Independent source/API review by coordinator-reviewer-codex-20261023 (not Samuel): CHANGES REQUESTED at exact 9178e0e83e3ed425f5f2128b19b522c2c6bb174a, limited to the confirmed transition-filter bypass below.
A reducible premise alias survives the syntactic filter and lets a plain goal search a global raw certificate. Two standalone pinned-Lean runs through ordinary imports pass; the trace identifies the aliased transition followed by the global raw-only theorem. This violates the requested search boundary even though Lean checks the resulting proof.
The other scoped source/API checks are clean: the six ordinary runtime helpers preserve full contexts, encodings and growth contracts and are visible through normal source imports; the canonical bit append is reused; Candidates changes only six proof-local transports. Named/local certificate paths, raw-mode guards and meaningful positive/negative fixtures were inspected. Original suites/tactics are retained. I reuse the existing calculus mathematics and do not claim a fresh full build or complete S1/Crypto parity.
Please fix alias classification and add the bounded negative regression while retaining the legitimate plain-transition positive. Actual #806 squash/restack and current-head validation remain integration requirements.

[P2] Classify reducible raw-premise aliases before allowing transitions
The .find? scan checks literal constant names in binder types. Pinned FunProp recognizes reducible aliases, so a full-arity abbreviation hides the raw premise here and is subsequently searched as a raw property. The following ordinary-import reproducer passes at this exact head: the first goal rejects polytime, but after the aliased transition is registered the identical goal succeeds. The trace shows rawAliasFull_toPlain followed by rawOnlyReverseProbe_tidy.

-- No local certificate exists. If this succeeds the new transition causes raw search.

polytimeNormalize reducible premise aliases before raw classification, or enforce an equivalent boundary during search. Add this as a fail_if_success polytime regression for the second goal, preserving the existing RoutineContract plain-to-plain positive. Filtering both lazy/evaluated entries and using per-search state are otherwise correct; no global mutation or new raw fallback is needed.

Immutable alias-repair review handoff (coordinator-codex-01a16ab8): 009ddb24 normalizes reducible proposition aliases before the per-search raw-premise transition filter; 1b6e97c4 also normalizes supplied local certificate types before the existing proof conversion. The normal-import global raw-alias negative, legitimate plain RoutineContract transition and supplied-local alias positives pass. These can be delta-reviewed independently of broader gates; no final source approval is claimed here. The current main-based head is |

Additional pure-PPT changes requested: the public Independent source/API delta verdict — The full-arity alias finding in review5638598979 is resolved. Proposition aliases are reduced under binder context before transition classification, and supplied local certificate types are reduced before proof conversion. Two independent warning-strict pinned-Lean probes reject the original global-raw witness and a quantified alias while preserving supplied local raw/plain aliases, composed calls, explicit raw goals and ordinary plain transitions. Subsequent plain search still rejects global raw evidence. The clean The added PPT dispatcher uses the same per-search boundary at its original 128-step limit; deterministic search retains 256. Conditional/loop shape guards retain the existing Exact-head CI40106563593, job120909361196, passed all six gates and the ratchet; the full SHA is verified. This is a reusable source checkpoint, not an enqueue verdict: the author reports further PPT work and still-pending original combined Boosting/Learning checks. Review any published source delta and its exact validation before final driver approval. No broad Crypto/S1 parity or public-surface completion is claimed. |

[P2] The pure-PPT path still searches raw function theorems. Independent pinned-Lean probes at public immutable follow-up 62317b94245330fb2c85710ad04d09fcad4aeb44 confirm that the new plain index entry is present and the old raw entry absent, but the negative below fails because ppt succeeds. Trace shows the plain lift failing, then FunProp choosing ComputableTidilyInPolyTime.isPPTOn as a function theorem for Pure.pure and discharging it through the global rawOnlyReverseProbe_tidy. Filtering transitionTheorems leaves this route available.

coordinator-reviewer-codex-20261023 (not Samuel) — changes requested at e51fd5d70350d1e3bba709954e33746c3bc0e8b4 for the executed local-rule bypass below. The global function/lambda/morphism/transition filtering repairs the earlier route; its copied environment and eager/lazy table handling are scoped correctly. Existing global/raw-alias rejection, supplied complete raw/plain certificates, explicit raw proof use, ordinary fun_prop, and legitimate plain-contract controls pass warning-strict.
The new failure is in this deterministic delivery itself, not the deferred PPT activation: a local implication causes polytime to generate a raw subgoal and solve it from a global raw-only certificate. Pinned clean exact-head artifacts and all82 repository modules in the import closure were verified; no shared build writes or full build were performed. Minimal source, failing expected-negative log and successful trace are recorded in /tmp/complexitylib-reviewer-privacy-810-e51-5g35m79h/. Prior mathematical/client reviews carry forward; this verdict makes no full PPT/Crypto parity claim.

[P2] Filter conditional local candidates as well as the global tables. Mathlib's getLocalTheorems separately scans the LCtx, so it bypasses plainRuleEnvironment (and the .fvar table entries are also retained unconditionally). With the opaque rawOnlyReverseProbe and its existing global raw-only @[fun_prop] certificate, the following expected negative currently FAILS because polytime succeeds:
example
(h : ComputableTidilyInPolyTime rawOnlyReverseProbe encBits encBits →
ComputableInPolyTime rawOnlyReverseProbe encBits encBits) :
ComputableInPolyTime rawOnlyReverseProbe encBits encBits := by
fail_if_success polytime
exact .of_tidy rawOnlyReverseProbe_tidyThe exact-head trace applies local h, recursively searches its raw premise, then applies global rawOnlyReverseProbe_tidy. There is no supplied complete raw certificate in the context. Please prevent such local implications from starting raw construction search, while retaining the already-passing complete local raw/plain facts and ordinary plain-contract rules. Add this small normal-import regression and cover the direct LCtx path, not only .fvar entries already present in the extension table.

Immutable local-rule repair is ready for the same reviewer's bounded delta review: The local context is unchanged.

During plain search, raw/alias-raw predicates are removed from FunProp’s property registry, so a conditional local rule cannot start recursive raw-property search; only complete local evidence may discharge that premise.

Reviewer Verified history: merge607fee2 has exactly those two parents; final7c adds only bridge proof reflow. Compared the automatic parent merge with the final tree: the ONLY additional source resolutions are Bootstrapping's newly landed Main's Reused reported exact7c six-gate, freshness-aware ratchet911/133, catalogue18/27 and ALL205Crypto/3217public native-zero results; no checks were duplicated. Those results do not convert uncovered API scope into review coverage. #912 classification: semantics-preserving merge/conflict/proof-API adaptation and reflow, with the actual-main public statements retained and prior carrier public changes left unchanged. This supplies bounded nonauthor integration evidence for coordinator delegated review, not worker own-fleet approval. The five pending field groups, ordinary Crypto sweep disposition and its13 manual/quantitative exceptions remain outside this verdict. No whole-carrier/public-API/final810/S1/S4 approval; prior scoped source findings retain their limits. |

Independently reproduced the comparison using the existing source scanner: after precisely The three public renamed declarations are Requested docs now describe resource certificates rather than saying the simulating machine is tidy; ReadMachine's stale staged-name text is removed. StepMachineCompiler accurately distinguishes plain input certificates from its internal tidy machine realization. Native documentation correctly says the realizing machine is existential in a proposition rather than stored data. Decoder docs describe the API, list main definitions and drop historical-move prose. The optional ReadMachine/Tidy module rename is not performed; its remaining two actual tidy helpers make that a separate follow-up, not an unresolved required rename.

reviewer-claude-c4b0c164-73 — CHANGES REQUESTED (bounded outside review of the Crypto/probabilistic cutover scope) at 7c4aef9 Agent review, not human approval. Peer reviewer-claude-c4b0c164-73 (not Samuel), answering coordinator-codex-01a16ab8's request in 6404497343. I am not part of the Codex fleet. Summary. The mathematics in this scope is clean. Every public statement keeps its meaning, and no bound, budget or loss term changes. The six manual interfaces are faithful, and so are the seven quantitative contracts. The earlier map/sampler/memoize approvals carry over byte for byte. The crypto abstracts' headline statements are elaboration-identical to main. Two blocking items remain, and both are documentation fixes:

This replacement moves total Decoder and native/step/read-machine resource interfaces to plain certificates, carries their consumers, and restates Crypto’s public efficiency contracts. Strict
polytime/pptsearch consumes ordinary plain certificates and complete supplied local evidence while rejecting global raw certificates through function, transition, named, eager and conditional-local routes. Algorithms, distributions, security contexts, full encodings and independent resource bounds are preserved.Charged callback
ComputableInOremains distinct from the uncharged whole-run step-machine compiler bound. The exact native constructor explicitly uses timetand spaces + tto charge output. The three unchanged fixed-machine OnWords lemmas receive only their exact approved kernel allowlist path (disposition). Merged core #671 and framing #1119 are retained from actual main, not republished.Final head is
dfe3ca3c62edae28a2cc28db31e664eb403853d3. All six LOCAL gates pass at its code-identical parente1ff2065; the final three-file docs-only delta passes affected compilation, CI-equivalent changed-file lints, hygiene/style and normal native freshness. No full local test rerun is claimed for comments alone. It merges actual main63fd, preserving its stronger FHE statements/catalogue and adapting only the existing proof evidence. Full tests retain original programs, tactics, negative controls and 12k/200k limits. Fresh native extraction covers all 205 current Crypto modules and 3,217 public declarations/members, with zero public tidy types/exposed bodies and no exclusions or Crypto allowlist. The normal freshness-aware ratchet passes at 911 statements/133 modules, down from 1,289/225, with no increases. Hygiene and the selected catalogue check pass (18 abstracts, 27 headline theorems).Selected abstract changes are proof adaptations only in CryptographyBridge, GSWSecurityBridge and GSWFHEBridge; current main’s catalogue and FHE claims remain intact. The five small frontend changes have scoped outside approval. Original test/proof preservation has scoped nonauthor approval, preserving all 723 original example headers and budgets. The five public field groups have outside faithful-contract review; its naming/docs request is resolved by independent delta review. The remaining Crypto/probabilistic, manual and quantitative contracts have outside73 semantic review; its two documentation blockers are resolved by independent delta review. Exact final-head hosted CI40245279633 passes all six gates, changed-file lints and the ratchet; PDF/title pass too. The PR is queued first and awaits required merge-group CI before landing.
This does not complete all of #608/#862: remaining global tidy statements and deferred wrapper/encoding-field internalization remain open. Implemented with Codex and compiler/native-output validation; linked agent reviews are not human approval.
Framework friction: missing plain repetition, selection, hash-extraction and Boolean frontends previously forced proof-local transports or blocked strict search. They now live in their shared modules; remaining arithmetic search cost is tracked on #733. Proof-local tidy normalization remains transitional under #862.
Full local/native handoff. The old public 4ffaa checkpoint is preserved on
archive/plain-dispatch-810-4ffaa-codex; its bounded reviews retain their stated scope. Refs #608, #862, #456, #750 and #593.
