Roadmap "Where we are" table said Baseline (G0.2) = "Not yet, run on kube" -- stale.
Record 07 (G0 exit) was completed right after on the docker lane (e901640, 1300/1300,
catch 3.3% / FP 3.1%, regex/quick-rule floor, engine_covered=0). G0 is exited; the kube
`ax` lane was never needed for the baseline. Reframed the readiness plan: steps 1-4 done,
the `ax` lane moves to G1 (engine arm at scale, gated by spec tasks 4.4/5.4).
Also fixed the ax binary in the coordinator commands: use $HOME/go/bin/ax, NOT
$HOME/.local/ax-v0.3.1/ax (the latter hits the AX-lane dispatch blocker recorded in the
unseen spec tasks.md). README.md + benchmarks/unseen/README.md.

The harvester cloned --filter=blob:none --no-checkout, then blame/log/diff
triggered the promisor to fetch each needed blob ON DEMAND -- hundreds of
round-trips per repo, the dominant cost that made the draw unable to
converge. The blobless clone was a premature optimization that backfired.
Drop --filter=blob:none from the clone and the two commit fetches. A
full-objects --no-checkout clone brings the whole commit graph AND every
blob in one pack, so blame/log/diff read locally; --no-checkout still
skips the working tree so disk stays bounded (plus the existing 500 MiB
clone_size_cap and the disk guard). With no promisor remote, a genuinely
missing object now errors loudly instead of silently round-tripping --
the instrument guarantee that the bulk fetch was complete.
Extraction semantics are unchanged (same SZZ introducing-commit positive,
same stratified ordinary negatives, byte-identical entries); only the
object-transfer strategy changes. Test inverted to assert no blob:none
filter on the clone; README updated. 145 unseen tests pass, ruff clean.

gVisor replays exhausted the hook's 30 s deadline in the snapshot step on a
1,725-file repository; cluster replays now use 30 s x a measured slowdown
factor, verified on a native sample. The engine runner deletes each pin's fetched
source (1.8 GB had accumulated), caps the cache at 500 MB and refuses below
1.5 GB free. Proof 4.4: two engine pins via the generic dispatcher match the VM
baseline exactly. Implemented with Codex.

Implemented with Codex; task 1.5 run by the coordinator against the real
sources (S3 memory read-only).
