Final task of the spec. Ran the complete unit, integration, and soak
suite (controller_unit_test, all scheduler binaries, xcelib_test, Go
apiserver tests under both CGO_ENABLED=0/1, and every soak mode this
spec added) -- all clean, zero new job loss, divergence, or liveness
stall.
Designed and executed a genuine empirical byte-identical baseline
comparison for the non-array (array_size=1) path: built the commit
immediately preceding this spec's first commit in an isolated
worktree, deployed independent clusters from both the baseline and
current-tree binaries, and did a byte-for-byte comparison of the raw
on-disk WAL entries for an identical single-job submission.
Independently reproduced end-to-end by the reviewer with a consistent
result -- every differing byte maps to inherently run-specific fields
(timestamp/crc/jobid/sub_time), zero differences in term/lsn/type/
payload_len or the remaining ~6485 payload bytes. Corroborated by a
structural code-diff argument (the single-job WAL-encode path is
untouched, purely-additive diff only) and the pre-existing task 2.3
unit test asserting the same invariant.
Confirmed the three self-flagged residual gaps (task 3.1 bulk-insert
orphan prefix, task 4.2 boot-replay fence, task 5.3b bounded leak)
remain the complete and only set of open items across all 24
completed tasks.
Task 6.3 of job-array-single-wal-record (Requirements 8.1, 8.2, 8.4).
Overall verdict: GO. This completes the spec's implementation phase.
