Module scraper Future

Scraper Module - Future Enhancements

Scope

• hardening and refinement of scraper ingestion runtime behavior
• deterministic reliability improvements for fetch/extract/evaluate/write paths
• stronger benchmark-backed guardrails for extraction-oriented hot paths

Design Constraints

• scraper contracts remain backward compatible within major release line.
• fetch/extraction/evaluation outcomes remain explicit and deterministic.
• degraded/fallback paths remain observable and non-silent.
• provenance construction remains mandatory for all write paths.

Required Interfaces

Interface	Requirement
fetch interfaces	bounded static/JS/API fetch semantics
extraction interfaces	deterministic form/result extraction behavior
evaluation interfaces	explicit quality/relevance and fallback outcomes
writer interfaces	provenance-safe metadata construction and write signaling

Implementation Notes

• tighten parity between fetch policy decisions and extraction readiness — evidence: include/scraper/scraper_render_contract.h, include/scraper/scraper_burst_controller.h
• standardize diagnostics for crawler/evaluator/writer incident classes — evidence: include/scraper/scraper_diagnostics.h
• [~] expand resilience tests for prolonged multi-source ingest traffic — evidence: tests/scraper/test_scraper_burst_hardening_focused.cpp (SCR-17..20)
• [~] broaden benchmark depth for dedicated scraper pipeline paths — evidence: benchmarks/scraper/bench_scraper_pipeline_depth.cpp (pending)

Test Strategy

• unit and integration suites for plugin/config/api/search/evaluator/writer behavior.
• regressions for malformed content, pagination anomalies, and write failures.
• deterministic stress runs for burst crawl and extraction-heavy workloads.
• release-profile benchmark runs for mapped scraper targets.

Performance Targets

• extraction-oriented scraper hot paths remain inside regression budgets.
• extraction/write-sensitive operations remain stable at p95/p99 envelopes.
• mapped benchmark manifests reach no-missing-case status for release gating.

Security / Reliability

• maintain strict URL and policy validation before fetch execution.
• preserve explicit failure signaling for fetch/parse/evaluate/write faults.
• enforce bounded behavior under high crawl pressure and noisy content.
• keep diagnostics actionable for production scraper incidents.
