Four releases to porchsite.dev in one afternoon: a security fix for recovery links, a plain free-limit message, and the cost counseling every assistant must give before setup.

Four Porchsite releases went to porchsite.dev today. Two changed code. Two changed only docs.

## Releases

- **9381930 (security), 2:06 PM CT.** ` /recover `, ` /recover/options ` and ` /recover/verify ` now refuse a ` ?code= ` in the URL, because query strings end up in logs and referrers. Links that carry ` #code= ` still work, since the fragment never leaves the browser. Only the lowercase ` code ` key is refused.
- **8a38af0, 2:28 PM CT.** A short cost note is appended to the writer tools’ descriptions, so assistants see it. When D1 hits its free daily limit, the site now gives a plain message, and visitors get a 503. Assistants have to reconnect to pick up the new descriptions. A Workers request-limit overage still shows Cloudflare’s own 1027 page.
- **ba00f55, 2:54 PM CT, and a55686c, 3:15 PM CT.** Docs only. Cost counseling is now in ` llms.txt `, ` assistants.md ` and ` install.md `, and links to a new page, porchsite.dev/pages/costs/.

## The cost page

Every Porchsite site we run is on Cloudflare’s free plan. The page states the limits: Workers at 100k requests a day and 10 ms of CPU per request, and D1 at 5M rows read and 100k rows written a day. Going over stops the site until midnight UTC, and nothing is billed. A paid plan removes the limits but has no spending cap. Self-hosting costs about $5 a month, flat.

An assistant must now say all of this to a new owner before any setup step, then wait for a “go on”. “Go on” means continue on the free plan. It never means upgrade. The install, how-it-works and for-assistants pages carry caution lines, and the home page has a card: “Free, with daily limits”.

The Grok Bot Porchsite builder template skills were re-pinned to a55686c, with the cost talk mandatory.

## Issues

**A counter trigger would report false conflicts.** On hosted D1, ` meta.changes ` counts rows written by triggers. A counter trigger would make a normal one-row update report 2 changes. Porchsite reads that as “someone else edited this” and would fail a successful save, and it would break rollback. We confirmed this with throwaway D1 probes, then deleted them. PERF-9a is being redesigned so ordinary saves never fire the counter trigger.

**Rows read per request went up.** D1 rows read per plain request rose from about 456 to about 504, because the cost page is now live content. Against the 5M-row daily free limit, every row per request counts, so we track it.

## Backlog

AF-8: ` robots.txt ` will always spell out separate rules for search crawlers, user-triggered agents and training crawlers. The owner switch for blocking AI training, ` ai_training_disabled `, already exists and is off on porchsite.dev. AF-8 will make it easy to find.
