-# ISMIS Helper — Agent Guide
-
-Guidance for AI coding agents and contributors working in this repository.
-
-## What this is
-
-A Firefox/Chrome **MV3** extension that automates the USC ISMIS student portal
-(`ismis.usc.edu.ph`): auto-login, privacy-policy auto-accept, and a **Study Load
-PDF** export that visually matches the official document (bundled **Segoe UI**
-fonts, USC logo, course table, units total).
-
-No build step is required for the source itself; `scripts/build.js` only packages
-the two browser variants into `dist/`.
-
-## Commands
-
-```bash
-npm install                       # dev deps (only needed for tests)
-npm test                          # run the test suite (node --test)
-node scripts/build.js all         # build both browser zips -> dist/
-node scripts/build.js firefox     # build just firefox
-node scripts/build.js chrome      # build just chrome
-node scripts/build.js all --version 1.3.0   # versioned zips
-npm run build                     # shorthand for `node scripts/build.js all`
-```
-
-Never edit anything under `dist/` — it is generated and gitignored.
-
-## Repo layout
-
-- `manifest.json` — **Firefox** manifest (the single source of truth). The Chrome
-  manifest is derived at build time.
-- `background.js` — message handler; builds the PDF via `pdf.js` and downloads it.
-  Also has the cross-browser `browser.*`/`chrome.*` alias shim at the top.
-- `content.js` — runs on ismis.usc.edu.ph: auto-login, privacy modal auto-accept,
-  scrapes the study load, injects the on-page **Download PDF** button.
-- `parsers.js` — pure HTML-scraping helpers (study load table, profile page,
-  offered courses, filtering/summing).
-- `pdf.js` — builds the PDF; exports `buildStudyLoadPdf` plus formatting helpers
-  (`compactProgram`, `formatSchedule`, `formatFullName`, `formatTeacher`,
-  `deriveDateRange`, `truncateToWidth`).
-- `popup.html` / `popup.js` / `popup.css` — settings UI (profiles, master toggle,
-  PDF settings like truncation and Year Level).
-- `libs/` — vendored `pdf-lib.min.js` and `fontkit.min.js` (needed to embed the
-  custom Segoe UI fonts).
-- `assets/` — the transparent PNG logo and `fonts/Segoe-UI*.ttf`.
-- `icons/` — 16/32/48/128 extension icons.
-- `scripts/build.js` — zero-dependency packaging script for both browsers.
-- `.gitea/workflows/build.yml` — Gitea Actions: builds + tests on push, creates a
-  Gitea Release with both zips when a `v*` tag is pushed.
-- `test/` — `node --test` suite (`pdf.test.js`, `parsers.test.js`).
-
-## Build model (Firefox vs Chrome)
-
-- The **root is the Firefox source**: `manifest.json` uses `background.scripts`
-  (multiple files) and `browser.*` APIs.
-- The **Chrome build** derives a manifest with
-  `"background": { "service_worker": "background.chrome.js" }` and assembles that
-  single worker by concatenating, in order:
-  `libs/fontkit.min.js` → `libs/pdf-lib.min.js` → `pdf.js` → `background.js`.
-- The cross-browser shim (top of `background.js`, `content.js`, `popup.js`) aliases
-  `browser` to `chrome` when the former is absent. It is a no-op in Firefox.
-- `scripts/build.js` **excludes** `test/`, `docs/`, `scripts/`, `dist/`, and
-  `.git` from the packaged output.
-
-## Conventions & constraints
-
-- Plain ES5+ JavaScript. No framework, no bundler, no build step for the source.
-- Use Promise-based `browser.*` APIs (Chrome MV3 supports `browser.*`; the shim
-  covers builds that only expose `chrome.*`).
-- Login profiles are stored **plaintext** in `browser.storage.local`. At most one
-  profile is enabled at a time; a master `enabled` toggle disables all behavior.
-- The on-page **Download PDF** button must never touch another window's DOM; it
-  sends a message to the background which downloads via
-  `browser.downloads.download({ saveAs: true })` (blob → object URL).
-- If you change `pdf.js` layout constants, verify against the reference PDF
-  (`/Users/adrianbonpin/Downloads/BSIT - Y3S1 - Study Load.pdf`) and re-check the
-  position measurements, since offsets can be font-metric dependent.
-- Keep `docs/` and `dist/` out of git (they are ignored).
-
-## Workflow
-
-1. Run `npm test` before and after changes.
-2. Build (`npm run build`) to make sure both variants assemble.
-3. Manually load `dist/firefox` in Firefox (`about:debugging`) and `dist/chrome`
-   in Chrome (`chrome://extensions`) to verify PDF generation.

-# ISMIS Helper
-
-A lightweight **[Firefox](https://addons.mozilla.org/)** / **[Chrome](https://chromewebstore.google.com/)**
-extension for the USC ISMIS student portal that:
-
-- Auto-fills and auto-submits your login.
-- Auto-accepts the privacy-policy modal.
-- Exports a **Study Load PDF** that matches the official layout — bundled **Segoe UI**
-  fonts, the USC logo, the course table, and the units total.
-
-One codebase builds for **both browsers** (see [Build](#build)).
-
-## Install
-
-> Temporary/development install. For distribution, publish the built zips to
-> Firefox AMO and the Chrome Web Store — they are store-ready.
-
-### Firefox (load temporary add-on)
-
-1. Build the Firefox variant (or download `ismis-helper-firefox.zip` from CI):
-   ```bash
-   node scripts/build.js firefox
-   ```
-   The output is at `dist/ismis-helper-firefox.zip` (unzip it, or use `dist/firefox/`
-   directly).
-2. Open `about:debugging` in Firefox.
-3. Click **This Firefox** → **Load Temporary Add-on…**.
-4. Select `dist/firefox/manifest.json`.
-5. Open `https://ismis.usc.edu.ph` and use the extension.
-
-### Chrome (load unpacked)
-
-1. Build the Chrome variant (or download `ismis-helper-chrome.zip` from CI):
-   ```bash
-   node scripts/build.js chrome
-   ```
-2. Unzip `dist/ismis-helper-chrome.zip` (or use `dist/chrome/` directly).
-3. Open `chrome://extensions` in Chrome.
-4. Enable **Developer mode** (toggle, top-right).
-5. Click **Load unpacked** and select the unzipped `dist/chrome` folder.
-6. Open `https://ismis.usc.edu.ph` and use the extension.
-
-> For a persistent install, package and publish via Firefox AMO / Chrome Web Store
-> with the same built zips.
-
-### Distribute to real users
-
-#### Firefox (self-hosted, temporary)
-
-> **Note:** Firefox blocks unsigned extensions for normal installs. The proper
-> fix is to sign the add-on via **addons.mozilla.org (AMO)** and publish it there
-> (or self-host a signed `.xpi`). AMO is currently **under maintenance**, so until
-> it returns, the only way to install the unsigned build is to lower Firefox's
-> signing check on each user's machine. This is a per-user browser setting and is
-> **not** suitable for a broad audience — use it for personal / small-group use.
-
-1. Build the Firefox variant (or download `ismis-helper-firefox.zip` from a release):
-   ```bash
-   node scripts/build.js firefox
-   ```
-2. In Firefox, open `about:config` and accept the warning.
-3. Search for `xpinstall.signatures.required` and set it to **`false`**.
-4. **Restart Firefox** for the change to take effect.
-5. Install the add-on from the release zip: drag `ismis-helper-firefox.zip` into
-   Firefox (or File → Open File… and select it).
-
-> When AMO is back online, prefer the signed route: publish the same zip to AMO
-> (or sign it with `web-ext sign`) so users install it normally without touching
-> `about:config`.
-
-#### Chrome (self-hosted)
-
-Chrome does **not** require signing for normal installs. Users can install the
-built `ismis-helper-chrome.zip` directly:
-
-1. Download `ismis-helper-chrome.zip` from a release and unzip it.
-2. Open `chrome://extensions`, enable **Developer mode**, and click **Load unpacked**.
-3. Select the unzipped folder.
-
-> For a store experience, publish the same zip to the Chrome Web Store (one-time
-> $5 developer registration).
-
-## Features
-
-- **Saved login profiles** (stored in `browser.storage.local`) — only one enabled at
-  a time, with a master on/off toggle.
-- **One-click Download PDF** button on the Study Load page.
-- PDF settings in the popup:
-  - Truncate long course descriptions to match the official PDF (default on).
-  - Show/hide `Year Level`, and set a custom Year Level value.
-- **Bundled Segoe UI fonts** for a 1:1 look with the official document.
-- Builds and packages automatically via Gitea Actions (zips + versioned releases).
-
-## Build
-
-Requires **Node.js** (the `build.js` script itself is dependency-free; `npm install`
-is only needed to run the tests).
-
-```bash
-npm install                     # dev deps for tests
-npm test                        # run the test suite
-npm run build                   # build both -> dist/*.zip
-node scripts/build.js all       # build both explicitly
-node scripts/build.js chrome    # just chrome
-node scripts/build.js all --version 1.3.0   # versioned zips
-```
-
-**CI (Gitea Actions):** on every push, both zips are built, tests run, and the
-zips are uploaded as artifacts. When you push a `v*` tag (e.g. `v1.3.0`), it
-additionally creates a **Gitea Release** with both versioned zips attached.
-
-## Settings
-
-Open the extension popup to:
-- Manage login profiles (add / edit / enable).
-- Toggle the master on/off switch.
-- Set PDF options: truncate descriptions, show/hide `Year Level`, custom Year Level.
-
-## Data & privacy
-
-- Auto-login stores your portal credentials **in plaintext** on your own device.
-- This is a personal-use helper for the university portal; use it only with your
-  own account.
-
-## Development
-
-See [`AGENTS.md`](AGENTS.md) for the repository layout, build model, and coding
-conventions for this project.

+# ISMIS Helper — Firefox Extension Design
+
+**Date:** 2026-08-18
+**Status:** Approved
+**Target site:** `https://ismis.usc.edu.ph` (USC ISMIS student portal)
+
+## Overview
+
+A personal Firefox extension (Manifest V3, no build step) that improves the USC ISMIS
+student portal experience. It provides three features:
+
+1. **Auto-login** — auto-fill and auto-submit the login form from a saved profile.
+2. **Auto-accept Privacy Policy** — dismiss the recurring privacy-policy modal.
+3. **Study Load PDF** — an on-page "Download PDF" button on the Study Load page that
+   generates a PDF replicating the official ISMIS Study Load document (Letter size,
+   with course descriptions looked up from the Offered Courses endpoint) and
+   downloads it directly.
+
+A single **master toggle** disables all extension behavior on the portal.
+
+## Architecture
+
+Single MV3 extension, plain JavaScript, no bundler. No background script — all logic
+runs in the content script (scraping and print-document building happen in-page).
+
+```

+```
+
+### Permissions (manifest.json)
+- `storage` — persist profiles and the master toggle.
+- `downloads` — save the generated Study Load PDF.
+- `host_permissions` — `https://ismis.usc.edu.ph/*` for the content script.
+- Background loads `libs/pdf-lib.min.js` + `pdf.js` via `background.scripts`.
+
+## Background script
+- `background.js` handles the `generate-pdf` message from the content script:
+  builds the PDF via `ISMIStools.buildStudyLoadPdf`, wraps the bytes in a Blob,
+  downloads via `browser.downloads.download({ saveAs: true })`, and revokes the
+  object URL when the download reaches `complete`/`interrupted` (and on failure).
+
+## Component 1 — Auto-login
+
+- Content script runs on `https://ismis.usc.edu.ph/Account/Login`.
+- Reads the active (enabled) profile from `browser.storage.local`.
+- Locates the username and password input fields (`name`/`id` = `Username` /
+  `Password`, with fallback variants).
+- Fills both fields, then submits the form (auto-submit).
+- If no profile is enabled, or the master toggle is off, does nothing.
+
+## Component 2 — Auto-accept Privacy Policy
+
+- On any portal page, if the privacy modal `#myModal` is present and visible:
+  - Check the `#Confirmation` checkbox ("I have read and understood the Privacy
+    Policy Statement").
+  - Click the `#Submit` button (Continue), which is disabled until the checkbox is
+    checked.
+- Gated by the master toggle.
+
+## Component 3 — Profiles
+
+- Stored in `browser.storage.local` under key `profiles` as an array of:
+  `{ id, name, username, password, enabled }`.
+- Popup provides add, edit, delete, and enable/disable per profile.
+- Only one profile can be enabled at a time (enabling one disables the others);
+  that profile is used for auto-login.
+- Master toggle stored under key `enabled` (boolean).
+
+## Component 4 — Study Load PDF
+
+### On-page button
+- The content script watches the Study Load page (`#StudyLoad`). When the course
+  table appears (after the user selects academic period/year and searches), it
+  injects a **"Download PDF"** button inline with the
+  `12.00 Units / Total Units: 18.00` footer (button on the left, units text on the
+  right, via a flex row), styled like the page's buttons (`btn green`).
+
+### Scrape
+- Parse the course table (columns: Group #, Course Code, Schedule, Faculty, Units,
+  Status) via `parseStudyLoadTable`.
+- **Header info** (full name, student ID, program, year level, semester) is scraped
+  from the **My Profile** page (`/Manage/Student`).
+
+### Filtering
+- **DISSOLVED courses are excluded** (`filterStudyLoadCourses`).
+- Total units = sum of the included courses' units (`sumUnits`).
+
+### Description lookup
+- For each unique course code, POST to
+  `https://ismis.usc.edu.ph/CourseSchedule/CourseScheduleOffered` with the
+  `__RequestVerificationToken` and selected `AcademicPeriod`/`AcademicYear`, then
+  parse the returned table for the **Course Description**.
+- If lookup fails for a course, the description is left blank and generation
+  continues.
+
+### PDF generation
+- `pdf.js` (`buildStudyLoadPdf`, using **pdf-lib**) builds a Letter-size (612×792pt)
+  PDF replicating the official layout: title block (STUDENT'S STUDY LOAD, semester,
+  date range, date enrolled), student info row (ID, name, program, year level), the
+  course table (GROUP, COURSE, COURSE DESCRIPTION, TEACHER, UNITS, NOTE — NOTE is
+  the status), and a footer (total units, "Printed by: …"). Multi-page
+  pagination re-draws the table header. NOTE column is wide enough for `REGULAR`.
+- The content script sends the data to the background (`generate-pdf`), which
+  downloads the PDF via the `downloads` API (`saveAs: true`).
+
+## Data flow
+
+```
+Study Load page ──▶ content script (scrape + filter DISSOLVED + description lookup)
+                       │
+                       ▼  browser.runtime.sendMessage({ type: 'generate-pdf', data })
+              background.js (pdf-lib buildStudyLoadPdf)
+                       │
+                       ▼
+              browser.downloads.download → Study Load PDF file
+```
+
+## Error handling
+
+- Master toggle off → no extension behavior on the portal.
+- No enabled profile → no auto-login.
+- Description lookup fails for a course → blank description, PDF still generated.
+- No enrolled (non-DISSOLVED) courses → error toast, no download.
+- Download fails → error toast; object URL is revoked.
+
+## Testing
+
+- Node `node:test` suites: parsers (table/profile/offered-courses/filter/sum) and
+  pdf (valid Letter PDF output).
+- Load via `about:debugging` → "Load Temporary Add-on".
+- Verify auto-login on the login page.
+- Verify privacy modal auto-accept.
+- Verify profile add/edit/delete/toggle and master toggle.
+- Verify the on-page Download PDF button: appears inline with the total-units
+  footer, excludes DISSOLVED courses, and downloads a Letter-size PDF.
