Fix all 6 confirmed findings from today's gap audit

Implements every confirmed finding from the workflow-based audit of
CURABIS Standard's agent model (7 finders + adversarial verification,
8 confirmed / 5 refuted):

1. Roemer/Florence phantom wiring - roemer.agent.md claimed Florence's
   heartbeat "may summon me when a ward smells of drift" with nothing in
   florence.agent.md or HEARTBEAT.md implementing it. Fixed by adding an
   explicit "Kald Roemer" instruction to HEARTBEAT.md ward 6 (agent
   visibility, his actual domain), mirroring ward 8's existing "Kald
   Weber" pattern, and correcting roemer.agent.md's own claim to match.

2. m365.agent.md's "Florence's morning brief pattern" was a one-way
   orphaned reference - a full 4-step pattern with nothing in
   florence.agent.md implementing it. Added it to florence.agent.md as
   an explicit on-demand capability, separate from the timestamp-gated
   Round protocol.

3. An Ergasterion "PROCEED WITH CHANGES" ruling had no way to be checked
   against the eventual diff - al-review's checklists never referenced
   it. Added ERGASTERION_RULING to the [CURABIS-STATE] vocabulary,
   wired Ergasterion to write it, and added a BLOCKing checklist item to
   al-review's Titus checklist that verifies required changes were
   actually implemented.

4. curabis-task-state-check.yml was headered "Deterministic enforcement
   (not LLM diligence)" but only checks checkbox order, only blocks
   anything if a human separately enabled branch protection (never
   verified anywhere), and doesn't exist at all for the PTE track.
   Corrected the header's claims and added Roemer station 14 to verify
   branch protection is actually configured.

5. Mode C's only safeguard against a support user reaching
   Curabis/QualityHub was a single manual eyeball check with no re-check
   ever. Strengthened Step 2 to cover team-inherited and org-default
   access paths, added an append-only support-user registry, and added
   Roemer station 15 to periodically re-verify every registered user
   against it.

6. Columbo's persona was presented as genuine autobiography with no
   disclosure of its fictional TV origin (Levinson & Link, Peter Falk),
   unlike Smiley which discloses explicitly. Added a reader-facing
   editorial note - never something Columbo says aloud, since unlike
   Smiley he actually performs the persona to customers.

+## On-demand — Morning brief (2026-08-03)

+This is separate from the scheduled Round protocol above — it does not go
+through the Step 0 timestamp gate, and it is not one of HEARTBEAT.md's
+wards. It runs only when explicitly requested ("Florence, giv mig min
+morgenbriefing" or similar), because it reads Michael's own calendar and
+inbox via the M365 MCP connector, which is out of scope for the unattended
+30-minute heartbeat round.

+Follow `m365.agent.md`'s "Florence's morning brief pattern" exactly, in
+order:
+
+1. **Calendar** — today's events (`outlook_calendar_search`)
+2. **Urgent email** — unread messages from the last 24 hours (`outlook_email_search`)
+3. **BC tasks** — via BC MCP, not M365 (see `bc-mcp.agent.md`)
+4. **Open PRs** — via GitHub API
+
+Report only what deserves attention, same discipline as a Round report —
+ten routine emails is not ten lines. This section exists because
+`m365.agent.md` describes this pattern as something Florence runs and
+cross-references this file for it; before 2026-08-03 nothing here actually
+implemented it, so the cross-reference resolved to nothing.
