Every build writes the exact source it was built from, uncommitted work and
new files included, as source.tar.gz next to the app, named after that tree.
Docker builds, which have no git, pack the build context and name it by a
hash of its files. The sign-in page and Settings > About link to it instead of
a repository that can drift.
What users, operators and packagers see no longer names the upstream server:
- interface text, in all nine catalogues, with a token-session line for
Security;
- server messages;
- the settings, now MAIL_SERVER_URL, MAIL_SERVERS_FILE, ADMIN_URL and
MAIL_SERVER_FOLLOW_ADVERTISED_URLS, and mail-servers.example.json;
- the Tenants notice, which is gone;
- the README, CONTRIBUTING and SECURITY.
ihasmail's own FEATURES, KNOWN-ISSUES and ROADMAP stay with public ihasmail,
and INBUXA.md is folded into the README.
The deploy on 2026-09-08 went out at the origin and did not arrive.
Cloudflare went on handing out the previous `sw.js` -- `cf-cache-status:
HIT`, with an edge TTL of four hours, longer than the hour we asked for
-- because the file is neither a hashed asset nor HTML and so fell into
the ordinary `max-age=3600` case.
That is not a freshness preference. The service worker is the app's whole
update mechanism: a browser holding the old one goes on being served the
shell that worker knows and never learns a deploy happened, so the deploy
simply does not land. The manifest matters for a second reason -- the two
have to agree. A fresh manifest advertising a share target, answered by a
worker that has never heard of one, sends the share to the server for a
405. Either being old is survivable; disagreeing is not.
`no-cache` rather than `no-store`: both may still keep a copy, they just
have to revalidate it, which is a 304 and costs nothing. Neither gets to
answer with its own copy without asking.
Narrow on purpose -- two files, named, rather than a policy that quietly
stops the icons and fonts being cached as well.
