# Contents

- `crates/gobstopper-core/` holds the normalized transcript model, the `Edit` IR, the `Strategy` trait, all built-in strategies, and the `compaction-events-v1` telemetry schema. No I/O beyond event-log append.

- `crates/gobstopper-adapters/` holds session discovery, the Codex and Claude Code JSONL dialects (parse and in-place rewrite), the `verify` resume-validity checker, and the `vault` content-addressed snapshot store.

- `crates/gobstopper-cli/` holds the `gobstopper` binary and layered config/preset resolution.

- `docs/design.md` is the architecture and research record; `docs/roadmap.md` is the phased plan; `docs/oompa-contract.md` is the oompa integration contract.

# Guidelines

- Strategies are pure: transcript in, plan out. Execution lives in adapters.

- Rewrites replace payload content in place; provider record order and linkage (`parentUuid`, `ordinal`) are never disturbed.

- Never emit transcript content (prompts, tool output, paths beyond what the provider record carries) into stdout, logs, or digests unless the user asked for that field.

- `detect`/`policy-check`/`plan --json`/`verify --json`/`vault --json` are the stable machine surfaces; keep their fields additive-only.

- Every mutating path (`apply`, `watch`) snapshots into the vault before writing and emits a `compaction-events-v1` record after; telemetry failures are non-fatal, snapshot failures abort the edit.

- The `auto` strategy must always prefer provider delegation for live sessions; file surgery is for idle transcripts.

- Keep dependency count small; prefer `std` + `serde_json` over new crates.
