Task 14. A GATE document, not an implementation plan - the plan explicitly wants
Phase 2 planned against post-Phase-1 reality, which means after this record
exists rather than from the original design alone.
Records what Phase 1 actually established (ordering constraints, where
registration lives and why, the fail-closed interceptor, the silent meter
allowlist), what must be ported before anything is deleted (both bespoke
replicator test files, treated as specifications, plus the accepted N5
bounded-duplicate race), and why Phase 2 is a harder risk class than Phase 1:
it REPLACES a working mechanism rather than adding one where none existed,
sf_messages has external side effects, config tables drive deployment, there is
no dual-mechanism period, and the migration is real this time rather than the
usual no-op.
The most important line is an open question, not an answer: choosing
MaxOplogRows / MaxOplogAge / snapshot-resync thresholds for sf_messages write
rates needs a Phase-1 rig SOAK that has not been run. The live gate proved
correctness, not steady-state behaviour over time. Phase 2 should not be planned
without it.
tasks.json finalized: all 15 tasks completed, every deviation from the plan
recorded with its reason.
