# Changelog All notable changes to this project will be documented in this file. The format is based on [Keep a Changelog](https://keepachangelog.com/), and this project adheres to [Semantic Versioning](https://semver.org/). ## [Unreleased] ## [0.11.1] - 2026-07-05 ### Added - **Release workflow guidance**: contributor guidance now requires operators to inspect the tag-triggered GitHub Actions release workflow, individual job state, job logs, GitHub Release assets, and npm registry state before claiming release or publish success. It also records the release invariant that releases must be cut only from version-tagged commits already on `main`; release branches, pull request heads, local-only commits, and untagged commits are not release authorities. ## [0.11.0] - 2026-07-05 ### Added - **Obstruction receipt projection preservation**: Edict projection bundles now include an explicit `echoReceipt` slot so future Edict projection providers can pass Echo obstruction receipt review payloads through Graft without reclassifying them as hard rejections or scheduler counterfactuals. Graft preserves the outcome kind, Target IR digest, reason kind, reason payload, and opaque receipt review object, while rejecting top-level `receiptDigest` fields until canonical Echo receipt bytes exist. `StructuredBuffer` keeps the default Edict CLI request limited to syntax, diagnostics, Core, and Target IR; this slice does not execute Echo, admit Jim artifacts, canonicalize receipt bytes, or interpret obstruction semantics. - **Profile-aware Wesley SDL provider seam**: projection registries can now register a Wesley provider for `.graphql` and `.graphqls` buffers. When a `projectionProfileResolver` resolves `wesley-sdl` authority context, `createStructuredBuffer(...)` and `createProjectionBundle(...)` pass dirty buffer text, basis, emit set, and the exact `ResolvedAuthorityContext` to the provider, surface Wesley syntax and diagnostics through the common projection slots, expose the Wesley projection sidecar through `StructuredBuffer.wesleyProjection()`, and preserve authority-owned payload lanes without interpreting descriptor semantics. Wrong-profile diagnostics remain provider-owned, mismatched registry provider kinds fail closed, and provider failures surface as `PROJECTION_PROVIDER_UNAVAILABLE`. This slice does not add TOML discovery, Wesley CLI/WASM transport, Echo execution, Jim admission, or settlement authority. - **Projection authority context bundles**: `createStructuredBuffer(...)` and `createProjectionBundle(...)` can now accept a `projectionProfileResolver` plus optional `profile` override, attach the resolved authority context to warm projection bundles, and pass that same context to registry-routed providers. Bundles distinguish `not_configured`, `resolved`, and `failed` authority states so editor hosts can display profile ids, profile digests, routing digests, provider ids, language ids, and semantic extension identities before the profile-aware Wesley provider lands. Resolver failures are surfaced as structured projection results and skip provider invocation; this slice does not parse `graft.projections.toml`, interpret Wesley SDL, run Echo, admit Jim artifacts, or claim settlement authority. - **Projection profile resolver**: editor hosts can now construct an in-memory `ProjectionProfileResolver` with `createProjectionProfileResolver(...)` to resolve dirty-buffer names to projection authority context before the profile-aware Wesley provider lands. The resolver computes deterministic `profileDigest` and `routingDigest` review strings, treats blank profile overrides as absent, returns structured failures for unknown profiles, ambiguous route matches, and no-provider cases, and keeps profile identity separate from routing identity. Resolver config rejects lossy digest preimages, sparse option arrays, fallback/profile language mismatches, negated route globs, and malformed fallback file extensions before resolution. Profile digests preserve JSON option keys named `__proto__` and are independent of semantic extension declaration order using locale-free code-point comparison. The resolver itself does not parse `graft.projections.toml` or interpret Wesley SDL, descriptor, Echo, Edict, or Colorful semantics. - **Projection provider registry**: editor hosts can now create a `ProjectionProviderRegistry`, register an Edict provider by language id and file extension, and pass the registry to `createStructuredBuffer(...)` or `createProjectionBundle(...)`. The registry routes `.edict` buffers through the existing Edict projection provider, supports explicit `language` routing for synthetic dirty buffers, and keeps the direct `edictProjector` option for compatibility. Blank language ids are treated as absent during registry lookup. The registry is a routing shell for current and future provider bindings only; it does not execute Echo, admit bundles, or make Graft own language-specific semantics. - **Edict projection bridge**: buffer-native editor integrations can now opt into an `EdictProjectionProvider` for `.edict` buffers. Graft exports `createEdictCliProjectionProvider(...)` and `EdictProjectionError`, shells out through the existing `ProcessRunner` port, sends dirty source text to Edict over stdin JSONL, maps Edict syntax byte offsets into Graft row/column spans, preserves compiler diagnostics, and exposes Core/Target IR projection slots with explicit `not_requested`, `available`, `blocked`, and `failed` states. Without a projector, `.edict` buffers are recognized and report `PROJECTION_PROVIDER_UNAVAILABLE`; this bridge does not execute Echo or admit bundles. ### Fixed - **XML and SVG projection authority failures**: native XML/SVG syntax, outline, diagnostics, and fold projections now preserve `PROJECTION_AUTHORITY_UNAVAILABLE` instead of emitting fallback projection lanes when explicit profile resolution fails. ## [0.10.1] - 2026-06-25 ### Added - `graft --version` and `graft -V` now print the package version, and grouped help includes the same version identity without requiring repository or daemon initialization. ### Fixed - **Colorful prose IR compatibility**: the prose projector now accepts `OutlineNode.nodeId: Int!` and `childNodeIds: [Int!]!` from the real `colorful.syntax/v1` contract, normalizing those integer IDs to Graft's internal string keys instead of rejecting valid `colorful ir` output. - **Wesley release gate source**: CI and release workflows now install the project-declared `wesley-cli` from crates.io instead of a pinned Git revision, and the structural-history codec artifact has been regenerated with `wesley-cli 0.1.0` plus Graft's deterministic `Hash`/`Json` scalar shims. ## [0.10.0] - 2026-06-24 ### Added - **Colorful prose projection seam**: buffer-native projections can now opt into a `ProseProjectionProvider`, and Graft exports a Colorful CLI adapter for hosts that want `.txt` buffers projected through `colorful ir -` from `colorful >= 0.2.1`. The projector validates `colorful.syntax/v1`, the pinned vocabulary hash, the source content hash, and UTF-8 byte ranges before returning normal Graft syntax spans, paragraph/sentence outlines, and jump tables. MCP `file_outline` and large-file `safe_read` calls now use that adapter when `colorful >= 0.2.1` is available on `PATH`, while unsupported `.txt` behavior remains unchanged when no projector is configured or the CLI is unavailable. - **Structural basis kind for unpinned committed history**: structural-history schema v0.2 adds `UNPINNED_COMMITTED` so committed git-warp readings with no `ref` and no `head` no longer masquerade as `GIT_REF` rows with a null `refName`. Wesley-generated declarations, LE-binary codecs, manifest hashes, the Echo package descriptor, and generated-model parity tests now pin that `GIT_REF` means a named ref basis. - **Generated-model parity for structural readings** (slice 4, last Graft-only pre-Echo slice): `src/echo/structural-reading-generated-model.ts` maps git-warp-backed `StructuralReadingResult` values onto the Wesley-generated `StructuralReading`/`StructuralReadingEvidence`/ `StructuralBasis` triple and back, loss-free. Ids and payload digests are sha256 over canonical JSON (deterministic, no clock, no randomness); the mapping refuses to emit `ECHO_NATIVE` from translated substrates with a typed error naming the `fallback_translated_is_not_native_continuum` invariant, and the reverse path raises typed obstructions for generated-only enum values, digest mismatches, and mismatched pairs. Parity fixtures prove `graft_dead_symbols` and the `graft_review` reference-count path produce deep-equal output through the generated-model round-trip. Public behavior is unchanged. ### Changed - **Release security floor**: release packaging now resolves Vite and Hono to patched versions required by the release security gate. - **Graft-managed workspace registry hardening**: workspace observation now serializes first-time installation ID creation, fails closed when managed storage cannot be made private, rejects symlinked or unsafe registry storage records before reading them, quarantines unsupported registry metadata instead of reusing it, rejects malformed installation IDs, recovers stale first-time installation locks, caps remote collection during daemon authorization, strips userinfo from scp-like and malformed URL-style remote URLs, preserves spaces in daemon-collected remote paths, serializes concurrent first workspace observation, and only lets observations without explicit repository evidence reuse unknown incarnations that have no durable cache or history attachments. Strong same-path replacement evidence now quarantines the prior incarnation directory before advancing the workspace pointer. - **Workspace-store contract taxonomy**: Slice 0 conformance failure codes are now all included in the frozen `errorTaxonomy`, and the contract test rejects covered conformance rows whose failure codes are absent from that taxonomy. ## [0.9.0] - 2026-06-10 ### Added - **Fake Echo-shaped TypeScript witness**: Graft proves its Echo-facing seam before any real Echo runtime exists. The canonical schema gains its first Intent (`recordGitWarpImportBatch`), Wesley 0.0.5 emits LE-binary var codecs (`src/generated/graft-structural-history.codec.generated.ts`), and a new app-safe stack — `EchoKernelTransport` byte seam, EINT v1 + canonical-CBOR envelope codec, typed structural-history client, and an Echo-backed `StructuralReadingPort` adapter mapping Echo's `ContractObstructionKind` taxonomy into Graft freshness/residual posture — is exercised end to end by a deterministic fake transport. The fake mirrors Echo's wire-level authority enforcement (`FORBIDDEN_CONTROL_INTENT` for the reserved control op id), and guard tests keep the Echo adapter out of production contexts. No public surface changes. - **Structural-history Echo package descriptor**: Graft now carries a deterministic descriptor for the structural-history package it expects Echo to host later, with repo-root-relative schema and generated-artifact identities, descriptor-only Echo posture, and a local drift check wired into `pnpm schema:structural-history:check`. - **Structural history schema authority**: Graft now carries a canonical `schemas/graft-structural-history.graphql` schema with Wesley-generated TypeScript contracts and a deterministic artifact drift check, establishing the schema-first Echo migration boundary without changing Echo or Wesley. - **Structural source span invariants**: The canonical structural-history schema now rejects source spans whose end offsets or present end lines precede their starts. - **Opened workspace paths**: MCP sessions can now call `workspace_open` to open another git worktree path, activate it by default, and inspect opened paths through `workspace_list_opened` without adding per-tool `cwd` routing. - **Symbol history locations**: `graft_blame` and `graft symbol history` now carry per-version path and available line-range facts from WARP symbol timelines without adding a second `code_show` history response shape. ### Changed - **Structural history generation gate**: `pnpm schema:structural-history:check` now requires a configured Wesley CLI, verifies the pinned CLI version and L1 registry hash, regenerates the TypeScript artifact from GraphQL, and byte-compares it with the committed generated file. CI and release workflows install Wesley from a pinned release commit before running the check, and `pnpm release:check` includes the same gate. - **Structural reading boundary**: `graft_review` impact counts and `graft_dead_symbols` now read through a Graft-owned `StructuralReadingPort` with explicit `echo-native`, `git-warp-imported`, and `fallback-translated` evidence labels, preserving existing public response shapes while preventing current git-warp readings from masquerading as Echo-native witnesshood. ### Fixed - **Structural reading residual posture**: Reference-count readings now report a partial residual posture when committed import-scan fallback evidence is unavailable after a zero-count WARP graph reading. ### Security - **Dependency audit posture**: Patched audited transitive dependencies through pnpm overrides for `brace-expansion` and `qs`, preserving a clean release security gate. ## [0.8.0] - 2026-05-13 ### Added - **Top-level structural review CLI**: `graft review --base [--head ]` now renders a human-readable structural review summary from the existing `graft_review` model, while `--json` keeps the schema-validated `graft.cli.struct_review` payload for agents. - **Structural test coverage map**: `graft_test_coverage` and `graft struct test-coverage [--src ] [--tests ]` now report exported source symbols with or without bounded test-directory references, explicitly labeled as structural/reference coverage rather than execution coverage. - **Git enhance provenance hints**: `git graft enhance --since ` now adds a bounded provenance-hints section for changed symbols using WARP-backed blame facts when available, including ambiguity, creation/signature-change commits, reference count, and unavailable blame reasons. - **Symbol history timeline**: `graft symbol history [--path ]` now renders a timeline-first human view over the existing provenance-backed `graft_blame` facts while preserving the `graft.cli.symbol_blame` JSON schema. - **Dead symbol detection**: `graft_dead_symbols` and `graft struct dead-symbols [--limit ]` now list symbols removed from indexed WARP history and not subsequently re-added. - **Review cooldown status helper**: `graft review cooldown [--pr ]` now reads PR comments via `gh pr view --json comments`, detects CodeRabbit rate-limit markers, and reports local ready, cooldown, or unknown status; `--comments-file` supports fixture-backed checks. - **Rust structural parsing**: parser-backed outlines, governed reads, structural diffs, and WARP indexing now recognize `.rs` files using the bundled Rust tree-sitter grammar. - **GraphQL structural parsing**: parser-backed outlines, governed reads, structural diffs, and WARP indexing now recognize `.graphql`, `.gql`, and `.graphqls` files using a compatible GraphQL tree-sitter WASM grammar with GraphQL-specific outline kinds for objects, fields, inputs, scalars, unions, directives, operations, fragments, schema declarations, and enum values, with fixture coverage for Continuum/Wesley-style contract schemas. - **Python structural parsing**: parser-backed outlines, governed reads, structural diffs, and WARP indexing now recognize `.py` and `.pyi` files using the bundled Python tree-sitter grammar. Outlines cover functions, async functions, classes, public methods, class fields, and uppercase module constants. - **Go structural parsing**: parser-backed outlines, governed reads, structural diffs, and WARP indexing now recognize `.go` files using the bundled Go tree-sitter grammar. Outlines cover packages, functions, receiver methods, structs, interfaces, constants, and variables. - **JSON structured config projection**: parser-backed outlines, governed reads, structural diffs, and WARP indexing now recognize `.json` files using the bundled JSON tree-sitter grammar. Outlines summarize top-level config keys with bounded nested object children. - **TOML structured config projection**: parser-backed outlines, governed reads, structural diffs, and WARP indexing now recognize `.toml` files using the bundled TOML tree-sitter grammar. Outlines summarize tables, array tables, and bounded package/tool fields. - **YAML structured config projection**: parser-backed outlines, governed reads, structural diffs, and WARP indexing now recognize `.yaml` and `.yml` files using the bundled YAML tree-sitter grammar. Outlines summarize top-level keys and bounded nested mapping anchors. - **Docker auto-start helper**: the isolated test runner now attempts to launch Docker Desktop on macOS before failing the Docker daemon preflight, while keeping the existing explicit fallback guidance for unsupported or failed startup paths. - **Bounded WARP semantic enrichment seam**: `indexHead` accepts an optional semantic enrichment provider for explicit-path indexing, emits same-file `calls` edges and `typeof` symbol properties from accepted provider facts, caps per-file semantic facts, and reports unavailable providers without breaking tree-sitter indexing. - **Git version startup guard**: CLI, stdio MCP, and daemon startup now fail early when the installed Git is below the plumbing baseline needed for flags such as `--path-format`. Hosts can also call `ensureGitVersionSupportsGraft(...)` from the root package export. - **Method glossary**: `docs/method/GLOSSARY.md` defines core project terms including WARP, causal provenance, strand, worldline, checkout epoch, and workspace overlay. ### Changed - **Lazy parser runtime**: Tree-sitter and grammar WASM loading now happens through an explicit `ensureParserReady()` path instead of top-level await, reducing cold-start pressure for runtimes that do not parse immediately. - **MCP orchestration staging**: MCP invocation and server construction are split into named stages and factories, preserving tool behavior while reducing orchestration debt. - **Unified governed read logic**: MCP `safe_read` delegates cache and structural-diff decisions to `RepoWorkspace.safeRead`, keeping the MCP and direct library surfaces aligned. - **WARP symbol identity hardening**: symbol-id encoding and decoding now route through `SymIdCodec`, and `indexHead` uses a lighter patch payload estimator instead of serializing full patch JSON for budget checks. ### Fixed - **Structural test coverage review fix**: `graft struct test-coverage` now skips tracked test files deleted from the working tree before running reference searches, so unstaged or staged test deletions degrade to uncovered symbols instead of failing on missing paths. - **Review truth follow-up**: CodeRabbit cooldown detection now ignores unauthored rate-limit text by default, structural test coverage batches symbol reference searches per run, CLI render schemas use strict object definitions directly, and review-facing model/render tests cover empty history plus provenance-hint output. - **Review truth collision follow-up**: CodeRabbit cooldown detection now returns unknown when any authored rate-limit marker lacks timestamp or duration evidence, and structural test coverage avoids substring matches while attributing duplicate exported symbol names to the referenced source file. - **Structural review PR feedback**: `graft review` and `graft struct review` now require `--base` at parse time, nested object-literal defaults no longer compact into malformed signatures, and Rust impl/trait extraction uses the grammar's `body` field without a dead fallback. - **PR review hardening follow-up**: Docker auto-start polling no longer uses `Atomics.wait` on the main thread, Docker probe subprocesses are bounded, parser warmup fire-and-forget paths consume rejected promises, `SymIdCodec` rejects malformed IDs and escapes delimiter characters, WARP structural path filters are directory-boundary safe, the MCP server passes injected Git clients through `ToolContext`, and playback tests avoid Node 21-only `import.meta.dirname`. - **Release gate stability**: the Docker-isolated test runner now bounds default Vitest worker concurrency unless an explicit `--maxWorkers` argument is supplied, keeping full-suite release validation stable under constrained Docker resources. - **Parser readiness follow-up**: root library hosts can now call `ensureParserReady()` before synchronous structured-buffer use, while pre-warm sync projection bundles return explicit partial parser unavailable results instead of throwing. Outline cache writes are best-effort after successful governed reads, lazy outline snapshots share in-flight work, and WARP indexing reuses the parsed tree for outline extraction. - **Projection bundle README example**: direct `StructuredBuffer` usage now shows explicit disposal, while `createProjectionBundle(...)` is documented as the lifecycle-owning wrapper. ## [0.7.1] - 2026-04-30 ### Fixed - **npm package runtime shape**: The published package now ships built `dist/` output without `src/`, keeps `tsx` as development-only tooling, runs the package bin and generated Claude hook commands from compiled JavaScript, migrates generated v0.7.0 Claude hook commands through `graft init --write-claude-hooks`, declares targeted `sideEffects` metadata for parser initialization, pins the patched `postcss` transitive used by Vite, and guards manual publishes with `prepublishOnly`. ## [0.7.0] - 2026-04-30 ### Added - **Sludge detector**: `doctor` can run an opt-in parser-backed structural smell scan with `sludge: true` or `graft doctor --sludge`. It reports typedef/class imbalance, JSDoc cast density, homeless constructor functions, free functions operating on project types, and high-symbol-count files. - **Refactor difficulty score**: `graft_difficulty` and `graft symbol difficulty` report a scalar per-symbol refactor score from WARP churn curvature and reference-edge friction. - **WARP snapshot indexing**: `indexHead` is now the canonical snapshot-based indexing path and emits commit, file, directory, symbol, and AST facts with tick metadata. - **Cross-file import resolution**: WARP now records import, re-export, and namespace reference edges for graph-native reference queries. - **Outline-diff commit trailer**: `formatStructuralDiffTrailer` + `parseStructuralDiffTrailer` for embedding structural diffs in git commit messages as machine-readable trailers. - **Background indexing with monitor_nudge**: `monitor_nudge` MCP tool triggers immediate re-index for a running monitor. For post-commit hooks to notify graft that HEAD changed. - **Structural drift detection**: `checkNumericClaim` and `checkPatternProhibition` verify doc claims against reality — numeric counts and pattern prohibitions. - **Drift sentinel**: `runDriftSentinel(ctx, options)` scans all tracked markdown files for stale symbol references against the WARP graph. Returns pass/fail verdict for pre-commit hook use. - **WARP-based reference counting for structural-review**: `graft_review` now counts symbol references via WARP graph traversal instead of ripgrep. More precise (actual imports) and faster (no subprocess). - **Stale docs checker**: `checkStaleDocs` cross-references markdown symbol mentions against the WARP graph to detect outdated docs. `checkVersionDrift` compares CHANGELOG vs package.json versions. - **Session knowledge map**: `knowledge_map` MCP tool answers "what do I already know?" — observed files, symbols, staleness flags, and per-directory coverage. - **Symbol history timeline**: `symbolTimeline(ctx, name, filePath?)` returns every version of a symbol across commits — signature, line range, presence, and change kind, ordered by tick. - **Dead symbol detection**: `findDeadSymbols(ctx, options?)` finds symbols removed from the codebase and never re-added. Supports `maxCommits` depth limiting. Uses WARP snapshot diffs, no grep. - **Monitor tick ceiling tracking**: `runMonitorTickJob` skips `openWarp` and `indexHead` when HEAD hasn't changed since the last indexed commit. Idle monitor ticks are now near-zero-cost. - **Daemon-backed stdio MCP runtime**: `graft serve --runtime daemon` exposes the tested daemon bridge as a release-facing MCP runtime, and `graft init --mcp-runtime daemon --write-*-mcp` can generate client config for daemon-backed stdio instead of repo-local stdio. - **Read-only daemon status surface**: `graft daemon status [--socket ]` renders daemon health, session counts, workspace posture, monitor summary, scheduler pressure, and worker pressure without adding daemon mutation actions. - **Git-facing enhance first slice**: `git graft enhance --since ` and `git-graft enhance --since ` compose shipped structural since and export-surface facts into a concise review summary, with schema-validated JSON available through `--json`. - **Governed exact replacement edit**: `graft_edit` is a narrow MCP edit tool for one exact replacement through Graft's path, policy, schema, and filesystem-port boundaries. - **Agent drift advisory**: `graft_edit` responses can include optional advisory `driftWarnings` when a same-session edit removes then later reintroduces the narrow `jsdoc_typedef` structural pattern. ### Changed - **WARP context boundary**: `WarpHandle` was removed in favor of direct git-warp types carried through `WarpContext`, with fail-closed strand routing hooks for future strand isolation. - **Structural query read paths**: structural queries now use `traverse`, `QueryBuilder`, and tick receipts instead of broad `getEdges()` scans. - **WARP-backed structural operations**: `graft_log`, `graft_churn`, `graft_blame`, and `graft_review` now use WARP graph data for their MCP execution paths. - **Aggregate-backed structural churn**: `graft_churn` now computes live-symbol change counts with WARP `QueryBuilder.aggregate()`, while preserving removed-symbol churn from tick receipt evidence. - **`graft_blame` output shape**: WARP-backed blame returns tick-aware symbol timeline data and a simplified `createdInCommit` value. This is a breaking pre-1.0 MCP schema change for consumers scraping the old result shape. - **Daemon runtime selection**: repo-local `graft serve` remains unchanged, while daemon-backed operation is now an explicit `--runtime daemon` choice with clear setup docs. - **Release scope truth**: full LSP semantic enrichment and the remaining medium-risk slice-first read sweep are preserved as post-v0.7.0 follow-up cards instead of active release blockers. ### Removed - **Legacy commit-walking indexer**: removed the old `indexCommits` pipeline and related model/graph helpers. `indexHead` is the active indexing path. ### Fixed - **Agent worktree hygiene**: added `pnpm guard:agent-worktrees`, wired it into release preflight and the repo-local pre-commit hook, and covered forced embedded-repo gitlinks under `.claude/worktrees/`. - **Export surface semver impact**: `exportSurfaceDiff` now treats breaking signature changes conservatively. Required parameter additions, removed parameters, parameter type changes, and return type changes are `major`; additive optional parameters are `minor`. - **Reference edge scan**: `referencesForSymbol` no longer scans all graph edges; it traverses incoming `references` edges from the target symbol/file node. - **Keep a Changelog version drift**: `checkVersionDrift` now accepts bracketed headings such as `## [0.7.0] - YYYY-MM-DD`. - **Dockerized test isolation**: default `pnpm test` now runs in a copy-in Docker container so validation cannot inherit the operator's live checkout Git hooks or Git environment. - **Full-suite timeout nondeterminism**: test MCP servers and daemon integration tests now use explicit temp-only Git/runtime seams to avoid hidden WARP/server work under full-suite load. - **Repo path symlink-parent escape**: repo path resolution validates the nearest existing ancestor so future create/write tools cannot escape through an existing symlinked parent directory. - **Monitor indexing ceiling**: background monitor ticks now batch explicit paths through the existing `indexHead` cap instead of failing every tick for repos with more than 64 parseable files. - **WARP structural log metadata**: `indexHead` now persists commit message, author, email, date, and timestamp on commit nodes so `graft struct log` retains user-visible commit context. - **Cold WARP structural review impact**: `graft_review` now preserves breaking-change impact counts on fresh worktrees by falling back to a bounded import/re-export scan when graph reference edges are not available yet. - **Backlog dependency DAG**: the checked-in DAG now renders `blocked_by`, `blocking`, and `blocked_by_external` relationships from backlog card frontmatter. ## [0.6.1] - 2026-04-19 ### Fixed - **CI test fixes**: release gate test excludes build artifact `dist/` from existence check. Package docs test updated for moved doc paths. ## [0.6.0] - 2026-04-18 ### Added - **Runtime port guards**: `assertFileSystem()`, `assertJsonCodec()`, and `assertToolContext()` validate adapter contracts at construction time. Plumbing conformance test catches drift against `@git-stunts/plumbing`. - **Secret scrubbing**: shared `scrubSecrets()` and `sanitizeArgValues()` redact sensitive keys, truncate oversized values, and scrub secret patterns across both `run_capture` output and observability arg logging. - **Path escape invariants**: dedicated test suite for traversal attacks, symlink escapes, and root-confinement. - **Worktree identity canonicalization**: `fs.realpathSync` resolves path aliases (`/tmp` vs `/private/tmp`) before deriving workspace IDs. - **Tool-call provenance footprints**: `ToolCallFootprint` records paths, symbols, and line regions per tool invocation. Read-family and search tools instrumented. - **Canonical symbol identity projection**: `graft_diff` and `graft_since` enrich diff entries with `identityId` from WARP `sid:*` anchors when indexed. Graceful degradation when unavailable. - **Dynamic project root**: `GRAFT_PROJECT_ROOT` env var overrides the default `process.cwd()` binding. Git root auto-detection fallback. - **Implicit daemon binding**: daemon-mode sessions auto-bind when a repo-scoped tool is called with path evidence, removing the mandatory `workspace_bind` step. - **Attribution fallback hardening**: transport session, environment inference (CI/CD, editor detection), and session continuity strategies reduce `actor:unknown` to the exception path. - **Anti-sludge policy**: semgrep rules and shell checks for boundary discipline, banned patterns, and core-layer hygiene. - **`toJsonObject()` DTO bridge**: universal serialization boundary between typed operation results and `ctx.respond()`. ### Changed - **Explicit execution context**: `ToolHandler` now receives `ctx` as an explicit parameter `(args, ctx)` instead of closing over it via `createHandler(ctx)`. `AsyncLocalStorage` removed from execution context threading. - **Session concept disambiguation**: `SessionTracker` renamed to `GovernorTracker`, `RegisteredSession` to `RegisteredTransport`, `WorkspaceSessionMode` to `WorkspaceMode`. Wire format preserved. - **MCP composition decomposition**: `server.ts` split into barrel + `server-context.ts` + `server-invocation.ts`. `repo-state.ts` into 4 sub-modules. `daemon-control-plane.ts` into `control-plane/`. `daemon-repos.ts` into `repo-overview/`. `daemon-worker-pool.ts` into 3 sub-modules. `persistent-monitor-runtime.ts` into 3 sub-modules. `workspace-router.ts` gains capability and history sub-modules. - **Parser decomposition**: markdown extraction split into `src/parser/markdown.ts`. Parser reclassified as application module (Layer 3) with enforced hex layer guardrails. - **Result type hardening**: `MetricsSnapshot`, `MetricsDelta`, `DecisionEntry`, `StateSaveResult`, `StateLoadResult` promoted to runtime classes. `[key: string]: unknown` index signatures removed from all operation results. Receipt builder uses mutable draft instead of `as` casts. - **`code_find` approximate discovery**: plain-text queries now use case-insensitive exact/prefix/substring matching with deterministic ranking. - **Claude hook governed reads**: `PreToolUse` now redirects large JS/TS native `Read` calls to graft's bounded-read path. - **Codex bootstrap posture**: `graft init --write-codex-mcp` now seeds `AGENTS.md` alongside `.codex/config.toml`. - **MCP runtime observability**: sessions emit metadata-only events to `.graft/logs/mcp-runtime.ndjson`, receipts carry `traceId` and `latencyMs`. - **Map tool collector extraction**: `map.ts` reduced from 328 to 52 lines; collection logic in `map-collector.ts`. - **Typed diagnostic responses**: `DoctorResponse`, `StatsResponse`, `ExplainResponse`, `SetBudgetResponse`, `RunCaptureResponse`. ### Fixed - **Worktree identity drift on macOS**: `/tmp` and `/private/tmp` aliases no longer produce different workspace IDs. - **`GRAFT_PROJECT_ROOT` env var**: MCP servers no longer hardcoded to their own repo path. - **Path resolver security**: absolute paths now confined to project root. Symlink escapes detected via `fs.realpathSync` double-check. - **WARP symbol disambiguation**: `symNodeId` uses qualified names (`Header.render` vs `Footer.render`) — same-named methods across classes no longer collide. - **WARP indexer error propagation**: `IndexResult` is a discriminated union. Git failures propagate instead of producing silently empty graphs. - **Daemon session cleanup**: session directories removed on close instead of leaking forever. - **Rotating log preservation**: oversized entries preserved instead of erasing the entire log during rotation. - **`graft_map` output caps**: `MAX_MAP_FILES=100`, `MAX_MAP_BYTES=50000` with automatic summary-only fallback. Budget-exhausted sessions get compact `BUDGET_EXHAUSTED` response. - **hono vulnerability**: override to >=4.12.14 patches HTML injection in `hono/jsx` SSR (Dependabot alert #10). ## [0.5.0] - 2026-04-11 ### Added - **Between-commit activity view**: new bounded `activity_view` MCP tool and `graft diag activity` CLI peer surface for inspecting recent local `artifact_history` around the active causal workspace. - **Persisted local history substrate**: continuity, attribution, staged-target, transition, and recent read/stage activity now survive across local sessions as bounded artifact history. - **Same-repo concurrency posture**: bounded `repoConcurrency` summaries and lawful same-worktree cross-session handoff semantics. ### Changed - **Reactive workspace footing**: checkout-boundary footing, hook posture, and forked-vs-stable lineage are now explicit product truth instead of implied inference. - **Semantic transitions**: bounded surfaces now summarize `index_update`, `conflict_resolution`, `merge_phase`, `rebase_phase`, `bulk_transition`, and lawful `unknown` with transition-aware guidance. - **Signpost docs**: README, GUIDE, BEARING, VISION, release notes, and the new CLI/MCP/advanced signposts now reflect the 0.5.0 release cut. ## [0.4.0] - 2026-04-05 ### Added - **WARP Level 1 — structural memory substrate**: git-warp-backed graph stores structural facts per commit. Directory tree, file, symbol, and commit nodes with containment edges and provenance links (touches, adds, changes, removes). - **`graft_since`**: structural changes since a git ref — symbols added, removed, and changed per file with summary lines. Instant. - **`graft_map`**: structural map of a directory — all files and their symbols in one call via tree-sitter. - **`graft index` CLI**: manual WARP indexing trigger. - **WARP indexer**: walks git history, parses files with tree-sitter, emits WARP patches. Handles nested symbols, file deletion, signature changes, unsupported language degradation. - **Observer factory**: 8 canonical lens patterns for focused graph projections (file symbols, all symbols, directory files, etc.). - **11 WARP invariants**: observer-only-access, materialization- deterministic, delta-only-storage, address-not-identity, and more. - **`@git-stunts/git-warp` v16** + `@git-stunts/plumbing` deps. ## [0.3.5] - 2026-04-05 ### Fixed - **CI**: use `npx npm@latest` for OIDC trusted publishing — avoids self-upgrade breakage on Node 22's bundled npm. ## [0.3.4] - 2026-04-05 ### Fixed - **CI**: upgrade npm CLI to >=11.5.1 for OIDC trusted publishing. ## [0.3.3] - 2026-04-05 ### Fixed - **CI**: use `npm publish` instead of `pnpm publish` for OIDC provenance. ## [0.3.2] - 2026-04-05 ### Added - **`graft init`**: zero-friction project onboarding. Scaffolds `.graftignore`, adds `.graft/` to `.gitignore`, generates `CLAUDE.md` snippet instructing agents to prefer graft tools, and prints Claude Code hook config. Idempotent. - **CI**: release workflow attaches npm tarball + SHA256SUMS to GitHub releases as downloadable assets. - **CI**: npm publish via OIDC provenance (no secret needed). ### Changed - **CLI bootstrap**: `bin/graft.js` resolves tsx from the package's own `node_modules`, so `graft init` works from any directory. - **Docs**: regenerated README, GUIDE, BEARING, and VISION signposts. - **package.json**: added `publishConfig`, `homepage`, `bugs`, `packageManager`, upgraded keywords for MCP/agent discovery. ### Fixed - **CI**: removed pnpm version override that conflicted with `packageManager` field. ## [0.3.1] - 2026-04-05 ### Changed - **CI**: release workflow now publishes to npm via OIDC provenance. - **Docs**: regenerated README, GUIDE, BEARING, and VISION signposts to reflect v0.3.0 features (12 tools, budget governor, reason codes). ## [0.3.0] - 2026-04-05 ### Added - **Budget-aware governor**: `set_budget(bytes)` declares a session byte budget. Thresholds tighten as budget drains — no single read may consume more than 5% of remaining budget. New `BUDGET_CAP` reason code. Budget info in receipts. - **Explain tool**: `explain(code)` returns human-readable meaning and recommended action for any reason code. - **Policy check middleware**: tools with `policyCheck: true` get automatic `evaluatePolicy` before the handler runs. Applied to `read_range`. - **CachedFile value object**: immutable file snapshot bundles content, hash, outline, jump table, and actual metrics from a single read. Eliminates TOCTOU snapshot races by construction. - **guardedPort() factory**: Proxy-based stream boundary guard wraps all methods on a port interface. One line to guard a whole port. - **Receipt compression ratio**: `compressionRatio` field in receipts (returnedBytes / fileBytes). Instant context efficiency signal. - **Diff summary lines**: each file in `graft_diff` output includes a one-line structural stat for quick triage. ### Fixed - **Strict MCP argument validation**: Zod schemas now reject unknown keys at the MCP edge instead of silently stripping them. - **run_capture log-write isolation**: filesystem failures when persisting capture logs no longer mask successful command output. - **Cache-hit policy re-check**: `safe_read` now re-evaluates policy on cache hits, preventing stale cached data from bypassing refusals. ## [0.2.2] - 2026-04-04 ### Added - **Docker support**: run graft as an MCP server without installing Node. `docker run -i --rm -v "$PWD:/workspace" flyingrobots/graft`. Node 22 Alpine, non-root user. - **Canonical JSON codec**: all JSON serialization uses deterministic sorted keys and compact output via `CanonicalJsonCodec`. Enables stable hashes and diffable logs. `JsonCodec` port for hexagonal compliance. ### Fixed - **JSON serialization safety**: codec preserves `Date` and custom `toJSON` semantics, detects circular references, handles shared object references without false cycle detection. ## [0.2.1] - 2026-04-04 ### Added - **Value objects** (cycle 0016): OutlineEntry, JumpEntry, DiffEntry, OutlineDiff, and Tripwire converted from plain interfaces to frozen SSJS classes with constructor validation and private `_brand` fields. Completes SSJS P1 migration for all domain types. - **PostToolUse hook for Read**: educates agents on context cost after large file reads, showing what safe_read would have returned and the savings in KB. - **Shared hook utilities** (`src/hooks/shared.ts`): validated input parsing, stdin reader with 1 MB size guard, safe relative path resolution, and `runHook` harness with full stack trace logging. - **18 project invariants** documented in `docs/invariants/`. ### Fixed - **Trim-and-validate**: value object constructors trim names before validation, preventing whitespace-only strings from passing as valid. - **Input validation**: hooks now validate JSON structure at runtime instead of using unsafe `as` type assertions. - **Path traversal guard**: hooks reject file paths outside the project `cwd` (passes through to native Read instead of evaluating policy on arbitrary paths). - **UTF-8 safety**: stdin reader accumulates raw buffers before decoding to prevent multi-byte character corruption at chunk boundaries. - **Stack traces**: hook error handler logs `err.stack` instead of `err.message` for debuggability. - **Node engine**: bump minimum to `>=20.11.0` for `import.meta.dirname` support (used across test suite and eslint config). ## [0.2.0] - 2026-04-03 ### Changed - **Server decomposition** (cycle 0010): split 541-line MCP server god file into focused modules. `server.ts` is now 110 lines of pure registration and plumbing. New modules: - `metrics.ts` — `Metrics` class replaces 6 loose counters - `cache.ts` — `Observation` class + `ObservationCache` with `isStale()`, `touch()`, `record()`, `check()`, `get()` - `receipt.ts` — `buildReceiptResult()` with stabilization loop - `context.ts` — `ToolContext` interface + `ToolHandler` type - `tools/*.ts` — 9 files, one per tool handler (state.ts has both save + load) - **FileSystem port** (cycle 0011): hexagonal compliance — core logic no longer imports `node:fs` directly. New `FileSystem` interface in `src/ports/filesystem.ts` with Node adapter in `src/adapters/node-fs.ts`. All operations and metrics use the port; testable with mock filesystems. - **Outline quality audit** (cycle 0012): 7 real-world fixture files, 40 test assertions proving outline extraction works on React components, Express routers, barrel files, god classes, dense generics, and decorated classes. ### Added - **Arrow function export extraction**: `export const fn = () => {}` now gets `kind: "function"` with parameter/return type signature instead of generic `kind: "export"`. - **Enum extraction**: `enum` declarations appear in outlines with `kind: "enum"`. - **Re-export extraction**: named, type, and wildcard re-exports now appear in outlines. Barrel files are no longer invisible. - **Claude Code hooks** (cycle 0015): PreToolUse hook blocks banned files (secrets, binaries, lockfiles, `.graftignore` matches). PostToolUse hook educates agents on context cost after large file reads, suggesting `safe_read` as an alternative. ### Fixed - **Byte metrics**: receipt builder now uses `Buffer.byteLength()` instead of `text.length` for returnedBytes and cumulative byte accounting. Was counting UTF-16 code units as bytes. - **Path traversal guard**: all path-accepting tools now use `ctx.resolvePath()` which rejects relative paths that escape the project root via `..` segments. - **Doctor thresholds drift**: doctor tool now imports `STATIC_THRESHOLDS` from policy instead of hardcoding values. - **run_capture tail validation**: clamp tail to minimum 1 to prevent zero/negative values from producing undefined behavior. - **safe_read result.actual guard**: check `result.actual !== undefined` before using it for cache recording (actual is optional on error projections). ## [0.1.0] - 2026-04-03 ### Added - **Policy engine**: dual thresholds (150 lines + 12 KB), 5 ban categories (binary, lockfile, minified, build output, secret), `.graftignore` support, session-depth dynamic caps (20/10/4 KB). - **Parser**: tree-sitter WASM outline extraction for JS/TS with jump tables, signature bounding, and broken-file recovery. - **Session tracker**: 4 tripwires (SESSION_LONG, EDIT_BASH_LOOP, RUNAWAY_TOOLS, LATE_LARGE_READ) with session depth reporting. - **Metrics logger**: NDJSON decision logging with retention/rotation. - **Operations**: safe_read, file_outline, read_range, state_save/load. - **MCP server**: all 8 Phase 1 commands as MCP tools over stdio, session tracking (tripwires + dynamic caps automatic), doctor and stats tools. Entry point at `src/mcp/stdio.ts`. - **Re-read suppression**: session-level observation cache — second read of an unchanged file returns cached outline instead of re-reading. Tracks readCount, estimatedBytesAvoided, lastReadAt. Works for both safe_read and file_outline. Stats includes totalCacheHits and totalBytesAvoidedByCache. - **Receipt mode**: every MCP response includes a `_receipt` block with sessionId, monotonic seq, projection, reason, fileBytes, returnedBytes, and cumulative counters (reads, outlines, refusals, cacheHits, bytesReturned, bytesAvoided). Blacklight can grep API transcripts to prove graft works. - **Changed-since-last-read**: when a file changes between reads, graft returns a structural diff (added/removed/changed symbols) alongside the new outline. New `changed_since` MCP tool for explicit delta queries without triggering a full safe_read. - Now 16 machine-stable reason codes — added `REREAD_UNCHANGED` (cycle 0003) and `CHANGED_SINCE_LAST_READ` (cycle 0005). - **Structural git diff** (`graft_diff`): symbol-level diff between any two git refs. Uses `git rev-parse --verify` + `git cat-file -e` for stable ref/object detection. - **run_capture implemented**: tee shell output to log file, return last N lines. Full output at `.graft/logs/capture.log`. - **MCP tool descriptions**: all 10 tools have agent-facing descriptions in their schema for discovery via `listTools`. - **bin/graft.js**: CLI entry point for `npx @flyingrobots/graft`. - 16 machine-stable reason codes. - 227 tests across 20 test files. - 7 cycles completed, 3 legends (CORE, WARP, CLEAN_CODE). ### Fixed - **Diff path policy check**: both `safe_read` and `changed_since` now run `evaluatePolicy` before returning structural data, preventing leaks if policy rules change after initial observation. Note: `safe_read` always evaluates policy; `changed_since` was added in this release and now also evaluates policy. - **Nested symbol diff**: classes/interfaces now recursively diff children. A method added inside a class shows as a changed class with a childDiff detailing the nested change. - **Snapshot race**: diff and changed_since paths now use extractOutline with the already-read content instead of re-reading the file via fileOutline. - **Pre-push hook**: parses stdin for the remote ref being pushed to instead of checking the local branch name. - **oldSignature consistency**: DiffEntry.oldSignature now uses the same entrySignature fallback (name when no signature) as the comparison logic. - **Stale lastReadAt**: diff responses now return the updated timestamp from the observation cache instead of the old one. - **Dead DiffEntry fields**: removed unused start/end from DiffEntry. - Add `@types/node` and `@types/picomatch` (required by TypeScript 6). - Fix session-depth table in design doc ("Messages Remaining" → "Messages Elapsed").
