# Implementation Report: Exchange Structured Output and Target Normalizer Readiness
Date: 2026-07-08
## Result
- **Status**: PASS.
- **Active spec**: `specs/435-exchange-structured-output-target-normalizer-readiness/`.
- **Branch**: `435-exchange-structured-output-target-normalizer-readiness`.
- **Requested branch label**: `feat/435-exchange-structured-output-target-normalizer-readiness`.
- **Branch-name exception**: recorded. Runtime/test implementation stayed on the current Spec Kit preparation branch because the active Spec 435 package was already untracked in this worktree; no branch switch was performed mid-dirty state.
- **HEAD at implementation start/end**: `a23131cd feat: add Exchange evidence capture adapter guard (#501)`.
- **Initial dirty state**: active Spec 435 package only.
- **Final dirty state**: active Spec 435 package plus intended Spec 435 runtime/test files.
- **Implementation/fix iterations**: 2 post-implementation findings fixed.
## Activated Skills and Gates
- `spec-kit-implementation-loop`: active implementation workflow.
- `pest-testing`: Pest 4 unit/feature coverage and validation.
- `tenantpilot-spec-readiness-gate`: active spec package readiness and close-out alignment.
- `tenantpilot-workspace-scope-safety`: no `tenant_id`, no scope/persistence drift, no provider-connection ownership drift.
- `tenantpilot-evidence-anchor-contract`: no evidence rows, no OperationRun-as-proof, no raw payload proof.
- `tenantpilot-provider-freshness-semantics`: runner success is not provider readiness or customer-safe evidence.
- `tenantpilot-operation-run-truth`: sanitized context only; no OperationRun lifecycle/start UX changes.
- Hard-gate stop conditions: none.
## Implementation Summary
- Added `ExchangePowerShellStructuredOutputEnvelope` as a safe in-memory envelope for structured Exchange runner output.
- Added target readiness dispatch through `ExchangePowerShellEvidenceNormalizer`.
- Added target-specific readiness normalizers for exactly:
- `transportRule`
- `remoteDomain`
- `inboundConnector`
- Added `ExchangePowerShellHashInputBuilder` and `ExchangePowerShellNormalizerReadiness` for deterministic in-memory hash previews and safe readiness summaries.
- Added focused Spec 435 unit and feature tests.
No evidence append, resource upsert, Graph/Exchange call, PowerShell execution, UI surface, job, listener, schedule, migration, `tenant_id`, customer output, restore, certification, compare/render promotion, or mini-platform was added.
## Prerequisite Proof
- Spec 434 implementation report records PASS and merge-ready after close-out hotfix.
- Spec 433 implementation report records PASS WITH CONDITIONS; the existing condition is outside this no-UI readiness slice.
- Spec 432 implementation report records PASS for production runner boundary, output guard, process executor abstraction, timeout/concurrency guards, and sanitized OperationRun context.
- Specs 430-434 were used as read-only context and were not edited.
## Structured Output Proof
- Accepted states:
- `structured_collection`
- `structured_empty_collection`
- Blocked states covered:
- malformed/scalar output
- warning-prefixed output
- binary/non-UTF8 output
- oversized output
- non-zero exit
- timeout
- Envelope safe summaries exclude raw stdout, raw stderr, transcripts, and credential/provider secret material.
- Empty collections stay distinguishable from malformed/failure states and create no durable proof.
## Target Matrix
| Type | Structured Output | Identity | Normalizer | Redaction | Hash Input | Ready for Spec 436? |
|---|---|---|---|---|---|---|
| `transportRule` | proven | stable `Guid`/source identity proven; display-only blocks | proven for state/mode, priority, conditions/actions/exceptions, volatile exclusions | sensitive conditions/actions redacted | deterministic, material/volatile/order tested | yes |
| `remoteDomain` | proven | source `Identity` proven for default/custom; display/domain-only/missing/duplicate/conflict block | proven for settings normalization | protected/sensitive remote-domain settings redacted | deterministic, includes target and normalizer metadata | yes |
| `inboundConnector` | proven | source `Identity` proven; missing/duplicate/conflict block | proven for routing settings | IPs, smart hosts, certificate names, comments, routing metadata redacted | deterministic, includes target and normalizer metadata | yes |
## No-Promotion Matrix
| Area | State |
|---|---|
| Evidence rows | No |
| Resource rows | No |
| Raw payload evidence | No |

## Product Surface Close-Out
- **Runtime UI files changed**: no.
- **UI impact**: N/A - no rendered UI surface changed.
- **Product Surface exceptions**: none.
- **Browser proof**: N/A - no rendered UI surface changed.
- **Human Product Sanity**: N/A - no product surface changed.
- **Visible complexity outcome**: neutral; backend-only readiness helpers.
- **No-legacy confirmation**: canonical addition only; no aliases, fallback readers, hidden routes, duplicate UI, or compatibility shim.
- **Completed-spec rewrite assertion**: completed Specs 430-434 were not rewritten.
- **Livewire v4 compliance**: unchanged.
- **Provider registration location**: unchanged under `apps/platform/bootstrap/providers.php`.
- **Global search posture**: unchanged; no resources were added or modified.
- **Destructive/high-impact action posture**: none; no UI action or runtime start surface added.
- **Asset strategy**: none; `filament:assets` not required for this slice.
- **Deployment impact**: no env vars, migrations, queues, scheduler, storage, assets, or Dokploy runtime behavior changes.
## Validation
- `cd apps/platform && ./vendor/bin/sail artisan test --filter=Spec435 --compact`
- Result: failed before completion with Symfony Process signal 9. Non-Docker fallback used per tasks.
- `cd apps/platform && php artisan test --filter=Spec435 --compact`
- Result: PASS, 28 tests / 167 assertions.
- `cd apps/platform && php artisan test --filter=Spec434 --compact`
- Result: PASS, 25 tests / 154 assertions.
- `cd apps/platform && php artisan test --filter=Spec433 --compact`
- Result: PASS, 48 tests / 211 assertions.
- `cd apps/platform && php artisan test --filter='Spec432|Spec431|Spec430' --compact`
- Result: PASS, 173 tests / 1357 assertions.
- `cd apps/platform && php artisan test --filter='Spec415|Spec417|Spec419|Spec420|Spec426|Spec427' --compact`
- Result: PASS, 202 tests / 2137 assertions, 8 existing PostgreSQL-specific skips. This filter also ran existing browser smoke tests for Specs 419 and 420, both passing.
- `cd apps/platform && php artisan test --filter='ProviderCapabilityRegistryTest|ProviderCapabilityEvaluationTest' --compact`
- Result: PASS, 7 tests / 30 assertions.
- `cd apps/platform && ./vendor/bin/pint --dirty --format agent`
- Result: fixed one test file initially; final rerun PASS.
- `git diff --check`
- Result: PASS. Note: active Spec 435 files are untracked, so this command does not inspect their content until staged/tracked; syntax checks, Pint, and tests covered the new file content.
- `git status --short`
- Result: intended Spec 435 runtime/test files plus active Spec 435 package only.
## Post-Implementation Analysis
Iteration 1 confirmed and fixed one in-scope finding:
- **Medium**: readiness previews preserved provider collection order for multi-item collections, while Spec 435 requires deterministic collection ordering. Fixed by sorting previews by stable identity value with identity/hash tie-breakers and added a regression test.
Iteration 2 confirmed and fixed one in-scope finding:
- **High**: structured output envelopes preserved forbidden secret-like provider fields in public `items` state even though `safeSummary()` excluded them. Fixed by recursively stripping forbidden secret, credential, token, authorization, cookie, transcript, and raw-output key families from accepted envelope items while preserving normalizer-relevant Exchange fields. Added regression coverage that asserts public envelope items no longer contain those fields.
Remaining in-scope findings: none.
Residual risks: none for Spec 435. Evidence append and customer/product promotion remain deferred to Spec 436 or later.

Prüfe, ob die Implementierung nach dem Agenten-Loop wirklich merge-ready ist.
Wichtig:
- Keine Implementierung.
- Keine Codeänderungen.
- Keine Scope-Erweiterung.
- Prüfe gegen spec.md, plan.md, tasks.md und constitution.md.
- Prüfe die geänderten Dateien, Tests, Browser-Smoke-Test-Ergebnis, RBAC, Workspace-/Tenant-Isolation, Auditability, UX und OperationRun-Semantik, soweit relevant.
- Benenne nur konkrete Findings mit Repo-Beleg.
- Gib am Ende eine klare Entscheidung: Merge-ready, merge-ready with notes, oder not merge-ready.
