Moves the 'Dev Notes' sections from the lore-engine-merge PRD stories
(S2-phase-1-substrate-merge.md, S3-phase-2-ontology-time-planes.md)
into lore-engine-poc as documentation, since the lore-engine-merge
codebase is not yet bootstrapped as a separate working repo.
These notes document decisions made during the planned worker migration
from GraphMCP into the lore-engine stack:
- port remap 8765 → 8766 (damascus stack conflict)
- nsc plugin as single-file to match existing plugin convention
- discord-connector disabled via env var (per PRD ambiguity)
- multi-world ontology migration with defensive cleanup
When the lore-engine-merge codebase is bootstrapped, these notes can
be moved into docs/decisions/ there.
