+## Post-correction update (audit bounded correction pass, 2026-07-28)
+
+The independent audit refuted the bare claim "no dominant strategy." Two corrections + one disclosure:
+
+- **H2 fixed (menu incoherence exploit).** A discovered `Value Chassis + Premium Anchor` hybrid used to
+  dominate all three markets. A **menu-positioning coherence** lever (master plan §10.6) now makes a dish
+  priced far above the menu's own median tier less likely to be ordered, scaled by segment — **exactly zero
+  below a 2.0x-median threshold** so the three golden fixtures are byte-identical. After the fix the hybrid
+  **loses lunch and social** and is viable only in the enthusiast market (regression-locked in
+  `DominanceRegressionTests`). The distribution of the 9 named strategies is unchanged (still 2/3 distinct
+  winners).
+- **Dominance is now SEARCHED, not asserted.** The harness runs a bounded random search over the decision
+  space (`reports/balance/dominance-search.md`), so the claim is tested against the space, not 9 points.
+- **NEW-1 disclosed (not hidden).** The search still finds **one** residual dominator: a *uniformly
+  overpriced coherent* menu (e.g. Chicken@$52, Scallops@$41). Its prices are near its own median, so the
+  coherence lever correctly does not touch it. It dominates because M0 has **no repeat-visit / reputation
+  feedback**, so price and quality expectations have no economic teeth within a single service (the same
+  boundary as DECISION-LOG D-012). Strengthening price elasticity would change the Focused Value golden
+  (its burger is already slightly over the value budget), so it is **deferred to M0.5**, not hacked here.
+
+**Honest scoped claim:** *No single NAMED strategy wins every market (2/3 distinct winners), the menu-
+incoherence exploit is fixed, and one price-elasticity exploit remains — a manifestation of the disclosed
+no-repeat-visit M0 boundary, deferred to M0.5.* This is a fair basis for the M0 gate; it is not the
+unqualified "dominance ruled out."

+# M0 Bounded Correction Pass — Builder's Report
+
+Scope: correct the independent audit's 3 High + 5 Medium findings only. No M1, no new features, no content
+expansion. The PR-#1 branch was not modified; corrections live on `fix/m0-audit-corrections`.
+
+## A. Reviewed baseline
+- **Reviewed commit (PR #1):** `beb9289`.
+- **Correction branch:** `fix/m0-audit-corrections` (branched from `beb9289`).
+- **Final correction commit:** the tip of this branch (see the PR the branch is pushed to).
+
+## B. Sub-agent usage
+- **Phase B — 4 read-only investigators** (attribution, forecast, dominance, numerics/tests/docs), each on
+  an isolated copy of the clean clone; none modified the repo or branch. They reproduced every defect with
+  real numbers and proposed minimal fixes + tests. The lead (this Builder) independently verified each root
+  cause against the code, reconciled the reports, and implemented all code changes personally on the shared
+  files (`Simulator.cs`, `Result.cs`, `Tuning.cs`, `Forecast.cs`, `TextReport.cs`) to avoid concurrent
+  conflicts. Pre-fix reproductions are preserved in `PRE-FIX-AUDIT-EVIDENCE.md`.
+
+## C. Finding resolution
+| Finding | Disposition | Root cause | Correction | Tests |
+|---|---|---|---|---|
+| **H1** autopsy misattribution | **Refined & fixed** | incommensurable pressure scores (util proxy vs lost-party count) compared by max; 88% gate caused a flip | two-tier attribution by measured lost **contribution** per channel; busiest station is a secondary warning only | `AttributionTests` (5) |
+| **H2** dominant hybrid | **Fixed** | menu incoherence had no cost; a premium anchor on a value chassis captured margin free | menu-positioning **coherence** lever (zero below 2.0x median → goldens unchanged) | `DominanceRegressionTests` (2) |
+| **H3** biased forecast | **Fixed** | ceiling ignored peaking, walkouts, comps; operating leverage amplified it | realization factor + comp haircut + honest downward-skewed band; relabeled | `ForecastCalibrationTests` (3) |
+| **M4** CLI double price parse | **Fixed** | `(long)(double.Parse*100)` truncation | `Money.TryParse` integer-only | `MoneyParseTests` (16 cases) |
+| **M5** no FIFO/labor test | **Fixed** | caught only by golden checksum | direct FIFO dequeue-order test + labor-value test | 2 tests |
+| **M6** no-float guard bypass | **Fixed** | scanned only instance fields | widened to static fields + properties | guard test |
+| **M7** cross-OS overclaim | **Fixed** | contract/ADR asserted cross-OS as fact | reworded to "verified same-environment only" | n/a (docs) |
+| **NEW-1** uniform-overprice dominator | **Disclosed, deferred** | M0 has no repeat-visit teeth on price/quality | NOT hacked (would change a golden); recommended for M0.5 | dominance search reports it |
+
+## D. Causal-attribution evidence
+Pre-fix: all-grill/1-cook/lunch/seed 12345 flipped Seating→Kitchen at seats 19→20 purely on util crossing
+88% (lostCap unchanged at 42→43). Post-fix: seats 19 AND 20 both attribute to **seating**; the transition to
+**kitchen** now tracks the true binding constraint — verified by covers-served response: with one grill cook,
+covers-served *falls* 40→19 as seats rise past 20 (adding seats hurts → kitchen-bound → "kitchen"); with two
+cooks (kitchen headroom) covers *rise* with seats → "seating". The two-tier report reads: *"Primary loss:
+seating turned away N parties (~$X lost). Secondary: the Grill ran at 69% — high utilization, but not the
+largest loss."* (`AttributionTests`, `PRE-FIX-AUDIT-EVIDENCE.md`).

+## E. Forecast evidence
+Pre-fix contribution bias 2–15x high; band coverage 0/8 in 24 of 27 cells. Post-fix
+(`reports/balance/forecast-calibration.md`, 200 seeds): aggregate band coverage **61%** ≥ stated **55%**
+(per-market 55% / 54% / 74%). Focused Value/lunch expected covers now 70 (was 135) vs ~98 actual. The
+forecast now distinguishes **demand opportunity** (ceiling), **expected completed covers**, and a **wide,
+downward-skewed low-confidence contribution range**; confidence is stated at the measured floor, not
+aspirationally. Note: the per-cell "median covers bias" metric is inflated by degenerate strategies (a few
+covers → large %); the band coverage is the honest headline.
+
+## F. Strategy-space evidence
+`reports/balance/dominance-search.md` (500 random configs × 40 seeds). The `Value Chassis + Premium Anchor`
+hybrid: pre-fix dominated social (+$1518) and enthusiast (+$2208); post-fix it **loses lunch and social**,
+viable only in enthusiast. The 9 named strategies' distribution is unchanged: **2/3 distinct winners**, no
+single named dominator. **One residual dominator remains** (uniform-overprice coherent menu, min edge ~$340)
+— disclosed as NEW-1, rooted in the no-repeat-visit boundary, deferred to M0.5. The honest claim is now "no
+single NAMED strategy wins every market," not "dominance ruled out."
+
+## G. Technical verification
+- **Tests:** 103 passed, 0 failed (Core 54, Determinism 31, Scenario 18).
+- **Determinism:** golden checksums BYTE-IDENTICAL to pre-fix (`F07AA46F729A0A8F`, `24EE4A83E7436797`,
+  `7C4703D4A5375AF5`); same-seed reproduction and Debug/Release still match. All sim-changing corrections
+  (H1 attribution, H3 forecast) touch only checksum-excluded or pre-service state, so no golden was
+  re-baselined. The H2 coherence lever is exactly zero for the golden menus by construction.
+- **Accounting:** reconciliation invariants unchanged and passing.
+- **No float in Core:** widened guard passes; the last authoritative-path float (CLI price) removed.
+- **Cross-OS:** still single-environment (macOS/arm64); unverified and now documented as such.
+
+## H. Scope audit
+Clean. No M0 non-goal was built. The corrections are confined to attribution, forecast, choice-weighting,
+CLI parsing, tests, the harness search/calibration, and docs. No renderer/engine/inventory/save/etc. Asset
+packages remain quarantined and uncommitted.
+
+## I. Updated gate recommendation
+```
+Verdict: Conditional-Pass
+Action: Defer
+```
+The three High findings are corrected and locked with tests; the Mediums are fixed; NEW-1 is disclosed. The
+gate stays **Defer** pending independent re-review and the owner-run five-player human playtests (the fun /
+comprehension half the Builder cannot produce). Do not begin M1.
+
+## J. Required reviewer action
+Independently re-check, on `fix/m0-audit-corrections`: the attribution no longer flips on 88% util and
+matches covers-served response; forecast band coverage ≥ stated confidence with honest labels; the three
+golden checksums are byte-identical and the hybrid is non-dominant; NEW-1 is genuinely disclosed and the
+owner accepts deferring it; M4–M7; and that determinism, accounting, and scope are intact. Then the owners
+run the human playtests and record the gate verdict.

+# Pre-Fix Audit Evidence (preserved)
+
+Reproductions of the three High + relevant Medium defects **before** the bounded correction pass, captured
+so the defects remain reproducible and the corrections are checkable. Reviewed commit: `beb9289`.
+
+## H1 — causal-autopsy misattribution (util-threshold flip)
+All-grill menu (Burger/Chicken/Ribeye), ONE grill cook, lunch-rush, seed 12345 (pre-fix `DiagnoseBottleneck`):
+- seats=19: grill 85.93% util, lostCap=42, lostWait=15 -> verdict "**Seating/capacity bottleneck**".
+- seats=20: grill 90.59% util, lostCap=43, lostWait=15 -> verdict "**Kitchen bottleneck ... add grill capacity**".
+
+The verdict flipped on a 1-seat change purely because grill util crossed the hard-coded 88% gate
+(`stationPressure` jumped 0 -> 4559, beating `seatPressure` 4300), while the door-loss (lostCap 43) was
+unchanged and 2.9x the wait-loss. Root cause: incommensurable pressure scores (a utilization proxy vs a
+lost-party count) compared by `Math.Max`.
+
+## H2 — discovered dominant hybrid (value chassis + Ribeye anchor)
+`Value Chassis + Premium Anchor` (Ribeye@$52 + Veggie Bowl + House Salad + Ice Cream, grill-heavy crew, 58
+seats), 300 seeds, pre-fix:
+- lunch-rush: median **-$382.50** (loses).
+- social-dinner: median **+$1518.00** vs named-best Focused Value **+$509.90** (dominates, +$1008).
+- enthusiast-evening: median **+$2207.50** vs named-best Premium Craft **+$1023.04** (dominates, +$1184).
+
+A random sweep (3000 plans) found 2 configs dominating all three markets. The harness only compared the 9
+named strategies, so its "no dominant strategy" verdict was a statement about 9 points, not the space.
+
+## H3 — systematically optimistic forecast (band never contained the outcome)
+Pre-fix `Forecaster`, contribution forecast vs actual across 8 seeds:
+- Focused Value / lunch-rush: forecast covers **135** (actual mean ~98), forecast contribution **$1213.75**,
+  band [$845.79 .. $1581.71] "77% confidence" -> **0/8** actuals inside (all below the low bound).
+- Balanced Competent / social-dinner (committed example): forecast **$1980.52**, band low $1330.29, actual
+  mean **$273.81** -> **0/8** inside. Contribution ratio ~7.2x high.
+- Across the 27-cell matrix: contribution over-predicted in every cell; band coverage 0/8 in 24 of 27 cells.
+
+## M4 — CLI price parsing via double lost cents
+`(long)(double.Parse("0.29") * 100)` -> **28** (should be 29); `"19.99"` -> **1998** (should be 1999). ~40%
+of common two-decimal prices lost a cent; no `InvariantCulture`.
+
+## M5/M6 — test-guard gaps (mutation testing)
+- FIFO->LIFO station-queue mutation was caught ONLY by the golden checksums (no behavioral test); dequeue
+  inversions FIFO 0 vs LIFO ~47.
+- Zeroing labor cost was caught only weakly (goldens + 2 balance tests; the reconciliation identity stays
+  true when labor=0).
+- The no-float reflection guard scanned only instance fields; a `static double` field / `double` property
+  slipped through undetected.
