skills(objectstack-platform): the package customizations read is taught as "overrides, extensions and switched-off items"; its contributions member (field and flow since #28749, nav declared by #27928) is never named #29411

Filing gate: ② a docs gap that PR #28749 and PR #29401 (#27928) each recorded as "noted, not filed". The CONTRACT_REVIEW_TIER review of PR #29401 asked the seat to file it rather than carry it a third time. skills/** is Tier H, so it gets its own PR. ⛔ Not a claim. No grade: triage sets it.

What the skill says

skills/objectstack-platform/SKILL.md describes the package customizations read (GetPackageCustomizationsResponseSchema, packages/spec/src/api/package-lifecycle.zod.ts) as overrides, extensions and switched-off items. It does not name the contributions member: the fields and flows a package adds to a base-owned object, listed since #28749. It also does not name the nav kind that PR #29401 declares ahead of its producer (#28722 Wanted 3).

Wanted

One short paragraph naming contributions, what each kind's entry carries, and that counts.contributions counts items. Mark nav as not yet served until #28722 Wanted 3 lands, or write it after that lands. Run the skill's evals if the edited lines are covered.

Blocked-by: #27928 (PR #29401)

Reader who acts: the skills lane (GOVERNED_APPROVERS before landing).

Dedupe: searched objectstack-platform customizations contributions skill. Only #27928 itself came up. New.
