docs(#1130): chat-to-AIRC migration proof gates#1141
Merged
Conversation
Per Joel's request on the card: codify what must be PROVEN — not just
compiled — at each stage of moving Continuum's chat path from the ORM-
backed chat_messages collection onto AIRC as the primary transport.
What this is: a planning document, no code change. Specifies the
inventory of every chat_messages call site, the four migration stages
(ORM only → dual-write → AIRC primary → ORM removed), and the explicit
proof gates per transition (compile, functional, mirror-lag SLO, failure
modes, smoke).
Three pieces worth flagging:
1. Inventory commands are runnable: a future migration PR's body must
include the inventory diff, and any new entry not listed here blocks
the merge. Forces the inventory to stay current.
2. Per-call-site cutover table covers every consumer in the inventory
(chat/{send,export,poll,analyze}, DataLoaders, PersonaUser, ai/
{thoughtstream,report}, DataReadServerCommand chat-access-control,
EventConstants registry). Each row gets a status field; PRs updating
any row update this file in the same commit.
3. Open decisions section lists the 4 questions that block stage 0 → 1:
dual-write atomicity, message-ID canonical, history backfill, and
tombstone semantics. Each comes with a recommendation; the document
doesn't pretend they're settled.
Adjacent docs (referenced, not duplicated):
- docs/grid/AIRC-CONTINUUM-BRIDGE.md — wire format, transport
- docs/grid/GRID-ARCHITECTURE.md — multi-machine semantics (out of
scope for v1 single-machine cutover)
- continuum#1129 / #1133 / #1134 — engram + admission gate (orthogonal,
can proceed in parallel)
