Progress Log: Polling Count Rename (007)

Task Description

Refactored codebase to rename sample_count parameter to poll_count across all modules. The original name "sample_count" was misleading, suggesting statistical sampling, when the actual behavior is GPIO register polling to detect cosmic rays. This refactoring improves semantic clarity for developers and aligns terminology with embedded systems standards.

Scope: 8 files affected, ~25 occurrences renamed

  • include/config.h: Macro definition
  • include/runtime_config.h: Struct field, function declarations
  • src/runtime_config.cpp: Implementation, status output
  • src/cosmic_detector.cpp: Detector loop variables (2 modes)
  • src/text_command_handler.cpp: Command name, dispatch table, error messages, help text
  • CLAUDE.md: Documentation

Outcome

✅ COMPLETED SUCCESSFULLY

Execution Timeline

  1. Phase 1 (Core Implementation): 5 tasks completed
  2. Updated macro, struct, function declarations/implementations
  3. Updated detector loops and serial command handler

  4. Committed: e152f58 (36 insertions, 36 deletions)

  5. Phase 2 (Documentation): 3 tasks completed

  6. Updated CLAUDE.md command references and module descriptions
  7. docs/api.md verification (no changes needed - placeholder file)

  8. Committed: 40af970 (6 insertions, 6 deletions)

  9. Phase 3 (Validation): 3 tasks verified

  10. task dev:build: ✅ SUCCESS (23.0% Flash, 7.3% RAM)
  11. task prod:build: ✅ SUCCESS (22.7% Flash, 6.9% RAM)
  12. No compilation errors, warnings, or regressions
  13. Memory usage unchanged (pure refactoring)

Build Results

  • Development Profile: SUCCESS (0.84s)
  • Production Profile: SUCCESS (2.96s)
  • RAM Usage: 6.9-7.3% (unchanged)
  • Flash Usage: 22.7-23.0% (unchanged)

Critical File Verification

  • ✅ config.h: DETECT_POLL_COUNT macro renamed
  • ✅ runtime_config.h: struct field and function signatures updated
  • ✅ text_command_handler.cpp: dispatch table, alias table, help text updated
  • ✅ CLAUDE.md: all command examples and configuration sections updated

Learnings

  1. Mechanical Refactoring Patterns: Pure renaming changes require coordination across:
  2. Macro definitions (config layer)
  3. Type definitions and interfaces (header files)
  4. Implementation details and initialization
  5. Runtime dispatch tables and command handlers

  6. Documentation and user-facing interfaces

  7. Build System Reliability: Multiple build profiles (dev/prod) compiled without issues, confirming:

  8. Header file changes properly propagated
  9. Function signature changes correctly resolved at link time

  10. No version-specific incompatibilities introduced

  11. Documentation Preservation: Historical documentation (release notes, progress logs) appropriately preserved references to old naming as context, while current documentation (CLAUDE.md) updated to new terminology.

Next Steps

  1. Create release notes for v1.6.7 documenting breaking change
  2. Consider backward compatibility alias (optional) if needed by clients
  3. Update any client code or integration tests using old command name
  4. Tag release and notify users of protocol change
