The POST /graphs runtime-create endpoint shipped in PR 7/10 has three
unresolved high-severity bugs:
- flock-on-renamed-inode race: the YAML flock is taken on
omnigraph.yaml itself, then a temp file is renamed over it.
Cross-process writers end up locking different inodes — both
believing they hold exclusive access.
- duplicate-check outside the file lock: precheck runs against
the in-memory registry only; the locked closure does
config.graphs.insert(...) unconditionally. Concurrent same-id
POSTs can persist the loser in YAML while the in-memory registry
keeps the winner — they disagree after restart.
- best_effort_cleanup_init_artifacts deletes _schema.pg /
_schema.ir.json / __schema_state.json on any init failure. An
accidental re-init against an existing graph's URI destroys its
schema; subsequent open() fails at read_text(_schema.pg).
The correct fix is a Lance-style cluster catalog (reserve → init →
publish with recovery sidecars), parallel to the engine's existing
__manifest discipline. That work is out of scope for v0.7.0.
For now, disable runtime add/remove from the network and CLI surface.
Operators add graphs by editing omnigraph.yaml and restarting. The
GET /graphs read-only enumeration stays.
Removed:
- POST /graphs handler + router fragment + utoipa registration
- 13 post_graphs_* server tests + 3 composite POST tests +
multi_mode_app_with_real_config / post_graph helpers
- CLI omnigraph graphs create subcommand + its handler + cli.rs tests
- system_remote.rs combined list+create test trimmed to list-only
- YAML rewrite infra: rewrite_atomic[_with_modify], RewriteAtomicError,
staging_path, hash_config_file, AppState::config_hash field +
threading through new_multi and open_multi_graph_state
- fs2 dependency (verified absent from cargo tree)
- sha2/fs2 imports in config.rs (only the rewrite path used them)
- Cedar PolicyAction::GraphCreate variant + "graph_create" match arms
+ action def in Cedar schema + graph_create_action_authorizes_against_server_resource test
- GraphCreateRequest / GraphCreateResponse / GraphSchemaSpec /
GraphPolicySpec API types (only the POST handler / CLI imported them)
Kept:
- GET /graphs (read-only enumeration) and graph_list Cedar action
- omnigraph graphs list CLI subcommand
- All multi-graph startup, mode inference, cluster routes,
per-graph + server-level Cedar policies
- server_settings_drive_multi_graph_startup_end_to_end (the test
that covers operator-authored YAML + restart — the path that
survives)
- best_effort_cleanup_init_artifacts and the three init failpoints
(still reachable from CLI `omnigraph init`; preflight fix deferred
as a follow-up)
- GraphRegistry::insert and its concurrency tests — production
callers gone, but the method is the natural seam for the future
cluster-catalog work
Also fixed (transcript issue 4):
- ALWAYS_FLAT_PATHS now includes /graphs so multi-mode OpenAPI
advertises the management route correctly (was previously rewritten
to /graphs/{graph_id}/graphs)
- multi_mode_openapi_keeps_healthz_flat → renamed to
multi_mode_openapi_keeps_management_paths_flat, asserts both
/healthz and /graphs stay flat
- multi_mode_openapi_prefixes_operation_ids_with_cluster skips
/graphs in addition to /healthz
Doc fixes:
- docs/user/cli.md: graphs list example was --target http://...,
but --target is a config-graph-name lookup; corrected to --uri.
Removed the graphs create example.
- docs/user/server.md: dropped POST /graphs row, "omnigraph.yaml
ownership", and "POST /graphs body shape" sections. Added a
paragraph stating runtime add/remove is not exposed in v0.7.0.
- docs/user/policy.md: dropped graph_create action; reworded the
"Configuration" line to clarify that server-scoped rules (graph_list)
take neither branch_scope nor target_branch_scope.
- docs/releases/v0.7.0.md: rewrote release narrative — multi-graph
mode ships; runtime add/remove deferred.
- AGENTS.md: HTTP server bullet and capability matrix row updated to
reflect read-only GET /graphs and the operator-edit workflow.
- openapi.json regenerated; /graphs has only .get, no .post.
