Review comments at @crates/warp-core/src/trusted_runtime_host.rs:
- Around line 4391-4414: In the recovery validation flow, cache each Action
outcome’s invocation bytes and inspected result during the loop that builds
`basis_obligations`, indexed alongside `echo_operation_action_outcomes`. Update
the `BasisObligation::Action` arm to reuse that cached result instead of looking
up the submission and decoding and inspecting it again; preserve the existing
sort key and error behavior.
Review comments at @docs/topics/WAL.md:
- Line 250: Update the validation description in WAL.md to state that the first
sweep checks receipt and Action basis obligations, including delayed and
cross-worldline bases, while the second sweep reconstructs composite Tick
decisions from scheduler Tick parents. Keep the description of ordered cursors
and raw retained decision order accurate.

Code Lawyer current-head audit: ba3bc2e.
The full diff and recovery/replay/publication paths were inspected. Retained decision ordering, initial/checkpoint admission, root/commit verification, target values, Action results, and conflict checks remain required. Current-head guarded Docker evidence:42 Action pipeline tests, strict feature-lib Clippy, fmt and whitespace pass; directly relevant provenance/playback suites and default compile passed in the earlier required gate. All candidate code files match the final source manifest. Documentation accuracy was checked in its canonical owners. Limits: counters measure logical data, not RSS; hashing and simulation still depend on graph size. Agy's raw feedback includes overly broad zero-RSS and signed-receipt wording; those claims are not adopted. Production numeric work counters remain. Retained logs are hash-bound evidence, not signed attestations. No benchmark timings or power-loss proof are claimed. Exact-head agy APPROVE includes its mandatory checklist. All actionable findings are addressed and published. Merge remains contingent on the live CI, head, review-thread and repository-protection gate. |

Closes #757.
Action WAL recovery cached a complete state at every basis tick and replayed each uncached prefix. The validator now indexes exact basis obligations, visits them in worldline/tick order, then verifies ordered composite Tick parents with one reusable cursor per worldline. It retains exact preparation evidence, preserves raw protocol order and all admission/basis/root/commit/result/conflict checks, and discards transient simulation states.
The deterministic regression covers a growing detached-cell history and a delayed stale-basis Action, then reopens a fresh host and verifies every value and refusal. Parent RED for eight ticks measured 28 replayed patches and nine private states; the repaired witness enforces at most two history sweeps and one cursor plus one transient simulation for that worldline. Counters measure actual successful replay applications and logical retained node/history/atom data, not process RSS or elapsed time.
Docker validation: focused regression and all 42 Action pipeline tests passed; 38 provenance replay/checkpoint tests and eight playback tests passed; strict feature-enabled library Clippy, default-feature compile contract, workspace rustfmt and whitespace checks passed. The final integration with main preserves #762 root semantics, #765 caller paths, and #766 bounded summaries. No original study timing measurements were reproduced.
Canonical WAL documentation and CHANGELOG describe the new private recovery algorithm and its limits. Full-state hashing and Tick simulation can still have graph-dependent cost. No persisted schema, package meaning, causal authority, or native application callback changes.
