Trim the salvaged detector/delivery pair to the salvage bar and fix the delivery half. The PR resolved the refresh selection as platform_toolsets.<surface> (desktop/tui), a key no config path writes, so _get_platform_tools fell back to the constructed hermes-<surface> composite that resolves to 0 tools (a cold resume went 30 -> 1 tool). Delivery now goes through the builder new desktop/TUI sessions use (tui_gateway.server._load_enabled_toolsets(platform) + _load_disabled_toolsets) as an explicit refresh_agent_mcp_tools override, so the refreshed set equals a fresh session's on that surface; only desktop/tui agents are long-lived, every other surface builds a fresh agent per process/turn and is left alone. Drops the toolsets.py/tui_gateway policy relocation and the raw-value fallback in the fingerprint; keeps the detector (platform_toolsets + agent.disabled_toolsets replace the dead tools.enabled_toolsets key) and the tools re-pin after the refresh. Tests: 2 invariants in tests/agent/test_bot_chat_toolset_refresh.py (desktop -> builder consulted, disabled override passed, re-pinned; cli -> untouched) and the existing fingerprint axis test now edits the key `hermes tools enable/disable` writes.

"""Bot Mode roster probe — canonical Bot Chat system prompt section.
|
|
|
|
When any profile carries ``ui_meta['hermes-bots']`` in profile.yaml (Bot-Mode-managed),
|
|
a bot's canonical "Bot Chat" session — ONLY that session (agent/system_prompt.py enforces
|
|
the ``BOT_CHAT_TITLE`` gate) — gets a "Messaging other agents" section. Silent (``""``)
|
|
when no profile is managed or on any error. Older desktop builds appended a frozen copy of
|
|
the section to SOUL.md; ``strip_legacy_protocol`` drops it at load time so the live roster
|
|
here is the only copy any session sees. Cached per (process, home) so compression rebuilds
|
|
produce identical bytes. Toggle: ``agent.bot_mode_protocol``. Also hosts path/roster
|
|
helpers shared by ``bot_mode_dm`` and ``bot_relay``.
