Project-SDE-WP-Suite/html/help.js

/* Shared Help center + tooltip module for the Work Package Suite.
   Included by the home page, the SOP wizard and the work package creator. It injects:
     - tooltip styles for the .help-tip (ⓘ) component and [data-tip] hovers
     - a searchable, multi-topic Help center modal opened via window.openHelp()
     - a floating "?" launcher on any page that doesn't already have a Help button

   API (unchanged + extended):
     openHelp()            open the help center
     openHelp('topicId')   open and jump to a topic (e.g. openHelp('constraints'))
     closeHelp()           close it
   Add a Help button anywhere with onclick="openHelp()". */

      <h3>Getting started</h3>
      <p>The Work Package Suite turns a project's standard procedure into release-ready <strong>Installation Work Packages (IWPs)</strong>. You work in three stages, always in the same order:</p>
      <ol>
        <li><strong>Pick or create a Project</strong> on the home page. Each project keeps its own SOP and its own Work Packages, so you can run many jobs at once.</li>
        <li><strong>SOP Configuration</strong> — set the project baseline in 10 steps (team, sign-offs, WP types, governance &amp; sizing, quality, platforms, sequence, constraints, sources). Every Work Package inherits these defaults. The Creator stays locked until the SOP is marked complete.</li>
        <li><strong>Work Package Creation</strong> — author individual IWPs against the SOP, clear their constraints, and issue them to the field.</li>
        <li><strong>Dashboard</strong> — track status, hours, due dates, and what's gating each package across the project.</li>
      </ol>
      <h4>Moving around</h4>
      <p>From the home page, open <strong>SOP Configuration</strong>, the <strong>Work Package Creator</strong>, or the <strong>Dashboard</strong>. Inside the suite, switch any time using the top tabs: <strong>⚙️ SOP Configuration</strong>, <strong>📋 Work Package Creation</strong>, and <strong>📊 Dashboard</strong>. The active project and SOP follow you across all of them.</p>
      <h4>Quick start</h4>
      <ol>
        <li><strong>Open “SOP Configuration”</strong> and complete the 10 steps for your project (~15 minutes).</li>
        <li><strong>Finish the SOP</strong> — its home-page card turns green and unlocks the Work Package Creator.</li>
        <li><strong>Open “Work Package Creation”</strong> to author packages with your SOP defaults pre-populated.</li>
        <li><strong>Update from the field</strong> using the <strong>Field View</strong>, and <strong>leave feedback</strong> on any page with the Feedback button.</li>
      </ol>
      <div class="ui-help-callout">New here? On the home page choose the <strong>Sample Project</strong>, then click <strong>⭐ Load sample</strong> in the suite to see a fully filled-out SOP and an example Work Package.</div>` },

    { id: 'projects', title: 'Projects', body: `
      <h3>Projects</h3>
      <p>A <strong>project</strong> is the top-level container — every SOP and Work Package belongs to one. Create or select projects on the home page.</p>
      <h4>Project fields</h4>
      <ul>
        <li><strong>Project Name</strong> (required)</li>
        <li><strong>Project Number</strong></li>
        <li><strong>Client</strong></li>
        <li><strong>Division / Sector</strong></li>
        <li><strong>Site / Location</strong></li>
      </ul>
      <h4>The active project</h4>
      <p>The <strong>active project</strong> is the one you're currently working in. All SOP and Work Package data is scoped (namespaced) to it, so switching projects loads that project's own configuration and packages — nothing leaks between jobs. Use the <em>change</em> link next to the active project name to switch.</p>
      <div class="ui-help-callout">Projects are stored centrally via the API and mirrored to your browser, so the suite still works offline; it re-syncs when the connection returns.</div>` },

    { id: 'sop', title: 'SOP Configuration', body: `
      <h3>SOP Configuration (10 steps)</h3>
      <p>The SOP is the project baseline. Walk the 10 steps with <strong>← Back</strong> / <strong>Next →</strong>, or jump using the step indicators. The final step is <strong>✓ SOP complete</strong> — saving it unlocks the Work Package Creator and turns the home-page card green.</p>
      <ol>
        <li><strong>Project Basics</strong> — name, number, client, division/sector, site. Inherited by every WP.</li>
        <li><strong>Project Team Leadership</strong> — PM, APM, CM, QM, plus any additional members (<em>+ Add Team Member</em>).</li>
        <li><strong>Required Sign-Off Roles</strong> — Superintendent and Foreman are always required; add optional roles (HSE, Quality Rep, Planner, etc.) with <em>+ Add Role</em>.</li>
        <li><strong>Work Package Types</strong> — enable the install types this project uses (Conduit Install, Wire Pull, Terminations, …). Enabled types populate the WP type picker.</li>
        <li><strong>Governance &amp; WP Numbering</strong> — the WP <strong>number format</strong> (e.g. <code>WP##-[Sector]-[TYPE]</code>), issuance strategy, the project's <strong>disciplines</strong>, the <strong>discipline strategy</strong>, and <strong>WP sizing</strong> (see <a data-help-jump="sizing">Sizing</a> and <a data-help-jump="disciplines">Disciplines</a>).</li>
        <li><strong>Quality &amp; Inspection Strategy</strong> — QC requirement, photo/documentation standard, and hold/witness points.</li>
        <li><strong>Tracking &amp; Commissioning Platforms</strong> — e.g. CxAlloy, Procore, ACC.</li>
        <li><strong>Construction Sequence</strong> — the install flow; reorder by dragging (⠿), edit labels, add <em>◆ QC Hold</em> gates or custom steps. These feed the WP "predecessor" picker.</li>
        <li><strong>Release Gate Constraints</strong> — choose which standard AWP constraints apply and add custom ones (see <a data-help-jump="constraints">Constraints</a>).</li>
        <li><strong>Engineering Sources &amp; References</strong> — labelled links (Design Drawings, Specs, …) that appear as quick-access buttons in the WP Creator's <em>Drawings &amp; Attachments</em>.</li>
      </ol>
      <div class="ui-help-callout">Fields a WP inherits from the SOP show a <strong>"from SOP"</strong> tag and are locked. You can override a locked field with <strong>🔒 Edit</strong>, which requires a logged reason.</div>` },

    { id: 'wps', title: 'Work Packages', body: `
      <h3>Creating Work Packages</h3>
      <p>In the Creator, start a package with <strong>+ New</strong> (blank, auto-numbered) or <strong>⧉ Duplicate</strong> (copies a saved package and increments the number). The <strong>WP Number</strong> is built automatically from the SOP number format plus your scope fields, the WP type, and a counter — it's read-only.</p>
      <h4>Key fields</h4>
      <ul>
        <li><strong>Subject / Title</strong> (required) and <strong>WP Type</strong> (required, from the SOP).</li>
        <li><strong>Assets</strong> — link each controls.dev asset the package covers.</li>
        <li><strong>Disciplines</strong> — which trades the package covers (see <a data-help-jump="disciplines">Disciplines &amp; Split</a>).</li>
        <li><strong>Scope &amp; Work</strong> — the sequenced steps the crew performs (per-discipline in multi-discipline mode).</li>
        <li><strong>Labor – Est. Hrs.</strong> — drives the sizing check (see <a data-help-jump="sizing">Sizing</a>).</li>
        <li><strong>Material List</strong> — the bill of materials; import from CSV/Excel or add lines manually.</li>
        <li><strong>Drawings &amp; Attachments</strong> — documents and SOP source-folder links.</li>
        <li><strong>Kitting &amp; Material Movement (MIMO)</strong> — kitting status, warehouse owner, move date/location.</li>
        <li><strong>Constraints</strong> — the release gate (see <a data-help-jump="constraints">Constraints</a>).</li>
        <li><strong>Quality / Hold Points</strong>, <strong>Approvals &amp; Sign-offs</strong>, and <strong>Closeout</strong> (actual hours, as-builts, lessons learned — shown at QC/Closed).</li>
      </ul>
      <h4>Saving</h4>
      <p><strong>Save Draft</strong> stores the package; <strong>⚡ Save &amp; View</strong> saves and renders the print-ready output. Drafts auto-save to your browser as you type, so nothing is lost if you close the tab.</p>` },

      <p>On a multi-discipline package, each discipline carries its own status and the overall status <strong>rolls up to the least-advanced discipline</strong> — so a package is never "Closed" while one trade still lags.</p>` },

    { id: 'constraints', title: 'Constraints & release', body: `
      <h3>Constraints &amp; release readiness</h3>
      <p>Constraints are the readiness checklist that gates a package's release to the field. They follow Advanced Work Packaging (AWP Vol II §2.3.2). The standard set:</p>
      <ol>
        <li>Safety &amp; Permitting</li><li>Quality Control / Inspection</li><li>IFC Drawings &amp; Specs</li>
        <li>Schedule</li><li>Materials (on site, bagged &amp; tagged)</li><li>Prefabrication</li>
        <li>Work Access &amp; Laydown</li><li>Craft Availability</li><li>Construction Equipment &amp; Tools</li>
        <li>Scaffolding / Access Equipment</li>
      </ol>
      <p>Pick which apply (and add custom ones) in <strong>SOP Step 9</strong>. Each constraint on a package has one of three states:</p>
      <table>
        <tr><th>State</th><th>Effect</th></tr>
        <tr><td><strong>Open</strong></td><td>Not yet cleared — <em>blocks release</em>.</td></tr>
        <tr><td><strong>Cleared</strong></td><td>Requirement met — counts toward release-ready.</td></tr>
        <tr><td><strong>N/A</strong></td><td>Not applicable to this package — counts as cleared.</td></tr>
      </table>
      <h4>The release gate</h4>
      <ul>
        <li>A package is <strong>release-ready</strong> when every constraint is Cleared or N/A. The sticky banner shows green when ready, amber when constraints are still open, and red when on hold.</li>
        <li>When the last open constraint clears, the suite offers to mark the package <strong>Issued</strong>.</li>
        <li>If a constraint reopens after the package is Issued, you log the hold (what reopened, details, optional doc link &amp; photo) and the status drops to <strong>Issue (Hold)</strong>.</li>
      </ul>` },

    { id: 'disciplines', title: 'Disciplines & Split', body: `
      <h3>Disciplines &amp; Split by Discipline</h3>
      <p>Disciplines are trades (Mechanical, Electrical, Tech, …) set in <strong>SOP Step 5</strong>. The <strong>discipline strategy</strong> controls how packages handle them:</p>
      <ul>
        <li><strong>Let the planner choose per package</strong> (recommended) — pick one discipline (flat scope) or several (per-discipline scope + the <em>Split</em> option).</li>
        <li><strong>One discipline per package</strong> — each WP is single-discipline.</li>
        <li><strong>Multiple disciplines per package</strong> — scope is always split by discipline.</li>
      </ul>
      <h4>Split by Discipline</h4>
      <p>When a package covers 2+ disciplines, the <strong>⎘ Split by Discipline</strong> button breaks it into one numbered instance per discipline — <code>WP01A</code>, <code>WP01B</code>, <code>WP01C</code> (or <code>_MECH</code>/<code>_ELEC</code> suffixes, set in the SOP). The original is kept as a <strong>master / roll-up</strong>; each instance:</p>
      <ul>
        <li>becomes its own single-discipline package, issued independently;</li>
        <li>receives only the <strong>scope steps</strong> and <strong>materials tagged to that discipline</strong>;</li>
        <li>stays linked back to the master.</li>
      </ul>
      <div class="ui-help-callout">Tag material rows to a discipline <em>before</em> splitting. <strong>Untagged rows stay on the master only</strong> and won't be routed to any instance. Masters are excluded from dashboard counts so hours aren't double-counted.</div>` },

    { id: 'sizing', title: 'Sizing', body: `
      <h3>Work Package sizing</h3>
      <p>In <strong>SOP Step 5</strong> you set a typical WP <strong>size band</strong>, which sets a <strong>split threshold</strong> (max labor hours):</p>
      <table>
        <tr><th>Size band</th><th>Split threshold</th></tr>
        <tr><td>Small — 1–2 days (≈8–24 hrs)</td><td>24 hrs</td></tr>
        <tr><td>Standard — 3–5 days (≈40–80 hrs)</td><td>80 hrs</td></tr>
        <tr><td>Large — 1–2 weeks (≈80–160 hrs)</td><td>160 hrs</td></tr>
        <tr><td>Custom…</td><td>you set it</td></tr>
      </table>
      <p>In the Creator, the <strong>Est. Hrs.</strong> field is checked live against the threshold. Within range you see the target band; over it you get an amber warning — <em>"⚠ … exceeds the …-hr split threshold — consider breaking this package down"</em> — and a nudge to split by discipline where that applies. It's a guide, not a hard block: you can proceed if it's intentional.</p>` },

      <h3>Dashboard &amp; metrics</h3>
      <p>The dashboard aggregates every (non-master) package in the active project. Open it from the home page, the suite's <strong>📊 Dashboard</strong> tab, or the Creator header.</p>
      <h4>Metric cards (click to filter)</h4>

      <h3>Frequently asked questions</h3>
      <h4>The Work Package Creator is locked — why?</h4>
      <p>The SOP for the active project isn't complete yet. Finish SOP Configuration and click <strong>✓ SOP complete</strong> on the last step; the Creator unlocks and the home card turns green.</p>
      <h4>Why can't I set a package to Issued?</h4>
      <p>At least one constraint is still <strong>Open</strong>. Clear or mark N/A every constraint — the release banner turns green — and the suite will offer to issue it.</p>
      <h4>My package's materials didn't all carry over when I split it.</h4>
      <p>Only material rows <strong>tagged to a discipline</strong> are routed to that instance. Untagged rows stay on the master. Tag them before splitting.</p>
      <h4>Why don't split masters show in the dashboard totals?</h4>
      <p>Masters are roll-ups; counting them would double-count their hours and packages. The individual instances are counted instead.</p>
      <h4>Will I lose my work if I close the browser?</h4>
      <p>No — drafts auto-save locally per project and reload next time. Use <em>Export (JSON)</em> for a backup or to share with a teammate.</p>
      <h4>Does each project keep its own data?</h4>
      <p>Yes. SOP and Work Packages are scoped to the active project; switching projects loads that project's own set.</p>
      <h4>How do I report a problem or suggestion?</h4>
      <p>Use the feedback / comments features (home page, SOP <em>Step Comments</em>, or the Creator's <em>Comments</em> drawer).</p>` }
