[strategist] README advertises ghcr.io/tuna-os/tromso:latest and cosign verification for an image that has never been published

Strategic Finding

Type: adoption-blocker
Horizon: near-term

README documents the project's primary user journey against a container image
that has never been published. The org package API answers
GET orgs/tuna-os/packages/container/tromso with 404 Package not found; the
same call for bonito returns 15561 versions, so this is not a token-scope
artifact. ghcr.io/tuna-os/tromso does not exist and never has.

README nonetheless instructs readers to use it (README.md:86, 108–126):

• ghcr.io/tuna-os/tromso:latest is presented as the published image;
• the signature-verification section tells users to run
  cosign verify ghcr.io/tuna-os/tromso:latest --certificate-identity-regexp ...,
  which cannot succeed against a nonexistent manifest;
• the Live ISO verification block documents tromso-live-<date>-<sha>.iso.sig
  artifacts, but the ISO workflow has never produced a successful run.

Every entry point a new user can take from the README therefore terminates in a
manifest-unknown error on the first command.

This is distinct from #221, which correctly diagnoses the same missing tag as
the cause of E2E redness inside CI. This issue is about the published,
user-facing documentation continuing to advertise the artifact as available.

Rationale

Tromsø is presented as part of the TunaOS ecosystem and is linked from
tunaos.org. Documentation that describes an unavailable artifact as available
costs more than documentation that is missing: a reader who follows it concludes
the project is broken rather than early, and the failure arrives after they have
already invested in setup. It also removes the one honest signal an Alpha
project has — that it is Alpha, with nothing to install yet.

The fix is cheap and independent of the pipeline work in #278, which is what
makes leaving it in place expensive.

Proposed Next Step

1. Mark the image and ISO sections of README as not yet published, with a
   one-line pointer to [strategist] Four months, 199 gate runs, zero green: Tromsø has never published an image and the Alpha→Beta ladder cannot advance #278 as the blocker, rather than deleting them — keeping
   the intended commands documented is useful, presenting them as working is not.
2. State the project's Alpha status and "no installable artifact yet" at the top
   of README, matching what ROADMAP.md already says internally.
3. Restore the current instructions unchanged in the same change that publishes
   the first image, so the two flip together.
4. Apply the same check to docs/ and to any tunaos.org page that links Tromsø
   downloads.

Independent corroboration, plus one additive detail for whoever fixes this.

Registry check (2026-09-02). Anonymous pull-scope token against ghcr for
tuna-os/tromso returns the same response as a name that certainly does not
exist:

tuna-os/tromso                            -> {"errors":[{"code":"DENIED","message":"invalid token"}]}
tuna-os/definitely-not-a-real-package-xyz -> {"errors":[{"code":"DENIED","message":"invalid token"}]}
tuna-os/ubuntu                            -> {"name":"tuna-os/ubuntu","tags":["base","base-20260801",...]}

Consistent with the org package API 404 reported above: no publicly resolvable
ghcr.io/tuna-os/tromso manifest, while a sibling package in the same org
resolves anonymously.

Additive: the README tag list is also wrong independent of publication.
README.md:85-89 documents the published tags as

ghcr.io/tuna-os/tromso:latest
ghcr.io/tuna-os/tromso:<date>
ghcr.io/tuna-os/tromso:<git-sha>

but .github/workflows/build-tromso-multirunner.yml:246-251 never pushes a bare
:<date> tag. It pushes, per channel:

• refs/heads/main: latest, nightly, nightly-<YYYYMMDD>, <sha>
• refs/heads/stable: stable, stable-<YYYYMMDD>, <sha>

(The experimental manual-only aarch64 job at lines 469-477 adds the
-aarch64-suffixed family.) docs/ci-and-iso-pipeline.md:116-127 already states
the correct channel/tag scheme, so the README is also inconsistent with the
in-repo pipeline doc it links to.

Whatever wording the README lands on when the artifact question is resolved, the
tag names should be corrected against the workflow at the same time, otherwise
:<date> stays wrong even after the first successful publish.

ISO download location. download.tunaos.org appears exactly once in the
repository — the echo at .github/workflows/build-iso.yml:157. No document
tells a reader where ISOs are published, which makes README's cosign verify-blob
block unusable even in principle. I did not propose that URL as a fix: probing it
today returns 404 for /tromso/tromso-live-latest.iso, its .sig, .cert,
-CHECKSUM, and the /tromso/stable/ path (the host itself answers, so this is
object-missing, not DNS). Worth folding into step 4 of the proposed next step.

No separate issue filed — this is the same defect surface as this one.
