- Agent lifecycle revocation is not enforced by HTTP Signature authorization; do not rely on removing or revoking an agent record to block a compromised signer.

- Read visibility is not a blanket data-classification boundary: task, IPFS-pin, and Arweave-anchor listings are not repository-gated; withheld path names can be visible to a root reader; and later visibility changes cannot retract content already announced or externally anchored.

- Peer writes are signed by upgraded nodes, but strict signed-peer enforcement is opt-in during rolling upgrades.

- GraphQL mutations require a signed identity (a verified signer bound to the acting DID) but are limited to the agent-task queue; repo writes are not exposed over GraphQL and remain REST-only.

- Current GraphQL mutations require an authenticated signer, but there is no mutation-specific guardrail that prevents a future mutation from omitting that check.

- Pull-request review comments do not yet have threaded line-level anchors, and merges do not enforce approval requirements.

Also bounds the withheld-blob classification walk (on both the upload-pack serve and receive-pack replication paths) and the push-side pin-candidate discovery (`rev-list` / `cat-file`), each reaped via process-group teardown at the deadline. On the path-scoped upload-pack path the classification walk and the pack serve share ONE deadline, so this value bounds their combined duration rather than granting each stage a full budget: a walk that consumes it leaves the serve nothing and the clone gets a 504. Serving large path-scoped repos may therefore need a higher value than they did when each stage was budgeted separately.

- GraphQL mutations require a verified signer (shipped, #87). Keep the surface limited to the agent-task queue; do not expose an owner-gated repo-write mutation over GraphQL without its owner-gate and REST parity. The `every_graphql_mutation_has_its_gate` fence forces any new mutation to be classified in its table (discovered from the schema, so none can slip in unlisted); the owner-gate and REST parity themselves stay the INV-1 review check, not something the fence proves.

- Add mutation-aware GraphQL auth before GraphQL becomes a public write API surface.

Live-network blockers to prioritize:
|
||||
|
||||
- GraphQL mutations now require a verified signer bound to the acting DID (#87), and the surface stays limited to the agent-task queue, so there is no public repo-write GraphQL API to gate. Queries remain open by design. (Resolved; kept here as posture, not a live blocker.)
|
||||
- GraphQL POST is still open for compatibility; GraphQL mutations should get mutation-aware auth before it becomes a public write API surface.
|
||||
- Push authorization is still not capability-complete. A valid DID signature is authentication, not authorization. Owner checks are now enforced on every branch, protected or not (`GITLAWB_ENFORCE_OWNER_PUSH`, on by default); what remains is that a UCAN `git/push` capability is not yet honored, so a delegated or CI key cannot push.
|
||||
- UCAN chain validation is incomplete and UCAN revocation/blocklisting is not implemented as an operator feature.
|
||||
- Private repository reads are not enforced. `is_public` and `GITLAWB_PUBLIC_READ` exist, but per-repository private-read behavior is not wired.
