MR-794 step 2: docs — runs/invariants/architecture/execution + cleanup

Refresh user-facing and agent-facing docs for the staged-write rewire
and clean up stale Run-state-machine references that survived MR-771.

MR-794-specific updates:
* docs/runs.md — remove "Known limitation: mid-query partial failure"
  section; document the in-memory accumulator + D₂ rule + the
  LoadMode::Overwrite residual.
* docs/invariants.md §VI.25 — flip from aspirational/open to
  upheld for inserts/updates. Within-query read-your-writes is now
  load-bearing for the publisher CAS contract.
* docs/architecture.md — add "Mutation atomicity — in-memory
  accumulator (MR-794)" subsection with per-op flow; refresh the
  engine + state diagrams to drop RunRegistry and add MutationStaging.
* docs/execution.md — rewrite the mutation flow sequence diagram
  for the staged-write path; updated the LoadMode table to call
  out per-mode commit semantics; rewrote load vs ingest.
* docs/query-language.md — document the D₂ parse-time rule.
* docs/errors.md — add the D₂ BadRequest rejection path.
* docs/testing.md — extend the runs.rs row to cover the new MR-794
  contract tests; add the staged_writes.rs row.
* docs/releases/v0.4.1.md (new) — release note covering the rewire,
  test additions, residuals, and files changed.
* AGENTS.md (CLAUDE.md symlink) — update the atomic-per-query
  description and the L2 capability matrix row.

Stale-reference cleanup (MR-771 leftovers):
* docs/storage.md — drop live _graph_runs.lance / _graph_run_actors.lance
  from the layout diagram and prose; mark legacy.
* docs/branches-commits.md — move __run__<id> to a legacy note;
  remove publish_run from the publish-trigger list.
* docs/audit.md — refresh _as API list (drop begin_run_as / publish_run_as);
  legacy RunRecord.actor_id moved to a historical note.
* docs/constants.md — mark run registry / branch-prefix rows as legacy.
* docs/cli.md — replace the legacy omnigraph run * quickstart block
  with omnigraph commit list/show.

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 read --uri ./repo.omni --query ./queries.gq --name get_person --params '{"name":"Alice"}'
omnigraph change --uri ./repo.omni --query ./queries.gq --name insert_person --params '{"name":"Mina","age":28}'

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 read \
  --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 query lint --query ./queries.gq --schema ./schema.pg --json
omnigraph query 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.
