Two follow-up fixes after E16 + E17 landed:
1. foldHomoglyphs ASCII fast-path
- scanForInjection calls foldHomoglyphs on every scan (raw + normalized).
- Pre-fix: NFKC normalization runs unconditionally, even on pure
ASCII inputs where it's a no-op.
- Result: benchmark.test.mjs timed out at 120s on the full suite.
- Fix: charCodeAt sweep for >=128, short-circuit return s when
all ASCII. NFKC and HOMOGLYPH_MAP iteration only run when
non-ASCII chars are present (the actual attack case).
- Verified: benchmark.test.mjs passes within timeout.
2. Attack-scenario UNI-003 expectation
- Pre-E16: "Homoglyph Cyrillic-Latin mixing" payload triggered only
a MEDIUM "obfuscation present" advisory (exit 0, stdout match
"MEDIUM").
- Post-E16: the same payload is folded to Latin BEFORE pattern
matching, so it now matches CRITICAL "ignore previous instructions"
and blocks (exit 2).
- This is the intended v7.2.0 behavior — not a regression. Updated
expectation: exit_code 2, stdout_match "block". Renamed scenario
to "now blocked via E16 fold, v7.2.0".
Suite: pre-compact-scan flake remains (perf-budget under load,
passes isolated). All other tests green.
Add /ultraresearch-local for structured research combining local codebase
analysis with external knowledge via parallel agent swarms. Produces research
briefs with triangulation, confidence ratings, and source quality assessment.
New command: /ultraresearch-local with modes --quick, --local, --external, --fg.
New agents: research-orchestrator (opus), docs-researcher, community-researcher,
security-researcher, contrarian-researcher, gemini-bridge (all sonnet).
New template: research-brief-template.md.
Integration: --research flag in /ultraplan-local accepts pre-built research
briefs (up to 3), enriches the interview and exploration phases. Planning
orchestrator cross-references brief findings during synthesis.
Design principle: Context Engineering — right information to right agent at
right time. Research briefs are structured artifacts in the pipeline:
ultraresearch → brief → ultraplan --research → plan → ultraexecute.
