Two independent costs in the background tick, both pure waste.
`list_directory` was called four times per tick -- once by the log pull and
once by each of the three bank syncs. It is the single most expensive call
in a tick at ~445ms mirrored (the GitHub half alone is ~360ms), so that was
~1.3s spent asking the same question four times. It is now listed once in
`run_sync` and passed down.
The curated-bank loop was worse: 17s and 62 requests to fetch *zero* useful
bytes. Firebase returns None for every peer's `food_bank_manual.json`, so
`MirrorSyncClient.get_file_text` treated each miss as "this device has not
migrated yet" and fell through to GitHub, which answers `{}` after ~320ms.
`_primary_only_text` skips that per-peer fallthrough for this one artifact.
Checked before narrowing rather than assumed, because CLAUDE.md requires
both halves of the food bank to sync: reading every peer's curated bank
straight off the mirror found 23 absent, 2 empty, and zero non-empty. No
curated food exists on the mirror alone. The probe is written into the
docstring so it can be re-run before anyone widens this again.
Measured end to end: manual-bank loop 17.0s -> 3.4s, full tick ~27s -> 15.2s,
log/bank/peer state unchanged (441 entries, 117 foods, 22 peers).
`_pull_remote_logs` now returns the revisions it saw instead of mutating a
caller-supplied dict, which keeps it under the argument limit and makes the
data flow visible at the call site.
Deliberately NOT done: revision-skipping the derived food bank. `run_sync`
rebuilds that bank from the merged log immediately before syncing it, so
unlike the log the peer records are not durably held locally -- skipping a
peer would drop its counts from the pushed bank and oscillate under
max-count-wins. Verified empirically: the on-disk bank and a pure log-derived
rebuild are identical (117 foods, 0 differing counts), and the 2 foods peers
know that the local bank lacks are discarded by the existing `if name in
local` filter anyway. The loop is off every interactive path now, so the
remaining cost is background-only.
