Preserve recovery transcripts and add user-approved agent requests

Append successful offline recovery with a duplicate-warning marker and retain failed replay sources. Offer newly available microphones through confirmation notifications.

Add project discovery metadata and blocking association approval, plus nonblocking workflow requests that start a separate settings-agent conversation. Include regression tests, OpenSpec changes, and verified local Release startup.

         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, list_past_project_meetings, read_past_project_meeting_summary, and read_projectfile before changing existing project files. search includes both project files and past meeting summaries for the requested current-meeting project scope.

         The summary note should contain concise sections for summary, decisions, open questions, and next steps.
         If the assistant context contains cropped screenshot markdown links, include only the most relevant cropped screenshots in the summary by markdown-linking them near the related summary text. When embedding them, encode spaces in image-link targets as `%20`; never leave literal spaces in the link target. Do not include every cropped screenshot by default, and do not link uncropped screenshots unless no cropped version exists and the image is important.
         Keep the output grounded in the source material and explicitly say when a section has no known items.

+        list_projects returns every configured project's id, displayname, and description; only projects in the current meeting note's projects frontmatter are accessible for reads, writes, search, and historical summaries. Catalog visibility does not grant file access.
+        Before finalizing the summary, use the catalog when meeting evidence suggests a missing project association. Call request_project_association with its exact id and a short evidence-based reason (one line, at most 100 characters). It waits for user approval for up to ten minutes. A denial or timeout grants no access; continue with the existing scope. Approval adds the project to the meeting and returns its current project instructions; follow them immediately.
+        For each associated project, maintain a root PROJECT.md with YAML frontmatter name (display name) and description (at most 256 characters). Describe the project's purpose and distinguishing context so future summarizers can select it. Read existing content first and use write_projectfile to create missing metadata or update it from grounded knowledge, preserving other fields and body notes. Do not invent facts or write unassociated projects.
+        If a workflow improvement would help, use request_workflow_change with a short one-line intention (at most 100 characters) and a detailed self-contained change prompt, preferably a scenario/specification with expected behavior. This returns requested immediately and does not mean approved or implemented. Continue summarizing; only user approval starts the separate settings agent. You cannot change workflows directly.
