Distill the cross-cutting adapter-contract constraints from the four engine
deep dives (wiki-engines landscape, XWiki, TWiki, Foswiki) into five concrete
design tasks, complementing the federation tasks (T1-T10):
- T11 adapter contract: capability model & versioned interface (Foswiki::Store
prior art; write-granularity as a capability dimension)
- T12 page model: structured/typed payload representation (XObjects, %META%,
multi-record, bodiless pages)
- T13 history portability: supplement (DB-internal) vs import (open file history)
- T14 adapter binding: attach path, engine-hosted vs external, backend-swap
- T15 syntax translation & content fidelity (non-Markdown round-trip)
Adds an adapter-contract decision-topics table, cross-links T10<->T11 on the
shared capability vocabulary, and updates context/acceptance/task-order. Tasks
registered in the state hub (workstream 2af4c46d).
