 - Owner reviewed the four demo captures locally and approved the set. Signoff recorded in `Docs/reviews/0.1.4-review.md` (7/7 items) and in the per-shot `Approved` column of `Screenshots/README.md`.
 - The three geometry items that `0.1.4` did not finish — retail neighbours from their own references, hero fluting/motto band, blockout cleaning — move to a new **`0.1.5` Façade finishing** patch rather than growing this one, plus a much-needed **1440p performance re-measure** (625 kit actors have never been measured; `0.1.0` measured 414 fps).
 - Decision recorded because it sets a precedent: finish and sign off a version when its _stated_ scope is done, and carry leftover scope into the next patch — do not let a patch accumulate unmeasured geometry.

-## 2026-11-09 — quality priority flipped: realism first, performance last
-
-- Owner decision: realism leads; performance closes the quality list. Applied in
-  `Docs/Architecture/01_introduction_and_goals.md`, `10_quality_requirements.md`,
-  `04_solution_strategy.md`, the combined `architecture.md`, `Docs/release-checks.md`
-  (performance section now last, with the reason), `ROADMAP.md` (a "Quality priority"
-  section) and `AGENTS.md` (the tie-break rule next to the scope-cutting rule).
-- Ordering used: 1 visual realism, 2 geographic fidelity, 3 walkability/usability,
-  4 build reproducibility/portability, 5 provenance, 6 performance.
-- **Both revisions carry the same guard so the order cannot be used as an excuse:**
-  performance is a *floor*, not a preference — 60 FPS at 1440p without frame
-  generation must be met at every release, and if realism cannot fit, the realism
-  scope is cut deliberately and recorded in `CHANGELOG.md`, never the frame rate.
-  Walkability outranks realism in one direction: a block the player falls through is
-  not a demo.
