Display the active Todo task with the Gentle icon across at most two rows, without duplicating agent state. Keep metadata bounded and clear it at lifecycle boundaries. Closes #1704

Navigate logical layers of code changes, visualize relationships, and explore their blast radius. 📝 WalkthroughWalkthroughThe change adds an extension that publishes a sanitized, bounded summary of the active Todo title to Herdr for eligible root interactive Pi sessions. It adds geometry lookup, serialized metadata updates, lifecycle clearing, tests, and documentation. ChangesActive Todo summary

Merge Risk: 🔵 Low · up to An active task title may remain visible briefly after shutdown. Flush the queued clear promptly; the existing TTL provides a fallback. Security Architecture ReviewSecurity architecture risk: 🔵 Low · up to The new reporting path limits publication to eligible root interactive sessions, bounds and sanitizes task text, and avoids shell interpretation. The main residual risk is that shutdown may leave a task title visible until expiry. Downstream expiry and ownership enforcement have not been verified. Retained concerns

Review comments at @docs/readme-reference.md:
- Around line 101-102: Update the continuation-row description in the
documentation to state that the extension supplies a two-space prefix,
separately noting that Herdr may normalize leading whitespace when rendering.
Locate the text describing the first row and optional continuation; do not
attribute the prefix to the reporter.
Review comments at @lib/herdr-activity.ts:
- Line 61: Update the break-selection logic in activitySummary so it uses an
earlier space only when the remaining title still fits within the available
rows; otherwise retain the full first-row fit to avoid unnecessary truncation
and ellipsis.
- Around line 83-84: Update the row-fitting logic in the formatter around fit so
each token value is limited to 80 characters before choosing the single-row or
wrapped path, adding the formatter’s ellipsis when clipped; retain the existing
combined byte limit.
- Line 110: Update the executable passed to execFile in the summary-update flow
to use env.HERDR_BIN_PATH when present, falling back to "herdr" when it is
absent; leave the existing metadataArgs invocation unchanged.
- Line 74: Update the control-character filter in the Todo title sanitization to
remove U+061C alongside the existing bidi controls, and add a sanitization test
confirming a title containing U+061C omits it from the summary.
- Line 137: Update the deduplication guard in the method containing this
condition so it compares against last only when no send is running; retain
pending-value deduplication and the closed/force behavior. Add a regression test
for idle requesting a clear while a send is in flight with no pending value,
verifying the stale summary is cleared after the send completes.

All local automated checks ran sequentially with Herdr environment variables unset and a 1-GiB Node heap limit. No full-suite parallel run was used for final verification.

Review follow-up
Commit
76b46e33adds five focused regressions and fixes the validated review findings:HERDR_BIN_PATHwhen supplied, with theherdrexecutable onPATHas the fallback.The docs now explicitly describe the extension's two-space continuation prefix and Herdr's whitespace normalization. Latest RED/GREEN and independent verification evidence is recorded in the task document.
Review scope and limitations
This is one cohesive feature PR with 696 additions across seven files, including its tests and docs. The single-PR delivery was explicitly selected rather than splitting the projection from its integration and verification; no code was compressed or tests omitted to meet a line budget. No
size:exceptionlabel is requested.Herdr renders configured rows individually, so the optional continuation uses a separate token. Geometry uses a bounded persisted session snapshot with a five-second cache; saved width can lag resizing, and unsupported layouts use a conservative fallback. Leading continuation whitespace may be normalized by Herdr.
No managed Herdr bridge, lifecycle authority, personal configuration or package dependency is changed by this commit. Users opt into the two metadata rows through their Herdr configuration.
