v1.34.0

"Elite" — feature parity + a code-execution token lever + provable savings. First
capability-bearing release since v1.29; v1.30–v1.33 were stabilization. Three tracks
plus release-hygiene automation.

Added

• Code-execution mode — ashlr__pipe (flag-gated ASHLR_PIPE_ENABLE=1): run a short
  sandboxed expression that calls other ashlr tools (ctx.{grep,read,bash,ls,glob}),
  filters/transforms results, and returns ONLY the distilled value — intermediate tool
  output never enters context. AsyncFunction isolation (no closure/module scope),
  deny-list, ≤2000-char exprs, 10s/30s timeout, 64KB intermediate + max_output_bytes
  caps, and single-aggregate savings accounting via a _noAccounting suppress flag.
• Three new hook events: PreCompact (inject a ≤600-byte genome-ToC + session-state
  "survival kit" right before auto-compaction), SubagentStop (roll a finished subagent's
  savings into the session log + fire genome consolidation), Stop (deterministic,
  idempotent session-accounting finalization complementing SessionEnd).
• Four model-invoked Skills + SessionStart toggles: ashlr-search, ashlr-lean-tools,
  ashlr-genome-author, ashlr-cost-refactor.
• Output style ashlr-efficient — structural density (inline code, tables, inverted
  pyramid); composable with ashlr-brief.
• Measured-savings mode — servers/_token-measure.ts derives true cl100k token counts
  from the Anthropic API (max_tokens:1, fire-and-forget, SHA-256 LRU cache). Savings now
  label (API-measured) vs (est.) in /ashlr-savings, the dashboard, status line, and
  the SVG badge once ≥10 measured calls accrue.
• Reproducible benchmark — run-benchmark.ts gains bootstrap confidence intervals,
  --validate-tokenizer (heuristic-error vs API), and a --compare A/B table.
• Honest genome retrieval — grep header shows embedMode (cold/warm/hot/…), a
  one-time cold-corpus nudge, TF-IDF re-ranking + camel/snake trigram expansion in
  _genome-search.ts (no-regression on a cold corpus), and an Ollama auto-detect hint in
  /ashlr-doctor.
• Release-hygiene automation — scripts/bump-version.ts (single source of truth across
  package.json + plugin.json + marketplace.json) and scripts/check-version-sync.ts (CI
  gate). Wired into ci.yml, release.yml, and publish.sh.

Fixed

• Version drift — manifests were stuck at 1.29.0 while tags reached 1.33.0; now synced
  to 1.34.0 and enforced by CI so it can't recur.
• Stale plugin-metadata test — pinned to "31 slash commands" since PR #77; aligned to
  the canonical 33.

Internal

• _stats.ts schema extended additively (optional tokensSavedMeasured/measuredCalls,
  no schema-version bump, back-compatible).
