Purity seals in the official feature recap
The developer explicitly names purity seal collectables in the sequel’s feature update. That is the strongest source for retaining the category in this guide. It does not include a complete numbered inventory or a statement of every collectible effect.
The same announcement also describes the broader branching campaign. Those campaign features supply context for exploration across the game. They do not establish how many seals a selected route can contain.
Seals and secrets are distinct in demo coverage
Nuka Kitten’s collected demo captions mention secrets and seals separately in a completion report. A different creator also uses separate seal labels in the chapter list. Those sources corroborate relevant preview terminology without proving a complete collection run.
The official demo announcement independently confirms secrets. The secrets overview keeps its coverage focused on that exploration scope. A seal timestamp should therefore not be converted into a total of all hidden pickups.
What the available timestamps establish
The creator’s chapter metadata gives locations within a demo recording where seals are discussed or shown. It helps identify a viewing lead. It does not reproduce the route, verify a reward or establish that the inventory is complete.
The walkthrough page explains the two-level preview context. The mission list page distinguishes those demo labels from the full branching campaign. That prevents a preview collection lead from being presented as a retail completion table.
No inferred collectible rewards
The dossier does not establish exact seal effects or a complete reward list. It also does not show that a particular collectible unlocks an achievement or cosmetic. The achievement page retains only the platform support actually confirmed by the stores.
