Phase B step 1 of the Tailscale-SSH route to mRiver. Splits the existing
local-tmux PoC into a Paliadin interface with two implementations; the
remote-SSH backend lands in a follow-up commit (paliadin_remote.go).
Surface:
- Paliadin interface — RunTurn, ResetSession, ListRecentTurns, Stats,
IsOwner. The handler at internal/handlers/paliadin.go now talks to
this instead of the concrete struct.
- paliadinDB — embedded base type carrying the audit-table I/O
(insertTurnRow, completeTurn, markTurnError, markTurnAbandonedOrError)
plus the read-side queries (IsOwner, ListRecentTurns, Stats). Both
Local and Remote impls inherit these by embedding paliadinDB so the
remote path doesn't have to duplicate any DB code.
- LocalPaliadinService — the renamed PoC backend. Identical behaviour
to the previous PaliadinService; only the type name and method
receivers change. Method receivers split: tmux-specific operations
(RunTurn, ResetSession, ensurePane, sendToPane, pollForResponse, etc.)
stay on *LocalPaliadinService; DB-only operations promote to
*paliadinDB.
Wiring:
- internal/handlers/handlers.go — Paliadin field becomes the interface
type; Register() unchanged.
- cmd/server/main.go — calls NewLocalPaliadinService instead of
NewPaliadinService. The remote-vs-local switch on PALIADIN_REMOTE_HOST
lands in B5.
Tests in paliadin_test.go all green — they test package-level functions
(splitTrailer, countChips, approxTokenCount, sanitiseForTmux,
PaliadinOwnerEmail) and don't touch the renamed struct. No behaviour
change on the local-tmux path.
