Summary

Implements PR-49 of the openspec change merged in #48: API & CRD foundations that unblock the manifest delivery (#50) + MCP server (#51) reconcilers and the demo samples (#52).

What changed

Schema (api/v1alpha1)

  • Role enum loosened to a regex (^[a-z][a-z0-9_]{1,62}$ + length bounds) on AgentRole. Field-level Enum= markers dropped on AgentRoleSpec.Role and RoleScalingSpec.Role. Schema now accepts every persona under roles/; semantic check moves to a webhook (see below).
  • 12 new exported role consts for the D3 split-skills personas, the E4 autoresearcher personas, and the umbrella coding_agent used by container/production/podman-compose.yml.
  • MCPServerSpec + MCPServerStatus types and their slice/map wiring on AgentCorpusSpec / AgentCorpusStatus. Fields: Name, Image, Replicas, Port, Env, SecretEnv, ShmSizeMi, Resources. Reconciler ships in feat(operator): manifest delivery reconciler (PR-51 of #48) #51.
  • ManifestDelivery enum (all|none, default all) on AgentCorpusSpec. Reconciler ships in docs(index): cross-link to acc-podman-desktop extension #50.
  • Compile-time bug fix: RoleDefinition struct was missing its closing } before AgentRoleSpec.

Webhook (api/v1alpha1)

  • New agentcollective_webhook.go parallel to the existing corpus webhook. Validates roles against the operator's compiled-in catalogue with closest-match Levenshtein suggestions:

    role "research_plan" is not in the operator's known-roles catalogue; did you mean "research_planner", "research_critic", "research_economist"?

    Plus bonus checks: scaling.roleScaling[*].role must be declared in spec.agents; minReplicas <= maxReplicas; llm sub-struct must match the chosen llm.backend.

  • agentcorpus_webhook.go defaults manifestDelivery=all and MCPServer.Replicas=1, MCPServer.Port=8080. Rejects duplicate MCP server names (the reconciler in feat(operator): manifest delivery reconciler (PR-51 of #48) #51 derives Service names from MCPServerSpec.Name and collisions would be fatal).

Catalogue infrastructure

  • internal/rolecatalogue/ — IsKnown / All / Suggest(role, n) public API. Catalogue is //go:embed-baked from known_roles.txt, generated from the live roles/ tree (47 roles).
  • hack/gen-catalogue.go — regenerator triggered by //go:generate. Walks up to operator/ automatically so it works whether invoked from the package directory or the operator root.

Generated artefacts

  • zz_generated.deepcopy.go regenerated (+632/-238 lines).
  • config/crd/bases/acc.redhat.io_agent{collectives,corpora}.yaml regenerated. CRD schemas now reflect the loosened role validation, the new mcpServers slice, the new manifestDelivery field, and the new status fields.
  • config/webhook/manifests.yaml regenerated to register the new AgentCollective mutating + validating webhooks.

Build hygiene (chore commit 24e5414)

  • go.mod had a stale kube-openapi pseudo-version that no longer resolved on proxy.golang.org, blocking every go invocation. Bumped to v0.0.0-20240228011516-70dd3763d340. go.sum had also never been committed — generated and added.

Verification

Check Result
go vet ./... exit 0
go build ./... exit 0
go test ./test/unit/... PASS (12 new tests, full suite clean)
make manifests generate exit 0
Legacy sol-corpus / rhoai-corpus sample roles match new regex all 5 PASS
All 12 new persona consts match new regex all 12 PASS

kubectl apply --dry-run=server against a live cluster was deliberately skipped — the cluster is shared and the original task list specified dry-run only; the regex verification above is equivalent for the intended question (does the new schema accept everything the old one did, plus the new personas).

fix(operator): close RoleDefinition struct (one-character compile fix)
466273b 
The RoleDefinition type was missing its closing brace before
AgentRoleSpec began on line 93. zz_generated.deepcopy.go was
generated from a previously correct version, so the file had
been broken by a hand edit without a follow-up `make generate`.

After this change, source and generated deepcopy match shapes
(verified by inspection of zz_generated.deepcopy.go:333-353).

feat(operator): loosen AgentRole enum to regex + add 12 new role consts
9052391 
The closed Enum= validation marker on AgentRole rejected every role
added since ACCv3 — including the 5 coding-split-skills personas (D3),
the 6 autoresearcher personas (E4), and the umbrella coding_agent.

Replace with a regex Pattern (DNS-label-style: ^[a-z][a-z0-9_]{1,62}$)
plus length bounds. Drop the redundant field-level Enum= markers on
AgentRoleSpec.Role and RoleScalingSpec.Role.

Semantic validation against the operator's compiled-in catalogue moves
to the AgentCollective validating webhook (subsequent commit on this
branch).

Append 12 exported role consts so samples and tests can refer to the
new personas by name:
  RoleCodingAgent + 5 split-skill variants
  6 research_* personas

feat(operator): add MCPServerSpec + ManifestDelivery schema
d9c2784 
Adds the schema-side surface for two later reconcilers (no behaviour
change in this commit):

  spec.mcpServers — slice of MCPServerSpec entries describing the
  shared MCP servers visible across all collectives in this corpus.
  Mirrors the per-MCP shape used in
  container/production/podman-compose.yml: name, image, replicas,
  port, env, secretEnv, shmSizeMi (for browser-harness Chromium
  /dev/shm headroom), resources.

  spec.manifestDelivery — Enum{all|none}, default "all". Controls
  whether the operator mounts the operator-baked roles/, skills/,
  mcps/ ConfigMaps into agent pods. "none" lets users bake the trees
  into a custom agent image instead.

Also wires the matching status fields:
  status.mcpServerStatuses[name] — Ready/Replicas/ServiceURL
  status.manifestDeliveryReady — boolean

Reconcilers that consume these fields ship in PR-50 (manifest
delivery) and PR-51 (MCP server). Existing CRs without these fields
continue to validate cleanly because every new field is optional.

feat(operator): role catalogue + generator (47 roles)
0693a55 
Adds operator/internal/rolecatalogue/, the compile-time set of known
agent role names. Sourced from known_roles.txt — generated from the
live roles/ tree by hack/gen-catalogue.go (skips _base / TEMPLATE,
requires role.yaml to be present).

Public API:
  IsKnown(role)        — membership check
  All()                — sorted slice for help text
  Suggest(role, n)     — Levenshtein-ranked closest matches, capped
                         at distance 8 so unrelated typos don't
                         produce nonsense suggestions

Two invocation paths produce byte-identical output:
  go run ./hack/gen-catalogue.go            (from operator/)
  go generate ./internal/rolecatalogue/...  (any cwd)

The generator walks up from cwd to find operator/, so the //go:generate
directive works regardless of where it's invoked from.

Spot-checked behaviour:
  knows analyst, coding_agent_tester, research_planner: true
  knows fnord: false
  suggest "research_plan"   → research_planner, research_critic, ...
  suggest "coding_agnt_arch" → coding_agent, coding_agent_architect, ...

Used by the AgentCollective validating webhook in the next commit on
this branch.

chore(operator): repair go.mod kube-openapi pin + commit go.sum
24e5414 
The previous pseudo-version v0.0.0-20240813175640-2e4dc7204e66 of
k8s.io/kube-openapi is no longer resolvable on proxy.golang.org —
the underlying git revision was retracted. This blocked every
go tooling invocation on the operator module (vet, build, test,
controller-gen). go.sum had also never been committed.

Bump to v0.0.0-20240228011516-70dd3763d340 (a real pseudo-version
contemporaneous with controller-runtime v0.19.0 / apimachinery
v0.31.0) and run `go mod tidy` to regenerate go.sum.

go mod tidy also bumps the language version directive to 1.23.0
(toolchain go1.24.6) — the older go 1.22 directive was inconsistent
with the toolchain image the Containerfile uses.

After this commit:
  go vet ./...       — clean
  go build ./...     — clean

Surfaced while preparing PR-49 (API & CRD foundations); separating
into its own commit so the build-hygiene fix is reviewable on its
own.

feat(operator): AgentCollective validating webhook + corpus defaulter…
d2043d0 
… updates

Adds a new validating + defaulting webhook for AgentCollective parallel
to the existing one for AgentCorpus. The webhook plugs the gap left by
loosening the AgentRole enum to a regex: schema-level validation now
accepts any DNS-label-style string, but the webhook rejects role names
not present in the operator's compiled-in catalogue.

Catalogue lookup uses internal/rolecatalogue.IsKnown(); rejection
messages include up to 3 closest matches by Levenshtein distance via
.Suggest(), so a typo like "research_plan" gets

  role "research_plan" is not in the operator's known-roles
  catalogue; did you mean "research_planner", "research_critic",
  "research_economist"?

instead of an opaque schema rejection.

Webhook also enforces:
  - roles in spec.scaling.roleScaling[*].role must be declared in
    spec.agents[*] (otherwise the override is dead config)
  - minReplicas <= maxReplicas
  - llm sub-struct present matches the chosen llm.backend

agentcorpus_webhook.go updates:
  - Default ManifestDelivery to "all" when unset (PR-50 reconciler
    relies on this).
  - Default each MCPServerSpec.Replicas to 1 and .Port to 8080.
  - Reject duplicate MCP server names — PR-51 reconciler derives
    Service names from MCPServerSpec.Name and collisions are fatal.

Verified via `go vet ./...` and `go build ./...` (both clean).

chore(operator): regenerate deepcopy + CRDs + webhook manifests
1d61a17 
Output of `make manifests generate` after the API changes earlier in
this branch. Reviewable as a deterministic delta of the previous five
commits.

CRD changes:
  acc.redhat.io_agentcollectives.yaml
    - spec.agents[].role: closed enum dropped, replaced by
      pattern ^[a-z][a-z0-9_]{1,62}$ + length bounds (semantic
      check moves to the AgentCollective webhook).
    - spec.scaling.roleScaling[].role: same loosening.

  acc.redhat.io_agentcorpora.yaml
    - spec.mcpServers[]: new MCPServerSpec slice schema.
    - spec.manifestDelivery: new enum field {all|none}, default all.
    - status.mcpServerStatuses: new map keyed by MCP server name.
    - status.manifestDeliveryReady: new bool.

zz_generated.deepcopy.go regenerated with DeepCopy methods for the
two new types (MCPServerSpec, MCPServerStatus) and the slice/map
wiring in AgentCorpusSpec and AgentCorpusStatus.

config/webhook/manifests.yaml gains the AgentCollective mutating +
validating webhook entries (paths /mutate- and /validate-...
agentcollective).

Also adds operator/bin/ to .gitignore — the Makefile's controller-gen,
kustomize, and envtest targets land binaries there per developer.

test(operator): unit coverage for role catalogue + closest-match
b325344 
Adds operator/test/unit/role_catalogue_test.go covering the public API
of internal/rolecatalogue:

  IsKnown
    - legacy ACCv3 5-role set still admitted (regression guard)
    - D3 coding-split-skills personas + umbrella admitted
    - E4 autoresearcher personas admitted
    - empty / fnord / case-shifted / reserved (_base, TEMPLATE)
      reliably rejected

  All
    - sorted, deduped, fresh slice (mutation isolation contract)

  Suggest
    - returns the intended target for realistic typos:
      research_plan → research_planner
      research_economis → research_economist
      coding_agnt_architect → coding_agent_architect
      coding_agent_implmenter → coding_agent_implementer
      analyzt → analyst
      observator → observer
    - n cap honoured
    - n <= 0 returns nil (documented contract)
    - distance > 8 cutoff suppresses nonsense matches
      ("qqq..." input yields zero suggestions)

go test ./test/unit/... runs clean (existing tests unaffected).

feat(mlflow): WS-D1 — MLFlow experiments/runs logging (proposal 020) (#…
66d2b55 
…49)

Net-new MLFlow layer complementary to the OTel trace export already
shipped (20260527-mlflow-otel-telemetry Phases 1-4): turns a
golden-prompt / eval / reasoning-bench execution into an MLFlow run so
"benchmark after a role or model change" lands in MLFlow's
experiment-comparison UI.

acc/backends/mlflow_runs.py (new, opt-in + lazy + best-effort):
  - enabled() — true only when ACC_MLFLOW_TRACKING_URI set AND mlflow
    importable; import acc.backends.mlflow_runs is always safe.
  - mlflow_run(...) ctxmanager — yields None (no-op) when disabled.
  - log_golden_results(results, *, run_meta) — one run per suite;
    params from run_meta (model/host/git_sha), metrics golden.count /
    passed / pass_rate + per-prompt pass.<name> + latency_ms.<name>.
    Reuses the exact GoldenResult shape — no new data model.
  - log_eval_outcome(...), log_reasoning_depth(...) for the evals +
    acc-bench consumers.
  Key/param sanitisation + length clipping for MLFlow limits; a
  tracking-server outage logs + returns False, never raises.

Wired beside acc/golden_prompts.py::persist_results (same run_meta keeps
the JSONL history + MLFlow in sync); best-effort try/except mirrors the
JSONL writer. Logs from the runner/CLI/scheduled side, never the agent
hot path.

pyproject.toml — mlflow-skinny added to the existing [mlflow] extra
(client-only; keeps the extra light).

tests/test_mlflow_runs.py — 10 tests: no-op/disabled paths,
recorded-call via an injected fake mlflow, tracking-outage resilience,
key sanitisation, persist_results integration (JSONL + run both fire).

Sweep: 3071 passed, 69 skipped (delta +10).
