[BUG] claude_code.commit.count, claude_code.lines_of_code.count and other metrics not emitted via OTLP

What's Wrong?

Version: 2.1.136
Platform: macOS (darwin 25.4.0)
Client: VS Code extension (also tested briefly via CLI — same result)
OTel setup: OTLP HTTP/JSON exporter → working pipeline (confirmed via cost/token metrics flowing correctly)

What's working:
claude_code.cost.usage (USD)
claude_code.token.usage

Not emitted (never appear in AMP despite working pipeline):
mmit.count
claude_code.lines_of_code.count
claude_code.code_edit_tool.decision
claude_code.session.count
claude_code.pull_request.count
claude_code.active_time.total
Confirmed working: cost/token metrics flow end-to-end proving the OTLP pipeline is functional.

Question: Are these metrics intended to be emitted via OTLP in the current release? If so, what conditions trigger them? If not, is there a target version?

CLAUDE_CODE_ENABLE_TELEMETRY=1, OTEL_METRICS_EXPORTER=otlp, export interval 5s.

What Should Happen?

All metrics listed in the documentation should be emitted via OTLP on the configured export interval (5s). Specifically, lines_of_code.count should increment when Claude Code edits files via its Edit tool, and commit.count should increment when Claude Code performs a git commit via its Bash tool.

Steps to Reproduce

Steps to Reproduce:

1. Enable telemetry: CLAUDE_CODE_ENABLE_TELEMETRY=1, OTEL_METRICS_EXPORTER=otlp, OTEL_METRIC_EXPORT_INTERVAL=5000
2. Point OTEL_EXPORTER_OTLP_METRICS_ENDPOINT to a working OTLP receiver
3. Open Claude Code (VS Code extension or CLI)
4. Ask Claude Code to edit a file using its Edit tool
5. Ask Claude Code to commit the change via git
6. Wait 10+ seconds for the export interval
7. Check metrics backend: only claude_code.cost.usage and claude_code.token.usage appear
