Four recipes as match arms, each calling one shipped primitive directly: observe/fold (Quorum::observe), finite-product interrogation (Quad8::fold_product), Moore interrogation (Morton8x8::checked_offset + PalettePerturbation::hop over Register128), and counterfactual removal + revision (GadamerRevision::revise, run twice). A thread-local counting allocator shows every recipe runs with zero allocations, so no instruction vector is built (plan §12). ProbeRecipe is its own type and is never converted into a shipped recipes ID; the ordinal meanings are a scaffold, not canon. No Pearl projection (P7) and no selector (P6). 6 tests (zero allocation, per-primitive oracles incl. all 16 lanes / 84 visits, counterfactual runs or reports NotRun, input separation, replay, namespace), 4 disable runs red.

Codex review: removing an encounter's new roots always defeats IncreaseEligible, because GadamerRevision grants it only when a new root exists, and the resulting projection does not depend on the roots. The attack could only ever report Necessary, so it tested nothing. R3 is now revision only: its verdict stays NotRun (never acceptable) and its resulting horizon is the replay-visible output. A sweep test pins why the removal is not a counterfactual; a real attack needs structure linking roots to claims, which is P7. Disable runs: claiming Necessary and bypassing the revision output both turn the R3 test red.

374-374: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick winKeep measured work observable in optimized tests.
The counting closure returns a value, but both measured results are discarded. Rust permits unused allocations to be eliminated, and the unused
Outcomedoes not force the recipe computation to remain. The warm-up can therefore report zero allocations, and the recipe checks can pass without exercising the recipe.Use
std::hint::black_boxfor the measured inputs and outputs:Suggested fix
- let (_, warm) = counting(|| Vec::<u8>::with_capacity(1)); + let (_, warm) = + counting(|| std::hint::black_box(Vec::<u8>::with_capacity(1))); assert_eq!(warm, 1, "the counter must see a plain allocation"); for recipe in ProbeRecipe::ALL { - let (_, n) = counting(|| recipe.run(ctx)); + let (_, n) = counting(|| { + std::hint::black_box(std::hint::black_box(recipe).run( + std::hint::black_box(ctx), + )) + });
black_boxis best-effort, so the allocator counter cannot provide an absolute guarantee that an allocation reaches the global allocator.🤖 Prompt for AI Agents

…n check CodeRabbit review: - Revised kept only claims and roots, so it could not seed the next revision. It now carries the whole resulting InterpretiveHorizon, and the test replays the same encounter from it: with the first revision in the ancestry the second reading is an echo (no new root, index 2), while replaying from the prior loses the earned root. - The allocation check now black_boxes the warm-up allocation and the recipe input and output, so an optimized build cannot drop the measured work. Verified: an op list in R1 is still caught in debug and release. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01DgxrCafsJuAahpBs7oC14R
SelectorPolicy::select is a pure const fn over a declared four-fact EpistemicState (observations pending, frontier bounded, local disagreement, new encounter). V1 follows the plan §11 order (fold, bound, local, revise) and rests only when nothing is open; V2 swaps two steps to show that a policy change is a new version (they differ on 2 of 16 states). A recorded Selection (policy + state) replays to the same recipe from the record alone, even when the current default changes. The version covers selection only; tying recipe implementations to it (the plan §13 semantics digest) stays open. Recipe ordinals and the V1 order are a scaffold; ProbeRecipe is not a shipped recipes ID. 5 tests (V1 table oracle on all 16 states, purity across call order, recorded replay incl. a state where V1 and V2 differ, every cycle rests in one step per open condition and replays, only the settled state rests), 5 disable runs red.

A thread-local counting global allocator; every recipe runs in a measured window and must allocate zero times. Collecting any op / coordinate / pair list first shows up as an allocation (disable run D1).
Scope limits
ProbeRecipeis its own type and is never converted into a shippedrecipes::RecipeID (plan §12 collision); a test shows ordinal 0 has no shipped recipe and ordinal 1 names an unrelated one.NotRun, never acceptable). Revising again with the encounter's new roots removed is tautological:GadamerRevisiongrantsIncreaseEligibleonly with a new root, and the resulting projection does not depend on the roots. A sweep test pins this (Codex review). A real attack needs root-to-claim structure; that, the Pearl 2³ projection and band permission are P7. The selector is P6.Tests (7) and disable runs (6, all red)
