- _transcript_row_texts re-implemented agent.message_content.flatten_message_text
and the api_content sidecar rule; the note can only land on a user row,
so the transcript scan now skips assistant/tool rows (the bulk of the bytes).
- Three sites computed "names of agent.tools"; tools.mcp_tool_agent gains
agent_tool_names() used by the switch note and conversation_loop, which
also stops importing the private _def_name across modules. The name list
is only captured when a switch was announced.
- split_runtime_boundary() is the single owner of the runtime-block
rpartition/END check for both identity_line_value and
_stored_prompt_matches_runtime.
- platform_surface_hint was a public alias of _platform_hint; the function is
now platform_hint (its docstring pointed at the pre-move module).
- consume_gateway_turn_context_notes and consume_surface_switch_note share
_pop_turn_note so the two one-shot channels have identical semantics.
- platform check hoisted above the transcript scan.
The salvaged fix ran the injector against a copy.copy(agent) whose
tools/valid_tool_names pointed at the staged pair, wrapped in a blanket
try/except. A shallow copy of a live AIAgent (locks, DB handle, in-flight
attribute writes from the late-binding thread) is a workaround for the gate
mutating in place, and the except turned any failure into a silently
published snapshot WITHOUT message_agent.
Extract the gate as tools.bot_mode_dm.message_agent_authorized(agent) (the
same predicate ensure_message_agent_tool already used), and have the
snapshot builder append message_agent_tool_schema() to the staged list
directly when it passes. No copy, no swallow; same tests, same live
behaviour (compaction / between-turns / resume keep the tool; ordinary
sessions scrubbed).
For each issue anchor present in BASE 63279301bc non-test .py and absent on HEAD, the BASE comment/docstring block was re-attached at the HEAD location of the code it explained (matched by the distinctive code line / enclosing def). Sentences already covered by an existing HEAD comment were deduped; the issue number always survives. Insert-only: no code lines changed.
_stdio_children_dead_impl/_refresh_tools_task folded into their methods,
_recover_401/_is_invalid_client_at_token_endpoint defensive getattr chains
collapsed, lifecycle pid ledgers and drain loop tightened, WHY-preserving
docstring compaction across the group. Schemas byte-identical.
