Candidate: d41a618 (main after #9: build-time commit in bundle provenance,
golden-path CI on x86_64 Linux, arm64 Linux and arm64 macOS).
Frozen release binary (cargo build --locked --release, M1 Pro, Rust 1.98.1):
b2f15f2e715c7d45213bebddf2a44c9b8ac1dfa8b3acd942eeb7c1f30fda3d89

Candidate battery (docs/audits/1.0-current-validation.md), all passed:
- scripts/ci_local.sh full; Rust 1.92.0 headless all-target tests
- K-parity: Q4_K_M 7/7, Q6_K 7/7 (ARM tier)
- Golden ladder (Gate C): 6/6 rungs, top-1 2/2 each; metrics identical to
  the 2026-09-28 candidate
- Golden path: passed, reproduction exact-semantic
- Six-site captures, interventions, scale, observer: passed
- Python binding rebuilt from source; 133 tests passed, 1 skipped
- Gate H vs the adapted v0.4 baseline: Q4_K_M and Q6_K, 24/24 cells within
  the 3% throughput and RSS limits

Not a release: v1.0.0 still waits on the external gates (clean-machine
install, independent external user, desktop GUI acceptance).
