From 827ef9c1a0367ca9ed3a49cfcdf9796063a0c27f Mon Sep 17 00:00:00 2001 From: tegwick Date: Thu, 14 May 2026 23:24:48 +0200 Subject: [PATCH] feat(WP-0003c): context adapters, first ActivityDefinition, full test suite MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit T51: ContextResolver ABC + CONTEXT_RESOLVER_REGISTRY; resolve_context activity updated to dispatch via registry (warns + binds {} on failure, never aborts run). T52: RepoScopingContextResolver with 5-min in-process cache. T53: StateHubContextResolver (no cache) for domain_summary and repo_sbom_status. T54: activity-definitions/weekly-sbom-staleness.md (Monday 09:00 Berlin, cron trigger, flag-stale-sbom rule at >30 days) + tasks/sbom-rescan.md template. T55: 51 parametrized evaluator tests — all whitelisted operators, unsafe expression rejection, empty condition, missing attribute, nested context access. T56: 15 executor safety tests — UntrustedFieldError, object-type rejection, injection fixture, LLM retry on bad JSON, review_required field. T57: 6 integration tests — parses real definition, evaluates rule per-repo (stale/fresh boundary), emits via NullSink, verifies spawn log entries.
