``_flush_queued_messages``'s identical pattern and the
side-effect is documented at the call site.
* Preamble strings + body marker for ``UserInterjection`` round-trip
detection moved to module-level constants in ``tool_advisory.py``;
imported by ``history_decoration.py`` so a producer-side rephrase
can't silently desync the parser.
* ``_send_with_mocks`` ctxmgr extracted in ``test_session.py`` — the
six new send-driven tests share an 8-deep ``patch.object`` block.
* ``replayAdvisoriesAfterTool`` shared helper in
``shared_static/utils.js``; ``app.js`` and ``coordinator.js`` both
invoke it.
* Dead truncation-pill CSS removed (``.tool-output-truncated`` and
``.coord-tool-truncated``); the JS that added these elements went
away with ``TOOL_RESULT_STORAGE_CAP``.
* Tautological tests (``TestBuildHistoryAdvisoryPropagation``)
replaced with production-realistic round-trip tests built from
``wrap_tool_result(...)`` envelopes — REST and SSE-replay surfaces
pinned to the same wire shape; full DB round-trip pinned end-to-end.
Negative-tested:
* Reverting the prefix-merge in ``_flush_queued_messages`` produces
back-to-back ``user`` rows, breaking
``test_user_feedback_and_queued_coexistence_single_row_with_prefix``.
* Reverting the ``extract_advisories_from_tool_envelope`` call in
``_build_history``'s tool branch leaves the envelope verbatim in
wire content, breaking the round-trip tests.
* Reverting the wrapper-detection in ``_apply_reminders_for_provider``
entity-encodes the existing envelope's literal tags, breaking both
the string-content and list-content envelope-preservation tests.
* Reverting the ``wrap_tool_result(raw_text, advisories)`` projection
at the DB save site produces a string starting with the original
raw text, breaking
``test_tool_db_row_round_trips_list_output_with_advisories``.
Tests: 5918 passed, 3 deselected. Lint + format + mypy clean on
touched files.
