+## 12. Owner-authorized documentation/evidence exception — 2026-09-04
+
+The final production/gate-honesty lens found no production-code or test defect
+but returned FAIL after fix round 2 on two correction-worthy truth gaps:
+
+1. architecture and AD-21 say null-root publishes no cell-visibility answer,
+   while production completes `hasCompletedView=true` with an empty landscape
+   set; and
+2. the official lane summaries identify dirty bases, but the packet does not
+   independently bind those dirty source deltas to implementation commit
+   `9aadc917a`.
+
+Per the campaign rule, S5-c1 stopped and the campaign branch recorded that stop
+at `efb075619`. The owner then explicitly authorized a
+**documentation/evidence-only exception**: "correct docs and continue." The
+stop and both failed-lens results remain in history.
+
+The exception is bounded to:
+
+- truth-correcting the null-root sentence in
+  `docs/architecture/acdream-architecture.md`;
+- truth-correcting AD-21 in
+  `docs/architecture/retail-divergence-register.md`;
+- recording this exception and its evidence in this packet; and
+- updating only the S5-c1/S5 ledger rows in
+  `docs/plans/2026-09-01-campaign-overhaul-world-solidity.md`.
+
+No production code, tests, other register row, architecture section, or prior
+artifact may change. The correction must state that every non-login world frame
+participates, a walk contributes its exact landscape set, and null-root
+completes an empty set without reconstruction; login/portal remain false.
+
+After the documentation correction is committed, create fresh official
+evidence from that clean exact commit (not a dirty pre-commit tree):
+
+- `artifacts/s5-c1-exception-hermetic-20260904` — hermetic lane;
+- `artifacts/s5-c1-exception-installed-20260904` — InstalledDat lane.
+
+Both summaries must record the correction commit and `WorktreeDirty=false`;
+their manifests must verify completely. The older dirty-base artifacts remain
+preserved as historical evidence but are superseded for landing provenance.
+One narrow independent production/gate-honesty re-review verifies only the
+authorized documentation diff, exact clean artifact identity/counts/hashes,
+and absence of code/test changes. PASS permits landing and the graphical gate;
+any behavioral change or further correction-worthy finding stops again.
