Phase 35.5 — Preflight Diagnostic Contract Production Freeze

This release document details the formal milestone specifications, validation metrics, and operational guidelines for Phase 35.5 — Preflight Diagnostic Contract Production Freeze.

This release locks the foundational preflight contract and locks data flows across the printing pipeline.

PHASE 10/35 PREFLIGHT DIAGNOSTIC CONTRACT ALIGNMENT: COMPLETE
STATUS: PRODUCTION VALIDATED
RESULT: READY
BLOCKERS: NONE

1. Milestone Summary​

The Phase 35.5 Production Freeze marks the completion of our platform's diagnostic alignment objectives.

Every microservice, command-line utility, database schema, and dashboard component has been verified to conform to uniform data validation contracts. The production environment is validated as robust, stable, and ready to support customer-facing intake gates.

2. Production Validated Chain​

The preflight diagnostic pipeline successfully operates across our isolated microservice boundaries:

graph LR
    Engine[1. Preflight Engine] -->|Produces Truth| Service[2. Preflight Service]
    Service -->|Preserves Truth| Worker[3. Preflight Worker]
    Worker -->|Executes & Persists Truth| BFF[4. BFF/App]
    BFF -->|Displays Truth| CP[5. ControlPlane]
    CP -->|Governs Truth| Engine
  • Engine produces truth: Direct binary parsing analyzes layout and bleed structures without fabricating findings.
  • Service preserves truth: Registry databases store raw engine JSON traces without destructive semantic loss under validated outcome categories.
  • Worker executes and persists truth: Background task processors manage queues, upload file artifacts, and track execution.
  • BFF displays truth: Real-time dashboards render exact status badges and progress streams.
  • ControlPlane governs truth: Central administration panels check node environments and orchestrate sync sweeps.

3. Validated Analyze Job​

The diagnostic contract was verified using the following production analysis log:

  • Job Identifier (jobId): job_1779116602472_1d246
  • Operational Status: DEGRADED
  • Analysis Status: DEGRADED
  • Outcome Category: DEGRADED_ANALYSIS
  • Progress: 100
  • Analysis Integrity:
    • realExtraction: true (Inspected actual document geometry; not mocked)
    • degradedMode: true (Gracefully handled missing color tool configuration on the host)
  • Findings Count: 5
  • Artifact File: report.json (analysis_report)

4. Validated Autofix Job​

The automated repair pipeline was verified using the following vector correction trace:

  • Fix Identifier (fixId): fix_1779116602946
  • Source Analyze Job ID (sourceJobId): job_1779116602472_1d246
  • Execution Status: COMPLETED
  • Repairs Count: 4
  • Applied Repairs Count: 4 (All 4 layout anomalies successfully repaired)
  • Skipped Repairs Count: 0
  • Failed Repairs Count: 0
  • Repaired PDF Output: fixed.pdf (final_fixed_pdf)

5. Contract Rules Frozen​

All status transitions, error scopes, and parsing rules are frozen for Phase 35.5:

  • Graceful CLI Degradation: Missing optional command-line tools must not crash the container or cause FAILED_RUNTIME_ENVIRONMENT. The run must terminate as DEGRADED with progress: 100.
  • Truthful Telemetry: Under no circumstances may any component simulate or fabricate preflight findings.
  • Terminal Progress: Terminal diagnostic runs (including degraded runs) must report exactly 100 progress to prevent client-side infinite polling loops.

6. Auth Separation Frozen​

Security boundary protocols are locked across all inter-service transactions:

  • Isolation of Admin Token: The ControlPlane admin token (PPOS_CONTROL_TOKEN) is restricted to /api/admin/* and is strictly stripped from downstream service requests.
  • Inter-Service Auth: Downstream calls use dedicated, cryptographically signed PREFLIGHT_JWT bearer tokens with tenant scopes.

7. Artifact Contract Frozen​

Physical file storage, resolving priority, and error envelopes are locked:

  • Immutable Storage: Uploaded files (report.json, fixed.pdf, certified.pdf) are mapped to unique job IDs.
  • Resolution Rules: Logical aliases resolve to physical files using a strict priority order: fixed.pdf ➔ normalized.pdf ➔ certified.pdf.
  • Error Preservation: The ARTIFACT_NOT_FOUND error structure is strictly preserved, and must never be collapsed into generic server errors.

8. Known Watchpoints​

The following items are flagged for engineering observation during this freeze:

  • Coordinate Compaction: Documents containing massive coordinates can cause database transport lag. Coordinate compaction heuristics are scheduled for evaluation.
  • Sync Batches: Large-scale regional synchronization queries can strain memory buffers. Batching constraints must be monitored.
  • SSE Resilience: Browser-side Server-Sent Events (SSE) must have retry safeguards if internet connections drop.

9. Next Phase: Phase 36 — Production Order Intake & File Governance​

note

DEVELOPMENT BLUEPRINT: The upcoming Phase 36 modules are under design and are not part of the active frozen production deployment. Phase 36 starts after the Phase 35.5 production freeze.

With the stabilization of our diagnostic contracts complete, the platform is positioned to execute Phase 36: Production Order Intake & File Governance. Phase 36 will bind marketplace selected offers directly to final PDF uploads, compute order readiness using preflight status, gate invoicing, and prepare standardized metadata handoffs for printhouses.

10. Last Production Validation Telemetry​

The last active inter-service execution has been verified in production and logged under the following records:
