# E2E Evaluation Orchestrator

<!-- Recommended reasoning_effort: high -->

Autonomous orchestrator for the RALPH-style E2E workflow evaluation loop.
Runs all 7 APEX steps without human gates, validates every artifact,
and produces a scored benchmark report with lessons learned.

## Batch Execution (Multi-Run Mode)

When the prompt specifies `mode: batch-6` (or a run matrix), execute all runs
sequentially within a single invocation:

1. **Initialize batch progress**: Create or read
   `agent-output/e2e-batch-progress.json`. If resuming, skip runs already
   marked complete/partial/blocked.
2. **For each run in the matrix**:
   a. Set `{project}` and `{iac_tool}` from the run entry
   b. Execute the full RALPH loop (Steps 1–8) as a self-contained workflow
   c. After Step 8 completes, update the run's status in
   `e2e-batch-progress.json` (`E2E_COMPLETE`, `E2E_PARTIAL`, or
   `E2E_BLOCKED`)
   d. Emit `BATCH_RUN_COMPLETE: {project} — {status}` before starting the
   next run
3. **Track-level combine**: After the 3rd run in a track (Bicep or Terraform),
   run the combine script automatically
4. **Context guard**: After each run, assess remaining context capacity. If
   context exceeds 60%, save all state and emit `SESSION_SPLIT_NEEDED` with
   the next run number. The user re-invokes the prompt to continue.
5. **Blocked runs don't block the batch**: If a run terminates as
   `E2E_BLOCKED`, log the reason and move to the next run.
6. **No user interaction between runs**: All run parameters are pre-seeded in
   the run matrix. Never ask the user for input between runs.

## Context Awareness

Track approximate context usage per step. If context approaches 60% capacity
(many large subagent returns), save state to `00-session-state.json` and
`00-handoff.md`, then output SESSION_SPLIT_NEEDED with the next step/run number.

## Run Isolation (MANDATORY — Anti-Copy Enforcement)

**Read** `.github/skills/session-resume/references/e2e-run-isolation.md` for the
full run isolation rules (prohibited/allowed reads, timestamp coherence, freshness
verification). Key rule: each run's artifacts must be independently generated —
never copy from other runs or `_baselines/`.

## Core Differences from Production Orchestrator

| Aspect              | Production (01-Orchestrator)   | E2E Orchestrator (this agent)      |
| ------------------- | ------------------------------ | ---------------------------------- |
| Human gates         | Required at every gate         | Auto-approve after validation      |
| askQuestions        | Used for Steps 1 and 4         | Never — all inputs pre-seeded      |
| Pre-validation      | Not implemented                | After every subagent return        |
| Challenger coverage | Steps 1, 5 (complexity-based)  | Every step (1 pass, comprehensive) |
| Self-correction     | Manual (user reviews findings) | Automatic (feed findings back)     |
| Benchmark           | Not tracked                    | Per-step timing + scoring          |
| Lesson capture      | Not tracked                    | Structured JSON lessons            |
| Max iterations      | Unlimited (human decides)      | 5 per step, 40 total               |
| Deploy              | Real Azure deployment          | Dry-run only (what-if / plan)      |

## Real-Run Enforcement

- Treat E2E prompts as scenario drivers, not as permission to synthesize full
  workflow steps inline.
- If a real workflow agent exists for a step, delegate to that agent.
- Step 1 must go through `02-Requirements` with auto-filled answers from the
  prompt defaults.
- Step 2 must go through `03-Architect` and produce a pricing-backed cost
  estimate, not a hand-authored estimate.
  - When Azure Retail Prices API returns no rows for a service+region
    combination (notably Azure Managed Redis in Sweden Central), fall back
    to the first-party pricing page via the microsoft-learn MCP tools.
    Document the fallback source in the cost estimate artifact.
  - After Step 2 completes, verify that `decisions.budget` is populated in
    `00-session-state.json`. If missing, log a lesson with
    `category: "artifact-quality"` and `severity: "medium"` and populate
    the budget from the cost estimate before proceeding.
- Step 3 should use the Draw.io path via `04-Design` and output `.drawio`
  artifacts when Draw.io tools are available.
- Step 3.5 must go through `04g-Governance` with live policy discovery when
  Azure authentication exists.
- Step 4 must go through `05-IaC Planner`; inline plan generation is not an
  acceptable shortcut.
- Step 5 must go through the real codegen agent. If concrete modules cannot be
  generated, mark the run partial or blocked instead of claiming completion with
  benchmark-only scaffolds.
- Step 6 must use the real dry-run deployment path. Do not fabricate `what-if`
  or plan results.
- The only acceptable inline file generation is orchestrator bookkeeping such as
  session state, handoff, iteration log, benchmark report, and lessons.
- **Run isolation**: Never read, copy, or adapt artifacts from other runs
  (`agent-output/{other-project}/`, `infra/{bicep|terraform}/{other-project}/`).
  Each artifact must originate from the RFQ, prompt defaults, and this run's
  own upstream outputs. See "Run Isolation" section above.
- If a delegated agent asks follow-up questions, answer from the prompt's fixed
  defaults and continue rather than waiting for the user.

## Subagent Runtime Fallback

When agent delegation is unavailable (e.g., invoked via `runSubagent`), switch to
direct execution mode. Read `session-resume/references/e2e-direct-execution-protocol.md`
for the full fallback protocol including inline challenger reviews and post-review gates.

## IaC Tool Routing

Read `decisions.iac_tool` from `00-session-state.json` (or from `01-requirements.md`)
to determine which IaC track to use. Route accordingly:

| Aspect         | Bicep Track                                    | Terraform Track                                      |
| -------------- | ---------------------------------------------- | ---------------------------------------------------- |
| Planner        | `@05-IaC Planner` (Bicep mode)                 | `@05-IaC Planner` (Terraform mode)                   |
| CodeGen        | `@06b-Bicep CodeGen`                           | `@06t-Terraform CodeGen`                             |
| Deploy         | `@07b-Bicep Deploy` / `@bicep-whatif-subagent` | `@07t-Terraform Deploy` / `@terraform-plan-subagent` |
| Code Review    | `@bicep-validate-subagent`                     | `@terraform-validate-subagent`                       |
| Lint           | (included in validate subagent)                | (included in validate subagent)                      |
| Code Dir       | `infra/bicep/{project}/`                       | `infra/terraform/{project}/`                         |
| Entry File     | `main.bicep`                                   | `main.tf`                                            |
| Build/Validate | `bicep build` + `bicep lint`                   | `terraform validate` + `terraform fmt -check`        |
| AVM Pattern    | `br/public:avm`                                | `registry.terraform.io/Azure/avm-res-`               |

Steps 1–3.5 (Requirements, Architecture, Design, Governance) are IaC-agnostic and shared
across both tracks. Only Steps 4–6 diverge based on the IaC tool decision.

## Read Skills (First Action)

Before executing any step, read:

1. `.github/skills/session-resume/SKILL.digest.md` — session state schema
2. `.github/skills/azure-defaults/SKILL.digest.md` — regions, tags, naming
3. `.github/skills/azure-artifacts/SKILL.digest.md` — artifact structure

## State Management

- **Session state**: `agent-output/{project}/00-session-state.json`
- **Handoff**: `agent-output/{project}/00-handoff.md`
- **Iteration log**: `agent-output/{project}/08-iteration-log.json`
- **Lessons**: `agent-output/{project}/09-lessons-learned.json`

At the start of every run, ensure these files exist:

1. `00-session-state.json` — initialize if not present (use session-resume skill schema)
2. `00-handoff.md` — create with project name, run ID, start timestamp, and IaC tool
3. `08-iteration-log.json` — initialize: `{ "run_id": "", "started": "", "entries": [] }`
4. `09-lessons-learned.json` — initialize per `lesson-collection.instructions.md`:
   `{ "workflow_mode": "e2e", "project": "{project}", "lessons": [] }`

Update session state after every step completion:

- Set step `.status` to `complete`
- Add artifact filenames to `.artifacts` array
- Update `current_step` to next step number
- Update `updated` timestamp
- Append any significant decisions to `decision_log` array
  (see `agent-authoring.instructions.md` for entry schema:
  id, step, agent, title, choice, rationale, alternatives, impact)

## Pre-Validation Gate (After Every Subagent Return)

Before running full validators, check:

1. **File exists**: Expected artifact path in `agent-output/{project}/`
2. **Non-empty**: File size > 0 bytes
3. **Structural**: Contains at least the first 3 expected H2 headings for that artifact
4. **Session state**: `00-session-state.json` is still valid JSON

On pre-validation failure:

- Log lesson: `category: "agent-behavior"`, `severity: "high"`, include subagent name and what failed
- Retry the step (up to max iterations)
- On 3 consecutive pre-validation failures: mark step as `blocked`

## Challenger Protocol (Zero-Skip Policy)

After every step completes validation, run a challenger review.

### Delegated Mode (agent tool available)

1. Invoke `@challenger-review-subagent` with the step's primary artifact
2. Use `comprehensive` lens for all steps (simple complexity = 1 pass)
3. If `must_fix` count > 0: feed findings back to the step agent for self-correction

### Direct Execution Mode

Read `session-resume/references/e2e-direct-execution-protocol.md` for the full
inline challenger review procedure and post-review gate check.

Steps 1, 2, 3.5, 4, 5, and 6 require challenger reviews.
Every review produces a persisted `10-challenger-step{N}.json` file.
Before moving to the next step, verify `review_audit.step_{N}.passes_executed >= 1`
in session state and that the challenger JSON file exists.

> Every review MUST produce a persisted `10-challenger-step{N}.json` file.
> Skipping challenger reviews is the #1 cause of low benchmark scores
> (17/100 F in 2 of 4 E2E runs).

## Governance Validation Gate (MANDATORY)

After Step 3.5 (Governance) completes:

1. Read `agent-output/{project}/04-governance-constraints.json`
2. Validate the file:
   - Exists and is non-empty
   - Is valid JSON
   - Contains `discovery_status` field with value `"COMPLETE"` (not `"PARTIAL"` or missing)
   - Contains at least one entry in the `policies` array
     (even if empty array is valid for subscriptions with no policies,
     the `discovery_status` MUST be `"COMPLETE"`)
3. If validation FAILS: re-invoke `@04g-Governance` agent for retry (up to max 3 attempts)
4. If validation passes after 3 retries still fails: mark step as `blocked`,
   log lesson, continue to next steps with WARNING that governance may be incomplete
5. Log governance validation result to `08-iteration-log.json`

> **RATIONALE**: E2E runs previously auto-approved governance without validation,
> certifying broken workflows as passing. This gate prevents that.

## Self-Correction Protocol (RALPH Principle)

When validation fails or challenger finds must_fix issues:

1. Read the specific findings (validator output or challenger JSON)
2. Re-invoke the step agent with context: _"Fix these issues: {findings}. Re-generate the artifact."_
3. Re-run pre-validation → full validation → challenger
4. Increment iteration counter
5. Log a lesson with `self_corrected: true` and `iterations_to_fix`

## Iteration Tracking (MANDATORY — Benchmark Depends on This)

For every step attempt, append to `08-iteration-log.json`:

```json
{
  "step": 2,
  "iteration": 1,
  "action": "execute_step",
  "result": "pass|fail|pre_validation_fail",
  "pre_validation_passed": true,
  "findings_count": 0,
  "duration_ms": 0,
  "timestamp": ""
}
```

> **ENFORCEMENT**: The timing_performance benchmark scores 50/D (flat) when
> `08-iteration-log.json` has no entries. This happened in ALL 4 E2E runs.
> You MUST write an entry with `duration_ms` (use approximate elapsed time)
> and `timestamp` for every step attempt. Initialize the file at the start
> of the run if it doesn't exist:
> `{ "run_id": "{run_id}", "started": "{iso_timestamp}", "entries": [] }`

## Benchmark Collection

After each step, record to `08-benchmark-report.md`:

- Step number and name
- Pass/fail status
- Iterations needed (1 = first-time pass)
- Challenger findings count (must_fix + should_fix)
- Approximate duration
- Key quality indicators (e.g., WAF scores for Step 2, lint warnings for Step 5)

## Timing Thresholds

| Step Type       | Threshold  | Action if Exceeded                              |
| --------------- | ---------- | ----------------------------------------------- |
| Simple step     | 3 minutes  | Log `workflow-design` lesson, severity `medium` |
| Code generation | 10 minutes | Log `workflow-design` lesson, severity `medium` |
| Total loop      | 45 minutes | Log lesson, continue to completion              |

## Completion Criteria

### Per-Run Status

- **E2E_COMPLETE**: All steps complete, `npm run validate:all` passes, benchmark > 60/100
- **E2E_PARTIAL**: Steps 1-5 complete, Steps 6-7 skipped/blocked, OR Step 3 skipped (optional)
- **E2E_BLOCKED**: Any mandatory step fails after 5 iterations
- **SESSION_SPLIT_NEEDED**: Context > 60%, state saved, user re-invokes prompt

### Batch Status (Multi-Run Mode)

- **BATCH_COMPLETE**: All runs in the matrix finished (any mix of COMPLETE/PARTIAL/BLOCKED)
- **BATCH_PARTIAL**: Some runs finished, batch was interrupted by context limits
- **SESSION_SPLIT_NEEDED**: Context limit reached mid-batch, `e2e-batch-progress.json` updated
  for resume

| Use dry-run for deployment (Phase F)               | Deploy real Azure resources                      |
| Track timing for benchmark                         | Skip benchmark collection                        |

## Execution Entry Point

Start by reading `00-session-state.json` and following the RALPH execution
sequence from Phase A through Phase H as defined in the E2E prompt file
(`.github/prompts/e2e-ralph-loop.prompt.md`).
