+Implemented, reviewed, merged, and validated.
+
+Summary:
+- Added reusable `crates/session-analytics` library with `analyze_session(path) -> SessionReport`.
+- Added thin product CLI `yoi session analyze <SESSION_JSONL_PATH> --json` that delegates to the library.
+- Implemented tolerant streaming JSONL parsing with bounded malformed/unknown-entry diagnostics.
+- Report covers tool usage counts, calls per turn, failed tool counts, repeated reads with mutation/context-lifecycle observations, edit/write churn, `replace_all`, large edit/result observations, saved/truncated Bash outputs, and compaction/prune/context correlations.
+- Default report avoids raw user input, raw tool arguments, raw file contents, raw session snippets, and raw tool output content.
+- Tests use synthetic/minimal fixtures rather than private local sessions.
+- No Worker pruning/compaction, Pod protocol/history/session writer, TUI dashboard, prompt auto-fixer, or LLM summarization behavior was changed.
+
+Implementation:
+- Coder commit: `c1809b3 feat: add session analytics tooling`
+- Reviewer approved with no blocking findings.
+- Merge commit: `0d2a6a7 merge: add session analytics tooling`
+
+Validation after merge:
+- `cargo test -p session-analytics`
+- `cargo test -p yoi session_cli`
+- `cargo test -p yoi parse_session_analyze_uses_session_mode`
+- `cargo fmt --check`
+- `git diff --check`
+- `cargo run -q -p yoi -- ticket doctor`
+- `cargo check --workspace`
+- `nix build .#yoi`

 - Repeated-read and Bash-file-inspection diagnostics are correctly framed as observations/correlations rather than automatic blame.
 - The new top-level `session` subcommand reserves that literal bare token; explicit `--pod session` remains the escape hatch for a Pod named `session`.
