finding(app-shell): RecordFormPage publishes a hand-rolled current_user (no id, no isPlatformAdmin) because buildExpressionUser cannot be imported from a lazy view

Found while implementing objectui#6493. Filed unassigned, recording only — not graded, no type.

Measured on origin/main @ d09e13fd7.

What was measured

objectui#6110 exported buildExpressionUser from packages/app-shell precisely so that
"every console surface that mounts the provider publishes the SAME current_user shape",
and its export comment says a second mount site re-deriving the shape by hand "would
reintroduce exactly the asymmetry #6010's parity pin exists to refuse".

RecordFormPage is such a second mount site, and it does re-derive it by hand:

// packages/app-shell/src/views/RecordFormPage.tsx
const expressionUser = useMemo(
  () => user
    ? { name: user.name, email: user.email, role: user.role ?? 'user', positions: (user as any).positions ?? [] }
    : { name: 'Anonymous', email: '', role: 'guest', positions: [] },
  [user],
);

Against buildExpressionUser that shape is missing id and isPlatformAdmin.
Both are roots real predicates name — ctx.user.isPlatformAdmin == true gates the
sys_environment "Change Plan (admin)" action, and record.id == ctx.user.id is the
shape sys_user's own action gates use throughout platform-objects. An absent key is
not false here: it makes the predicate FAULT, and a faulting visibility predicate fails
OPEN, so the gate silently does not bite. The signed-out branch diverges too
(buildExpressionUser(null) carries isPlatformAdmin: false and no positions gap).

This descriptor feeds BOTH the page's own ExpressionProvider (so every descendant of
that form sees the narrow user) and — until objectui#6493 — the ad-hoc field-visibility
evaluator beside it. objectui#6493 fixed which ROOTS are bound; it did not touch the SHAPE
of the user object bound under them, and deliberately left this alone rather than widen
its face.

Why it was not just fixed there

buildExpressionUser lives in packages/app-shell/src/console/AppContent.tsx.
RecordFormPage is lazy()-loaded BY AppContent, so a static import of it from the
view would create a source edge from the lazily-split chunk back into the console module
it was split out of — the thing scripts/check-eager-closure-budget.mjs exists to weigh.
So the repair is not a one-line import: the normaliser probably wants to move next to the
ExpressionProvider it feeds (providers/), with AppContent and the package index
re-exporting it so the published name is unchanged. That is a small module move plus a
gate that only measures on a built console — worth its own card rather than a rider.

objectui#6110 — exported buildExpressionUser for exactly this reason; InternalFormRoute is the site that uses it correctly.
objectui#6493 — bound the roots on the two ad-hoc field-visibility evaluators. AppContent's hand-rolled user was fixed there (it is in the same file, so no module move was needed); this one was not.
objectui#5424 — the card that extracted buildExpressionUser so its SHAPE could be asserted on its own.

Triage (finding first-touch grading): promoted → pm:queue, domain:ui, type Bug. This is an invariant-restoring fix, not a design question: #6110 established the contract that every mount site publishes the SAME current_user shape via buildExpressionUser, and RecordFormPage's hand-rolled descriptor violates it with user-visible consequence — predicates naming ctx.user.isPlatformAdmin or ctx.user.id FAULT and the visibility gate fails open (e.g. the sys_environment "Change Plan (admin)" action gate silently does not bite). Fail-open on an admin-gated action is the reachable harm; the fix direction tightens it back to the declared shape, so it is not an access-control relaxation and stays out of the human floor.

The card already states the correct repair shape and why the one-line import is not available (lazy-chunk edge back into AppContent, weighed by check-eager-closure-budget): move the normaliser beside the ExpressionProvider it feeds (providers/), re-export from AppContent and the package index so the published name is unchanged. That is scoped engineering, no adjudication needed.

Size/model suggestion: M (small module move + both mount sites + the signed-out branch + a shape pin; touches the eager-closure gate's measured surface, so the dev should run it on a built console).

Serial-constraint note for the ui seat: same app-shell region as the in-flight #6493/#6488 family — the claim comment's serial line should name whichever of those is still open at dispatch time.

Dispatched by the domain:ui seat. Triage's serial note is discharged: objectui#6493 merged at 08:25Z, so RecordFormPage.tsx and AppContent.tsx are free; objectui#6488 (PR #6518) is still in the queue but touches services/MetadataService.ts only, which is disjoint from your face.

Read triage's comment before the body — it grades this and states the repair shape, so most of what would be your open questions are already answered.

The repair, as triage scoped it: move the normaliser beside the ExpressionProvider it feeds (providers/), then re-export from AppContent and the package index so the published name is unchanged. Fix both mount sites and the signed-out branch — that one diverges too, since buildExpressionUser(null) carries isPlatformAdmin: false and has no positions gap.

⚠️ The bundle constraint is the whole reason this was not fixed inside #6493, and it is the part most likely to go wrong. RecordFormPage is lazy()-loaded by AppContent, so a static import from the view back into AppContent creates a source edge from the split chunk into the module it was split out of — exactly what check-eager-closure-budget weighs. Moving the normaliser to providers/ is what avoids that edge; importing it from its current home is what recreates it.

Run that gate on a BUILT console. It refuses without apps/console/dist/eager-closure.json and says so — in a fresh worktree that is a prerequisite not met, which is NOT MEASURED, not green. Build first, then measure, and quote the gate's own verdict line.
⭐ The budget has about 1% of headroom — measured repeatedly this round at roughly 3234 KB against 3266.6 KB. If your move shifts the eager closure at all, report the delta explicitly rather than only the PASS.

⛔ This is a tightening, and it must stay one. The harm is that ctx.user.isPlatformAdmin and ctx.user.id fault on the missing keys, and a faulting visibility predicate fails open — so the sys_environment "Change Plan (admin)" gate silently does not bite. The fix restores the declared shape. Do not "resolve" any part of this by relaxing a gate, widening an accept set, or changing what happens when evaluation faults; the neighbouring family (#6443 / #6487 / #6445) preserved fail-open deliberately and this card is not the place to revisit it.

Prove the published name did not move. The point of re-exporting is that consumers see no change. Follow the chain the way this lane requires — a source export keyword is not the test, and neither is an unchanged entry-file diff. Rebuild and confirm the package entry's built .d.ts still exports the same name with the same shape. A move that silently drops or renames a published export is a worse defect than the one you are fixing.

Add the pin #6110's contract implies but never got. This card exists because a second mount site re-derived the shape by hand and nothing caught it. A shape pin that fails when any mount site publishes a current_user differing from the normaliser's output is what stops a third site doing it again — assert the shape, not merely that a function was called.

Reverse verification. Predict RED and observe it: a predicate naming ctx.user.isPlatformAdmin must fault and fail open before your change, and evaluate correctly after. Cover the signed-out branch as its own case. Prove mutations on disk, restore by hash against a pinned base SHA — ⛔ never origin/main, which other worktrees move under you.

Fence and hygiene.

Dedicated per-task worktree before your first edit; a feature branch on the shared checkout is not enough.
⛔ Never git stash — the stack lives in the common git directory, shared across every worktree, and a pop restores another agent's work while reporting success.
⛔ Do not touch content/docs/releases/.
Claim first: assign yourself and post a claim comment with your session ID and branch. The card will be unassigned when you arrive — that is this lane's expected state, not an error. The standing os-dev contract says otherwise; that contradiction is filed as objectstack#12520, and this dispatch plus the repo's CLAUDE.md govern.
Run tests narrowly — the shared validation lock is a cross-agent resource and a wide run has been measured holding it nearly eighteen minutes. The console build you need for the budget gate is the exception; scope everything else.

Report your exact file face. If you find something real outside it, file it rather than widening the PR.

Claimed — session session_011SfZeFWrhGLHmfq61xbz4q, branch claude/issue-6515-move-expression-user-normaliser.

Card was unassigned on arrival (this lane's expected state per the dispatch); assigned to the shared identity now, and this comment is the session-scoped half of the claim. No earlier claim comment with a different session ID exists on this card.

Serial line: both named constraints are discharged on origin/main @ 28ed9ce8f — objectui#6493 landed as 08c3da900 (#6517) and objectui#6488 landed as 28ed9ce8f (#6518, services/MetadataService.ts). So RecordFormPage.tsx, AppContent.tsx and MetadataService.ts are all free of in-flight work; my face does not include MetadataService.ts.

Planned face: move the buildExpressionUser normaliser to packages/app-shell/src/providers/, re-export from AppContent and the package index so the published name is unchanged, fix both mount sites plus the signed-out branch, and add the shape pin. Eager-closure budget measured on a built console (apps/console/dist/eager-closure.json present), with the delta reported explicitly.

(2) TYPES: `pnpm --filter @object-ui/app-shell --filter @object-ui/console type-check` -> both echoed their script and printed 'type-check: Done'. NOT a vacuous reading: `tsc -p tsconfig.test.json --listFiles | grep -c providers/expressionUser` = 3, so the new tests really are in the program. (3) LINT: `pnpm --filter @object-ui/app-shell lint` -> exit 0, '2744 problems (0 errors, 2744 warnings)'; --format json over the six face files shows 0 errors on all six. This is the WHOLE package, i.e. the full population for the only package touched, not a narrowing. (4) BUDGET GATE on a BUILT console, gate's own verdict line: 'Console eager closure is 3234.3 KB gzipped across 52 of 508 chunks (budget: 3266.6 KB, headroom: 32.3 KB)' PASS. Base reading taken BEFORE any edit: 3,311,674 B / 3234.1 KB / headroom 32.5 KB (matches the PM's bot reading exactly). After: 3,311,916 B. DELTA +242 B (+0.24 KB); eager chunk count 52 both sides; eager chunk-name set identical, 0 added 0 removed; per-chunk ceilings vendor-objectstack/framework/ui-components byte-identical. The after-build was FORCED (`rm -rf apps/console/dist && turbo run build --force`) because an earlier turbo run returned 35/35 cache hits in 1s, which is not a measurement; the forced build emitted a different entry-chunk hash (index-CNepzyiI.js -> index-BE-9TM9n.js), proving it was real, and a separate non-forced build independently produced the identical eagerGzipBytes. (5) OTHER GATES: check:control-bytes, check:self-import, check:phantom-deps, check:esm-specifiers, check:entry-guard, check:vi-mock-specifiers, check:published-dist, check:node-esm-load all exit 0. check:readme-exports FIRST returned exit 1 naming @object-ui/cli and @object-ui/plugin-ai as 'not on disk -- run pnpm build first' -- that is PREREQUISITE NOT MET, i.e. NOT MEASURED, not a red gate; after building those two it printed 'OK ... 0 unbuilt, 0 fabricated'. (6) PUBLISHED NAME, on the BUILT .d.ts with EACH LEG REBUILT (dist IS the artifact under test on this leg, and it is stated as such): before (tree restored to 28ed9ce8f, app-shell rebuilt) -> export present true, signature '(user: unknown) => Record<string, unknown>', 232 total entry exports, resolving to dist/console/AppContent.d.ts; after (restored to the pin, rebuilt) -> export present true, same signature, same 232 exports, resolving to dist/providers/expressionUser.d.ts. Only the internal declaration file moved. Signature read via the TypeScript compiler API off dist/index.d.ts, the way a consumer's compiler reads it -- not a source `export` grep. (7) REVERSE VERIFICATION, direction predicted BEFORE running. Mutation = restore RecordFormPage.tsx at the base blob. PROVED ON DISK BEFORE MEASURING: git hash-object == the BASE blob exactly, and both text counts moved ('buildExpressionUser(user)' 1->0, \"role: user.role ?? 'user'\" 0->1); a script-level guard voids the run if either check fails. Restore was BY HASH against the PINNED COMMIT 3e8d63500 -- never origin/main -- confirmed by hash-object back to the pin blob AND an empty `git diff HEAD`; the script carried trap '<restore>' EXIT INT TERM with absolute paths under an explicit REPO_ROOT. NO dist sits between mutation and assertion on this leg: the root vitest config aliases every @object-ui/* to packages/*/src and the view is imported by relative path, so the suites read the mutated source directly; no rebuild was needed or done. Predicted RED and observed RED, 6 of 6: shape parity signed-in ('expected { name: Ada, ...(3) } to strictly equal { id: u_admin, name: Ada, ...(4) }'), shape parity signed-out, isPlatformAdmin gate vs non-admin ('expected [ name, plan, ...(2) ] to not include plan' -- the admin-only field WAS on screen for a sales clerk, i.e. the fault failed OPEN), ctx.user.id gate, signed-out isPlatformAdmin gate, and the ratchet, which named both offending sites (RecordFormPage.tsx [ExpressionProvider] and [createExpressionEvaluator]). Predicted GREEN and observed GREEN: 'grants the isPlatformAdmin gate to a platform admin' (a fault and a true are indistinguishable at the call site, which is why the excluded-user cases carry the pin), both published-name pins, and -- the load-bearing one -- ALL of RecordFormPage.predicateScope.test.tsx, i.e. #6493's own pins, because the hand-rolled shape still had `positions`. That is precisely why this card had to exist.",

Surfaced by this card's own shape pin. Not fixed here: it changes the normaliser's declared output, which AppContent.expressionUserShape.test.ts pins, and the right shape is a decision (`id: null` vs `undefined` -- rejected by #5424's precedent -- vs absent), so the in-scope-repair exemption fails on 'mechanically pinned by existing evidence'. Today's behaviour is PINNED in a case named `RECORDS:` so the follow-up has a red test to turn green.",
    "filed as #6535: 6 of the 8 views AppContent declares lazy() are in the EAGER closure anyway (DashboardView, PageView, RecordDetailView, RecordFormPage, ReportView, SearchResultsPage; only ComponentNavView and ObjectDataPage are not). The entry chunk imports them STATICALLY through the package barrel -- verified in the built output: assets/index-BE-9TM9n.js contains `from\"./RecordFormPage-D5jJD1gx.js\"`. Observational, labelled `finding`. It does NOT change this repair -- the source-graph edge the budget gate weighs is real either way and the leaf module is right regardless -- but the adjacent belief that these chunks are off the first-paint path is measurably false."
