triangulate

First ingest into the triangulate project. Stable summary of the Phase 0 disconfirming experiment that ran 5 topics today across 3 editorial registers (political-news, financial-thesis, serious-history feature) and a 0%-to-95% vault-substrate range. Protocol quality stayed flat across that range; Q1-Q4 all cleared.

• Created transferable-f3-misinterpretation-patterns (concept): five recurring F3 patterns surfaced across Phase 0; inputs to the Misinterpretation Editor agent's prompt when Phase 2 builds it.
• Created editorial-register-classes (concept): three validated register classes with conventions for each; inputs to the House-Style Editor's exemplar corpus.
• Created vault-two-functions-substrate-and-methodology (concept): the architectural distinction Topic 4 surfaced (vault-as-substrate vs vault-as-methodology); directly informs Phase 1 design of packages/vault/ typed reader.
• Created mechanism triangulate-4-phase-application-protocol (4 steps): the validated protocol Phase 2 codes — Reporter → Parallel Checkers → Render-with-House-Style + Sequential Gates → Audit Log.
• Updated index.md: all new entries added across Concepts, Mechanisms, and Sources sections.

Cross-links established to vault meta-docs: vault/_meta/JOURNALISTIC_STANDARDS.md (the standard the protocol enforces), vault/_meta/SOURCE_RELIABILITY.md (the tracker the protocol consults during fetches), vault/_meta/RESEARCH.md (the typed page schemas).

Scaffolded the triangulate project as the brain-side companion to the AI-assisted investigative-journalism newsroom at ~/Projects/personal/triangulate/. This is the meta-research workspace per the Plan — journalism methodology, case studies, source-monitoring infrastructure, and newsroom operational decisions and post-mortems accumulate here.

• Created SCOPE.md (topics in/out of scope; boundaries with threads/journalism, threads/politics, threads/artificial-intelligence, projects/career).
• Created index.md (empty catalog with pointer to the application code repo).
• Created log.md (this file).
• Created sources/ (with .gitkeep).
• Created wiki/entities/, wiki/concepts/, wiki/mechanisms/, wiki/questions/ (all empty, .gitkeep).

Phase 0 of the triangulate experiment ran 5 topics earlier today across three editorial registers (political-news on AB 2624 and MN childcare freeze and PA Medicaid; financial-thesis on TSMC-Intel re-rate; serious-history feature on the Bronze Age Collapse). Findings and articles live in the application repo at ~/Projects/personal/triangulate/. Once those findings stabilize, summaries and lessons should be promoted as sources into this project so the operational learning compounds in the vault.

Cross-references for first-pass ingest material that already exists:

• vault/_meta/JOURNALISTIC_STANDARDS.md — operational checklist already shipped; refinements happen here.
• vault/_meta/SOURCE_RELIABILITY.md — fetchability tracker already shipped; refinements happen here.
• vault/threads/journalism/ — adjacent thread covering practitioner codes and peer-reviewed journalism research; most journalism-methodology material primarily lands there with multi-context promotion here when operationally actionable for the newsroom.

Next expected operation: first ingest once initial sources are added (likely a Phase 0 retrospective summary).
