fix: review-driven hardening of pos ai hf/server + llamacpp provider 
Adversarial review of the AI tools (commits 387f23f/0856b25) found 2
BLOCKING + 5 REQUIRED defects; all fixed:

- pos-ai-hf --include/--exclude: bash-case glob filtering (array-safe,
  no jq regex interpolation, composes gguf->filename->include->exclude)
- pos-ai-server: ExecStart rebuilt as single-line properly-quoted command
  (systemd_quote for executable + model path; systemd-analyze verify rc=0)
- --branch/--revision aliased (last wins), dead BRANCH variable removed
- parallel download drains all jobs: per-pid wait, honest
  'X of Y files, N failed' summary, rc=1 on partial failure, no .hf-meta
  for half-downloaded models, EXIT-trap temp cleanup
- detect_llama_version guarded; validate_requested_flags errors on
  unsupported explicit flags with version-aware message
- pos ai hf cache [status|clear]: real implementation, fail-closed confirm
- new bin/pos-ai-llamacpp thin forwarder + llamacpp shorthand in bin/pos-ai
  (pos ai llamacpp <subcmd> = pos ai --provider llamacpp <subcmd>)
- docs synced: bin/pos-ai usage(), DOC/POS.md AI_PROVIDER row, howto/ai.md
  (adapter list, --provider backends, shorthand, providers table); gen
  regenerated (tree/dispatch/completions)

Verified: bash -n all bin/pos*; make gen idempotent; make check green;
make lint 0 FAIL, 0 WARN. Reviewer acceptance: APPROVE_WITH_NOTES
(0 REQUIRED). Audit deliverables + agent reports included for context.

Detailed Audit of POS AI Tools vs. Underlying Applications

1. pos ai hf - Audit Table

Category Current Implementation Upstream Hugging Face CLI Missing Incorrect Fix
Repository Discovery Basic search hf list, hf info info command - Add pos ai hf info <repo>
File Listing --list flag hf files files command - Add pos ai hf files <repo>
Model Information Basic metadata Detailed model info No detailed info - Add model details display
Repository Files Limited listing hf files with sizes No file listing - Add file listing command
Downloading Basic download hf download with include/exclude No pattern filtering - Add --include/--exclude
Revisions --branch --revision support No tag/commit support - Add revision support
Cache Management No cache commands hf cache No cache commands - Add pos ai hf cache
Authentication HF_TOKEN only Credential helpers, more tokens Limited auth - Add enhanced auth
Progress Reporting Basic progress Detailed metrics Limited info - Add progress details
File Pattern Matching Basic file matching Wildcards, patterns No pattern support - Add pattern matching
Multi-Shard Support Limited Full sharded support No sharded model support - Add sharded model support
Error Handling Basic errors Detailed error messages Limited context - Improve error reporting

2. pos ai server - Audit Table

Category Current Implementation Upstream llama.cpp Missing Incorrect Fix
Model Loading Basic model selection --model with validation - - Enhance model validation
GPU Offloading Auto-detect --n-gpu-layers, multi-GPU No detailed GPU control - Add GPU layer control
Memory Context Basic context --ctx-size, KV cache Limited memory options - Add memory controls
Performance Tuning Basic params Batch sizes, threads, ubatch No tuning - Add performance options
Sampling Controls Basic Temperature, top-k, top-p No sampling options - Add sampling parameters
Advanced Features No advanced JSON/schema, tool calling No advanced features - Add advanced options
Server Configuration Basic Health, metrics, concurrency Limited server options - Add server options
Version Detection No version --version support No version awareness - Add version detection
Process Management Basic Graceful shutdown, monitoring Limited process control - Add process monitoring
Logging Basic Logging controls No log options - Add logging controls

3. Detailed Missing Features

For pos ai hf:

Missing Repository Information:

  • No info command to show repository details
  • No way to see model architecture or parameters
  • No commit history or version details

Missing File Operations:

  • No files command to list repository contents
  • No file pattern matching or filtering
  • No file size information in listings

Missing Advanced Downloading:

  • No --include/--exclude patterns
  • No revision/tag support
  • No cache management commands

Missing Authentication:

  • No credential helper support
  • No token validation
  • No multi-auth method support

For pos ai server:

Missing GPU Configuration:

  • No --n-gpu-layers support
  • No tensor splitting (--tensor-split)
  • No multi-GPU configuration
  • No GPU device selection

Missing Memory Management:

  • No --ctx-size control
  • No KV cache configuration
  • No memory mapping (--mmap) or locking (--mlock)

Missing Performance Options:

  • No batch size control (--batch-size)
  • No ubatch size (--ubatch-size)
  • No continuous batching options

Missing Sampling Controls:

  • No temperature control
  • No top-k, top-p options
  • No repetition penalty
  • No JSON/schema support

Missing Server Features:

  • No health endpoint configuration
  • No metrics endpoint support
  • No concurrency controls
  • No graceful shutdown handling

Missing Version Awareness:

  • No version detection capability
  • No feature compatibility checking
  • No version-specific option support

4. Implementation Priority

Critical (Must Have):

  1. Add info and files commands for pos ai hf
  2. Add GPU control for pos ai server
  3. Add version detection
  4. Add proper error handling

High Priority:

  1. Add --include/--exclude patterns
  2. Add revision support
  3. Add memory context control
  4. Add performance tuning options

Medium Priority:

  1. Add cache management
  2. Add enhanced authentication
  3. Add advanced sampling
  4. Add advanced server configuration

Low Priority:

  1. Add progress metrics
  2. Add logging controls
  3. Add process monitoring
  4. Add integration with POS ecosystem

5. Technical Requirements

For pos ai hf:

  • Enhanced parsing for new flags
  • Integration with Hugging Face API
  • Cache management system
  • Better file pattern matching
  • Improved error reporting

For pos ai server:

  • Enhanced parameter parsing
  • Version detection system
  • GPU configuration module
  • Memory management controls
  • Process management system
  • Configuration validation

6. Compatibility Considerations

Backward Compatibility:

  • All existing commands must work unchanged
  • All existing options must work unchanged
  • Default behavior must be preserved
  • Configuration file compatibility maintained

Breaking Changes:

  • None planned
  • All enhancements are additive
  • No existing functionality removed

7. Testing Requirements

pos ai hf Testing:

  • Model download functionality
  • File pattern matching
  • Revision handling
  • Cache operations
  • Authentication testing

pos ai server Testing:

  • GPU configuration validation
  • Memory parameter testing
  • Performance tuning options
  • Server startup/shutdown
  • Version compatibility testing

This audit identifies the comprehensive gap between the current POS tools and the capabilities of the underlying Hugging Face CLI and llama.cpp server. The implementation plan will address all these gaps systematically.
