With use-memfd + memfile-diff-dedup enabled, dedup.deduped_pages reports large negative values (≈ −68k observed on staging). runDedup builds the diff metadata with Empty: plan.pageEmpty (same bitmap) and then merges the block-granular inputEmpty ranges into it before recordDedupAttrs reads the plan, so dedup.empty_pages counts whole-VM empties instead of the scan's content-detected zeros and deduped = total - unique - empty goes negative, making dedup.ratio unusable for tuning the new dedup budget.

Clone the bitmap for the metadata merge; the plan keeps the scan-only set.

fix(orchestrator): keep dedup empty-pages telemetry scan-only
bfa319b 
meta.Empty aliased plan.pageEmpty, so merging the block-granular
inputEmpty bitmap before recordDedupAttrs inflated dedup.empty_pages to
whole-VM scale and drove dedup.deduped_pages negative. Clone the bitmap
for the metadata merge so the span attributes report content-detected
zeros only.

PR Summary

Low Risk
Observability-only change to metric attributes; diff metadata still merges inputEmpty as before.

Overview
Fixes dedup OpenTelemetry metrics on the memfd dedup path where inputEmpty (whole-VM empty blocks) was merged into plan.pageEmpty before recordDedupAttrs ran, inflating dedup.empty_pages and driving dedup.deduped_pages negative and dedup.ratio unusable.

recordDedupAttrs now takes an explicit scan-only empty page count; the memfd path snapshots that count before merging inputEmpty into the plan bitmap for diff header metadata (no bitmap clone). dedup.header_empty_pages records the full header empty set separately. The cache Dedup path passes the plan’s scan-only cardinality unchanged.

Code Review

This pull request clones the plan.pageEmpty object before merging inputEmpty to ensure it remains scan-only and correctly reports content-detected zeros. There are no review comments, and I have no additional feedback to provide.

d94bfd0 
…v#2991)

With `use-memfd` + `memfile-diff-dedup` enabled, `dedup.deduped_pages`
reports large negative values (≈ −68k observed on staging). `runDedup`
builds the diff metadata with `Empty: plan.pageEmpty` (same bitmap) and
then merges the block-granular `inputEmpty` ranges into it before
`recordDedupAttrs` reads the plan, so `dedup.empty_pages` counts
whole-VM empties instead of the scan's content-detected zeros and
`deduped = total - unique - empty` goes negative, making `dedup.ratio`
unusable for tuning the new dedup budget.

Clone the bitmap for the metadata merge; the plan keeps the scan-only
set.
