Lane F R5 start: archive R3/R4 instruction claims + v2 flags table + v1.1 watch

- ROUND3/ROUND4_INSTRUCTIONS.md: 'SUPERSEDED by R5' banner (F4 archive task).
- LANE_F_NOTES §10: round-5 tracking — v2 flag-seam table (?plansrc/?winmap/?dig/?roster,
  all pending owning-lane specs), v2 QA-harness plan, v1.1 watch.
- F-progress: round-5 section. Confirmed fal already un-parked at 039c179 (no F change needed).
- v1.1 tag is on watch for Lane C re-map (C1) + Lane E hero-prop bake (E1).

+## Round 5 (v1.1 close-out + v2 foundations) — IN PROGRESS
+
+Lane F role: **v1.1 watch** + v2 flag-seam wiring + QA-harness-for-v2 + shared-tree marshal.
+Full tracking in [`LANE_F_NOTES §10`](docs/LANES/LANE_F_NOTES.md).
+
+| task | status |
+|---|---|
+| **fal un-park check** | ✅ Verified already done — `039c179` un-parked fal in Lane E's brief (decision #4 + Lane E task 3: glass-case + bus-shelter + optional magazine-rack, ≤2 attempts, costs logged in AUDIT.md). **Nothing for F to change.** |
+| **archive R3/R4 instruction claims** (F4) | ✅ Added "SUPERSEDED by R5" banner to `ROUND3_INSTRUCTIONS.md` + `ROUND4_INSTRUCTIONS.md`. |
+| **v2 flags table** (F4) | ✅ Scaffolded in LANE_F_NOTES §10 (`?plansrc=osm` A, `?winmap=1` B, `?dig=1` C, `?roster=stream` D) — all pending owning-lane specs. |
+| **F1 tag v1.1** | ⏳ **WATCH** — blocked on C1 (re-map `counter_till`/`record_crate`) + E1 (hero-prop bake ≤8k). No round-5 lane commits yet (HEAD `039c179`). |
+| **F2 wire v2 seams** | ⏳ pending lanes documenting call-sites (esp. C's `?dig=1` interior-mode input seam — real work, F owns the mode machine). |
+| **F3 v2 QA harness** | ⏳ determinism gate (first-interior-hash per seed) · flags-off regression check (v2-prime-law enforcement) · v2 smoke → qa.sh warn-gate. Build as flags land. |
+
+Base state: v1.0 (`2698b40`), `qa.sh --strict` GREEN 4/4, tree clean.

+## 10. Round 5 — v1.1 close-out + v2 flag seams (Lane F tracking)
+
+Round 5 (v1.1 polish + v2 foundations behind flags). **v2 prime law:** default boot stays
+v1-identical; `GOLDEN.hash 0x3fa36874` must not move; `qa.sh --strict` green at every commit.
+
+### v1.1 tag — ⏳ WATCH (blocked on C1 + E1)
+Tag `v1.1` once **Lane C** re-maps `counter_till` + `record_crate` (C1) and **Lane E** bakes the
+hero props ≤8k (E1). F then: verify record/milkbar/opshop interiors (GLB counter+till correct, bins
+upgraded, baked props look right), re-capture ONLY the 2 interior tour shots if improved, qa green →
+`git tag v1.1` (local). *Nothing to tag yet — HEAD `039c179`, no round-5 lane commits.*
+
+### v2 flag seams — table (F wires `web/index.html` + `tools/` as lanes document them)
+Every flag **default-off + independent**. Wire only from the owning lane's NOTES call-site spec.
+
+| flag | owner | what | F wiring | state |
+|---|---|---|---|---|
+| `?plansrc=osm` | A | second plan source (OSM fixture) behind the CityPlan contract | select in shell plan bootstrap | ⏳ pending A |
+| `?winmap=1` | B | parallax interior-mapping window shader | none (B owns glass); F adds the flag pass-through if needed | ⏳ pending B |
+| `?dig=1` | C | dig.js crate-riffle on procedural stock | **real work — interior-mode input seam** (`interiorMode.onInteract(fitting)`); F owns the mode state machine | ⏳ pending C spec |
+| `?roster=stream` | D | chunk-streamed citizen roster | wire the flag + confirm B's `ctx.onChunkBuilt/onChunkDisposed` feed | ⏳ pending D |
+
+### v2 QA harness extensions (F3) — build as flags land
+- **Determinism gate:** pin `plan-hash` + `first-interior-hash` per `(seed, plansrc)`. Synthetic
+  stays `0x3fa36874`; add the osm-fixture hash when A lands.
+- **Flags-off regression check:** boot no-flags → assert plan hash + a settled draws/tris snapshot
+  within tolerance of the v1 baseline (catches a v2 flag leaking into the default path). *This is the
+  enforcement arm of the v2 prime law — build early, before flags land.*
+- **v2 smoke:** boot each flag on, walk 2 chunks, enter 1 interior (+1 dig if C landed), 0 console
+  errors. Wire into `qa.sh` as a **non-strict (warn) gate** this round; strict next round.
+
+### Marshal
+Shared-tree arbiter this round: F owns `web/index.html` + `tools/`; if two lanes collide on a file,
+F arbitrates. Cross-lane asks → the owning lane's NOTES, not silent edits.
