The 2026-08-07 regeneration rendered '?' for 5 of 21 recipes. '?' is meant to be a rare 'we tried and could not tell'; at that rate it is indistinguishable from noise and hides the real unknowns. Three causes, none of them genuine uncertainty: 1. URL EXTRACTION BUG (mine). The registry is markdown, so urls appear inside `backticks` and 'quotes'. The extractor captured the trailing punctuation, so it fetched https://docs.n8n.io/release-notes/` and https://git.autonomic.zone'` — both 404 on the malformed url, both 200 when clean. Trailing markdown punctuation is now stripped. Fixed immich + n8n. 2. STALE REGISTRY URL. mattermost-lts pointed at docs.mattermost.com/about/mattermost-changelog.html, which 404s; the page moved to /deploy/. Corrected (same class as the pgautoupgrade fix). 3. WRONG SEMANTICS FOR 'NO UPGRADE'. lasuite-docs and custom-html-tiny were up-to-date this run, so no scan block existed and the report fell back to '?'. But a recipe with no upgrade has nothing an upgrade could have fixed — that is 0, not unknown. The report skill now says so explicitly, restricts '?' to scans that RAN and reported genuinely failed sources, states that benign notes (no-advisories-published / template URL) never trigger '?', and instructs that many '?' is itself a bug to raise in the Addendum. Result across all 16 scanned recipes of that run: 0 failed sources (was 5). Counts also improved with the classifier fix: discourse 130->133, keycloak ->7.
Upstream release-notes registry
Per-recipe maps of where each image's release notes / changelog live. This is the cc-ci analog of
recipe-maintainer's recipe-info/<recipe>/upstream.md: the /recipe-upgrade skill reads
cc-ci-plan/upstream/<recipe>.md so it doesn't have to rediscover the upstream source for every image
on every weekly run — discover once, persist, reuse.
How /recipe-upgrade uses it (step 1)
- Read
cc-ci-plan/upstream/<recipe>.md. - If it's missing, or an image in the recipe's
compose.ymlisn't covered (new/renamed service), discover the upstream project + releases page for each uncovered image (WebSearch the image → its GitHub/source repo → its releases/changelog page), then write/update this file and commit it (git -C /srv/cc-ci-orch add cc-ci-plan/upstream/<recipe>.md && commit && push). - Fetch the release notes from these URLs between the current → target version of each service.
Format (one file per recipe)
# Upstream sources — <recipe>

|---------|-------|-------------|----------------------|
| app | cryptpad/cryptpad | https://github.com/cryptpad/cryptpad | https://github.com/cryptpad/cryptpad/releases |

## Standing notes
- <recipe-specific upgrade gotchas worth remembering between runs, e.g. "n8n: postgres volume path
changed from /var/lib/postgresql/data to /var/lib/postgresql in 2.2x">
Keep URLs canonical (the project's own releases/CHANGES page, not a mirror). Add a Standing notes section for migration gotchas you only want to learn once.
