Summary

  • Seeded inbound attachments can carry author text for Cosmo context, and chips with text open a read-only preview on click.
  • Cosmo panel is resizable via SplitPanel, with a thinking/busy indicator while streaming or running quick actions.
  • Scenario seeds support relative date tokens (${today}, ${next week}, etc.), and grading notes move to a rubric.json sidecar so scenarios/Cosmo never see the rubric.

Changes

Worth a close look:

  • Attachment text path: serializeAttachments feeds Cosmo; the reading pane only makes chips interactive when text is present. No file parsing.
  • Shell layout: rail stays fixed; mail + Cosmo sit in SplitPanel with split % in sessionStorage. Collapses cleanly when the assistant is disabled.
  • Relative dates: resolved once in loadScenario so new sessions get absolute timestamps; existing sessions keep whatever was already seeded.
  • Rubric sidecar: /api/config strips grading notes; extract report mode reads rubric.json / *.rubric.json (or --rubric).

Test plan

  • npm test
  • cp scenario-examples/02-reply-vendor-negotiation.scenario.json scenario.json && cp scenario-examples/02-reply-vendor-negotiation.rubric.json rubric.json && npm run dev
  • Drag the Cosmo divider; reload and confirm the split persists for the tab
  • Ask Cosmo something and confirm the thinking spinner; try a quick action too
  • Open Dana's quote attachment chip and confirm the read-only preview; name-only chips stay inert
  • Add a ${today} / ${3 days from today} token in a seed body or date, restart, confirm it expands
  • npm run report and confirm rubric notes appear; confirm /api/config has no rubricHints

…rubric sidecar

Make the mail/Cosmo shell resizable, show busy state while Cosmo works, preview
seeded attachment text on click, resolve relative date tokens at seed load, and
move grading notes out of scenario.json into a sidecar used only by extract.

📝 Walkthrough

Walkthrough

The change moves scenario grading notes into optional rubric sidecar files and adds report support for those files. Scenario loading now expands relative-date tokens in inbox data. The mail interface adds a resizable mail and assistant layout, text attachment previews, and assistant activity indicators. Documentation, example scenarios, and tests are updated for these changes.

Priority: ⬇️ Low

Merge Risk: 🟡 Moderate · up to 3fcb2

Fix the extractor's rubric handling before merging: an invalid sidecar should not block non-report modes, and a mistyped --rubric path should fail with an error. The assistant panel also has small busy-state gaps: Enter still sends during a quick action, and the controls are not refreshed when a quick action starts or ends.

🟡 Minor · Apply the quick-action busy guard to keyboard submission. · app.js:2506

public/app.js:2506
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Apply the quick-action busy guard to keyboard submission.

During a quick action, the assistant input remains enabled. Its Enter handler calls sendAssistant() directly. This guard checks only streaming chat, so Enter sends a chat request even when the new busy check disables Send.

Use assistantIsBusy() at this submission entrypoint.

Proposed fix
-  if (!chat || chat.status === 'streaming') return;
+  if (!chat || assistantIsBusy()) return;

Update the submission guard in sendAssistant to use assistantIsBusy() instead of
checking only for streaming status, so keyboard submissions are blocked during
quick actions as well. Preserve the existing guard for a missing chat.

Review comments at @extract-conversations.js:
- Line 162: Guard the rubric-loading block around existsSync(rubricPath) with
mode === 'report', so full, submission, thread, and assistant modes skip rubric
access while report mode retains the existing loading behavior.
- Line 162: Update the rubric existence check around rubricPath to exit with a
clear error when explicitRubricFile is set and the requested file is missing.
Keep missing inferred sidecars optional and preserve the existing handling for
available rubric files.

Review comments at @public/app.css:
- Line 1170: Move the reduced-motion override after the typing-dot rules so its
animation and opacity declarations take precedence when prefers-reduced-motion:
reduce matches; preserve the existing override values.

Review comments at @public/app.js:
- Line 1994: At both quick-action transitions that call
updateAssistantThinking(), also refresh the clear control with
updateAssistantClearBtn() and recompute Send availability from the input, chat
state, and assistantIsBusy(); preserve any existing input-disabled state.

Review comments at @public/index.html:
- Line 148: Update the assistantThinking indicator to expose its “Thinking…” and
“Working…” text through a polite status live region, and ensure it is outside
any aria-busy ancestor or that aria-busy is limited to the message region.

Tighten report-only rubric loading, sync clear/Send on quick-action busy,
announce thinking via a status live region, and move reduced-motion overrides
after typing-dot rules. Note the sendAssistant busy-guard follow-up.
