This val automates IndexNow submission by:

1. Crawling sitemap URLs.
2. Tracking submission history in project-scoped SQLite.
3. Submitting only changed URLs.

0. Read the IndexNow docs (indexnow.org/documentation) and make sure your key file is already hosted on your domain at a public URL like https://www.example.org/<key>.txt.
1. Add at least one site file in config/sites/*.json (see below for details).
2. Set required env vars (see below for details).
3. Open / to confirm the dashboard loads.
4. Run a safe dry run first: POST /run?dryRun=1 with x-indexnow-token.
5. After dry run looks correct, enable cron via indexnow.cron.ts for ongoing automation.

• indexnow.http.ts: primary HTTP entrypoint.
• indexnow.cron.ts: scheduled trigger that POSTs to the HTTP handler at /run.

• INDEXNOW_RUN_TOKEN (required): auth token required for /run (manual and cron).
• INDEXNOW_FORCE_TOKEN (optional but recommended): separate auth token required when using force=1.
• INDEXNOW_ENDPOINT (optional): defaults to https://api.indexnow.org/indexnow.
• INDEXNOW_PER_SITE_RUN_URL_LIMIT (optional): defaults to 5000; per-site queue cap per run before batching into IndexNow POSTs.
• INDEXNOW_ALERTS_ENABLED (optional): defaults to enabled; set to 0/false to disable alert emails.
• INDEXNOW_PUBLIC_BASE_URL (optional but recommended): absolute public val URL used for alert-email deep links (for example https://<your-val>.web.val.run).
• INDEXNOW_ALERT_TO_<SITE> (optional): per-site alert recipient email (e.g. INDEXNOW_ALERT_TO_HANAYOU).

Site configs live in config/sites/*.json with one site per file. At least one file must exist or the val will throw on startup.

Example: config/sites/hanayou.studio.json

{
  "host": "www.hanayou.studio",
  "sitemapUrl": "https://www.hanayou.studio/sitemap.xml",
  "keyLocation": "https://www.hanayou.studio/2dc12b205bfe46d19a75077e3991f7ce.txt",
  "alertToEnvVar": "INDEXNOW_ALERT_TO_HANAYOU",
  "includePrefixes": ["/journal/", "/guides/"],
  "excludePrefixes": ["/tag/", "/author/"]
}

Notes:

• Keep raw email addresses out of config/sites/*.json; set as an env var instead.
• If alertToEnvVar is omitted (or env var is empty), the val sends alerts to the default owner email.

Base URL pattern: https://<your-val>.web.val.run

Auth model:

• POST /run requires INDEXNOW_RUN_TOKEN.
• POST /run?force=1 also requires INDEXNOW_FORCE_TOKEN.
• POST /backfill requires INDEXNOW_RUN_TOKEN.
• GET / and GET /monitor are read-only and public.

Purpose: Render the React operator dashboard app shell.

Auth: none.

Query parameters:

Name	Required	Type	Description
site	no	string	Filter the dashboard to a single domain
runs	no	50 or 500	Run-history depth shown in tables.
issues	no	1/true/yes	Issue-focused mode (forces run history depth to 500).
run	no	integer	Pre-expand one run row in the UI.
diffUrl	no	full URL	With run, open the Raw HTML Diff panel for one URL.

Response:

• 200 text/html
• Runtime/config errors bubble as server errors.

Notes:

• / is the only dashboard UI route.
• Dashboard interactions fetch data from GET /monitor and update URL query params without full page reloads.

Example:

https://<your-val>.web.val.run/?site=www.hanayou.studio&runs=50

Purpose: Execute sitemap discovery + IndexNow submission workflow.

Auth headers:

Header	Required	Description
Authorization: Bearer <INDEXNOW_RUN_TOKEN>	yes (or x-indexnow-token)	Primary run token.
x-indexnow-token: <INDEXNOW_RUN_TOKEN>	yes (or Bearer)	Alternate primary run token header.
x-indexnow-force-token: <INDEXNOW_FORCE_TOKEN>	conditional	Required only when force=1.
x-indexnow-reason: cron_entrypoint	reserved	Used by indexnow.cron.ts for cron provenance.

Query parameters:

Name	Required	Type	Description
dryRun	no	1 or omitted	Simulate run with no submission side effects.
force	no	1 or omitted	Intentionally resubmit currently eligible unchanged URLs.
site	no	string	Restrict run to one configured host.

Status codes:

Code	Meaning
200	Run completed and hasErrors=false.
500	Run completed but hasErrors=true for at least one site.
401	Missing/invalid run token.
403	force=1 without valid/configured force token.
405	Method not allowed (POST required).
503	Server misconfigured (INDEXNOW_RUN_TOKEN missing).

Pragmatic response fields:

• Top-level: reason (manual_run_endpoint or cron_entrypoint), dryRun, force, runUrlLimit, hasErrors, startedAt, finishedAt.
• Per site (siteRuns[]): runId, host, filteredCount, changedCount, queuedCount, submittedCount, pendingCount, deferredCount, errors.
• Per site URL arrays: filteredUrls, changedUrls, queuedUrls.

Examples:

Dry run:

curl -X POST "https://<your-val>.web.val.run/run?dryRun=1&site=www.hanayou.studio" \
  -H "x-indexnow-token: <INDEXNOW_RUN_TOKEN>"

Real run:

curl -X POST "https://<your-val>.web.val.run/run?site=www.hanayou.studio" \
  -H "x-indexnow-token: <INDEXNOW_RUN_TOKEN>"

Force run:

curl -X POST "https://<your-val>.web.val.run/run?force=1&site=www.hanayou.studio" \
  -H "x-indexnow-token: <INDEXNOW_RUN_TOKEN>" \
  -H "x-indexnow-force-token: <INDEXNOW_FORCE_TOKEN>"

Purpose: Backfill one baseline raw-HTML snapshot per previously submitted URL that does not already have snapshot content. It captures current live HTML only and does not reconstruct historical page HTML.

Auth headers:

Header	Required	Description
Authorization: Bearer <INDEXNOW_RUN_TOKEN>	yes (or x-indexnow-token)	Primary run token.
x-indexnow-token: <INDEXNOW_RUN_TOKEN>	yes (or Bearer)	Alternate primary run token header.

Query parameters:

Name	Required	Type	Description
dryRun	no	1, 0, or omitted	Defaults to 1 when omitted; preview candidate URLs without writing snapshots (dryRun is camelCase).
site	no	string	Restrict backfill to one configured host.
limit	no	integer	Max candidate URLs to process per site in one request.

Status codes:

Code	Meaning
200	Backfill completed and hasErrors=false.
500	Backfill completed with fetch/write issues (hasErrors=true).
400	Invalid dryRun or limit query values.
401	Missing/invalid run token.
405	Method not allowed (POST required).
503	Server misconfigured (INDEXNOW_RUN_TOKEN missing).

Pragmatic response fields:

• Top-level: dryRun, limitPerSite, siteBackfills[], hasErrors, startedAt, finishedAt.
• Per site (siteBackfills[]): candidatesInBatch, insertedCount, fetchErrorCount, remainingAfterBatch, sampledUrls, errors.
• Inserted snapshot rows use run_id = NULL and snapshot_source = "backfill" (one baseline per URL).

Examples:

Dry-run preview (safe default):

curl -X POST "https://<your-val>.web.val.run/backfill?site=www.hanayou.studio" \
  -H "x-indexnow-token: <INDEXNOW_RUN_TOKEN>"

Real backfill batch:

curl -X POST "https://<your-val>.web.val.run/backfill?dryRun=0&site=www.hanayou.studio&limit=50" \
  -H "x-indexnow-token: <INDEXNOW_RUN_TOKEN>"

Purpose: Return JSON health/status data for automation and debugging.

Auth: none.

Notes:

• /monitor is JSON-only and does not render the dashboard UI.

Query parameters:

Name	Required	Type	Description
site	no	string	Limit output to one configured host.
runs	no	50 or 500	Number of recent run records per site.
issues	no	1/true/yes	Issue-focused mode (forces run history depth to 500).
run	no	integer	Include per-URL statuses for one selected run when available.
diffUrl	no	full URL	With run, include raw-HTML snapshot metadata + unified diff for that URL.

Status codes:

Code	Meaning
200	Monitor snapshot returned.
500	Runtime/config failure while building snapshot (error bubbles).

Pragmatic response fields:

• Top-level: generatedAt, runHistoryLimit, issuesOnly, selectedHost, selectedRunId, selectedDiffUrl, siteHosts.
• Aggregate status: totals (upToDateUrls, needsSubmissionUrls, retryPendingUrls).
• Run history: sites[].latestRun, sites[].recentRuns.
• Drill-down: sites[].selectedRunUrlStatuses (when run is provided and data exists).
• Diff drill-down: sites[].selectedRunDiff (when run + diffUrl are provided and snapshots exist).
• If a URL has only one snapshot, metadata is shown but no diff body is available yet.
• If the selected run has no run-linked snapshot for that URL, the UI may fall back to the latest available snapshot for inspection.

Example:

curl "https://<your-val>.web.val.run/monitor?site=www.hanayou.studio&runs=500&issues=1"

• submittedCount counts successful IndexNow HTTP 200 responses.
• pendingCount tracks IndexNow HTTP 202 responses.
• deferredCount means changed URLs were capped by INDEXNOW_PER_SITE_RUN_URL_LIMIT.

SQLite tables:

• indexnow_url_state_v1: per-URL state (seen/submitted timestamps, lastmod, status).
• indexnow_run_log_v1: per-run summaries for observability and debugging.
• indexnow_url_snapshot_v1: queued-URL raw HTML snapshots + metadata for diff inspection.

Snapshot retention policy (hard-coded):

• Keep snapshots for up to 14 days.
• Always keep at least 3 snapshots per URL (even if older than 14 days).

This val uses https://esm.town/v/std/sqlite/main.ts so data is scoped to this val project.

• INDEXNOW_PER_SITE_RUN_URL_LIMIT is applied per site for each run.
• If more changed URLs are discovered than the limit, the remainder is deferred to future runs.
• To intentionally resubmit unchanged URLs (still within limit), use force=1 with x-indexnow-force-token.

1. Daily/incident check:
   • Open / dashboard and confirm site health cards are green.
   • Review recent runs for pending, deferred, or Error statuses.
2. Manual safe run flow:
   • Run dry run first: POST /run?dryRun=1.
   • Review changedCount and queuedCount.
   • If expected, run real submission: POST /run.
3. If deferred URLs accumulate:
   • Confirm this is expected (large content release, migration, etc.).
   • Tune INDEXNOW_PER_SITE_RUN_URL_LIMIT and/or schedule frequency.
   • Use force=1 only when you intentionally want to resubmit unchanged URLs.
4. Alert triage:
   • Alert with pending: retry/watch next run; investigate endpoint throttling.
   • Alert with deferred: consider run URL-limit tuning or additional runs.
   • Alert with errors: requires action before trusting indexing progress.
5. External verification:
   • Use Bing Webmaster Tools to verify ingestion trends.
