From 735ac72e3e46845d4464a95f1f1d2713cd1b1927 Mon Sep 17 00:00:00 2001 From: Will Washburn Date: Wed, 6 May 2026 08:16:08 -0400 Subject: [PATCH 1/3] relayburn-cli: clap scaffold + render helpers (#248 part a) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Replaces the eprintln!/exit-1 stub in `crates/relayburn-cli/src/main.rs` with a proper clap v4 derive root, eight subcommand stubs, and shared rendering helpers under `render::{table,json,error}`. Each stub today exits 1 with a "not yet implemented" message (or a `{"error": …}` envelope under `--json`); the eight Wave 2 fan-out PRs replace the stubs with thin presenters over `relayburn-sdk`. Global flags mirror the TS CLI's: `--json`, `--ledger-path `, `--no-color`. Per-command flag wiring is deliberately deferred to the fan-out PRs so they can land in parallel without touching `cli.rs`. Smoke test under `tests/smoke.rs` drives the binary end-to-end via `assert_cmd`: - `burn --help` exits 0 and lists every subcommand - `burn --help` exits 0 with non-empty stdout for every stub - bare `burn ` exits 1 with "not yet implemented" on stderr - `--json burn ` emits a JSON error envelope on stdout - `burn --version` exits 0 - unknown subcommands exit non-zero `cargo build -p relayburn-cli` produces a `burn` binary and `target/release/burn --help` runs in ~10 ms on M-series silicon (no model loads at startup). Unblocks the eight Wave 2 fan-out PRs (`summary`, `hotspots`, `overhead`, `compare`, `run`, `state`, `ingest`, `mcp-server`). Parent issue: #248. Coordination notes (#248-b owns `crates/relayburn-cli/src/harnesses/`; #248-c owns the golden-output snapshots) deliberately untouched.

Package changelogs contain package-le ## [Unreleased] +- `relayburn-cli` (Rust): scaffold the clap v4 derive root with global `--json` / `--ledger-path` / `--no-color` flags, eight stub subcommands (`summary`, `hotspots`, `overhead`, `compare`, `run`, `state`, `ingest`, `mcp-server`), and shared `render::{table,json,error}` helpers. Stubs exit `1` with a `not yet implemented` message (or a `{"error": …}` envelope under `--json`); Wave 2 fan-out PRs replace each stub with a thin presenter over `relayburn-sdk`. (#248 part a) - `relayburn-ingest` (Rust): port the per-process gap-warning state machine (`gap` module — `record_session_gap`, `emit_gap_warning`, `count_tool_call_gaps`, `reset_ingest_gap_warnings`, `set_ingest_gap_writer`) and `reingest_missing_content` (`reingest` module). Suppression mirrors the TS surface: one warning per fresh affected session, silent on steady-state, re-fires after the affected set decays back to empty. `relayburn-ledger` adds `Ledger::list_user_turn_session_ids` to power the `reingest_missing_content` skip filter alongside `list_content_session_ids`. (#278) - `relayburn-analyze` (Rust): port the behavioral-pattern detectors (`patterns` module). `detect_patterns` runs retry-loop, failure-run, cancellation-run, compaction-loss, edit-revert, OpenCode skill-recall-dup, OpenCode skill-pruning-protection, OpenCode system-prompt-tax, and edit-heavy detectors against an ordered turn stream, with optional content-sidecar / tool-result-event / user-turn enrichment. Public surface: `detect_patterns`, `DetectPatternsOptions`; per-pattern result structs are re-exported from `findings` (`RetryLoop`, `FailureRun`, `CancellationRun`, `CompactionLoss`, `EditRevertCycle`, `SkillRecallDup`, `SkillPruningProtection`, `SystemPromptTax`, `EditHeavySession`, `SessionPatternSummary`, `PatternsResult`, `PatternEventSource`). (#275) - `relayburn-analyze` (Rust): port the tool-output-bloat detector — Signal A's `BASH_MAX_OUTPUT_LENGTH` static-config check (with `~/.claude/settings.json` + `/.claude/settings.json` loader) and Signal B's cross-harness observed-bloat aggregation, plus the `WasteFinding` adapter. Public surface mirrors `@relayburn/analyze`: `BASH_MAX_OUTPUT_ENV_KEY`, `DEFAULT_BLOAT_TOKEN_THRESHOLD`, `detect_observed_bloat`, `detect_static_config_bloat`, `detect_tool_output_bloat`, `load_claude_settings`, `project_claude_settings_path`, `user_claude_settings_path`, `tool_output_bloat_to_finding`.

As soon as a Wave 2 command rendered a table with `--no-color`, the output would have been broken. Switch to comfy-table's built-in `Table::force_no_tty()`, which disables cell styling at the source. This kills the bug entirely (option c from the review): there's no post-hoc string surgery to get wrong, and codepoints flow through untouched. Add a regression test that round-trips Japanese text and an emoji through `--no-color` rendering and asserts both the cell content and the box-drawing borders survive intact, plus that no escape bytes leak through.
