Session:17:29 (testaruda — ylyl root-cause + fix, ycg8/u1bv P3s, v0.5.1 release)

• Renew via turu recall (branch:main): claimed P3 testaruda-ylyl (julia runner exit 101, cold stores ingest 0)
• Root-caused empirically on XAct.jl: run-args emits julia --project=. -e 'using Test; include(...)' but [extras]/[targets.test] deps (Aqua/JET) are NOT in the project Manifest — Pkg.instantiate() provably does not install them (fresh resolve, grep Manifest = 0). Runner dies at using with julia's own remediation line, which the engine swallowed
• Extra finding: emitted ReTestItems.runtests(files=[...]) rejected by current ReTestItems (positional filters + name=/tags= kwargs); REPLy.jl hang is repo-side deps/build.jl scratch resolution
• Shipped PR #52 (ylyl): engine surfaces last-5 stderr lines of a failed runner after ingest (TIA-CI-008 order unchanged); 3 unit tests + live XAct verification; merged green, ylyl closed. Adapter-side gap filed: testaruda-ymzg (P2) + upstream sashakile/Testimonial.jl#1
• Closed both P3s in PR #53 (merged green): ycg8 — calibration ramp section in getting-started.md (init→exec→exec, SAFE-007/TIA-SAFE-002, measured ramp table dont 5/950 genesis 6/502 espectacular 17/401 vampiro 91/856) + regenerated stale-since-v0.3.0 docs/cli.md (fixes pre-existing doc-cli-check failure on main); u1bv — characterization tests pin cargo filter contract: substring filters kept, --exact rejected (would select 0 tests for short node_id names), prefix collisions over-run (recall-safe), stale names exit 0/0-run
• Prod-readiness verdict for user: Rust+Python effectively prod-ready on happy path; remaining gaps operator-facing (docs — now done) or edge-contract (now pinned)
• Released v0.5.1 (PR #54 merged, tag pushed): 12 fix PRs since 0.5.0 — cold-start loop fixes (python ingest deadlock 1m3i/00p9/l0ts, Rust inline self-edges khn7, hidden-dir n338/zlyk, polyglot kkno, venv n3wn, a6gw, ylyl diagnosis). GH release + crates.io 0.5.1 live; build matrix green
• Homebrew tap/scoop publish failed on TAP_GITHUB_TOKEN auth (known ehse blocker) — non-blocking; backfill possible without re-tag via update-homebrew.py + update-scoop.py against v0.5.1 checksums once token is set
• Next (user action): set TAP_GITHUB_TOKEN secret (PAT contents:write on homebrew-charly + scoop-charly) — backfills 0.4.0→0.5.1 on tap/scoop; also espectacular v0.7.0/v0.8.0 backfill pending same token. Next dev: ymzg (P2 julia adapter test-env), i5oe/n0hc (P3), 5q1/cwu (P4 epics)
