fix-forward #2847 (tsk-xiinm2): add the fenced RED run the card's ACCEPTANCE demands (knowledge_monitor: 60 items polled / text not overwritten / failed fetch keeps baseline) - #2947
Conversation
…itor bugs, no code change Supersedes #2847 (exec/tsk-xiinm2). The merge gate for R2-12 (RED-FIRST) requires a fenced block showing the acceptance tests FAILING before the fix and PASSING after. PR #2847 carried the fix, the fragment and tests (tests/test_knowledge_monitor.py +148) but no fenced red run in the body. BASE: exec/tsk-xiinm2 (commit 40f2a29, fix already applied). Zero source/test-file diff versus BASE; this commit only carries the red-then-green evidence in the body (commit body becomes the PR body). Red run: scratch worktree on origin/dev (knowledge_monitor.py + knowledge_store.py un-fixed), with ONLY tests/test_knowledge_monitor.py checked out from BASE: ``` FAILED tests/test_knowledge_monitor.py::test_monitor_polls_all_ready_items - AssertionError AssertionError: Expected 60 due items, got 50 assert 50 == 60 FAILED tests/test_knowledge_monitor.py::test_monitor_does_not_overwrite_text_with_raw_html - AssertionError AssertionError: Content should not be overwritten with raw HTML, got: <html><body>Raw HTML content</body></html> assert '<html><body>.../body></html>' == 'original content' FAILED tests/test_knowledge_monitor.py::test_monitor_does_not_update_baseline_on_failed_fetch - AssertionError AssertionError: Baseline hash should not change on failure assert 'e3b0c44298fc...5991b7852b855' == 'aaaaaaaaaaaa...aaaaaaaaaaaaa' 3 failed, 12 deselected, 2 warnings in 0.43s ``` Green run (on BASE exec/tsk-xiinm2, fix applied - get_due_items pages through all ready items, poll_item skips content update on raw HTML, baseline hash only updated when new_content is non-empty): ``` 3 passed, 12 deselected, 2 warnings in 0.24s ``` Closes #2847.

📝 WalkthroughWalkthroughThe knowledge monitor now retrieves all ready items through pagination, preserves stored extracted text during polling, and avoids changing the baseline hash after failed fetches. Tests cover each fix. ChangesKnowledge monitor fixes
Estimated code review effort: 3 (Moderate) | ~20 minutes Severity of issue fixed: Medium Merge Risk: 🟠 High · up to Knowledge monitoring can still generate false updates, mishandle failed fetches, and become increasingly expensive for large collections.

WARNING: Removed SQL LIMIT/OFFSET causes full table scans
Removing LIMIT ? OFFSET ? from the SQL and doing Python slicing instead means fetchall() now loads every matching row into memory. Combined with get_due_items pagination, this results in repeated full-table scans on every page.

WARNING: Mock response missing text attribute
Setting response.aiter_bytes to an async function causes stream_text_response to fall back to resp.text, but response.text is never set on the mock. The fallback returns empty bytes, so this test passes only because the broken mock accidentally simulates a failed fetch — not because raw HTML is correctly handled.

Use a synchronous mock for raise_for_status.
_fetch_article() calls resp.raise_for_status() without await. AsyncMock(side_effect=...) returns a coroutine, so this line does not raise the intended error. Use Mock(side_effect=Exception("Network error")).

Compare the same content representation.
_fetch_article() compares raw HTML with the stored extracted text. This branch keeps the extracted text unchanged. An unchanged article can therefore report changed=True on every poll. Each poll then creates a changed snapshot and resets the interval to the base frequency.
Extract text before comparison. If extraction is not available, do not report a raw-HTML difference as a content change.

Track fetch success separately from content emptiness.
("", False) now represents a failed fetch, but an empty successful response has the same value. Also, poll_item() creates a sha256("") snapshot before this guard runs. Failed fetches still add incorrect empty-content snapshots, while valid empty responses never update last_hash.
Return an explicit fetch-success result. Gate snapshot and baseline updates on that result.

Keep pagination in SQLite.
list_items() now converts every matching row before it applies the requested slice. MonitorService.get_due_items() calls this method once per 100 items. A collection of n ready items therefore performs repeated full reads and conversions, with quadratic work per poll cycle.
Return early when limit <= 0. Add LIMIT ? OFFSET ? to the SQL query. Convert only the fetched page.

LEAD REVIEW (09-10 12:2xZ): the fix-forward job itself is done right - I measured the three acceptance tests in a scratch worktree: 3 failed on origin/dev, 15 passed on this head; head is body-only over BASE exec/tsk-xiinm2 and BASE is an ancestor. BOUNCED on the BASE fix it carries (diffed against merge-base b7d20d9), which is not mergeable:

CARD TITLE (intent, not commit subject): fix-forward #2847 (tsk-xiinm2): add the fenced RED run the card's ACCEPTANCE demands (knowledge_monitor: 60 items polled / text not overwritten / failed fetch keeps baseline)
Autonomous build of board card tsk-kl7vty.
REVISION: built on
exec/tsk-xiinm2(cut at40f2a2969a9c1da146f8bb73519d02ff227bbd99), not ondev. That branch'scommits are ancestors of this one. Verified by
git merge-base --is-ancestorbefore the PR was opened.
Supersedes #2847 (exec/tsk-xiinm2). The merge gate for R2-12 (RED-FIRST) requires
a fenced block showing the acceptance tests FAILING before the fix and PASSING
after. PR #2847 carried the fix, the fragment and tests
(tests/test_knowledge_monitor.py +148) but no fenced red run in the body.
BASE: exec/tsk-xiinm2 (commit 40f2a29, fix already applied).
Zero source/test-file diff versus BASE; this commit only carries the
red-then-green evidence in the body (commit body becomes the PR body).
Red run: scratch worktree on origin/dev (knowledge_monitor.py + knowledge_store.py
un-fixed), with ONLY tests/test_knowledge_monitor.py checked out from BASE:
Green run (on BASE exec/tsk-xiinm2, fix applied - get_due_items pages through all
ready items, poll_item skips content update on raw HTML, baseline hash only
updated when new_content is non-empty):
Closes #2847.
