# Module Map

| Path | Responsibility | Notes |
|---|---|---|
| `arr_web/auth.py` | Login credential verification and bounded attempt ledger | Environment-owned single-operator identity; dependency-free constant-time comparison; no secret logging |
| `arr_web/programmatic.py` | Upload-to-terminal coordinator | Registers the validated browser basename separately from canonical `source.xml`; no remote/model transport |
| `arr_web/booking_uploads.py`, `booking_ingestion/excel.py` | Authenticated Booking source upload and bounded raw XLSX parsing | Parser 2.0 reads Tour Code plus exact `โรงแรม`, latest-row cancellations and extracted room items with review state; coordinator/backend route contracts target drafts |
| `booking_ingestion/excel_postgres.py` | Earlier direct Booking full-source import/activation path | Its one-item immediate-accept implementation does not represent parser 2.0 review and must not be treated as the completed review repository |
| `booking_ingestion/excel_review.py`, `booking_ingestion/excel_review_postgres.py` | Editable extraction drafts and atomic reviewed-source activation | Single-operator repository uses advisory locking and a zero-pending gate; real PostgreSQL transaction/rollback acceptance passes; actor/reason/revision history is not implemented |
| `arr_web/processing_runtime.py` | PostgreSQL + OSS + processor composition | Active production processing composition |
| `arr_processing/local.py` | Bounded subprocess and output manifest extraction | Never exposes stdout/stderr |
| `arr_processing/policy.py` | Frozen processor/rule identity | Neutral, reusable loader |
| `arr_ingestion/validation.py` | Strict artifact/result validation | Runs `validate_daily.py` on success |
| `arr_ingestion/postgres.py` | Atomic Finance commit and lifecycle state | Four retries only for transient SQLSTATEs |
| `arr_storage/aliyun_oss_v2.py` | Encrypted/unversioned OSS adapter | Writes all objects private |
| `arr_web/downloads.py` | OSS daily + controlled local report download routing | Rechecks metadata, size and SHA-256 |
| `arr_web/job_trace.py` | Programmatic persisted-fact trace | No external trace store |
| `arr_web/app.py`, `arr_web/repository.py`, `arr_web/company_jobs.py` | Authenticated portal routes plus public H5 aggregate routes, paged history reads and read-only history-month discovery | Default-deny login gate protects the desktop/API/download surface; purpose-built `/api/public/h5/*` exposes only sanitized aggregate metrics; daily/monthly counts and rows share a repeatable-read snapshot; `/api/history-months` merges daily/monthly database counts with company job-state counts; company totals/slices share one lock |
| `arr_web/server.py` | Standard-library HTTP transport | Dispatches GET/POST/PATCH/DELETE with one bounded body reader; real socket tests cover review update/delete and missing/oversized lengths |
| `arr_web/static/login.html`, `login.css`, `login.js` | Responsive ARR login gateway | Labeled form, password visibility, generic inline failures, safe desktop/H5 return target and reduced-motion support |
| `arr_web/static/app.js`, `arr_web/static/h5.js` | Authenticated desktop and anonymous-capable H5 client state, rendering and polling | Desktop daily/monthly/company histories own independent viewing-month state and default to the latest non-empty month; company generation month remains separate. H5 reads only public aggregate endpoints and may retain optional logout for an authenticated session. Desktop also includes 50-row Booking draft review/edit, the draft's validated uploaded filename below the review title, individual/all-visible selection, count-aware in-page delete confirmation and activation; company generation keeps the fixed five-company context beside the page title, a four-card upload/period setup row, cumulative CO display labels, short centered period actions and an in-page generation confirmation dialog; session-expiry redirect and CSRF logout remain shared; monthly versions auto-refresh the selected viewing month every four seconds |
| `monthly_reports/worker.py` | Dedicated outbox consumer | Lease/reclaim, retry/dead-letter, success acknowledgement after activation |
| `monthly_reports/repository.py` | Monthly snapshot and publication repository | Derives scope from `ARRIVAL`; persists metadata/lineage/artifact identities |
| `monthly_reports/xlsx/build_workbook.mjs` | Monthly XLSX builder and reopen validator | Exact row-relative `TOTAL PRICE` formulas only in column S |
| `monthly_reports/`, `company_reports/`, `channel_analytics/` | Downstream reports/BI | Consume accepted Finance facts |
| `database/012_monthly_report_publication.sql` | Additive metadata-only publication schema | Applied after immutable 008–011 baseline |
| `database/014_booking_current_source_batch.sql` | Booking full-workbook current-source pointer and view scoping | Formally applied on 2026-07-31; batch 1 remains selected |
| `database/015_booking_excel_review_drafts.sql` | Item-level Booking extraction draft state | Formally applied and empty; basic latest-state review only, with no actor/reason/revision history and no DB-enforced zero-pending activation |
| `compose.yaml`, `deploy/` | Web-login + Caddy-HTTPS template and worker deployment boundary | Requires Web credentials for the desktop/operational surface; public H5 aggregate routes and `/healthz` remain anonymously reachable; no MCP port/domain/service |
| `tests/test_arr_programmatic.py` | Real success/failure vertical slices | Primary ARR2.0 acceptance proof |

Historical ARR1 compatibility modules and migrations remain for audit/tests but are not imported, installed or deployed
by the active ARR2.0 entrypoint.
