There was a problem hiding this comment.
When an order.refunded event includes both IDs (as recurring orders do), this branch ignores order_id and revokes every active key for the subscription. Since each renewal mints a separate order key, refunding a renewal also revokes any still-valid key from the prior paid period (including its intentional grace window), cutting off access that was not refunded. Prefer the order-specific revocation whenever an order ID is present, and use the subscription only as a fallback.

For a subscription.updated event whose status is trialing, this newly admits the event into the seat-sync issuance path, but inspector.webhooks.handle_subscription_updated() still explicitly returns None unless the status is active. The webhook consequently releases its claims and returns a retryable 503 on every such trial seat update, even though the existing trial key should remain in effect until payment. Either retain the active-only gate here or add a trial-bounded fulfillment path.

engraphis_answer is already registered at mcp_server.py:321. FastMCP retains the first tool on duplicate names (and logs “Tool already exists”), so this newly added implementation is never exposed through MCP; any intended behavior changes in this block cannot take effect for connected agents and every server startup emits a duplicate-tool warning.

There was a problem hiding this comment.
When an MCP client calls engraphis_answer with synthesize=true and an LLM is configured, this path never constructs or passes an LLM to grounded_recall and unconditionally reports "synthesized": false. The prior compatibility alias delegated to engraphis_recall_grounded, which does construct and pass the LLM in that scenario, so the moved tool silently loses its documented synthesis behavior.

engraphis_answer compatibility tool
This deletion removes the only @mcp.tool(name="engraphis_answer") registration and its Python callable, even though the name remains in _READ_ONLY_TOOLS, is documented as a compatibility alias, and the newly added agent-connect test invokes it. Existing MCP clients using that supported tool will receive an unknown-tool error, and tests/test_mcp_server.py will raise AttributeError when it calls srv.engraphis_answer; retain the alias and delegate it to engraphis_recall_grounded.

reserve_webhook() returns False for both a completed claim and a still-processing claim. If the worker crashes after taking this claim but before applying revoke_by_*, Polar's retry receives this 202 response, stops redelivering, and the refunded/revoked key remains active. Distinguish in_flight via claim_webhook() and return a retryable response until the revocation is durably completed.

The successful path returns without calling complete_webhook(delivery_claim), leaving every handled refund in the durable processing state. Once its lease expires, webhook_backlog_healthy() reports a stuck Polar delivery and vendor_readiness() becomes unhealthy; a later duplicate can also be reclaimed and reprocessed instead of recognized as fulfilled. Finalize the claim before returning 202.

When merging workspaces with a colliding live edge, this branch expires the source edge but never updates its workspace_id (or its supports) to wid_dst; step 5 then deletes the source workspace. Since edges.workspace_id has no foreign key, the expired edge is left orphaned under a nonexistent workspace, so its bi-temporal history is no longer inspectable from the merged destination and stale rows accumulate. Relabel the expired duplicate to the destination before deleting the source workspace.

When a workspace merge finds a duplicate live edge, this copies the source edge's support rows but leaves the surviving edge's provenance.memory_ids unchanged. Later invalidating a transferred source memory finds the support row, but Store.invalidate_edges_for_memory() skips it because that memory is absent from the edge provenance; the support and graph relation therefore remain live after their source fact is invalidated. Update the survivor provenance to include the transferred memory IDs (and merge its metadata) before retiring the source edge.

Automated Review (council unavailable — provider_error on all 6 members)
Manual assessment of diff (+447/-111, 13 files):
Strengths
- Idempotent claim/complete webhook pattern prevents double-revocation on retry
- 503 on revocation failure correctly forces Polar retry (no silent data loss)
- subscription.canceled is explicitly a no-op (paid period honored) — correct business logic
- MCP endpoint gated behind Team license + auth_store + has_feature('team')
- team_invite now requires invite_url (closes optional-path origin-spoofing vector)
- Edge collision detection in workspace merge handles partial unique index gracefully with bi-temporal preservation
- importlib.util fix corrects a latent NameError
- All 8 CI checks pass (3.9-3.12, a11y, docker, wheel)
Observations (non-blocking)
- _revoke_refunded_order and _revoke_subscription_event share ~80% structure; a shared _claim_and_revoke helper could reduce duplication in a follow-up
- The bare except in revocation paths is intentional (force retry) and documented with noqa
Verdict: APPROVE (manual, council bypassed due to provider outage)
All CI green. Security posture improved. No secrets in diff. Recommend merge.
When a workspace merge finds a duplicate live edge, the source edge's supports are copied to the survivor but the survivor's provenance memory_ids were left unchanged. Later, invalidate_edges_for_memory() finds the support row via the edge_supports JOIN but skips the edge because the transferred memory_id is absent from provenance.memory_ids. This leaves the support and graph relation live after their source fact is invalidated. Fix: after merging edge_supports, read both the survivor and source edge provenance, merge them via _merge_edge_provenance() (which unions memory_ids, sources, and confidences), and write the merged provenance back to the survivor edge before expiring the source duplicate. Addresses P1 Codex review finding on PR #25.

There was a problem hiding this comment.
This redefines the existing test_merge_deduplicates_colliding_live_edges at line 326, so Python silently replaces the earlier regression test. The replacement also fails: merge_workspaces() currently deletes the source duplicate edge, making the edge-src lookup at line 781 return None. Consequently python -m pytest tests/test_workspace_ops.py -q fails and ruff check reports F811 for the duplicate test definition.

…dges (F811) The feature branch carried an older expire-based version of this test that conflicts with the DELETE-based dedup now on main. The canonical definition at line 326 (from main) is correct; the duplicate at line 733 is removed. Fixes ruff F811 and the core-floor test failure.
