memory: the operator ruled on all five — U7's departure approved, main pushed

"accept all recs, or make good ones." Four of five executed.

APPROVED: drop subfolder sections for filename-prefix groups. The U7 contract
moves to APPROVED and ROADMAP's U7 row and deterministic-order table are
rewritten -- groups order by the position of their first member in sorted(rel).

SETTLED: `unanswered` means has-an-open-pick, the reading that shipped. The
has-no-mark-at-all reading is a different question and is parked to v1.1 rather
than left pending.

PUSHED: main and both release tags reached origin -- the first time this repo's
U6 work has existed anywhere but this box. Recorded because --follow-tags
carried neither tag: both are LIGHTWEIGHT per the SemVer policy and that flag
only follows annotated ones, so a lightweight release tag needs its own push.

NOT SENT: the 17-handle note was blocked by the auto-mode classifier because a
multi-recipient send is gated on explicit operator approval. The blanket ruling
ratifies the note's content, not that specific approval, and the gate held
correctly. Drafted in full with its recipient list at
docs/pending/fleet-note-booth-link-refusal.md so it survives a context clear.
Not worked around.

NOT SEEDED: "no seeding yet" was a specific prior instruction rather than a
recommendation of this session's, so the blanket acceptance does not overwrite
it.

⚠ The approval leaves a trap: test_no_group_rail_is_shipped_yet exists to stop
an UNAPPROVED group rail, and the rail is now approved. It has inverted and
must be deleted by whoever builds the rail, or it blocks correct work while
reading like a real invariant. Named in the handoff's first step for that
reason.
