#345 Gate Application Answer Writes and Submission on Application Status

[b-at-neu]

Closes #345

Summary

• createOrUpdateApplicationAnswer and submitApplication scoped ownership-only checks — a submitted application (or any status past draft/withdrawn) could be silently rewritten and resubmitted from /positions/[id]/apply, resetting status/submittedAt.
• Both actions now gate their read/write on APPLICANT_EDITABLE_APPLICATION_STATUSES (draft, withdrawn) — the sanctioned withdraw→edit→resubmit path stays open, everything else is refused with a user-facing message.
• The apply page becomes the primary UI gate: a non-editable application renders a read-only "You've already applied" card instead of the editable stepper, so the server gates are defence-in-depth for stale tabs / direct action calls rather than the everyday path.

Changes

• lib/constants.ts — added APPLICANT_EDITABLE_APPLICATION_STATUSES as the single source of truth for both actions and the apply page (kept distinct from NON_REVIEWABLE_APPLICATION_STATUSES, which encodes a different rule for reviewers).
• prisma/actions/applications.ts:
  • createOrUpdateApplicationAnswer now does a findFirst scoped to { id, userId, deletedAt: null }; a miss throws (IDOR-style, unreachable from the UI), a non-editable status returns { error } with actionable copy.
  • submitApplication runs the same status check before the window/required-answer checks (so the most relevant message wins), and the final write is an updateMany scoped to the editable statuses — count === 0 returns a distinct "refresh" message for the concurrent-submit race. Return type narrowed to ResponseType<void>.
  • Extracted the repeated refusal copy to a module-local constant (3 uses).
  • Corrected the stale createDraftApplication comment that claimed a gate existed which was never written.
• app/(main)/(auth)/positions/[id]/apply/page.tsx — branches on APPLICANT_EDITABLE_APPLICATION_STATUSES to render either the editable ApplicationStepper or a read-only "already applied" card (status badge, submitted date, status-appropriate copy, links to My Applications / back to the position). PageHeader description is omitted for the non-editable case.
• components/features/application-stepper.tsx — the onSave passed to ApplicationQuestion now returns the action's { error } message instead of collapsing it into a bare throw.
• components/features/application-question.tsx — onSave widened to Promise<string | void>; a resolved string toasts the exact refusal message and keeps the destructive border without advancing the "saved" ref (so a retry is still attempted later); a throw keeps the existing generic toast.

Testing plan

• Apply to an open position as an applicant, answer required questions, Submit → toast "Application submitted", redirect to /applications, status Applied.
• Revisit /positions/<id>/apply for that application → "You've already applied" card with the Applied badge and the withdraw instruction; no form fields; both links navigate correctly.
• As an admin/manager set that application to Accepted, then revisit the apply URL → same card, copy reads "has been Accepted and can no longer be edited", no withdraw instruction.
• Withdraw the application from My Applications, open /positions/<id>/apply → the editable stepper renders, blurring a field autosaves, Submit succeeds → status Applied with a fresh submitted date (withdraw→edit→resubmit still works).
• Stale tab, answer write: open the apply form for a draft in tab A; submit it in tab B; back in tab A blur a field → toast "This application has already been submitted. Withdraw it to make changes." and the field shows its error border.
• Stale tab, submit: in that same tab A press Submit → toast "This application has already been submitted. Refresh to see its current status."
• Repeat the stale-tab blur check with the application set to each of Reached out, Interview scheduled, Reviewing, Rejected via the reviewer status control → refused every time; verify in the reviewer view that no answer text changed.
• Draft is unaffected: create a draft, navigate away, return via My Applications → Continue → answers persisted, both steps still autosave, Submit works.
• Close the position, then hit /positions/<id>/apply directly → still redirects to /positions (unchanged).
• Attempt to submit/answer via a forged/unauthorized applicationId (not owned by the caller) → throws (unreachable from the gated UI), not a user-facing { error }.
• Applicant with an incomplete profile still sees the "Complete your profile first" gate (unchanged, evaluated before the editability branch).

Automated checks

• npm run prettier:check — pass
• npm run eslint:check — pass
• npm run tsc:check — pass
• No test runner exists in this repo (no vitest/jest); the Testing plan above is the manual verification matrix, per the issue's own note.

Notes

• APPLICANT_EDITABLE_APPLICATION_STATUSES shares members with NON_REVIEWABLE_APPLICATION_STATUSES today but encodes a different rule (what the applicant may edit vs. what a reviewer may not act on) — kept as separate constants intentionally, not aliased.
• Out of scope, per the issue: withdraw gating for terminal statuses (Block Withdrawing Accepted or Rejected Applications #346) and reopen/resubmit validation (Validate Position Status, Window, and Deletion in Reopen #347).

R1-L1 🟡 Low — components/features/application-stepper.tsx#L354 — the "Use profile answers" revert loop still toasts the generic "Failed to revert some answers" when createOrUpdateApplicationAnswer returns the new editability { error } (e.g. a stale tab reverting after the application became non-editable) — inconsistent with the onSave/blur path this PR upgraded to surface the exact refusal sentence. Fix: when a results entry carries a specific { error }, toast that message (mirroring the onSave path) instead of the generic copy.

R1-C1: pushed and re-checked, but the Vercel deployment still fails (dpl_F6NhDwtpJAsfPFQsnA1iozMQABg9). Local prettier:check/eslint:check/tsc:check/next build all pass on this branch, and the immediate parent commit on dev deploys cleanly, so this isn't a regression introduced by this PR's diff. Sibling PRs #409 and #410 (unrelated code) started failing the same way in the same ~20-minute window today, while #407/#408 (built earlier today) still show green — pointing at a transient/shared Vercel or Neon preview-branch provisioning issue rather than app code. No tool access to Vercel deployment logs to confirm further; flagging for human follow-up if it persists past the next cycle.

skipped R2-C1 · 63033b7

R2-C1: rebased onto dev and force-pushed (new commit 63033b7, since dev had moved since the last push) to get a fresh Vercel deployment attempt — it failed again (dpl_GgeskJBUbgBbSdhPVodcfUNC6d5f), going pending → failure in ~10 seconds per the commit status timestamps, far too fast for npm ci && prisma migrate deploy && next build to have actually run. prettier:check/eslint:check/tsc:check and a local next build all still pass on this branch (the only local build error is an unrelated, pre-existing NEON_AUTH_BASE_URL env-var miss on /api/auth/[...path] that also reproduces identically on plain dev in this sandbox, so it isn't this PR). The 10-second fail time points at the preview-build's pre-build step in vercel.json (prisma migrate deploy against DATABASE_URL_UNPOOLED, gated on VERCEL_ENV=preview) rather than the app build — i.e. a provisioning race in the Neon Previews Integration wired up by #403 (merged the same day these failures started), not this PR's diff. Sibling PRs #409/#410 have since gone green on Vercel, but this branch has now failed 3 consecutive deployments across 2 cycles (Cycle 1: Gin4cmCYfHqA1TKnaTxHoXhAaoVM, Cycle 1 fix-push: F6NhDwtpJAsfPFQsnA1iozMQABg9, this push: GgeskJBUbgBbSdhPVodcfUNC6d5f) — no code fix available from this diff, and no tool access to Vercel build logs, Neon console, or vercel/npx vercel (denied by policy) to confirm further. Flagging again for human follow-up (Neon console: confirm a preview branch + DATABASE_URL_UNPOOLED exist for 345-gate-application-answer-writes-and-submission) if it persists past the next cycle.

fixed R5-C1 · beb7a04 · rebase: prisma/actions/applications.ts (combined dev's shared format-revalidation refactor with this PR's status-gating check — both additive, no logic dropped)

R5-C1 (Vercel check failing) was infrastructure (stuck preview branch during a Neon-quota window per #412), not a code defect — no source fix was applicable or applied. Per human instruction, rebased onto origin/dev (now past #419's merge, which shipped run-neon-check + the refresh branch recovery path) to force a fresh preview-branch deployment. Result: Vercel now passes ("Deployment has completed"), confirming the stuck-branch theory rather than a regression. All other checks (run-linting-check, run-prettier-check, run-tsc-check, run-neon-check) also pass.

Rebase conflict: prisma/actions/applications.ts had one hunk in createOrUpdateApplicationAnswer — dev (via a later PR) refactored the question fetch into a single shared, format-aware lookup (select: { type, format } + short-answer format re-validation), while this PR added the APPLICANT_EDITABLE_APPLICATION_STATUSES status gate right after requireOwnership. Confirmed via merge-base diff that these are two independent, additive changes to non-overlapping concerns (this PR never touched the per-branch fetch/upsert bodies that dev rewrote), so combined them: status gate first (consistent with submitApplication's existing "status check wins" ordering), then the shared format-aware fetch. No logic dropped from either side; prettier:check/eslint:check/tsc:check all pass on the merged result.

Revision — rebase

Human-directed rebase onto origin/dev (no review findings to address; latest review is Cycle 6 · approved). Conflicts in 3 files, all auto-resolved (no ambiguous/semantic or never-touch conflicts):

• lib/constants.ts — adjacent insertions (dev's new one-line comment on NON_TERMINAL_APPLICATION_STATUSES vs. this PR's new APPLICANT_EDITABLE_APPLICATION_STATUSES constant). Kept both; compressed the new constant's comment to the current one-line comment standard.
• prisma/actions/applications.ts — dev added short comments at spots this PR also touches; this PR's status-gating logic (APPLICANT_EDITABLE_APPLICATION_STATUSES checks in createOrUpdateApplicationAnswer/submitApplication) was untouched by dev, so kept it and merged comments down to one line each. In submitApplication's tail, kept this PR's updateMany + race-guard logic (dev still had the pre-PR update/return updated shape) and adopted dev's now-standard 3-call revalidatePath('/my-applications')/'/applications'/'/positions', 'layout' pattern used elsewhere in the file.
• components/features/application-question.tsx — onSave's signature conflict (dev: Promise<void>; this PR: Promise<string | void> for refusal messages already consumed by save()). Kept this PR's signature (required for the code to type-check) and compressed both comments to one line each.

All comment edits made during resolution follow the current ENGINEERING.md §7 comment-discipline rule (one line by default, no provenance refs).

R7-L1 🟡 Low — this read stays a bare findUnique({ where: { id } }) + requireOwnership, unlike every other application-by-id query in this file (updateApplicationStatus, withdrawApplication, reopenApplication, deleteDraftApplication, and submitApplication's own write below), which all scope deletedAt: null. Application.deletedAt is currently never set by any action, so this has no live exploit path today, but it's an inconsistency with the plan's Data & contracts section (which specified findFirst scoped to { id, userId, deletedAt: null }) and with the file's own convention. Fix: switch to findFirst({ where: { id: applicationId, userId: currentUser.id, deletedAt: null }, select: { positionId: true, status: true } }) and drop the now-redundant requireOwnership call (miss → throw, matching the IDOR-miss pattern used elsewhere in this file), mirroring submitApplication's read for consistency.

Revision — comment-discipline cleanup

Applied the current ENGINEERING §7 comment bar (rare, one line by default, no provenance refs) across this PR's diff. 50c2bdb

7 comments condensed to one line (including removing an ENGINEERING §1 citation on APPLICATION_NOT_EDITABLE_MESSAGE in prisma/actions/applications.ts); 1 left as a rare 2-line exception (the submitApplication scoped updateMany — explaining both what it's scoped to and why (closing the check-then-write race) didn't compress into one line without losing the invariant); 0 deleted outright — every comment carried a genuine non-obvious fact, just needed compression. R7-L1 (the findUnique/requireOwnership consistency nit) is untouched — out of scope for this cleanup pass.

Pipeline Escalation

Rebase of 345-gate-application-answer-writes-and-submission onto origin/dev hit a genuine same-function conflict that needs the original author's judgment — not a mechanical rebase issue.

File: prisma/actions/applications.ts — submitApplication

Since this PR's last rebase, PR #420 (355-keep-drafts-submittable-after-global-question) merged into dev and substantially refactored the same function:

• dev's side (Keep In-Progress Drafts Submittable After a Global Question Is Added #355): wraps the whole read-check-write in prisma.$transaction, replaces the old findMissingRequiredAnswers read-only check with a syncGlobalAnswersFromProfile(tx, ...) backfill (writes missing global answers from the profile inside the transaction) plus a separate hasUnansweredRequiredPosition check, and writes the final status via tx.application.update (no status filter on the write, since dev's tree doesn't have this PR's gating yet).
• this PR's side (#345 Gate Application Answer Writes and Submission on Application Status #411, commit 835255d): adds the core feature of this PR — gates the whole flow on APPLICANT_EDITABLE_APPLICATION_STATUSES (application.status checked right after the position-deleted check, before the window/required-answer checks), and changes the final write from a plain update to a status-scoped updateMany (status: { in: APPLICANT_EDITABLE_APPLICATION_STATUSES }) specifically to close a check-then-write race window between the read and the write, returning a distinct "already submitted, refresh" error when count === 0.

Both sides touch the same function body, the same read, and the same write. Taking either side whole drops real logic from the other:

• Taking dev's side drops this PR's entire status gate — the reason this PR (issue Gate Application Answer Writes and Submission on Application Status #345, "Gate Application Answer Writes and Submission on Application Status") exists.
• Taking this PR's side drops dev's newer transactional backfill (syncGlobalAnswersFromProfile) and hasUnansweredRequiredPosition refactor from Keep In-Progress Drafts Submittable After a Global Question Is Added #355.

Merging correctly requires deciding:

1. Where the APPLICANT_EDITABLE_APPLICATION_STATUSES gate slots into the now-transactional check order (before/after the backfill?).
2. Whether the backfill (syncGlobalAnswersFromProfile) should still run for a non-editable-status application, or whether the gate should short-circuit before it runs.
3. How to re-implement the check-then-write race guard (previously a status-scoped updateMany outside a transaction) now that the read+write both live inside tx — e.g. does the final write become a status-scoped tx.application.updateMany, and does the count === 0 branch still make sense inside a transaction that already re-read the application via tx.application.findUnique?

This needs the PR author's (or a maintainer's) judgment, not an autonomous merge. Both conflicting hunks are preserved unresolved; the rebase has been aborted and the branch left untouched at its last pushed commit (f3d56aa, mergeable against the previous dev tip but now stale again since #420 merged).

Not auto-resolved; not pushed.
