Scope & context broadener · 5.4

A local typed-vocabulary traversal and review checklist. It preserves the intended concept paths, provenance, unknown vocabulary and persistent accept/defer/reject decisions without claiming a formal ontology reasoner.

Construction and scope

The invented Bracken Vale context vocabulary v1.0 contains 16 concepts and 16 individually referenced rules. Each rule has a source section, relation type and rationale. From each declared scope concept, depth-first traversal follows at most three directed rules without revisiting a node within a path. Targets already declared are excluded from suggestions. Multiple supporting paths stay visible.

A judgement is keyed to project, vocabulary version and the sorted supporting paths. An unchanged rejected suggestion stays rejected. If a new scope item adds a path, the previous decision/reason remains visible and the changed context explicitly requests review. Accepted factors expand the graph with their intermediate rule steps. Deferred/rejected factors remain in the exported checklist.

Unknown concepts use explicit extension records with no invented rules. The loaded drainage telemetry interface demonstrates this boundary. Project labels select context for a local assessment; they do not retrieve another app’s records.

Walkthrough

  1. Read the loaded station/temporary-work scope and visible unknown concept.
  2. Inspect Passenger accessibility, including R1 and R6, then Record context judgement with a reason.
  3. Reject ecology. Reviewing another suggestion does not reopen that rejection.
  4. Add bridge using Update starting scope. Its additional ecology path R12 makes the prior judgement visibly stale and retains the reason.
  5. Accept a factor and inspect the expanded typed graph/table; copy the full context report.

Verification and limits

node --test apps/scope-context-broadener/app.test.mjs covers six references: known paths and unknowns, rejection persistence, explicit reopening on a new path, accepted graph expansion/view invariance, unknown extension and atomic invalid review, retained-path import integrity and escaping.

This 16-concept vocabulary is intentionally bounded. It is newly authored fiction, not a rail standard or a complete ontology. Traversal cannot establish scope completeness, compatibility or permission. Compared with brainstorming it provides repeatable prompts, but expert judgement remains necessary. No formal reasoner, cross-app sync or live AI is claimed. Browser and publication checks belong to root integration.
