Status: **proposed**Lifecycle: **candidate** ## Record status **Record ID**: field-guide:course-routes **Parent lifecycle**: candidate **Page lane**: tools **Lane lifecycle**: proposed **Owner**: Socrates **Owner role**: Not separately recorded **Owner status**: Not separately recorded **Qualification result**: NOT RUN · held for evidence and human review **Working browser surface:** [Field guides — documentation]() — Inspect the guide and persist local checkpoints. This route is local-only; provider, credential, database, customer, publication, deployment, and production effects remain held. ## Authoritative tools lane tools and interfaces ### Canonical tools-page assignments - **Notebook Field Guides** (interface · required) — Owns the procedure, prerequisites, bounded steps, instrument links, failure states, and acceptance tests. - **Notebook Notes** (interface · required) — Stores source-labelled explanations, learner questions, assumptions, and uncertainty notes. - **Notebook Files** (interface · optional) — Keeps local references to syllabi, worksheets, or source material beside the calculation without implying hidden upload or protected storage. - **Notebook To-dos** (interface · required) — Tracks human review, source reconciliation, and explicit due dates without implying automated completion. - **Notebook Approvals** (interface · required) — Separates a locally reviewed interpretation from an unreviewed proposal and preserves the receipt. - **PointGuard** (interface · optional) — Carries the current lesson context across Notebook surfaces; it is not the canonical owner of calculations or course records. - **Notebook Search** (interface · optional) — Finds related local notes, receipts, and prior study records while respecting visibility boundaries. - **Scientific Calculator** (provider · optional) — Catalog instrument for transparent arithmetic, powers, roots, and basic quantitative checks when a more specific instrument is unnecessary; must not be treated as a source or proof. - **Unit & Dimensional Analysis Converter** (provider · optional) — Checks unit conversions and dimensional consistency in quantitative lessons; must not validate the underlying model or source assumptions. - **Statistics Suite (descriptive stats)** (provider · optional) — Summarizes learner-collected or source-provided datasets for instruction; must not establish causation, generalize beyond the supplied data, or replace study-design review. - **Date & Duration Calculator** (provider · optional) — Builds lesson schedules, study intervals, and workbacks from explicit dates; must not imply calendar-provider writes or automatic reminders. Only the page's admitted lane is rendered as an assignment. Other lane inventories remain source records but are not merged here. Tool kind and required/optional status are preserved. ## Authoritative lane instrument assignments ### Canonical tools-page assignments [scientific-calculatoroptional · Use for reproducible arithmetic, powers, roots, and intermediate checks in a lesson receipt; do not use as evidence, a source comparison authority, or a substitute for a domain model.]()[unit-dimensional-analysis-converteroptional · Use to convert declared units and expose dimensional mismatches; do not use to decide whether a formula, measurement, or source claim is valid.]()[statistics-suite-descriptive-statsoptional · Use for descriptive summaries such as mean, median, spread, and counts of an explicitly bounded dataset; do not use for causal claims, diagnosis, qualification, or unsupported population inference.]()[date-duration-calculatoroptional · Use to calculate lesson durations and review workbacks from supplied dates; do not use for external calendar changes, provider scheduling, or deadline guarantees.]() An instrument listed only for another lane does not become a tools-page assignment. ## Use boundary - Using a calculator output as if it were evidence or a sourced fact. - Selecting a convenient instrument whose assumptions do not match the lesson. - Unit mismatch, transcription error, premature rounding, or hidden spreadsheet state. - Treating descriptive statistics as causal, predictive, medical, legal, financial, or safety advice. - Turning a draft schedule into a provider-backed booking or deadline guarantee. - Overstating a source comparison when the sources use different definitions, populations, or measurement methods. - Losing provenance when copying an output into a learner-facing note. - Accessibility failures from color-only review states, unlabeled fields, or inaccessible result tables. - Allowing an Agent to approve its own consequential interpretation without human review. - Confusing a named route or native surface with a deployed or connected feature. ## Sources and evidence These pointers bind the page to evidence. They do not grant authority or collapse verification into deployment. - `source_record:field-guide:course-routes` - `agents/index.html#socrates` - `Observed native contract: Notebook fieldGuide collections and lifecycle` - `Observed native contract: Notebook records, provenance, revisions, and source SHA-256` - `Observed native contract: Notebook todos with due dates, completion state, tags, and review signals` - `Observed native contract: PointGuard cross-app context boundary` - `App route: /app/notebook/field-guides/` - `App route: /app/notebook/notes/` - `App route: /app/notebook/files/` - `App route: /app/notebook/to-dos/` - `App route: /app/notebook/approvals/` - `App route: /app/notebook/search/` - `Allowed instruments: scientific-calculator` - `Allowed instruments: unit-dimensional-analysis-converter` - `Allowed instruments: statistics-suite-descriptive-stats` - `Allowed instruments: date-duration-calculator`
