docs: close the operator stack -- handoff rewritten in plain language

Jahni built the last two commits and the game looks fine. Closing the thread.

OPSTACK-HANDOFF.md fully rewritten. The old one had become a private dialect --
"you've started using very unique terminology, i have NO idea what you've been
doing" -- which is a failure of the document, not the reader. The new version
leads with what the op stack was for, says plainly that Phase 3 was never built
and is not being built, carries the honest three-week ledger (120 commits, every
feat: a port, the world unchanged by design), and translates the jargon.

Final state: 8/8 archetypes live and bit-identical, 14/14 tests green through
871ca19, violations 0, and 39% of tiles skipped in the running game against 0%
that morning.

Flagged in the handoff: 4d33321 and 91585ea are built but not re-verified -- the
suite has not been re-run since. Two named checks, and revert 4d33321 if either
fails; the 39% does not depend on it.

Direction agreed: no Phase 3, no further refactoring, old switch stays as the
oracle, next work is visible content from fable-idea.md.

+## 2026-08-16 (w) — CLOSED. The operator stack is declared done; direction changes to visible work.

+Jahni built `4d33321` + `91585ea` and reports the game looks fine. He asked for the handoff to be
+updated and the thread closed.

+### Final state
+
+- 8/8 archetypes live and bit-identical (115 000-sample field digest unchanged, eight equivalences).
+- 14/14 tests green through `871ca19`, `violations` 0 everywhere.
+- **39 % of tiles skipped in the running game**, from 0 % that morning.
+
+⚠️ **`4d33321` (boundary fold) and `91585ea` (warning demotion) are built but NOT re-verified** — the
+suite has not been re-run and the counters not re-read since. Recorded in the handoff with the exact
+two checks and the instruction to `git revert 4d33321` if either fails; the 39 % does not depend on
+it.
+
+### Direction, agreed
+
+**No Phase 3. No further refactoring.** The old `switch` stays as the oracle. Next work is whatever
+Jahni can see — `fable-idea.md`, F7 set-pieces, F9 audio. The handoff closes on the question that
+should have been asked in July: *what do you want the world to do that it doesn't?*
+
+This log stays append-only and stays the record of what was actually built. It ends here for the
+operator stack.
