Problem

/model <name> switch is silently lost when it's the first message after a session auto-reset. The session DB shows the new model, the UI says the new model, but actual API calls use the previous/default model.

Root Cause

/model commands are handled by _handle_model_command() which returns directly without entering _handle_message_with_agent(), where was_auto_reset is normally consumed. The next regular message finds was_auto_reset still True and the cleanup at line 8378 wipes _session_model_overrides, silently losing the model override set by /model.

Fix

Two-part fix:

  1. _handle_message_with_agent() (run.py): Capture was_auto_reset into a local variable and consume the flag immediately after the cleanup block so subsequent messages in the same auto-reset session don't re-fire the cleanup.

  2. _handle_model_command() (slash_commands.py): Consume was_auto_reset on the session entry obtained from get_or_create_session() so that even when the command bypasses _handle_message_with_agent(), the flag is cleared before the next regular message arrives.

Verification

  • was_auto_reset consumed immediately after cleanup prevents re-fire
  • _is_new_session and context notice still work (use saved local variable)
  • /model X as first message after auto-reset now works correctly

Closes #48031

…ipe after auto-reset

When /model <name> is the first message after a session auto-reset,
the command handler (_handle_model_command) returns directly without
entering _handle_message_with_agent(), so was_auto_reset is never
consumed. The next regular message finds the flag still True and the
cleanup at line 8378 wipes _session_model_overrides, silently losing
the model switch.

Two-part fix:
1. In _handle_message_with_agent(), capture was_auto_reset into a local
   variable and consume the flag immediately after the cleanup block,
   so subsequent messages in the same auto-reset session do not re-fire
   the cleanup.
2. In _handle_model_command(), consume was_auto_reset on the session
   entry obtained from get_or_create_session(), so that even when the
   command bypasses _handle_message_with_agent(), the flag is cleared
   before the next regular message arrives.

Closes NousResearch#48031

…reset

When `/model X` is the FIRST message after an idle/daily/suspended auto-reset,
the slash-command path stores a session model override but leaves
`session_entry.was_auto_reset = True` (it never passes through
`_handle_message_with_agent`, which is where the flag was consumed). On the
NEXT regular message, the auto-reset cleanup block pops the freshly-stored
model/reasoning override BEFORE the flag is consumed — so the switch is
silently lost and resolution falls back to the config default, while the
session DB still shows the switched model (a two-sources-of-truth divergence).

Consume the flag at both sites:
  1. gateway/run.py — capture `was_auto_reset` into a local and set the
     attribute False immediately at the top of the cleanup block, so the
     cleanup can't re-fire on a later message and wipe an override stored
     between turns. Downstream reads use the captured local.
  2. gateway/slash_commands.py — the model path consumes the flag before
     storing the override, so a /model-first-after-auto-reset isn't wiped by
     the next message's cleanup.

Thanks for the fix — same root cause (the was_auto_reset flag not being consumed before the first slash command after a session auto-reset, so the /model switch was silently lost). This shipped via #51025 (merged), which consumes the flag early so /model survives the auto-reset. Closing in favor of #51025. Fixes #48031.
