fix(server): reject incomplete GLiNER2 extraction items

[xujiantop-crypto]

GLiNER2 entity, relation, and structured extraction can report success after reading only the first word/subword window. Facts beyond that window never reach the processor, and callers receive no item error warning that the result is partial.

Return INPUT_TOO_LONG when an item's actual bounded window leaves user content unread, infer only complete items, and restore their original batch positions. Rejected items have empty extraction output. The queue publishes zero input-token units for every INPUT_TOO_LONG result, including when an adapter reports a positive count; other error codes retain their reported counts. Request/schema validation still runs first. The completeness check accounts for Unicode lowercase offsets, long-word pieces, the subword budget, trailing whitespace, and GLiNER2's internally added sentence end.

This implements the per-item failure option described in #450.

Validation on Linux with the locked workspace and pinned gliner2==1.3.2 processor:

• With the new synthetic regression and only queue_executor.py restored from 18a33c365741a5fe768382578d58d46e3b7df358, mise exec -- uv run --frozen --project . --no-sync pytest -q packages/sie_server/tests/adapters/test_gliner2_complete_text.py -k test_queue_length_error_overrides_reported_positive_billing: 1 failed (INPUT_TOO_LONG kept the reported 7 tokens), 1 passed (the unrelated INFERENCE_ERROR control).

• GLiNER2, shared-window, queue, worker, and HTTP regressions: 657 passed, 12 deselected, using:

  mise exec -- uv run --frozen --project . --no-sync pytest -q \
    packages/sie_server/tests/adapters/test_gliner2*.py \
    packages/sie_server/tests/adapters/test_word_window.py \
    packages/sie_server/tests/test_queue_executor.py \
    packages/sie_server/tests/test_queue_executor_stage1d.py \
    packages/sie_server/tests/api/test_extract.py \
    packages/sie_server/tests/api/test_error_code_hygiene.py \
    packages/sie_server/tests/core/worker

• mise exec -- uv lock --check --project ., mise run lint, and mise run typecheck: passed.

• mise run test: 11,835 passed, 537 skipped, 320 deselected.

Verification run. Processor tests use a stand-in tokenizer and encoder; no model weights or GPU inference were tested. AI assistance was used to prepare the code, tests, and description.

Summary by CodeRabbit

• Bug Fixes
  • Overlong inputs in entity, relation, and structured extraction now receive an INPUT_TOO_LONG error and are excluded from processing.
  • Valid items in mixed requests continue to be processed, with their results and usage counts preserved.
  • Overlong items report zero input tokens, including when metering returns a positive count.

📝 Walkthrough

Walkthrough

GLiNER2 entity, relation, and structured extraction now checks whether each input fits its read window. Incomplete items receive INPUT_TOO_LONG and are excluded from inference. Queue outcomes report zero input tokens for these errors.

Changes

GLiNER2 Extraction Completeness

Layer / File(s)	Summary
Detect incomplete extraction input packages/sie_server/src/sie_server/adapters/gliner2/adapter.py, packages/sie_server/tests/adapters/test_gliner2_complete_text.py	The adapter checks unread non-whitespace content after each item’s read window. Tests cover lowercase handling, punctuation, whitespace, long words, subword limits, and validation order.
Route extraction tasks and preserve item outcomes packages/sie_server/src/sie_server/adapters/gliner2/adapter.py, packages/sie_server/tests/adapters/test_gliner2_complete_text.py, packages/sie_server/tests/adapters/test_gliner2_long_text.py	Entity, relation, and structured extraction use the completeness check. Failed items receive task-specific empty outputs; valid siblings retain their results and positions. Tests verify inference calls and mixed-item behavior.
Set length-error billing and verify responses packages/sie_server/src/sie_server/queue_executor.py, packages/sie_server/tests/adapters/test_gliner2_complete_text.py, packages/sie_server/tests/api/test_extract.py	Queue outcomes set input tokens to zero for INPUT_TOO_LONG while preserving other unit counts. Tests cover missing or positive prior counts, other error codes, and mixed API responses.

Suggested reviewers: svonava

Priority: ⬇️ Low

Merge Risk: ⚪ Minimal · up to b7459

Overlong items return INPUT_TOO_LONG without input-token billing, while valid siblings retain their results. No actionable merge-blocking risk is established; the PR is ready for normal checks.

Security Architecture Review

Security architecture risk: 🔵 Low · up to b7459

The change prevents incomplete extraction from appearing successful and preserves valid items’ positions. No introduced security defect was established. The zero-token billing rule applies beyond GLiNER2, however, and its compatibility with remote usage contracts remains unverified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The effective scope includes every extraction adapter whose formatted queue result carries INPUT_TOO_LONG, not only GLiNER2. The unchanged remote adapter preserves upstream item errors and usage independently, making remote accounting compatibility relevant; production occurrence of positive usage with this particular error remains unestablished.

Trust Boundaries and Controls

• observed — User text reaches the adapter through the existing extraction route and worker pipeline. Task-specific schema, label, and relation checks precede extraction inference. The new completeness gate further restricts which text reaches model calls rather than adding a caller or granting additional authority.

Hardening Proposals

• proposed — Make the shared non-billable INPUT_TOO_LONG contract explicit for all extraction adapters, including remote upstreams, distinguishing measured token consumption from chargeable units. This would resolve the remaining accounting ambiguity without treating it as an established exploit.
