From a09d76f370c0fd84fdc6f3496544cbb273a37b70 Mon Sep 17 00:00:00 2001 From: tegwick Date: Fri, 31 Jul 2026 02:14:34 +0200 Subject: [PATCH 1/9] T08 iter 1: scenario runner executes; GROUND setup and Select step Replaces the RunOutcome::Unimplemented stub with a real runner: - ScenarioGame trait: games own setup presets and the command vocabulary, the runner owns execution, assertions, and determinism. - K8 double-run: every scenario runs twice on the same seed and fails on state-hash divergence. - K4/K11: applied events go through Envelope into EventLog, so seq monotonicity is enforced on the real path, not just in unit tests. - setup.patch was parsed and silently dropped; the runner now applies it generically and errors on a path that does not exist, so a typo in a scenario can never pass as a no-op. - Assertions: dot-path state lookup over objects and arrays, ordered event subsequence matching by field subset, exact rejects-set match. GROUND rules realized: GR-S01..S04 setup (seeded shuffle, deal, Lead, Surface Problem face up), GR-R02 Select commit, GR-R03 stress gate and Freedom spend, GR-A13 targeting legality. cb-sim dispatches by the scenario's game prefix and reports rule coverage. 3 scenarios pass, 7 rules covered; fmt/clippy/tests green.

Steps 1 (GROUND), 3 (DARVO stages), 4 (INVESTIGATE) and 6 (SOLVE) are not implemented yet; their Actions resolve as no-ops and no scenario claims coverage of them. - SUPPORT GR-A03/A04/A05 and ATTACK GR-A06..A09, with relation formation, flip and break per GR-L01/L03/L04 and Protection cancellation. - GR-R08 End: DARVO trigger at Stress 5 in Lead order, Lead rotation, Round advance, per-round flags cleared. - Stress clamps 0-5 on every application, the U2 default, so a mid-round spike that is reduced before End does not trigger DARVO. Two consent-dependent rules are deliberately left out because they need a decision command rather than a default: Bond formation (GR-L02) and the target's flip-or-break choice on Support-through-Rivalry (GR-A05). Both are noted in code and covered by a provisional scenario. Fixes a defect in the T07 scaffold: relations were keyed by a tuple, which JSON cannot use as an object key, so state_hash would have panicked on any state holding a relation. Relation keys are now a Pair newtype serialized as "a-b", with a regression test. setup.patch may now create a final key so scenarios can seed open-ended maps; a typo anywhere earlier in the path is still an error. 8 scenarios pass, 28 rules covered; 17 tests, fmt/clippy green.

Resolution refuses to start while any revealed GROUND lacks a mode, and only that player may choose it. - GR-A10 GROUND-GR: self -2 Stress and Freedom readied. - GR-A01 INVESTIGATE: reveal the chosen hidden non-Denied Problem, then draw one Solution; the draw still happens when nothing is revealable. - GR-A02 SOLVE: spend a Solution of the Problem's suit and claim it; a later resolver the same round spends nothing, per Lead order. - GR-A13 tightened: INVESTIGATE must target a hidden Problem, SOLVE a face-up non-Denied one. Previously any existing Problem was accepted. Deck exhaustion (U4) reshuffles the discard, seeded from the game seed and round so validate stays a pure function of state. The resulting order travels inside DeckReshuffled, so replay never re-derives it. Still pending, each because it needs its own decision command rather than a default: GROUND-OU and GROUND-ND three-way choices (GR-A11/A12) and the DARVO stage machine (GR-D02..D07). No scenario claims coverage of them. Filler picks in existing scenarios moved from GROUND to INVESTIGATE: GROUND now has a real Stress effect, which was polluting the Support and Attack assertions. 11 scenarios pass, 34 rules covered; 17 tests, fmt/clippy green.

A Bond can no longer form without consent. Each choice is validated against the state it claims to act on: a restore needs a Denied Problem, a cancel needs an Attack actually aimed at the chooser, a Blame removal needs that token present, a break needs that relation to exist. GR takes no sub-choice, and OU and ND may only use choices from their own list. GR-A09 ordering follows the U8 default: an OU cancellation is chosen at step 1 and applies first, so a Protection token is spent only when it is what actually cancels. 14 scenarios pass; AM-1 coverage 41/58 (70%), up from 34/58.

Under the U3 default no legal target is a no-op and the sequence still advances. - GR-D04 ATTACK: one extra Attack under the normal relation rules, then place the Focus token beside the target even if it was cancelled. - GR-D05 REVERSE: flip Focus to Blame, +1 Stress to the holder, one Protection to the owner, unless the holder's GROUND-ND rejects it. Under the U5 default the owner takes -2 either way and the sequence ends. - GR-D06 early end: a Support through a Bond that predates this round's Support step cancels the stage and ends the sequence, and the placed Focus token is removed. GROUND-GR ends it after the stage resolves. - GR-D07: the marker returns to OFF, so a later End can re-trigger. The Attack rules are now one routine shared by the chosen ATTACK Action and the DARVO extra Attack, so GR-A06..A09 cannot drift between them. Stage targets are named by their own command during Reveal, validated against what the stage admits: DENY needs an eligible Problem, ATTACK another player, and only a player with a live sequence may choose. 18 scenarios pass; AM-1 coverage 47/58 (81%), up from 41/58.

AM-1 at 100% - GR-R09: after Round 5's End the game ends and scoring runs instead of the round advancing. - GR-E01: claimed Problems sum their printed values against the player-count threshold (2p 5, 3-4p 7, 5-6p 9 in dataset 0.1). - GR-E02 SHARED GROUND: shared score, Mastery reduced per Blame token and per Denied Problem. - GR-E03 COMMON PROBLEM: personal score is claimed value less Blame, tiebroken by lower Stress then more Bonds. - GR-E04 BONDED COALITIONS: connected components over Bonds only, so Rivalries do not connect and an unbonded player is a coalition of one; tiebroken by lower combined Stress then fewer Blame. Ties yield every tied candidate rather than an arbitrary pick, which is what "shared victory" in GR-E03/E04 asks for. AM-1 rule coverage is now 58/58 (100%), 21 scenarios, 17 tests. Caveat recorded rather than papered over: GR-E02's "successes" is not defined in dataset 0.1. It is implemented as the count of claimed Problems and both scoring scenarios are marked provisional, so a ground-game ruling flips a scenario rather than the kernel.

Met: AM-1 rule coverage 58/58; AM-6 throughput 1.65M events/s against a 100k target; AM-7 scaling 1.08x at 20x workload and a 100k-event replay in 4.13ms against a 5s budget; AM-8 zero divergence over 10 full runs with fmt and clippy clean; AM-10 zero foreign collection types. Not met and reported as such: AM-4 at 33 transitive crates against a <=20 target. Attribution is in the evidence file. The recommended fix is making serde_yaml optional (-5, a test-only concern), after which the remainder is sha2 and rand_chacha, which K5 and K7 require. We are not hand-rolling crypto primitives to win a dependency count. AM-12 is recorded as uncomputable: per-task token counts were never instrumented, and inventing a USD figure would defeat the metric. A measurement error was found and corrected before publication. The first benchmark reported 9.3M events/s on a flat curve. The workload had a player selecting SUPPORT while parked at Stress 4, so GR-R03 rejected it, rounds never completed, and throughput was computed for rounds that never happened. The bench now asserts the per-round event count and panics rather than measuring a stalled loop. The corrected figure is 5.6x lower. The evidence file states plainly what the boardgame.io comparison does and does not support: the ~450x command-rate ratio is cross-runtime and cross-feature-set, so it is a direction, not a verdict, per the InnerLoop parity-cap rule.

Those two contracts cost 12 crates between them + and are load-bearing for determinism. A target that a spec's own + contracts make unreachable is a bad target. + +What we are **not** doing: hand-rolling SHA-256 or ChaCha to win a +dependency count.

The gap: both serious errors in the pass were measurement errors, and the loop caught neither. Review reads prose; these were claims about numbers. In both cases a harness ran successfully while doing no work — a JS harness timing rejected no-ops, and a Rust benchmark computing throughput for rounds that never completed. v1.0 adds: - Measurement validity: a harness must assert it performed the work it reports. A number from a run that cannot prove it did the work is void. - Metric feasibility: every metric names its instrument and is checked reachable against the contracts in its own spec. - No silently-ignored input; decisions get commands, not defaults; scaffolds are exercised or marked; coverage gates that count tags say so. - Evidence must state what a comparison does not support. - The chaos roll is recorded even when it changes nothing, so a mechanism that never fires is visible rather than assumed.

This is what it got right, what it +missed, and what changes in v1.0. + +## What earned its cost + +**The adversarial review (Step 2).** On its single use it produced one +blocking finding and three significant ones. The blocking one mattered: +the survey claimed boardgame.io's degradation was "architectural, not a +tuning artifact", and the challenge pointed at the `disableUndo` flag +that the claim had not accounted for. The resolution was a rerun with +undo disabled, not a rhetorical defence — degradation persisted (0.66× +at 40k, still DNF at 100k), so the overclaim was retracted and two +mechanisms were attributed separately. A survey that had gone straight +to an ADR would have carried a false claim into the decision. + +**The parity-cap rule.** It stopped the boardgame.io comparison from +being written up as a verdict. The final evidence file says the ~450× +command-rate ratio is a direction, not a verdict, and lists the four +reasons it is not like-for-like. That paragraph exists because the rule +required it. + +**Deferring rules that need a decision.** Four rules (GR-L02, GR-A05, +GR-A11, GR-A12) were left unimplemented across two iterations rather +than given invented defaults, then implemented as explicit commands. +No scenario claimed coverage of them in the interim. This is the single +most useful habit the pass produced and v1.0 promotes it to a rule. + +**The provisional mechanism.** Ten U-items with `provisional: true` +scenarios meant an underdetermined rule cost a scenario tag, not a +kernel decision. One further ambiguity (GR-E02's "successes") was found +during implementation and captured the same way. + +## What the loop missed + +**Both serious errors in this pass were measurement errors, and the +loop caught neither.** Review caught claims; nothing caught numbers. + +1. The boardgame.io harness v1 reported "8.4s for 100k moves". It was + measuring rejected no-ops — every move was refused. Caught by + noticing the error text in output, not by any gate. +2. The Rust benchmark reported **9.3M events/s on a flat curve** and + would have been published as a 93× beat of AM-6. The workload had a + player selecting SUPPORT while parked at Stress 4, so GR-R03 rejected + it, rounds never completed, and throughput was computed for rounds + that never happened. Caught only because a probe test asserted a + round produces events at all. The corrected number is 5.6× lower. + +Both share a shape: **the harness ran successfully while doing no +work**, and success was inferred from "it completed" rather than from +"it did the thing". This is the dominant failure mode of an agent-driven +loop, because an agent will happily report a fast number. + +**Scaffold code with unexercised paths.** T07 produced a compiling, +"green" workspace that contained two latent defects: relations keyed by +a tuple, which JSON cannot serialize, so `state_hash` would have +panicked on any state holding a relation; and `setup.patch`, which was +parsed and silently discarded, so every scenario using it would have +tested the wrong initial state. Both were invisible until real scenarios +exercised them. Green gates on a scaffold mean very little. + +**Metrics were specified without checking they were reachable or +instrumented.** AM-4 (≤20 crates) is unreachable given the spec's own +K5 and K7 contracts, which require ChaCha and SHA-256 and cost 12 crates +between them — the metric was written before those contracts existed and +never revisited. AM-12 (cost in USD) was specified in detail, with a +price sheet and a formula, and then never instrumented, so it could not +be computed at all.

It is retained, but v1.0 requires the roll be recorded even +when it changes nothing, so its absence is visible rather than assumed. + +**The coverage gate counts tags, not behaviour.** `make coverage` +reports 58/58 by comparing rule IDs in the spec against `covers:` lists. +It catches invented IDs and outright gaps, which is real, but a scenario +can name a rule it does not exercise. 100% on that gate is not proof +AM-1 is met, and v1.0 says so where the number is reported. + +## Changes in v1.0 + +1. **Measurement validity (new, Step 5).** Every benchmark and harness + must assert it performed the work it reports — a positive control. + A number from a run that cannot prove it did the work is void. +2. **Metric feasibility (Step 4).** Each acceptance metric names its + instrument and is checked reachable against the contracts in the same + spec.
