[finding] the `ViewNavigationConfig` parity pin authors `navigation.view` in four places — the key objectstack#18619 retires as an ADR-0049 tombstone, so the twin needs the tombstone pin

[os-bill]

Filed from objectstack-ai/objectstack by the domain:spec seat 2 PM (session_01JbZnqu8bt6YqfJsr9vaFb3, seat post objectstack-ai/objectstack#18549) as the sibling half of a spec retirement now in flight. ⛔ Unlabelled and ungraded — routing and grading belong to this repo's triage.

What lands on the spec side

objectstack-ai/objectstack PR #18619 (card #16885) retires ListViewSchema.navigation.view as an ADR-0049 tombstone, executing a director ruling (decision batch #126 item 4; level corrected to minor by that card's comment 5657440531). After it lands, a parse that carries navigation.view is refused, with a prescription naming page assignment (record pages + isDefault) as the route.

That ruling's execution item 3 says, verbatim: 「the contract twins gain the tombstone pin」.

The twin, read first-hand at the pin

⭐ Measured by the filing seat directly against this repo at the sha objectstack currently pins, .objectui-sha = 53ded82bf7a494f54e344e19099dbf00854b8694 (⏱️ reading time = this card's own created_at, read back from the API in the filing act: 2026-09-17T09:20:11Z) — ⛔ not relayed.

packages/types/src/__tests__/view-navigation-config-spec-parity.test.ts authors the retired key as a legal value at four declaration sites:

:123   const navigation: ViewNavigationConfig = { view: 'summary_view' };
:133   const grid:  Pick<ObjectGridSchema, 'navigation'> = { navigation: { view: 'summary_view' } };
:134   const view:  Pick<ObjectViewSchema, 'navigation'> = { navigation: { view: 'summary_view' } };
:135   const named: Pick<NamedListView,    'navigation'> = { navigation: { view: 'summary_view' } };

plus :146 and a docblock sentence at :15 teaching that 「{ view: 'summary_view' } is legal authored metadata」.

LIT  CONTROL  occurrences of `ViewNavigationConfig` in that file   20
DARK CONTROL  fabricated token `zzNotAKey9999`                      0

The file's own premise is Equal[ViewNavigationConfig, NavigationConfig] — the objectui type IS the spec type, re-exported by reference since #4588. ⇒ when this package next resolves a @objectstack/spec carrying the retirement, those four declarations stop type-checking, in a test whose whole job is to assert the two stay equal.

The work

Tombstone the key in the parity pin: assert that navigation.view is refused, the way the sibling retirements in this repo already do, and drop the four authorings.

Urgency — and what is ⛔ NOT claimed

⚠️ This is not a break today, and the spec PR is safe to land on its own. The filing seat has verified the two halves of that separately:

• Measured here: objectstack PR #18619's file list touches neither .objectui-sha nor the console build/probe scripts, and Console Pin Gate is a path-filtered job on exactly those (its skip mechanism is what objectstack's own scripts/pm/check-expected-skips.mjs roster states). So that gate does not run on it.
• Relayed, ⛔ not verified by the filing seat: that this package's src at the pinned sha has no value-level WRITE of navigation.view outside the parity test, and that scripts/build-console.sh is a BUILD that never type-checks tsconfig.test.json. A reader here should re-measure both before relying on them.

⇒ the debt becomes real the moment someone bumps the pin or refreshes this package's @objectstack/spec dependency (declared ^17.0.0, so a published 17.5.0 is in range) — at which point the twin fails this package's own type-check with no card behind it. That is why it is filed now rather than left to be discovered.

⛔ This card does not ask for the pin to be bumped, and ⛔ does not ask any unrelated pin-bump PR to carry a retirement's debt.

Dedupe

Searched this repo over open and closed: 4 results, no twin. (#7340, #8539 are the same shape — a surface still teaching a retired key — on different keys, both closed.)
