# Field guide build — tools

The distinct tools record for Field guide build. This page is proposal-only.

Status: **proposed**Lifecycle: **candidate**

## Record status

**Record ID**: project:field-guide-build

**Parent lifecycle**: candidate

**Page lane**: app_features

**Lane lifecycle**: proposed

**Owner**: Not separately recorded

**Owner role**: Not separately recorded

**Owner status**: Not separately recorded

**Qualification result**: NOT RUN · held for evidence and human review

**Working browser surface:** [Project templates & workflows — overview](<https://guthlabs.ai/labs.html#templates-workflows>) — Create a local project from this template and validate its forms. This route is local-only; provider, credential, database, customer, publication, deployment, and production effects remain held.

## Authoritative app_features lane tools and interfaces

### Canonical tools-page assignments

- **Notebook Projects** (interface · required) — Owns project grouping, project lifecycle, links, and local project state.

- **Notebook Field Guides** (interface · required) — Owns composition and inspection of source-backed guide procedures.

- **Notebook To-dos** (interface · required) — Owns task completion, dueAt, priority, recurrence candidate, tags, and review signals.

- **Notebook Agenda** (interface · required) — Displays source-bound deadlines, workbacks, and draft schedule conflicts without external writes.

- **Notebook Approvals** (interface · required) — Owns human review decisions and receipts.

- **PointGuard** (interface · required) — Projects current work, next action, deadlines, linked records, and held effects across the app family.

- **Notebook Search** (interface · required) — Finds local records while respecting private and held visibility partitions.

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

[date-duration-calculatorrequired · Calculate elapsed and remaining duration between project milestones and target review dates.](<https://guthlabs.ai/docs/instruments/date-duration-calculator/>)[countdown-days-until-timerrequired · Display a local countdown to the next review or maintenance deadline.](<https://guthlabs.ai/docs/instruments/countdown-days-until-timer/>)

An instrument listed only for another lane does not become a tools-page assignment.

## Use boundary

- A source hash or locator may be absent, stale, or mismatched; display the limitation instead of implying provenance.

- A workback may appear precise even when task durations are estimates; label all user-entered estimates and assumptions.

- A field guide may be mistaken for a qualified operational or safety procedure; show scope, exclusions, uncertainty, and non-qualification language.

- Date and timezone errors can shift deadlines; require explicit timezone labels and show the normalized local date-time.

- Completed work may be invalidated by later source revisions; surface revision drift and request review.

- Private notes, files, and approval records must not leak into public or customer-facing contexts.

- Instrument errors, errata, or unsupported inputs must produce recoverable failure states and preserved receipts.

- PointGuard context may become stale; show last-updated time and a refresh/recompute action.

- Local persistence may be cleared or unavailable; show unsaved-state warnings and an export-held notice without claiming backup.

- External effects remain held; never represent a draft message, schedule, publication, or qualification as completed.
