Everything else should import from upstream crates (e.g., `continuations_v2`, `recursion_circuit`, `openvm_*`). Remove local duplicates once upstream can be used again. +2. **ZKVM Proof First** – New APIs accept `ZKVMProof>` instead of OpenVM `Proof`. Provide adapters (currently `unimplemented!()` or TODO stubs) that convert into OpenVM structures right before trace generation. +3. **Recursion VK Alias** – Replace `Arc>` with `Arc>>` wherever the “child VK” travels (constructors, traits, agg prover logic). Introduce a local alias (e.g., `type RecursionVk = ZKVMVerifyingKey<…>`) to keep signatures readable. +4. **Trait Copy Rule** – Only fork upstream definitions when the child-VK type must change. For example, copy `VerifierTraceGen` locally (because it takes `MultiStarkVerifyingKey`), but keep using upstream `VerifierConfig`, `VerifierExternalData`, and `CachedTraceCtx` directly so we don’t duplicate logic unnecessarily. +5. **Comment, Don’t Delete** – When slicing out unused functionality (compression/root/deferral), comment or `unimplemented!()` the sections you can’t finish yet so the call graph remains visible. + +## Workflow + +### 1. Identify Needed Forks +- Search upstream `openvm/crates/recursion` + `continuations-v2` for `MultiStarkVerifyingKey`. +- For each reference used by our code paths (“inner” continuation only right now), copy the minimal module into `ceno_recursion_v2/src/system` (mirror the original file layout). +- Replace imports to point at the local versions before editing types. + +### 2. Introduce Recursion VK Alias +- In `inner/mod.rs` (and any copied traits), add: + ```rust + type RecursionVk = ZKVMVerifyingKey>; + ``` +- Update struct fields, constructor args, and helper signatures to use `Arc`. +- Where OpenVM still needs a `MultiStarkVerifyingKey`, create helper methods like `fn as_openvm_vk(&self) -> Arc>` that currently `unimplemented!()` until the translation exists. + +### 3. Keep Upstream for Everything Else +- Circuit/AIR definitions, tracegen impls, transcript modules, and GKR logic should stay imported from upstream crates unless the type change forces a local copy. +- When copying files, preserve module paths (e.g., `system/mod.rs`, `system/verifier.rs`) so future diffs with upstream stay manageable. + +### 4. Testing & Proof Artifacts +- Unit/integration tests should load `Vec>` from `./src/imported/proof.bin` (and `vk.bin` when needed) using `bincode::deserialize_from`. +- Use the concrete engine alias `type E = BinomialExtensionField` / `type Engine = BabyBearPoseidon2CpuEngine`. +- Until the bridge is implemented, leave test bodies `#[ignore]` with `unimplemented!()` placeholders after deserialization. + +### 5. Cargo Hygiene +- Whenever new upstream crates are referenced (e.g., `verify-stark`, `continuations_v2` modules), add them to `ceno_recursion_v2/Cargo.toml` with the `develop-v2.0.0-beta` branch pin. +- Run `cargo check -p ceno_recursion_v2` (since the crate is excluded from the root workspace) after each major type tweak. + +## Reference Paths + +- Local system overrides: `ceno_recursion_v2/src/system/**` +- Continuation prover overrides: `ceno_recursion_v2/src/continuation/prover/**` +- Upstream mirrors: `/home/wusm/.cargo/git/checkouts/openvm-*/ac85e71/crates/...` +- Serialized artifact expectations: `./src/imported/proof.bin`, `./src/imported/vk.bin` diff --git a/ceno_recursion_v2/skills/ceno-recursion-principles/agents/openai.yaml b/ceno_recursion_v2/skills/ceno-recursion-principles/agents/openai.yaml new file mode 100644 index 000000000..7f6fea8b7 --- /dev/null +++ b/ceno_recursion_v2/skills/ceno-recursion-principles/agents/openai.yaml @@ -0,0 +1,4 @@ +interface: + display_name: "Ceno Recursion" + short_description: "Guidelines for Ceno recursion refactors" + default_prompt: "Follow the Ceno recursion refactor principles."

Replace `Arc>` with `Arc>>` wherever the “child VK” travels (constructors, traits, agg prover logic). Introduce a local alias (e.g., `type RecursionVk = ZKVMVerifyingKey<…>`) to keep signatures readable. 4. **Trait Copy Rule** – Only fork upstream definitions when the child-VK type must change. For example, copy `VerifierTraceGen` locally (because it takes `MultiStarkVerifyingKey`), but keep using upstream `VerifierConfig`, `VerifierExternalData`, and `CachedTraceCtx` directly so we don’t duplicate logic unnecessarily. 5. **Comment, Don’t Delete** – When slicing out unused functionality (compression/root/deferral), comment or `unimplemented!()` the sections you can’t finish yet so the call graph remains visible. +6. **Mirror Private Upstream Shims** – If recursion modules need items that upstream marks `pub(crate)` (e.g., `system::frame` or `POW_CHECKER_HEIGHT`), copy the minimal shim into this crate so future diffs stay aligned while letting the fork compile. ## Workflow diff --git a/ceno_recursion_v2/src/continuation/prover/mod.rs b/ceno_recursion_v2/src/continuation/prover/mod.rs index f4237bfb3..b845a9404 100644 --- a/ceno_recursion_v2/src/continuation/prover/mod.rs +++ b/ceno_recursion_v2/src/continuation/prover/mod.rs @@ -1,14 +1,13 @@ -use continuations_v2::{ - RootSC, SC, - circuit::{inner::InnerTraceGenImpl, root::RootTraceGenImpl}, - prover::{CompressionProver, InnerAggregationProver, RootProver}, -};

Focus on minimal forking, RecursionProof-first seams, preflight-owned replay, and strict placeholder/validation policy. --- # Ceno Recursion Principles ## Overview -This skill captures the standing orders for evolving `ceno_recursion_v2`: reuse upstream OpenVM crates whenever possible, only fork modules that must diverge (e.g., to handle Ceno’s ZKVM proofs), and keep ZKVM <> OpenVM bridge logic localized. +This skill captures the standing orders for evolving `ceno_recursion_v2`: reuse upstream OpenVM crates whenever possible, fork only where type boundaries force divergence, and keep ZKVM/OpenVM bridge logic at narrow seams. ## Quick Triggers Use this skill when: - Modifying `ceno_recursion_v2/src/system` or `src/continuation/**` -- Replacing `Proof` inputs with `ZKVMProof>` -- Swapping child verifying keys from `MultiStarkVerifyingKey` to `ZKVMVerifyingKey` +- Replacing `Proof` flows with `RecursionProof` +- Swapping child VK flows from `MultiStarkVerifyingKey` to `RecursionVk` - Copying/patching OpenVM modules (recursion/continuation) into the Ceno crate -- Adding tests that deserialize `./src/imported/proof.bin` +- Debugging trace/air mismatches during continuation proving ## Core Principles -1. **Minimal Divergence** – Keep local copies only for code directly touched by the refactor. Everything else should import from upstream crates (e.g., `continuations_v2`, `recursion_circuit`, `openvm_*`). Remove local duplicates once upstream can be used again. -2. **ZKVM Proof First** – New APIs accept `ZKVMProof>` instead of OpenVM `Proof`. Provide adapters (currently `unimplemented!()` or TODO stubs) that convert into OpenVM structures right before trace generation. -3. **Recursion VK Alias** – Replace `Arc>` with `Arc>>` wherever the “child VK” travels (constructors, traits, agg prover logic). Introduce a local alias (e.g., `type RecursionVk = ZKVMVerifyingKey<…>`) to keep signatures readable. -4. **Trait Copy Rule** – Only fork upstream definitions when the child-VK type must change. For example, copy `VerifierTraceGen` locally (because it takes `MultiStarkVerifyingKey`), but keep using upstream `VerifierConfig`, `VerifierExternalData`, and `CachedTraceCtx` directly so we don’t duplicate logic unnecessarily. -5. **Comment, Don’t Delete** – When slicing out unused functionality (compression/root/deferral), comment or `unimplemented!()` the sections you can’t finish yet so the call graph remains visible. -6. **Mirror Private Upstream Shims** – If recursion modules need items that upstream marks `pub(crate)` (e.g., `system::frame` or `POW_CHECKER_HEIGHT`), copy the minimal shim into this crate so future diffs stay aligned while letting the fork compile. +1. **Minimal Divergence** - Fork only the seam that must diverge. Keep upstream for AIRs/modules that do not require Ceno type changes. +2. **RecursionProof First** - Public APIs in local forked modules should prefer `RecursionProof` and `RecursionVk` aliases over upstream `Proof` and `MultiStarkVerifyingKey`. +3. **Bridge Locality** - Put conversion stubs and TODOs in bridge points (`system/types.rs`, local trace adapters), not spread across unrelated AIR logic. +4. **Preflight Owns Replay** - Transcript/replay ordering is computed during preflight; later blob/trace generation should consume read-only replay data. +5. **Placeholder Discipline** - Temporary mocked values are allowed only if shape-correct and tagged with explicit TODO ownership. +6. **Invariant First** - Preserve count/order invariants (`airs()` vs `per_trace`) before semantic completeness. +7. **Visible, Reversible Deltas** - Prefer small, reviewable patches and avoid broad upstream copy unless absolutely required. + +## Minimal Fork Decision Matrix + +Fork locally only when at least one applies: +- Child proof/VK type at boundary must change to `RecursionProof`/`RecursionVk`. +- Upstream item is private (`pub(crate)`) and needed in local integration path. +- Upstream interface cannot inject Ceno-specific data without invasive changes. + +Do not fork when: +- Change is only wiring/imports and can be done in local caller. +- Upstream module already supports required behavior through existing interfaces. + +When forking, keep: +- Original file/module layout for future diffability. +- Fork scope minimal (single module seam first, then expand only if blocked). ## Workflow -### 1. Identify Needed Forks -- Search upstream `openvm/crates/recursion` + `continuations-v2` for `MultiStarkVerifyingKey`. -- For each reference used by our code paths (“inner” continuation only right now), copy the minimal module into `ceno_recursion_v2/src/system` (mirror the original file layout). -- Replace imports to point at the local versions before editing types. +### 1. Establish Type Seams First +- Confirm aliases in `src/system/types.rs` (`RecursionProof`, `RecursionVk`). +- Update constructor/trait signatures at seam files before touching AIR internals. + +### 2. Keep AIR/Trace Ordering Consistent +- Ensure `src/circuit/inner/mod.rs` `airs()` order exactly matches context order produced in `src/circuit/inner/trace.rs`. +- If pre/post contexts are re-enabled, corresponding AIR entries must be present. + +### 3. Placeholder Policy (Temporary) +- If data is missing from `RecursionProof`, use deterministic zero mocks. +- Add explicit comments: `TODO(recursion-proof-bridge): ...`. +- Mocked traces must be width-correct for their AIR and satisfy basic row-0 invariants. + +### 4. Replay Ownership Rule +- Preflight computes and records transcript/replay ordering. +- Blob/trace generation should consume replay records only (no hidden replay recomputation). + +### 5. Validation Loop +- Iterate with: `cargo check` -> target test -> capture first failing reason -> minimal fix. +- Prefer turning panics into structured errors where possible for diagnosability. +- Keep temporary diagnostics narrow and removable. + +### 6. Cargo/Test Hygiene +- Run checks on `ceno_recursion_v2` after each nontrivial seam change. +- Keep target regression test command handy: + - `RUST_MIN_STACK=33554432 RUST_BACKTRACE=1 cargo test -p ceno_recursion_v2 leaf_app_proof_round_trip_placeholder -- --nocapture` + +## Acceptance Checklist for Migration PRs + +Before continuing to next module, verify: +- `airs().len()` and proving-context trace count match. +- AIR ordering matches trace ordering (pre -> verifier -> post when enabled). +- Any mocked data has `TODO(recursion-proof-bridge)` and clear ownership. +- No new broad forks were introduced without matrix justification. +- Current top blocker is explicitly identified by latest test/check run. + +## Reusable PR Checklist Template + +Copy this block into each migration PR description and mark each item as done or N/A with rationale. + +```markdown +## Migration Checklist (ceno-recursion-principles) + +### Scope and Forking +- [ ] Fork scope is minimal and justified by the decision matrix. +- [ ] Upstream modules remain in use unless a concrete seam forces divergence. +- [ ] Forked files preserve upstream layout for easier future sync. + +### Type Seams +- [ ] New/updated public seams use `RecursionProof` / `RecursionVk` where applicable. +- [ ] Bridge logic is localized (for example `src/system/types.rs` or local trace adapters). +- [ ] No unrelated AIR/business logic was modified only to pass types through. -### 2. Introduce Recursion VK Alias -- In `inner/mod.rs` (and any copied traits), add: - ```rust - type RecursionVk = ZKVMVerifyingKey>; - ``` -- Update struct fields, constructor args, and helper signatures to use `Arc`. -- Where OpenVM still needs a `MultiStarkVerifyingKey`, create helper methods like `fn as_openvm_vk(&self) -> Arc>` that currently `unimplemented!()` until the translation exists. +### AIR and Trace Invariants +- [ ] `airs()` order matches proving context order exactly. +- [ ] `airs().len()` matches proving-trace count. +- [ ] Re-enabled pre/post contexts have corresponding AIR entries. -### 3. Keep Upstream for Everything Else -- Circuit/AIR definitions, tracegen impls, transcript modules, and GKR logic should stay imported from upstream crates unless the type change forces a local copy. -- When copying files, preserve module paths (e.g., `system/mod.rs`, `system/verifier.rs`) so future diffs with upstream stay manageable. +### Placeholder Policy +- [ ] Any mocked value is deterministic and shape-correct. +- [ ] Each mocked value has `TODO(recursion-proof-bridge): ...` with ownership. +- [ ] Placeholder traces satisfy basic row-0 invariants for their AIR. -### 4. Testing & Proof Artifacts -- Unit/integration tests should load `Vec>` from `./src/imported/proof.bin` (and `vk.bin` when needed) using `bincode::deserialize_from`. -- Use the concrete engine alias `type E = BinomialExtensionField` / `type Engine = BabyBearPoseidon2CpuEngine`. -- Until the bridge is implemented, leave test bodies `#[ignore]` with `unimplemented!()` placeholders after deserialization. +### Replay Ownership +- [ ] Replay/transcript ordering is computed in preflight. +- [ ] Blob/trace generation consumes preflight replay records read-only. -### 5. Cargo Hygiene -- Whenever new upstream crates are referenced (e.g., `verify-stark`, `continuations_v2` modules), add them to `ceno_recursion_v2/Cargo.toml` with the `develop-v2.0.0-beta` branch pin. -- Run `cargo check -p ceno_recursion_v2` (since the crate is excluded from the root workspace) after each major type tweak. +### Validation Evidence +- [ ] `cargo check` run after the latest nontrivial seam change. +- [ ] Target regression test run (or explicit blocker reason recorded). +- [ ] Current top blocker (if any) is stated with file/path and first failing message. +``` ## Reference Paths -- Local system overrides: `ceno_recursion_v2/src/system/**` -- Continuation prover overrides: `ceno_recursion_v2/src/continuation/prover/**` -- Upstream mirrors: `/home/wusm/.cargo/git/checkouts/openvm-*/ac85e71/crates/...` -- Serialized artifact expectations: `./src/imported/proof.bin`, `./src/imported/vk.bin` +- Skill source in repo: `skills/ceno-recursion-principles/SKILL.md` +- Skill source in global codex dir: `~/.codex/skills/ceno-recursion-principles/SKILL.md` +- Local seam hotspots: + - `src/system/types.rs` + - `src/circuit/inner/mod.rs` + - `src/circuit/inner/trace.rs` + - `src/continuation/prover/inner/mod.rs` + - `src/gkr/mod.rs`, `src/system/preflight/mod.rs` diff --git a/ceno_recursion_v2/skills/ceno-recursion-principles/agents/openai.yaml b/ceno_recursion_v2/skills/ceno-recursion-principles/agents/openai.yaml index 7f6fea8b7..2d4faa272 100644 --- a/ceno_recursion_v2/skills/ceno-recursion-principles/agents/openai.yaml +++ b/ceno_recursion_v2/skills/ceno-recursion-principles/agents/openai.yaml @@ -1,4 +1,4 @@ interface: display_name: "Ceno Recursion" - short_description: "Guidelines for Ceno recursion refactors" - default_prompt: "Follow the Ceno recursion refactor principles." + short_description: "Migration playbook for Ceno recursion module forks" + default_prompt: "Follow ceno-recursion-principles: minimal fork matrix, RecursionProof-first seams, preflight-owned replay, TODO-tagged placeholder policy, and air/trace ordering invariants." diff --git a/ceno_recursion_v2/src/bn254.rs b/ceno_recursion_v2/src/bn254.rs index d00efa84d..bcd11dd82 100644 --- a/ceno_recursion_v2/src/bn254.rs +++ b/ceno_recursion_v2/src/bn254.rs @@ -51,4 +51,3 @@ impl From for [u32; DIGEST_SIZE] { }) } } - diff --git a/ceno_recursion_v2/src/circuit/deferral/mod.rs b/ceno_recursion_v2/src/circuit/deferral/mod.rs index 4c1d3a629..8d8ef2ace 100644 --- a/ceno_recursion_v2/src/circuit/deferral/mod.rs +++ b/ceno_recursion_v2/src/circuit/deferral/mod.rs @@ -1,2 +1 @@ pub const DEF_HOOK_PVS_AIR_ID: usize = 0; - diff --git a/ceno_recursion_v2/src/circuit/inner/def_pvs/air.rs b/ceno_recursion_v2/src/circuit/inner/def_pvs/air.rs index 7f12aab93..46b0c7c14 100644 --- a/ceno_recursion_v2/src/circuit/inner/def_pvs/air.rs +++ b/ceno_recursion_v2/src/circuit/inner/def_pvs/air.rs @@ -2,7 +2,7 @@ use std::{array::from_fn, borrow::Borrow}; use openvm_circuit_primitives::utils::{assert_array_eq, not}; use openvm_stark_backend::{ - interaction::InteractionBuilder, BaseAirWithPublicValues, PartitionedBaseAir, + BaseAirWithPublicValues, PartitionedBaseAir, interaction::InteractionBuilder, }; use p3_air::{Air, AirBuilder, AirBuilderWithPublicValues, BaseAir}; use p3_field::{Field, PrimeCharacteristicRing}; @@ -15,14 +15,14 @@ use recursion_circuit::{ prelude::DIGEST_SIZE, }; use stark_recursion_circuit_derive::AlignedBorrow; -use verify_stark::pvs::{DeferralPvs, CONSTRAINT_EVAL_AIR_ID, DEF_PVS_AIR_ID}; +use verify_stark::pvs::{CONSTRAINT_EVAL_AIR_ID, DEF_PVS_AIR_ID, DeferralPvs}; use crate::{ bn254::CommitBytes, circuit::{ + CONSTRAINT_EVAL_CACHED_INDEX, deferral::DEF_HOOK_PVS_AIR_ID, inner::bus::{PvsAirConsistencyBus, PvsAirConsistencyMessage}, - CONSTRAINT_EVAL_CACHED_INDEX, }, utils::digests_to_poseidon2_input, }; @@ -72,17 +72,15 @@ impl Air f let local: &DeferralPvsCols = (*local).borrow(); let next: &DeferralPvsCols = (*next).borrow(); - /* - * This AIR may have 1 or 2 rows.
