v1.3.26 — Original-app quirk decisions

Original-app quirks now have focused preserve, improve or defer guidance. Reconstruction decisions link observed evidence, user goals, affected consumers and acceptance, while keeping inferred intent and intentional differences separate.

• Preserve required file/protocol compatibility; improve within authorized goals after checking dependencies; defer visibly with an unresolved question or revisit trigger.
• Retain scope, useful-first-slice priorities and mode boundaries without compulsory per-quirk approval gates. Planning alone does not authorize implementation.
• Add a worked mixed-profile example and 14 bounded same-agent manual scenarios, clearly separated from executable tests. Two selection-checker regressions challenge unchanged pin ordering and hidden-pin retention.

Installer/updater/integration, consent, safe paths, recovery, historical oracles and CI safeguards are unchanged. No new dependency, model API, agent, paid service or scheduler. Local denied full-suite preflights remain incomplete; supported public CI and exact artifact checks are required before publication. Existing host sessions may need to reload the updated skill.
