Summary

  • add paginated AWS Backup vault discovery and a read-only recovery posture detail view
  • show recovery points, lifecycle timing, protected resources, recent failed jobs, vault lock state, and per-section partial-result warnings
  • integrate filtering, saved views, context/region resets, help, tests, the AWS SDK dependency, and user-facing documentation

README's duplicated global-filter paragraph is intentionally unchanged because #318 owns that exact cleanup. After #318 lands, this branch should be rebased while retaining AWS Backup in the single remaining inventory.

Related Issues

Closes #321

This PR successfully implements a read-only AWS Backup browser with excellent code quality and comprehensive testing. The implementation demonstrates strong adherence to existing patterns in the codebase.

Key Strengths:

  • Well-structured paginated API calls with graceful partial failure handling
  • Proper context cancellation checks to prevent resource leaks
  • Comprehensive unit tests covering edge cases (pagination failures, stale loads, overlay navigation)
  • Clean integration with existing TUI patterns (filtering, context switching, help system)
  • Terminal control character escaping for security
  • Thoughtful UX details (warning summaries, stale detail detection, scroll state management)

Technical Highlights:

  • Pagination correctly preserves completed pages when later pages fail
  • Independent section loading in vault details allows partial success with warnings
  • Sort implementations prioritize failed/attention-needed items for operator visibility
  • Repository interface properly extends with BackupClientAPI

The code is production-ready with no blocking issues identified. The feature integrates seamlessly with the existing architecture and provides valuable AWS Backup visibility for operators.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to b05ac

The new Backup browser can display stale results after a context reset, retain an outdated filter in an unfiltered saved view, hide detail content when warnings are present, misalign wide Unicode vault names, and vary ordering for equal records. The PR should not merge without addressing or explicitly accepting these current-head correctness and usability risks.

Explanation

The implementation satisfies issue #321: it adds AWS Backup models and repository methods, paginated vault and detail views, partial-result warnings, deterministic sorting, tests, read-only behavior, and documentation. The requested docs/service-specific-highlights.md file does not exist, and equivalent coverage is documented in the updated README and architecture and project-overview pages.

Full details: Out of Scope Changes check

Explanation

The changes remain within the AWS Backup browser scope. They add read-only discovery, filtering, context handling, tests, dependency integration, and related documentation. No backup, restore, delete, or vault-lock mutations are introduced. The unchanged README paragraph is explicitly reserved for issue #318.

same warning-aware visibleLines calculation, accounting for the two lines
consumed when detailErrors are present so maxOffset matches the rendered detail
window. Add a paging test with detailErrors populated that verifies the final
warning-adjusted lines are reachable.
- Around line 80-108: Introduce a monotonically increasing Backup load
generation, increment it when Backup state is reset or a new load begins, and
capture it in both vault-list and vault-detail commands. Add the generation to
backupVaultsLoadedMsg and backupVaultDetailLoadedMsg, then have the handlers
reject messages whose generation differs from the active Backup generation
before mutating state. Add a regression test covering a prior-context completion

clears the prior filterBackupVaults value. Add a regression test covering
opening an unfiltered Backup saved view after a filtered session.

- Around line 31-37: Replace the fmt.Sprintf-based formatting in
BackupVault.DisplayTitle with the shared Lipgloss table renderer, or move this

style, preserving the existing vault fields and lock display.

In `@internal/services/aws/backup.go`:
- Around line 156-172: The detail sort functions sortBackupProtectedResources,
sortBackupJobs, and sortBackupRecoveryPoints need deterministic final
tie-breakers. Preserve their existing primary comparisons, then compare
normalized ARN for resources and recovery points, and ID for jobs when all
current sort keys are equal.

Reviewed head: db8c258

Findings

  1. P2 — One-sided Vault Lock bounds render as a false N-0 days range (internal/services/aws/backup.go:186-187, internal/app/screen_backup.go:438-440)

    MinRetentionDays and MaxRetentionDays are optional AWS fields, but mapping them through aws.ToInt64 discards whether each bound was absent. backupLockSummary then formats both values whenever either is non-zero. A common lock with only a 7-day minimum therefore appears as locked (7-0 days), incorrectly telling operators that the maximum is zero days.

    Preserve presence for each retention bound (pointers or explicit known flags) and render the minimum and maximum independently; add coverage for minimum-only, maximum-only, and unbounded lock configurations.

  2. P2 — Missing recovery-point sizes are displayed as real zero-byte backups (internal/services/aws/backup.go:207, internal/app/screen_backup.go:379)

    BackupSizeInBytes is optional, but aws.ToInt64(nil) collapses “not reported” to 0, and the detail view renders that as 0 B. For resource types or responses where AWS omits the field, the recovery browser therefore presents unknown size as an actual empty backup, which can mislead recovery-readiness triage.

    Preserve whether the SDK field was present and render -/unknown when absent while retaining 0 B for an explicitly reported zero; add a mapping/rendering test that distinguishes nil from zero.

- render one-sided Vault Lock retention bounds accurately

- distinguish unknown recovery-point sizes from explicit zero values

Applied the YoungJinJung review findings in commit 9312bb2. Preserved Vault Lock retention-bound presence for minimum-only, maximum-only, and unbounded policies; preserved recovery-point size presence so omitted values render as a dash while explicit zero remains 0 B; and added mapping/rendering regression coverage. Local validation passed: targeted Backup tests, make test, make build, and git diff --check.

Addressed the current review findings in b760dc4. Detail scrolling now uses one warning-aware window calculation; unfiltered saved views clear prior feature filters; Backup vault rows use Lipgloss display-width columns; detail sorts have unique final keys; and stale same-name prior-context results are covered through the existing shared generation guard. Validation passed: targeted tests, make test, make build, go vet ./..., focused race tests, and git diff --check. The issue checklist reference to docs/service-specific-highlights.md cannot be updated because that file does not exist on current main; the feature coverage is already documented in README.md and both project overview and architecture documents.

Reviewed head: b760dc4

Findings

  1. P2 — Detail refresh leaves vault-level recovery posture stale (internal/app/screen_backup.go:232-235, internal/services/aws/backup.go:56-57)

    Pressing r says it is refreshing the selected vault, but loadDetail passes the original list-row snapshot into GetBackupVaultDetail, which copies that BackupVault and only reloads recovery points, protected resources, and jobs. Vault state, recovery-point count, encryption metadata, and especially Vault Lock/retention settings can therefore remain stale indefinitely even while the refreshed screen looks current, which can mislead recovery-readiness checks.

    Re-fetch the selected vault metadata as part of the detail refresh (for example, reuse the existing vault-list call and match by ARN/name, or add DescribeBackupVault and document its permission), then add a refresh regression that changes lock/count metadata between the initial list and refreshed detail.

Reviewed current head b760dc4. The optional metadata fixes, warning-aware scrolling, saved-view filter reset, Unicode column layout, deterministic tie-breakers, and shared generation guard all hold in the complete diff; all current inline threads are resolved and I found no new actionable code issue. Local make test, make build, focused Backup race tests, and git diff --check pass. Do not merge yet: #318 must land first, then rebase and add AWS Backup to the single retained filtering inventory; the current head also still needs an Amazon Q result and an independent approval satisfying branch protection.

- reload selected vault metadata before refreshing recovery detail
- cover changed recovery-point counts and Vault Lock posture

Applied the current-head vault-refresh finding in cfc31b7. Explicit detail refreshes now re-list and re-identify the selected vault before loading recovery points, protected resources, and jobs, so recovery-point count, encryption, and Vault Lock metadata are current without adding a new AWS permission. The refreshed vault also replaces the selected detail snapshot, and a missing vault fails instead of presenting stale posture. Added a regression that changes recovery-point count and Vault Lock retention between the initial list and refresh. Validation passed: focused Backup tests, make test, make build, focused Backup race tests, and git diff --check.

Review Summary

This PR successfully implements a read-only AWS Backup vault browser with excellent code quality. The implementation follows AWS SDK best practices and integrates cleanly with the existing application architecture.

Strengths

Robust Error Handling

  • Partial pagination results are preserved when later pages fail
  • Independent detail sections continue working when others are denied
  • Clear error propagation with contextual wrapping

Security & Reliability

  • Context cancellation is properly checked (ctx.Err())
  • Nil pointer checks prevent panics
  • Proper use of optional value tracking (e.g., MinRetentionKnown, SizeBytesKnown)

Code Quality

  • Clean separation of concerns (AWS SDK layer, models, UI)
  • Comprehensive test coverage including edge cases
  • Consistent sorting with stable tie-breakers
  • Well-documented public APIs
  • Proper interface definitions for testability

User Experience

  • Graceful degradation with inline warnings for partial data
  • Filtering, keyboard navigation, and scrolling support
  • Terminal control sequence escaping ensures safe rendering

Findings

  1. P2 — A detail refresh is discarded after returning to the vault list (internal/app/screen_backup.go:104-108)

    The detail completion replaces only selected and detail; vaults and filtered still contain the pre-refresh BackupVault. After r observes a changed recovery-point count or Vault Lock policy, pressing Esc therefore renders the old row, and pressing Enter again selects that stale row and calls loadDetail(..., false), copying the old vault metadata back into the detail screen. Reconcile msg.detail.Vault into the canonical vault slice and reapply the active filter/index before setting the selection (the existing DynamoDB reconcileTable flow is a useful pattern). Add a regression covering refresh → Esc → Enter so refreshed metadata remains current.

  2. P2 — An incomplete paginated refresh is reported as vault deletion (internal/app/screen_backup.go:274-281)

    ListBackupVaults intentionally returns completed pages plus listWarnings and a nil fatal error when a later page fails. If the selected vault was on that unavailable later page, findBackupVault returns false and this branch raises “is no longer available,” discards the pagination warning, and routes the user to the fatal error screen even though the refresh never established that the vault was deleted. When the list is partial, preserve the prior vault metadata and surface the warning (or otherwise report the pagination failure without claiming deletion); reserve the unavailable error for a complete list. Add a refresh test where an earlier page succeeds and the selected vault’s page fails.

Finding

  1. P2 — A partial refresh can falsely report the selected vault as deleted (internal/app/screen_backup.go:273-282)

    ListBackupVaults deliberately returns completed pages with listWarnings when a later page fails. If the selected vault was on that failed page, findBackupVault cannot find it and this path returns backup vault … is no longer available, replacing the usable detail with a fatal error. That contradicts the PR’s partial-result behavior and turns a transient pagination denial into false deletion posture.

    Only conclude that the vault disappeared when the re-list completed without warnings. When the list is partial and the vault is absent, retain the existing vault snapshot, continue loading its detail, and surface the list warning. Add a refresh regression with one completed page followed by an error where the selected vault is not in the retained page.

- reconcile refreshed vault metadata into the list state\n- keep prior vault details when a paginated refresh is incomplete

Applied the current-head review findings in b05acf4. Refreshed vault metadata is now reconciled into the canonical and filtered list state, so refresh → back → reopen keeps the new recovery count and Vault Lock posture. If a later vault-list page fails and the selected vault is absent from the retained pages, refresh now preserves the prior vault snapshot, continues loading detail, and surfaces the pagination warning instead of claiming deletion. Added regressions for both flows. Validation passed: focused Backup refresh tests, focused race tests, make test, make build, and git diff --check.

The AWS Backup recovery browser implementation is well-designed and follows established patterns in the codebase. The code includes proper error handling, pagination support, partial result recovery, context cancellation checks, and comprehensive test coverage. No critical defects found that would block merge.

Implementation Highlights:

  • Robust paginated API calls with partial result recovery when later pages fail
  • Independent error handling for detail sections (recovery points, protected resources, failed jobs)
  • Proper context cancellation checks to prevent stale data rendering
  • Consistent sorting and filtering patterns matching other service implementations
  • Comprehensive test coverage for core functionality

The feature is production-ready and integrates well with the existing architecture.

Findings

  1. P2 — Subsequent detail failures are hidden while affected sections render as empty (internal/app/screen_backup.go:403-405)

    The repository deliberately returns one warning for each independently loaded section, but this view passes only bm.detailErrors[0] to renderWarningSummary. When two sections fail—or when a refresh pagination warning precedes a section failure—the remaining failures are not identified anywhere, while those sections still render None available or None in the AWS Backup 30-day job window. That makes unavailable recovery-posture data look like a confirmed empty result.

    Render every detail warning, or retain per-section availability and render an explicit unavailable state in the affected section. Make detailVisibleLines account for the resulting warning height, and add a view test with two distinct section errors that verifies both are visible and the final detail lines remain reachable.

Finding

  1. P2 — Preserve why a completed job needs attention (internal/services/aws/backup.go:142-145, 250-259; internal/app/screen_backup.go:544-557)

    backupJobNeedsAttention includes a COMPLETED job when MessageCategory is non-empty and not SUCCESS, but mapBackupJob drops MessageCategory and the detail view renders only the state. If AWS omits StatusMessage, the job therefore appears under “Recent Failed / Expired Jobs” simply as COMPLETED, so the operator cannot tell why an apparently successful job was flagged; this also does not substantiate the README promise to show completed-with-issues jobs.

    Carry MessageCategory (or a derived completed-with-issues display status) into BackupJob and render it, then add a regression for COMPLETED plus a non-SUCCESS category that verifies the issue is visible while a SUCCESS job remains excluded.

Validation on this head: make test, make build, focused Backup race tests, and git diff --check all pass.

Applied both current-head review findings in b9d6c63. The detail view now renders every lookup warning and subtracts each rendered warning line from the scroll window. Backup jobs now retain and render MessageCategory, so completed-with-issues jobs explain why they need attention while SUCCESS jobs remain excluded. Validation passed: focused Backup tests, make test, make build, focused Backup race tests, and git diff --check.

Review Summary

This PR adds AWS Backup vault browsing functionality with comprehensive pagination handling, partial result recovery, and user-facing views. The implementation is well-tested and follows the existing patterns in the codebase.

Critical Issues Found (2)

Two logic errors require fixes before merge:

  1. Context cancellation handling - The cancellation check in GetBackupVaultDetail occurs only after all three API sections complete. This prevents fast-fail behavior when contexts are cancelled, wasting resources.

  2. Variable shadowing - In reconcileVault, the inner loop variable shadows the outer loop variable, potentially causing incorrect index updates when matching vaults are found.

Both issues have been commented with specific fixes.

Addressed the valid Amazon Q cancellation finding in 575f15a: detail loading now stops between independent AWS sections when the context is canceled, with a regression proving later section calls are skipped. The reconcileVault shadowing claim is a false positive: the inner index intentionally selects the matching row in bm.filtered after the canonical bm.vaults update, and the outer index is no longer used. Validation passed again: focused Backup tests, make test, make build, focused Backup race tests, and git diff --check.

Reviewed current head 575f15acf7a57286bcc9cac856e1400458a4b332. The multi-warning rendering, completed-with-issues job context, and between-section cancellation fixes resolve the latest findings; I read the complete diff, tests, CI, prior reviews, inline threads, and new commits and found no new actionable code issue. Local make test, make build, go vet ./..., go test -race ./internal/services/aws ./internal/app -run Backup -count=1, and git diff --check origin/main...HEAD pass. Do not merge yet: #318 must land first, then rebase this branch and add AWS Backup only to the single retained filtering inventory; an independent approval satisfying branch protection is still required.

Findings

  1. P2 — Preserve Backup load completions while Add Context is open (internal/app/screen_backup.go:57-70)

    finishBackupLoad relies on backupOverlayPrevious to replace the screenLoading return target when a result arrives behind an overlay, but this switch does not handle screenContextAdd. A user can start a Backup load, press C, enter Add Context with a, and receive the Backup result while that screen is active. The handler consumes the result but leaves ctxPrevScreen == screenLoading; after exiting Add Context and then the context picker, normal back-navigation lands on an orphaned loading screen with no command left to complete it.

    Include screenContextAdd in the Backup overlay chain (following ctxPrevScreen, as the context-picker flow ultimately does), or preserve that pending context return explicitly. Add a regression that delivers a vault or error completion while screenContextAdd is active and verifies that exiting the context flow returns to the completed Backup target instead of screenLoading.

- route Add Context through the existing Backup overlay chain
- cover returning from context creation to a completed vault load

Applied the current-head Add Context finding in 7c27e38. Backup success and error completions now traverse screenContextAdd through the existing context return chain, so closing Add Context and the context picker returns to the completed Backup target instead of an orphaned loading screen. Added an end-to-end regression for vault completion through that exit flow. Validation passed: focused Backup navigation tests, make test, make build, gofmt -d, and git diff --check.

This AWS Backup browser feature is well-implemented with strong attention to error handling and resilience. The code demonstrates several notable strengths:

Architecture & Error Handling
The implementation follows a robust partial-result pattern that keeps completed pages available when pagination fails, preventing data loss during API errors. Context cancellation is properly handled between independent data sections, ensuring graceful termination.

Code Quality
The codebase maintains consistency with existing patterns throughout the repository. Comprehensive test coverage validates pagination behavior, partial result handling, context cancellation, and edge cases. The interface-based design with BackupClientAPI enables effective mocking and testing.

Documentation & Integration
Documentation is thorough with clear inline comments explaining complex behaviors. The feature integrates seamlessly with existing UI patterns for filtering, navigation, and error display.

The implementation is production-ready and follows AWS SDK best practices. No blocking issues were identified.

Re-reviewed current head 7c27e38e484e44f0c86a9906870085989816c7ce. The Add Context overlay traversal now preserves Backup success/error completions behind screenContextAdd, and the regression covers returning through the context picker to the completed vault list. I read the complete diff, tests, CI, prior reviews, inline threads, and the new commit and found no new actionable code issue. Local make test, make build, go vet ./..., go test -race ./internal/services/aws ./internal/app -run Backup -count=1, and git diff --check origin/main...HEAD pass. I did not approve or merge: #318 still owns the prerequisite README deduplication/rebase, and branch protection requires an independent approval that this PR author identity cannot provide.

Independent review at head 7c27e38: no new actionable code findings. Full test suite, go vet, build, Backup-focused race tests, diff, CI, and prior threads were checked. Approval is deferred because #318 must land first and this branch must reconcile the single README filtering inventory; please request re-review on the rebased head.
