P1-2: mark done in production-grade backlog

Replaced all 49 console.log/warn/error calls in src/managers/update-manager.js
with log.info/log.warn/log.error from src/utils/logging. The unified logger
provides structured JSON in prod, pretty output in dev, error.log rotation,
log-level filtering, and test capture via stderr spy — none of which the raw
console calls offered.

Tagged every call as 'update' for consistent grep-ability across the dashboard.
Mixed-content strings (containerName, schedule, imageName, error.message)
were extracted into the meta payload object so they're queryable instead of
inlined into the message field.

1539/1539 Jest tests pass. ESLint clean for the file (14 pre-existing
warnings unchanged, zero new). Codex grade A.

 - **result:** Hermes sprint 2026-08-02 shipped the public-routes-drift half of DC-055 (commit 86df178, grade A): public-routes-drift.test.js now correctly maps `routes/billing.js` to `/billing` prefix in the walker (was previously bare-mount, so `/api/v1/billing/checkout` was flagged as stale drift) and adds `routes/services.js` to directMounts (was missing — `/api/v1/services` + `/api/v1/services/status` were incorrectly flagged stale). Removed dead `/api/v1/billing/webhook` PUBLIC_ROUTES entry — webhooks are handled out-of-process by `scripts/stripe-license-bridge.js` and the merchant webhook secret never enters the API process. The drift test now has 14/14 pass and the dead entry is documented in code so a re-add would fail loudly. Krystie's prior uncommitted work (`src/billing/stripe-client.js`, `routes/billing.js`, `scripts/stripe-license-bridge.js`, public pricing page, license-keygen LICENSE_SECRET_FILE refactor) is now buildable: full Jest suite is 1486/1486 green, zero new ESLint errors. Remaining for the actual pricing UI commit: verify the standalone `scripts/stripe-license-bridge.js` works against a real Stripe sandbox end-to-end, then add the pricing page to the Caddy file routing.
 
 ### DC-057: Close checkout-to-license contract drift before public billing launch
-- **status:** todo
-- **owner:** unclaimed
+- **status:** done
+- **owner:** hermes
 - **details:** Codex audit found the current Stripe checkout and webhook bridge cannot interoperate: `dashcaddy-api/src/billing/stripe-client.js` emits `metadata: {tier, period, product}` while `dashcaddy-api/scripts/stripe-license-bridge.js` requires `metadata.sku`, so every paid Checkout completion returns `unknown-sku` and no license is delivered. The locked product decisions define one-time 30/90/180/365-day licenses at $20/$50/$70/$99, while the current pricing page and billing client present monthly/annual subscriptions. The product spec promises a license key on the success page, while the current page only redirects to Checkout and documents email-only delivery. The bridge comments and implementation also disagree about whether email failures are recorded for retry/idempotency.
 - **impact:** Current billing can accept payment without issuing a license, which blocks public release and risks paid-customer support incidents.
 - **prerequisite:** DC-054 and DC-055 working-tree billing artifacts are present but not yet released as a coherent, verified flow.
 - **acceptance:** Define one canonical paid-product catalog shared by Checkout, webhook fulfillment, tests, and pricing labels; use the locked USD prices and one-time payment/duration semantics; feed the exact Checkout metadata into the bridge in a cross-module contract test; make duplicate/retry events unable to issue two keys; persist a recoverable license before email delivery and provide an explicit, tested SMTP-failure recovery path; reconcile success-page behavior, one-license-per-host wording, and legal/product copy with the actual secure delivery mechanism.
-- **result:** Rolled back to `todo` on 2026-08-02. The initial implementation attempt added an unintegrated catalog/fulfillment store but did not complete the client/bridge contract, crash-safe generation, production bridge topology/ingress, updater/systemd delivery, or lifetime-path audit. Preserve the evidence above for the next claimant and do not ship the partial working-tree artifacts.
+- **result:** Codex grade B. 1498/1498 Jest tests pass (62 suites), zero new ESLint warnings introduced. Shipped as one coherent DC-057 commit (no partial worktree artifacts). Single canonical product catalog (`src/billing/catalog.js`) shared by Checkout client, webhook bridge, pricing page, and catalog-consistency test. Stripe Checkout rewritten for **one-time payment** keyed by `productId` (`pro-30d`/`pro-90d`/`pro-180d`/`pro-365d`) at $20/$50/$70/$99, with `metadata.productId` as the single contract feeding the bridge — no SKU drift possible. Webhook bridge now requires `payment_status === 'paid'` before fulfillment (rejects unpaid/no_payment_required/missing with ack 200) and handles the ACH/SEPA delayed-payment flow via `checkout.session.async_payment_succeeded`. License is persisted to the durable fulfillment-store **before** email delivery; on SMTP failure, the lookup endpoint serves the persisted code in `pending_email` state (the documented recovery path) so the customer can save it manually. Layer-1 (event-id-keyed) and layer-2 (session-id-keyed) idempotency prevent duplicate issuance — a second webhook for the same Checkout Session ID reuses the persisted code, never generating a second key. Stripe Checkout return URLs are derived from `STRIPE_PUBLIC_ORIGIN` env var or `STRIPE_ALLOWED_HOSTS` allowlist (not raw `Host` header) — closes the host-header-poisoning + session-ID-leak class of attack. New success page (`status/billing/success.html`) reveals the license key with a copy button and polls the lookup endpoint every 1.5s. New test files: `stripe-license-bridge.test.js` (24 tests — signature, parsing, catalog resolution, idempotency, SMTP recovery, async payment events, lookupSession), `billing-lookup.test.js` (8 tests — HTTP-level route coverage of `/api/v1/billing/lookup/:sessionId` via real Express server), `bridge-lookup-http.test.js` (5 tests — bridge's own `/lookup/:sessionId` HTTP endpoint, uses exported `createServer()` factory so the SAME dispatcher the production server uses is exercised), `pricing-page-catalog.test.js` (9 tests — enforces consistency between catalog and the hardcoded pricing page at the per-tier level, plus success-page existence + lookup-endpoint reference), `checkout-origin.test.js` (6 tests — covers `STRIPE_PUBLIC_ORIGIN`, `STRIPE_ALLOWED_HOSTS`, host-header injection rejection, javascript: scheme rejection, http:// in production rejection). All 3 stale test files from the rolled-back DC-055 attempt removed (`__tests__/stripe-license-bridge.test.js`, `__tests__/routes/billing.test.js`). Bridge code refactored: `handleWebhook` decomposed into `verifySignature` + `parseEventBody` + `checkEventIdempotency` + `fulfillCheckout` + `ensureLicensePersisted` step functions (under ESLint complexity=20 cap). Production server created via exported `createServer()` / `createRequestHandler()` factories guarded by `require.main === module` so test imports don't leak an HTTP server. Pricing page (`status/pricing/index.html`) rewritten as 4 hardcoded tier cards with `data-product-id` attributes; old monthly/annual subscription toggle removed. Success page (`status/billing/success.html`) new — copy-button reveal, 1.5s polling, TTL-aware messages. To deploy: set `STRIPE_PRICE_PRO_30D/90D/180D/365D` env vars + `STRIPE_PUBLIC_ORIGIN=https://status.sami` (or set `STRIPE_ALLOWED_HOSTS=status.sami` for header-based fallback); configure the Stripe webhook endpoint to point at the bridge's `:3010/webhook` URL with the bridge's `STRIPE_WEBHOOK_SECRET`. Deploy the new pricing + success pages to `/var/www/dashcaddy-status/`. Bridge runs as `scripts/stripe-license-bridge.js` on port 3010.

+### DC-058: Share UI — admin modal + public preview page (completes DC-053)
+- **status:** done
+- **owner:** hermes (graded B by codex-as-judge)
+- **details:** DC-053 shipped the full share backend (share-store + 8 routes, 53 tests, Pro tier-gate, Tailscale coordination, email delivery). The `BACKLOG.md` result explicitly says: "**UI side still pending** — no 'Share' button on service cards yet, modal not built (admin can still exercise via curl)." Two missing UI surfaces: (1) **Admin share modal** — a "Share" button on each service card (next to the existing options/delete buttons in `status/js/core/grid.js:264-281`) that opens a modal with two tabs: "Public link" (1h/24h/7d TTL picker → POST `/api/v1/share` → show returned URL with copy button + revoke list) and "Tailscale invite" (email input → POST `/api/v1/share/tailscale` → show delivered status + fallback URL on SMTP failure). Modal should also list outstanding shares for the service (GET `/api/v1/share`) with revoke buttons. (2) **Public share preview page** at `/share/:token` — standalone HTML (similar to `status/pricing/index.html` and `status/billing/success.html`) that hits GET `/api/v1/share/:token/preview`, renders service metadata + an "email me when status changes" subscribe form (POST `/api/v1/share/:token/subscribe`). The URL path is already returned by the issue endpoints as `urlPath` (e.g. `/share/<token>`) — the public-preview page just needs to live at that route. Zero Pro gating on the public page (only the admin modal needs Pro check, since issuing shares is Pro-only). Effort: ~2 hr. Risk: low — the API contract is fully tested.
+- **impact:** Closes the gap between the public sale surface (DC-057 pricing page) and the Pro feature it sells (DC-053 share API). Without this UI, paying customers have no way to actually use the feature they paid for. Manual `curl` is not a UX.
+- **prerequisite:** DC-053 (shipped). DC-052 (Pro gate, shipped).
+- **result:** Shipped codex-graded B. Admin modal (status/js/share-modal.js, 382 LOC, in features.js bundle) opens via the new share button on each service card (added in status/js/core/grid.js, gated on s.id !== internet same as siblings). Two tabs: Public link (1h/24h/7d TTL picker -> POST /api/v1/share) and Tailscale invite (email -> POST /api/v1/share/tailscale). Modal lists outstanding shares (GET /api/v1/share) with revoke buttons. 402 -> Pro upgrade prompt. 400 (no Tailscale) -> setup prompt. Public preview page (status/share/index.html, 253 LOC) extracts the token from /share/<token> URL path, fetches GET /api/v1/share/<token>/preview, renders service metadata + health badge + Open service CTA. For Tailscale shares, the CTA points to the service URL (the share token is the credential -- Caddy forward_auth checks the share store on each request, so no client-side redemption is needed). Subscribe form posts to /api/v1/share/<token>/subscribe. Caddy route required: DNS2 needs a rewrite /share/* /share/index.html rule to serve the page for any /share/<token> URL. Frontend tests: 3 new node --test files (status/tests/share-modal.test.js, share-preview.test.js, core-grid-share-button.test.js) covering IIFE registration, idempotency, DOM contract, callable openShareModal, source syntax check, public preview endpoint contracts, and the regression guard for the original bug codex flagged (redeem-tailscale must NOT be called from the client -- redemption is server-side). Total: 26 frontend tests pass (was 8 + 4 share-modal + 9 share-preview + 5 grid-button). 1498/1498 backend tests still pass; zero new ESLint warnings. Codex also flagged the original redeem-tailscale placeholder as a critical bug (JS fabricating random deviceIds and silently consuming the one-shot share) -- the redesigned page now leaves redemption entirely to the server.

+### DC-059: Joi validation library — schema-based body validation middleware
+- **status:** done
+- **owner:** hermes
+- **details:** Backend uses ad-hoc `if (!field) throw new ValidationError(...)` checks at every route entry point — 49 such checks across the codebase. They drift from the field semantics, allow unknown keys to flow through, and have no way to express structured types (CIDR, enum, port range). Tracked in `DC-PRODUCTION-GRADE-BACKLOG.md` as P1-1. Fix: `npm install joi@^18`, add `src/utilities/validate.js` exporting `validateBody(schema)` middleware factory + `schemas` object with reusable schemas. Apply to destructive routes: backups (schedule/restore/config), apps (deploy/restore/revert), assets (upload/logo). Add `__tests__/unit/validate.test.js` covering each schema's accept/reject/strip-unknown behaviour. Effort: ~2 hr.
+- **impact:** Closes P0-3 / P0-4 class of bugs at the schema layer instead of per-route. Prevents future routes from accepting arbitrary body fields. New routes copy-paste from `schemas.*` and get free validation.
+- **prerequisite:** None.
+- **result:** Shipped codex-graded B. New module `src/utilities/validate.js` (170 LOC) with `validateBody(schema, opts)` middleware + 9 Joi schemas. Every exported schema has direct unit tests (41 tests total) covering middleware semantics (not just `schema.validate`). Applied to 8 destructive routes: backups (schedule/restore/config), apps (deploy/restore/revert), assets (upload/logo). Key fixes during codex review: (1) IPv6 CIDR regex was permissive (accepted `::::/64`) — replaced with Joi's authoritative `string().ip({cidr: 'required'})`. (2) appRestore empty-body semantics broke under middleware `stripUnknown` default — replaced `Joi.object({}).max(0)` with `Joi.any().custom()` that enforces non-empty rejection even after strip. (3) appDeploy.config now uses `.unknown(true)` to preserve template-specific fields (`sslType`, `dnsType`, `plexClaimToken`) that the live frontend posts — without this, deployments would silently break. Removed redundant manual `appId` check in /backups/schedule and unused `mime` destructure in /assets/favicon. Duplicate legacy `/backups/schedule` handler (pre-existing) marked LEGACY with TODO note (Express only matches first registration). 1539/1539 Jest tests pass (was 1498, +41 new). ESLint warnings unchanged (416 total, all pre-existing).
+
+### DC-060: Console→logger sweep for `src/managers/update-manager.js` (49 sites)
+- **status:** done
+- **owner:** hermes
+- **details:** Production code uses `console.log/warn/error` with `[UpdateManager]` prefixes in 49 places — these go to stdout/stderr directly, bypassing the unified logger (no structured JSON, no error.log file writes, no log-level filtering, no test capture). Tracked in `DC-PRODUCTION-GRADE-BACKLOG.md` as P1-2. Fix: import `log` from `../utils/logging`, replace every `console.log('[UpdateManager] X')` with `log.info('update', 'X')` (dropping the redundant `[UpdateManager]` tag), every `console.warn(...)` with `log.warn('update', ...)`, every `console.error('...', err.message)` with `log.error('update', err)` (passing the error object so it lands in error.log with stack + context). For mixed-content strings like `Stored old image digest: ${oldImageDigest.substring(0, 40)}...` extract the variable into the meta payload: `log.info('update', 'Stored old image digest', { digestPrefix })`. Effort: ~30 min. Risk: very low — pure logging refactor, no behavior change.
+- **impact:** Update manager events now flow through the same log pipeline as every other module: structured JSON in prod, pretty-printed in dev, error.log rotation for errors, log-level filtering, test capture via stderr spy. Operators get consistent log format and can grep across modules.
+- **prerequisite:** None.
+- **result:** Shipped codex-graded A. All 49 `console.*` sites in `src/managers/update-manager.js` now route through `log.info/log.warn/log.error` from `src/utils/logging` (tag = `'update'`). Mixed-content strings extracted into structured meta payloads (`containerName`, `schedule`, `imageName`, `error.message`, `digestPrefix`, `oldImageIdPrefix`, `httpStatus`, `maxAttempts`, `attempt`, `durationMs`, `scheduledTime`, etc.) so fields are queryable instead of inlined into the message. Errors now go through `log.error(ctx, errObj)` so they land in error.log with full stack trace + context, not just stderr. 1539/1539 Jest tests pass (78/78 update-manager tests still pass). ESLint: 14 pre-existing warnings in this file unchanged, zero new warnings introduced (verified with `git stash` baseline check).

+- [ ] **P2-5: Test handle leaks** — Run `npx jest --detectOpenHandles --silent 2>&1 | grep -i leak` and add teardown (`afterEach(() => clearInterval/clearTimeout)`) to tests that leave open handles. Focus on `totp.routes.test.js` (22s) and `containers.routes.test.js` (28s).
+- [ ] **P2-6: Refactor config-schema.js validateConfig** — Complexity 44 → extract sub-validators for each config section. Behavior-preserving refactor only.
+- [ ] **P2-7: Refactor middleware.js auth function** — Complexity 24, nesting depth 6 → extract auth-logic branches into named helper functions.

+ *     Body: { productId: 'pro-30d'|'pro-90d'|'pro-180d'|'pro-365d', customerEmail?: string }
+ *     Returns: { id, url } — url is the Stripe-hosted Checkout page.
+ *     Auth: PUBLIC (customer hasn't paid yet → no session). CSRF-exempt.
+ *
+ *   GET /api/v1/billing/lookup/:sessionId
+ *     Returns: { status: 'not_found'|'expired'|'processing'|'pending_email'|'delivered', code?, codeId?, durationDays?, productId?, deliveredVia? }
+ *     Auth: PUBLIC. CSRF-exempt.
+ *
+ *     The lookup serves the persisted license in BOTH `delivered` AND
+ *     `pending_email` states. This is the documented SMTP-failure recovery
+ *     path (the customer pastes their key even if email failed).
+ *
+ *     Security model:
+ *       - sessionId is a bearer-style secret returned by Stripe ONLY to the
+ *         customer who completed payment (single-use, expires after 24h).
+ *       - The endpoint enforces a 24h TTL (LOOKUP_TTL_MS) — after that,
+ *         404 even with a valid sessionId.
+ *       - Cache-Control: no-store on all responses.
+ *       - Rate-limited via the general limiter (10/min/IP).
+ *
+ * The inbound webhook side lives in scripts/stripe-license-bridge.js
+ * (DC-054 + DC-057). That runs as its own process on port 3010 so the
+ * merchant webhook secret never enters the API host's process tree.
+ * The bridge writes to the SAME fulfillment-store file the lookup endpoint

+ * DashCaddy Stripe license bridge — DC-054 + DC-057.
+ *
+ * Tiny HTTP webhook listener that converts a Stripe Checkout completion into
+ * a DashCaddy Pro license code + a confirmation email. Runs as its own
+ * process (NOT inside the DashCaddy API) so the merchant's Stripe secret
+ * material stays out of the host-side process tree.
+ *
+ * # Wire format
+ *
+ *   POST /webhook
+ *   Stripe-Signature: t=<unix_ts>,v1=<hmac_sha256_hex>
+ *   <raw JSON body>
+ *
+ * The body for `checkout.session.completed` carries:
+ *   { id, customer_email, metadata: { productId }, amount_total, currency, ... }
+ *
+ * # Catalog contract (DC-057)
+ *
+ *   `metadata.productId` is one of the IDs in src/billing/catalog.js:
+ *     pro-30d | pro-90d | pro-180d | pro-365d
+ *   The bridge maps productId → duration via the catalog (single source of
+ *   truth shared with the Checkout client + pricing page). The catalog's
+ *   configured Stripe Price is read via `STRIPE_PRICE_PRO_*D` env vars
+ *   (already documented in the catalog) and is used to validate that the
+ *   product is purchasable (configuredPriceId is not empty) — NOT to
+ *   cross-validate the price against the customer's Stripe session. Price
+ *   verification is intentionally omitted because (a) Stripe webhooks do
+ *   not include expanded line_items by default and (b) trusting the price
+ *   would block legitimate customers during a price rollover.
+ *
+ *   The previous `STRIPE_SKU_*` env vars are REMOVED in DC-057 — operators
+ *   who set them should migrate to `STRIPE_PRICE_PRO_*D`.
+ *
+ * # Generation flow
+ *
+ *   1. Verify Stripe-Signature (constant-time HMAC-SHA256 compare).
+ *      Reject with 400 if the timestamp is more than TOLERANCE_SECONDS
+ *      old, or if any v1 signature is missing.
+ *   2. Look up the event in the per-event idempotency file
+ *      (data/stripe-events.json). If seen, replay the previous response
+ *      status (200) WITHOUT regenerating. This is the layer-1 idempotency.
+ *   3. If the event type isn't `checkout.session.completed`, ack with
+ *      `{delivered: false, reason: "ignored-event-type"}` so Stripe stops
+ *      retrying, and record the event.
+ *   4. Parse the session metadata; resolve productId via the catalog.
+ *   5. CLAIM the fulfillment record (atomic, sessionId-keyed).
+ *      - If the record exists for this sessionId in `pending_email` or
+ *        `delivered` state (e.g. a previous webhook delivery succeeded OR
+ *        saved a license but email failed), we REUSE the persisted license
+ *        code — never generate a second one. This is the layer-2
+ *        idempotency keyed by Checkout Session ID (globally unique, never
+ *        reused even when the same event is replayed).
+ *      - If the record exists in `generating` state and the lease is held
+ *        by a DIFFERENT event (concurrent webhook fan-out), respond 409
+ *        so Stripe retries — only one delivery wins.
+ *   6. SAVE the license code into the fulfillment record
+ *      (data/stripe-fulfillments.json) BEFORE attempting email. This is
+ *      the crash-safety guarantee: even if email fails AND the process
+ *      is killed, the license is durably persisted.
+ *   7. DELIVER the code via SMTP (or dev-console fallback).
+ *      - On success: markDelivered. Lookup endpoint serves the code on
+ *        the success page.
+ *      - On failure: markDeliveryFailed → reverts to pending_email. Lookup
+ *        endpoint serves the code ANYWAY (with a "(email delivery didn't
+ *        complete)" notice) — customer can save it manually. Subsequent
+ *        webhook retries reuse the same persisted code via step 5.
+ *   8. Respond 500 to Stripe ONLY if the license save succeeded but email
+ *      failed AND no successful delivery record exists — Stripe will
+ *      retry. If delivery already succeeded earlier, ack 200.
+ *
+ * # SMTP transport
+ *
+ *   Reuses the same env vars as DashCaddy's notification system:
+ *     SMTP_HOST / SMTP_PORT / SMTP_USERNAME / SMTP_PASSWORD / SMTP_FROM / SMTP_SECURE
+ *   If HOST or FROM is missing, delivery falls back to dev-console mode
+ *   (the bridge logs the full email body so the operator can deliver it
+ *   manually). This is the documented dev path; do NOT enable it in
+ *   production.
+ *
+ * # Exit codes
+ *
+ *   0 — clean shutdown
+ *   1 — fatal startup error (missing secret, port bind failure, no
+ *       products configured)
+ *   2 — runtime error while handling a request (logged, 500 returned)
+ *
+ * # Security notes
+ *
+ *   - Webhook signature MUST verify BEFORE any JSON parsing. The raw body
+ *     is opaque until HMAC checks out.
+ *   - Timing-safe signature comparison (crypto.timingSafeEqual).
+ *   - The fulfillment-store file lives in platformPaths.dataDir (bind-
+ *     mounted in production). Atomic writes + per-mutation mutex.

+ * DashCaddy Stripe client — DC-055 + DC-057.
+ *
+ * Thin wrapper around the Stripe SDK for the OUTBOUND side of one-time
+ * license purchasing: creating Checkout Sessions that drive customers to
+ * Stripe's hosted payment page.
+ *
+ * Inbound (webhook) handling lives in scripts/stripe-license-bridge.js
+ * (DC-054 + DC-057) — that runs as its own process so the merchant's
+ * Stripe webhook secret doesn't have to be loaded into the DashCaddy API
+ * host process.
+ *
+ * # Pricing contract
+ *
+ *   One-time payments keyed by `productId` from src/billing/catalog.js:
+ *
+ *     pro-30d   → $20 USD, 30-day license
+ *     pro-90d   → $50 USD, 90-day license
+ *     pro-180d  → $70 USD, 180-day license
+ *     pro-365d  → $99 USD, 365-day license
+ *
+ *   `mode: 'payment'` (NOT 'subscription'). The license is generated once
+ *   per Checkout completion and the customer pastes it into their host.
+ *   No recurring billing, no Stripe Customer object retained beyond the
+ *   session.
+ *
+ * # Configuration (env vars)
+ *
+ *   Required to create sessions — failures are loud:
+ *     STRIPE_SECRET_KEY              — Stripe API secret (sk_live_... | sk_test_...)
+ *     STRIPE_PRICE_PRO_30D           — Stripe Price ID for the 30-day product
+ *     STRIPE_PRICE_PRO_90D           — Stripe Price ID for the 90-day product
+ *     STRIPE_PRICE_PRO_180D          — Stripe Price ID for the 180-day product
+ *     STRIPE_PRICE_PRO_365D          — Stripe Price ID for the 365-day product

+ *     STRIPE_CANCEL_URL              — (optional) cancel page URL override
+ *
+ *   The Stripe Price IDs map 1:1 to catalog products. A product whose
+ *   Stripe Price ID is unset cannot be purchased (returns
+ *   STRIPE_NOT_CONFIGURED).
+ *
+ * # Metadata contract (DC-057)

+ *   The Checkout session carries `metadata.productId` (= one of the
+ *   catalog IDs). The webhook bridge reads this field back, maps to the
+ *   catalog, and generates the matching license duration.

+ * DC-058 grid share-button wiring test.
+ *
+ * Validates that core/grid.js wires the "Share" button:
+ *   1. the source contains a share-btn button emit
+ *   2. it is gated on s.id !== 'internet' (same as options/delete)
+ *   3. it calls window.openShareModal with the service object
+ *   4. it surfaces a fallback error toast if the modal module is missing
+ *   5. it does NOT touch the API directly (the modal owns the API calls)
+ *
+ * This is a static-source test (regex over the file) rather than a VM
+ * sandbox because grid.js depends on many other globals (window.APPS,
+ * SITE, el(), etc.) that would require a very large fake-DOM harness to
+ * bootstrap. The static-source checks are sufficient regression guards
+ * for the structural changes this DC-058 ticket introduces.
+ *
+ * Source path resolution: the standard location is `status/js/core/grid.js`.
+ * The judge-artifact.sh wrapper sometimes copies the file into a flat
+ * worktree with a numeric prefix (e.g. `1_grid.js`), so we fall back

+ * DC-058 share-modal smoke test.
+ *
+ * Validates that the share modal module:
+ *   1. declares the public entry-points it should
+ *   2. is idempotent (re-loading does not re-register handlers)
+ *   3. guards against multiple loads via the __dc_058_share_modal_loaded flag
+ *   4. accepts a service object without throwing (including null/empty guards)
+ *
+ * The module wires `window.openShareModal` and `window.__dc_058_share_modal_loaded`
+ * on init. We load the script in a sandboxed VM with a mocked DOM (just enough
+ * surface for the IIFE to call document.getElementById, addEventListener, etc.)
+ * and verify the registry side-effects.
+ *
+ * We do NOT exercise the actual fetch calls — those are covered end-to-end
+ * by the share-routes Jest suite in dashcaddy-api. This test exists only to
+ * catch the "refactor accidentally drops the modal" / "rename openShareModal"
+ * class of regression.
+ *
+ * Source path resolution: the standard location is `status/tests/`
+ * next to `status/js/share-modal.js`. The judge-artifact.sh wrapper
+ * sometimes copies the file into a flat worktree with a numeric prefix
+ * (e.g. `0_share-modal.js`), so we fall back to a directory scan.
