Major Release - Security, API, and Secret Hardening Migration

Summary

• Migrated app transport to same-origin Pages API proxy routes with Firebase bearer-token verification at the edge boundary.
• Hardened internal worker authentication paths and upstream proxy header handling across user, data, audit, image, and PDF request surfaces.
• Expanded and standardized secret deployment flow (workers and Pages), including stronger config/secret separation and deployment-script validation.
• Simplified and stabilized worker-domain handling by removing custom-domain injection into worker Wrangler configs while preserving secret-based routing contracts.
• Applied targeted stabilization fixes during migration (header auth semantics, deletion reliability, 500-path corrections, and type generation refresh).

Detailed Changes

API Boundary Migration and Authentication Hardening

• Refactored frontend/backend API interactions to route through Pages /api/* proxy endpoints instead of direct worker-domain browser calls.
• Added and refined Firebase token retrieval/lookup/verification behavior for API-bound requests.
• Completed phased migration of higher-risk operations and service routes with auth-scoped forwarding behavior.
• Corrected auth-response handling to improve proxy/worker interoperability after migration.

Secret Management and Deployment Hardening

• Added Pages secret deployment workflow and integrated required secret contracts for proxy routing and worker auth.
• Updated deploy/config scripts to reduce legacy fallback behavior and tighten configuration consistency.
• Strengthened script guidance around generated config, validate-only checks, and deployment ordering.
• Kept worker domains as secret/config inputs for routing and fallbacks, not as worker Wrangler custom-domain replacement values.

Worker Auth and Route Surface Stabilization

• Removed custom worker route replacement paths from deployment flow where they were causing drift and complexity.
• Iterated worker Access/auth changes, then stabilized with targeted reverts to keep the secure proxy-secret baseline intact.
• Regenerated worker runtime types and aligned migration-era auth/header behavior across workers.

Reliability, Operations, and Supporting Refinements

• Fixed deletion-operation reliability and upstream error handling in migration call paths.
• Addressed API-path failures (including 500-class regressions) discovered during migration rollout.
• Updated compatibility metadata and preserved release-surface stability through final script and auth cleanups.
• Included in-window UX/supporting updates (for example single-case export progress visibility) alongside security/API migration work.

Key Fix Summary

Category	Change	Impact
API Security Boundary	Same-origin /api/* proxy migration with Firebase edge verification	Reduces direct worker exposure and centralizes auth enforcement at the Pages boundary
Worker Auth Hardening	Header/auth semantics refined across worker proxy paths	Improves internal service trust enforcement and reduces auth drift/failures
Secret and Config Hardening	Pages+worker secret deployment and stricter script validation	Makes deployment safer, more repeatable, and less error-prone
Route/Domain Stabilization	Removed worker custom-domain replacement in Wrangler updates	Prevents config churn while preserving secret-driven upstream routing
Migration Reliability	Targeted fixes and controlled reverts during rollout	Maintains secure, stable behavior while converging on hardened architecture

Technical Implementation Details

API and Edge Verification Layer

• Migrated service calls in phased sequence to proxy-backed API transport.
• Hardened Firebase token handling and request validation for auth-gated API routes.
• Corrected auth header handling to align Pages proxy and worker enforcement behavior.

Deployment and Secret Layer

• Added/iterated Pages secret deployment script behavior and required secret inventory.
• Updated deploy-config/deploy-worker-secrets flows for stricter config hygiene and reduced legacy fallback behavior.
• Stabilized worker-domain treatment as secret routing inputs rather than Wrangler replacement targets.

Worker and Runtime Layer

• Applied worker auth/header fixes across migrated services.
• Regenerated worker runtime types and aligned migration outputs with current contracts.
• Used targeted reverts to preserve secure baseline behavior when intermediate migration paths introduced excess complexity.

Release Statistics

• Commit Range: v3.3.0..v4.0.0
• Commits Included: 37 (non-merge)
• Build Status: Succeeded (npm run build)
• Typecheck Status: Succeeded (npm run typecheck)
• Lint Status: Succeeded with warnings (npm run lint: 0 errors, 2 warnings)

Closing Note

v4.0.0 marks a major architectural hardening milestone: API transport now centers on authenticated edge proxy boundaries, worker auth and secrets are more rigorously managed, and deployment scripts are aligned to a safer secret/config migration model for production operations.
