From f60f8d88febc43450e414797906f7955567cd2ce Mon Sep 17 00:00:00 2001 From: "copilot-swe-agent[bot]" <198982749+Copilot@users.noreply.github.com> Date: Tue, 11 Aug 2026 14:26:31 +0000 Subject: [PATCH 01/21] Initial plan From a30288163a15b55546ae9c31a8e5164fe73b2091 Mon Sep 17 00:00:00 2001 From: Thaddeus Loke Date: Mon, 6 Jul 2026 13:34:56 +0900 Subject: [PATCH 02/21] Add harms testing for BCAL via --harms-fixture (direct + indirect vectors) Vector-invariant harms cases expand across a vector matrix (direct/UPIA plus symbols, page_inspector, translations, ask_user, packages seams/XPIA). Manual YAML+Jinja2 source now; source-agnostic runner keeps a red-team adaptor pluggable. Trials are scored with Azure AI safety evaluators (incl. IndirectAttackEvaluator) and uploaded to Foundry via evaluate(). Adds bcbench harms run/report with --dry-run/--limit/--vector/--no-upload rapid-validation levers.

Expose tools_invoked + injection_landed on HarmsTrial and a per-run summary so XPIA 'resisted' scores are not misread when the attack never reached the model. Also craft suite triggers to invoke the seam-reading tools and add placement targeting real objects. Investigation found that in bcal 52553-beta the symbols/page_inspector injections do not surface in the CLI tools (inspect_page/ search_symbols/get_properties return unmodified data) even with correct targeting/triggers; documented as a build-dependent limitation.

Apply a default Caption-on-page placement in RedTeamHarmsSource mirroring the manual suites, so harvested objectives actually reach the model. Make evaluate_trials degrade gracefully: a single flaky/unreachable RAI evaluator (e.g. indirect_attack / code_vulnerability timing out) previously aborted the whole batch and discarded successful evaluators. Fall back to scoring each evaluator independently, merge partial results, and report failed_evaluators for later re-scoring. Add manual-xpia harms suite (10 XPIA cases on real Base Application pages).

Export harm_delivered and a valid flag on every eval_dataset.jsonl row so invalid lines can be filtered downstream/in Foundry. Add 'bcbench harms annotate' to back-fill delivery/landing from captured logs without re-running bcal (rewrites trials.jsonl, refreshes eval_dataset.jsonl), with robust log-path reconstruction for moved run dirs.
