Wave 2 / Step 6 of the remediation plan.
Organic personal-post A/B tests gather a handful of posts per variant — far below
the volume a significance test needs — so the tool must not imply statistical
significance:
- Rename the results-table "Significant?" column to "Directional?" and define it
as "clears the ~20% minimum-meaningful-difference AND points the same way across
most posts" — a direction to test further, not a significant result.
- Reword the "20% significance rule" to a minimum-meaningful-difference effect-size
heuristic (explicitly NOT statistical significance).
- Replace the "3 = Medium, 5+ = High" confidence ladder with a directional-only
confidence section: treat every result as directional (not significant) given
realistic volume is well under ~50 conversions/variant; name a direction, not a
winner.
The 20% minimum-meaningful-difference threshold itself stays — it is a legitimate
effect-size heuristic; only the significance framing was the false claim.
Verify: no "Significant?"/"20% significance" remain; "directional" present;
structural lint 0 failed.

BREAKING CHANGE: the marketplace slug, the agent namespace
(linkedin-studio:<agent>), and the runtime state-file path
(~/.claude/linkedin-studio.local.md) all change. Reinstall required;
existing state migrated in place (post metrics, streak, history preserved).
The /linkedin:* commands are unchanged — the command namespace is set
per-command in frontmatter and was always independent of the plugin slug.
Functionality is byte-identical to v2.4.0; this release is pure identity.
- dir + manifests: plugins/linkedin-studio + plugin.json + root marketplace.json
- agent namespace updated in commands/newsletter.md (only functional invoker)
- state path updated in 4 hook scripts + topic-rotation prompt + state template
- catch-all skill dir renamed skills/linkedin-studio (5 functional skills unchanged)
- docs + version bump to 3.0.0 across README badge, CHANGELOG, root README/CLAUDE.md
- historical records (CHANGELOG past entries, docs/ build artifacts,
config-audit v5.0.0 snapshots) intentionally retain the old slug

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.
