…n (P101) Add Phase 3A acquisition crate startup wiring to the serve command: - Layer 0: Zetesis (search/indexer) - Layer 1: Ergasia (download engine via SessionEngine adapter) - Layer 2: Syntaxis (download queue with event listener) - Layer 4: Syndesmos (external integrations with event handler) - Layer 4: Prostheke (subtitle service) Extend AppState with dyn-compatible trait handles for each subsystem. Add HostError variants for acquisition crate errors. Validate download_dir exists and is writable before acquisition startup. Graceful shutdown cancels subsystems in reverse layer order. Observations: - Episkope crate (Layer 3, monitoring) does not exist in workspace — skipped - librqbit DurationWithHumanReadable has private inner field — ETA dropped Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Summary
servestartup/shutdown with correct layer ordering (0→1→2→4)AppStatewithArc<dyn DynXxx>handles for each subsystem via new placeholder traits in parocheHostErrorvariants,validate_download_dir()hard check, and graceful reverse-order shutdownLayer ordering
Observations
DurationWithHumanReadablehas a private innerDurationfield — ETA computation dropped from progress adapter, returnsNone.StubImportServiceused for syntaxis import pipeline — real import wiring deferred to follow-up prompt.Blast radius
