Why: Allow consumers to download an immutable module revision without nested source checkouts or local path replacements.
Evidence: SELF package tests and the prior canonical-path rejection are recorded in the Dev dependency-workspace task card; remote consumption is replayed against the committed candidate.
Impact: Change the module identity and its Go imports while preserving API behavior. Existing historical submodule revisions remain buildable.

Why: GET /api/commands/audit leaked every tenant's audit rows (command ids, entrances, conversation ids, param digests) to any authenticated user; owner was never recorded nor filtered.
Evidence: Red run at a7cc69b FAIL (alice sees bob's row); after fix go test ./... 32/32 packages ok, including TestCommandAuditOwnerScoping and the v18 backfill test (rows recorded on the task card).
Impact: v18 migration adds command_audit.owner with actor-based backfill (empty-actor rows stay invisible via API, kept in-table); AppendAudit/ListAudits gain owner params; cmdbus port and fakes updated; handler passes authenticated owner. No public extension surface change.
Refs: Task card R1; U0 proposal section 5 C7 finding.
Why: Downstream products must extend the base through a public package and host API instead of editing internal code.
Evidence: go test ./... passed, including plugin v2 assets, sidecar startup, migration v13, pending confirms, HITL timeout, hash embedder, command pairs, and the extension surface snapshot.
Impact: apiVersion 2.0-experimental rejects empty network allowlists for declarative HTTP. Hash embeddings stay opt-in via models.embedding.provider=hash. Plugin secrets resolve per owner at execution time.
