 | S4-c2 owner repair | **STOPPED UNLANDED 2026-09-04** — owner-authorized implementation `a094bf2b7` is clean in `s4-c2-impl`; packet §15 is the review record | G3/G4 UNPASSED | The repaired renderer behavior passed the retail lens: exact whole-leaf pass membership, `0x08`/`0x09` CLIP, row-3 override, blend/reference/depth state, sentinel separation, detail state, rollback, allocation, AP-238/AP-240. The lens still returned FAIL: commit body omitted the required per-mutation first failures, packet mutation 5 names the wrong first assertion/address, and four source/test comments are stale. Sequential production lens therefore did not run. Correcting those items is a post-review fourth repair, which §14 does not authorize. Nothing landed or graphically gated; resume only by explicit owner process decision. |
 | S4-c2 attempts 1–5 | **ATTEMPT 1/5 CONSUMED; ATTEMPT 2/5 PASSED AND LANDED 2026-09-04** — reviewed implementation `daaeab0ba`; campaign stack `89f1e2676` → `9ccb61a8e` → `0aa166aa0` → `252886e84`; packet §17 | G3/G4 UNPASSED | Sequential retail/evidence then production/gate-honesty PASS.

Official no-retry hermetic 16,734/1: sole unchanged global `Console.Out` capture race, exact theory 2/2 isolated. InstalledDat 255/10 documented/1. Validation routes `selfgate-20260904-115818-s4c2-landed-route` and `selfgate-20260904-120025-s4c2-landed-g3b` PASS provisional.

The earlier stop remains in history at `06b986622`. | G3/G4 UNPASSED | Final retail lens PASS; production behavior/lifecycle/allocation/scope clean. The narrow independent gate-honesty re-review PASS reproduced the exact first failure (AP-table-boundary `Assert.True`, `rowIndex=-1`, before `Assert.Single`), restored AP-241 byte-identically, and passed the pin 1/1. Fresh campaign: Release 0W/0E; focused class lane 96/96; no-surface 1/1; AP pin 1/1; real allocation 2/2 at 0 B; shader 32/32; `git diff --check` clean. No client launched. NEXT: write c3b's deletion-only contract from the landed code; G3 stays locked until c3b lands. |
-| S4-c3b | **CONTRACT WRITTEN — packet §22; implementation pending.** Delete only the superseded classic-group `LocalSortCenters`/`CachedBatch.LocalSortCenter` sidecar and the dead alpha camera-parameter/digest chain. Preserve c3a's live per-cell/particle CYpt keys, opaque `SortDistance`, building/private/portal distances, two FIFO lists, all state/barriers, and AP/AD rows. Correct/pin the three `AlphaFlushCounts_*` reasons; verify the old bias/stencil/distance-sort paths stay absent. | G3/G4 UNPASSED | One Sonnet implementation, then sequential retail/deletion and production/gate-honesty lenses. Dual PASS lands the deletion-only chunk and unlocks G3. No client before landing. |
+| S4-c3b | **LANDED 2026-09-04** — implementation `26e97ba41`, provenance contract `5110bf676`, packet-only correction `3f2f00c9f`; packet §22–§24. Dead classic-group `LocalSortCenters`/`CachedBatch.LocalSortCenter` storage and the alpha camera-parameter/digest chain are deleted. Live per-cell/particle CYpt keys, opaque `SortDistance`, building/private/portal distances, two FIFO lists, all state/barriers, and AP/AD rows remain. | G3/G4 UNPASSED | Retail/deletion lens PASS. Production lens found no code defect and one artifact-provenance omission; packet-only fix round 1 passed its narrow re-review. Fresh campaign: Release 0W/0E; App 132/132; Core 29/29; real allocation 2/2 at 0 B; shader 32/32. No client launched. G3 unlocked; run its three graphical routes next. |

+S4-c3b is LANDED. Reviewed scratch implementation `4eca2a4f` maps to campaign
+commit `26e97ba41`; provenance contract `8074a6b4d` and packet-only correction
+`92f9b4bbb` map to `5110bf676` and `3f2f00c9f`.
+
+The retail/deletion lens returned PASS with no finding after checking the named
+decomp and paired executable/PDB: `AddMeshToAlphaList @0x0059C230` has no
+camera/distance input, `FlushAlphaList @0x0059D2E0` replays CLIP then ALPHA in
+FIFO index order, and `CShadowPart::insertion_sort @0x006B5130..0x006B519D`
+is strict-descending and stable for equal keys. The removed grouped centers fed
+only dead storage and a diagnostic hash. Walk CYpt, particle authored-center
+distance, opaque `SortDistance`, building/private/portal distances, queue and
+router behavior, barriers, and generic stencil state remain live and unchanged.
+
+The production/gate-honesty lens found no code, test, allocation, lifecycle,
+scope, mutation, or gate defect. Its sole MAJOR was §22.7's omission of the
+pre-commit artifact identity. Fix round 1 changed only this packet. Both
+artifact summaries name parent `a0523e605` and `WorktreeDirty=true`; both
+30-entry SHA manifests verify; the transcript blob is
+`c755c1379feeba5fe5382fa0b0db243e7169b4e9` at base, implementation tip,
+contract, fix, and current worktree; and the hermetic TRX records the exact
+source-truth pin PASS. The narrow re-review returned PASS and closed the finding.
+
+Fresh campaign verification at `3f2f00c9f`: Release solution build PASS with
+0 warnings / 0 errors; focused App 132/132; focused Core 29/29; real warmed
+allocation pins 2/2 at 0 B; shader/manifest/SPIR-V 32/32. The campaign worktree
+was clean after integration. No client was launched for c3b. G3 is now unlocked;
+G4 remains unpassed and nothing may merge to main.
