Merge Risk: ⚪ Minimal · up to The node and resolver now require the same configured URL, and production setup rejects local origins. No actionable merge-blocking risk remains beyond normal checks. 🚥 Pre-merge checks | ✅ 7✅ Passed checks (7 passed)

- Around line 205-207: Update the production resolver validation around the
localhost resolver constant to parse and compare the URL host, so trailing-slash
variants such as http://localhost:8003/ are rejected after normalization. Add a
unit test covering the trailing-slash case and preserve acceptance of valid
non-localhost resolver URLs.
In `@crates/dpp-common/src/config.rs`:
- Line 88: Update parse_resolver_base_url to remove the raw URL value from every
rejection message, including the absolute-URL context, scheme, host, and
query/fragment errors. Add a test confirming credentials in a rejected URL never
appear in the returned error.
In `@crates/dpp-node/src/config.rs`:
- Line 550: Add one explicit SAFETY comment documenting why the environment
mutations are safe, covering set_required_env, clear_env, and the affected
#[serial] tests; keep the tests in the current process.
In `@docs/guides/DEMO-RUNBOOK.md`:
- Around line 46-48: Update the sentence describing how many of the three
settings fail silently in the demo runbook: state that only one fails silently,
or remove the sentence. Keep the surrounding explanation of RESOLVER_BASE_URL
and CREDENTIAL_ISSUERS_SELF unchanged.

- Line 227: Update preflight_prod_env to resolve RESOLVER_BASE_URL from the
shell environment first, falling back to the parsed .env value only when unset,
then apply loopback_host to the selected value. Add a committed test covering a
shell localhost override when .env contains a public URL.
- Around line 255-256: Update the IPv6 branch in the loopback host check to also
reject IPv4-mapped addresses whose embedded IPv4 address is loopback; retain the
existing native IPv6 loopback check. Add the mapped-loopback URL to the rejected
values in the existing test.

Closes #382 with option A, locked by the maintainer: no default in either binary, the value is required,
.env.examplecarries a visiblehttp://localhost:8003, and compose hands the one value to both services with${RESOLVER_BASE_URL:?}.What running it showed
#382 was about the node's default. Running the 0.14.0 release-candidate images end to end, configured exactly as
DEMO-RUNBOOK.mdsays, found the same default a second time, in the resolver, and worse wired:http://localhost:8003/01/09590000000045/10/VBX-EV-2026-0421/21/…into the carrier — correct;307 → https://id.odal-node.io/dpp/…, a host that does not resolve; the AAS response's canonicalLinknamed it too.docker-compose.ymlgives the resolver an explicitenvironment:block and noenv_file, anddpp-resolver/src/main.rsdefaulted to the dead host, so the operator's value never reached the resolver. Every scanned QR code went nowhere while the node's own configuration looked right. The same image with the variable passed redirects tohttp://localhost:8003/dpp/…— verified live before writing this.Present since at least v0.13.0. It ships inside the release because the compose file is
include_str!'d into theodalCLI, and a tag moveslatest.The change
https://id.odal-node.ioConfig::from_envunwrap_or_elsesdpp_common::config::resolver_base_urlenv_file; resolver never${RESOLVER_BASE_URL:?}—odal uprefuses before anything starts.env.examplehttp://localhost:8003, marked requiredlocalhost,*.localhost, loopback IPv4/IPv6, however spelledThe reader refuses anything that is not an absolute
http/httpsURL with a host, and anything carrying credentials, a query or a fragment — each would be concatenated into every carrier. It returns the value without a trailing/; the GTIN redirect used it as-is while the other two paths trimmed it. A refusal echoes the value only with its credentials, query and fragment removed.Review round 1 (
40c7ff4) took all four CodeRabbit findings: the preflight compared a literal, sohttp://localhost:8003/passed and the node then trimmed it into the refused value — it now parses the host; refusals echoed the raw value, credentials included; a SAFETY note covers the tests' env mutation; and the runbook no longer says two of three settings fail silently. Both new tests were mutation-checked — each goes red with its fix removed.Review round 2 (
0b2bcf6) took both findings on40c7ff4:.envonly, and compose does not. A variable exported in the invoking shell overrides.envfor interpolation, andodal uphands compose its own environment — so a staleRESOLVER_BASE_URL=http://localhost:8003export passed a file holding a real origin, and was what got signed. The same held for every key the preflight checks (a shellADMIN_PASSWORD=adminpassed too). The checks now live inprod_env_problems(file, shell), judged on the value compose will use, and a refusal says when the value came from the shell.shellis a parameter, so the tests never mutate the process environment — which is not hermetic anyway, sincejustloads the developer's own.envinto every recipe.[::ffff:127.0.0.1]passed, becauseIpv6Addr::is_loopbackis::1only; mapped addresses are now unwrapped, and unspecified addresses (0.0.0.0,::) are refused as naming this machine too.a_shell_export_is_judged_over_the_env_fileis mutation-checked: with the shell ignored it goes red.just checkgreen, 1325/1325.localhost:8003without a scheme parses as a URL whose scheme islocalhost, so the scheme check is what catches the most likely typo — pinned by a test.Also:
scripts/install.shwrites the value;OPERATOR-SETUP.md,DEMO-RUNBOOK.md§1,CLAUDE.mdand two OpenAPI descriptions stop claiming a default (bundle regenerated — two lines each).Breaking
A deployment that never set
RESOLVER_BASE_URLno longer starts. That is the point: what it was starting with was broken, and a wrong value is signed into labels that cannot be recalled. Changelog entry is under 0.14.0### Breaking, since this lands before the tag.Not here
.envmust now set this value; a stack rendered without it will refuse to start, by design.scripts/install.shis stale in other ways — it sets noDATABASE_APP_PASS/DATABASE_POSTGRES_PASS, which compose already requires — so it fails before reaching this. Only the one line this change owes it is added.VAULT_BASE_URLin the resolver still defaults tohttp://vault:8001. Different failure (loud, not signed into anything), left alone.Verified
just checkgreen — 1324/1324 unit tests, including the new ones.http://localhost:8003/dpp/…and the AASLinknames it; without the variable,docker compose configrefuses withRESOLVER_BASE_URL must be set in .env.Summary by CodeRabbit
Breaking Changes
RESOLVER_BASE_URLis now required for both the node and resolver; services won’t start if it’s missing or blank. The previous built-in resolver URL is no longer used.Documentation
