Follow-up to the posture-grade-stability fix in 66433fe. Audited every
test that spawns a CLI and found more of the same class: tests running
HOME-scoped scanners (SKL/COL) or the CLAUDE.md cascade against the
developer's real ~/.claude instead of an isolated HOME.
Fixed (env: hermeticEnv()):
- posture.test.mjs — runs full posture (SKL/COL/cascade); twin of
the posture-grade-stability leak, masked only
because its asserts are structural/relative
- drift-cli.test.mjs — ACTIVE bug: the CLI wrote baselines into the
real ~/.claude during the run (pollution); now
isolated, and afterEach cleanup wrapped in
withHermeticHome so it looks in the same HOME
- token-hotspots-cli.test.mjs — scan-orchestrator run executes SKL/COL on
real HOME; TOK reads the HOME cascade
- accurate-tokens.test.mjs — TOK reads the HOME cascade (kept the
ANTHROPIC_API_KEY deletion)
Proven safe, left as-is (no HOME-scoped scan affecting assertions, no
HOME writes): post-edit-verify.test.mjs (fast-path early-returns only),
fix-cli.test.mjs (output byte-identical real vs empty HOME — fixable
findings are project-local HKV/RUL/SET, never SKL/COL),
lint-default-output (caller already uses withHermeticHome).
Suite 875/875, no snapshot drift. No test regressed under isolation,
confirming none had a hidden real-HOME dependency.

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.
