-### Capability naming overhaul
-
-Renamed all capabilities to follow a consistent `domain.resource.action` pattern. Key renames include:
-- `pr.comments.list` → `pr.thread.list`, `pr.comment.reply` → `pr.thread.reply`, `pr.comment.resolve` → `pr.thread.resolve`, `pr.comment.unresolve` → `pr.thread.unresolve`
-- `pr.mergeability.view` → `pr.merge.status`, `pr.merge.execute` → `pr.merge`
-- `pr.status.checks` → `pr.checks.list`, `pr.checks.get_failed` → `pr.checks.failed`
-- `pr.reviews.list` → `pr.review.list`, `pr.reviewers.request` → `pr.review.request`
-- `pr.review.submit_approve`/`submit_comment`/`submit_request_changes` → unified `pr.review.submit` with `event` parameter
-- `pr.diff.list_files` → `pr.diff.files`, `pr.ready_for_review.set` → removed (replaced by `pr.update`)
-- `workflow_run.get` → `workflow.run.view`, `workflow_runs.list` → `workflow.runs.list`, `workflow_run.*` → `workflow.run.*`
-- `workflow_job.logs.get` → `workflow.job.logs.raw`, `workflow_job.logs.analyze` → `workflow.job.logs.get`
-- Removed redundant `workflow.run.jobs.list` capability
-
-### New capabilities
-
-- `pr.diff.view` — view PR diff content
-- `issue.labels.add` — add labels to an issue (non-destructive; complements `issue.labels.update`)
-- `pr.create` — create a pull request
-- `pr.update` — update PR title/body/base
-- `workflow.run.view` (renamed from `workflow_run.get`) — now includes GraphQL routing
-
-### GraphQL improvements
-
-- Extracted 3 shared GraphQL fragments (`PageInfoFields`, `IssueCoreFields`, `PrCoreFields`) reducing field duplication across 10 operation files
-- Routed `pr.merge.status` and `repo.view` through GraphQL (preferred) with CLI fallback
-- Added `fetchPrMergeStatus` to the GraphQL client
-
-### Capabilities list enrichment
-
-- `capabilities list` now returns `required_inputs` per capability — agents can skip `explain` calls
-- `--domain` filter for `ghx capabilities list` (e.g., `--domain pr`)
-- Slimmed SKILL.md to reference `required_inputs` in list output
-
-### stdin input support
-
-- `ghx run <task> --input -` reads JSON input from stdin with 10s timeout
-
-### Integration tests
-
-- 58 new integration tests covering all previously untested capabilities

-Refactor CLI capability adapter into domain modules with full unit test coverage.
-
-**Refactoring:**
-
-- Split monolithic `cli-capability-adapter.ts` (2200+ lines) into focused domain modules under `core/execution/adapters/cli/domains/`: `repo.ts`, `issue.ts`, `pr.ts`, `workflow.ts`, `project-v2.ts`, `release.ts`
-- Extracted shared arg-building helpers to `cli/helpers.ts` (`buildRepoArg`, `buildPaginationArgs`, `buildFieldsFlag`, etc.)
-- Added `cli/capability-registry.ts` — auto-discovers all handlers by spreading domain `handlers` maps; `cli-capability-adapter.ts` becomes a thin dispatcher
-
-**Bug fixes:**
-
-- `pr.ts`: Use `rerunAllResult.exitCode` (not `result.exitCode`) in `handlePrChecksRerunFailed` fallback error path
-- `project-v2.ts`: Remove unreachable `SyntaxError` catch branch in `handleProjectV2ItemFieldUpdate` (no JSON parsing on the success path)
-- `release.ts`: Fix misleading error message — `owner`/`name` are already validated by `requireRepo`; only `releaseId` can be invalid at that point
-- `workflow.ts`: Track total error/warning counts independently of the 10-line collection cap in `handleWorkflowJobLogsGet`; type-narrow artifact `id` field consistently with other normalized fields
-
-**Tests:**
-
-- Added comprehensive unit test suites for all six domain modules (`cli-domains-*.test.ts`) and for the shared helpers (`cli-helpers.test.ts`) and capability registry (`cli-capability-registry.test.ts`) — all modified files at ≥90% branch coverage
-- Refactored e2e tests to use proper `afterEach`/`afterAll` lifecycle hooks instead of ESLint rule suppressions
-
-**Docs:**
-
-- Updated `docs/architecture/adapters.md` and `docs/architecture/repository-structure.md` to reflect the new domain module layout

-Fix `ghx chain` / `executeTasks` batch resolution aliasing bug.
-
-`buildBatchQuery` aliases each GraphQL root field (e.g. `repository`) as `step0`, `step1`, etc. GitHub returns the value directly under the alias key with no wrapper. The engine was storing the unwrapped value, causing `applyInject` to fail when traversing inject paths like `repository.issue.id` in subsequent steps.
-
-Fix: `extractRootFieldName()` is added to `batch.ts` and used in the Phase 1 un-alias loop to re-wrap the raw value as `{ [rootFieldName]: rawValue }` before storing it in `lookupResults`. Adds regression test using real batch/resolve implementations.

+  **Breaking input change** for: `issue.close`, `issue.reopen`, `issue.delete`, `issue.update`, `issue.labels.set`, `issue.labels.add`, `issue.labels.remove`, `issue.assignees.set`, `issue.assignees.add`, `issue.assignees.remove`, `issue.milestone.set`, `issue.comments.create`.
+
+  Each capability now resolves the GitHub node ID internally via a Phase 1 lookup before executing the Phase 2 mutation. This matches the input contract of `issue.view` and enables `ResolutionCache` hits when capabilities are chained together in `executeTasks` calls.
+
+- 58cc7fe: Add structured JSONL execution logging. Emits typed log events at key points in the execution pipeline — preflight checks, route selection, adapter dispatch, all attempt failures (with `retryable` field), and results — written to `~/.ghx/logs/ghx-YYYY-MM-DD.jsonl`. Opt-in via `GHX_LOG_LEVEL` env var (debug/info/warn/error; unset = off). Log directory is configurable via `GHX_LOG_DIR`.

+### Patch Changes
+
+- fb05c12: Refactor CLI capability adapter into domain modules with full unit test coverage.
+
+  **Refactoring:**
+
+  - Split monolithic `cli-capability-adapter.ts` (2200+ lines) into focused domain modules under `core/execution/adapters/cli/domains/`: `repo.ts`, `issue.ts`, `pr.ts`, `workflow.ts`, `project-v2.ts`, `release.ts`
+  - Extracted shared arg-building helpers to `cli/helpers.ts` (`buildRepoArg`, `buildPaginationArgs`, `buildFieldsFlag`, etc.)
+  - Added `cli/capability-registry.ts` — auto-discovers all handlers by spreading domain `handlers` maps; `cli-capability-adapter.ts` becomes a thin dispatcher
+
+  **Bug fixes:**
+
+  - `pr.ts`: Use `rerunAllResult.exitCode` (not `result.exitCode`) in `handlePrChecksRerunFailed` fallback error path
+  - `project-v2.ts`: Remove unreachable `SyntaxError` catch branch in `handleProjectV2ItemFieldUpdate` (no JSON parsing on the success path)
+  - `release.ts`: Fix misleading error message — `owner`/`name` are already validated by `requireRepo`; only `releaseId` can be invalid at that point
+  - `workflow.ts`: Track total error/warning counts independently of the 10-line collection cap in `handleWorkflowJobLogsGet`; type-narrow artifact `id` field consistently with other normalized fields
+
+  **Tests:**
+
+  - Added comprehensive unit test suites for all six domain modules (`cli-domains-*.test.ts`) and for the shared helpers (`cli-helpers.test.ts`) and capability registry (`cli-capability-registry.test.ts`) — all modified files at ≥90% branch coverage
+  - Refactored e2e tests to use proper `afterEach`/`afterAll` lifecycle hooks instead of ESLint rule suppressions
+
+  **Docs:**
+
+  - Updated `docs/architecture/adapters.md` and `docs/architecture/repository-structure.md` to reflect the new domain module layout
+
+- bc10ce8: Fix `ghx chain` / `executeTasks` batch resolution aliasing bug.
+
+  `buildBatchQuery` aliases each GraphQL root field (e.g. `repository`) as `step0`, `step1`, etc. GitHub returns the value directly under the alias key with no wrapper. The engine was storing the unwrapped value, causing `applyInject` to fail when traversing inject paths like `repository.issue.id` in subsequent steps.
+
+  Fix: `extractRootFieldName()` is added to `batch.ts` and used in the Phase 1 un-alias loop to re-wrap the raw value as `{ [rootFieldName]: rawValue }` before storing it in `lookupResults`. Adds regression test using real batch/resolve implementations.
+
+- c4fbcaa: Refactor GQL layer: split monolithic client.ts into lazy-loaded domain modules, add capability registry dispatch, and rename common-types.ts to follow .generated convention. Import cost reduced from ~2,284 lines to ~220 lines via dynamic imports.
+- 89344ca: Replace deep relative imports with `@core/*` path aliases for improved readability and maintainability.
+- 7225358: Harden atomic chaining infrastructure based on review feedback:
+
+  - Register `issue.assignees.add`/`remove` GraphQL handlers (types, mutations, client, capability registry) — these capabilities now route via GraphQL instead of falling back to CLI
+  - Fix `GraphqlError.path` type to `ReadonlyArray<string | number>` per GraphQL spec
+  - Normalize `queryRaw` error handling — HTTP errors now settle consistently regardless of transport implementation
+  - Guard resolution cache against storing `undefined` and sweep expired entries before FIFO eviction
+  - Check `response.ok` before `response.json()` and wrap happy-path parse in try/catch for truncated responses
+  - Use strict `!== undefined` check for step errors instead of truthy check
+  - Extract `buildLookupVars` helper to eliminate duplication in engine
+  - Pass strings directly to `mapErrorToCode` instead of wrapping in `Error`
+
+- bc10ce8: Improve `pr.reviews.submit` schema and capabilities list output.
+
+  - Add `startLine` and `startSide` fields to `pr.reviews.submit` for multi-line comment ranges
+  - Document the `side` vs `diffSide` naming asymmetry between submit input and `pr.threads.list` output
+  - Annotate `body` conditionality: required for `COMMENT`/`REQUEST_CHANGES`, optional for `APPROVE`
+  - Clarify `pr.reviews.list` description to note it returns review-level metadata only (not inline thread comments)
+  - Show array item field hints in `capabilities list` text output (e.g. `comments?[path, body, line, side?, startLine?, startSide?]`)
+
