+description: Strict HR-ATS backend house style — layering, routes, serializers, auth
+globs: backend/**/*.py
+alwaysApply: false
+---
+
+# HR-ATS Backend — singular pattern (mandatory)
+
+Match existing modules (`users/`, `inbox/`) exactly. Do not introduce alternate frameworks, layers, or response shapes.
+
+## Package layout (every domain)
+
+```
+backend/<domain>/
+  app.py          # routes only — HTTP in/out
+  views.py        # service class — business logic
+  models.py       # SQLModel table + classmethod DB accessors
+  serializers.py  # hand-rolled dict builders (no Pydantic response models)
+  plugins.py      # pure helpers (hash, JWT, clean payload) — NO FastAPI imports
+  permissions.py  # OAuth2 scheme + Depends aliases (auth domains only)
+```
+
+- Mount with bare `router = APIRouter()`; register in `main.py` via `app.include_router(...)`.
+- No package `__init__.py`; run uvicorn from `backend/` so imports are top-level (`users.app`, `db_setup`).
+- Config: `load_dotenv()` + `os.getenv(...)` in the module that needs it. Do not extend `db_setup.Settings` for non-DB keys.
+
+## Layer duties (strict)
+
+| Layer | Owns | Must NOT |
+|---|---|---|
+| `app.py` | Routes, request Pydantic models (inline), `JSONResponse`, call serializers for HTTP payloads, inject `CurrentUser` / `session` | Business rules, DB queries, JWT encode logic beyond calling plugins |
+| `views.py` | Validate rules, call models, raise `HTTPException`, return ORM rows or serialized dicts for CRUD | Build login/token HTTP envelopes; call `serialize_token` |
+| `models.py` | Table fields, `select`/`insert`/`update`/`soft_delete`, `selectinload` when relations are needed | HTTPExceptions, serializers, FastAPI |
+| `serializers.py` | `serialize_*` → plain `dict` (`str(uuid)`, `.isoformat()` dates, never password) | DB access, Depends |
+| `plugins.py` | Pure functions; raise library errors (e.g. `jwt.*`), not HTTP | Import FastAPI |
+| `permissions.py` | `OAuth2PasswordBearer`, `get_current_user`, `CurrentUser = Annotated[...]`, `require_permission` | Route handlers |
+
+## Route pattern (`app.py`)
+
+- Verb-in-path: `/users/create`, `/users/fetch`, `/users/login` — not `/auth/token`, not REST nouns-only.
+- Every handler uses this wrapper:
+
+```python
+try:
+    service=User(session=session)
+    data=await service.some_method(...)
+    return JSONResponse(content={"data":data,"status_code":200})
+except HTTPException:
+    raise
+except Exception as e:
+    raise HTTPException(status_code=500,detail=str(e))
+```
+
+- List fetch: `{"data":items,"total":total,"status_code":200}`; single-by-id: `total: 1`.
+- Login/refresh: build tokens in the route, then serialize:
+
+```python
+user=await service.authenticate_user(...)
+tokens=serialize_token(create_access_token(user),create_refresh_token(user),user)
+return JSONResponse(content={**tokens,"status_code":200})
+```
+
+- Request schemas live **inline** in `app.py` (`UserCreate`, `TokenRefresh`, …). Not in `serializers.py`.
+- Dependencies: default form `session: AsyncSession = Depends(get_session)` unless `Annotated` is required (auth form / `CurrentUser` before other defaults).
+- Tight spacing house style: `service=User(session=session)`, `detail=str(e)`, `key=value` in calls — match neighbors, do not “pretty-reformat” whole files.
+
+## Service pattern (`views.py`)
+
+```python
+class User:
+    def __init__(self,session:AsyncSession):
+        self.session=session
+
+    async def create_user(self,payload):
+        ...
+        return serialize_user(user)   # CRUD returns serialized dict
+```
+
+- Untyped method args (match existing). Raise `HTTPException(status_code=...,detail="...")`.
+- Auth methods (`authenticate_user`, `refresh_access_token`) return the **ORM user** only — never `serialize_token`.
+- After email lookup that lacks `selectinload(role)`, re-fetch via `get_user_by_id` before anything that touches `user.role`.
+
+## Model accessors (`models.py`)
+
+- `@classmethod async def get_* / insert_* / update_* / soft_delete_* / count_*`.
+- Soft delete: set `is_deleted=True`, `is_active=False`.
+- Use `selectinload(cls.role)` on fetches that will be serialized with role fields.
+- Commit inside model write methods (existing pattern).
+
+## Auth pattern
+
+- Access + refresh JWTs via `plugins` (`type` claim must be checked in `decode_token`).
+- `permissions.CurrentUser` on every protected `/users/*` route; login + refresh stay open.
+- `get_current_user`: decode access → DB load by `sub` → reject missing/deleted/inactive → `serialize_user`.
+- Login uses `OAuth2PasswordRequestForm`; username field carries email.
+- OAuth2 fields (`access_token`, `refresh_token`, `token_type`, `expires_in`) at **response root**; user under `data`.
+- `tokenUrl="users/login"` (no leading slash).
+- No FastAPI in `plugins.py`. Translate `jwt.PyJWTError` → 401 in `permissions` / `views`.
+
+## Dependencies / env
+
+- Pin in `requirements.txt` under comment banners with trailing rationale comments.
+- Secrets in `backend/.env`; document keys in `backend/.env.example`.
+- JWT times: `datetime.now(timezone.utc)` only (never naive `datetime.now()` for token `iat`/`exp`).
+
+## Hard bans
+
+- No new abstraction layers (repositories, use-cases, DTOs beyond inline Pydantic requests).
+- No Pydantic response models; no `jsonable_encoder` for these routes.
+- No changing response envelope (`data` + `status_code`) or inventing `/api/v1` prefixes.
+- No drive-by refactors or reformatting unrelated code.
+- No RBAC second scheme — vocabulary and `require_permission` live in `users/permissions.py` only.
+- Do not touch `inbox/` when the task is `users/` (and vice versa) unless asked.
+- No `__init__.py` packages; no moving request models into `serializers.py`.
+
+## When adding a new domain endpoint
+
+1. Accessor on `models.py` if DB changes.
+2. Method on service in `views.py`.
+3. `serialize_*` in `serializers.py` if new shape.
+4. Route in `app.py` with the standard try/except + `JSONResponse`.
+5. Protect with `current_user: CurrentUser` if under an authenticated router.

+# Bulk ATS Scoring Engine
+
+One job description in, many resume PDFs in, a score-sorted leaderboard out.
+
+Resumes are extracted with `pypdf`, evaluated concurrently against the job description
+with the OpenAI Responses API, validated against a strict schema, and returned as a
+single JSON response. A failure on one resume never fails the batch.
+
+[CLAUDE.md](claude.md) is the specification this implements and remains the source of
+truth for design decisions.
+
+## Setup
+
+Requires Python 3.11+.
+
+```bash
+python -m venv .venv
+.venv\Scripts\activate          # Windows
+# source .venv/bin/activate     # macOS / Linux
+
+pip install -e ".[dev]"
+
+copy .env.example .env          # Windows
+# cp .env.example .env          # macOS / Linux
+```
+
+Put an `OPENAI_API_KEY` in `.env`. `.env` is gitignored; never commit it.
+
+> On Windows, write `.env` as UTF-8 **without** a BOM. PowerShell 5.1's
+> `Set-Content -Encoding utf8` adds one, and a BOM becomes part of the first
+> variable's name — that setting then silently reads as empty. The app parses `.env`
+> as `utf-8-sig` so it tolerates this, but other tools reading the same file will not.
+
+Run the service:
+
+```bash
+uvicorn app.main:create_app --factory --reload
+```
+
+There is deliberately no module-level `app` object. Building one at import time would
+read settings — and fail on a bad `ANTHROPIC_MODEL` — merely because something imported
+the module.
+
+## Verify the request shape before trusting it
+
+Unit tests use fakes, so they cannot prove the real API accepts the request. One live
+check does, and it costs a few cents:
+
+```bash
+python scripts/smoke_structured_output.py
+```
+
+It confirms the schema derived from `ATSScore` is accepted, that `output_parsed` comes
+back valid, and that the second call reports non-zero `cached_tokens`.
+Run it whenever you change the model or upgrade the SDK.
+
+Last verified against `gpt-5.4-mini`: both calls parsed, and call 2 served 2304 of
+2649 input tokens from cache.
+
+## API
+
+### `POST /api/v1/score`
+
+`multipart/form-data`:
+
+| Field | Type | Notes |
+|---|---|---|
+| `job_description` | text | Required, non-blank, `MAX_JD_CHARS` ceiling |
+| `resumes` | file[] | Required, `.pdf` only, `MAX_RESUMES_PER_REQUEST` / `MAX_PDF_SIZE_MB` ceilings |
+
+```bash
+curl -X POST http://localhost:8000/api/v1/score \
+  -F "job_description=Backend engineer. Required: Python, FastAPI, Docker." \
+  -F "resumes=@candidate-a.pdf" \
+  -F "resumes=@candidate-b.pdf"
+```
+
+```json
+{
+  "request_id": "2ce31ea9-29b2-4cad-a916-1a18cfc69c20",
+  "total": 2,
+  "succeeded": 1,
+  "failed": 1,
+  "results": [
+    {
+      "filename": "candidate-a.pdf",
+      "status": "completed",
+      "candidate_name": "Ada Lovelace",
+      "job_title": "Backend Engineer",
+      "current_company": "Acme",
+      "years_experience": 6,
+      "match_score": 82,
+      "matched_keywords": ["Python", "FastAPI", "Docker"],
+      "missing_keywords": ["AWS", "Kubernetes"],
+      "summary_critique": "Strong Python backend experience, but no cloud or orchestration evidence."
+    },
+    {
+      "filename": "candidate-b.pdf",
+      "status": "failed",
+      "error_code": "PDF_TEXT_UNAVAILABLE",
+      "error_message": "No usable text could be extracted from the PDF."
+    }
+  ]
+}
+```
+
+Completed results come first, sorted by `match_score` descending. Failures follow, in
+upload order. Ties keep upload order.
+
+The profile fields (`candidate_name`, `job_title`, `current_company`,
+`years_experience`) are extracted from the resume by the model and are `null`
+whenever the resume does not state them. `years_experience` uses the total stated in
+the resume when there is one, otherwise it is computed from explicitly stated dates —
+never guessed. `matched_keywords` are verified server-side against the resume text;
+a keyword the resume never mentions is dropped rather than shown as evidence.
+
+### Status codes
+
+| Code | Meaning |
+|---|---|
+| 200 | Batch processed — including batches where every candidate failed |
+| 400 | Malformed multipart request, or blank job description |
+| 413 | Too many files, or a file over the size limit |
+| 415 | A file is not a PDF |
+| 422 | Structurally valid request with an out-of-range field value |
+| 500 | Unexpected internal error |
+
+Error responses are `{"request_id", "error_code", "error_message"}`. Stack traces,
+provider response bodies, prompts, and document content never appear in them.
+
+### Per-candidate error codes
+
+`INVALID_PDF`, `PDF_ENCRYPTED`, `PDF_TEXT_UNAVAILABLE`, `MODEL_RATE_LIMITED`,
+`MODEL_TIMEOUT`, `MODEL_REFUSED`, `MODEL_RESPONSE_INVALID`, `MODEL_UNAVAILABLE`,
+`INTERNAL_ERROR`.
+
+## Configuration
+
+See [.env.example](.env.example) for the full list. Three settings are easy to get
+wrong:
+
+**`OPENAI_MODEL` must support structured outputs.** Validated at startup as a prefix
+check over known families — `gpt-5*`, `gpt-4.1*`, `o3*`, `o4*` — rather than an exact
+list, so a new point release isn't rejected on arrival. Two deliberate exclusions:
+`gpt-4o` (snapshots before 2024-08-06 lack structured outputs, and aliases hide which
+you get) and any `-chat-latest` variant (tracks the ChatGPT product surface, no
+reasoning effort). `gpt-4.1` *is* allowed but is not a reasoning model — the adapter
+detects that and omits the `reasoning` parameter instead of sending a 400.
+
+**`OPENAI_MAX_OUTPUT_TOKENS` covers reasoning tokens and the response together.** A
+small cap truncates mid-JSON and the candidate fails with `MODEL_RESPONSE_INVALID`.
+The enforced floor is 2048 and the tested baseline is 4000.
+
+**Lower `OPENAI_EFFORT`, not `OPENAI_MAX_OUTPUT_TOKENS`, to cut cost.** The token
+budget is a truncation guard, not a spend dial; effort is the spend dial.
+
+There is no `temperature` / `top_p` setting. Reasoning models reject them; the model is
+steered by the system prompt and structured outputs instead.
+
+## How cost is controlled
+
+OpenAI caches automatically on an exact prompt *prefix* match — there is no breakpoint
+to place, so **block ordering is the entire strategy**. The instructions and job
+description are byte-identical across every candidate in a batch and go first; the
+resume goes second. On the live smoke test this served 87% of input tokens from cache
+(2304 of 2649) on the second call.
+
+Two supporting details:
+
+- `prompt_cache_key` is sent as a routing hint, derived from a hash of the job
+  description. It is stable for a whole batch and never per-candidate — a
+  high-cardinality key would defeat the purpose.
+- A cache entry only becomes readable once the first response exists. If all 50
+  candidates launched at once, every one would pay full price — so `score_batch`
+  awaits the first candidate alone to prime the prefix, then fans the rest out under
+  the concurrency semaphore.
+
+This is why nothing volatile may ever enter the job-description block. A timestamp,
+request id, or filename there moves the divergence point to the front of the prompt
+and the whole batch stops hitting the cache. [test_llm.py](tests/unit/test_llm.py)
+fails if that happens.
+
+Caching has a **1024-token minimum**, so short job descriptions will not cache at all.
+
+## Development
+
+```bash
+ruff check .
+ruff format --check .
+mypy app
+pytest -q
+```
+
+No test makes a live API call. Tests inject either `FakeScorer` (replacing the whole
+adapter) or a fake `responses` resource (to exercise the adapter itself), and an
+autouse fixture strips `OPENAI_*` from the environment so a real key cannot leak in.
+
+Swapping providers is a contained change: the `Scorer` protocol in
+[app/services/llm.py](app/services/llm.py) is the only seam that touches a vendor SDK.
+Models, PDF handling, orchestration, routing, and logging are provider-agnostic.
+
+## Data handling
+
+Resumes contain personal data.
+
+* Uploads are held in memory and parsed from `io.BytesIO`. Nothing is written to disk.
+* Resume text, job-description text, prompts, and full model responses are never
+  logged. The logger emits only an explicit allowlist of keys, and exceptions are
+  recorded as a type plus `file:line:func` frames — never a formatted message, because
+  provider errors can echo request content.
+* Nothing is persisted between requests. There is no database and no queue, so
+  retention is bounded by process lifetime. **Adding any storage means writing a
+  retention and deletion policy first.**
+
+## Limitations
+
+* **Not a hiring decision.** The score is decision support. The prompt forbids
+  inferring or scoring protected characteristics, and candidates are never compared
+  against each other — each is scored independently against the same job description.
+* **Scanned and image-only PDFs fail** with `PDF_TEXT_UNAVAILABLE`. There is no OCR.
+* **Multi-column layouts extract in reading-order-ish, not exact, order.** The system
+  prompt tells the model this is an extraction artifact and not to penalise it.
+* **No authentication or rate limiting.** Both are required before public deployment.

+# Read-status sync (`/sync/*`)
+
+Tracks **which messages got read or unread** — and which were deleted — without
+re-downloading the mailbox. It sits on Microsoft Graph's **delta query**: Graph
+hands you a cursor, and every later call with that cursor returns *only* what
+changed since it was issued.
+
+Five of the six endpoints share one piece of state: a delta cursor per
+**(signed-in user + folder)**, persisted to disk so a restart doesn't re-backfill
+the whole folder. The sixth — the per-message lookup — is deliberately outside
+that machinery: it reads one id live and touches no cursor.
+
+| Method | Path | Purpose |
+| ------ | ---- | ------- |
+| GET | `/sync/read-status` | Run one sync round **now** (synchronous) |
+| GET | `/sync/read-status/changes` | Replay the last round's **full** result |
+| GET | `/sync/read-status/message/{id}` | One message's status, by id — cursor-free |
+| GET | `/sync/read-status/status` | Watcher health + cursor state |
+| POST | `/sync/read-status/watch` | Start the background poller |
+| DELETE | `/sync/read-status/watch` | Stop the background poller |
+
+All require the API bearer token, and act on the **signed-in user's** mailbox —
+they answer `401` until device-code sign-in completes.
+
+---
+
+## `GET /sync/read-status`
+
+The workhorse. Asks Graph "what changed in this folder since my cursor?", emits
+the changes, and advances the cursor.
+
+The **first** call has no cursor, so it backfills the entire folder — an Inbox
+with 4,700 messages is 47 pages of 100. Every call after that is incremental and
+usually near-empty.
+
+| Param | Default | Meaning |
+| ----- | ------- | ------- |
+| `folder` | `inbox` | Well-known name (`inbox`, `sentitems`, …) or folder id. Graph delta is **folder-scoped** — there is no all-mail delta |
+| `since` | – | ISO8601 lower bound, **initial sync only** (`receivedDateTime ge …`). The way to keep a first backfill small |
+| `reset` | `false` | Discard the saved cursor and start a fresh baseline |
+| `max_pages` | `10` | Cap on Graph pages (100 msgs each) fetched **per call** |
+| `limit` | `10` | Cap on messages returned **in this response** |
+
+`max_pages` and `limit` are independent and easy to confuse:
+
+- **`max_pages` bounds the work.** Hit the cap and the call returns
+  `complete: false`, having saved its position; the next call resumes exactly
+  where it stopped. No changes are skipped, and no cursor is written until the
+  backfill genuinely finishes.
+- **`limit` only trims the JSON.** It has no effect on how much is fetched.
+  `count` stays the true total, and the untruncated set is on
+  `/sync/read-status/changes`.
+
+```jsonc
+{
+  "synced_at": "2026-08-07T10:15:00Z",
+  "folder": "inbox",
+  "count": 1000,            // changed messages this call actually fetched
+  "removed_count": 0,       // deleted / moved out of the folder
+  "initial_sync": true,     // this round is part of the first backfill
+  "complete": false,        // hit max_pages — call again to continue
+  "pages": 10,              // Graph pages fetched by this call
+  "truncated": true,        // limit cut the lists below
+  "value":   [ { "id": "AAMk…", "isRead": true,
+                 "lastModifiedDateTime": "2026-08-07T10:14:52Z",
+                 "subject": "Invoice #421" } ],
+  "removed": [ { "id": "AAMk…", "reason": "deleted" } ]
+}
+```
+
+`value` is sorted newest-modified first before `limit` is applied, so a
+truncated response shows the most recent changes rather than an arbitrary slice.
+Only the four `$select` fields above come back — this endpoint is about *status*,
+not content; use `GET /emails/{id}` for bodies.
+
+## `GET /sync/read-status/changes`
+
+Read-only replay of whatever the **last** round produced. No Graph call, cursor
+untouched, safe to hit repeatedly.
+
+Two reasons it exists:
+
+1. It holds the **untruncated** lists — this is how you get the other 990 items
+   when `limit` trimmed the response.
+2. It's the only way to collect what the **background watcher** found, since the
+   watcher has no caller to return to.
+
+`404` until some sync has run. One buffer, last-writer-wins: the next round
+overwrites it, so with the watcher running you must read it faster than
+`interval` or you will miss rounds.
+
+## `GET /sync/read-status/message/{message_id}`
+
+One message, one record — a point lookup rather than a batch:
+
+```jsonc
+{ "id": "AAMk…", "isRead": true,
+  "lastModifiedDateTime": "2026-08-07T10:14:52Z", "subject": "Invoice #421" }
+```
+
+Identical shape to an entry in a sync `value` list, so both parse with the same
+code. What makes it different from the endpoints above:
+
+- **Cursor-free.** Touches no delta cursor, no cached state, and advances
+  nothing. Call it as often as you like without affecting a sync in progress.
+- **Live.** Reports the mailbox *now*, straight from Graph — not what the last
+  round happened to capture. That makes it the right tool for re-checking one
+  message ("has this been read yet?") and for confirming a status after the fact.
+- **Any id.** Works whether or not the message appeared in a sync, and whatever
+  folder it lives in.
+
+It costs one Graph call per message, so it's a lookup, not a substitute for
+delta — walking a mailbox with it would be far slower than a single sync round.
+
+```bash
+curl -H "$A" "$B/sync/read-status/message/AAMkAGI2TG93..."
+```
+
+URL-encode the id. Ids containing `/`, `+`, or `=` are handled (the route uses a
+`:path` converter), so an already-encoded `%2F` works too. Unknown or deleted
+ids surface Graph's own `404 ErrorItemNotFound`.
+
+## `GET /sync/read-status/status`
+
+Health check for the whole subsystem.
+
+| Field | Meaning |
+| ----- | ------- |
+| `watching` / `interval` | Is the poller thread alive, and at what period |
+| `folder` | Folder the cursor belongs to |
+| `last_sync_at` | Timestamp of the most recent round |
+| `last_change_count` / `last_removed_count` | Size of that round |
+| `has_delta_link` | A real cursor exists ⇒ running incrementally |
+| `backfill_in_progress` | Paused mid-backfill at the page cap ⇒ more rounds to go |
+| `last_error` | Last Graph failure from the background thread, else `null` |
+
+`has_delta_link: false` + `backfill_in_progress: true` is the normal state
+*during* a long first sync.
+
+## `POST /sync/read-status/watch`
+
+Starts a daemon thread that runs the same sync every `interval` seconds and
+writes each change to stdout.
+

+```
+
+- Idempotent — a second POST while running just answers
+  `{"message": "Already watching read-status changes"}`.
+- While a backfill is still incomplete the loop continues immediately instead of
+  sleeping out the interval, so a big first sync finishes in consecutive chunks.
+- Delivery is `_emit_read_status_changes()`, which prints. **That's the hook
+  point** — replace it to push to Slack, a webhook, or a queue.
+
+## `DELETE /sync/read-status/watch`
+
+Signals the thread to stop; `404` if nothing is running. The cursor survives, so
+restarting the watcher resumes from where it left off rather than re-backfilling.
+
+---
+
+## Typical first run
+
+```bash
+export EMAIL_API_TOKEN=...
+A="Authorization: Bearer $EMAIL_API_TOKEN"
+B=http://localhost:5000
+
+curl -X POST -H "$A" $B/auth/start      # sign in once (see README)
+
+# Baseline. Keep calling while "complete": false.
+curl -H "$A" "$B/sync/read-status?since=2026-08-01T00:00:00Z"
+
+# From here on, each call returns only what changed.
+curl -H "$A" "$B/sync/read-status"
+
+# Or hand it to the background poller and read results out of /changes.
+curl -X POST -H "$A" -H "Content-Type: application/json" \
+     -d '{"interval":60,"folder":"inbox"}' $B/sync/read-status/watch
+curl -H "$A" $B/sync/read-status/status
+curl -H "$A" $B/sync/read-status/changes
+
+# Re-check one message any time — no cursor involved.
+curl -H "$A" "$B/sync/read-status/message/AAMkAGI2TG93..."
+```
+
+## Which endpoint do I want?
+
+| You want | Use |
+| -------- | --- |
+| Everything that changed since last time | `GET /sync/read-status` |
+| The full list a round produced (or the watcher's) | `GET /sync/read-status/changes` |
+| The status of **one** message you already have an id for | `GET /sync/read-status/message/{id}` |
+| Continuous tracking without calling in a loop | `POST /sync/read-status/watch` |
+| Whether any of the above is healthy | `GET /sync/read-status/status` |
+
+Rule of thumb: **delta for "what changed", point lookup for "what about this
+one".** Using the lookup in a loop over a mailbox works but costs one Graph call
+per message — a single sync round does the same job in pages of 100.
+
+## How the cursor works
+
+- A finished round returns Graph's **deltaLink**, saved to
+  `.delta_cache.json` (override with `EMAIL_API_DELTA_CACHE`; in Docker it lives
+  on the `/data` volume beside the token cache). Keyed by user + folder — change
+  either and the cache is ignored rather than misapplied.
+- A round stopped by `max_pages` has no deltaLink yet, so it saves Graph's
+  **nextLink** instead. That resume position takes priority over any older
+  deltaLink on the following call, which is what makes a capped backfill safe:
+  the cursor never advances past data you haven't received.
+- Cursors expire. Graph answers `410 Gone`, and the sync automatically falls
+  back to a fresh baseline for that folder.
+- `reset=true` throws the cursor away deliberately — expect a full backfill, and
+  pass `since` with it unless you want the whole history again.
+
+## Limits worth knowing
+
+- **Folder-scoped only.** `/me/messages/delta` is not supported by Graph. Watch
+  another folder by passing `folder=`, but each folder is its own cursor and the
+  disk cache holds one at a time — switching folders forces a re-backfill.
+- **Polling, not push.** Latency floor is the poll `interval`. True push needs a
+  Graph change-notification subscription (public HTTPS endpoint, validation
+  handshake, ~3-day renewals) — and you'd keep delta anyway as the catch-up path
+  for dropped notifications.
+- **Single worker.** Cursor, watcher thread, and the `last_changes` buffer are
+  in-memory per process, so this only behaves with one uvicorn worker (which is
+  what the Docker service runs, for the same reason auth needs it).

+# Email service — write read-status (`PATCH /sync/read-status/...`)
+
+Copy everything below the line into any LLM session (or hand it to whoever owns the
+email microservice) before implementing the write endpoint.
+
+---
+
+You are extending the **email microservice** that already exposes the read-status
+delta and point-lookup APIs documented in `Sync_read.md`. Implement a **write**
+path that marks a message read (or unread) in the signed-in user's Outlook mailbox
+via Microsoft Graph. Mirror the existing `/sync/read-status/*` style exactly —
+same bearer auth, same `:path` id handling, same response shape.
+
+## Why we need this
+
+The HR-ATS inbox app learns that a user opened a message before Outlook does.
+Today that signal dies in our database: we have no Graph write permission and the
+email service exposes no write endpoint. Without this PATCH, local mark-read and
+Outlook drift permanently (and a later delta can even revert our flag).
+
+## Requested contract
+
+Mirror the existing read endpoints so both parse with one code path:
+
+```
+PATCH /sync/read-status/message/{id}
+Authorization: Bearer <api token>
+Content-Type: application/json
+
+{ "isRead": true }
+```
+
+**200 response** — identical shape to `GET /sync/read-status/message/{id}`:
+
+```jsonc
+{
+  "id": "AAMk…",
+  "isRead": true,
+  "lastModifiedDateTime": "2026-08-07T10:14:52Z",
+  "subject": "Invoice #421"
+}
+```
+
+Same `:path` converter for Graph ids that contain `/`, `+`, or `=`. Same bearer
+auth as every other `/sync/*` route. Answer `401` until device-code sign-in
+completes.
+
+## Required behaviour
+
+- **Idempotent.** Re-PATCHing `isRead: true` when already true is a no-op `200`
+  with the current record.
+- **Must not advance or disturb the delta cursor.** This is a point write, not a
+  sync round. Cursor, watcher, and `/changes` buffer stay untouched.
+- **404 `ErrorItemNotFound`** for unknown or deleted ids (same as the GET).
+- **403 surfaced distinctly** if the Graph scope is missing, so callers can tell
+  "not permitted" from "not found".
+
+## Graph scope prerequisite
+
+Needs `Mail.ReadWrite`. The service currently signs in read-only. Treat upgrading
+the consent / device-code scopes as an explicit product decision before shipping
+the route — not an implementation footnote.
+
+## Optional batch form
+
+For bulk reconcile without N round-trips:
+
+```
+PATCH /sync/read-status/messages
+{ "ids": ["AAMk…", "AAMk…"], "isRead": true }
+```
+
+Return a list of the same per-message records (or per-id errors). Nice-to-have;
+the single-id PATCH is the hard requirement.
+
+## What the caller will do with it
+
+HR-ATS will enqueue one Taskiq task per human mark-read, retried via existing
+smart-retry middleware. Expected volume is low (opens, not sweeps). After this
+lands we will stop treating local-only mark-read as a known divergence.
+
+## Out of scope for this request
+
+- Changing the delta `/sync/read-status` contract
+- Push / Graph change-notification subscriptions
+- Writing any field other than `isRead`

+# HR-ATS Backend LLM Context Prompt
+
+Copy everything below the line into any LLM session before asking it to write or edit backend code.
+
+---
+
+You are coding inside **HR-ATS-Portal** (`backend/`). You must follow this house style **exactly**. Mirror neighboring files. Do not invent alternate patterns, layers, or response shapes. Prefer matching existing code over “cleaner” industry defaults.
+
+## Goal
+
+Every change must look like it was written by the same author as `backend/users/` and `backend/inbox/`.
+
+## Package layout (every domain)
+
+```
+backend/<domain>/
+  app.py          # routes only — HTTP in/out
+  views.py        # service class — business logic
+  models.py       # SQLModel table + classmethod DB accessors
+  serializers.py  # hand-rolled dict builders (no Pydantic response models)
+  plugins.py      # pure helpers (hash, JWT, clean payload) — NO FastAPI imports
+  permissions.py  # OAuth2 scheme + Depends aliases (auth domains only)
+```
+
+- Bare `router = APIRouter()`; mount in `main.py` with `app.include_router(...)`.
+- No package `__init__.py`. Run from `backend/` so imports are top-level (`users.app`, `db_setup`).
+- Non-DB config: module-level `load_dotenv()` + `os.getenv(...)`. Do **not** extend `db_setup.Settings` for app secrets.
+
+## Layer duties (non-negotiable)
+
+| Layer | Owns | Must NOT do |
+|---|---|---|
+| `app.py` | Routes, inline request Pydantic models, `JSONResponse`, HTTP token envelope via serializers, inject `session` / `CurrentUser` | Business rules, SQL, JWT crypto beyond calling plugin functions |
+| `views.py` | Business checks, call models, raise `HTTPException`, return ORM user (auth) or serialized dict (CRUD) | Call `serialize_token` or build login HTTP payloads |
+| `models.py` | Fields, queries, inserts/updates/soft-delete, `selectinload` when needed | HTTPException, FastAPI, serializers |
+| `serializers.py` | `serialize_*` → plain `dict` | DB, Depends |
+| `plugins.py` | Pure helpers; raise library errors (`jwt.*`) | Import FastAPI / raise HTTPException |
+| `permissions.py` | `OAuth2PasswordBearer`, `get_current_user`, `CurrentUser` alias, `require_permission` | Route handlers |
+
+## Exact route pattern (`app.py`)
+
+- Paths are verb-in-path: `/users/create`, `/users/fetch`, `/users/login` — **not** `/auth/token`, not REST-resource-only.
+- Standard wrapper on every handler:
+
+```python
+try:
+    service=User(session=session)
+    data=await service.some_method(...)
+    return JSONResponse(content={"data":data,"status_code":200})
+except HTTPException:
+    raise
+except Exception as e:
+    raise HTTPException(status_code=500,detail=str(e))
+```
+
+- List: `{"data":items,"total":total,"status_code":200}`. By id: include `"total":1`.
+- Login / refresh — **service returns ORM user**; route mints tokens and serializes:
+
+```python
+user=await service.authenticate_user(form_data.username,form_data.password)
+tokens=serialize_token(create_access_token(user),create_refresh_token(user),user)
+return JSONResponse(content={**tokens,"status_code":200})
+```
+
+- Request body models stay **inline in `app.py`** (`UserCreate`, `UserUpdate`, `TokenRefresh`). Never move them into `serializers.py`.
+- Use `session: AsyncSession = Depends(get_session)` by default. Use `Annotated` only when required (`OAuth2PasswordRequestForm`, `CurrentUser` before other defaulted params).
+- Preserve tight local spacing: `service=User(session=session)`, `detail=str(e)`. Do not pretty-reformat unrelated code.
+
+## Exact service pattern (`views.py`)
+
+```python
+class User:
+    def __init__(self,session:AsyncSession):
+        self.session=session
+
+    async def create_user(self,payload):
+        ...
+        return serialize_user(user)
+```
+
+- Leave service method parameters untyped (match existing).
+- Raise `HTTPException(status_code=...,detail="...")` for domain errors.
+- `authenticate_user` / `refresh_access_token` return the **Users ORM instance only**.
+- If you loaded via an accessor that does not `selectinload(role)`, re-fetch with `get_user_by_id` before serialization that touches `user.role`. (`get_user_by_email` and `get_user_by_id` both eager-load `role` today.)
+
+## Exact model pattern (`models.py`)
+
+- SQLModel `table=True`; accessors as `@classmethod async def`.
+- Soft delete sets `is_deleted=True` and `is_active=False`.
+- `selectinload` relations that serializers read.
+- Commits happen inside write accessors (existing convention).
+
+## Serializers
+
+- Hand-built dicts only. `str(uuid)`, `.isoformat()` for datetimes. Never include `password`.
+- Token response: OAuth2 fields at **root** (`access_token`, `refresh_token`, `token_type`, `expires_in`); user record under `data`.
+
+## Auth (when touching users auth)
+
+- PyJWT access + refresh with a `type` claim; `decode_token(..., expected_type=...)` rejects mismatches.
+- Protect `/users/*` with `current_user: CurrentUser` except `/users/login` and `/users/refresh`. Prefer `Depends(require_permission(...))` on mutating/list routes that need a specific tag; keep `/users/me` on plain `CurrentUser` so users can discover a missing-role state.
+- `get_current_user`: decode access → DB by `sub` → reject missing/deleted/inactive → return `serialize_user(user, with_permissions=True)`.
+- Login: `OAuth2PasswordRequestForm` (username = email). `tokenUrl="users/login"` (no leading slash).
+- JWT `iat`/`exp` use `datetime.now(timezone.utc)` only — never naive `datetime.now()`.
+
+## Dependencies / env
+
+- Add pins to `backend/requirements.txt` under banner comments with a trailing `# why` comment.
+- Put secrets in `backend/.env`; keep key names in `backend/.env.example`.
+
+## Hard bans
+
+1. No repository / use-case / DTO layers beyond inline request models.
+2. No Pydantic response models; no alternate envelopes; no `/api/v1` prefix.
+3. No `serialize_token` inside `views.py`.
+4. No FastAPI imports in `plugins.py`.
+5. No drive-by refactors, renames, or whole-file reformats.
+6. RBAC exists in `users/permissions.py`; do not invent a second scheme.
+7. Do not edit unrelated domains (`inbox/` vs `users/`) unless asked.
+8. Do not add `__init__.py` to make packages.
+
+## Workflow when adding an endpoint
+
+1. Model accessor (if DB).
+2. Service method in `views.py`.
+3. `serialize_*` if new shape.
+4. Route in `app.py` with the standard try/except + `JSONResponse`.
+5. Add `current_user: CurrentUser` or `Depends(require_permission(...))` if the route is protected.
+
+Before finishing, re-read the touched files and confirm they still match a sibling file’s structure, naming, spacing, and response shape.

+# HR-ATS-Portal — Backend
+
+FastAPI service behind **TalentFlow**, an HR / Applicant-Tracking portal. It pulls candidate
+applications out of a mailbox, decodes CV attachments, runs an LLM agent to match each CV
+against live job posts, publishes job ads to social channels through Buffer, and serves the
+whole thing to the frontend behind JWT auth and a database-driven RBAC model.
+
+Everything in this document describes `backend/` only.

+
+**The application flow, end to end:**
+
+1. `GET /email/fetch` pulls messages from the external Email API, decodes PDF/DOC/DOCX
+   attachments to `inbox/decoded_attachments/`, and upserts them into `inbox_messages`.
+2. When a message carries an attachment, the sender is linked to a `users` row — created with
+   the `candidate` role if new — through the `inbox` join table.
+3. Any message with a stored attachment and no match result yet is enqueued onto Redis as an
+   `inbox.match_message` task.
+4. The worker extracts the résumé text, hands it plus the active job posts to the LangGraph
+   agent, and writes `suggested_job_post_ids`, `match_summary`, `match_reasoning` and
+   `experience` back onto the row.
+5. New candidate accounts land inactive and are mailed a confirmation link; the link is what
+   flips `is_active`.
+6. A cron task sweeps Outlook read-status deltas back onto `inbox_messages.message_read`.
+7. Recruiters read all of it through `/inbox/all-applications` and publish new roles with
+   `POST /job/post-job`, which renders the ad copy and pushes it to Buffer.

+
+There are **no `__init__.py` files**. The service is run from `backend/`, so imports are
+top-level (`from users.app import router`, `from db_setup import get_session`).
+
+---
+
+## House style — what lives in which file
+
+Every domain package follows the same six-file shape. This is enforced by convention, and
+`LLM_CONTEXT_PROMPT.md` is the canonical statement of it.
+
+| File | Owns | Must not do |
+|---|---|---|
+| `app.py` | Routes, inline request models, `JSONResponse`, dependency injection | Business rules, SQL |
+| `views.py` | Business checks, calls models, raises `HTTPException` | Build login token envelopes |
+| `models.py` | SQLModel table + `@classmethod async def` accessors | Import FastAPI, raise `HTTPException` |
+| `serializers.py` | Hand-built `dict` builders (`serialize_*`) | Touch the DB or `Depends` |
+| `plugins.py` | Pure helpers — hashing, JWT, HTTP calls to third parties | Import FastAPI |
+| `permissions.py` | Bearer schemes and `Depends` aliases (auth domains only) | Hold route handlers |
+
+Additional rules that matter when you edit this code:
+
+- Request bodies are Pydantic models declared **inline in `app.py`**, never in `serializers.py`.
+- There are **no Pydantic response models** — responses are hand-built dicts.
+- Route paths are verb-in-path (`/users/create`, `/users/fetch`), not REST-resource-only, and
+  there is no `/api/v1` prefix.
+- Non-DB config is module-level `load_dotenv()` + `os.getenv(...)`. Only database settings go
+  through `db_setup.Settings`.
+
+---
+
+## Domains
+
+### `users/`
+Signup, login, refresh, CRUD, role assignment, and the RBAC machinery every other domain
+depends on. `users/permissions.py` defines the full `PermissionTag` vocabulary (13 modules ×
+8 actions = 104 tags) and the `require_permission(...)` dependency. A startup assertion
+(`_assert_vocabulary_complete`) fails loudly if the tag list ever drifts from
+`PermissionModule × PermissionAction`.
+
+Signup always assigns the `candidate` role, creates the account **inactive**, and sends a
+confirmation email. Login rejects unconfirmed accounts.
+
+### `role/`
+Three-level permission model: `permission_tags` (atomic `module.action` rows) →
+`permissions` (named bundles holding a JSONB array of tag ids) → `roles` (holding a JSONB
+array of bundle ids). `Roles.resolve_tags()` walks that chain and returns a flat tuple of tag
+names; dangling or inactive ids simply contribute nothing rather than erroring.
+
+Eight system roles are seeded: `system_administrator`, `hr_administrator`, `recruiter`,
+`hiring_manager`, `department_head`, `interviewer`, `ceo`, `candidate`.
+
+### `inbox/`
+The heart of the ingestion pipeline.
+
+- `views.py::Email` talks to the external Email API, decodes attachments, upserts messages,
+  and enqueues matching work.
+- `models.py` holds `Inbox_Messages` (the mail rows plus all agent output columns),
+  `Inbox_Alerts`, and `Inbox` — the join table linking a message to the candidate `Users` row
+  it came from. `_link_sender` creates the candidate account on first contact, skipping
+  `noreply@`-style senders.
+- `file_decoder.py` turns Graph `contentBytes` into real PDF / DOCX / DOC files, validating
+  magic bytes for each format and stripping path traversal from filenames.
+- `plugins.py` resolves attachment paths (handling Windows paths written by the host API but
+  read from a Linux worker), extracts résumé text, and calls the read-status sync endpoints.
+- `tasks.py` / `sync_tasks.py` are the two Taskiq tasks.
+
+### `job/`
+Two sub-domains behind one router:
+
+- **`job_post/`** — renders LinkedIn-shaped ad copy from a structured payload, resolves the
+  Buffer channel (by explicit id, by platform alias, or by the configured default), creates
+  the post over Buffer's GraphQL API, and records the mapped status. A queued post is recorded
+  as `scheduled`, not `published`; only Buffer reporting `sent` promotes it.
+- **`candidate/`** — `FileRead` extracts text from an uploaded PDF (`pypdf`), and
+  `match_inbox_cv` force-requeues an existing inbox message for matching. `CandidateView`
+  reads the candidate profile through the `inbox` join.
+
+### `notifications/` and `forget_password/`
+Two parallel token flows, deliberately kept separate so each owns its own mail copy and env
+reads:
+
+- **Confirmation** — a 32-byte url-safe secret, bcrypt-hashed in
+  `email_confirmation_tokens`; the link carries `<row_id>.<secret>` because a bcrypt hash
+  cannot be looked up. Replays (mail scanners, back button) are handled idempotently.
+- **Password reset** — a short code mailed to the user, bcrypt-hashed in
+  `password_reset_codes`, with a resend cooldown and a max-attempts cap. Verifying the code
+  mints a `type=reset` JWT carrying the code row id (`crid`), which is the only thing that
+  authorises the new-password call.
+
+### `agent/`
+LangGraph state machine — see [The matching agent](#the-matching-agent).
+
+### `taskiq_management/`
+Broker, scheduler, DLQ middleware, and a `ping` smoke task.
+
+---
+
+## Data model
+
+All tables live in the `app` schema (`DB_DEFAULT_SCHEMA`), with a shared naming convention for
+indexes, constraints and foreign keys. `SQLModel.metadata` is pointed at `Base.metadata` in
+`db_setup.py` so SQLModel and DeclarativeBase share one registry and Alembic sees everything.
+
+| Table | Key columns | Notes |
+|---|---|---|
+| `users` | `id` (uuid PK), `email` (unique), `role_id` → `roles.id`, `password`, `is_active`, `is_deleted` | Soft delete. `role` is `selectin`-loaded; lazy loads would raise `MissingGreenlet` under asyncio |
+| `roles` | `id`, `role_name` (unique), `permissions` (JSONB int[]), `is_system` | |
+| `permissions` | `id`, `name` (unique), `permission_tags` (JSONB int[]) | Named bundles |
+| `permission_tags` | `id`, `tag_name` (unique), `module`, `action` | Unique on (`module`, `action`) |
+| `inbox_messages` | `id` (uuid), `message_id` (upstream id, unique), `full_email_response` (JSONB), subject/body/from/to/cc/bcc, `message_read`, `attachment`, `file_name`, `file_path`, `application_status`, `resume_text`, `experience`, `suggested_job_post_ids` (JSONB), `match_summary`, `match_reasoning`, `match_status`, `match_error`, `matched_at` | One row per mail; agent output lands here |
+| `inbox` | `id`, `user_id` → `users.id`, `message_id` → `inbox_messages.id`, `alert_id` | Join table linking a candidate to a message |
+| `inbox_alerts` | `id`, `alert_sender_name`, `alert_sender_email`, `is_read` | |
+| `job_posts` | `id` (uuid), `title`, `platform`, `channel_id`, `post_text`, `requirements`/`optional_skills` (JSON), `status`, `buffer_post_id`, `buffer_external_link`, `buffer_sent_at`, `buffer_error`, `created_by` → `users.id` | |
+| `password_reset_codes` | `id`, `email`, `code_hash`, `expires_at`, `attempts`, `is_used`, `verified_at` | |
+| `email_confirmation_tokens` | `id`, `user_id`, `email`, `token_hash`, `expires_at`, `is_used`, `confirmed_at` | |
+
+`application_status` is a `str` enum: `PROCESS`, `PENDING`, `APPROVED`, `REJECTED`, `ONHOLD`,
+`CLOSED`.
+
+`match_status` is free-form text written by the worker: `processing`, `matched`, `skipped`,
+`no_text`, `failed`, `dlq`.

+| POST | `/inbox/{record_id}/match` | `inbox.edit` | Force a re-match of one message |

+| GET | `/inbox/{record_id}/read-status` | `inbox.edit` | Re-pull read status from upstream for one message |
+
+### Jobs and candidates — `job/app.py`
+
+| Method | Path | Required tag | Purpose |
+|---|---|---|---|
+| GET | `/jobs/alias` | public | Accepted platform shorthands (`fb`, `ig`, `li`, `x`, …) |
+| POST | `/job/post-job` | `job_board.create` | Render the ad, create the Buffer post, persist the result |
+| GET | `/job/buffer/channels` | `job_board.view` | Connected Buffer channels across all organizations |
+| POST | `/candidate/cv_upload` | `candidates.create` | Upload a PDF; extract email, persist like an emailed CV, enqueue matching on the CV stream |
+| POST | `/candidate/inbox-match?inbox_message_id=` | `candidates.edit` | Queue a forced re-match for a stored message |
+| GET | `/candidate/fetch?user_id=` | `candidates.view` | Candidate profile via the `inbox` join |
+
+`POST /job/post-job` takes `mode` ∈ `addToQueue` | `shareNow` | `customScheduled`; the
+`customScheduled` mode requires `scheduler_date` (and optionally `scheduler_time`), which the
+route combines into a UTC `due_at`.
+
+---
+
+## Authentication and RBAC
+
+**Tokens.** PyJWT, HS256, with a `type` claim that `decode_token(..., expected_type=...)`
+rejects on mismatch. Three types:
+
+| Type | Lifetime (default) | Extra claims |
+|---|---|---|
+| `access` | 30 min | `email`, `role_id` |
+| `refresh` | 7 days | — |
+| `reset` | 10 min | `crid` (reset-code row id) |
+
+`iat` / `exp` are always timezone-aware UTC. Every token carries a `jti`.
+
+**Login response** puts the OAuth2 fields at the root so Swagger's Authorize button can read
+them:
+
+```json
+{
+  "access_token": "...",
+  "refresh_token": "...",
+  "token_type": "bearer",
+  "expires_in": 1800,
+  "data": { "id": "...", "email": "...", "role_id": 3, "role_name": "recruiter", "...": "..." },
+  "status_code": 200
+}
+```
+
+**Passwords** use `bcrypt` directly rather than `passlib` — passlib 1.7.4 reads
+`bcrypt.__about__.__version__`, which bcrypt dropped in 4.1, and the failed probe makes it
+reject every password as over 72 bytes. Input is truncated to 72 bytes on a character
+boundary before hashing.
+
+**Authorization.** `get_current_user` decodes the access token, loads the user by `sub`,
+rejects missing / deleted / inactive accounts, resolves the role's tags, and returns a
+serialized user dict with a `permissions` list. `require_permission(*tags, require_all=True)`
+is the dependency that guards routes; a user with no role assigned gets a 403 before any tag
+check runs.
+
+Role assignment is additionally guarded in `users/views.py`: you cannot grant a role holding
+permissions you do not yourself hold.
+
+---
+
+## Background jobs
+
+Taskiq over **Redis Streams**, with a result backend and a Redis-backed schedule source.
+
+**Middleware order matters** — `DeadLetterMiddleware` sits before `SmartRetryMiddleware` so a
+`PermanentTaskError` can set `retry_on_error=False` before retry logic runs.
+
+| Task | Trigger | What it does |
+|---|---|---|
+| `inbox.match_message` | enqueued by `/email/fetch`, `/inbox/{id}/match`, `/candidate/inbox-match` onto the `inbox` stream | Extract résumé text → run the agent → write match results |
+| `inbox.match_message` (CV broker) | enqueued by `/candidate/cv_upload` onto the `cv_upload` stream | Same matcher as above; isolated so uploads never sit behind `/email/fetch` backlog |
+| `inbox.sync_read_status` | cron, `EMAIL_SYNC_CRON` (default every minute) | Pull read-status deltas from the Email API and apply them |
+| `ping` | manual | Framework smoke test |
+
+**Retries.** `SmartRetryMiddleware` with jitter and exponential delay, `TASKIQ_MAX_RETRIES`
+attempts, capped at `TASKIQ_MAX_DELAY`. Raising `PermanentTaskError` (missing record, no
+attachment, blank `record_id`) skips retries entirely.
+
+**Dead letter queue.** Exhausted or permanently-failed tasks are written to the
+`taskiq:dlq` Redis stream as a JSON payload. For `inbox.match_message` specifically, the
+middleware also stamps `match_status="dlq"` on the row so the failure is visible in the UI
+rather than only in Redis.
+
+**The read-status latch.** `apply_read_status` only ever applies `false → true`. Nothing
+pushes local reads back to Outlook, so upstream keeps reporting `isRead=false`; without the
+latch the every-minute sweep would un-read a mail the user just opened. The trade-off is that
+un-reading a mail in Outlook no longer propagates here. `sync_read_status` holds a Redis lock
+(`inbox:sync_read_status:lock`, 300s TTL) so overlapping cron ticks cannot double-run, and
+pages at most 10 rounds per tick.
+
+---
+
+## The matching agent
+
+A small LangGraph `StateGraph` over an `AgentState` TypedDict.
+
+```
+START → prepare → (conditional) → match_jobs → END
+                └→ END        (when resume_text or job_posts is empty)
+```
+
+- **`prepare_context`** trims the subject and résumé text and normalizes the job posts down to
+  the fields the model needs. Empty résumé text or no active posts short-circuits to
+  `status="skipped"`.
+- **`match_jobs`** calls `llm_call(prompt(), user_prompt(state), json_mode=True)` and parses
+  the response.
+
+The parser (`agent/decorators.py::parse_match_response`) is deliberately strict: a suggested
+id must be present in the posts that were actually sent, must be a valid UUID, and duplicates
+are dropped. The model cannot invent a job post. `reasoning` returned as a list is joined into
+a string; non-string fields fall back to `""`.
+
+The graph is compiled once per process (`init_agent()` from the FastAPI lifespan, or lazily on
+first use inside the worker) and the OpenAI client is created lazily and closed on shutdown.
+
+Startup is **fault-tolerant**: if the broker or the LLM/agent fails to initialize, `main.py`
+logs a warning and the API still serves. Only the database is a hard requirement.
+
+---
+
+## External integrations
+
+| Service | Used by | Contract |
+|---|---|---|
+| **Email API** (a Microsoft Graph proxy) | `inbox/` | `GET {EMAIL_URL}/emails`, `GET {EMAIL_URL}/emails/{id}`, `GET {EMAIL_URL}/sync/read-status`, `GET {EMAIL_URL}/sync/read-status/message/{id}` — Bearer `EMAIL_API_TOKEN` |
+| **Teams Mail API** | `notifications/`, `forget_password/` | multipart POST to `TEAMS_MAIL_API_URL`; success is HTTP **202**, anything else raises |
+| **Buffer** | `job/job_post/` | GraphQL against `BUFFER_API_URL` — `createPost` mutation, `account { organizations }` and `channels` queries |
+| **OpenAI** | `agent/`, `llm_setup.py` | Chat Completions with `response_format: json_object` |
+
+Attachments are written to `backend/inbox/decoded_attachments/`. In Docker this directory is
+bind-mounted into the worker so both processes see the same files.
+
+---
+
+## Configuration
+
+Copy `.env.example` to `.env` and fill it in. `.env` is git-ignored; `.env.example` is not.
+`db_setup.Settings` reads `backend/.env` or the repo-root `.env`; every other module reads its
+own keys with `os.getenv`.

+
+---
+
+## Running locally
+
+**Prerequisites:** Python 3.12, PostgreSQL, Redis.
+
+```bash
+cd backend
+
+python -m venv .venv
+source .venv/bin/activate          # Windows: .venv\Scripts\activate
+pip install -r requirements.txt
+
+cp .env.example .env               # then fill it in
+```
+
+All commands must be run from `backend/` — the import paths depend on it.
+
+**API:**
+
+```bash
+uvicorn main:app --reload --port 8000
+```
+
+Startup connects to Postgres (retrying with backoff), creates the configured schemas, runs
+migrations to head, then starts the broker, the OpenAI client and the agent graph. Broker and
+LLM failures are logged and skipped; the API still comes up.
+
+**Worker** (needs Redis):
+
+```bash
+taskiq worker taskiq_management.broker_setup:broker \
+  inbox.tasks inbox.sync_tasks taskiq_management.tasks
+```
+
+**CV-upload worker** (isolated stream for manual uploads):
+
+```bash
+taskiq worker taskiq_management.cv_broker_setup:cv_broker inbox.cv_tasks
+```
+
+**Scheduler** (cron ticks for `inbox.sync_read_status`):
+
+```bash
+taskiq scheduler taskiq_management.broker_setup:scheduler inbox.sync_tasks
+```
+
+**CV-upload scheduler** (retries for the CV stream):
+
+```bash
+taskiq scheduler taskiq_management.cv_broker_setup:cv_scheduler inbox.cv_tasks
+```
+
+Docs: <http://localhost:8000/docs>
+

+
+## Database migrations
+
+`alembic_setup.py` wraps Alembic so the plain `alembic` CLI and the app's own
+migrate-on-startup share one configuration. It scaffolds `alembic.ini`, `migrations/env.py`
+and `script.py.mako` on first use and never overwrites them. Model modules are discovered
+automatically — every `<package>/models.py` under `backend/` is imported before the metadata is
+diffed.
+
+```bash
+python alembic_setup.py migrate            # upgrade to head, then autogenerate any drift
+python alembic_setup.py revision -m "add x" # write a revision if the models have drifted
+python alembic_setup.py upgrade -r head
+python alembic_setup.py downgrade -r -1
+python alembic_setup.py current
+python alembic_setup.py head
+```
+
+Migrations run under a Postgres advisory lock, so several workers booting at once cannot
+migrate concurrently. Empty revisions are suppressed. Alembic's own `alembic_version` table is
+excluded from autogenerate, as is anything outside the configured schemas.
+
+The module is named `alembic_setup` rather than `alembic` because `backend/` is on `sys.path`
+and a module called `alembic.py` would shadow the installed package.
+
+---
+
+## Docker
+
+The repo-root `docker-compose.yml` runs Redis plus the four Taskiq processes (inbox
+worker/scheduler and CV-upload worker/scheduler); the API itself is expected to run on the
+host (the compose file points the containers at `host.docker.internal` for the database).
+
+```bash
+docker compose up -d          # from the repo root
+docker compose logs -f taskiq-worker
+docker compose logs -f taskiq-cv-worker
+```
+
+`backend/Dockerfile` builds a `python:3.12-slim` image whose default command is the Taskiq
+worker. `backend/inbox/decoded_attachments` is bind-mounted so the worker can read the
+attachments the API wrote.
+
+---
+
+## Response conventions
+
+Every handler wraps its body in the same try/except:
+
+```python
+try:
+    service=Email(session=session)
+    data=await service.some_method(...)
+    return JSONResponse(content={"data":data,"status_code":200})
+except HTTPException:
+    raise
+except Exception as e:
+    raise HTTPException(status_code=500,detail=str(e))
+```
+
+| Shape | Response |
+|---|---|
+| List | `{"data": [...], "total": <n>, "status_code": 200}` |
+| Single record | `{"data": {...}, "total": 1, "status_code": 200}` |
+| Login / refresh | OAuth2 fields at the root, user under `data` |
+| Error | FastAPI's `{"detail": "..."}` with the real status code |
+
+Serializers always `str()` UUIDs, `.isoformat()` datetimes, and never emit `password`.
+
+---
+
+## Known gaps and gotchas
+
+- **`DB_PORT` must be set.** `db_setup.Settings` evaluates `int(os.getenv("DB_PORT"))` at class
+  definition time, so a missing value raises `TypeError` on import rather than a friendly
+  config error.
+- **CORS is fully open** (`allow_origins=["*"]` with credentials). Fine for development, needs
+  tightening before production.
+- **`/email/fetch` and `/inbox/fetch` carry no permission guard.** `/email/fetch` authenticates
+  only against the upstream Email API token.
+- **`.doc` / `.docx` résumés are decoded and stored but not parsed.** `extract_resume_text`
+  handles PDFs only and reports `no PDF attachment to extract` for the rest.
+- **`serialize_application` returns `null` for `ats_score`, `phone`, `recruiter` and
+  `duplicate`** — `inbox_messages` has no columns for them yet, and `processing` is derived
+  from `message_read` alone, so it is only ever `"Read"` or `"Unread"`.
+- **`Inbox.get_candidate_profile` filters on `cls.user.role_id`**, which is a relationship
+  attribute rather than a joined column; the candidate-profile query needs a join before it
+  behaves as intended.
+- **Attachment paths may be Windows absolutes** written by the host API but read by a Linux
+  worker. `resolve_attachment_path` normalizes separators and falls back to the basename under
+  the mounted `decoded_attachments` directory.
+- **Read status is a one-way latch** — see [Background jobs](#background-jobs).
+- **There is no test suite** in `backend/` at present.
+
+---
+
+## Editing this codebase
+
+Before changing anything here, read [`LLM_CONTEXT_PROMPT.md`](LLM_CONTEXT_PROMPT.md). It states
+the house style in full and is the reference used to keep new code indistinguishable from
+`users/` and `inbox/`. The short version: mirror the neighbouring file, keep the layer duties
+intact, add no new layers, and do not reformat code you did not otherwise need to touch.
+
+Adding an endpoint, in order:
+
+1. Model accessor in `models.py` (if it touches the DB).
+2. Service method in `views.py`.
+3. `serialize_*` in `serializers.py` if the shape is new.
+4. Route in `app.py` with the standard try/except and `JSONResponse`.
+5. `CurrentUser` or `Depends(require_permission(...))` if the route is protected.
