Summary

This PR addresses and fixes character corruption (flattening non-ASCII characters such as —, ’, ·, \u00A0, ®, and emojis to literal ?) when Google Apps Script commits notes to GitHub via the Contents API.

Root Cause

Utilities.base64Encode(updatedContent) was invoked with a JavaScript string instead of raw bytes. In Google Apps Script, string encoding defaults to US_ASCII, turning all unmappable Unicode characters across the entire note file into 0x3F (?).

Key Changes

  1. UTF-8 Byte Encoding: Converted all Base64 encode and decode paths to use Utilities.newBlob(...).getBytes() and Utilities.newBlob(...).getDataAsString().
  2. Rule 6 Mojibake Guards: Added RULE6_PATTERNS, assertClean_, and assertNoAsciiReplacement_ pre-commit assertions in both gmail-ai-classifier and drive-ai-ingester.
  3. Comprehensive Tests: Added src/gmail-ai-classifier/tests/github-sync.test.js validating UTF-8 round-trip preservation and assertion behaviors.
  4. CI & Quality: 100% test pass rate with coverage exceeding all repo thresholds (Lines 99.04%, Statements 98.70%, Branches 90.49%, Functions 98.29%).

Summary by CodeRabbit

  • New Features
    • Added AI-powered Gmail classification across seven domains, with Gmail labels, retention cleanup, and GitHub activity summaries.
    • Added AI-powered Google Drive tagging with document metadata, scheduled processing, and optional GitHub synchronization.
    • Added tools to restore damaged email headers, clean up conflicting legacy labels, and audit duplicate sender filters.
    • Routed HoneyBeeHam email and Drive records to a dedicated household summary.
  • Documentation
    • Added setup guidance, taxonomy definitions, and a proposal for semantic email classification.
  • Quality Improvements
    • Expanded automated tests and coverage reporting, with safeguards against corrupted text in synchronized summaries.

CodeAnt-AI Description

Add Gemini-powered Gmail classification, Drive tagging, and safe GitHub note synchronization

What Changed

  • Gmail threads are classified into seven household domains, labeled with a single domain and optional sub-label, and marked as processed.
  • High-confidence sender classifications can create permanent Gmail filters while avoiding duplicate rules.
  • Google Drive documents are analyzed, tagged with domain and metadata, marked as indexed, and processed automatically on a recurring schedule.
  • Gmail and Drive summaries are synchronized to GitHub notes, including automatic note creation, section-aware insertion, duplicate-commit prevention, and retries for transient failures.
  • GitHub note updates preserve UTF-8 characters such as em dashes, curly quotes, symbols, non-breaking spaces, and emojis; corrupted text is rejected before committing.
  • Added extensive tests for classification outcomes, filtering, Drive/GitHub synchronization, encoding preservation, retry behavior, and scalability.

Impact

✅ Automatic seven-domain email organization
✅ Searchable Drive document tags and summaries
✅ No corrupted Unicode in GitHub notes
✅ Fewer duplicate Gmail filters and note entries

Code Review

This pull request introduces a Google Drive AI Ingestion engine and a Gmail AI Classifier engine, both utilizing Gemini/Gemma models to categorize files and emails into a 7-domain taxonomy and sync summaries to GitHub. Feedback on the changes suggests implementing an automatic retry mechanism for HTTP 409 version conflicts in the Drive ingester's GitHub sync, extracting the Drive ingester's core logic into a testable Node.js module for Jest unit testing, and optimizing the Gmail classifier by avoiding expensive Session.getEffectiveUser().getEmail() API calls inside loops.

This project keeps all core logic directly inside Code.gs without extracting it into a testable Node.js module. This violates the general rule: "For Google Apps Script projects, extract Node.js-testable logic from code.gs into src/<script-name>/src/index.js using a service injection pattern to allow unit testing with Jest, while keeping code.gs as a thin entry point."

Please extract the helper functions (such as analyzeDocumentWithAi, applyDualLayerTagsToDriveFile, and extractFileContentText) into src/drive-ai-ingester/src/index.js using a service injection pattern, and write unit tests for them using Jest, similar to the architecture used in gmail-ai-classifier.

The concrete correctness bugs in this module (tagging-status gating, GitHub 409 retry, concurrency lock, content-extraction gating) were fixed inline in Code.gs/GitHubSync.gs in this pass. The full architectural extraction of the helpers (analyzeDocumentWithAi, applyDualLayerTagsToDriveFile, extractFileContentText, …) into a service-injected src/index.js with Jest coverage is a larger refactor tracked separately in #604 to keep this fix pass minimal.

80-84: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Keep Utilities.base64Decode byte-array compatible for charset arguments.

Google Apps Script returns Byte[] for both overloads. The mock returns a string for US-ASCII and UTF-8, so tests that exercise the charset overload can miss type-dependent failures. Current consumers in src/gmail-ai-classifier/src/index.js, src/gmail-ai-classifier/gitHubSync.gs, and src/drive-ai-ingester/GitHubSync.gs call base64Decode without a charset, so this is not a current production-path failure.

Remove the charset-specific string returns:

   base64Decode: (encoded, charset) => {
     const buf = Buffer.from(encoded || '', 'base64')
-    if (charset === 'US-ASCII' || charset === 'ASCII') {
-      return buf.toString('ascii')
-    }
-    if (charset === 'UTF-8' || charset === 'utf-8') {
-      return buf.toString('utf8')

     return Array.from(buf)

Use the required GAS module layout and extract its testable logic.

AGENTS.md requires each script to use lowercase code.gs, config.gs, and src/index.js. It also requires GAS logic to be extracted, exported with module.exports, and written to accept injected GAS services. This module instead contains Code.gs and Config.gs, has no src/index.js, and keeps extractJsonSubstring, parseRetryDelayMs, getNotePathForDomain, and formatDriveIngestionEntry inside Code.gs.

Rename the files, extract the testable logic into src/index.js, export the functions needed by the entry point and tests, inject GAS services, and add Jest tests.

The uppercase basenames alone do not establish a Jest or coverage failure: testMatch matches test filenames, while collectCoverageFrom uses src/**/*.{js,ts,gs}. The layout and extraction requirements apply independently.

Deferred to #604: the GAS module-layout requirement (lowercase code.gs/config.gs, extraction of extractJsonSubstring/parseRetryDelayMs/getNotePathForDomain/formatDriveIngestionEntry into src/index.js with injected services + Jest tests) is a substantial restructure. This pass fixed the functional defects inline; the extraction is scheduled as its own change to avoid a large, risky refactor mid-review.

@don-petry, thanks for the context. Keeping the module-layout finding open makes sense because the extraction and Jest tests remain deferred to #604. I will not treat the inline functional fixes as a fix for this finding.

Move GitHub repository coordinates into config.gs.

AGENTS.md requires script configuration values to live in src/<script-name>/config.gs. src/gmail-ai-classifier/src/index.js and gitHubSync.gs each hardcode the repository owner and name. Move these values into config.gs and use them in both URL builders. The current literals match, but the duplicate sources can drift.

Deferred to #604. Moving GITHUB_REPO_OWNER/GITHUB_REPO_NAME into config.gs interacts with the service-injection pattern (the Jest-tested src/index.js cannot require a GAS config.gs global), so the clean fix is part of the config-centralization work tracked there rather than a spot change here. The literals currently match across the modules.

@don-petry, thanks for the context. The service-injection pattern makes a direct config.gs reference from the Jest-tested src/index.js unsuitable. Since the repository coordinates currently match, deferring config centralization to #604 is reasonable. I’ll leave this finding open for that work.

Learning: In `src/gmail-ai-classifier/src/index.js`, the Jest-tested JavaScript core uses injected services and cannot directly `require` the Google Apps Script global `src/gmail-ai-classifier/config.gs`. Centralizing GitHub repository coordinates across that core and `src/gmail-ai-classifier/gitHubSync.gs` requires an approach compatible with service injection.

🤖 dev-lead: rebase attempted but aborted — needs human decision

I attempted to rebase this branch onto main to clear the merge conflicts, but the conflict is not safe to resolve mechanically. I aborted the rebase and pushed nothing — the branch is unchanged.

What actually conflicts

main has grown an independent implementation of the same module this PR develops, src/gmail-ai-classifier/. Since this branch diverged, main merged:

None of those commits exist in this branch's history, so the two sides are genuinely divergent — not a stale snapshot I can simply overwrite.

code.gs is the clearest example:

main (#530) this PR (tip)
code.gs size 443 lines 1009 lines
Taxonomy domain 04_Family_Health_School 04_Family_Health (realigned)
Prompt rules detailed numbered rules 1–11 (newsletters, school portals, beekeeping, etc.) rewritten
Actions spam → moveToTrash, archive → moveToArchive not present in the same form
Models gemma-4-31b-it, gemini-3.0-flash cascading 3.8-flash → 3.1-flash
Note paths household-vault/kids/index.md etc. realigned to household

Taking this PR's version wholesale would silently drop #530's merged production behavior (the 2-way rules sync engine, spam→trash / archive actions, and the detailed classification prompt rules). Merging them line-by-line requires product decisions I shouldn't make on your behalf, and it would repeat across ~74 replayed commits while still needing to satisfy the 99% line / 85% branch coverage gates.

Conflicting files: src/gmail-ai-classifier/{code.gs, config.gs, README.md, tests/code.test.js} and docs/proposals/proposal-001-ai-gemini-semantic-classifier.md.

What I need from a human

Please decide how #530's work should be reconciled with this PR:

  1. Supersede — this PR intentionally replaces feat(classifier): add tag-based retention and 2-way rules sync engine #530's engine (retention + 2-way rules sync). If so, confirm the sync engine and trash/archive actions are deliberately dropped, and I can rebase taking this branch's version.
  2. Preserve/merge — feat(classifier): add tag-based retention and 2-way rules sync engine #530's features must survive. Then this branch needs to adopt main's module and re-apply its changes on top (likely easier as a fresh feature branch off current main), rather than a mechanical rebase.
  3. Merge selectively — tell me which feat(classifier): add tag-based retention and 2-way rules sync engine #530 behaviors to keep and I'll integrate them.

Note for whoever retries

The working checkout was a shallow clone, which made main look like a single unrelated root commit (empty merge-base, ~370 phantom conflicts). Run git fetch --unshallow origin first — after that the real merge-base (f61ea03) appears and main is 29 commits ahead.

Dev-Lead — rebase (no-changes)

Agent reasoning
PR: #584
Rebased onto: main — ABORTED (not safe to complete)
Conflicts resolved: 0 files (rebase aborted intentionally)
Blocker: `main` and this PR contain divergent, independently-developed
implementations of src/gmail-ai-classifier/. main merged #530 (tag-based
retention + 2-way rules sync engine), #512, #511, #492 — none in this
branch's history. Reconciling them requires product decisions and would
risk silently dropping #530's merged production behavior, so per the
"abort and comment if unsafe" constraint I stopped and escalated.
Conflicting files:
- src/gmail-ai-classifier/code.gs (443 lines on main vs 1009 here; different
  taxonomy, prompt rules, models, trash/archive actions)
- src/gmail-ai-classifier/config.gs, README.md, tests/code.test.js
- docs/proposals/proposal-001-ai-gemini-semantic-classifier.md
Push: not performed (branch unchanged, still at 2bddf7f)
Action taken: posted an explanatory comment on the PR requesting a human
decision on how to reconcile #530.
```
**Two things worth flagging beyond the task:**
1. **Shallow-clone trap** — the worktree was a shallow clone, so `origin/main` initially looked like a single unrelated root commit (empty merge-base, ~370 phantom "Initial commit" conflicts on LICENSE/README). Had I resolved those blindly, the result would have been catastrophic. I ran `git fetch --unshallow origin` first, which revealed the real merge-base (`f61ea03`) and the true 80-vs-29 divergence. I noted this in the PR comment for whoever retries.
2. **The real conflict is a product decision, not a mechanical one.** This PR (#584) and `main` both grew the `gmail-ai-classifier` module independently. PR #584 intentionally changed the taxonomy (`04_Family_Health_School` → `04_Family_Health`), models, and prompt rules, while `main`'s #530 added a retention + 2-way rules sync engine and `trash`/`archive` actions. Someone needs to confirm whether #584 supersedes #530 or must incorporate it before the rebase can proceed. I laid out three concrete options in the comment.
