comfy knowledge resolve "Qwen 2.1" can now offer canonical model IDs when an incomplete family/version name fails resolution. Suggestions are sorted, distinct and capped at five; the command still returns knowledge_unknown_model with exit 1 and asks the caller to clarify, even for one candidate.

Match the family and ordered numeric components, retaining raw Unicode eligibility before lowercase conversion. Preserve declared alias resolution, normalization and precedence. Add CLI regression coverage and document error.details.candidate_ids. Suggestions do not select, download or execute a model, or change consent.

Final candidate: 128d4c358d8f68724d84bb104e795a769e23d922. Compared with independently reviewed b301653c6bd6133f5e9b48ae365b98e1bbc5769d, the only change removes an internal ticket reference from a test-class docstring to satisfy Public Repo Hygiene. Production bytes are identical; test ASTs are identical after excluding that docstring. Independent review of the exact final revision is complete with no findings. The PR is ready for review; ordinary CI and required GitHub approval remain separate gates.

Validation on the reviewed head and a separate clean integration tree with main 7693c4286d83e0d7b5b84865f453610c761511f7 (integration tree a7223d10de3cfe686f447288a8d5ca1e05e65a64), macOS arm64 / Python 3.12.13. The published branch has not been merged into main:

• ruff check ., ruff format --check ., and git diff --check: pass.
• pytest -q tests/comfy_cli/test_knowledge.py tests/comfy_cli/test_knowledge_attach.py: 333 passed twice, zero skipped, with source import/hash assertions and offline isolation.
• Actual catalog contract checks: 21 passed twice, zero skipped.
• Additional boundary/precedence probes: 36 passed twice; three independently baseline-equivalent uppercase long-s assumptions excluded from this supplementary count.
• The preceding candidate's full-suite fail-fast gate (pytest --cov=comfy_cli -x -q .) exited 1: 1 failed / 67 passed at test_cli_permissions_lists_pending_and_names_approve_first. Untouched main reproduces that assertion and four related failures (5 failed / 104 passed). Assertions were not changed.
• The preceding candidate's unrestricted pytest --cov=comfy_cli --cov-report=xml . collected 10,755 tests, reported failures and timed out after 600 seconds. Full pytest is not green; the docstring-only correction does not establish a passing full run.

Earlier pinned-version checks retained 20 matching baseline/candidate cross-version failures; those runs do not pass. Live Windows, Python 3.12.14 and the original end-to-end incident's latency/cost remain unverified. This is a bounded lookup repair, not evidence that the reported incident is resolved.

Initial final-head CI snapshot: Public Repo Hygiene, Ruff, AGENTS integrity, CLA and both Socket checks pass; nine checks remain in progress. No reviews yet. Ordinary automatic CI only; no manual workflow dispatch or rerun.

📝 Walkthrough

Unmatched model queries can return up to five canonical candidate IDs when they meet ASCII family and version matching rules. The CLI includes available candidates and an exact-ID retry hint. Tests and documentation cover candidate filtering and response behavior.

Changes: Model Candidate Suggestions

Layer / File(s)	Summary
Index aliases and match candidates comfy_cli/knowledge.py, tests/comfy_cli/test_knowledge.py	The bundle indexes eligible aliases for candidate matching. Matching accepts queries with an exact family token and numeric components, and returns up to five sorted canonical IDs. Tests cover filtering, alias precedence, and candidate limits.
Report candidates for unresolved queries comfy_cli/command/knowledge.py, tests/comfy_cli/test_knowledge.py, docs/json-output.md	Unknown-model errors include candidate IDs when available and recommend retrying with an exact ID. Tests and documentation cover this response and distinguish suggestions from exact resolution.

- Around line 1693-1707: Update
test_candidates_are_general_sorted_bounded_and_deduplicated so the fixture gives
each model a distinct additional alias, such as a spaced “turbo” alias, to make
deduplication observable. Use whitespace padding in the overlong queries while
retaining valid matching tokens, so the assertions specifically exercise the
MAX_QUERY_CHARS length gate and still expect no candidates.
