From c80c66c2e5b6c04967a5064de9c55c14c69627f6 Mon Sep 17 00:00:00 2001 From: Trey t Date: Fri, 27 Feb 2026 22:29:14 -0600 Subject: [PATCH] Codebase hardening: 102 fixes across 35+ files Deep audit identified 106 findings; 102 fixed, 4 deferred. Covers 8 areas: - Settings & deploy: env-gated DEBUG/SECRET_KEY, HTTPS headers, gunicorn, celery worker - Auth (registered_user): password write_only, request.data fixes, transaction safety, proper HTTP status codes - Workout app: IDOR protection, get_object_or_404, prefetch_related N+1 fixes, transaction.atomic - Video/scripts: path traversal sanitization, HLS trigger guard, auth on cache wipe - Models (exercise/equipment/muscle/superset): null-safe __str__, stable IDs, prefetch support - Generator views: helper for registered_user lookup, logger.exception, bulk_update, transaction wrapping - Generator core (rules/selector/generator): push-pull ratio, type affinity normalization, modality checks, side-pair exact match, word-boundary regex, equipment cache clearing - Generator services (plan_builder/analyzer/normalizer): transaction.atomic, muscle cache, bulk_update, glutes classification fix Co-Authored-By: Claude Opus 4.6 --- .env.example | 25 + docker-compose.yml | 6 + equipment/models.py | 2 +- equipment/views.py | 9 +- exercise/models.py | 3 +- exercise/serializers.py | 23 +- exercise/views.py | 12 +- .../commands/populate_exercise_fields.py | 18 +- .../commands/recalculate_workout_times.py | 8 +- generator/rules_engine.py | 126 +++- generator/serializers.py | 6 +- generator/services/exercise_selector.py | 253 +++++-- generator/services/muscle_normalizer.py | 16 +- generator/services/plan_builder.py | 139 ++-- generator/services/workout_analyzer.py | 33 +- .../services/workout_generation/__init__.py | 6 + .../workout_generation/entry_rules.py | 39 ++ .../services/workout_generation/focus.py | 41 ++ .../services/workout_generation/modality.py | 53 ++ .../workout_generation/pattern_planning.py | 26 + .../services/workout_generation/recovery.py | 14 + .../services/workout_generation/scaling.py | 31 + .../workout_generation/section_builders.py | 68 ++ generator/services/workout_generator.py | 635 ++++++++++-------- generator/tests/test_exercise_family_dedup.py | 63 ++ .../tests/test_exercise_similarity_dedup.py | 142 ++++ generator/tests/test_modality_guardrails.py | 103 +++ generator/tests/test_movement_enforcement.py | 106 +++ .../tests/test_rebalance_replacement_guard.py | 60 ++ generator/tests/test_rules_engine.py | 83 +++ generator/tests/test_side_pair_integrity.py | 203 ++++++ generator/tests/test_warmup_selector.py | 102 ++- .../tests/test_workout_generation_modules.py | 136 ++++ generator/views.py | 374 ++++++----- hardening-report.md | 482 +++++++++++++ muscle/models.py | 2 +- muscle/views.py | 7 +- registered_user/admin.py | 6 +- registered_user/models.py | 2 +- registered_user/serializers.py | 35 +- registered_user/views.py | 49 +- scripts/views.py | 28 +- superset/helpers.py | 25 +- superset/models.py | 14 +- superset/serializers.py | 20 +- supervisord.conf | 15 +- video/models.py | 42 +- video/serializers.py | 6 +- video/tasks.py | 7 +- video/views.py | 41 +- werkout-frontend/next.config.mjs | 28 +- werkout_api/settings.py | 201 +++--- workout/helpers.py | 12 +- workout/models.py | 9 +- workout/serializers.py | 56 +- workout/tasks.py | 169 +++-- workout/urls.py | 2 +- workout/views.py | 190 ++++-- 58 files changed, 3363 insertions(+), 1049 deletions(-) create mode 100644 .env.example create mode 100644 generator/services/workout_generation/__init__.py create mode 100644 generator/services/workout_generation/entry_rules.py create mode 100644 generator/services/workout_generation/focus.py create mode 100644 generator/services/workout_generation/modality.py create mode 100644 generator/services/workout_generation/pattern_planning.py create mode 100644 generator/services/workout_generation/recovery.py create mode 100644 generator/services/workout_generation/scaling.py create mode 100644 generator/services/workout_generation/section_builders.py create mode 100644 generator/tests/test_exercise_family_dedup.py create mode 100644 generator/tests/test_exercise_similarity_dedup.py create mode 100644 generator/tests/test_modality_guardrails.py create mode 100644 generator/tests/test_rebalance_replacement_guard.py create mode 100644 generator/tests/test_side_pair_integrity.py create mode 100644 generator/tests/test_workout_generation_modules.py create mode 100644 hardening-report.md diff --git a/.env.example b/.env.example new file mode 100644 index 0000000..61e063e --- /dev/null +++ b/.env.example @@ -0,0 +1,25 @@ +# Django core +DEBUG=false +SECRET_KEY=your-secret-key-here + +# Allowed hosts (comma-separated) +ALLOWED_HOSTS=yourdomain.com + +# CORS (comma-separated origins) +CORS_ALLOWED_ORIGINS=https://yourdomain.com + +# Database (used when DATABASE_URL is not set) +DB_NAME=werkout +DB_USER=werkout +DB_PASSWORD=your-db-password +DB_HOST=db +DB_PORT=5432 + +# Database URL (overrides individual DB_* vars when set) +DATABASE_URL=postgres://user:password@db:5432/werkout + +# Redis +REDIS_URL=redis://redis:6379 + +# HTTPS redirect (set to false if behind a reverse proxy that handles SSL) +SECURE_SSL_REDIRECT=true diff --git a/docker-compose.yml b/docker-compose.yml index d60a406..eb65cac 100644 --- a/docker-compose.yml +++ b/docker-compose.yml @@ -25,6 +25,10 @@ services: environment: -

Enables offline brute-force. +- Source: Security, API, Cross-cutting + +**5. registered_user/views.py:83-90** | update_registered_user uses request.POST — JSON requests wipe user data +- What: `request.POST.get(...)` only works for form-encoded data.

Push splits get assigned random types. + +**4. workout_generator.py:2070** | Modality check counts exercise capability, not actual assignment +- What: Checks `ex.is_duration` (capability flag) not whether the entry was actually given duration. +- Impact: False modality calculations for dual-modality exercises. + +**5. workout_generator.py:1404** | Diversify type count wrong on replacement +- What: Doesn't subtract from the removed type count when replacing, only adds to candidate count. +- Impact: Valid replacements rejected.

Retry with different exercises creates ghost entries. +- Impact: Later days in the week have artificially smaller exercise pools. + +**8. entry_rules.py:19** | Volume floor can violate workout type rep ranges +- What: With `min_volume=12` and `rounds=1`, forces 12 reps. Strength (3-6 rep range) gets 12 reps. +- Impact: Strength workouts get inflated reps contradicting their character. + +**9. rules_engine.py:441** | Push/pull counting double-counts dual-pattern exercises +- What: Exercise with `'upper push, upper pull'` counted in BOTH push AND pull totals. +- Impact: Inaccurate push:pull ratio calculations. + +**10. exercise_selector.py:631** | No-equipment path restricts to bodyweight only (contradicts docs) +- What: MEMORY.md says "no equipment set = all exercises available."
