🐛 Critical Bug Fixes (7 issues)

1. Session Manager - login_watch Storage Bug

File: lib/FB/Session/Manager.pm (line 118)

  • Issue: Stored table_id instead of login object in login_watch
  • Fix: Now correctly stores login object: $self->fb->login_watch->{$login_id} = $login
  • Impact: Prevents stale references and ensures proper login tracking

2. OmahaHiLo - Low Hand Scoring Algorithm

File: lib/FB/Poker/Strategy/Evaluator/OmahaHiLo.pm (lines 103-175)

  • Issue: Built low-hand scores in ascending order (A-2-3-4-5 → 12345) but normalizer expected descending (8-7-6-5-4 → 87654)
  • Fix: Reversed iteration order to build scores with highest rank first (54321 for wheel, 87654 for worst)
  • Impact: Correct hand evaluation for Omaha Hi-Lo split pots

3. Player ID Comparison

File: lib/FB/Poker.pm (lines 1383-1396)

  • Issue: Used non-existent $player->id method
  • Fix: Changed to $player->login->user->id with defensive checks
  • Impact: Prevents runtime errors when finding login objects for players

4. Session Grace Period Cleanup

File: lib/FB/Session/Manager.pm (grace_expired method)

  • Issue: Incomplete cleanup left stale entries in login_watch, channels, user_map
  • Fix: Added explicit cleanup of all data structures when grace period expires
  • Impact: Prevents memory leaks and stale connection references

5. ActionDecider RNG Independence

File: lib/FB/Poker/Strategy/ActionDecider.pm (lines 11-38)

  • Issue: Used global rand() for seed generation, affecting process-wide RNG
  • Fix: Changed to (time() ^ ($$ << 15)) for per-instance seed generation
  • Impact: Each house player now has independent, reproducible randomness

6. Channel Cleanup in Grace Expiry

File: lib/FB/Session/Manager.pm (lines 169-175)

  • Issue: Loop over channels lacked explicit removal of login entries
  • Fix: Added delete $channel->logins->{$login_id} with defensive checks
  • Impact: Proper cleanup of chat channel memberships

7. Test Constraint Handling

File: t/migrate.t (lines 255-285)

  • Issue: Database constraint tests caused test failures due to RaiseError => 1
  • Fix: Changed to RaiseError => 0 and check return values instead of exceptions
  • Impact: Tests now properly validate constraints without failing

Dependency Fixes

Added missing Perl modules to cpanfile and .github/workflows/test.yaml:

  • Tie::IxHash - Required by house player autoplay tests
  • SQL::Abstract - Required by FB::Db module
  • Crypt::Eksblowfish - Required by FB.pm for password hashing

Modern Deployment Infrastructure

Fixed vercel.json to properly route requests:

API routes go to the serverless function
Static files served from /public
All other routes serve index.html
Rewrote api/index.js as a proper serverless Express app (no server.listen())

Cleaned up package.json (removed unused deps, updated Node version)
…hich counts tests dynamically. Also removed plan tests => N from subtests.

migrate_integration.t - Added parse_database_url() helper function that converts postgresql://user:pass@host:port/db to proper DBI format dbi:Pg:dbname=db;host=host;port=port. Also uses done_testing().

test.yaml - Updated to explicitly install DBD::Pg and other required modules.
Verifies db directory exists before entering
Uses pushd/popd for proper directory handling
Checks both fb.schema and poker.schema exist
Finds sqlite3 in PATH or Strawberry location, fails with clear error if missing
Runs each sqlite3 command and checks ERRORLEVEL immediately after
Prints descriptive error messages for each failure case
Always popd before exiting on error
Tests:
- Fix migrate.t and migrate_integration.t to use done_testing() instead of fixed plan
- Add parse_database_url() helper to convert postgresql:// URLs to DBI format
- Add DBD::SQLite to CI workflow dependencies

Timer (FB::Compat::Timer):
- Fix recurring timer fallback to match EV::timer semantics (fire after $after, then every $repeat)
- Add cancel() method to properly remove both initial and recurring timers
- Use defined-or (//) instead of logical-or (||) to preserve explicit 0 values
- Fix remaining() to correctly compute time until next firing for recurring timers

Security:
- Restrict dev guest login to NODE_ENV=development only
- Return 403 in production when Facebook auth not configured
- Log warnings for blocked guest login attempts

- Check ERRORLEVEL after each sqlite3 command
- Add descriptive error messages for all failure cases

Vercel:
- Fix vercel.json routing for serverless deployment
- Rewrite api/index.js as proper serverless Express app
validate() - Removed bcrypt hashing, now only performs format validation
register() - Added _bcrypt_hash() call to hash password before storing via new_user()
login() - Now fetches user by username only, then verifies password using _bcrypt_verify() which compares plaintext against stored hash
Added helper methods _bcrypt_hash() and _bcrypt_verify() for proper bcrypt operations
Security (FB.pm):
- Remove bcrypt hashing from validate() - now only performs format checks
- Add _bcrypt_hash() helper with cost factor 12 for registration
- Add _bcrypt_verify() for secure password comparison in login()
- Hash passwords only once during register(), verify against stored hash in login()

Security (vercel/api/index.js):
- Validate FACEBOOK_APP_ID and FACEBOOK_APP_SECRET are non-empty before registering strategy
- Restrict guest login to NODE_ENV=development only
- Return 403 in production when Facebook auth not configured
- Add clear logging for auth configuration status

CI:
- Add DBD::SQLite to workflow dependencies for test compatibility
…re line since it already uses done_testing() at the end. The unique constraint error in migrate.t is expected behavior - it's testing that the database correctly rejects duplicate usernames using dies_ok.
…les)

Confirmed architecture: static HTML (public/index.html) + Express API (api/index.js)
No Next.js dependencies needed
FILEPATHS: Deleted vercel/pages/index.js, vercel/pages/_app.js
Previous State (Problem):

Used express-session with default MemoryStore
Sessions lost on serverless function restart
No JWT used anywhere
Users logged out randomly on Vercel
New State (Solution):

Replaced session-based auth with JWT tokens
Tokens stored in HTTP-only cookies (secure, not accessible via JS)
Stateless - works perfectly with Vercel serverless
No external store (Redis) needed
Changes Made:

vercel/package.json - Added jsonwebtoken dependency
vercel/api/index.js - Rewrote to use JWT instead of sessions
vercel/lib/server.js - Same JWT approach for local dev
vercel/.env.example - Added JWT_SECRET config
DEPLOYMENT_GUIDE.md - Updated env vars documentation
JWT Features Implemented:

7-day token expiration
HTTP-only cookies (XSS protection)
Secure flag in production (HTTPS only)
SameSite=lax (CSRF protection)
User payload: id, displayName, email, photo, isGuest
…ystem" }. This lets Vercel serve any existing static file directly before falling back to the catch-all route, which is more flexible and efficient.

Task 14: Final checkpoint and CI fixes
- Fixed test file library paths (mojopoker-1.1.1/lib -> lib)
- All 75 tests passing successfully across 12 test files
- Updated cpanfile with missing dependencies:
  * Algorithm::Combinatorics (for Omaha evaluator)
  * Mojo::IOLoop and Mojolicious (web framework)
  * Digest::SHA, JSON, MIME::Base64 (auth/serialization)
- Updated GitHub Actions workflow to use cpanm --installdeps
- Ensures CI environment matches local development setup

Test Results:
- 12 test files executed
- 75 tests passed
- 0 failures
- 2 skipped (PostgreSQL integration - requires DATABASE_URL)

All house player strategy module functionality is now complete and verified.
Created FB::Poker::Strategy::Evaluator::OmahaHiLo.pm

Implements proper Omaha Hi-Lo (Eight-or-Better) split-pot evaluation
Evaluates both high and low hands separately
Enforces 8-or-better qualification for low hands
Treats Aces as 1 for low evaluation
Ignores pairs, straights, and flushes for low hand ranking
Uses exactly 2 hole cards + 3 community cards (Omaha rule)
Returns combined strength considering both high and low potential
Updated FB.pm

Added use FB::Poker::Strategy::Evaluator::OmahaHiLo;
Changed line 121 from registering regular Omaha evaluator to OmahaHiLo evaluator:
$manager->register_evaluator('omahahilo', FB::Poker::Strategy::Evaluator::OmahaHiLo->new);
Created comprehensive test t/omaha_hilo_evaluator.t

Tests basic functionality
Tests high hand evaluation
Tests low hand qualification (8-or-better)
Tests that Aces count as low
Tests edge cases
Verifies exactly 2+3 card rule
Updated t/strategy_manager.t

Added OmahaHiLo evaluator registration test
Verifies correct evaluator retrieval for 'omahahilo' game class
Test Results:
✅ All 85 tests passing
✅ 13 test files executed successfully
✅ New OmahaHiLo evaluator properly integrated
Created FB::Poker::Strategy::Evaluator::OmahaHiLo with proper split-pot evaluation
Updated FB.pm to register the OmahaHiLo evaluator for 'omahahilo' game class
Added comprehensive tests for OmahaHiLo functionality
2. Removed Duplicate House Player Detection Logic
Changed in mojopoker-1.1.1/lib/FB/Poker.pm (lines ~1367-1370):
File: mojopoker-1.1.1/lib/FB/Poker.pm (line ~1427)
File: mojopoker-1.1.1/lib/FB/Poker/Strategy/ActionDecider.pm
Fixed the CI/CD test failure
…iLo.pm, lines 103-160)

Issue: The low-hand score was being built in ascending rank order (A-2-3-4-5 → 12345), but the normalizer expected descending order where the highest rank is the most significant digit (8-7-6-5-4 → 87654).

Fixes:

Reversed the iteration order when building the score to produce descending rank order
Updated the normalization constants: best low changed from 12345 to 54321 (representing 5-4-3-2-A)
Updated comments to clarify the scoring format
Fixed the test expectation to match the actual hand strength

Added Tie::IxHash to the dependency installation step in the GitHub Actions workflow.
Fixed Database Constraint Test Failures (t/migrate.t)
The cpanfile - so it's declared as a dependency
The workflow file - so it's explicitly installed during CI
feat: implement house player strategy module with automated decision-…
