v1.5.0 — atomic ingestion, crash-recovery groundwork, first community PRs

The release where Bernstein stopped losing state on force-stop and the first wave of outside contributors landed.

What's new

• Atomic batch ticket ingestion. Tasks are claimed in groups; if the POST fails, no files move. Force-stop and partial-write races no longer leave a half-claimed backlog (#241-#244).
• Parallelised, isolated test suite. A per-file runner replaces the single-process invocation that was OOM-killing CI across 2000+ tests. The legacy pytest tests/ path stays available, but scripts/run_tests.py is the sane default.
• WAL groundwork for crash recovery. Idempotent task operations land first; the WAL writer that consumes them ships in v1.6.x. Restart-safety stops being aspirational.
• Path-traversal fix. lstrip('/') was stripping absolute paths in the file-write validator, opening the very class of vulnerability the validator existed to close. Closed; regression test in place.
• Budget enforcement under concurrency. A check-then-write race let two agents simultaneously cross a hard budget cap. Replaced with a CAS-style update; over-budget agents are now rejected deterministically.

Community contributions

Thanks to the contributors who shipped real surface area in this release:

• --dry-run for bernstein compose — @forfreedomforrich-eng (#274)
• bernstein config diff — @TheCodingDragon0 (#264)
• Glossary of Bernstein-specific terms — @TheCodingDragon0 (#252)
• Hardcoded-URL fix in triggers — @forfreedomforrich-eng (#568)
• Skill-publish validation workflow — @internet-dot (#581)

Why we built this

Force-stop was the most common operator complaint after v1.4: "I hit Ctrl+C and now my backlog is in three different states." Atomic ingestion and the WAL groundwork are the structural fix — not a layer of retries on top. Everything else here is the contributor surface that grew once people could actually clone the repo and run the test suite without needing 64 GB of RAM.
