Merge origin/main into MR-656; retrofit + fold-in run_query
Resolves the 4 hard conflicts from PR #119 (multi-graph server mode,
MR-668) landing on main:

* `crates/omnigraph-cli/src/main.rs` imports: drop unused `ChangeRequest`,
  take main's `GraphListResponse`.
* `crates/omnigraph-server/src/api.rs`: keep branch's `ChangeRequest`
  field rename (`query_source` -> `query` with serde alias, `query_name`
  -> `name`); accept main's rustfmt.
* `crates/omnigraph-server/src/lib.rs`: take both import lists (branch's
  `QueryRequest` + main's `GraphInfo`/`GraphListResponse`); rewrite the
  `server_change` signature to combine the branch's `run_mutate`
  extraction with main's `Extension<Arc<GraphHandle>>` + `ResolvedActor`
  parameter shape.
* `docs/user/server.md`: re-apply the branch's new `/query` and `/mutate`
  rows plus deprecation notes for `/read` and `/change` on top of main's
  two-column (single-mode | multi-mode) table layout.

Auto-merged but stale callsites repaired alongside the conflict
resolutions so the merge commit compiles:

* `server_query` handler now takes `Extension(handle): Extension<Arc<GraphHandle>>`
  and `Option<Extension<ResolvedActor>>`, with policy read from
  `handle.policy.as_deref()` instead of the removed `state.policy_engine()`.

Fold-in for MR-969 (next-step seam):

* Extract `run_query` mirroring `run_mutate`: both helpers now take
  `(state, handle, actor, query: &str, name: Option<&str>,
  params_json: Option<&Value>, branch, ...)` instead of the
  `QueryRequest` / `ChangeRequest` body type. The future
  `/queries/{name}` handler can call these with registry-supplied
  fields without rebuilding the request shape.
* `server_query` / `server_read` now route through `run_query`;
  `server_mutate` / `server_change` route through `run_mutate`.
* D2 mutation rejection on `/query` is preserved via the
  `reject_mutations` flag; `/read` keeps the legacy permissive
  behavior for byte-stable back-compat.

`cargo test -p omnigraph-server --test server`: 89 passed, 0 failed.
`cargo build --workspace --tests --locked`: clean.

CLI Guide

Core Graph Flow

omnigraph init --schema ./schema.pg ./graph.omni
omnigraph load --data ./data.jsonl --mode overwrite ./graph.omni
omnigraph snapshot ./graph.omni --branch main --json
omnigraph query  --uri ./graph.omni --query ./queries.gq --name get_person --params '{"name":"Alice"}'
omnigraph mutate --uri ./graph.omni --query ./queries.gq --name insert_person --params '{"name":"Mina","age":28}'

omnigraph query is the canonical read command (pairs with POST /query); omnigraph mutate is the canonical write command (pairs with POST /mutate). The previous names omnigraph read and omnigraph change keep working as visible aliases — invocations emit a one-line deprecation warning to stderr and otherwise behave identically. See Deprecated names for the migration table.

For ad-hoc reads and mutations (REPLs, AI agents, one-off scripts), pass the GQ source inline with -e / --query-string instead of a file path:

omnigraph query --uri ./graph.omni \
  -e 'query find($name: String) { match { $p: Person { name: $name } } return { $p.name, $p.age } }' \
  --params '{"name":"Alice"}'

omnigraph mutate --uri ./graph.omni \
  -e 'query add($name: String, $age: I32) { insert Person { name: $name, age: $age } }' \
  --params '{"name":"Inline","age":42}'

-e is mutually exclusive with --query <path> and --alias <name>; exactly one of the three must be provided. The inline source travels through the same parser, lint, params binding, and commit machinery as a file-based query — only the source loader changes.

Branching And Reviewable Data Flows

omnigraph branch create --uri ./graph.omni --from main feature-x
omnigraph branch list --uri ./graph.omni
omnigraph branch merge --uri ./graph.omni feature-x --into main

omnigraph ingest --data ./batch.jsonl --branch review/import-2026-04-09 ./graph.omni
omnigraph export ./graph.omni --branch main --type Person > people.jsonl
omnigraph commit list ./graph.omni --branch main --json
omnigraph commit show --uri ./graph.omni <commit-id> --json

Remote Server Mode

Serve a graph:

omnigraph-server ./graph.omni --bind 127.0.0.1:8080

Read through the HTTP API:

omnigraph query \
  --target http://127.0.0.1:8080 \
  --query ./queries.gq \
  --name get_person \
  --params '{"name":"Alice"}'

If the server requires auth, set OMNIGRAPH_SERVER_BEARER_TOKEN on the server and configure the matching bearer_token_env in omnigraph.yaml.

Multi-graph servers (v0.6.0+)

Against a multi-graph server (started with --config omnigraph.yaml referencing a non-empty graphs: map), use omnigraph graphs list to enumerate the registered graphs. The server must configure bearer tokens and server.policy.file with a rule that allows graph_list; /graphs is closed by default even when the server runs with --unauthenticated.

OMNIGRAPH_BEARER_TOKEN=admin-token \
  omnigraph graphs list --uri http://server.example.com --json

For config-driven clients, set the remote graph's bearer_token_env to an environment variable containing a token whose actor is authorized by server.policy.file.

list rejects local URI targets — it's for remote multi-graph servers only.

Runtime add/remove is not in v0.6.0. To add a graph, stop the server, add a graphs.<id> entry to omnigraph.yaml, then restart. To remove, stop the server, delete the entry, restart.

Per-graph URLs: hit a graph's cluster route from any subcommand by pointing --uri at it:

omnigraph read --uri http://server.example.com/graphs/beta --query ./q.gq ...

Runs, Policy, And Diagnostics

omnigraph lint  --query ./queries.gq --schema ./schema.pg --json
omnigraph check --query ./queries.gq ./graph.omni --json

omnigraph schema plan --schema ./next.pg ./graph.omni --json
omnigraph schema apply --schema ./next.pg ./graph.omni --json
omnigraph policy validate --config ./omnigraph.yaml
omnigraph policy test --config ./omnigraph.yaml
omnigraph policy explain --config ./omnigraph.yaml --actor act-alice --action read --branch main

omnigraph commit list ./graph.omni --json
omnigraph commit show --uri ./graph.omni <commit-id> --json

(The legacy omnigraph run list/show/publish/abort subcommands were removed in MR-771; mutations and loads publish atomically and the commit graph (omnigraph commit list) is the audit surface.)

query lint and query check are the same command surface. In v1, graph-backed lint uses local or s3:// graph URIs; HTTP targets are only supported when you also pass --schema.

Config

omnigraph.yaml lets the CLI and server share named graphs, defaults, and query roots:

graphs:
  local:
    uri: ./demo.omni
  dev:
    uri: http://127.0.0.1:8080
    bearer_token_env: OMNIGRAPH_BEARER_TOKEN

cli:
  graph: local
  branch: main

query:
  roots:
    - queries
    - .

The config file can also define:

  • server bind defaults
  • auth env files
  • query aliases for common read and change commands
  • policy.file for Cedar authorization rules

When policy is enabled, schema apply is authorized through the schema_apply action and is typically limited to admins on protected main.

Deprecated names

The CLI was renamed to align with the HTTP server's canonical endpoint names (POST /query, POST /mutate) and the query keyword in the GQ language. The previous spellings keep working forever; invocations emit a one-line warning to stderr and otherwise behave identically.

Old (deprecated) New (canonical) Migration
omnigraph read omnigraph query Same flags and behavior. read is a visible clap alias.
omnigraph change omnigraph mutate Same flags and behavior. change is a visible clap alias.
omnigraph query lint omnigraph lint Same flags. The argv-level shim rewrites query lint to lint.
omnigraph query check omnigraph check check is a visible alias of omnigraph lint.

The command: field in aliases.<name> in omnigraph.yaml accepts both read / change (legacy) and query / mutate (canonical); the two spellings are interchangeable on the wire via serde aliases.
