063-node-binding-parity

Node binding parity: acquisition source, profiles and variants, store seam, capture, repeatability commands (amends 027, 029, 034, 036 and 044)

Lifecycle approvedImplementation completeVerification unknownQualification unknown

An amendment of approved spec 027, closing the Node exposure that specs 029, 034, 036 and 044 left out of scope (#56, with #62 and #73), for release 0.5.0. `@rustev/rustev` gains a host-implemented acquisition source for 036's `acquire` and `widen` steps; profile, variant and base-profile inputs on `compile`, with `profileCheck` and `planDiff`; a host `RuntimeStore` for 044's persistent tier, with a stated atomicity contract and invalidation; opt-in capture on `decide` that returns a replay bundle, because the evidence a host sink receives cannot replay a decision; and 029's repeatability commands with 061's host import, in process. Each uses 027's seam rules, the Rust API the CLI calls and the shared conformance suite; the WebAssembly package gains none. Ratified by the owner on 2026-11-03 (A-78).
