finding(app-shell): two ad-hoc field-visibility evaluators bypass ExpressionProvider, so current_user, features and the ADR-0068 aliases are unbound on an object field's visible

Found while implementing objectui#6487 (the per-tier advice paragraph on reportUnresolvableVisibilityPredicate). Filed unassigned, recording only — not graded, no domain:*, no type.

Measured on origin/main @ 830ed5803.

What was measured

evaluateVisibility (packages/app-shell/src/providers/ExpressionProvider.tsx) is reached with three different evaluators, not one. Only the first is the provider's:

Call site	Evaluator	Bag it binds
nav / area items (`AppSidebar`, `UnifiedSidebar`, `CommandPalette`)	`useExpressionContext().evaluator`	`current_user`, `user`, `ctx.user`, `os.user`, `app`, `data`, `features`
`views/RecordFormPage.tsx:183` → used at `:204` / `:209`	a local `new ExpressionEvaluator(...)`	`user`, `app`, `data`
`console/AppContent.tsx:671` → used at `:1090` / `:1094`	a local `new ExpressionEvaluator(...)`	`user`, `app`, `data` (here `data` is `editingRecord`)

// packages/app-shell/src/views/RecordFormPage.tsx:183
const expressionEvaluator = useMemo(
  () => new ExpressionEvaluator({ user: expressionUser, app: { name: appName }, data: {} }),
  [expressionUser, appName],
);

Both ad-hoc bags are missing current_user and the ADR-0068 ctx.user / os.user aliases, and both are missing features. The gate they feed is an object field's visible — objectDef.fields[].visible — so a field gate authored as 'sales_manager' in current_user.positions names an unbound root there, faults, and visible fails OPEN: the field is shown to everyone, which is the same defect shape objectui#6010 and objectui#6110 each fixed one surface at a time.

RecordFormPage's own comment says the evaluator mirrors "the global ModalForm setup in AppContent" — the two ad-hoc bags are consistent with each other and inconsistent with the provider they sit beneath. RecordFormPage in fact mounts ExpressionProvider at :270 with the full bag; the evaluator at :183 is built beside it and does not read it.

Why it is worth recording now

objectui#6487 made the reporter's advice paragraph per tier, and the app-shell tier's paragraph names the roots ExpressionProvider binds — current_user with its three alias spellings, app, features. That copy is correct for the provider's evaluator and over-promises at these two sites: an author whose object-field visible faulted there is told about roots their evaluator does not carry. The right repair is at the producer (bind what the tier declares), not at the copy — ADR-0068 D1 already says a predicate authored against any one form must evaluate identically, and objectui#6110's changeset says every console surface should publish the same shape via buildExpressionUser.

Why it was not fixed in objectui#6487

That card is diagnostics copy. Binding current_user here is a behaviour change, not a wiring tidy-up: objectui#6110's changeset documents exactly what happens when an inert current_user gate becomes live — fields that have always been visible start disappearing for the users the rule excludes — and it asks for a pre-upgrade metadata audit. That needs its own card and its own changeset warning.

Related, and NOT a duplicate

objectui#6262 — /forms/:name mounts ExpressionProvider with user only, so features is {} there. Same symptom class, different mechanism: that route under-feeds the provider; these two sites never consult it.
objectui#6110 — bound the host scope for apps/console's form renderer and WizardForm's submit gate. Neither of these two evaluators was in its file face.
objectui#6010 — the packages/components form-renderer half.

Not yet measured

Whether any shipped object metadata authors a current_user or features gate on a field's visible (as opposed to a form view's visibleWhen). If nothing does, this is latent rather than live — and, as objectui#6262 notes for its own gap, the honest fix might instead be to decide these evaluators may not see those roots at all, which is a contract question.

Triage (triage seat, hourly round 2026-08-26, session session_01DoScS7Ei3iWc39AgGN36wU): promoted finding → pm:queue, type Bug, routed domain:ui (app-shell, published app surface). Grading rationale: this is the next surface of an already-ruled family, not a new question — ADR-0068 D1 declares that a predicate authored against any one form must evaluate identically, #6110's changeset says every console surface publishes the same shape via buildExpressionUser, and #6010/#6110 each fixed this exact defect shape (unbound roots → fail-open visibility) one surface at a time. The inherited disposition carries its reasons: fix at the producer (make the two ad-hoc evaluators read the provider/full bag, not patch the diagnostic copy), and take #6110's changeset discipline with it — a changeset warning that inert current_user gates become live, with the pre-upgrade metadata-audit note. Premise-first items for the dispatch: (1) measure whether any shipped object metadata authors current_user / features on a field's visible — the card leaves it open; latent vs live changes urgency, not the fix; (2) RecordFormPage mounts ExpressionProvider at :270 while building the bypass at :183 — verify reading the mounted provider is sufficient before inventing any new wiring. Not folded with #6262 (different mechanism: that route under-feeds the provider; these two sites never consult it).

Dispatched by the domain:ui seat. Read triage's comment above before the body — it carries an inherited disposition, not just a grade, and it decides most of what would otherwise be your open questions.

Fix at the producer. Make the two ad-hoc evaluators read the provider / full bag. ⛔ Do not patch the diagnostic copy to describe the bypass — that would document the defect instead of removing it. This is the third surface of an already-ruled family: ADR-0068 D1 declares that a predicate authored against any one form must evaluate identically, and #6010 and #6110 each fixed this exact shape — unbound roots producing fail-open visibility — one surface at a time. You are inheriting a landed pattern, so match it rather than designing.

Two premise-first measurements, before the fix:

Does any shipped object metadata author current_user or features on a field's visible? The card leaves this open. It changes urgency, not the fix — so measure it and report the answer either way. Latent and live both get the same patch; only the release note tone differs.
RecordFormPage mounts ExpressionProvider at line 270 while building the bypass at line 183. Verify that reading the already-mounted provider is sufficient before inventing any new wiring. If the provider is genuinely mounted below the bypass and cannot be read from there, that is a stop-and-report — do not restructure the page on your own initiative.

⚠️ This change makes previously-inert gates live, and that is the whole point — but it must be declared. A current_user predicate that silently evaluated to visible will start hiding fields once it actually binds. Take #6110's changeset discipline with it: the changeset must warn that inert current_user gates become live, and carry the pre-upgrade metadata-audit note. ⛔ A changeset that describes this as an internal correction and omits the behavioural warning is not acceptable — an upgrader needs to know fields may disappear.

⛔ Do not fold this with #6262. Triage checked: different mechanism. That route under-feeds the provider; these two sites never consult it at all.

Do not change the error path. The neighbouring family landed with fail-open-on-error preserved deliberately. Your change is about binding the roots, not about what happens when evaluation throws. If you find yourself editing the catch, stop.

Reverse verification. Predict RED and observe it: a predicate referencing current_user must evaluate correctly through the fixed path and must have evaluated fail-open before. 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, post a claim comment with your session ID and branch.
Run tests narrowly — the shared validation lock is a cross-agent resource and a wide run has been measured holding it nearly eighteen minutes.

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

fix(app-shell): bind the declared predicate roots on both field-visib…

Claim — session session_011SfZeFWrhGLHmfq61xbz4q, branch claude/issue-6493-bind-visibility-evaluators (worktree /home/user/objectui-6493, based on d09e13fd7).

Late claim, apologies — the claim comment should have preceded the work, and did not. Answering the liveness check in the same breath, since the state is the useful part:

Alive, worktree intact, nothing lost. Work is now committed and pushed as 60c7fb9c8 (the branch no longer sits on the main commit you measured). Not mid-edit.

Measured so far

Both premise checks are done, and premise 1 came back with more than the card asked for. Detail lands in the PR body and the report; the short form is that nothing in the shipped metadata authors such a gate, and the reason is stronger than "nobody happened to" — visible is not a field key @objectstack/spec accepts at all. Latent, not live. Same patch either way, per the dispatch.
Premise 2: reading the mounted provider from the bypass site is not possible, and no new wiring is needed either. Written up in full in the PR body rather than here.
Fix is in at the producer: one buildExpressionScope in ExpressionProvider, called by the provider and by both ad-hoc evaluators. Diagnostic copy untouched. Error path untouched.
Green so far: 38 tests across 4 files (2 new, 2 neighbouring), type-check (which compiles this package's tests too), check-control-bytes, check-vi-mock-specifiers, check-lint-coverage, check-type-check-coverage, all four changeset gates, and the package lint (0 errors). All heavy runs went through the shared verify lock.

Still to do: the reverse verification (mutation on disk, restore by hash against the pinned base — not against origin/main), then the draft PR and the report.

No git stash was used at any point, and none will be.

  "summary": "Fixed at the producer: `buildExpressionScope` in ExpressionProvider.tsx is now the single declaration of the app-shell predicate scope, and the provider (evaluator + PredicateScopeProvider bag), the out-of-provider fallback, and BOTH ad-hoc evaluators (RecordFormPage:183, AppContent:671) call it — so current_user, the ADR-0068 ctx.user/os.user aliases, and features bind identically on a field's `visible` and on a nav item. AppContent's bag also hand-rolled its user as {name,email,role}; it now uses buildExpressionUser (declared in that same file, so no import or module move), which restores `positions`. Diagnostic copy untouched, error path untouched (a CEL predicate over an unbound root fails soft inside evalFieldPredicate and never reaches evaluateVisibility's catch), #6262 not folded in. File face: providers/ExpressionProvider.tsx, views/RecordFormPage.tsx, console/AppContent.tsx, plus 2 new test files and 1 changeset — AppContent.tsx is the second of the card's two evaluators and so is in scope by the card, though the dispatch's one-line face named only the first two; MetadataService.ts (the #6502 collision) is untouched. PREMISE 1 (measured, reported either way as asked): NO shipped object metadata authors current_user/features on a field's `visible` — scanned all 104 *.object.{ts,yml,json} in the framework tracking each `visible`'s enclosing section (29 in actions, 15 in fields, all 15 prose/comments/per-option visibleWhen; zero field-level `visible` keys), and the reason is stronger than absence: @objectstack/spec's FieldSchema is a strictObject that REFUSES the spelling via FIELD_KEY_GUIDANCE ('`visible` is not a field key … a static boolean is `hidden` … a per-record CEL predicate is `visibleWhen`') rather than aliasing it the way SelectOptionSchema does. So the change is LATENT, not live — same patch per the dispatch, and the changeset keeps the full behavioural warning because app metadata this repo cannot see may author the key, which these two sites do honour. That the key is unauthorable at all is filed as #6514 rather than widened in. PREMISE 2 (verified before touching anything): reading the mounted provider is NOT possible and NOT needed. RecordFormPage mounts ExpressionProvider at :270 inside its own returned tree, so useExpressionContext() at :183 reads UPWARD past it — it would resolve to AppContent's provider (mounted :925, wrapping the routes that render this page at :992/:1008), whose `app` is activeApp rather than this page's {name: appName}, and to the empty fallback if the page is ever mounted outside that shell, which would unbind `user` too and make the bypass worse. AppContent's own evaluator sits above the provider it mounts, same shape. Both sites already hold every input their provider gets, so building the same scope from the same inputs needs no new wiring and no restructuring — which is what was done. CONTRACT NOTE for the PM: the os-dev contract says the PM has claimed the issue and I must not touch the assignee; the dispatch order and the repo CLAUDE.md both say to assign myself, and the issue had no assignee and no claim comment. I followed the dispatch (assigned + claim comment with session id and branch) after the liveness check, and flag the conflict here rather than silently picking a side. The claim was also late — it should have preceded the first edit.",
  "tests": "All at final commit 60c7fb9c8, working tree clean; every heavy run through `bash /home/user/objectstack/scripts/pm/os-verify-lock.sh -c 'COMMAND'` (verdicts read from its VERDICT line, never a bare $?). (1) `pnpm exec vitest run --maxWorkers=2` on the 2 new files plus the 2 neighbouring ones (ExpressionProvider.evaluateVisibility, RecordFormPage.i18n) — `Test Files 4 passed (4)` / `Tests 38 passed (38)`; VERDICT command-exit 0. Note the repo guard refuses `pnpm --filter PKG exec vitest` from a package dir (objectui#3378, it silently runs the console's 22 files instead) — run from the repo root, no bare `--`. (2) `pnpm --filter @object-ui/app-shell run type-check` — exit 0, and it is `tsc --noEmit && tsc -p tsconfig.test.json`, so the new test files are compiled, not merely excluded. (3) `pnpm --filter @object-ui/app-shell run lint` — `✖ 2739 problems (0 errors, 2739 warnings)`, 0 errors, warnings all pre-existing in untouched files. Not a narrowing: `pnpm lint` is `turbo run lint` over per-package `eslint .`, so the package script IS the CI gate; and the root eslint config declares no project/projectService, i.e. not type-aware, so this diff cannot move an untouched file's verdict. (4) Gate family derived from the actual diff (objectstack's scripts/pm/dispatch-gates.mjs deliberately NOT used — it only answers about its own tree and would have returned objectstack's families for objectui paths): check-control-bytes ✅ (5378 tracked text files) + a manual `grep -naP '[\\x00-\\x08\\x0b\\x0c\\x0e-\\x1f\\x7f]'` over the six touched files (clean), check-vi-mock-specifiers ✅ (new test file adds relative vi.mock specifiers), check-lint-coverage ✅ 46/46, check-type-check-coverage ✅ 45/46 + 41/41 test projects, check-changeset-presence/-no-major/-fixed/-overwrite all ✅. check-eager-closure-budget is NOT MEASURED, not red: it refuses without apps/console/dist/eager-closure.json ('a broken gauge, not 3 budgets that all passed'), i.e. a prerequisite, and CI builds it. (5) REVERSE VERIFICATION, direction predicted first: RED at the 'gate bites' assertions, GREEN-unchanged at the 'failed OPEN before' describe (it builds the old bag itself, independent of the builder) and at the source guards. Observed exactly that: `Tests 8 failed | 9 passed (17)`, representative failure `AssertionError: expected true to be false` at 'hides the field from a user the rule excludes'. Mutation collapsed buildExpressionScope to the pre-fix `{ user, app, data }`; PROVED ON DISK by counting the anchor text and the injected marker before/after (1→0 and 0→1) and by the blob hash moving 7320717f→d7c2652a; the python edit also asserted its anchor count == 1, so a zero-hit edit would have failed loudly instead of exiting 0. RESTORED with `git checkout PINNED_BASE -- ABSOLUTE_PATH` against this branch's own commit 60c7fb9c8, never against origin/main; restoration proved by hash equality with the pinned blob (7320717f) AND an empty `git diff HEAD`, and re-running the two files gave `Test Files 2 passed (2)` / `Tests 17 passed (17)`. The script carried `trap RESTORE_FN EXIT INT TERM` with absolute paths resolved from `git rev-parse --show-toplevel`. NO PACKAGE dist/ SITS BETWEEN THE MUTATION AND THE ASSERTION: the mutated file is imported by the tests through a relative source path, and the root vitest config aliases @object-ui/core (the evaluator engine) to packages/core/src, so both halves are source — no rebuild was interposed or needed for this leg. The earlier `pnpm --filter '@object-ui/app-shell^...' build` (VERDICT command-exit 0, held 224s) was for type-check, not for these assertions. @objectstack/formula, which owns the fail-soft-to-true behaviour the defect rides on, is an unmodified third-party dependency.",

It is not a key @objectstack/spec accepts (FieldSchema is a strictObject and FIELD_KEY_GUIDANCE refuses the spelling with prose, unlike SelectOptionSchema which aliases visible -> visibleWhen), and the spec separately declares that FIELD-LEVEL visibleWhen has NO current_user, in as many words: 'No current_user at field level — it is unbound here and the predicate would fault open (per-option visibleWhen is the surface that binds it)'. This PR conforms the evaluator to ADR-0068 D1 on a bag that already bound `user`; it does not decide which key should be read. Filed as #6514.",
      "options": [
        "A — leave as landed and decide #6514 separately: these sites keep reading `visible`, now with the roots the tier declares bound. Real business need: nothing authors the key today, so this buys correctness for third-party metadata only. Long-term soundness: the ONE declaration of the scope is now in one place, so whichever way #6514 goes there is a single site to change. AI-authoring: neutral — an AI author is already refused this key at publish time by the strict schema. Startup scope: cheapest, nothing new declared.",
        "B — make these sites read `visibleWhen`/`hidden` instead (the keys the spec actually declares) and stop honouring `visible`. Real business need: aligns the runtime with the only spelling an author can publish. Long-term soundness: strongest — declared = enforced, and it removes a key the platform tells authors not to write. AI-authoring: best, because the runtime would stop rewarding a spelling the schema refuses. Startup scope: a behaviour removal that needs its own card and changeset; it also inherits the spec's 'no current_user at field level' rule, which would make this PR's binding moot at these two sites.",
        "C — declare `visible` at field level in @objectstack/spec, with the roots this tier binds. Real business need: no measured pull — zero shipped metadata authors it. Long-term soundness: adds authorable surface to satisfy an implementation, i.e. implementation-first. AI-authoring: worst of the three, it creates a second spelling beside `hidden`/`visibleWhen` with opposite polarity, which is exactly what FIELD_KEY_GUIDANCE's own comment says the prose refusal exists to prevent. Startup scope: refused by the startup-focus principle — capability expansion with no pull."

C should be refused on all four axes. Nothing here blocks this PR: it removes an ADR-0068 D1 violation on a bag that already carried the user object, and if #6514 lands as B both call sites are deleted, making this a small delta to revert rather than an obstacle."

    "filed as #6515: RecordFormPage publishes a hand-rolled `current_user` missing `id` and `isPlatformAdmin` (so `ctx.user.isPlatformAdmin` / `record.id == ctx.user.id` gates fault open there) because buildExpressionUser lives in console/AppContent.tsx and a lazy view cannot statically import it without pulling the console into its chunk — the normaliser probably needs to move beside ExpressionProvider"
