Devin AI a3e1b27a63 feat(MR-656): rename read/change to query/mutate with deprecation signals
HTTP server:
- Add POST /mutate as canonical write endpoint (pairs with POST /query).
- Mark POST /read and POST /change as deprecated. Three-channel signal:
  * OpenAPI: `deprecated: true` on the operation (every codegen flags
    the generated SDK method).
  * RFC 9745: response `Deprecation: true` header on every response.
  * RFC 8288: response `Link: </successor>; rel="successor-version"`
    pointing at /query and /mutate respectively.
- Share business logic across /mutate and /change via run_mutate(); the
  /change wrapper is the only place that adds the deprecation headers.
- ChangeRequest field aliases (query_source/query_name) preserved.
- AliasCommand serde now accepts `query`/`mutate` alongside `read`/`change`.

CLI:
- Promote `omnigraph query` / `omnigraph mutate` to top-level canonical
  subcommands (clap visible_alias keeps `omnigraph read` / `omnigraph
  change` working forever).
- Promote `omnigraph lint` / `omnigraph check` to top-level (was nested
  under `omnigraph query lint`, which is now a deprecated argv shim that
  rewrites to the canonical form).
- Argv-level preprocessing prints a one-line deprecation warning to
  stderr when any legacy spelling is used. Canonical names are silent.

Tests:
- Server: /mutate works, /change emits Deprecation+Link headers, /read
  emits Deprecation+Link headers, /query carries no deprecation signal.
- OpenAPI: /read and /change flagged deprecated; /query and /mutate not.
- CLI: canonical `lint` matches deprecated `query lint` / `query check`
  output; `read` / `change` print deprecation warnings.

Docs:
- cli.md: new canonical examples; "Deprecated names" migration table.
- cli-reference.md: top-level table updated; aliases.<name>.command
  accepts both legacy and canonical spellings.
- server.md: endpoint inventory shows /query and /mutate as canonical
  and /read and /change as deprecated; dedicated section explains the
  three-channel deprecation signal.
- og-cheet-sheet.md: use new `omnigraph lint` / `omnigraph check`.
- openapi.json regenerated.

Migration is purely cosmetic — every deprecated form continues to work
indefinitely; only the spelling changes.

CLI Guide

Core Repo Flow

omnigraph init --schema ./schema.pg ./repo.omni
omnigraph load --data ./data.jsonl --mode overwrite ./repo.omni
omnigraph snapshot ./repo.omni --branch main --json
omnigraph query  --uri ./repo.omni --query ./queries.gq --name get_person --params '{"name":"Alice"}'
omnigraph mutate --uri ./repo.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 ./repo.omni \
  -e 'query find($name: String) { match { $p: Person { name: $name } } return { $p.name, $p.age } }' \
  --params '{"name":"Alice"}'

omnigraph mutate --uri ./repo.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 ./repo.omni --from main feature-x
omnigraph branch list --uri ./repo.omni
omnigraph branch merge --uri ./repo.omni feature-x --into main

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

Remote Server Mode

Serve a repo:

omnigraph-server ./repo.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.

Runs, Policy, And Diagnostics

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

omnigraph schema plan --schema ./next.pg ./repo.omni --json
omnigraph schema apply --schema ./next.pg ./repo.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 ./repo.omni --json
omnigraph commit show --uri ./repo.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, repo-backed lint uses local or s3:// repo 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.
