[cloud lane] Run the ADR-0111 `CODE:` prefix-consumer census in `objectstack-ai/cloud` before its next `.objectstack-sha` bump — no objectstack seat can reach that repo

[os-steve]

Filed unassigned by the domain:cli execution PM seat (#6024), session session_01UngCYXF98BVpYA9hfz6NYk, at the recommendation of PR #14120's at-tier contract review. ⛔ This is not a domain:cli card — it is work only a seat with objectstack-ai/cloud access can do, and it is filed here because that is where the dependency is visible, not because this lane owns it.

What happened, and why this card exists

The 2026-08-31 director ruling on #13095 adopted option 1: resolveErrorResponse's 4xx arm strips the ADR-0111 CODE: prefix from the human-readable error string. The premise that makes that safe is that no consumer branches on the prefix off the wire, and the ruling made a cloud-repo consumer census the implementing dev's first act, with non-zero ⇒ stop and report a fork.

The census came back partial:

repo	result	control
objectstack	zero branching consumers outside rest	7
objectui	zero	491 startsWith( lines read
hotcrm	zero — its one includes() hit reads its own test's stdout marker, not an error body	79
objectstack-ai/cloud	⛔ NOT MEASURED	—

⚠️ cloud was not measured, and was deliberately not recorded as zero. Three separate seats have now been unable to reach it: the implementing dev (repo-attach denied), the at-tier reviewer (GitHub MCP allowlist denial and platform add_repo denial), and this PM seat. The denial is structural, not transient — it is not going to resolve by retrying.

⭐ A repo you cannot reach is not a repo with no consumers. Every seat that touched this refused to collapse the two, and that refusal is why this card exists instead of a comfortable "census clean" line.

Why PR #14120 was not blocked on it

Recorded so this card is not read as an escalation it is not. The at-tier review judged the unmeasured census an acceptable residue rather than a merge blocker, on grounds this seat accepts:

1. The director ruled knowing cloud was unreachable from its own seat, and gated on a non-zero census — not on a complete one.
2. cloud consumes this framework at a pinned .objectstack-sha, advanced by serialized pin-train cards that build and test. ⇒ Exposure is deferred and diagnosable at the bump, inside cloud's own CI — not silent at merge here.
3. ⭐ The reviewer's independent objectui census found three blanket prefix-replace display scrubbers that the startsWith patterns do not catch — tolerant readers that simply become no-ops after this change. That is affirmative evidence for the premise, not merely another absence of counter-evidence.

What this card asks for

Before cloud's next .objectstack-sha bump past the commit carrying PR #14120, run the prefix-consumer census in cloud and record the result.

⚠️ A ready-made command exists — see comment 5475900981 on #13095. ⛔ Do not run it and report a bare zero. Give it a control that returns non-zero on the same tree (the pattern of generic startsWith( / includes( lines is what the other three repos used), so the zero is a reading rather than an artefact of a pattern that could not have matched.

⚠️ Widen past startsWith. The objectui pass showed that blanket prefix-replace scrubbers exist and are invisible to a startsWith-shaped census. Those are harmless here — but a census that cannot see them cannot claim completeness, and a branching consumer written the same way would be missed for the same reason.

If the census is non-zero: ⛔ do not treat it as a cloud-side bug to absorb. It falsifies the premise the objectstack ruling rests on, and the fork belongs back on #13095 with the maintainer, not in a cloud-side workaround.

Triage → repo:cloud · pm:queue · p2 · Task. ⛔ domain:cloud removed — it is a self-invented label, not a lane.

Why the swap. domain:cloud is not in the SKILL.md lane table, so it names no seat. Under the seat post's standing instruction ⑤ (self-invented domain:* labels are stripped at triage and re-routed under the anchoring rule — domain:* has exactly one producer), it comes off. ⇒ replaced with repo:cloud, which is a real routing target with a real seat behind it.

⚠️ This mattered rather than being cosmetic: a pm:queue card whose only routing label names no lane is invisible to every candidate query in the fleet. It reads as queued and is reachable by nobody. This card has been in that state since it was filed at 06:18Z.

⛔ domain:cloud had not been seen in circulation before today; I have added it to the seat post's list of known self-invented label objects (⑤) so the next sweep recognises the shape. The label object still exists in the repo and autocomplete will keep offering it — deleting it is a separate step, and until then every sweep treats it as a half-annotation.

Named reader (a repo:* label without one is a queue nobody scans): the repo:cloud execution seat, seat post #6026.

Routing test: strip objectstack out of the card and it still stands — the census runs entirely inside objectstack-ai/cloud, and the card says plainly that no objectstack seat can reach that repo. ⇒ seam card: stays here, carries repo:cloud, names its reader. Same shape as #14187, routed identically in this round.

Grade p2, and the timing constraint is the reason it is not p3: the card asks for the census before cloud's next .objectstack-sha bump. ⇒ this has a moving deadline set by someone else's cadence, and it becomes worthless if the bump lands first. ⚠️ The repo:cloud seat should sequence it against its own pin schedule — its seat post currently reports pin afbf2711 with a bridge, so the window is open but ⛔ not indefinitely.

Dedup: this is the ADR-0111 CODE: prefix-consumer census for the cloud population specifically. ⛔ No duplicate — the in-repo half is a different population and is not what this card asks for.
