Viktor Barzin c7c7047f1c [ci skip] Flatten module wrappers into stack roots 
Remove the module "xxx" { source = "./module" } indirection layer
from all 66 service stacks. Resources are now defined directly in
each stack's main.tf instead of through a wrapper module.

- Merge module/main.tf contents into stack main.tf
- Apply variable replacements (var.tier -> local.tiers.X, renamed vars)
- Fix shared module paths (one fewer ../ at each level)
- Move extra files/dirs (factory/, chart_values, subdirs) to stack root
- Update state files to strip module.<name>. prefix
- Update CLAUDE.md to reflect flat structure

Verified: terragrunt plan shows 0 add, 0 destroy across all stacks.

Phase 1 Plan 1: Scraper Validation Summary

URL validation pipeline with 18 video/player markers filtering scraped links before store merge, configurable via SCRAPER_VALIDATE_TIMEOUT

Performance

  • Duration: 3 min
  • Started: 2026-02-17T20:49:16Z
  • Completed: 2026-02-17T20:51:54Z
  • Tasks: 3
  • Files modified: 4

Accomplishments

  • Created validate.go with 18 video/player markers covering HTML5, HLS, DASH, and 10+ player libraries
  • Wired validateLinks into scrape() pipeline between URL extraction and store merge
  • Added SCRAPER_VALIDATE_TIMEOUT env var (default 10s) following existing config patterns
  • Added 25 unit tests (10 positive + 4 negative marker tests, 6 positive + 5 negative content type tests)

Task Commits

Each task was committed atomically:

  1. Task 1: Create validate.go with video marker detection - adeb478 (feat)
  2. Task 2: Wire validation into scraper pipeline and add config - 22d29db (feat)
  3. Task 3: Add unit tests for validation functions - 6c5cc02 (test)

Files Created/Modified

  • internal/scraper/validate.go - URL validation with video marker detection (validateLinks, hasVideoContent, containsVideoMarkers, isDirectVideoContentType)
  • internal/scraper/validate_test.go - Table-driven unit tests for marker detection and content type checks (25 cases)
  • internal/scraper/scraper.go - Added validateTimeout field and validateLinks call in scrape()
  • main.go - Added SCRAPER_VALIDATE_TIMEOUT env var read (default 10s)

Decisions Made

  • Used string matching (not DOM parsing) for video detection -- DOM parsing reserved for Phase 4 link extraction
  • Set 2MB body read limit to prevent memory issues on large streaming pages
  • Limited redirects to 3 to avoid infinite redirect chains on sketchy stream sites
  • Validation runs sequentially (not concurrent) to avoid overwhelming target sites

Deviations from Plan

None - plan executed exactly as written.

Issues Encountered

None.

User Setup Required

None - no external service configuration required.

Next Phase Readiness

  • Validation pipeline is integrated and tested, ready for health check layer (Phase 2)
  • The validateLinks function provides the filtering foundation that health checks will build upon
  • No blockers or concerns

Self-Check: PASSED
