Serve a content repo's .well-known/ at the site root

Everything a site has to publish for another program to find it lives
under /.well-known/, and portal had no way to put a file there: the
catch-all answered those paths 200 with the app shell, so a client
probing for security.txt or matrix/server got HTML where it expected a
document, and could not tell a missing file from a present one.

The prefix is the one place this is safe to overlay. RFC 8615 reserves
it, and a question's id comes from a file name under questions/, which
cannot begin with a dot - so no file a repo ships can shadow a page. The
path still goes through is_safe_site_path, so it cannot climb out of the
repo either, and a miss is a real 404.

Types: an extensionless file under the prefix is JSON, which is what
matrix/server and nodeinfo are; .mobileconfig is the Apple profile type,
without which iOS downloads a profile instead of offering to install it.

+## 0.6.21 (2026-10-07)
+
+- A content repo's `.well-known/` is served at the site root (`/.well-known/security.txt`, `/.well-known/assetlinks.json`, `/.well-known/matrix/server`), and a miss there is a 404 instead of the app shell answering 200 with an HTML page. RFC 8615 reserves the prefix and a question's id cannot begin with a dot, so nothing a repo ships can shadow a page. An extensionless file under it is typed as JSON, by the convention those files follow; `.txt`, `.xml`, `.webmanifest` and `.mobileconfig` are typed too, the last so an Apple configuration profile offers to install rather than download.
+
+## 0.6.20 (2026-10-05)
+
+- A releases card lets a platform's file carry an architecture: a Mac visitor is offered the `macos-arm64` file, not sent to TestFlight past it.
+
+## 0.6.19 (2026-10-05)
+
+- A `kind: url` resource whose JSON is a releases manifest (`latest`, `versions` with per-platform `assets`, `channels` such as a package repo or TestFlight) renders as a download card: the file for the visitor's own platform first, decided in the browser, the rest and the channels folded. Written for redoal's public releases at dl.redoal.com (docs: content-reference, "A releases manifest").
+
+## 0.6.18 (2026-10-03)
+
+- `iris check --findings <out.jsonl>` writes every finding as JSON: a stable `id` (scope, need, code and subject, nothing of the wording), `level`, `code`, `scope`, `need`, `subject`, `message` and `fix`. Every message that knows its fix now says it after "fix:". The codes are listed in docs/lint.md.
+- `portal generate` follows its findings through: each structure round is logged as fixed, still open, new and reopened; a fix round is shown the open findings with their fixes and only the files they name; a change that reopens a closed finding is undone; and the phase stops when a round closes nothing, writing what is left to run.log. A hesitant visitor no longer triggers a wording rewrite by itself, only a misroute does. A lint without `--findings` is still driven the old way.
+
 ## 0.6.17 (2026-10-02)
 
 - A desk shows every record still moving and only the three most recently finished (a final state: no move out of it), with "Show older" for three more at a time. A desk that has run for a year is still about the work in hand.
