Implementation Spec for Issue #4

Objective

Replace all native browser confirm() dialogs in the admin page (and throughout the dashboard) with custom Bootstrap HTML modals that match the existing UI design language.

Background

Tested the admin page via browser MCP. The current state:

• Admin page (http://127.0.0.1:9999 → Admin tab) shows 5 action buttons: Shutdown, Stop All, Reset All, Clean Jobs, Populate Demo Data
• 4 of 5 admin actions use native window.confirm() which shows a plain OS dialog box
• Additionally, 7 other places throughout dashboard.js use confirm(): deleteAction, deleteJob, killAllJobsInRun, deleteRun, deleteService, deleteSecret, killService
• The codebase already has a custom modal pattern used for job/run details (.job-modal-overlay / .job-modal classes with fade-in animation)

Requirements

• Replace every confirm() call with a reusable Bootstrap-styled confirmation modal
• Modal must support: title, message body, confirm button label + color (danger/warning/primary), cancel button
• Destructive actions (Shutdown, Reset All, Stop All, Delete) get a red danger-styled confirm button
• Non-destructive actions (Clean Jobs, Populate Demo Data) get a warning/primary styled button
• Keyboard Escape closes the modal (cancel)
• Click outside the modal closes it (cancel)
• Modal must be async-friendly (await the user's choice)

Files to Modify

• crates/hero_proc_ui/static/js/dashboard.js — add showConfirmModal() helper; replace all confirm() calls
• crates/hero_proc_ui/static/css/dashboard.css — add CSS for the confirmation modal

Implementation Plan

Step 1: Add CSS for confirmation modal

Files: crates/hero_proc_ui/static/css/dashboard.css

• Add .confirm-modal-overlay (fixed fullscreen backdrop, z-index 9999, fade-in)
• Add .confirm-modal (centered card, max-width 480px, dark-themed matching existing modals)
• Add .confirm-modal-header, .confirm-modal-body, .confirm-modal-footer
• Add button styles: .confirm-btn-danger, .confirm-btn-warning, .confirm-btn-cancel
• Match existing .job-modal animation pattern (slide-up + fade-in)
  Dependencies: none

Step 2: Add showConfirmModal() helper to dashboard.js

Files: crates/hero_proc_ui/static/js/dashboard.js

• Add function showConfirmModal(title, message, {confirmText='Confirm', confirmClass='confirm-btn-danger', icon='bi-exclamation-triangle'} = {}) that returns a Promise<boolean>
• Creates overlay + modal DOM dynamically (same pattern as showJobModal)
• Resolves true on confirm click, false on cancel/escape/click-outside
• Auto-removes from DOM after resolution
  Dependencies: Step 1

Step 3: Replace confirm() calls in admin functions (lines 2484, 2493, 2502, 2512)

Files: crates/hero_proc_ui/static/js/dashboard.js

• shutdownHeroProc(): replace confirm() with await showConfirmModal('Shutdown Server', '...', {confirmText:'Shutdown', confirmClass:'confirm-btn-danger', icon:'bi-power'})
• stopAllServices(): replace with await showConfirmModal('Stop All Services', '...', {confirmText:'Stop All', confirmClass:'confirm-btn-danger', icon:'bi-stop-circle'})
• cleanOldJobs(): replace with await showConfirmModal('Clean Old Jobs', '...', {confirmText:'Clean Jobs', confirmClass:'confirm-btn-warning', icon:'bi-trash3'})
• resetAllServices(): replace with await showConfirmModal('Reset All Services', '...', {confirmText:'Reset All', confirmClass:'confirm-btn-danger', icon:'bi-arrow-counterclockwise'})
  Dependencies: Step 2

Step 4: Replace confirm() calls in all other dashboard functions

Files: crates/hero_proc_ui/static/js/dashboard.js

• deleteAction(name) line 661: replace with showConfirmModal
• deleteJob(id) line 852: replace with showConfirmModal
• killAllJobsInRun(runId) line 910: replace with showConfirmModal
• deleteRun(id) line 1316: replace with showConfirmModal
• deleteService(name) line 1535: replace with showConfirmModal
• deleteSecret(key) line 1673: replace with showConfirmModal
• killService(name) line 1711: replace with showConfirmModal
• Inline confirm in job modal (line 2030): replace inline confirm with showConfirmModal pattern
  Dependencies: Step 2

Acceptance Criteria

• No confirm( calls remain anywhere in dashboard.js
• All 5 admin page actions trigger the new Bootstrap modal when clicked
• All other delete/kill actions throughout the dashboard use the same modal
• Modal appearance matches the dark theme of the existing UI
• Escape key and click-outside both cancel the action
• Confirm button color matches action severity (red for destructive, yellow/orange for maintenance)
• Animations match existing modal pattern (fade-in, slide-up)

Notes

• The existing showJobModal / showRunModal pattern in dashboard.js is the reference implementation to follow
• All admin functions are already async, so await showConfirmModal(...) works without refactoring
• The inline onclick confirm on line 2030 (inside job modal HTML string) needs special handling — refactor to a named function
• Bootstrap 5 is already available in the project (used in base.html)
• Step 3 and Step 4 can run in parallel since they touch different function ranges in dashboard.js (Step 3: lines 2483–2523, Step 4: lines 661–1711)

Bug fix committed: 0940941

Browse: 0940941

Root cause: cleanup_leftover_socket_processes() in reset_all_services was passed state.socket_path (the hero_proc server socket path) as the socket to skip. This meant hero_proc_ui.sock was not excluded from cleanup — the function would find the UI process listening on it, send SIGTERM, wait 500ms, then SIGKILL it, severing the HTTP connection before any response was returned.

Fix: Added ui_socket_path field to AppState, populated from args.socket in main.rs. Pass state.ui_socket_path to cleanup_leftover_socket_processes so the UI socket is correctly excluded.

Verified: Reset All now stops + deletes 11 services and returns a proper JSON response with the UI still running.

Implementation Complete — Issue #4: Custom Confirm Modals + Full DB Reset

Summary of Changes

1. Custom Bootstrap Confirm Modals (replaces all native confirm() calls)

• static/css/dashboard.css — Added modal overlay CSS with fade/slide animations, danger/warning/primary button styles
• static/js/dashboard.js — Added showConfirmModal(title, message, opts) async helper (promise-based); replaced all 11 confirm() call sites across the dashboard (shutdown, stop-all, reset-all, clean-jobs, delete service/action/secret/job/run, kill-service, kill-all-jobs-in-run)

2. Reset-All Wipes Full Database

• src/routes.rs — Extended reset_all_services handler with 5 new phases:
  • Phase 4: Delete all actions via client.action_list() → client.action_delete()
  • Phase 5: Delete all secrets via client.secret_list() → client.secret_delete()
  • Phase 6: Delete all runs via client.run_list() → client.run_delete()
  • Phase 7: Purge all jobs via client.job_purge(older_than_ms: 0)
  • Phase 8: Cleanup leftover socket processes (skip UI socket)

3. Fix: Reset-All Self-Kill Bug

• src/main.rs — Added ui_socket_path to AppState so the cleanup phase correctly skips the UI's own socket
• Without this fix, reset-all would kill the UI process mid-request

4. Fix: OpenRPC Spec + SDK for action.list and secret.list

• openrpc.json — Changed action.list and secret.list result schemas from bare arrays to wrapped objects ({"specs": [...]} and {"secrets": [...]})
• src/rpc/action.rs and src/rpc/secret.rs — Updated handlers to wrap responses
• hero_proc_lib/src/db/rpc.rs — Updated lib dispatch handlers to match
• This fixes the generated SDK's #[serde(flatten)] Vec<T> deserialization bug — ActionListOutput.specs and SecretListOutput.secrets now work correctly
• Updated all tests (db/rpc.rs, integration.rs) to use typed SDK calls instead of call_raw workarounds

Test Results (Browser MCP)

All 5 admin actions tested end-to-end:

Action	Result
Shutdown confirmation modal	✅ Custom modal shown, cancel works
Stop All confirmation modal	✅ Custom modal shown
Reset All (full DB wipe)	✅ Deleted 25 actions, 12 secrets, 21 runs, 6 jobs — all counters → 0
Clean Jobs confirmation modal	✅ Custom modal shown
Populate Demo Data	✅ Creates demo actions/services/secrets

Unit/lib tests: 214 passed, 0 failed
Reset-All API response: {"actions_deleted":25,"secrets_deleted":12,"runs_deleted":21,"jobs_purged":6,"errors":[]}
Post-reset verification: Actions=0, Secrets=0, Runs=0, Jobs=0 ✓

Root Cause Fix: hero_rpc macro bug

While implementing the full DB reset, we traced the action.list / secret.list deserialization failures to a bug in the openrpc_client! macro in hero_rpc.

The bug

For method result schemas that are bare arrays (not wrapped in an object), the macro generated:

pub struct ItemListOutput {
    #[serde(flatten)]   // ← wrong: flatten cannot handle sequences
    pub value: Vec<Item>,
}

#[serde(flatten)] is a serde feature for merging object/map fields — it has no defined behavior for sequences and silently fails to deserialize a JSON array [...].

The fix

#[serde(transparent)] is the correct attribute. It serializes/deserializes the struct as its single inner field, working correctly for arrays, strings, numbers, and any other type.

#[serde(transparent)]  // ← correct: works for all types
pub struct ItemListOutput {
    pub value: Vec<Item>,
}

Fixed in hero_rpc commit 9e96dd1 with a regression test.

What we kept in hero_proc

Even with the macro fixed, action.list and secret.list now return wrapped objects ({"specs": [...]}, {"secrets": [...]}) rather than bare arrays — this is better API design regardless, as it allows adding fields later without a breaking change and is consistent with service.list.

## Root Cause Fix: `hero_rpc` macro bug While implementing the full DB reset, we traced the `action.list` / `secret.list` deserialization failures to a bug in the `openrpc_client!` macro in [hero_rpc](https://forge.ourworld.tf/lhumina_code/hero_rpc). ### The bug For method result schemas that are bare arrays (not wrapped in an object), the macro generated: ```rust pub struct ItemListOutput { #[serde(flatten)] // ← wrong: flatten cannot handle sequences pub value: Vec<Item>, } ``` `#[serde(flatten)]` is a serde feature for merging object/map fields — it has no defined behavior for sequences and silently fails to deserialize a JSON array `[...]`. ### The fix `#[serde(transparent)]` is the correct attribute.
