From 886910e3f32f58ec5d06c648174752b2be226d14 Mon Sep 17 00:00:00 2001 From: "Restaurant Builder (Claude)" Date: Wed, 29 Jul 2026 21:24:05 +0200 Subject: [PATCH 1/6] docs: lock M0 demand-rewrite contract; record failed v1 consideration prototype Design lock for the menu-responsive demand rewrite (per the authorization). Records the failed prior fixed-arrival assumption, the new consideration->captured-demand model sequence, scope/non-goals, and the strategy-integrity + positioning + forecast gates. Honestly records that a v1 prototype (price-level fit x identity fit + mix-weighted draw) FAILED on held-out seeds (mixed dominator still won all markets; focused plans got weaker) and was reverted. The load-bearing risk is the coupled occasion/positioning-coherence deterrent + calibration, which exceeds a single session. Branch + contract + evidence are the handoff; no rewrite PR opened (not ready).

The load-bearing +design is the **coupled second piece**: an occasion/positioning-coherence term where a market's *occasion* +(derived from the pool's own parameters — budget distribution, patience, not the market name) rewards a +restaurant that is a *clear fit* for that occasion and gives a muddled cheap+premium offer only a partial draw +from each pole, so a **focused** restaurant captures more of its pool than the mixed one — while a mixed +restaurant still wins the market whose occasion *is* "moderate/varied" (social). Calibrating this to (a) drop +the mixed generalist below the 10% band, (b) keep mixed viable in social, (c) not punish mixed arbitrarily, is +the crux and the likely stop point if the model cannot be made to work. + +**Estimate:** ~24-40 focused hours across the six workstreams (offer, consideration/arrival, forecast funnel, +causal attraction layer, search, docs). Critical path = consideration/arrival model + calibration (highest +uncertainty). This exceeds a single builder session; the branch, contract, and v1 evidence are the handoff.

So the poles' consideration rewards +**focus** (a menu centered on them); social's rewards **variety** (range across courses/price tiers). A mixed +value+premium menu has diluted pole-focus (its suitable-draw is split) but high social variety → it wins +social and loses both poles. A focused value/premium menu has high pole-focus but low variety → wins its pole, +loses social. Breadth itself is never taxed: a broad-but-affordable menu keeps high value focus; only splitting +toward the *opposite* pole dilutes positioning, which is legitimate occasion mismatch, not a variance penalty. + +## Adversarial pre-implementation check (main-loop, standing in for Sub-Agent B) +Quant on the load-bearing skim (lunch-rush): pool ≈ 78 value / 30 social / 12 enthusiast parties. +If focused-value captures ~28% of value vs mixed ~12% (share-diluted), focused gains ≈ 12.8 value parties +(~$180 contribution) while conceding ≈ 0.9 enthusiast parties (~$55 skim).

NOTE: base 900000 +has now been TUNED against across R3–R5, so it is exposed; final validation must use fresh held-out seeds (§14). + +### R6 HELD-OUT ROBUSTNESS (the honest verdict) — fresh, untuned seed bases +Ran the full frontier search on the tuning base and three FRESH held-out bases (each 40 seeds): + +| base | worst-market regret | dominator (<=10%)? | +|---|--:|:--:| +| 900000 (tuning; exposed by R3–R5) | 17% | no | +| 271828182 (held-out) | 6% | YES | +| 161803398 (held-out) | 9% | YES | +| 141421356 (held-out) | 13% | no | + +**Held-out median ≈ 9%; the cross-market dominator survives on 2 of 3 fresh bases.** The 17% on the tuning base +was partly overfit. So Candidate 1 does NOT robustly clear the universal-generalist gate. The surviving +generalist is a premium bistro ({Roast Chicken, Ribeye, Risotto} at moderate-premium prices) that sits within +~6–13% of the frontier in every market. Root cause (now firmly established, economic not demand-side): social & +enthusiast diners order multi-course PREMIUM checks (~$100), so a premium-anchored generalist serving even the +small premium slice present in every pool rivals value throughput. Menu-responsive demand shrinks this a lot +(frontiers are now distinct regimes — value wins lunch, premium wins enthusiast, mixed/premium wins social — and +the model is manipulation-resistant and legible) but cannot fully close it without extreme value-heavy fixtures +(gate-chasing, declined) or an economic rebalance of value-vs-premium margins / the excluded systems +(reputation, repeat visits). + +### Manipulation suite (§15) — PASS +Consideration (V/So/E), name-agnostic: pure-premium 100/6718/7784; premium+1filler 343/9731/7436; +premium+3filler 395/9825/7451 (cheap fillers cannot disguise an expensive menu → value stays ~4%); +value+never-ordered == pure-value exactly (zero influence); value+1anchor 2579/10000/5483 (< pure-premium E +7784, so one anchor gives SOME not FULL premium draw, and adding it COSTS value diners → the value-chassis +exploit is penalised); broad-all-12 2433/10000/7259 (breadth ≠ full capture of every segment). Effects are +price-LEVEL (mean), not price-VARIANCE — not a forbidden variance penalty. + +### Why no composition candidate (C1–C4) can close it — decisive argument +Consideration is deliberately market-name-agnostic (§13): a menu's per-segment consideration is IDENTICAL in +every market; only the pool weighting differs. So a premium menu attracts the same FRACTION of whatever premium +slice a market's pool holds, and (premium covers earning ~5× via multi-course checks) profitably serves that +slice everywhere. The generalist's cross-market regret is therefore fixed by (pool mix per market) × (per-cover +economics) — BOTH outside the demand model. No composition candidate changes it. Closing the 10% gate robustly +requires either an extreme value-heavy lunch pool (~95%+ value; gate-chasing, declined) or an economic rebalance +of value-vs-premium margins / the excluded systems (reputation, repeat visits). This satisfies §22's +"identify whether the product question requires an economic rebalance / broader redesign" and is why the +candidate sequence is concluded at C1 rather than grinding C2–C4 against a proven wall. One principled fixture +adjustment WAS made (lunch pool 65%→82% value, matching its "value-heavy" description) which achieves 3 of 4 +gates; going further to force the 4th is the gate-chasing I decline. + +### VERDICT (this candidate) +The demand approach is correct and nearly sufficient: it establishes menu-responsive demand and distinct +per-market regimes and passes the value-lunch, enthusiast, mixed-social, and manipulation gates, but the strict +"no plan within 10% in every market" gate is borderline-MISSED on held-out seeds (~9% median). This is a +Conditional-Pass with a precisely-bounded residual whose cause is economic. Recommended action: open the PR for +independent review + an owner decision (accept the borderline all-rounder, pursue a targeted economic rebalance, +or accept a strongly value-heavy lunch). Per §22 the residual points to "economic rebalance / different content +structure," NOT to abandoning the demand model. + +### R3 authoritative frontier search (held-out) — ROOT CAUSE isolated +The lunch-rush **frontier plan is itself premium** ({Roast Chicken@$41, Ribeye@$82, Risotto@$44}, $2552). +Best generalist within **9%** everywhere → DOMINATOR still exists. Root cause is now provable and is NOT a +demand-model defect: the lunch pool (65% value = 78 parties ≈ 125 value covers max × ~$16 ≈ $1400 ceiling) +lacks the value volume to out-earn skimming its 35% premium slice at ~3× margin. Under menu-responsive demand a +premium menu can *ignore* the value majority and profitably serve the premium slice in **every** market — the +mirror image of the old fixed-composition dominator. **Distinct per-market winners require genuinely distinct +pools.** A market billed "value-heavy, high-volume" with only 65% value and 120 arrivals is not value-heavy +enough for a value operation to win. Fix under test (R4): align the lunch pool with its stated identity +(value-heavy, high-volume).

Print the actual searchBaseSeed and note that --seeds is search-independent; add a NOTE that the best-generalist regret is seed-base-dependent and straddles 10% (read the distribution, not one run's binary verdict). Fold the pooled 7-base regret sweep + the independent-verification result into the report §C. No model/behavior change.
