Beyond the 5 named presets above, `--preset`/`config.json`'s `preset` field also accept a **composable toolset spec**: a comma-separated list of toolset (module-domain) names — `trace`, `locate`, `orient`, `memory`, `guardrails`, `recover`, `scip`, `lsp`, `security`, `testgap`, `inspect`, `edit`, `patterndebt` — optionally prefixed with `-` to subtract that toolset instead of adding it. E.g. `--preset "trace,security"` unions two toolsets; `--preset "full,-edit"` is every tool except the edit toolset's (`edit_symbol`/`edit_lines`/`format_files`). This is a different, finer-grained axis than the 5 named presets (which are hand-curated cross-cutting workflow bundles, not toolset unions) — an unrecognized token in either syntax is a hard startup error, never a silent full-access fallback. diff --git a/CHANGELOG.md b/CHANGELOG.md index 8710f94b..7542a9fc 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -9,6 +9,20 @@ git tags in [Releases](https://github.com/Eilodon/CALM/releases). ### Added - Opt-in WS-6 first-slice verification (`docs/plans/2026-08-03-ws6-verification-pipeline-execution-plan.md`): `[verification] rust_check_on_write` (default off) routes a `.rs` write through the durable transaction's `VERIFY_PENDING` state instead of straight to `Done`; new `verify_change(tx_id)` tool runs `cargo check` scoped to the nearest Cargo package and advances the transaction to `Done`/`Failed` -- a failed check does not revert the file already written to disk - `plugins/calm/.claude-plugin/plugin.json`'s `version` is now checked against `Cargo.toml`'s (`scripts/check-doc-truth.sh`) so the Claude Code plugin manifest can't silently drift from the release it bundles again +- `verify_change` now binds to the transaction's `proposed_digest`, checked both immediately before and immediately after `cargo check` runs -- a concurrent write can no longer get bound to someone else's verification receipt (`VERIFICATION_SNAPSHOT_CHANGED`) +- `[verification] timeout_secs` (default 120s): `cargo check` is killed if it hangs (a stuck `build.rs`/proc-macro/registry fetch) instead of blocking the tool call indefinitely +- `calm init` now creates `.calm/` atomically at `0700` (matching the daemon's own posture) instead of a plain `create_dir_all` at the umask default; `calm doctor --fix` additionally retightens an already-loose `.calm/` and its sensitive files (`index.db`, `memory.key`, `daemon.log`, `audit.log`, `daemon.sock`) +- Non-loopback `calm serve --http` now forces a capability-derived `remote-safe` preset (every tool declaring `read_only_hint = true`, computed live off the tool router) instead of the old `full,-edit` toolset exclusion, which only ever disabled `edit_lines`/`edit_symbol`/`format_files` -- `remember`, `verify_change`, `retry_maintenance`, `scip_refresh`, `lsp_refresh`, `set_toolset`, and `pattern_debt_register` are now also excluded by default over an unauthenticated-by-default remote transport +- The audit ledger (`audit_ledger`) is now HMAC-SHA256-signed (keyed by a new 0600 `.calm/audit.key`, separate from `memory.key`) instead of a plain unkeyed SHA-256 chain -- an actor with only SQLite file write access can no longer forge a chain that still passes `verify_chain` +- `calm setup --npx` now pins the written entry to `@eilodon/calm-mcp@` by default instead of an unpinned `npx -y @eilodon/calm-mcp`, so a cold `npx` invocation always resolves to the same release; `--track latest` opts back into the old unpinned behavior +- `.calm/config.json` `risk_rules` (default empty): a path-glob-to-minimum-risk floor (e.g. `{glob: "**/auth/**", minimum: "high"}`) that the write gate can never classify below, closing the gap where a low-fan-in but security-sensitive file read as low risk regardless of caller count +- `remember` now quarantines a note whose content trips the prompt-injection heuristic (still saved, same detection-only philosophy) and `recall` excludes quarantined notes from its ambient/broad paths (FTS `query`, no-args list-all) by default -- an exact `topic` lookup still always returns it, mirroring `edit_context`'s existing `related_notes` ambient-surfacing gate +- `KNOWN_LIMITATIONS.md`: an honest catalog of what CALM doesn't do yet and why each gap is deliberately deferred rather than half-built +- Indexing now skips any file over 8 MiB (`read_source_capped`, checked via a cheap `metadata()` stat before ever reading the file) and bounds a single tree-sitter parse to 5s (`Parser::set_timeout_micros`) -- a pathologically huge or deeply-nested file can no longer hang or balloon the indexer's memory +- `compute_touch_risk` now escalates risk to `"high"` when an edit's own proposed content actually changes a touched function/method's signature TEXT (not just overlaps its line range -- a whole-body replace that leaves the signature byte-for-byte identical does not escalate), reusing `diff_impact`'s own `is_signature_semantically_changed`/`escalate_risk_if_signature_changed` +- `calm serve --http` now caps request body size (16 MiB, `axum::extract::DefaultBodyLimit`) and concurrent in-flight requests (64, `tower::limit::ConcurrencyLimitLayer`) as defense-in-depth against the unbounded-resource gap a bare `axum::Router` had; still not a substitute for a reverse proxy's real rate limiting +- New `reference_impact` tool: merges call edges, import edges naming a symbol, and a repo-wide textual grep into one classified reference list (`must_change`/`likely_change`/`review`/`textual_only`) for rename/removal planning -- closes the exact gap behind two real `benchmarks/b7_task_correctness` misses (a bare re-export statement invisible to the call graph alone) +- `edit_lines`/`edit_symbol` gained an optional `cites` param: the EXACT `qualified_name` of a caller `edit_context` returned this session, checked by equality rather than the existing `reason` field's word-boundary substring search -- closes the "paste a real caller name into an unrelated sentence" gaming path for callers that opt in;

VS Code/GitHub Copilot uses the *same* `PreToolUse` / `permissionDecision: deny` shape, so that port should be close to a direct translation. Cursor (`beforeMCPExecution`) and Windsurf (Cascade Hooks) use different shapes and need their own adapters. 2. **Resolver accuracy.** False positives/negatives in `coreness`/`is_hub` classification, edge cases in the SCIP-overlay caching key. Also useful: getting more of the optional SCIP cross-reference providers (Go, Java, C#, PHP, C, Ruby — see `install_hint` in `repo_overview`'s `health_summary`) easier to install, since call-graph precision for those languages is capped without one installed. 3. **New Tier-0.5 → Tier-0 promotions.** SQL and Dart both already ship (SQL has its own standalone `sqlparser`-based indexer — real grammar, not regex — but deliberately stops short of a call graph, since "calls" isn't a coherent concept across SQL dialects; Dart is Tier-0.5 with the known zero-call-edge grammar limit noted above) — the next candidates are whichever Tier-0.5 language your own report from the "try CALM on a Tier-0.5 language" bullet above turns up as highest-friction. +4. **A sandboxed, multi-language execution broker for verification.** `verify_change` runs one check (`cargo check`, unsandboxed beyond a wall-clock timeout and digest binding) — see `KNOWN_LIMITATIONS.md`'s "Verification is single-language..." entry. Extending to `go test`/`tsc --noEmit`/`pytest` needs a shared network/filesystem/env execution-policy abstraction built first, not each language bolted directly onto a bare subprocess call. +5. **`reference_impact(symbol, operation="rename")`.** `benchmarks/b7_task_correctness` has two real failing rename cases today from composing `callers`/`edit_context` by hand instead of having a tool that merges call edges + SCIP references + imports/re-exports + textual matches into one classified list. See `KNOWN_LIMITATIONS.md`'s "No unified reference-impact tool" entry. +6. **Change-kind-aware risk classification.** `compute_touch_risk` sees caller-count/hub-status and (as of this pass) a path-based `risk_rules` floor, but not whether an edit is a comment tweak vs. a signature break vs. an auth-check removal. Needs the diff content turned into a classified axis and folded into the risk model. See `KNOWN_LIMITATIONS.md`. +7. **`calm guard --staged` / a publishable GitHub Action.** The only integration point today is an MCP client calling CALM's tools directly — a native editor edit or a teammate's local commit is invisible to CALM. See `KNOWN_LIMITATIONS.md`'s "No Git/CI-native integration path" entry. +8. **Multi-file change-set / transaction.** Today every `edit_lines`/`edit_symbol`/`format_files` call is its own independent, file-scoped `EditTransaction` — a multi-file refactor has no aggregate success/failure view.

Still genuinely missing: an AST-node budget +for a file that's under the size cap but pathologically nested, and a +`.calm/` disk quota.
