fix(cli): correct ast command import path after src/ reorganization

[carlos-alm]

Summary

The codegraph ast command crashed with a missing module error because it imported from ../../ast.js (resolving to dist/ast.js), but the module lives at dist/features/ast.js after the src/ reorganization in v3.1.5.

Fixed by updating the dynamic import path to ../../features/ast.js.

Found during

Dogfooding v3.3.0 — see #529

Test plan

• npx codegraph ast call returns results instead of crashing
• npx vitest run tests/integration/ast.test.js — 19 tests pass
• npm run lint — clean (1 unrelated warning)

Reviewing PR: fix(cli): correct ast command import path

Todo List:

• Read and analyze the changed file
• Verify the codebase structure and import path
• Check for similar issues in other files
• Perform root cause analysis
• Assess backlog compliance
• Provide final review rating and recommendation

Root Cause Analysis

Problem Being Solved: The codegraph ast command was importing from ../../ast.js which resolved to the non-existent dist/ast.js after the src/ reorganization in v3.1.5. The AST module was moved to src/features/ast.js during the restructure.

Why This Approach: Direct import path fix is the correct approach. This follows the same pattern as PR #521 which fixed similar import path issues in benchmark scripts after the same reorganization.

Risk Assessment: Minimal risk. Single line change to correct a broken import path. The target file exists and exports the required symbols (AST_NODE_KINDS, astQuery).

Backlog Compliance

• Zero-dep: ✓ — No new dependencies added
• Foundation-aligned: ✓ — Simple bug fix maintaining existing functionality
• Problem-fit: 2 — Bug fix that prevents crashes but doesn't directly address core AI navigation problems
• Breaking: No — Pure bug fix, no API changes
• Tier: 1

Critical Concerns

None. This is a straightforward import path correction.

Code Quality Assessment

• Correctness: ✅ Import path now correctly resolves to existing src/features/ast.js
• Completeness: ✅ No other files have the same broken import pattern
• Consistency: ✅ Follows the pattern established in PR fix: update benchmark script import paths after src/ restructure #521 for similar fixes
• Testing: ✅ Author claims integration tests pass (tests/integration/ast.test.js - 19 tests)

Final Recommendation

• Rating: ⭐⭐⭐⭐☆ (4/5)
• Action: APPROVE
• Reasoning: Clean fix for a real crash bug with proper testing verification. Well-contained change with zero risk of introducing new issues.

Minor deduction: While technically correct, this suggests incomplete validation during the original reorganization that allowed this import to break. Future reorganizations should include automated import validation.

Greptile Summary

This PR fixes a runtime crash in the codegraph ast command caused by a stale import path left behind after the src/ reorganization in v3.1.5. The single-line change updates the dynamic import from ../../ast.js to ../../features/ast.js, which correctly points to src/features/ast.js where the AST_NODE_KINDS constant and astQuery function now live.

The fix is minimal, targeted, and correct — the resolved file exists and exports exactly the named bindings the command requires.

Potential related issue worth investigating (out of scope for this PR):

• src/cli/commands/info.js line 39 has a similar stale import: import('../../db.js'), but src/db.js does not exist after the reorganization (the correct path is ../../db/index.js or ../../db). Because this import is inside a try/catch block that silently swallows errors (/* diagnostics must never crash */), this bug does not crash the info command — instead it silently suppresses all build metadata output. This is worth fixing in a follow-up PR.

Confidence Score: 5/5

• Safe to merge — single-line import path fix that has been verified against the actual file structure.
• The change is a one-line targeted bugfix. The destination module src/features/ast.js exists and exports the exact bindings (AST_NODE_KINDS, astQuery) consumed on the very next lines. The relative path ../../features/ast.js from src/cli/commands/ast.js resolves correctly to src/features/ast.js. No logic changes, no new dependencies, and the PR description confirms integration tests pass.
• No files in this PR require special attention, though src/cli/commands/info.js (outside the diff) may have a similar stale ../../db.js import worth investigating.

Important Files Changed

Filename	Overview
src/cli/commands/ast.js	One-line fix updating the dynamic import path from ../../ast.js to ../../features/ast.js. The target file exists at src/features/ast.js and exports both AST_NODE_KINDS and astQuery as expected.
