         Use read_meetingnote to inspect frontmatter such as title, attendees, projects, start_time, and end_time.
         Use read_context and write_context as your own meeting notebook. Its frontmatter may include agenda from the calendar appointment. Record useful internal notes, missing context, requests for future tools, suggested improvements, and relevant context discovered from other sources. Keep user-facing summary content in the summary note.
         Use add_dictation_word when project context, user notes, or transcript evidence show that a domain term, acronym, name, or unusual word is likely to be repeatedly mistranscribed. Add only the canonical spelling, one term at a time.
+        Use add_attendee and remove_attendee to sharpen the meeting attendees list from clear transcript evidence and screenshot OCR participant evidence. Treat OCR that says visible people are a partial screenshot result as incomplete evidence; do not remove attendees solely because they are absent from a partial screenshot.
+        Use override_speaker only when you are very certain that a transcript speaker label belongs to a named person, for example from user notes, OCR evidence with a matching timestamp, or very clear context cues. Provide the exact speaker label from the transcript and the replacement speaker name. If the replacement speaker already exists in the transcript, use merge=true only when you are certain both speaker labels are the same identity; otherwise do not merge them.
+        Use delete_identity only when you are certain that an existing speaker identity was wrongfully matched. Provide the exact identity name currently used in the transcript.
         After writing the summary, update existing project files when the meeting produced durable project knowledge, decisions, next steps, or context.
         Use list_projects first to see which projects are bound to this meeting. Use search and read_projectfile before changing existing project files.
         The summary note should contain concise sections for summary, decisions, open questions, and next steps.

After transcription has fully finished, Meeting Assistant automatically runs the summary pipeline for the meeting. The summary agent can add and remove meeting-note attendees when transcript or OCR evidence is clear; partial participant evidence from screenshots should not be used to remove invitees by itself. It can also override a transcript speaker label with a named speaker only when the evidence is very certain, such as a user note, OCR at a correlating meeting timestamp, or a clear context cue. If that named speaker already exists in the transcript, `override_speaker` refuses by default; the agent must pass `merge=true` only when it is certain both labels are the same identity. When it is certain that a speaker identity was wrongfully matched, it can delete that identity, relabeling transcript speaker labels to `Removed-<n>` and removing the local speaker identity database row before future matching. Final speaker identity learning and candidate updates run after the summary pipeline finishes so they use the summary-refined attendee list and any recorded speaker identity changes. `ReconnectionAttempts` and `ReconnectionDelay` control retries for transient model endpoint failures such as LiteLLM token refresh or 5xx responses.

Meeting Assistant estimates the outgoing Responses payload size, logs the estimated token count and remaining context, and compacts the conversation when only the configured remaining ratio is left. It first attempts `POST /v1/{ResponsesCompactPath}` on the configured OpenAI-compatible endpoint. If that endpoint is unavailable or returns invalid data, it falls back to Microsoft Agent Framework compaction: collapse old tool results, summarize older message groups, preserve only the last four user turns if needed, and finally drop oldest groups until the request is back under budget.

+# Change: Refine attendees from screenshot OCR during summary
+
+## Why
+Calendar metadata often contains invited people rather than actual participants. Screenshots can reveal visible meeting participants, but OCR needs to state whether the visible people are complete or only partial evidence. The summary agent should be able to use that evidence to adjust the meeting attendee list before final speaker identity candidate updates run.
+
+## What Changes
+- The default screenshot OCR prompt asks the vision model to say whether visible people are the exact meeting participant set or only a partial result.
+- The summary agent has scoped tools to add and remove attendees from the current meeting note.
+- Summary instructions tell the agent to use transcript and OCR evidence to sharpen meeting attendees conservatively.
+- Final speaker identity learning/candidate creation runs after summary generation so it uses the summary-refined meeting attendees.
+
+## Impact
+- Affects screenshot OCR prompt defaults, summary-agent tool surface, summary instructions, recording finalization order, and speaker identity candidate timing.
+- Adds behavior tests for OCR instructions, summary attendee tools, and final speaker processing after summary.

+# Change: Switch transcription profile during an active meeting
+
+## Why
+Meetings can change spoken language or transcription requirements without being separate meetings. The user needs to switch from one launch profile to another during an active recording, for example from German to English, without creating new meeting artifacts or prematurely starting summarization.
+
+## What Changes
+- Profile hotkeys pressed during active recording switch the active meeting to that profile instead of stopping and summarizing the meeting.
+- Switching keeps the current meeting note, transcript, assistant context, summary path, and metadata.
+- Switching stops and drains the current speech recognition pipeline, buffers captured audio while the old pipeline drains, inserts a transcript marker, clears run-local speaker label mappings, and starts a new speech recognition pipeline using the requested profile options.
+- The final stop after one or more switches still summarizes once for the same meeting.
+
+## Impact
+- Affects recording coordinator lifecycle, launch-profile hotkey semantics, live transcription buffering, speaker mapping lifecycle, and transcript output.
+- Adds behavior tests for profile switching without metadata recollection or new artifacts.
