MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implemented the `/fix` follow-up without committing. Key changes: - Snapshot collection now verifies stable head SHAs, detects API caps/incomplete diffs, paginates commit files, uses bounded concurrency, and gathers complete file/config context. - Candidate safety now rejects overlapping “atomic” commits, incomplete analysis, unsafe renames/deletions, missing reverse dependencies, and split manifest/lockfiles. - Expanded dependency analysis across supported languages, path aliases, generated companions, and module-aware tests. - Workflow shell text is display-only; executable validation hints require trusted, repository-aware commands with working directories. - Bounded candidates/prompts and hardened the optional judge with immutable inputs, post-judgement safety checks, and normalized output. - Added comprehensive regression coverage in [analysisPlanning.test.ts](/tmp/git-processor/worktrees/integry/propr/pr-1745-followup-2026-08-04T11-35-11/test/prSplit/analysisPlanning.test.ts).

Implemented the PR #1745 follow-up changes and left them uncommitted. Key updates: - Hardened snapshot consistency, merge-base representation, fork reads, retries, GitHub error handling, and aggregate request/byte/time budgets in [prSnapshot.ts](/tmp/git-processor/worktrees/integry/propr/pr-1745-followup-2026-08-04T12-12-14/packages/core/src/services/prSplit/prSnapshot.ts). - Added ecosystem-specific import resolution, including NodeNext, Python relative imports, aliases, and workspace exports in [dependencyResolvers.ts](/tmp/git-processor/worktrees/integry/propr/pr-1745-followup-2026-08-04T12-12-14/packages/core/src/services/prSplit/dependencyResolvers.ts). - Fixed manifest/config dependencies, candidate IDs, sampling bias, atomic-commit expansion, test-only scopes, and special-dependency matching. - Made validation commands structured, working-directory-aware, candidate-effective, and explicitly sandbox-required. - Bounded prompts/instructions and added judgement deadlines with cancellation signals. - Expanded regression coverage to 32 focused PR-split tests. Verification passed: - Full `test:unit` suite - Root TypeScript typecheck - `@propr/core` lint with no warnings - `git diff --check` No commit or PR was created.

Implemented the PR #1745 follow-up fixes without committing. Highlights: - Fail-closed mixed-hunk, incomplete-content, generated-only, and dependency analysis. - JSONC aliases plus C#, Java, Ruby, and Node imports support. - Directed dependency closures and broader candidate construction. - Immutable merge-base/head diff provenance. - Valid bounded prompts with richer evidence and untrusted-data isolation. - Real agent/process cancellation on planner timeout. - Workspace validation fallback and all allowlisted scripts. - Snapshot retry, request-budget, cancellation, and retained-memory improvements. - Expanded adversarial regressions in [analysisPlanning.test.ts](/tmp/git-processor/worktrees/integry/propr/pr-1745-followup-2026-08-04T12-56-37/test/prSplit/analysisPlanning.test.ts).

Implemented the follow-up without committing. - PR split scope is now authored directly by the LLM from full PR evidence. - Removed deterministic candidate generation, ranking, and dependency-closure modules. - No-LLM execution fails closed. - Deterministic logic is limited to validating the LLM response and safety guardrails. - Updated planner types, exports, and tests.
