+# Provider conformance
+
+This harness keeps the services → agents → workflows lifecycle honest across the
+supported AI providers. It runs the same end-to-end scenarios against each
+configured provider and treats missing provider keys as an explicit skip, so the
+suite is safe for local development, forks, and scheduled CI.
+
+## What it exercises
+
+`go run ./internal/harness/provider-conformance` fans out over the provider-facing
+agent test and the harnesses in `internal/harness`:
+
+- `agent` — provider tool-call conformance through `agent.Ask`, including run metadata propagation.
+- `universe` — service discovery plus agent tool calls over the real runtime.
+- `agent-flow` — a workflow event that drives an agent to call services.
+- `plan-delegate` — plan persistence plus agent-to-agent delegation and service
+  calls.
+- `a2a-stream-fallback` — A2A `message/stream` through the gateway, including
+  fallback from unsupported provider streaming to the tool-calling `Ask` path while
+  preserving run metadata.
+
+The command also emits the registered provider capability matrix so the run shows
+which providers advertise model, image, video, and streaming support. Console output
+and summary artifacts label each harness with the phase it is proving (for example,
+model call + tool call, workflow event + tool call, or streaming fallback + tool
+call), so provider failures identify the failed lifecycle phase instead of only the
+provider name.
+
+## Local usage
+
+Run the deterministic path with no secrets:
+
+```sh
+go run ./internal/harness/provider-conformance -providers mock
+```
+
+Run every live provider that has a key in the environment:
+
+```sh
+go run ./internal/harness/provider-conformance \
+  -summary-json provider-conformance-summary.json \
+  -summary-markdown provider-conformance-summary.md \
+  -capabilities-markdown provider-capabilities.md
+```
+
+Provider keys are read from `MICRO_AI_API_KEY` or the provider-specific variable:
+
+| Provider | Secret / environment variable |
+| --- | --- |
+| Anthropic | `ANTHROPIC_API_KEY` |
+| OpenAI | `OPENAI_API_KEY` |
+| Gemini | `GEMINI_API_KEY` |
+| Groq | `GROQ_API_KEY` |
+| MiniMax | `MINIMAX_API_KEY` |
+| Mistral | `MISTRAL_API_KEY` |
+| Together | `TOGETHER_API_KEY` |
+| AtlasCloud | `ATLASCLOUD_API_KEY` |
+
+Use `-require-configured` when you want a selected provider without a key to fail
+instead of skip. This is useful for manually checking that a required provider
+secret is actually wired into CI before relying on that provider as covered:
+
+```sh
+go run ./internal/harness/provider-conformance \
+  -providers anthropic,openai \
+  -require-configured
+```
+
+## Scheduled CI behavior
+
+The `Harness (E2E)` workflow runs on pushes and pull requests with deterministic
+mock LLMs, including `provider-conformance -providers mock`. On the hourly
+schedule and manual dispatch it also runs the live provider conformance job. A
+manual dispatch can narrow `providers` or `harnesses`, and can set
+`require_configured=true` to fail fast when an expected repository secret is
+missing; scheduled runs keep the safe default and report missing keys as skips.
+That job:
+
+1. runs the same `agent`, `universe`, `agent-flow`, `plan-delegate`, and `a2a-stream-fallback` harness list,
+2. reads the provider keys from repository secrets,
+3. skips providers whose secrets are absent,
+4. fails when any configured provider fails a harness, and
+5. uploads JSON and Markdown coverage artifacts for the run.
+
+The job also appends the Markdown summary and capability matrix to the GitHub
+Actions step summary, making configured, skipped, and failed provider coverage
+visible without downloading artifacts.
+
+## Adding a provider
+
+To bring a new provider into scheduled conformance:
+
+1. register its `ai` provider implementation and capability metadata,
+2. add the provider name and key variable to `providerEnv` in `main.go`,
+3. import the provider package in `main.go`,
+4. pass the matching repository secret through `.github/workflows/harness.yml`,
+   and
+5. run `go run ./internal/harness/provider-conformance -providers <name> \
+   -require-configured` with a live key before opening the change.

+// Universe harness — a mini end-to-end world, spun up and shut down.
+//
+// It boots a small but real go-micro system in one process and drives a
+// realistic scenario across all the moving parts:
+//
+//   - four real services (inventory, payment, orders, notify) over RPC;
+//   - a DURABLE FLOW "checkout" with ordered, checkpointed steps that
+//     reserves, charges, confirms, then hands off to an agent;
+//   - a CRASH + RESUME: the payment dependency fails on first contact, the
+//     run is checkpointed at that step, and on resume it continues without
+//     re-running the steps that already completed;
+//   - an AGENT "concierge" with guardrails and a tool-execution wrapper,
+//     reached by the flow over RPC, that sends the welcome notification;
+//   - SCOPED STATE: the flow's runs and the agent's history land in their
+//     own store tables.
+//
+// Everything is real — registry, RPC, broker, store, the flow engine, the
+// agent loop. Only the LLM is mocked, so it runs free and deterministically
+// in CI. Pass -provider anthropic (with a key) to run it against a live
+// model. It exits non-zero if any assertion fails, so it doubles as an
+// end-to-end test.
+//
+// Run:
+//
+//	go run ./internal/harness/universe

+# 0→hero CI harness
+
+This directory owns the no-secret reference scenario for the Go Micro
+services → agents → workflows lifecycle. It is intentionally small and
+scripted so CI can run it on every push without external services or model keys.
+
+`run.sh` verifies the complete first-agent 0→hero contract together:
+
+1. **Scaffold** — the maintained `micro new` 0→1 contract still creates
+   runnable services from a clean workspace.
+2. **First agent** — `micro agent demo`, `micro examples`, `micro agent preflight`,
+   `micro run`, `micro chat`, and `micro inspect agent <name>` remain available
+   as the documented first-agent walkthrough path.
+3. **Run** — `micro run` remains available as the local development entry point.
+4. **Chat** — `micro chat` remains available as the interactive agent entry point.
+5. **Inspect/debugging** — `micro inspect agent <name>`, `micro agent history <name>`,
+   and `micro inspect flow <name>` remain available as the local run-history
+   inspection step. The no-secret debugging smoke seeds durable agent run history
+   and memory, then runs the documented inspect/history commands without provider
+   credentials; `micro flow runs` preserves durable workflow history inspection.
+6. **Deploy** — `micro deploy --dry-run <target>` remains available as the
+   deployment-boundary checkpoint. The dry run resolves configured deploy targets
+   and services and prints the remote build/copy/systemd/health plan without
+   building binaries, opening SSH connections, running `rsync`, or touching
+   remote infrastructure.
+
+After the CLI boundary smoke checks, the script runs the deterministic harnesses
+that boot real services, agents, workflows, store-backed run history, plan/delegate,
+and A2A with only the LLM mocked.
+
+## Local and CI entry points
+
+The default GitHub harness workflow runs this script on every push and pull
+request after the install smoke check and 0→1 scaffold contract. Developers can
+verify the first-agent on-ramp links and CLI command-output parity with
+`make docs-wayfinding` whenever README or website first-agent breadcrumbs,
+`micro agent demo`, `micro examples`, or `micro zero-to-hero` change. That
+check is provider-free and fails if documented command names, guide links, or
+maintained no-secret example paths drift from the CLI outputs. To verify the
+installed first-run CLI seam alone, use `make install-smoke`; to run just the documented
+agent debugging quickcheck with
+`go test ./internal/harness/zero-to-hero-ci -run TestNoSecretFirstAgentDebuggingSmoke -count=1`,
+or run the same no-secret contract locally with:
+
+```sh
+make harness
+```
+
+That target intentionally exercises the first-agent docs wayfinding guard, the
+install script smoke path, both 0→1 scaffold variants, the 0→hero scenario, the
+event-driven agent-flow harness, and mock provider conformance, so
+the public scaffold → run/chat → inspect → deploy lifecycle stays executable
+outside CI as well. Live provider checks remain separate and gated by configured
+API keys (`make provider-conformance` or the scheduled/manual CI job).
