 - `LLM.md` as a compact agent-readable guide to the repo.
 - README front-door cleanup, including the routing table and compatibility/control matrix.
 - A clearer repo-specific `AGENTS.md`.
+- A portable output contract inside every installed skill.
+- Validation that rejects skill links escaping the installed skill folder.
 
 ### Changed
 
 - README sections were consolidated for faster scanning.
+- The quickstart now asks users to choose one install target instead of running both installers.
+- Downstream skills now accept fact ledgers or conversation-state records explicitly and preserve their source classifications.
+- Optional template references no longer use repository-relative paths that break after installation.
 
-### Notes
+### Fixed
 
-- This branch is documentation and productization only; skill behavior is unchanged.
+- Installed skills no longer depend on `../../references` or `../../templates` paths that are absent from the installed layout.
+- Assumptions, open questions, proposed actions, and stakeholder positions may not be promoted into facts, decisions, commitments, owners, or deadlines without new source support.

 The skills provide reusable instruction contracts and examples. They help an assistant preserve uncertainty, identify asks, surface owners, draft replies, and avoid unsafe action.
 
+Each installed `SKILL.md` is self-contained: the critical uncertainty, handoff, and mutation rules travel with the skill folder rather than depending on repository-only links.

 Slack threads, email chains, doc comments, tickets, and transcripts can all carry the same source state as a live meeting. Treat them as async collaboration: extract facts first, then move to the next clear action.
