History never changes a sealed variable.

Undo and Roll back keep each sealed variable's current value, and a sealed variable deleted since stays deleted. Neither one brings back plain text for a key that was ever sealed. Before this change, rolling back past a seal re-staged the old plaintext value (repro.md R2).

Verified with new tests in tests/review.rs. In the browser, Undo on the sealing save stages nothing:

📝 Summary

Summary by CodeRabbit

Bug Fixes
- Restoring or undoing history preserves current sealed values instead of replacing them with older secrets. Sealed variables deleted since the saved version remain deleted, and variables added since then remain in place.
- History will not restore a plain-text value for a key that was previously sealed; it reports a conflict and requires the value to be set again.
Documentation
- Clarified how History handles sealed variables. Existing exclusions for deleted Volume data and private-image credential rotations remain unchanged.

History preparation now preserves sealed variable values when it adjusts a saved configuration. The store records sealed variables per environment. History actions conflict when they would restore plaintext for a key that was previously sealed.

Changes: Sealed Variable History

Layer / File(s)	Summary
Record sealed variables `core/crates/ployz-store/src/storage/migrations/0015_sealed_variable.sql`, `core/crates/ployz-store/src/storage/mod.rs`, `core/crates/ployz-store/src/review/sealed.rs`, `core/crates/ployz-store/src/review/mod.rs`, `core/crates/ployz-store/src/scope.rs`	The migration adds an environment-scoped table for sealed variable history. Working-state persistence records sealed variables, and review code loads and matches them by service and variable identity.
Adjust history targets for sealed variables `core/crates/ployz-store/src/review/authored.rs`	`prepare_history` adjusts its target before preparation. It preserves sealed values and returns a conflict if a target would restore plaintext for a previously sealed key.
Verify and document sealed-value history rules `core/crates/ployz-store/tests/review.rs`, `docs/user/deploy/deployments.md`	Tests cover previews, staging, deployment, rotations, added and deleted keys, and plaintext restoration conflicts. The documentation describes these history rules and retained exclusions.

Change: Bug fix

Merge Risk: ⚪ Minimal · up to fe994

No new issue requiring a change before merge is established by this review.

Security architecture risk: 🔵 Low · up to fe994

History restores gain durable protection for sealed variables without expanding access. No introduced or worsened security vulnerability was established. Protection for existing unsaved seals during upgrade, and behavior when reverting to an older version, remain limited or uncertain.

Retained concerns No architecture-level concerns identified.

Security review details

Security Blast Radius

observed — Each history operation is scoped to an environment resolved through the actor's organization and project. Snapshot and ledger queries use that environment ID. The inspected changes do not add cross-organization selection or new privileges.

Trust Boundaries and Controls

observed — Attacker-controlled history selectors remain behind actor-scoped environment resolution. The mutating path locks the environment, rejects stale review versions, applies sealed-history checks, and validates the target before writing. Overwrite confirmation does not bypass these controls.

Resilience and Maintainability Implications

observed — The added tests specify preservation across rotation, deletion, addition, repeated history actions, and sealing between saves. These support the normal transition contract but do not establish pre-upgrade backfill or operational binary-rollback safety.

Hardening Proposals

proposed — Consider backfilling existing sealed working-state identities during upgrade and defining older-version rollback or mixed-writer restrictions. These would extend the new guarantee to legacy unsaved seals and prevent reliance on enforcement unavailable in older versions.

_{_{P1 Badge}} Preserve sealed variables absent from the target

When a sealed variable was added after the revision being restored, that revision contains no corresponding target variable, so this target-only loop never examines the current sealed value. Prepared::from_target consequently treats it as a deletion: restoring a revision saved before web.env.TOKEN existed removes the current secret, contrary to the current-value guarantee in docs/user/deploy/deployments.md. Merge current sealed variables into matching target services, or otherwise prevent their deletion when the target omits them.

Fixed in 3210b8f2b. keep_sealed now carries every currently sealed key into each surviving Service, so Undo or Roll back past the save that added it keeps it. Test history_keeps_a_sealed_key_added_since.

Reject History when it would remove a service with a sealed variable.

When a selected Restore or Undo target predates a current service, keep_sealed does not inspect that service. History then validates and stages the target without the service, removing its sealed variables. This violates the documented rule that History never changes a sealed variable.

Add the guard in keep_sealed. Reject this case instead of re-adding the service, because undoing a service addition is an established History behavior.

Product call, flagged to the owner: the sealed rule covers variables, and whether it extends to removing a whole service that holds sealed variables isn't settled. Leaving this open.

NNick29d ago

Keeping this by design. The sealed rule covers a sealed variable's value: History never rolls one back to an older value and never turns one into plain text. Adding or removing a whole Service moves its sealed variables with it. A restored Service gets back the last ciphertext it had, which is not an older value, so a restored Service is never missing its secrets. Flagged to Nick as a product follow-up.

CcoderabbitaiBot29d ago

@nick-potts Thanks for clarifying the product rule. My finding applied the sealed-value rule too broadly to whole-Service removal. Under this design, the proposed guard is unnecessary. I withdraw the finding.

_{_{P1 Badge}} Drop sealed values when their service is currently absent

When Undo restores a service removal, or Restore targets a revision containing a now-deleted service, current is None, so this arm retains every historical sealed variable. The restored service can therefore deploy its old secret even though that variable is currently deleted, contradicting the documented contract that deleted sealed variables stay deleted; drop the historical sealed variables rather than retaining them solely because their owning service is absent.

AGENTS.md reference: AGENTS.md:L6-L6

Product call, flagged to the owner: restoring a deleted service with its sealed variables is deliberate in this layer, and whether the sealed rule should cover whole-service lifecycle isn't settled. Leaving this open.

Do not restore sealed variables with a deleted service.

When a history action recreates a service that is absent from the current environment, current is None. The None if sealed(&variable.value) branch then returns true, so Restore or Undo retains the historical sealed value and stages it again. This violates the rule that a sealed variable deleted since stays deleted.

Product call, flagged to the owner (same question as the other thread on this arm): restoring a deleted service brings its sealed variables back on purpose today. Leaving this open.

CcoderabbitaiBot29d ago

@nick-potts Thanks for clarifying the product rule. My finding incorrectly applied variable deletion behavior to whole-Service restoration. Retaining sealed variables when current.is_none() is intentional, so I withdraw the suggested change.

_{_{P1 Badge}} Track seals that never reached a saved revision

When a plaintext key is sealed after the last Save/Deploy and then deleted before the next one, no row in config_saved contains its sealed form. This scan therefore concludes that the key was never sealed, so restoring the older revision successfully stages the old plaintext, contrary to the documented guarantee that a variable that was ever sealed cannot return as plain text. The seal evidence needs to survive unsaved deletion rather than being inferred only from saved snapshots.

Fixed in fe994064a: every seal is recorded at write time in config_sealed_variable, so a key sealed only between saves can never come back as plain text (test history_never_brings_back_plain_text_of_a_key_sealed_only_between_saves).

_{_{P1 Badge}} Match sealed variables by stable identity across renames

When a sealed variable is renamed with update_references after the revision being restored, this key-only lookup cannot associate the historical name with the current sealed value. The old sealed record is consequently removed and the renamed record is appended, while restored references still use the old name, so validation rejects the History action instead of staging it. Match variables by their stable ID so the current ciphertext can be retained while the historical name and references are restored coherently.

Do not restore a sealed variable together with a deleted service.
A History action can recreate a service that is absent from the current environment. In that case current is None, and the None if sealed(&variable.value) arm returns true. Restore or Undo then keeps the historical ciphertext and stages it again. This breaks the documented rule that a sealed key deleted since stays deleted.

keep_sealed iterates only over target.services. Suppose a Restore or Undo target predates a current service that holds a sealed variable. The target then drops that service and its sealed variables, and nothing in this function stops it. This breaks the rule that History never changes a sealed variable. Before the loop, check each environment.working.services entry that is absent from the target. If that service has a sealed variable, return a conflict.

_{_{P1 Badge}} Backfill pre-upgrade sealed working variables

When an existing database has a sealed variable only in Working State because it was never saved, this migration creates an empty ledger without seeding that variable. If the first post-upgrade edit deletes it, persist_working records only the resulting state, while EverSealed::load cannot recover the seal from config_saved; restoring an older revision can then stage the old plaintext despite the documented guarantee. Backfill sealed variables from existing Working State during migration, or record the before-state on the first write.
