F449 MULTI-ROUND REVIEW RECORD
Captured: 2026-08-25 UTC

R1 - Proof scope and soundness
Reviewed signed assumptions, exact failed-assumption cores, leaf LRUP replay,
split-tree resolution, root receipt replay, SAT assumption polarity, and Query
IR witness execution. Fixed silent assumption de-duplication and persistent
UNSAT confirmation that could otherwise lose the cube scope.

R2 - Task state machine and crash recovery
Reviewed pending/leased/sat/unsat/cancelled/exhausted transitions, monotonically
increasing fence tokens, expiry, heartbeat, retry budgets, stale completion,
and SAT peer cancellation. Added real crash-reclaim and active-peer cancellation
tests; finite timestamp validation now fails closed.

R3 - Persistent protocol and concurrency
Reviewed SQLite transaction boundaries, concurrent claim/complete/finalize,
restart reconstruction, canonical JSON, and immutable execution identity.
Fixed non-deterministic aggregate proof producers so two coordinators converge
on the same CAS object. Persisted JSON now rejects duplicate members,
NaN/Infinity, non-ASCII, oversized, and non-canonical encodings.

R4 - Service, resource, and lifecycle integration
Reviewed global cube-slot budgeting, per-slot backend ownership, parent query
lease renewal, result telemetry, independent QueryStore replay, and dependent-
first artifact GC. Added partition-execution lifecycle edges and active-state
fail-closed inventory behavior.

R5 - Adversarial tests, documentation, and claim boundary
Reviewed symlink and metadata drift, cube inventory mutation, duplicate JSON,
proof-digest tamper, negative assumptions, dual coordinator races, and E2E
one-shot/persistent backends. Documentation distinguishes mechanism evidence
from speedup, coverage, and defect-yield claims.

FINAL GATES
- Focused: 22 passed.
- Coupled regression: 143 passed, 50 subtests passed.
- Full capability gate: 1419 passed, 310 subtests passed; zero skip, xfail,
  xpass, deselect, collection error, missing nodeid, or unexpected nodeid.
- External capabilities: 16/16 present.
- Static checks: py_compile, Ruff, and git diff --check passed.
