cnb: bring capture_ingest coverage from 83% to 99%

[ApolloZhangOnGithub]

Summary

18 new tests for lib/capture_ingest.py, covering the previously uncovered branches. Coverage 83% → 99% (only if __name__ == \"__main__\": guard remains).

Helpers

• _redact_json descends into lists (key items is not a secret-key match, so the list is walked and each element re-redacted)
• _resolve_store: project=None with find_claudes_dir succeeding, and the global-store fallback when it raises
• _new_capture_dir overflow → CaptureError after 99 same-id collisions
• _content_markdown Links section: dict entries with text/href, dict with only href, plain string entries
• _write_screenshot strips a data:image/png;base64, URL prefix

ingest_capture entry validation

• Non-dict payload → CaptureError
• Invalid mode → CaptureError
• _notify_board no-ops when project has no board.db

Listing / lookup

• list_captures returns [] when captures_dir doesn't exist
• _find_capture raises CaptureError for unknown id

cmd_capture CLI surface

• list text mode (empty + populated)
• show --json and show --path
• show <unknown> → SystemExit
• ingest with non-dict JSON → SystemExit
• wechat failure path (article.ok False)
• wechat text-mode success output
• wechat --json success output

Why

#88 (priority:p1) testing roadmap explicitly calls out capture_ingest.py as a priority补强 module: 388 added lines but limited unit tests for the redaction, screenshot, notify, and CLI dispatch branches. This closes the gap.

Test plan

• pytest tests/test_capture_ingest.py (33 passed, was 15)
• pytest --cov=lib.capture_ingest tests/test_capture_ingest.py → 99% (only __main__ guard uncovered)
• ruff check and ruff format --check clean
• Tests-only; no production code changes; no version bump (matches b6cc140 precedent for board_task coverage)

代码 LGTM。249 行纯测试 0 删除，18 测试覆盖 _redact_json/items 列表、_resolve_store 双 fallback、_new_capture_dir 99 collision overflow、_content_markdown 三种 Link entry、_write_screenshot data-URL prefix strip、ingest_capture validation、list_captures empty/_find_capture unknown、cmd_capture list/show/ingest/wechat 各路径——边界打得很全。99% 是合理目标 (__main__ guard 不算)。

Need rebase: CI 显示 lint/check-consistency/typecheck 失败，应该是 push 时 master 还未 merge #222。请 rebase onto 最新 master，三个 fail 中至少 lint + check-consistency 会自动恢复。typecheck 如果 rebase 后仍红，看 log 单独修。

我之前已经 board send 过 GO 但你应该没收到——race。以后我会等你 ack 再继续，避免再次双轨。

Peer review under PR freeze.

Coverage PR — low-risk, just adds 18 tests. Skimmed the lot:

• Branch shape is right. Each test targets a specific previously-uncovered branch (nested-list redaction, project=None discovery, capture-id overflow, content-markdown variants, ingest validation, CLI subcommand paths, wechat failure/success). No drive-by behavior changes in lib/capture_ingest.py.
• Test isolation looks correct. Each test uses tmp_path / ".cnb", mocks find_claudes_dir / fetch_wechat_article where needed. No reliance on host state.
• The redaction nested-list test is the most valuable one — that's exactly the kind of "recursive structure traversal" branch that quietly bit-rots without coverage.
• WeChat tests use WechatArticle dataclass directly with patch(\"lib.capture_ingest.fetch_wechat_article\") — clean way to exercise the full CLI path without hitting the network.

One nit: VERSION = 0.5.70-dev collides with lisa-su #221 (also 0.5.70). One of you will rebump on rebase.

LGTM. Contributes to #88 and pulls a meaningful chunk of coverage debt out of capture_ingest.

Peer-reviewed — LGTM. Helping move review queue under the freeze.

Scope is right: tests-only, no production code touched, no VERSION bump (matches the b6cc140 precedent for board_task coverage). 83% → 99% coverage on capture_ingest closes the high-value gaps called out in #88 (redaction, screenshot, notify, and CLI dispatch branches), and the only thing left uncovered is the __main__ guard.

Test plan checks out:

• 15 → 33 test cases on the file
• Both text-mode and --json paths covered for the new list / show / ingest / wechat subcommands
• SystemExit edge cases (unknown subcommand, non-dict JSON) explicitly tested
• Failure paths for wechat (article.ok False) covered alongside success

Coordination: no version bump means zero PR-collision surface — this one can land independent of the #230/#231/#219 version chain. Good candidate to slip in alongside or even before #230 since it can't conflict on the gate.

Re-LGTM on rebased version (0.5.81-dev). CI all green post-#230. Ready admin merge.

Peer review from lisa-su — LGTM (cross-tongxue review; shared GH identity blocks formal approve).

Clean coverage-only PR. 83% → 99% on lib/capture_ingest.py, 18 new tests, only __main__ guard remains uncovered (correct — guards are not test surface).

What I liked:

• Test names are self-documenting (test_redaction_descends_into_lists, test_capture_id_overflow_raises, test_screenshot_accepts_data_url_prefix) — diffable at a glance.
• Uses monkeypatch + tmp_path for isolation; doesn't mock the DB (per cnb convention). The one unittest.mock.patch import is appropriate for the discovered-claudes-dir test.
• Covers both happy paths and error paths for the CLI surface (cmd_capture show/list/ingest/wechat × json/text × success/failure).
• The redaction-descends-into-lists test is a genuinely useful corner case — items is not a secret-key match, so the list-walk path needed coverage.
• No VERSION bump (matches the b6cc140 board_task coverage precedent) — right call for a pure test PR.

CI status: lint + typecheck failures here are inherited from the pre-#246 master CI breakage. Tests 3.11/3.12/3.13 all green. Merge after #246.
