If a one-app assumption had been violated, prove would +have crashed. + +**Phase 8 (VK pin update) — not needed yet.** The pin script +(`barretenberg/cpp/scripts/test_chonk_standalone_vks_havent_changed.sh`) compares +VKs derived from *pinned bytecode* (frozen msgpack from S3) against pinned VKs in +the same msgpack. It catches C++-side bb regressions, not Noir-side circuit +changes. Our changes are Noir-side, so the pin test still passes on this branch +without intervention. The pin will need updating when init_3 stops being +flag-gated and becomes the default — at that point newly captured pins will +include init_3 steps, and the reference msgpack on S3 should be rotated. + +## Follow-up opportunities + +In rough order of payoff: + +1. **`inner_3`** — the next obvious win. The deployment flow has 6 apps; init_3 + collapses the first 3 but the remaining 3 still go through 3 inner kernels. + An inner that batches 3 apps would collapse those, saving another ~2 prev-kernel + HN verifications. Same shape as init_3 but for the middle of the chain. + +2. **Skip inner kernels entirely when init_3 absorbs everything.** Marked with + `WORKTODO(luke)` at the bottom of the init_3 branch in + `private_kernel_execution_prover.ts`. If `executionStack.length === 0` after + init_3, the chain can go directly to reset+tail. The protocol-circuit + ALLOWED_PREVIOUS lists already accept init_3 as a predecessor of + reset/tail/tail_to_public, so this is purely an orchestrator change. + Relevant for short flows like transfer_0. + +3. **`init_2` / `inner_2` / `init_1` / `inner_1`.** Round out the variant set so + the orchestrator can pick the largest batch that fits. Today the dispatch is + binary (init_3 if ≥3 apps, else init); a graceful fallback through init_2 + would help any flow with exactly 2 apps. Probably low priority — most real + flows have 3+. + +4. **Generic `PrivateKernelInitNCircuitPrivateInputs`.** The TS class is + currently concrete (three explicit `privateCallN` fields). When a second + variant lands, generalize. + +5. **Remove the `PXE_USE_INIT_3` flag.** Once a few weeks of green CI confirm + stability, the flag and its `totalAppCalls >= 3` gate can collapse into + unconditional use. Coordinate with Phase 8 (pin update) at that point. + +## Known papercuts + +- **`find-bb` defaults to `bb-avm`** (`AVM=1`). Rebuilding only the non-AVM `bb` + target leaves a stale `bb-avm` and downstream bootstraps keep failing with the + same error after the supposed fix. This is now documented in + `barretenberg/cpp/CLAUDE.md`. +- **`SKIP_STEP_COUNT_CHECK=1`** is required when running client_flow tests with + `PXE_USE_INIT_3=1` because the `captureProfile` `expectedSteps` assertion is + hard-coded for the standard init+inner chain.
