Delete legacy code that used old company_ai_usage/job_seeker_ai_usage tables:
- Remove has_active_ai_pack() - old AI_PACK pricing package check
- Remove check_and_increment_usage() - legacy daily quota tracking
- Remove BASE_AI_LIMIT, get_ai_limit_for_package constants/functions
- Remove legacy queries from ai_auto_apply() and ai_usage_status()
- Update auto_apply.rs to use user_ai_subscriptions.daily_actions_used
instead of job_seeker_ai_usage table
- Inline apply_scheduled_downgrades() and expire_trials() in cron tasks
to remove dependency on users crate internal modules
The new system uses user_ai_subscriptions with:
- daily_actions_used / daily_credits_used counters
- monthly_credits_total / monthly_credits_used
- purchased_credits_total / purchased_credits_used
All AI billing now flows through the wallet/ledger system with
LiteLLM integration (Tasks 1-10).
- Add AI plans, credits, model routing, LiteLLM client, and orchestrator services
- Add AI management endpoints, auto-apply/auto-request handlers, and log endpoints
- Add cron jobs for daily action reset and monthly credit reset
- Add AI credit purchase flow in payments service
- Add ai_credit_packages migration with seed data
- Update Dockerfile build tooling across services
- Add get_llm_base_url() and get_llm_model() helper functions
- Update call_ollama_inline to route to LiteLLM when LLM_PROVIDER=litellm
- Add auto-apply cron task for background job matching
- Auto-apply matches job seekers to new jobs based on skills
- Generate cover letters via LiteLLM for each application
- companies: user.name in email and contact queries
- customers: user.name in email
- job_seekers: u.name in company user query
- cron tasks (jobs/leads/requirements): use u.name instead of u.full_name
- contracts/profession_shared: u.name for customer_name fields
- Update leads service to use 'leads' table
- Update extension models to use user_role_profile_id
- Update ProfessionalRepository to work with new schema
- Create TracecoinWalletRepository for wallet operations
- Update all handlers to use new model fields
- Rename Application fields (job_seeker_id -> applicant_user_id)
- Update cron tasks for new schema
- Fix compilation errors across all services
Added openssl-libs-static and OPENSSL_STATIC=1 environment variable
to fix reqwest/native-tls compilation errors with musl target.
Changes:
- Install openssl-libs-static in builder
- Set OPENSSL_STATIC=1 and OPENSSL_DIR=/usr
- Ensures OpenSSL is statically linked for all services
Switched from Debian to Alpine Linux for significant improvements:
- Image size: ~5MB vs ~100MB (95% smaller)
- Security: Minimal attack surface, no glibc vulnerabilities
- Static linking: No glibc version issues ever again
- Uses rust:alpine builder with x86_64-unknown-linux-musl target
- Static binaries with RUSTFLAGS='-C target-feature=+crt-static'
Fixes the GLIBC_2.38 error permanently by avoiding glibc entirely.
Fixed glibc version mismatch between rust:latest builder (glibc 2.38+)
and debian:bookworm-slim runtime (glibc 2.36). This was causing:
- ./companies: /lib/x86_64-linux-gnu/libc.so.6: version GLIBC_2.38 not found
- ./payments: /lib/x86_64-linux-gnu/libc.so.6: version GLIBC_2.38 not found
- Similar errors for users service
Updated all 19 service Dockerfiles + Dockerfile.template to use
debian:trixie-slim which includes glibc 2.38+.
