}

Per-layer tallies for a walk, index build, and content pass.

Fields

dir_opens: u64

Logical directory-open operations.

dir_enumeration_calls: u64

Enumeration syscalls in complete successful macOS bulk listings, including the empty terminator.

One successful directory is typically two calls (one data, one EOF), the same multiplicity the Linux portable path pays in getdents64. The portable read_dir path leaves this at 0 because the standard library hides that split. Abandoned bulk attempts before portable fallback are not counted. A later Linux or openat campaign can compare this to dir_opens without another sample.

dir_entries: u64

Directory entries yielded by enumeration.

stats: u64

Logical metadata-stat operations.

file_opens: u64

File-open operations performed by content analysis.

file_reads: u64

File read calls performed by content analysis.

bytes_read: u64

Bytes read from files by content analysis.

allocs: u64

Allocation requests observed by the installed counting allocator.

reallocs: u64

Reallocation requests observed by the installed counting allocator.

frees: u64

Deallocations observed by the installed counting allocator.

bytes_allocated: u64

Bytes requested by allocations and allocation growth.

upserts: u64

Index upserts applied.

parent_resolutions: u64

Parent-path resolutions performed for index updates.

parent_memo_hits: u64

Parent resolutions served by the adjacent-parent memo.

rollup_merges: u64

Roll-up merge operations.

control_reads: u64

Control files read from the filesystem.

control_refused: u64

Control sources a control table refused for one of its limits.

Counted where the table decides, so a re-read of a file it has already refused is not: that batch cannot change the table and is never projected. A warm revalidate of a refused tree therefore reports its reads against no refusals, which is the projection being skipped rather than a refusal being lifted.

control_sources_shared: u64

Control sources that joined a retained identical content instead of parsing again.

entries_allocated: u64

Index entries allocated.

baseline_batches: u64

Successful detached baseline batches arbitrated by the index.

baseline_accepted_ops: u64

Operations accepted from successful detached baseline batches.

opened_batches: u64

Successful opened-root batches arbitrated by the index.

opened_accepted_ops: u64

Operations accepted from successful opened-root batches.

public_batches: u64

Successful arbitrary public batches arbitrated by the index.

public_accepted_ops: u64

Operations accepted from successful arbitrary public batches.

ancestry_overlay_inserts: u64

Path-keyed structural-overlay inserts during ancestry preflight.

ancestry_path_comparisons: u64

Same-parent path comparisons during ancestry preflight.

ancestry_parent_proofs: u64

Parent chains proved during ancestry preflight, including memo hits.

scanner_prepare_us: u64

Wall microseconds spent preparing trusted scanner batches.

scanner_control_projection_us: u64

Wall microseconds spent projecting controls for trusted scanner batches.

scanner_reduce_us: u64

Wall microseconds spent reducing prepared scanner batches into the index.

content_sidecar_read_us: u64

Wall microseconds spent reading the content sidecar image.

content_sidecar_parse_us: u64

Wall microseconds spent on sidecar integrity and record decode.

content_sidecar_candidates_us: u64

Wall microseconds spent building the live candidate map for a sidecar restore.

content_sidecar_apply_us: u64

Wall microseconds spent applying restored records and rebuilding content roll-ups.

detached_builds: u64

Detached cold scans that selected the directory-group builder.

detached_entries: u64

Entries consumed by that builder.

detached_walk_us: u64

Wall microseconds spent walking while the builder consumed directory groups.

detached_finish_us: u64

Wall microseconds spent in the final directories-only roll-up pass.

effect_paths: u64

Owned paths retained in exact effective changes.

effect_path_bytes: u64

Native encoded bytes retained by exact effective-change paths.

impact_candidates: u64

Change and state paths considered for bounded impact derivation.

impact_ancestor_visits: u64

Path ancestors visited while deriving bounded impact.

impact_retained_dirty_paths: u64

Dirty paths retained in completed bounded impacts.

impact_all_dirty: u64

Impact derivations that crossed the dirty-path bound.

journal_retained_commits: u64

Exact commits retained in the bounded journal.

journal_cloned_commits: u64

Exact commits cloned for attempted journal retention.

journal_oversized_commits: u64

Exact commits rejected because one commit exceeded journal capacity.

journal_dropped_commits: u64

Older exact commits dropped to admit a new retained commit.

adaptive_calibration_chunks: u64

Chunk releases folded into an automatic scan’s worker-scaling calibration.

adaptive_calibration_entries: u64

Entries folded into that calibration before it reached a decision.

adaptive_calibration_work_us: u64

Worker time, in microseconds, folded into that calibration.

Microseconds rather than nanoseconds because the decision threshold is expressed per entry in microseconds, and a nanosecond total over a multi-million-entry walk is large enough to make the row hard to read.

adaptive_scale_ups: u64

Reserve-pool expansions an automatic scan actually performed.

adaptive_policy_undecided: u64

Walks that ended while their scaling calibration was still undecided.

A walk shorter than the calibration window never observes enough entries to decide, so its worker policy is unobservable rather than merely unchanged. That is the distinction crate::scan fails closed on, and it must not read as a decision to hold.
