Conflicts: CHANGELOG (additive), test/gstack-skill-start.test.ts (keep expectAbsent import), skill-md-size-allowlist (ours, re-pinned), generated SKILL.md (regenerated). Main's plan-eng-review pointer (+14 in SKILL.md under the hoist) is offset in the same commit: /autoplan's skip list and the INVOKE_SKILL defaults skip 'Shared preamble (load first)' and drop the two shared-only headings, so 30 pins go down and none is raised. Ship goldens regenerated. The agents-digest Boil the Ocean bullet takes the complete-coverage wording (#3451 unblocked it).

Every tier 2+ SKILL.md inlined the same ~23 KB preamble. It now renders once
per host into sections/preamble.md beside each tier 2+ SKILL.md; the SKILL.md
keeps a pointer that asks for the Read only when the file's id is not already
in context. Only sections byte-identical to the shared render move, so every
skill keeps exactly its pre-hoist paragraphs (verified across all 41 skills).
Parity caps for ten skills raised to their measured unions (owner-approved,
Garry 2026-10-25: "do it"); 63 size pins lowered and 26 deleted.
