The Company entity represents a target organization within the job search pipeline. It serves as the parent container for roles (Jobs) and tracks high-level metadata such as domain expertise, business model, and screening status. Companies are persisted as Markdown files within the companies/ directory of the user's vault.

Data Model

The Company model is synchronized between a Rust struct for backend processing/persistence and a TypeScript interface for the Svelte frontend.

Rust Struct (src-tauri/src/company.rs)

The Rust Company struct includes both persistent fields (from YAML frontmatter) and derived fields calculated at runtime, such as due_for_check and screening.

src-tauri/src/company.rs#16-35

Field Type Description
slug String Unique identifier derived from the filename.
name String Display name of the company.
domain Vec<String> List of functional/industry tags (e.g., fintech, security).
due_for_check bool Derived: true if status is active and last_checked is > 3 days old.
screening Option<String> Derived: dealbreaker or caution based on domain screening rules.
notes String The Markdown body of the note.

TypeScript Interface (src/lib/company.ts)

The frontend interface mirrors the Rust struct to ensure type safety across the Tauri IPC bridge.

src/lib/company.ts#3-21

Statuses and Screening

Companies follow a simple lifecycle defined by the status field:

  • active: Currently being monitored for new jobs.
  • paused: Monitoring temporarily disabled.
  • exhausted: No relevant roles found after thorough checking.
  • removed: Soft-deleted (file remains in vault but hidden from main views).

src-tauri/src/company.rs#10

Screening Flags: The screening field is derived by comparing the company's domain tags against the user's domain screening configuration.

  • dealbreaker: If any domain matches a "dealbreaker" rule, the company is flagged immediately.
  • caution: If any domain matches a "caution" rule (and no dealbreakers exist).

CRUD Operations & Tauri Commands

Company data is managed via Tauri commands that perform atomic updates to the Markdown files. All writes are routed through write_note in note.rs to ensure the file watcher can distinguish app-driven changes from manual user edits.

Command Flow: Natural Language to Code

This diagram maps user actions in the UI to the underlying Rust logic and persistence layer.

Key Functions

Function Location Purpose
list_companies src-tauri/src/company.rs Scans the companies/ dir, parses every .md file, and returns a list of Company structs.
update_company_field src-tauri/src/company.rs Updates a single scalar frontmatter field (e.g., stage) using note::set_frontmatter_field.
set_company_list_field src-tauri/src/company.rs Specifically handles Vec<String> fields like domain or business_model using YAML flow sequences ([...]).
set_company_notes src-tauri/src/company.rs Replaces the Markdown body (everything after the frontmatter) using note::set_body.

Frontend State Management

The companiesStore manages the global state of all loaded companies using Svelte 5 runes ($state).

companiesStore (src/lib/companies.svelte.ts)

The store acts as the single source of truth for the UI, handling initial loads, vault selection, and optimistic updates via the apply helper.

src/lib/companies.svelte.ts#13-28

  • Reactivity: When a command like updateField is called, it awaits the result from the backend (the re-parsed Company object) and passes it to apply(), which replaces the existing object in the $state array.
  • Persistence: The vaultPath is persisted in localStorage to maintain context across sessions.

src/lib/companies.svelte.ts#24-26src/lib/companies.svelte.ts#76-78

View Logic (src/lib/companyView.ts)

Filtering, sorting, and searching are decoupled from the store into a pure utility module. This allows for complex UI logic (like grouping by domain or relevance ranking) without mutating the underlying data.

  • Search Tiers: The searchCompanies function implements a tiered ranking system for search results.

  • Tier 0: Name prefix match.

  • Tier 1: Name substring match.

  • Tier 2: Domain name match.

  • Tier 3: Domain alias match.

  • Tier 4: Notes body match (includes a notesSnippet around the hit).

Data Flow: Update Sequence

This diagram illustrates the "round-trip" data flow when a user updates a company field, such as changing the status.
