composeThreeWay

Kind: Function

Source: atloria-monorepo/apps/api/src/change-request/merge-compose.ts

Compose the auto-merged document from aligned three-way sections (S2.3 merge).

PURE — no I/O. The caller (CrWorker's merge gate) has already classified every section via DiffService.threeWaySections and verified NONE are 'conflict'; this walks the aligned slots in order and takes:

• 'keep-mine' → mine (main moved this section; the proposal left it alone)
• 'take-theirs' → theirs (the proposal changed this section; main left it alone)
• 'unchanged' → mine (mine === theirs by definition — either side works)

A section DELETED on the winning side compares as '' and is dropped from the composition (this also covers the deleted-on-both-sides slots threeWaySections appends as 'unchanged'). Section texts carry no trailing newline (they are joined line runs), so the composition re-joins with '\n' and ends with a single trailing newline — matching the normalised form every committed page already has.
