feat: Add comprehensive product advisories for improved scanner functionality

- Introduced a blueprint for explainable quiet alerts, detailing phases for SBOM, VEX readiness, and attestations.
- Developed a roadmap for deterministic diff-aware rescans, enhancing scanner speed and efficiency.
- Implemented a hash-based SBOM layer cache to optimize container scans by reusing previous results.
- Created a multi-runtime reachability corpus to validate function-level reachability across various programming languages.
- Proposed a stable SBOM model using SPDX 3.0.1 for persistence and CycloneDX 1.6 for interchange.
- Established a validation plan for quiet scans, focusing on provenance and CI integration.
- Documented guidelines for the Findings Ledger module, outlining roles, execution rules, and testing protocols.

+# Docs Guild Update — 2025-10-22
+
+**Subject:** Concelier Authority toggle rollout polish  
+**Audience:** Docs Guild, Concelier WebService Guild, Authority Core
+
+- Added a rollout phase table to `docs/10_CONCELIER_CLI_QUICKSTART.md`, clarifying how `authority.enabled` and `authority.allowAnonymousFallback` move from validation to enforced mode and highlighting the audit/metric signals to watch at each step.
+- Extended the Authority integration checklist in the same quickstart so operators tie CLI smoke tests to audit counters before flipping enforcement.
+- Refreshed `docs/modules/concelier/operations/authority-audit-runbook.md` with the latest date stamp, prerequisites, and pre-check guidance that reference the quickstart timeline; keeps change-request templates aligned.
+- Documented the new Go analyzer artefacts in `docs/24_OFFLINE_KIT.md` (manifest excerpt + tarball smoke test) so Ops can confirm the plug-in ships in the 2025‑10‑22 bundle before promoting it to mirrors.
+
+Next steps:
+- Concelier WebService owners to link this update in the next deployment bulletin once FEEDWEB-DOCS-01-001 clears review.
+- Docs Guild to verify the Offline Kit doc bundle picks up the quickstart/runbook changes after the nightly build.
