-- Migration 008: Formulaire settings + contact visibility
-- Adds site_settings key-value table for admin-configurable options
-- Adds show_contact column to authors table
-- Adds author_email + author_show_contact to views

-- ── 1. site_settings ─────────────────────────────────────────────────────────
CREATE TABLE IF NOT EXISTS site_settings (
    key   TEXT PRIMARY KEY,
    value TEXT NOT NULL DEFAULT '',
    updated_at DATETIME DEFAULT CURRENT_TIMESTAMP
);

-- Default formulaire settings:
-- access_type_interdit_enabled = 1 (Interdit is available in the add form)
-- access_type_interne_enabled  = 1 (Interne is available in the add form)
-- access_type_libre_enabled    = 0 (Libre is NOT yet available — next academic year)
INSERT OR IGNORE INTO site_settings (key, value) VALUES
    ('access_type_interdit_enabled', '1'),
    ('access_type_interne_enabled',  '1'),
    ('access_type_libre_enabled',    '0');

-- ── 2. show_contact on authors ────────────────────────────────────────────────
-- NOTE: SQLite has no IF NOT EXISTS for ALTER TABLE.
-- The migrate.sh script guards against re-running; ignore errors on existing DBs.
ALTER TABLE authors ADD COLUMN show_contact INTEGER NOT NULL DEFAULT 0;

-- ── 3. Rebuild views to expose author_email and author_show_contact ───────────
