Builds on PR-1, PR-2, PR-3, PR-4 (all merged). Adds the agent-facing
v2 surface for the memory plugin contract.
What ships (all in handlers/mcp_tools_memory_v2.go, no edits to
the legacy commit_memory / recall_memory paths):
commit_memory_v2 — write to a namespace; default workspace:self
search_memory — search across namespaces; default = all readable
commit_summary — kind=summary, 30-day default TTL, runtime-overridable
list_writable_namespaces — discover what you can write to
list_readable_namespaces — discover what you can read from
forget_memory — delete by id, only in namespaces you can write to
Workspace-server is the security perimeter — every layer the plugin
mustn't be trusted with runs here:
* SAFE-T1201 redactSecrets BEFORE every plugin write
* Server-side ACL re-validation: CanWrite + IntersectReadable run
on EVERY request, never trusting client-supplied namespaces (a
canvas re-parent between list_writable and commit would otherwise
let a stale namespace slip through)
* org:* writes audited to activity_logs (SHA256, not plaintext) —
matches memories.go:201-221 so the schema stays uniform
* Audit failure does NOT block the write (logged + continue) —
failing closed would deny org-scope writes whenever activity_logs
is unhappy
* org:* memories get the [MEMORY id=... scope=ORG ns=...]: prefix
on read — preserves the prompt-injection mitigation from
memories.go:455-461
Coexistence design: legacy commit_memory + recall_memory still wired
to their old code paths in mcp_tools.go. PR-6 will alias them to
delegate to these v2 implementations. PR-9 (60 days post-cutover)
removes the legacy entries.
Wiring:
* MCPHandler gains an memv2 field (nil-safe; tools return a clear
error when MEMORY_PLUGIN_URL is unset rather than crashing)
* WithMemoryV2(plugin, resolver) is the production wiring API
main.go calls at boot
* withMemoryV2APIs(plugin, resolver) is the test-injectable variant
against the memoryPluginAPI / namespaceResolverAPI interfaces
Coverage: 100.0% on every new function in mcp_tools_memory_v2.go.
Edge cases pinned:
* empty/whitespace content → reject before plugin
* plugin unconfigured → clear error, no crash
* ACL violation → clear error
* resolver error → wrapped error
* plugin error → wrapped error
* malformed expires_at → silently ignored (no exception)
* org write audit failure → logged, write proceeds
* search namespace intersection drops foreign entries
* search with all-foreign namespaces → empty result, plugin not called
* search org memories get delimiter wrap, workspace memories do not
* forget with explicit + default namespace
* forget cross-scope rejected
* pickStr / pickStringSlice handle missing keys, wrong types, mixed slices
* wrapOrgDelimiter format is exact-match
* dispatch wires all 6 tools (no "unknown tool" error)
