+- `work-on-task-assistant`: the Phase 4 daily-note report may no longer claim `Already tracked` without a matching line in hand, and must quote the matched line verbatim. The phase searched the note correctly but nothing bound the report to the search result, so it could assert a task was tracked in the Must section when the note contained no reference to it at all — indistinguishable from a real match, and leaving the task absent from the day's record until a later `sync-progress` caught it. Observed 2026-08-22, where the gap went unnoticed for roughly three hours

 ## v0.114.4
 - `task complete`: the parent-goal roll-up now accepts an in-progress checkbox (`- [/]`), not just `- [ ]`. It matched only the pending marker, so a goal entry that existed and correctly named the task was skipped whenever the task was marked in-progress — and that is precisely the state a task being completed is usually in. The result was a `checkbox not found for task ... in goal ...` warning, task completion succeeding anyway, and the goal silently left stale. Both markers now roll up to `- [x]`

+  - This search is the ONLY basis for the "already tracked" report. Never report `Already tracked` without a matching line in hand — quote it verbatim (`ℹ️ Already tracked: <matched line>`). A tracking claim that names a section but no line is unverified, and reads identically to a real match while the task is in fact absent from the day's record. Observed 2026-08-22: the agent reported `Already tracked ([/] [[Review MoneyMoney - 2026W34-sat]] in Must section)` for a task that appeared nowhere in the note; it went untracked for three hours until `/vault-cli:sync-progress` caught it.
 - Add `- [/] [[{task_name}]]` or `- [/] {jira_id} {summary}` to Must section if absent
 - If found with `[ ]` → upgrade to `[/]`; if `[/]` or `[x]` → skip
