+## Advisory Handling (must do for every new advisory)
+- **Trigger:** any new/updated file in `docs/product-advisories/` (current or archived) automatically requires updates below—no chat approval.
+- **Docs:** add/update a high-level page in `docs/` (vision/key-features/market) and a detailed page in the closest area (`docs/reachability/*`, `docs/market/*`, `docs/benchmarks/*`, `docs/modules/<module>/*`, etc.). Inline only short snippets; place runnable/long code in `docs/benchmarks/**` or `tests/**` (deterministic, offline-friendly) and link.
+- **Sprints:** add Delivery Tracker rows in the relevant `SPRINT_*.md`, include doc paths, owners, deps; add an Execution Log line and risks/interlocks (schema/feed freeze, transparency caps) when needed.
+- **De-dup:** check `docs/product-advisories/archived/`; mark “supersedes/extends <advisory>` if overlapping to avoid duplicate tasks.
+- **Defaults:** hybrid reachability posture (graph DSSE required; edge-bundle optional), deterministic/frozen feeds, offline-ready benches.
+- **Do not defer:** execute steps immediately, then report.

 ## Cross-Module Coordination
 - Respect each module’s AGENTS.md when touching module-specific sprint entries; do not change module instructions from here.
 - If a required module AGENTS.md is missing/outdated, mark the related task BLOCKED in that module’s sprint and note it in Decisions & Risks here.
