swath 0.2.1

swath 0.2.1

User-facing changes

• swath --version now identifies the build, source revision, Java runtime, and Varve;
  root help carries the same unobtrusive Varve attribution.
• Dataset startup and resume now refuse pre-existing symlinks in managed output,
  checkpoint, marker, and sorted-staging paths before swath can truncate or overwrite an
  external target. Existing valid datasets need no migration.
• Release downloads and images are now bound to the exact tagged source. The publication
  path runs fresh fast, integration, deep, kill-9 resume, licence, and instrumentation
  gates; stages an exact asset set; and verifies checksums, signatures, attestations, and
  published assets before making the GitHub release public.
• Installation and packaging documentation now describe the released artifacts and
  container images directly instead of the retired pre-release workflow.

Evidence

• Ten adversarial CLI tests cover dataset-root, checkpoint, SQLite sidecar, marker-temp,
  markerless part-file, explicit-restore, and deterministic sort-segment symlinks while
  asserting that external targets remain unchanged.
• The merged change passed the full local ./gradlew build gate, independent CodeRabbit
  and Opus reviews, and main CI's fast, integration, deep, Docker, and CodeQL checks.
• The release workflow independently rebuilds and retests the immutable tag before any
  publication step, then self-verifies the resulting downloads and container digest.

Limits and known issues

• Filesystem protection covers links that exist when a command validates its dataset; it
  does not claim to defend a writable output directory against hostile concurrent
  mutation during the run.
• This is the first release through the newly hardened publication workflow.

What's Changed

swath 0.2.0

What's Changed

• just release: emit the post-release -SNAPSHOT bump commit too by @sagiba in #66
• Make the sim's position sensor swappable, and race candidate cures over captured listings by @sagiba in #67
• Put the remaining-work estimate behind a seam, and port the race's promoted sensor by @sagiba in #68
• Make the simulator honest about serial tails: consume the engine gate chain, fix the probe:page ratio, add per-decision gate visibility by @sagiba in #69
• Cure the wide-flat serial tail: a raceable tail_floor mode for the owner-split child-tail floor by @sagiba in #70
• Turn the sensing/tail-floor pair on by default by @sagiba in #79
• replay-server: serve open-upper-bound delimiter rollups through the native skip-scan by @sagiba in #80

• Count the open-frontier skip and attribute its drained keys by @sagiba in #82
• chore: close the serial-tail review punch list, and stop the toggles line calling the documented rollback unsupported by @sagiba in #86
• engine: close the top scope so its rightmost mass stops being unsplittable (porotomo 95% serial -> 0%, wall -36%) by @sagiba in #88
• sim: condense production comments to current contracts, reconcile the simulator docs by @sagiba in #89

• Deflake the FILE-publication staging test and cut the fast tier from 2m06s to 1m17s by @sagiba in #10
• Get the deep tier green: re-baseline the probe-timeout fixtures against the strict steal bound by @sagiba in #11
• Spend the seed budget mass-aware: level-ordered frontier and sampled-sibling prior by @sagiba in #17
• Separate listing-decision logic from execution behind a policy seam by @sagiba in #32

• Add an sdk_unmarshal call-class latency phase for the SDK's own response handling by @sagiba in #50
• Span the Parquet writer pool's encode/write work by @sagiba in #51
