Deployment history grew forever (STORE-04). Every deploy, promotion, restore and refresh records a deployment, and retention.finished_operation_days skips any operation with one, so nothing pruned them, their operations, their build records, or the releases they recorded. The docs said history is kept until the environment is deleted.

Deployment history is now bounded per environment by two new settings:

• retention.deployment_days (default 90) and retention.deployments_per_environment (default 50). A finished deployment is pruned only once it is past both: older than the window and beyond the environment's newest N. Either at 0 keeps everything: deployments, previews' deployments, releases and build records.
• Never pruned: the current (latest promoted) deployment, the latest one, the newest images.keep_deployments successful ones (at least one, which automatic rollback restores), any with job cleanup pending, and any that a remaining deployment's restore origin names (preview listing follows those origins back). Every deployment restore or rollback can pick is therefore kept, with its operation, target, inputs and secret pins.
• Previews keep only those deployments, of the ones that finished over an hour ago, whatever the count and day limits. The newest successful one is kept so rollback still has a target, and the hour leaves a superseded operation time to stop.
• Cascade: a pruned deployment's operation is deleted, which cascades to its attempts, inputs and secret pins. Then build and job-run rows whose operation is gone and whose output expired are deleted. Finally, releases no remaining deployment references are deleted beyond each application's newest 50.
• Batching: pruning runs in the coordinator's history pass. It selects the candidates once, then deletes them by ID 1,000 per transaction, and each delete rechecks job cleanup and restore origins accepted since. On an existing installation, the first pass after upgrading removes the whole backlog at once. That's one candidate query, then one short write per 1,000 deployments.

Surfaces: the config, its view, the NixOS module, examples/piqueld.toml, and the generated config reference and schema. The history and configuration docs no longer say history is kept until the environment is deleted. The dashboard's deployment history now ends with a one-line hint that older deployments are removed after the retention period.

No migration. The release foreign-key lookups use the deployment_release index from #398, so this should merge after it.

Proof: two new store tests build histories and check exactly which deployments survive: current, newest successful, recent, latest, the count and day windows, job cleanup, restore sources, and the preview rule with its minimum age. After pruning, the preview's origins still resolve. Removing the job-cleanup recheck, the restore-source recheck or the count limit each makes them fail. They also check that only expired builds of pruned operations go, and that only the oldest unused release beyond 50 goes. The history, preview, config, restore, rollback, release and prune tests pass (94, after the review fixes), as do tests/deployments.spec.ts in Playwright and just docs.

Overview

This change adds retention limits for deployment history. Finished deployments are pruned only when they exceed both an age limit and a per-environment count limit. Setting either limit to 0 disables the described pruning. The change includes store pruning logic, configuration fields, daemon wiring, UI text, the NixOS module, examples, documentation, and tests. It adds no migration.

The author states that this change should merge after #398, because release foreign-key lookups use the deployment_release index from that change.

Store pruning (crates/piqueld-store)

• history/mod.rs adds pub async fn prune_deployment_history(&self) -> Result<(), StoreError> on Store.
• Pruning does nothing when deployment_days or deployments_per_environment is 0.
• Otherwise, the method selects finished deployments that are older than the cutoff and beyond the per-environment limit.
• The method keeps these deployments:
  • The current and latest deployment of each environment.
  • The newest successful deployment. The source summary states "at least one newest successful deployment". The objectives state that the newest successful deployments required by images.keep_deployments are kept, so the exact count depends on that setting.
  • Deployments named as restore origins.
  • Deployments with pending job cleanup.
• Preview deployments use a separate rule. Among deployments finished more than one hour ago, only the current, latest, and newest successful deployments are kept. The newest preview deployment is also kept.
• Candidates are selected once. Deletion runs in batches of 1,000. Before each batch, the method rechecks job cleanup and restore origins.
• For each deleted deployment, the method deletes its operation. It then deletes builds whose logs have expired and whose operations no longer exist. It also deletes job-run rows whose operations no longer exist.
• The method keeps the newest 50 unused releases for each application and deletes the rest.
• lib.rs declares the history module. Store gets a history::DeploymentRetention field.
• observability/mod.rs initializes that field from the daemon configuration in Store::with_observability.
• build.rs documentation states that build records outlive their output until deployment-history pruning removes the output.
• preview/mod.rs documentation states that restore references can point to earlier deployments retained by history pruning. The source summary states that no executable behavior changes in this file.

Tests (crates/piqueld-store/src/history/tests.rs)

• The fixture sets retention to one day, three deployments per environment, and one successful deployment.
• A deployment helper creates pending, failed, and successful deployments with configurable age and promotion status.
• The first test checks that pruning keeps deployments needed for job cleanup, restore origins, the current operation, the newest successful deployment, recent deployments, and the newest three. It also checks that preview pruning removes deployments finished more than one hour ago and that preview origins still resolve.
• The second test checks that pruning removes builds for pruned deployments and expired build logs. It also checks that unused releases beyond the newest 50 are removed and releases used by deployments are kept.
• The author reports 94 passing tests for history, preview, config, restore, rollback, release, and prune. The author also reports a passing tests/deployments.spec.ts Playwright run and just docs. These results come from the PR description and were not verified in this review.

Daemon (apps/piqueld)

• reconcile/coordinator.rs: prune_history now runs deployment-history pruning on every full history pass. The pass runs independently of the operation and event retention windows. The doc comment states that zero-day windows disable pruning.

Configuration (crates/piqueld-config)

• lib.rs: RetentionConfig gains two public fields:
  • deployment_days: u64, default 90.
  • deployments_per_environment: u32, default 50.
• lib.rs documents the pruning rules. Setting either value to 0 stops the described pruning.
• lib.rs: The BuildHistoryConfig documentation says build records remain listed until deployment-history pruning removes their operation. It no longer refers to environment deletion.
• view.rs: DaemonConfig::retention_view replaces the fixed "Deployment history" value ("Until application deletion") with two values: "Deployment history (days)" and "Deployments per environment".

Browser UI (apps/piqueld-ui)

• browser/management/deployments.rs: DeploymentHistory shows a retention notice when the older-page cursor is exhausted and at least one deployment is listed. The notice states that the daemon removes older deployments beyond its history retention.

NixOS module (nix/module.nix)

• Adds services.piqueld.settings.retention.deployment_days (unsigned integer, default 90).
• Adds services.piqueld.settings.retention.deployments_per_environment (u32, default 50).
• Option descriptions state that zero disables pruning of deployment, preview, release, and build records.

Configuration schema and examples

• docs/piqueld-config.schema.json adds descriptions and fields for deployment_days and deployments_per_environment. It also updates the BuildHistoryConfig description.
• examples/piqueld.toml:
  • The [retention] table sets deployment_days = 90 and deployments_per_environment = 50, with comments.
  • The [build_history] comment states that metadata remains until its deployment is pruned.

Documentation

• docs/user/operations/history.md: Describes the 90-day and 50-per-environment limits. A deployment is removed only after it exceeds both limits. The page lists the exceptions, preview retention, build and job record removal, and release retention. It also states that setting either value to 0 keeps all deployments, releases, and build records. The statement that history lasts until environment deletion is removed.
• docs/user/reference/configuration-settings.md and docs/user/reference/configuration.md: Document the new retention settings and the updated build_history behavior.
• docs/user/reference/api.md: Build metadata is deleted after deployment-history pruning removes the operation and the output has expired.
• docs/user/applications/restore.md: Adds a troubleshooting case for a deployment that pruning removed. Previews keep only their current, latest, and newest successful deployments.
• docs/user/dashboard.md: Deployment history follows the history-and-diagnostics policy. Deployment history polling ends at the oldest deployment the daemon still retains.

Playwright screenshots

• tests/playwright/screenshots/applications.spec.ts: The deployment-restore screenshot captures the hint that ends the deployment history, instead of the second deployment card.

Walkthrough

The daemon now prunes deployment history using configurable age and per-environment count limits. The pruning pass preserves specified deployments and removes eligible operations, expired build records, and unreferenced releases. The UI and documentation describe the retention behavior.

Pruning works as designed, but analytics can undercount pruned preview deployments without flagging the result as incomplete. Several docs also promise more restorable successful preview deployments than pruning keeps. Both are small, localized fixes that can follow or ship with this change.

Full details: Title check

Explanation

The title "fix(store): bound deployment history to 90 days and 50 per environment" is a conventional commit that names the main change. The changeset adds deployment-history retention settings (deployment_days default 90, deployments_per_environment default 50) and a store-level pruning pass. The title's scope and wording match the changes. The title uses a "fix" type, which fits a bug report about unbounded history growth (STORE-04).

Full details: Description check

Explanation

The description follows the template. The title is a conventional commit. The "What and why" section explains the problem (deployment history grew without bound, and the docs said history was kept until environment deletion), describes the new settings and pruning rules, and names the tests and docs that were run. The description does not include a closing issue reference (such as "Closes #..."). It cites STORE-04 and PR #398 instead. The checklist is not ticked, and the description does not confirm that the manifest, piquelctl, and dashboard paths work. The description does say the dashboard hint was added, and it lists the config, NixOS module, and docs updates. Those items cover the checklist's documentation and NixOS module requirements, but the checklist items are not explicitly checked off.

Resolution

Optionally add a closing reference such as "Closes #..." for the tracked issue (STORE-04 may be an internal ID). Optionally tick the checklist items or state explicitly that the feature was verified through the manifest, piquelctl, and the dashboard.

Review comments at @crates/piqueld-config/src/lib.rs:
- Around line 903-905: Update the deployment-retention documentation around
images.keep_deployments to state that previews retain one successful deployment,
while other environments retain at least one even when images.keep_deployments
is 0.

Review comments at @crates/piqueld-store/src/history/mod.rs:
- Line 92: Update the deployment-pruning batch in the history store so each
deletion advances history_coverage.pruned_through_ms in the same transaction,
using the greatest finished_at_ms among deployments deleted in that batch and
preserving any larger existing value. Leave pruned_through_id unchanged so
event-stream HistoryExpired behavior is preserved.

Review comments at @docs/user/applications/restore.md:
- Around line 204-206: Update the preview restore description to state the
normal pruning rule without claiming that only the newest successful deployment
can be restored; link to the documented retention exceptions, including the
one-hour window and the effect of setting either retention limit to zero.

Review comments at @docs/user/reference/configuration-settings.md:
- Line 418: Update the deployment-retention description to state that previews
keep their current deployment, latest deployment, and newest successful
deployment among those finished over an hour ago. Preserve the surrounding
retention rules and clarify that previews keep only these qualifying
deployments.
