What changed

Corrects skill instruction links and capability examples, and aligns onboarding trees with all five element layers and root-level views. Documents supported legacy forms and the retired issues notation.

Extends the existing shared documentation checks to skill protocols, prompts, templates and fixture documentation. Links resolve in their source, installed-guide or fixture namespace; snapshot examples validate their source IDs. Regression fixtures exercise valid instructions and reject broken links, invalid IDs and incomplete trees. No new published files are added.

How it is verified

• node scripts/check-notations.mjs: passes for 21 view notations, with four existing advisory warnings.
• node --test scripts/check-notations.test.mjs scripts/release-obligations.test.mjs: 120 pass, zero failures or skips.
• Skill cheat-sheet and workflow-script checks pass.
• Deterministic onboard, ingest, reg-intel and knowledge-store integrity suites pass, including supersession and migration checks.
• Local environment: Node 22.23.2, Python 3.12.3, PyYAML 6.0.1; hosted workflows declare Node 20 and Python 3.12.
• LLM drive jobs were not executed. Source and temporary installation checks do not claim publication or adopter installation.

Checklist

• Based on main, one concern per PR.
• Commit carries DCO sign-off.
• Changed files and public metadata reviewed for disclosure hygiene.

Independent review of exact head dde7e0c: diff and documentation-path semantics are clean. Re-ran the 120 Node checks, notation lint, onboard/ingest/reg-intel/knowledge-store integrity suites, cheat-sheet conformance, and diff hygiene successfully.
