From 5bfa4b1d803d93b25237dc81bf6ebb2f9489c9fb Mon Sep 17 00:00:00 2001 From: Hongming Wang Date: Mon, 4 May 2026 07:50:26 -0700 Subject: [PATCH 01/19] Memory v2 PR-5: 6 new MCP tools wired through the plugin MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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) --- workspace-server/internal/handlers/mcp.go | 92 ++ .../internal/handlers/mcp_tools_memory_v2.go | 380 ++++++++ .../handlers/mcp_tools_memory_v2_test.go | 888 ++++++++++++++++++ 3 files changed, 1360 insertions(+) create mode 100644 workspace-server/internal/handlers/mcp_tools_memory_v2.go create mode 100644 workspace-server/internal/handlers/mcp_tools_memory_v2_test.go diff --git a/workspace-server/internal/handlers/mcp.go b/workspace-server/internal/handlers/mcp.go index bc0b9668..9126955f 100644 --- a/workspace-server/internal/handlers/mcp.go +++ b/workspace-server/internal/handlers/mcp.go @@ -83,6 +83,12 @@ type mcpTool struct { type MCPHandler struct { database *sql.DB broadcaster *events.Broadcaster + + // memv2 is the v2 memory plugin wiring (RFC #2728). nil-safe: + // every v2 tool calls memoryV2Available() first and returns a + // clear error rather than crashing when the operator hasn't set + // MEMORY_PLUGIN_URL. + memv2 *memoryV2Deps } // NewMCPHandler wires the handler to db and broadcaster. @@ -217,6 +223,76 @@ var mcpAllTools = []mcpTool{ }, }, }, + + // ───────────────────────────────────────────────────────────────── + // v2 memory tools (RFC #2728).

Adds the bridge that lets legacy commit_memory / recall_memory tools route through the v2 plugin path when MEMORY_PLUGIN_URL is wired, otherwise fall through to the existing DB-backed code unchanged. What ships: * handlers/mcp_tools_memory_legacy_shim.go — translation helpers: scopeToWritableNamespace, scopeToReadableNamespaces, commitMemoryLegacyShim, recallMemoryLegacyShim, namespaceKindToLegacyScope * handlers/mcp_tools.go — toolCommitMemory + toolRecallMemory now delegate to the shim when memv2 is wired Translation: commit: LOCAL → workspace: TEAM → team: (resolver picks at runtime) empty → defaults to LOCAL (preserves legacy default) GLOBAL → still rejected at MCP bridge (C3 preserved) recall: LOCAL → search restricted to workspace: TEAM → workspace: + team: empty → all readable (matches v2 default behavior) GLOBAL → blocked at MCP bridge (C3 preserved) Response shapes are preserved exactly: commit: {"id":"...","scope":"LOCAL"|"TEAM"} — agents see no diff recall: [{"id":"...","content":"...","scope":"LOCAL"|...,"created_at":"..."}, ...] org-namespace memories get the same [MEMORY id=... scope=ORG ns=...] prefix as v2 search; legacy scope label comes back as "GLOBAL" Operational rollout: * Today: MEMORY_PLUGIN_URL unset on most operators → legacy DB path * After PR-7 backfill: operators set MEMORY_PLUGIN_URL → all writes flow through plugin transparently * After PR-8 cutover: dual-write removed, plugin is the only path * After PR-9 (~60 days later): legacy tool entries dropped entirely Coverage: 100% on every helper, 100% on recallMemoryLegacyShim, 94.7% on commitMemoryLegacyShim. The 1 uncovered line is a defensive guard against a v2-response-parse error that's unreachable when the v2 tool is operating correctly (it always returns valid JSON). Edge cases pinned: * scope translation for every legacy value + invalid scope * resolver error propagation * plugin error propagation * GLOBAL still blocked * default-scope fallback (LOCAL) * empty content rejected * No-op when v2 unwired (legacy SQL path exercised via sqlmock) * org-namespace memory wrap on recall + GLOBAL scope label round-trip * No-results returns "No memories found."

Operator runs this once at cutover to copy agent_memories rows into the v2 plugin's storage. Usage: memory-backfill -dry-run # count + diff, no writes memory-backfill -apply # actually copy memory-backfill -apply -limit=10000 # cap rows per run memory-backfill -apply -workspace= # one workspace only Required env: DATABASE_URL + MEMORY_PLUGIN_URL. Translation matches the PR-6 legacy shim: LOCAL → workspace: TEAM → team: (resolved via the same namespace.Resolver the runtime uses) GLOBAL → org: Idempotent: each row is keyed by its UUID; re-running the backfill does not duplicate writes (plugin handles deduplication). What ships: * cmd/memory-backfill/main.go: CLI entry, run() driver, backfill() workhorse, mapScopeToNamespace + namespaceKindFromString helpers * main_test.go: 100% on the functional logic (mapScopeToNamespace, namespaceKindFromString, backfill(), all CLI validation paths) Coverage: 80.2% of statements. The 19.8% gap is main()'s body (log.Fatalf — not unit-testable) and run()'s real-DB integration (sql.Open + db.PingContext + new client/resolver — requires a live postgres). Integration coverage for this path lives in PR-11 (E2E plugin-swap test). Edge cases pinned (in functional logic): * Every legacy scope → namespace mapping * Unknown scope → skip with diagnostic, increment skipped counter * Resolver error → propagate, abort run * No-matching-kind in writable list → skip with error message * Plugin UpsertNamespace error → increment errors, continue * Plugin CommitMemory error → increment errors, continue * Query error → propagate, abort * Scan error → increment errors, continue * Mid-iteration row error → propagate, abort * Workspace filter passes through to SQL WHERE clause * Dry-run mode never calls plugin * CLI: rejects both/neither modes, missing env vars, bad flags --- workspace-server/cmd/memory-backfill/main.go | 247 ++++++++++++ .../cmd/memory-backfill/main_test.go | 368 ++++++++++++++++++ 2 files changed, 615 insertions(+) create mode 100644 workspace-server/cmd/memory-backfill/main.go create mode 100644 workspace-server/cmd/memory-backfill/main_test.go diff --git a/workspace-server/cmd/memory-backfill/main.go b/workspace-server/cmd/memory-backfill/main.go new file mode 100644 index 00000000..96ef7d21 --- /dev/null +++ b/workspace-server/cmd/memory-backfill/main.go @@ -0,0 +1,247 @@ +// memory-backfill is a one-shot CLI that copies rows from the legacy +// agent_memories table into the v2 plugin via its HTTP API. +// Idempotent on re-run: each row is keyed by its UUID, and if the +// plugin sees a duplicate it returns 409 (or just no-ops, depending +// on plugin) — the backfill proceeds. +// +// Usage: +// memory-backfill -dry-run # count + diff +// memory-backfill -apply # actually copy +// memory-backfill -apply -limit=10000 # cap rows per run +// memory-backfill -apply -workspace= # one workspace only +// +// Required env: +// DATABASE_URL — workspace-server DB (read agent_memories) +// MEMORY_PLUGIN_URL — target plugin (write memory_records) +package main + +import ( + "context" + "database/sql" + "errors" + "flag" + "fmt" + "log" + "os" + "strings" + "time" + + _ "github.com/lib/pq" + + mclient "github.com/Molecule-AI/molecule-monorepo/platform/internal/memory/client" + "github.com/Molecule-AI/molecule-monorepo/platform/internal/memory/contract" + "github.com/Molecule-AI/molecule-monorepo/platform/internal/memory/namespace" +) + +const defaultLimit = 1000000 // effectively unlimited; cap keeps SQL pageable + +func main() { + if err := run(os.Args[1:], os.Stdout, os.Stderr); err != nil { + log.Fatalf("memory-backfill: %v", err) + } +} + +// run is extracted so tests can drive it with synthesized argv + +// captured stdout/stderr.

support multi-workspace external-agent registration (PR-1) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit External MCP agents (e.g. Claude Code installed on a company PC) can now register against MULTIPLE workspaces from a single process — the agent participates as a peer in workspace A (company) AND workspace B (personal) simultaneously, with one merged inbox tagged so replies route to the correct tenant. Use case (verbatim from operator): "I have this computer AI thats in company's PC, he is going to be put in company's workspace, but personally, I want to register it to my own workspace as well, so that I can talk to it and asking him to do work." ## What changed **Wire format** — new env var: MOLECULE_WORKSPACES='[ {"id":"","token":""}, {"id":"","token":""} ]' When set, mcp_cli iterates the array and spawns one (register + heartbeat + inbox poller) trio per workspace. Single-workspace mode (WORKSPACE_ID + MOLECULE_WORKSPACE_TOKEN) is unchanged — every existing operator's setup keeps working bit-for-bit. **Per-workspace token registry** (platform_auth.py): register_workspace_token(wsid, tok) — populated by mcp_cli once per workspace before any thread spawns; thread-safe registration + lock-free reads on the hot path. auth_headers(workspace_id=...) routes to the per-workspace token; auth_headers() with no arg uses the legacy resolution path unchanged (back-compat). **Per-workspace inbox cursors** (inbox.py): InboxState now supports cursor_paths={wsid: Path,...}. Each poller advances its own cursor — one workspace's slow poll can't stall another, and a 410 only resets the affected workspace's cursor. Single-workspace constructor (cursor_path=Path(...)) still works exactly as before via __post_init__ promotion to the empty-string key. Cursor filenames disambiguated by workspace_id[:8] when multi-workspace; single-workspace keeps the legacy filename so upgrade doesn't invalidate on-disk state. **Arrival workspace tagging** (inbox.py): InboxMessage.arrival_workspace_id — tells the agent which OF ITS workspaces the inbound message arrived on. Set by the poller from the cursor key. to_dict() omits the field when empty so single- workspace consumers see no shape change. **Reply routing** (a2a_tools.py + a2a_mcp_server.py + registry.py): send_message_to_user(workspace_id=...) — optional override that selects which workspace's /notify endpoint to POST to (and which token authenticates). Multi-workspace agents pass the inbound message's arrival_workspace_id; single-workspace agents omit it and route to the only registered workspace via the legacy URL. ## Out of scope (future PRs) - PR-2: cross-workspace delegation auto-routing — when an agent receives a request from personal-ws "delegate to ops-bot" and ops-bot lives in company-ws, the agent should auto-pick its company-ws identity for the outbound delegate_task. Today the agent must pass via_workspace explicitly (or fall through to primary workspace). - PR-3: memory namespacing — commit_memory() still writes to the primary workspace's memory regardless of inbound context. Will revisit when the new memory system (PR #2733 just landed) settles. ## Tests workspace/tests/test_mcp_cli_multi_workspace.py — 24 new tests: * MOLECULE_WORKSPACES JSON parsing (valid + 6 error shapes) * Token registry register / lookup / rotation / clear * auth_headers routing by workspace_id with legacy fallback * Per-workspace cursor save/load/reset isolation * arrival_workspace_id present-when-set, omitted-when-empty * default_cursor_path namespacing All 110 pre-existing tests in test_mcp_cli.py / test_inbox.py / test_platform_auth.py still pass — back-compat is mechanical. Refs: project memory entry "External agent multi-workspace registration", design questions answered 2026-05-04 by user (JSON env var; explicit memory writes deferred to PR-3).

MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit PR-1's auth_headers added an optional workspace_id parameter for multi-workspace token routing; the signature drift gate (test_platform_auth_signature_matches_snapshot) caught the change as expected. Snapshot regenerated to capture the new shape — diff is visible in the PR for reviewers + template repos that depend on this surface.

Adds the operator-controlled cutover flag that flips admin export/import from the legacy direct-DB path to the v2 plugin path. Activation: MEMORY_V2_CUTOVER=true AND the v2 plugin is wired via WithMemoryV2. Both must be true to take the new path; either being false falls through to the existing legacy SQL code unchanged. What ships: * AdminMemoriesHandler gains plugin + resolver fields, wired via WithMemoryV2 (production) / withMemoryV2APIs (tests) * Export: enumerates workspaces, asks resolver for each one's readable namespaces, searches each via plugin, deduplicates by memory id, applies SAFE-T1201 redaction on emitted content (F1084 parity). Returns the legacy memoryExportEntry shape so existing tooling keeps working. * Import: scope→namespace translation mirrors PR-6 shim. Uses UpsertNamespace + CommitMemory; runs SAFE-T1201 redaction BEFORE the plugin sees the content (F1085 parity). * Helpers: legacyScopeFromNamespace + namespaceKindFromLegacyScope (lifted out so admin_memories doesn't depend on MCP handler helpers). skipImport typed error. Operational rollout (cutover sequencing): 1. Today: MEMORY_V2_CUTOVER unset → legacy DB path. 2. After PR-7 backfill applied + smoke verified: operator sets MEMORY_V2_CUTOVER=true. 3. From that point, admin export/import operate on plugin storage; legacy agent_memories table is read-only for the ~60-day grace window before PR-9 drops it. Coverage on new paths: * cutoverActive: 100% * WithMemoryV2 / withMemoryV2APIs: 100% * importViaPlugin: 100% * exportViaPlugin: 97.2% (one defensive scan-error branch in the workspace-list loop) * scopeToWritableNamespaceForImport: 76.9% (resolver-error and no-matching-kind branches exercised end-to-end via Import) * legacyScopeFromNamespace + namespaceKindFromLegacyScope: 100% Edge cases pinned: * Cutover flag matrix (env unset/true/false × wired/unwired) * Export deduplicates memories shared across team (one row per id) * Export tolerates per-workspace failures (resolver / plugin) and keeps going on the rest * Export returns 500 only when the top-level workspace query fails * Empty readable namespaces → empty export (no panic) * Export redacts secrets in plugin path * Import: unknown workspace skipped, unknown scope skipped, plugin upsert/commit errors counted as errors * Import redacts secrets BEFORE plugin sees content * Legacy export/import path unchanged when cutover flag unset --- .../internal/handlers/admin_memories.go | 267 +++++++- .../handlers/admin_memories_cutover_test.go | 604 ++++++++++++++++++ 2 files changed, 870 insertions(+), 1 deletion(-) create mode 100644 workspace-server/internal/handlers/admin_memories_cutover_test.go diff --git a/workspace-server/internal/handlers/admin_memories.go b/workspace-server/internal/handlers/admin_memories.go index 0f564414..460eab15 100644 --- a/workspace-server/internal/handlers/admin_memories.go +++ b/workspace-server/internal/handlers/admin_memories.go @@ -1,23 +1,82 @@ package handlers import ( + "context" "log" "net/http" + "os" + "strings" "time" "github.com/Molecule-AI/molecule-monorepo/platform/internal/db" + mclient "github.com/Molecule-AI/molecule-monorepo/platform/internal/memory/client" + "github.com/Molecule-AI/molecule-monorepo/platform/internal/memory/contract" + "github.com/Molecule-AI/molecule-monorepo/platform/internal/memory/namespace" "github.com/gin-gonic/gin" ) +// envMemoryV2Cutover gates whether admin export/import routes through +// the v2 plugin (PR-8 / RFC #2728).

Builds on PR-1..10 (all merged or queued). Proves the central design property of the plugin contract: ANY plugin satisfying the v1 OpenAPI spec works as a drop-in replacement for the built-in postgres plugin. If this test fails after a refactor, the contract has drifted in a way that breaks ecosystem plugins. What ships: * internal/memory/e2e/swap_test.go — five E2E tests against a deliberately minimal "flat-memory" stub plugin (~50 LOC, single map, zero capabilities) * MCPHandler.Dispatch — small exported wrapper around dispatch so out-of-package E2E tests can drive tools by name without duplicating the whole MCP RPC stack E2E coverage: * TestE2E_FlatPluginRoundTrip: full lifecycle - list_writable_namespaces returns 3 entries - commit_memory_v2 writes through plugin - search_memory finds it back - commit_summary writes a summary - forget_memory deletes - search after forget excludes the deleted memory * TestE2E_LegacyShimRoutesThroughFlatPlugin: PR-6 shim wired up - Legacy commit_memory(scope=LOCAL) ends up in plugin storage - Legacy recall_memory finds it back through plugin search - Response shapes preserved (scope:LOCAL stays scope:LOCAL) * TestE2E_OrgMemoriesDelimiterWrap: prompt-injection mitigation - Org-namespace memory committed - Audit INSERT into activity_logs verified - Search returns content with [MEMORY id=... scope=ORG ns=...] prefix applied * TestE2E_StubPluginCapabilitiesAreEmpty: capability negotiation - Stub plugin reports zero capabilities - Client.SupportsCapability returns false for FTS, embedding - Confirms graceful degradation when plugin doesn't support a feature * TestE2E_PluginUnreachable_AgentSeesClearError: failure surface - Plugin URL pointing at bogus port - commit_memory_v2 returns informative error - No nil-pointer dereference; error message is actionable The flat plugin is intentionally minimal — it has no namespaces table distinct from memory records, no FTS, no semantic search, no TTL. The test proves operators can drop in a 50-line plugin and the agent behavior is identical (modulo capability-gated features). --- workspace-server/internal/handlers/mcp.go | 8 + .../internal/memory/e2e/swap_test.go | 440 ++++++++++++++++++ 2 files changed, 448 insertions(+) create mode 100644 workspace-server/internal/memory/e2e/swap_test.go diff --git a/workspace-server/internal/handlers/mcp.go b/workspace-server/internal/handlers/mcp.go index 9126955f..44290487 100644 --- a/workspace-server/internal/handlers/mcp.go +++ b/workspace-server/internal/handlers/mcp.go @@ -439,6 +439,14 @@ func (h *MCPHandler) dispatchRPC(ctx context.Context, workspaceID string, req mc // Tool dispatch // ───────────────────────────────────────────────────────────────────────────── +// Dispatch is the public entry point external code (tests, future +// out-of-package callers) uses to invoke a tool by name.

PR-1 (#2739) landed per-workspace auth + heartbeat + inbox. This PR threads ``source_workspace_id`` through the A2A client + tool surface so an agent registered against multiple workspaces can list peers across all of them and delegate from a specific source. Changes ------- * ``a2a_client``: ``discover_peer``, ``send_a2a_message``, ``get_peers_with_diagnostic``, and ``enrich_peer_metadata`` now accept ``source_workspace_id``. Routing uses it for both the X-Workspace-ID header and (transitively, via ``auth_headers(src)``) the bearer token. Defaults to module-level WORKSPACE_ID for back-compat. * ``a2a_client._peer_to_source``: a new lock-free cache mapping each discovered peer back to the source workspace whose registry surfaced it. ``tool_list_peers`` populates the cache on every call; ``tool_delegate_task`` consults it for auto-routing. * ``a2a_tools.tool_list_peers(source_workspace_id=None)``: when multiple workspaces are registered (MOLECULE_WORKSPACES) and no explicit source is passed, aggregates peers across every registered workspace and tags each entry with ``via: ``. Single-workspace mode is unchanged — no ``via:`` annotation, same output shape. * ``a2a_tools.tool_delegate_task`` and ``tool_delegate_task_async`` resolve source via ``source_workspace_id arg → _peer_to_source[target] → WORKSPACE_ID``. Agents almost never need to specify ``source_*`` explicitly — call ``list_peers`` first and the cache handles the rest. * ``tool_delegate_task_async`` idempotency key now includes the source workspace, so the same task delegated from two registered workspaces produces two distinct delegations (the right behavior — one per tenant audit trail). * ``platform_auth.list_registered_workspaces()``: new helper for the tool layer to enumerate the multi-ws registry. Lock-free reads matched by the existing single-writer-per-workspace contract from PR-1. * ``platform_auth.self_source_headers``: now passes ``workspace_id`` through to ``auth_headers`` — without this, a multi-workspace POST source-tagged with ``X-Workspace-ID=ws_b`` was authenticating with ws_a's token (or no token if MOLECULE_WORKSPACE_TOKEN unset). Latent PR-1 bug exposed by the new tool surface. * ``a2a_mcp_server`` tool dispatch passes ``source_workspace_id`` from the tool call arguments. * ``platform_tools.registry``: add ``source_workspace_id`` to the delegate_task, delegate_task_async, check_task_status, list_peers input schemas with copy explaining when to use it (rarely — the cache handles it). Tests (15 new, all passing) --------------------------- ``test_a2a_multi_workspace.py``: * TestDiscoverPeerSourceRouting (3): src arg drives header+token, fallback to module ws when omitted, invalid target short-circuits before any HTTP attempt. * TestSendA2AMessageSourceRouting (1): X-Workspace-ID source header + Authorization bearer both come from the source arg via the patched self_source_headers chain. * TestGetPeersSourceRouting (1): URL path AND headers use the source workspace id. * TestToolListPeersAggregation (4): aggregates across multiple registered workspaces, tags origin, leaves single-workspace path unchanged, explicit src arg overrides aggregation, diagnostic joining when every workspace returns empty. * TestToolDelegateTaskAutoRouting (3): cache-driven auto-route, explicit override beats cache, single-workspace fallback to module WORKSPACE_ID. * TestListRegisteredWorkspaces (3): registry enumeration helper. Plus ``tests/snapshots/a2a_instructions_mcp.txt`` regenerated to absorb the new ``source_workspace_id`` schema entries. Back-compat ----------- Every change defaults ``source_workspace_id=None``; legacy single-workspace operators (no MOLECULE_WORKSPACES) see identical behavior — same URLs, same headers, same tool output. The 24 PR-1 tests + 125 existing A2A tests all still pass. Out of scope (PR-3) ------------------- Memory namespacing per registered workspace lands after the new memory system v2 PR (#2740) settles in production.

CI's pytest harness pre-sets WORKSPACE_ID=test in the env before test collection, so a2a_client's module-level WORKSPACE_ID (captured at import time, line 24) holds "test" — but the local fixture's

Fix is contract-level: extend MemoryWrite with an optional `id` idempotency key. When supplied, the plugin MUST treat the write as upsert keyed on this id; when omitted, the plugin generates a fresh UUID (production agent commits keep working unchanged). Changes: * docs/api-protocol/memory-plugin-v1.yaml: add id field with description that flags it as idempotency key * internal/memory/contract/contract.go: add ID to MemoryWrite struct, update memory_write_minimal golden vector * internal/memory/pgplugin/store.go: split CommitMemory into two paths — upsert when body.ID set (INSERT ... ON CONFLICT (id) DO UPDATE), plain INSERT otherwise * cmd/memory-backfill/main.go: pass agent_memories.id to MemoryWrite, fix the false comment about 409 deduplication New tests: * pgplugin: TestCommitMemory_WithIDUpserts pins the upsert SQL is used when id is set; TestCommitMemory_UpsertScanError covers the error branch * backfill: TestBackfill_PassesSourceUUIDAsIdempotencyKey pins the forwarding behavior; TestBackfill_RerunIsIdempotent simulates a retry and asserts both runs pass the same uuid (plugin upsert is what makes this safe) Why this matters: operators retrying a failed backfill (which they will — networks fail, transactions abort) would otherwise create N duplicates per memory. The duplicates aren't visible until search results show obvious dupes — debugging that under prod load is bad. Production agent commits are unaffected: they leave id empty, the plugin generates a fresh UUID via gen_random_uuid(), zero behavior change for the hot path. --- docs/api-protocol/memory-plugin-v1.yaml | 9 +++ workspace-server/cmd/memory-backfill/main.go | 12 +++- .../cmd/memory-backfill/main_test.go | 72 ++++++++++++++++++- .../internal/memory/contract/contract.go | 7 ++ .../internal/memory/pgplugin/handlers_test.go | 40 +++++++++++ .../internal/memory/pgplugin/store.go | 39 ++++++++++ 6 files changed, 173 insertions(+), 6 deletions(-) diff --git a/docs/api-protocol/memory-plugin-v1.yaml b/docs/api-protocol/memory-plugin-v1.yaml index 92c8842b..95884f58 100644 --- a/docs/api-protocol/memory-plugin-v1.yaml +++ b/docs/api-protocol/memory-plugin-v1.yaml @@ -238,6 +238,15 @@ components: type: object required: [content, kind, source] properties: + id: + type: string + format: uuid + nullable: true + description: | + Optional idempotency key.

The peer-discovery-404 harness replay stubbed both with 0-arg lambdas, so the helper call inside the replay raised: TypeError: () takes 0 positional arguments but 1 was given …and the diagnostic captured by the replay was the TypeError text, not the platform-404 string the assertion grep'd for. Caught by PR-2737 (auto-promote staging→main) — the replay went red right after #2743 merged into staging. Switching both stubs to ``*args, **kwargs`` makes them tolerant of both the legacy 0-arg call shape AND the new 1-arg-with-workspace call shape, so neither the harness nor the in-tree unit tests need to know which version of the runtime helpers ran the call.

I1: expires_at silent drop - mcp_tools_memory_v2.go:130 had `if t, err := ...; err == nil { ... }` which dropped malformed timestamps without telling the agent. Agent passes `expires_at: "tomorrow"`, gets a 200, and the memory has no TTL. - Now returns a clear error: "invalid expires_at: must be RFC3339" - Test renamed: TestCommitMemoryV2_BadExpiresIsIgnored (which codified the bug) → TestCommitMemoryV2_BadExpiresReturnsError (which pins the fix). I4: audit log JSON via Sprintf-%q - auditOrgWrite was building activity_logs.metadata via fmt.Sprintf with %q. Go-quoted strings happen to coincide with JSON-quoted for ASCII (and today's values are pure ASCII: UUID + hex digest) so the bug was latent. - Replaced with json.Marshal of map[string]string. Same wire shape today, but won't silently produce invalid JSON if metadata grows to include arbitrary content snippets. - New test TestAuditOrgWrite_MetadataIsValidJSON uses a custom sqlmock.Argument matcher (jsonValidMatcher) that fails the test if the metadata column isn't parseable JSON. The test runs auditOrgWrite with a content string containing quotes, backslashes, and a control byte — values where %q would diverge from JSON-quote. Both pre-existing tests (TestCommitMemoryV2_AuditsOrgWrites etc.) remain green. --- .../internal/handlers/mcp_tools_memory_v2.go | 23 +++++-- .../handlers/mcp_tools_memory_v2_test.go | 68 ++++++++++++++++--- 2 files changed, 79 insertions(+), 12 deletions(-) diff --git a/workspace-server/internal/handlers/mcp_tools_memory_v2.go b/workspace-server/internal/handlers/mcp_tools_memory_v2.go index 7bd0f1b3..00c99152 100644 --- a/workspace-server/internal/handlers/mcp_tools_memory_v2.go +++ b/workspace-server/internal/handlers/mcp_tools_memory_v2.go @@ -127,9 +127,11 @@ func (h *MCPHandler) toolCommitMemoryV2(ctx context.Context, workspaceID string, Source: contract.MemorySourceAgent, } if exp, ok := args["expires_at"].(string); ok && exp != "" { - if t, err := time.Parse(time.RFC3339, exp); err == nil { - body.ExpiresAt = &t + t, err := time.Parse(time.RFC3339, exp) + if err != nil { + return "", fmt.Errorf("invalid expires_at: must be RFC3339 (got %q): %w", exp, err) } + body.ExpiresAt = &t } if pin, ok := args["pin"].(bool); ok { body.Pin = pin @@ -331,10 +333,23 @@ func (h *MCPHandler) toolForgetMemory(ctx context.Context, workspaceID string, a func (h *MCPHandler) auditOrgWrite(ctx context.Context, workspaceID, ns, content, memID string) error { hash := sha256.Sum256([]byte(content)) hashHex := hex.EncodeToString(hash[:]) - _, err := h.database.ExecContext(ctx, ` + // json.Marshal, not Sprintf-%q. %q produces Go-quoted strings, + // which are NOT valid JSON for non-ASCII inputs (Go's escapes + // like \xNN aren't part of the JSON spec).

This wave fixes +all of them. Order matches operator-impact severity. + +### Critical: backfill idempotency via `MemoryWrite.id` (#2744) + +**The bug.** The backfill CLI claimed idempotent on re-run, but +`gen_random_uuid()` in the plugin's INSERT meant every retry created +a fresh row. Operators retrying a failed `-apply` would silently +double their memory count. + +**The fix.** Optional `id` field on `MemoryWrite`. When supplied, +plugins MUST upsert. The backfill now forwards `agent_memories.id` +to `MemoryWrite.id`, so retries update in place. + +**Plugin author action.** If your plugin uses +`INSERT INTO ... DEFAULT gen_random_uuid()`, switch to +`INSERT ... ON CONFLICT (id) DO UPDATE` when `id` is set. The wire +contract is forward-compatible — plugins that ignore the field still +work for production agent commits (which leave `id` empty), but they +will silently corrupt backfill retries. + +### Critical: `memory-backfill -verify` mode (#2747) + +**The miss.** The original PR-7 task spec called for a parity-check +mode but it never landed. Operators had no way to confirm a +migration succeeded short of "no errors logged." + +**The fix.** New `-verify` flag samples N workspaces, queries +`agent_memories` direct, runs an equivalent plugin search via the +namespace resolver, multiset-compares contents. Reports mismatches +to stdout and exits non-zero so CI can gate the cutover. + +```bash +memory-backfill -verify # default sample 50 +memory-backfill -verify -verify-sample=200 # bigger +memory-backfill -verify -workspace= # one workspace +``` + +### Important: `expires_at` validation (#2746) + +**The bug.** `commit_memory_v2` silently dropped malformed +`expires_at` strings. Agent passes `expires_at: "tomorrow"`, gets a +200, memory has no TTL — agent thinks it set a TTL, didn't. + +**The fix.** Returns +`fmt.Errorf("invalid expires_at: must be RFC3339")` on parse +failure. Plugin is not called in this case. + +**Plugin author action.** None — this is a workspace-server-side +fix. But: if your plugin advertises the `ttl` capability, make sure +you actually evict expired rows on read (not just on a janitor cron +that runs once a day). The harness in `testing-your-plugin.md` has +a TTL-eviction test you should run. + +### Important: audit log JSON via `json.Marshal` (#2746) + +**The bug.** `auditOrgWrite` built `activity_logs.metadata` via +`fmt.Sprintf` with `%q`. For ASCII (today's UUID + hex digest) this +coincidentally produces valid JSON; for unicode or control bytes it +silently produces non-JSON. + +**The fix.** Replaced with `json.Marshal(map[string]string{...})`. +Same wire shape today, won't regress when metadata grows. + +**Plugin author action.** None — workspace-server-internal. + +### Operator action: staging verification (#292) + +**Status.** Tracked as task #292.

When a workspace is hard-purged, its `workspace:` namespace stays in the plugin storage. Over time deleted workspaces accumulate as orphan namespaces. Fix: optional namespaceCleanupFn hook on WorkspaceHandler. The purge path (workspace_crud.go ~line 520) iterates each purged id and calls the hook best-effort. main.go wires the hook to plugin.DeleteNamespace when MEMORY_PLUGIN_URL is set; operators who haven't enabled the plugin keep the no-op default. Why a hook (not direct plugin import): * Keeps WorkspaceHandler decoupled from the memory contract package (easier to test, smaller blast radius if the contract bumps) * Tests inject a captureCleanupHook stub without standing up a real plugin client * Production wiring stays a one-liner in main.go What gets cleaned up: * `workspace:` for each purged workspace * NOT `team:` / `org:` — those may still be referenced by other workspaces under the same root, so dropping them on a single workspace's purge would orphan team/org data for the survivors. Operator can purge those manually after confirming the entire root is gone. What stays untouched: * Soft-removed workspaces (status='removed', no ?purge=true). The grace window is by design — the data should still be there if the operator unremoves.

This adds the actual real-subprocess test: build the binary with `go build`, start it pointing at real postgres, drive HTTP via the real client. What in-process tests miss that this catches: - Binary build / boot-path panics (env var typos, mixed-key interface bugs that only surface when start() runs) - Wire encoding bugs that sqlmock smooths over (the pq.Array regression from PR-3 development would have been caught here) - HTTP+TCP-socket edge cases - Real upsert behavior under postgres ON CONFLICT (C1 fix) Build-tag gated so default CI doesn't require docker: go test -tags memory_plugin_e2e -v ./cmd/memory-plugin-postgres/ Tests skip silently when MEMORY_PLUGIN_E2E_DB is unset.
