Problem

An approved project retains prior_approved_hours as banked Restoration Energy while a new update goes through review. The project edit route prevented changing level and sidequest_id only at status approved, but status needs_changes (including during approved update cycles) permitted both. lifetimeRe() weights banked old hours using those mutable fields, allowing a previously approved 20h Tier 1 project's old 250 RE to appear as 500 RE after a Tier 4 edit without approval, increasing the rate on unrelated future ships.

Review dashboard tier-setting paths were also able to regrade previously approved work during updates.

Changes

• Centralize mustPreserveApprovedProjectTerms(status, isUpdate) in each independently built app.
• Lock tier and Trial link when editing either an approved project or an is_update project in any review state; first-time projects can still choose tier while fixing requested changes.
• Guard both reviewer regrade paths (verdict form and standalone tier control), including same-state checks on their writes.
• Use precise status/is_update compare-and-set in the player's edit route so a stale edit cannot cross into a newly approved state.
• Add tests for update review states, original hours retention, and new-submission behavior in both apps.

Intentional limitation

PIXL currently stores only a single tier and Trial link per project, including historical approved hours. Until there is a versioned per-approval model, an update must not be regraded at any stage; otherwise the prior approval's RE changes. Reviewers should use the original tier for update submissions.

Validation

Regression unit tests added to both earnedProject.test.ts files; CI pending. No production database changes. This is a preventative patch, not a claim that Eraxty's separately reported issue has an identical cause.
