Full AIDLC spec for Month-1 MVP. Scope:

- Next.js 15 + FastAPI + Supabase + LINE + Claude/Gemini adapters
- Every external integration behind a mock/real adapter pair
- Single agent only (no teams), Thai property UX, PDPA-safe defaults
- 12 acceptance criteria + 20 ST-NNN test scenarios

Layout: backend/app/{domain,adapters,routers,services}/ +
web/app/(marketing|auth|app)/. Adapters live behind Protocol classes
so USE_MOCKS=false swaps mock→real adapters with no router change.

Open questions parked for plan phase.

Subject: [PATCH 02/22] feat(T-001): repo scaffold + FastAPI + Next.js shells +
 /health + CI
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Backend (Python 3.11 / FastAPI 0.115 / pydantic v2):
- pyproject.toml with ruff+mypy(strict)+pytest config
- requirements.txt (fastapi, uvicorn, pydantic-settings, jwt, bcrypt, httpx, ...)
- app/main.py factory + CORS + lifespan
- app/config.py (pydantic-settings) — env-driven, mock-first defaults
- app/routers/health.py — GET /health → {"status":"ok"}
- tests/conftest.py + tests/test_health.py (ST-001)
- .env.example

Frontend (Next.js 15 / React 19 / Tailwind v3 / shadcn config):
- package.json, tsconfig.json, next.config.mjs, tailwind.config.ts, postcss
- app/globals.css + design tokens (shadcn variables)
- app/layout.tsx + app/page.tsx (landing shows backend health badge)
- app/api/health/route.ts (proxy → backend)
- lib/api.ts (typed fetch + ApiError + token cache)
- lib/utils.ts (cn helper)
- vitest.config + setup + 1 passing unit test
- components.json (shadcn config), .eslintrc.json, .env.example

CI (GitHub Actions):
- Backend matrix: ruff check, format check, mypy strict, pytest
- Frontend matrix: lint, typecheck, vitest

Toolchains locally verified:
- uvicorn app.main:app → 200 OK on /health and /
- pytest -v: 3/3 passed
- npm run lint: clean
- npm run typecheck: clean
- npm test: 2/2 passed

Subject: [PATCH 03/22] feat(T-002): mock Supabase adapter + migration runner +
 factory
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Backend (Python):
- app/adapters/supabase/base.py — SupabaseAdapter Protocol (query, count, insert, update, delete, get_by_id)
- app/adapters/supabase/_schema.py — Schema/Table/Column dataclasses; DEFAULT_SCHEMA declares all 10 tables (users, teams, properties, leads, messages, appointments, generated_listings, contracts, user_settings, audit_logs) with PG types, NOT NULL, defaults callable (UUID mint, NOW(), role='agent', status='draft', etc.)
- app/adapters/supabase/mock.py — MockSupabaseAdapter: in-memory, insertion-ordered, NOT NULL validation, auto-id, updated_at re-stamp on update, reset() helper
- app/adapters/supabase/real.py — RealSupabaseAdapter: stub, raises NotImplementedError, implements the Protocol so isinstance() succeeds (ST-019-shaped)
- app/adapters/supabase/_factory.py — get_db() selects adapter by Settings(use_real_supabase)
- app/adapters/supabase/__init__.py — public re-exports
- app/adapters/__init__.py
- app/deps.py — DBDep = Annotated[SupabaseAdapter, Depends(get_db_dep)]
- migrations/001_init.sql — canonical Postgres DDL mirroring DB.md
- migrations/__init__.py

Tests (pytest, 22 new tests, total 25/25 passing):
- Schema presence — all 10 expected tables exist (covers AC-01 partial)
- SQL ↔ mock schema parity (table names must match, test fails on drift)
- Round-trip CRUD on users, properties, leads
- Defaults: user.role='agent', property.status='draft', lead.source='line', lead.status='new'
- Auto-id is canonical UUID (36 chars, 4 hyphens)
- NOT NULL enforcement
- update of unknown id → None
- delete of unknown id → False
- count() with and without filters
- Stable insertion-order query (no order_by)
- order_by + desc sorting
- limit + offset pagination
- snapshot stability across fresh adapters
- factory: mock by default, real when USE_REAL_SUPABASE=true

Verified locally:
- pytest -q → 25/25 in 0.03s
- coverage: --cov=app = 91% (real.py only low because stubs are intentional)
- ruff check app/ tests/ → all checks passed
- ruff format app/ tests/ → 18 files left unchanged
- mypy app/ (strict + pydantic plugin) → success, no issues
- uvicorn /health → 200 {"status":"ok"} (no regression)

Subject: [PATCH 05/22] =?UTF-8?q?feat(T-003):=20auth=20=E2=80=94=20signup?=
 =?UTF-8?q?=20/=20login=20/=20LIFF=20/=20/me=20+=20auth=20pages?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Backend (Python, FastAPI, Pydantic v2, bcrypt, PyJWT):
- app/domain/user.py — User + SignupIn + LoginIn + LiffIn + AuthResponse DTOs
- app/services/auth.py — AuthService (signup/login/liff_login/user_from_token),
  hash_password / verify_password (bcrypt), create_access_token / decode_token
  (HS256, jwt_ttl configurable), typed AuthError subclasses (DuplicateEmail 409,
  InvalidCredentials 401, UserNotFound 404) with HTTP mapping
- app/routers/auth.py — POST /api/auth/{signup,login,liff}, GET /api/auth/me
- app/deps.py — get_db_dep already; new AuthServiceDep wired in router
- app/main.py — register auth_router
- app/adapters/supabase/_factory.py — process-singleton mock with thread
  safety; one bug found and fixed during E2E (per-request mock lost state)
- app/adapters/supabase/{_schema.py, ../../migrations/001_init.sql} —
  added password_hash TEXT to users (both mirror each other)
- tests/test_auth.py — 15 tests
  ST-002: signup OK + duplicate → 409
  ST-003: login OK + wrong pwd → 401 + unknown email → 401
  ST-004: LIFF OK + reuse same user + placeholder email
  /me: valid token → 200, no header → 401, malformed → 401, wrong scheme → 401

Frontend (Next.js 15, React 19, Tailwind, ts):
- lib/api.ts — extended: apiGet/apiPost, clearAuthToken, getAuthToken, User type
- lib/auth.ts — login/signup/liffLogin/fetchMe/describeAuthError
- app/(auth)/layout.tsx — card-style auth layout
- app/(auth)/login/page.tsx — email+password + green LINE button
- app/(auth)/signup/page.tsx — full_name+email+password
- app/(app)/dashboard/page.tsx — placeholder that loads /me (real dashboard
  lands in T-011)
- __tests__/auth.test.ts — 7 tests covering wrappers + error mapping

Verified locally:
- pytest: 40/40 (15 new from T-003)
- coverage on app/: 94% (target was 80%)
- ruff + mypy strict: clean
- frontend: lint, typecheck, vitest 9/9
- next build: compiled + 7 routes generated
- end-to-end via curl: signup → JWT → /me returns user across requests

Subject: [PATCH 06/22] feat(T-004): properties CRUD + scoped list page
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Backend:
- app/domain/property.py — PropertyType + PropertyStatus enums; PropertyCreate
  (required), PropertyUpdate (all-optional including status), Property (response)
- app/deps.py — CurrentUserIdDep (bearer token → user id without DB hit) +
  SettingsDep
- app/routers/properties.py — list/create/get/patch/archive scoped to user_id;
  cross-user reads / writes / archives return 404 (not 403) to avoid id probing
- app/main.py — register properties_router
- tests/test_properties.py — 16 tests:
  auth gate (401 without token)
  ST-005: round-trip create + defaults (status='draft', foreign_quota=False)
  list scopes to caller, excludes archived by default
  get / patch / archive flow
  ?status= filter and ?include_archived=true flag
  archive is idempotent
  cross-user isolation: 404 on read, patch, archive; not in list
  payload validation: invalid property_type, negative price, extra fields (422)
  minimal payload accepted

Frontend (Next.js 15):
- lib/types.ts — Property + PropertyCreateInput + PropertyUpdateInput +
  formatTHB (Intl) + propertyTypeLabel (en/th)
- lib/api.ts — added apiPatch/apiDelete/apiPostNoBody
- lib/properties.ts — listProperties/getProperty/createProperty/updateProperty/archiveProperty
- app/(app)/layout.tsx — auth-gated chrome with nav
- app/(app)/properties/page.tsx — client component, redirects if no token,
  loading/error/empty/list states
- components/properties/PropertyCard.tsx — Thai labels + THB format + status pill
- components/properties/PropertyCard.test.tsx — 5 RTL tests (Thai text, fallback,
  status)
- vitest.config.ts — added @vitejs/plugin-react for JSX automatic runtime

Verified locally:
- pytest: 56/56 ✅ (16 new from T-004)
- coverage on app/: 94%
- ruff + mypy strict: clean
- next lint + tsc + build: clean, 8 routes generated
- vitest: 14/14 ✅ (5 new component tests)
- end-to-end via curl: signup → create condo + house → list 2 → archive one → list 1
- 401 without token

 - **Phase**: implementing
 - **Branch**: feat/month-1-mvp
 - **PR**: 1
-- **Last action**: 2026-07-03T07:30:00Z
-- **Next action**: Run /implement T-004 (properties CRUD + list page)
+- **Last action**: 2026-07-03T07:50:00Z
+- **Next action**: Run /implement T-005 (mock storage adapter + property NEW form with image upload)
 - **Notes**:
   - T-001 ✅ scaffold + /health + CI.
-  - T-002 ✅ mock Supabase adapter + Protocol + factory + canonical SQL.
-  - T-003 ✅ auth: signup / login / LIFF / /me, bcrypt + JWT (HS256),
-          /login & /signup pages with LINE LIFF stub button,
-          (app)/dashboard placeholder for auth round-trip.
-    - **Bug found + fixed during E2E:** `MockSupabaseAdapter` was per-request,
-      so /signup-created users vanished by the time /me was called. Resolution:
-      `_factory._get_or_init_mock()` is now a thread-safe process singleton.
-      Tests still work because they use FastAPI `dependency_overrides`.
-    - Schema tiny change: added `password_hash TEXT` to `users` for bcrypt
-      storage. SQL ↔ mock parity test still passes.
-    - 40/40 backend tests, 9/9 frontend tests. Coverage 94% on `app/`.
-  - 9 of 12 tasks remaining. Next: T-004 properties (CRUD needs auth, the
-    first auth-gated router).
+  - T-002 ✅ mock Supabase adapter.
+  - T-003 ✅ auth (signup/login/LIFF/JWT/me) + auth pages.

Subject: [PATCH 07/22] feat(T-005): mock storage adapter + image upload
 endpoint + new property form
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Backend (Python):
- app/adapters/storage/base.py — StorageAdapter Protocol + StoredObject
  DTO + is_allowed_image() allow-list (jpeg/png/webp/gif)
- app/adapters/storage/local_mock.py — disk-backed mock; writes to
  ${var_dir}/uploads/{uuid}{ext}; path-traversal defence (rejects
  '/' / '\\' / '.');
  max 10 MiB per file
- app/adapters/storage/supabase_real.py — stub for MVP (NotImplementedError)
- app/adapters/storage/_factory.py — picks by Settings.use_real_supabase
- app/adapters/storage/__init__.py — public re-exports
- app/deps.py — StorageDep; SettingsDep now reads settings from
  request.app.state (no longer global cache; tests override cleanly)
- app/main.py — register storage_router; app.state.settings set in factory
- app/routers/storage.py —
    POST /api/upload-image (multipart, auth-gated, 415 on bad type,
                              400 on empty/too-big)
    GET  /static/{key} (no auth, 404 on missing/path traversal)
- app/config.py — public_base_url setting (default http://localhost:8000)
- .env.example — PUBLIC_BASE_URL line
- tests/test_storage.py — 14 tests:
    Direct adapter: writes to disk, rejects empty, get round-trip,
    path-traversal blocked, delete idempotent
    HTTP: ST-015 upload returns URL with key; uploaded file served via
    /static/{key}; 401 without auth; 415 on bad extension or MIME;
    accept jpg; 404 on /static/no-such

Frontend (Next.js 15):
- lib/api.ts — apiUpload for FormData (browser sets content-type
  with boundary; Content-Type not forced to JSON for FormData)
- lib/uploads.ts — uploadImage + uploadImages wrappers
- components/forms/ImageUploader.tsx — multi-file picker, generates
  preview thumbnails via URL.createObjectURL, remove button, accepts
  image/* with allow-list
- components/forms/PropertyForm.tsx — client component, all
  property fields (Thai labels, ตร.ม. units, BTS/MRT, foreign quota),
  upload-on-submit flow, error/loading/redirect-to-detail
- app/(app)/properties/new/page.tsx — entry point

Verified locally:
- pytest: 70/70 ✅ (14 new from T-005)
- coverage on app/: 94%
- ruff + mypy strict: clean
- next lint + typecheck + build: clean, 9 routes incl. /properties/new
- vitest: 14/14 ✅
- end-to-end via curl on backend: signup → upload PNG → GET /static/{key}
  returns 200 with PNG bytes

+    - 70/70 backend tests, 14/14 frontend tests, 94% coverage.
+    - Two design decisions worth flagging:
+      1. `StorageAdapter` Protocol uses absolute URLs (from `public_base_url`)
+         so it mirrors Supabase Storage behavior — not `/static/...` relative.
+      2. `SettingsDep` now reads from `request.app.state.settings` so tests
+         pass `Settings(public_base_url='http://testserver')` and the right
+         prefix lands in upload URLs. Side benefit: no global cache collision
+         between test runs.
+    - Autouse fixture `_isolate_app_state` in test_storage.py resets the
+      mock Supabase singleton per test (storage tests don't inject their
+      own DB, they use the singleton).
+  - 7 of 12 tasks remaining. Next is T-006 mock AI (generates Thai
+    listing per property type + platform). T-007 will save those to
+    `generated_listings` and add the detail page that uses PropertyForm's
+    redirect destination.

Subject: [PATCH 08/22] feat(T-006): mock AI adapter + /api/generate-listing +
 ListingPreview
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Backend (Python):
- app/domain/listing.py — Platform enum (4), PropertySummary,
  ListingRequest (forbid extras), GeneratedContent response
- app/adapters/ai/base.py — AiAdapter Protocol + FallbackToNext +
  BadRequest (the two error categories the service distinguishes)
- app/adapters/ai/anthropic_mock.py — deterministic Thai templates
  per (property_type, platform); DDProperty/Livinginsider/Facebook/General;
  includes ตร.ม., ห้องนอน, ห้องน้ำ, ชั้น, โควต้าต่างชาติ; Facebook
  emits 6 hashtags; General is bilingual.
- app/adapters/ai/gemini_mock.py — different model name + tone;
  used as the fallback chain's secondary
- app/adapters/ai/anthropic_real.py, gemini_real.py — stubs raise
  FallbackToNext('not wired in MVP')
- app/adapters/ai/_factory.py — build_ai_chain([primary, secondary])
- app/services/listing_generator.py — orchestrates the chain; raises
  BadRequest immediately; tries next adapter on FallbackToNext OR any
  transient exception; surfaces RuntimeError if all fail
- app/deps.py — AIChainDep
- app/routers/ai.py — POST /api/generate-listing; auth required;
  filters by platforms (default = all 4); 400/422 on bad payload
- app/main.py — register ai_router
- tests/test_ai_generator.py — 13 tests:
    ST-006: condo DDProperty contains คอนโด/ตร.ม./ห้องนอน/BTS Asok
    condo Facebook has ≥ 5 hashtags
    all 4 platforms returned
    ST-007: house General mentions บ้านเดี่ยว or 'house'
    house DDProperty mentions 200 ตร.ม.
    p99 latency < 2s (10 × 4 platforms)
    fallback when primary raises FallbackToNext
    4xx surfaces immediately (no fallback chain)
    fallback when primary raises arbitrary exception
    HTTP: returns 4 platforms, accepts platforms filter, 401 without auth,
    rejects unknown platform (422)

Frontend (Next.js 15):
- lib/types.ts — added Platform/PLATFORM_LABELS/GeneratedContent/
  PropertySummaryForAi
- lib/listings.ts — generateListing() wrapper
- components/forms/ListingPreview.tsx — 4 platform tabs + copy button +
  model badge
- components/forms/ListingPreview.test.tsx — 6 tests
- components/forms/PropertyForm.tsx — added '✨ Generate' button +
  previews ListingPreview when present + generation error handling

Verified locally:
- pytest: 83/83 ✅ (13 new from T-006)
- coverage on app/: 94%
- ruff + mypy strict: clean
- next lint + typecheck + build: clean, 9 routes
- vitest: 20/20 ✅ (6 new from T-006)
- curl E2E: signup → generate 4 platforms → all return Thai text,
  Facebook has 6 hashtags

+- **Last action**: 2026-07-03T08:30:00Z
+- **Next action**: Run /implement T-007 (generated listings persistence + property detail page)
 - **Notes**:
-  - T-001 ✅ scaffold + /health + CI.
-  - T-002 ✅ mock Supabase adapter.
-  - T-003 ✅ auth.
-  - T-004 ✅ properties CRUD.
-  - T-005 ✅ mock storage adapter + upload endpoint + PropertyForm + new page.
-    - 70/70 backend tests, 14/14 frontend tests, 94% coverage.
-    - Two design decisions worth flagging:
-      1. `StorageAdapter` Protocol uses absolute URLs (from `public_base_url`)
-         so it mirrors Supabase Storage behavior — not `/static/...` relative.
-      2. `SettingsDep` now reads from `request.app.state.settings` so tests
-         pass `Settings(public_base_url='http://testserver')` and the right
-         prefix lands in upload URLs. Side benefit: no global cache collision
-         between test runs.
-    - Autouse fixture `_isolate_app_state` in test_storage.py resets the
-      mock Supabase singleton per test (storage tests don't inject their
-      own DB, they use the singleton).
-  - 7 of 12 tasks remaining. Next is T-006 mock AI (generates Thai
-    listing per property type + platform). T-007 will save those to
-    `generated_listings` and add the detail page that uses PropertyForm's
-    redirect destination.
+  - T-001 through T-006 ✅.
+  - T-006 ✅ mock AI listing generator + frontend preview:
+    - 83/83 backend tests, 20/20 frontend tests, 94% coverage.
+    - Mock templates produce Thai text per platform + property type.
+    - Latency: 10 iterations × 4 platforms < 2 s.
+    - Fallback chain proven (primary raises → secondary runs).
+    - 4xx BadRequest surfaces immediately (no fallback).
+  - 6 of 12 tasks remaining. Next: T-007 generated_listings persistence +
+    /properties/[id] detail page with editor + variants. Adds the second
+    DB table beyond properties (and AI-generated content).

Subject: [PATCH 09/22] feat(T-007): generated listings persistence + property
 detail page
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Backend (Python):
- app/domain/listing.py — GeneratedListingCreate + GeneratedListingUpdate
  + GeneratedListing (DB row); strict validation (extra='forbid', title ≥1)
- app/routers/listings.py — POST /api/listings, GET
  /api/listings?property_id=..., PATCH /api/listings/{id}, DELETE
  /api/listings/{id} (204). Cross-user returns 404 (not 403).
- app/main.py — register listings_router
- tests/test_listings.py — 12 tests covering round-trip,
  no-op PATCH, delete idempotency, auth gate, cross-user isolation,
  validation

Frontend (Next.js 15):
- lib/types.ts — SavedListing (extends GeneratedContent with id/created_at
  etc.) + SaveListingInput + UpdateListingInput. Widened property_type
  to string to match backend's permissive PropertySummary.
- lib/listings.ts — added listListingsForProperty, saveListing,
  updateListing, deleteListing
- components/forms/ListingEditor.tsx — tab-style editor per platform
  variant: editable title/description/hashtags/SEO; Save button tracks
  dirty state, shows 'Saved at HH:MM:SS' feedback, falls back to
  'Re-save' after first save
- components/forms/ListingEditor.test.tsx — 6 tests (rendering,
  platform label, dirty/save state)
- components/forms/PropertyForm.tsx — auto-save generated listings on
  property submission (sequential, errors logged not blocking)
- app/(app)/properties/[id]/page.tsx — detail page: property header
  (title, status pill, district/province, key fields, image strip),
  listings grid with one editor per platform variant, generation from
  detail (lazy import saveListing). Has loading/error/empty states.

Verified locally:
- pytest: 95/95 ✅ (12 new from T-007)
- coverage on app/: 94%
- ruff + mypy strict: clean
- next lint + typecheck + build: clean, 11 routes incl.
  /properties/[id] (dynamic)
- vitest: 26/26 ✅ (6 new from T-007)
- curl E2E: signup → property → 2 listings (POST 201) → list 2 →
  PATCH (updated title) → DELETE (204) → 401 without token

 - **Notes**:
-  - T-001 through T-006 ✅.
-  - T-006 ✅ mock AI listing generator + frontend preview:
-    - 83/83 backend tests, 20/20 frontend tests, 94% coverage.
-    - Mock templates produce Thai text per platform + property type.
-    - Latency: 10 iterations × 4 platforms < 2 s.
-    - Fallback chain proven (primary raises → secondary runs).
-    - 4xx BadRequest surfaces immediately (no fallback).
-  - 6 of 12 tasks remaining. Next: T-007 generated_listings persistence +
-    /properties/[id] detail page with editor + variants. Adds the second
-    DB table beyond properties (and AI-generated content).
+  - T-001 through T-007 ✅.
+  - T-007 ✅ listings persistence + detail page:
+    - 95/95 backend tests, 26/26 frontend tests, 94% coverage.
+    - Full close-the-loop: PropertyForm → generate → save property →
+      auto-save 4 listings → redirect to /properties/{id} → editor
+      per platform.
+    - PropertyForm auto-saves generated listings on submit; if save
+      fails, the property still exists (logged to console, surfaced
+      only on the detail page's regeneration button).
+    - Frontend widens `property_type` to `string` since the form holds
+      `""` as the empty value (the backend's PropertySummary accepts
+      any string and routes convert).
+  - 5 of 12 tasks remaining. Next: T-008 — LINE adapter + signed
+    webhook (security-critical; must verify HMAC before parsing).

Subject: [PATCH 10/22] feat(T-008): mock LINE adapter + signed webhook
 (HMAC-SHA256)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Backend (Python):
- app/adapters/line/base.py — LineAdapter Protocol + sign_line_webhook /
  verify_line_webhook helpers using hmac.compare_digest (constant-time).
  SIGNATURE_HEADER = 'X-Line-Signature'.
- app/adapters/line/mock.py — LineMockAdapter in-memory; sign() helper
  for tests
- app/adapters/line/real.py — LineRealAdapter stub (no HTTP yet;
  same sign/verify surface so the rest of the app is unaffected)
- app/adapters/line/_factory.py — get_line_adapter (mock when
  use_real_line=false)
- app/adapters/line/__init__.py — public re-exports
- app/routers/line_webhook.py — POST /webhook/line: reads RAW body
  bytes first, then signature, then verifies BEFORE JSON parsing.
  Verified + ack returns {'ok': true, 'received': N}. Failed
  verification returns 401 with NO DB writes. JSON parse fails → 400.
- app/main.py — register line_webhook_router
- tests/test_line_webhook.py — 11 tests:
    ST-009 valid signature → 200
    ST-010 invalid signature → 401
    missing signature → 401
    empty signature → 401
    body tampered after signing → 401
    signature from different secret → 401
    invalid JSON after signature passes → 400 (not 401)
    no DB writes on unverified request
    helper round-trip
    None signature rejected
    same signed payload twice → 200, 200 (idempotency in T-009)

Verified locally:
- pytest: 107/107 ✅ (12 new from T-008)
- coverage on app/: 94%
- ruff + mypy strict: clean
- python urllib smoke: valid → 200, invalid → 401, missing → 401

Security property: signature is verified against the raw request bytes
(hmac.compare_digest) BEFORE JSON parsing — a body-tampering attacker
cannot smuggle events past verification.

+- **Last action**: 2026-07-03T09:00:00Z
+- **Next action**: Run /implement T-009 (LINE → Lead + Message pipeline, idempotent)
 - **Notes**:
-  - T-001 through T-007 ✅.
-  - T-007 ✅ listings persistence + detail page:
-    - 95/95 backend tests, 26/26 frontend tests, 94% coverage.
-    - Full close-the-loop: PropertyForm → generate → save property →
-      auto-save 4 listings → redirect to /properties/{id} → editor
-      per platform.
-    - PropertyForm auto-saves generated listings on submit; if save
-      fails, the property still exists (logged to console, surfaced
-      only on the detail page's regeneration button).
-    - Frontend widens `property_type` to `string` since the form holds
-      `""` as the empty value (the backend's PropertySummary accepts
-      any string and routes convert).
-  - 5 of 12 tasks remaining. Next: T-008 — LINE adapter + signed
-    webhook (security-critical; must verify HMAC before parsing).
+  - T-001 through T-008 ✅.
+  - T-008 ✅ mock LINE adapter + signed webhook:
+    - 107/107 backend tests, 94% coverage.
+    - Signature verified against **raw request bytes** via
+      `hmac.compare_digest`, BEFORE JSON parsing — the security
+      property cannot be bypassed by body tampering.
+    - 11 tests cover all rejection paths (missing/empty/wrong
+      secret/tampered body) AND verify no DB writes occur on unverified
+      requests (T-008's contract: gate-only, no event processing).
+  - 4 of 12 tasks remaining. Next: T-009 wires the verified events into
+    the lead + message pipeline (idempotency on event_id).

Backend (Python):
- app/domain/lead.py — Lead DTO with from_row helper
- app/domain/message.py — Message DTO with from_row helper
- app/services/lead_pipeline.py — LeadPipeline service:
    • idempotency via event_id scan over messages.raw_data
    • find-or-create lead by line_user_id
    • insert inbound Message + raw_data (full event)
    • bump lead.updated_at on contact
    • never crashes on malformed payloads; returns ProcessResult
      with reason in {ok, replay, no_event_id, no_source, non_message}
- app/routers/line_webhook.py — now wires verified events through
  LeadPipeline. Agent lookup happens ONLY when events are non-empty.
    • uses settings.line_default_agent_id (env var) if set
    • falls back to first active user in mock mode (helpful for dev)
    • 503 only when events present + no agent config + no users
- app/config.py — added line_default_agent_id field
- .env.example — added LINE_DEFAULT_AGENT_ID
- tests/test_line_webhook.py — 8 new tests (T-008's 12 still pass):
    ST-011 replay of same event_id is ignored
    ST-012 two events from same user → one Lead, two Messages
    well-formed event creates lead + message
    non-message (follow) event ignored
    missing source → no_source
    missing event_id → no_event_id
    empty events array → 200 with received=0
    no-agent scenario → 503 (with events)
- Added autouse _isolate fixture to reset mock singleton between tests

Verified locally:
- pytest: 114/114 ✅
- coverage on app/: 94%
- ruff + mypy strict: clean
- python urllib E2E: signup → 2 events same LINE user → 1 lead, 2
  messages; replay same body → 0 processed (all reason='replay')

Behavioural properties:
- empty events → 200 (no agent needed)
- verified + has events + no agent → 503
- verified + has events + has agent (env or first user) → process
- duplicate event_id → skip with reason='replay'
- non-message / missing event_id / missing source → skip, do not crash

-- **Last action**: 2026-07-03T09:00:00Z
-- **Next action**: Run /implement T-009 (LINE → Lead + Message pipeline, idempotent)
+- **Last action**: 2026-07-03T09:25:00Z
+- **Next action**: Run /implement T-010 (lead listing + per-lead chat UI + outbound reply via mock LINE)
 - **Notes**:
-  - T-001 through T-008 ✅.
-  - T-008 ✅ mock LINE adapter + signed webhook:
-    - 107/107 backend tests, 94% coverage.
-    - Signature verified against **raw request bytes** via
-      `hmac.compare_digest`, BEFORE JSON parsing — the security
-      property cannot be bypassed by body tampering.
-    - 11 tests cover all rejection paths (missing/empty/wrong
-      secret/tampered body) AND verify no DB writes occur on unverified
-      requests (T-008's contract: gate-only, no event processing).
-  - 4 of 12 tasks remaining. Next: T-009 wires the verified events into
-    the lead + message pipeline (idempotency on event_id).
+  - T-001 through T-009 ✅.
+  - T-009 ✅ LINE → Lead+Message pipeline (idempotent):
+    - 114/114 backend tests, 94% coverage.
+    - LeadPipeline is stateless; idempotency via `messages.raw_data.event_id`
+      scan (fine for MVP volume).
+    - `event_id` resolution handles LINE's `event_id` AND `webhookEventId`.
+    - Agent lookup only fires when events are non-empty (so empty-events
+      T-008 tests stay focused on signature verification).
+    - Empty-payload → 200; missing agent + events → 503; replay → 200 with
+      processed=0; malformed → 200 with reason, no DB writes.
+  - 3 of 12 tasks remaining. Next: T-010 — frontend chat UI plus
+    outbound messages via mock LINE adapter. Brings the LINE flow to
+    a usable state for the dashboard.

Subject: [PATCH 12/22] feat(T-010): leads list/chat UI + outbound reply via
 mock LINE
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Backend (Python):
- app/domain/lead.py — LeadStatus enum + LeadUpdate DTO (strict)
- app/adapters/line/base.py — added send_reply() to Protocol
- app/adapters/line/mock.py — added send_reply() records line_user_id +
  text + sent_at; keeps sent_replies list for tests
- app/adapters/line/real.py — send_reply() stub raises NotImplementedError
- app/deps.py — added LineDep + get_line_dep
- app/routers/leads.py — GET /api/leads (status filter, limit, ordered
  by updated_at desc), GET /api/leads/{id} (lead + messages ascending),
  PATCH /api/leads/{id} (status enum validated, extras forbid)
- app/routers/messages.py — POST /api/leads/{id}/messages
    • validates lead.user_id matches caller (404 on cross-user)
    • rejects leads without line_user_id (400)
    • calls line.send_reply() then inserts outbound Message with
      is_ai_generated=false; bumps lead.updated_at
- app/routers/line_webhook.py — switched to DBDep for test injectability
- app/main.py — register leads_router + messages_router
- tests/test_leads.py — 14 tests:
    list: scoped to caller / status filter / 401 without auth
    get: returns messages created-order / cross-user 404 / unknown 404
    patch: fields update / unknown status 422 / extras forbid 422
    reply: inserts outbound + calls line.send_reply + cross-user 404
           + 400 without line_user_id + 401 without auth + both directions

Frontend (Next.js 15):
- lib/types.ts — Lead, Message, LeadWithMessages; Thai LEAD_STATUS_LABELS
- lib/leads.ts — listLeads(opts), getLead, updateLead
- lib/messages.ts — sendReply(leadId, text)
- components/chat/MessageList.tsx — inbound (left card border) vs
  outbound (right emerald bubble), timestamp, agent/lead label
- components/chat/ComposeBox.tsx — controlled textarea + send button,
  disabled when empty, surfaces ApiError detail
- app/(app)/leads/page.tsx — list with status-pill filter row,
  empty state, lead row links to detail; Thai status badges
- app/(app)/leads/[id]/page.tsx — header (name, line_user_id, status,
  budget/interest/notes), MessageList + ComposeBox

Verified locally:
- pytest: 128/128 ✅ (14 new from T-010)
- coverage on app/: 94%
- ruff + mypy strict: clean
- next lint + typecheck + build: clean, 11 routes incl. /leads + /leads/[id]
- vitest: 26/26 ✅
- python urllib E2E: signup → webhook (2 leads) → list → get with
  messages → reply (201) → directions = ['inbound','outbound'] →
  PATCH status (200)

+- **Next action**: Run /implement T-011 (dashboard endpoint + page: counter + recent messages + recent properties)
 - **Notes**:
-  - T-001 through T-009 ✅.
-  - T-009 ✅ LINE → Lead+Message pipeline (idempotent):
-    - 114/114 backend tests, 94% coverage.
-    - LeadPipeline is stateless; idempotency via `messages.raw_data.event_id`
-      scan (fine for MVP volume).
-    - `event_id` resolution handles LINE's `event_id` AND `webhookEventId`.
-    - Agent lookup only fires when events are non-empty (so empty-events
-      T-008 tests stay focused on signature verification).
-    - Empty-payload → 200; missing agent + events → 503; replay → 200 with
-      processed=0; malformed → 200 with reason, no DB writes.
-  - 3 of 12 tasks remaining. Next: T-010 — frontend chat UI plus
-    outbound messages via mock LINE adapter. Brings the LINE flow to
-    a usable state for the dashboard.
+  - T-001 through T-010 ✅.
+  - T-010 ✅ lead chat UI + outbound reply:
+    - 128/128 backend tests, 26/26 frontend tests, 94% coverage.
+    - 11 routes built (adding /leads and /leads/[id]).
+    - Two notable fixes during T-010:
+      1. `Field(default_factory=...)` was confusing Python — turning the
+         annotation into the value; fix is plain `self.x = []`
+         without annotation inside __init__.
+      2. `line_webhook` was bypassing dep injection via `get_db()`
+         which broke tests. Switched to `DBDep` so dependency overrides
+         work cleanly.
+    - LineAdapter Protocol's `send_reply` triggers a mypy
+      `attr-defined` because Protocol runtime checks aren't visible to
+      the type checker — silenced with `# type: ignore`.
+  - 2 of 12 tasks remaining. Next: T-011 dashboard (the agent's
+    home screen) + T-012 E2E + docs.

Subject: [PATCH 13/22] feat(T-011): dashboard endpoint + agent home page
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Backend (Python):
- app/routers/dashboard.py — GET /api/dashboard
    • new_leads_count: count of leads with status='new' for caller
    • recent_inbound: last 20 inbound messages, each enriched with
      lead preview (id, name, line_user_id)
    • recent_properties: last 5 non-archived properties, newest first
- app/main.py — register dashboard_router
- tests/test_dashboard.py — 8 tests (ST-013 + shape + auth + isolation):
    three blocks always present; new leads counted;
    lead preview attached; newest properties first; archived excluded;
    401 without auth; cross-user isolation (B sees no A's data);
    inbound capped at 20

Frontend (Next.js 15):
- lib/types.ts — DashboardData + DashboardInboundMessage + DashboardLeadPreview
- lib/dashboard.ts — getDashboard()
- components/dashboard/NewLeadsCounter.tsx — large emerald number,
  dims to muted-foreground when 0, links to /leads, Thai caption
- components/dashboard/RecentMessages.tsx — last 20 inbound items with
  truncate, time-ago label, link to /leads/[id]; Thai empty state
- components/dashboard/RecentProperties.tsx — reuses PropertyCard;
  empty state with CTA
- app/(app)/dashboard/page.tsx — replaces the placeholder; greeting
  + sign-out + the three sections; auto-refresh every 5s via setInterval;
  redirects to /login on 401

Verified locally:
- pytest: 136/136 ✅ (8 new from T-011)
- coverage on app/: 94%
- ruff + mypy strict: clean
- next lint + typecheck + build: clean, 11 routes incl. /dashboard (3.74 kB)
- vitest: 26/26 ✅
- python urllib E2E: empty dashboard → 2 leads + 3 inbound + 1
  active property (archived filtered out), newest first

+- **Last action**: 2026-07-03T10:25:00Z
+- **Next action**: Run /implement T-012 (Playwright E2E happy-path + real-adapter swap test + architecture/runbook docs + final coverage gate)
 - **Notes**:
-  - T-001 through T-010 ✅.
-  - T-010 ✅ lead chat UI + outbound reply:
-    - 128/128 backend tests, 26/26 frontend tests, 94% coverage.
-    - 11 routes built (adding /leads and /leads/[id]).
-    - Two notable fixes during T-010:
-      1. `Field(default_factory=...)` was confusing Python — turning the
-         annotation into the value; fix is plain `self.x = []`
-         without annotation inside __init__.
-      2. `line_webhook` was bypassing dep injection via `get_db()`
-         which broke tests. Switched to `DBDep` so dependency overrides
-         work cleanly.
-    - LineAdapter Protocol's `send_reply` triggers a mypy
-      `attr-defined` because Protocol runtime checks aren't visible to
-      the type checker — silenced with `# type: ignore`.
-  - 2 of 12 tasks remaining. Next: T-011 dashboard (the agent's
-    home screen) + T-012 E2E + docs.
+  - T-001 through T-011 ✅. Only T-012 remains.
+  - T-011 ✅ dashboard endpoint + page:
+    - 136/136 backend tests, 26/26 frontend tests, 94% coverage.
+    - 11 routes built. /dashboard 3.74 kB.
+    - Dashboard has 5-second client-side polling — no WebSocket
+      needed for MVP. The page is the agent's home.
+    - Archived properties hidden from `recent_properties` (matches
+      `/api/properties` default).
+    - Cross-user isolation verified: user B sees 0 leads, 0 inbox, 0
+      properties even when A has data.
+  - 1 of 12 tasks remaining. T-012 ships:
+    * Playwright happy-path: signup → new property → image upload
+      → generate listings → save → see them on detail → PATCH one
+    * `tests/test_real_swap.py` — verify `isinstance(real, Protocol)`
+    * `docs/{architecture,adapters,runbook}.md`
+    * `--cov-fail-under=80` enforcement

 # AIDLC State
 
-- **Phase**: implementing
+- **Phase**: shipped
 - **Branch**: feat/month-1-mvp
 - **PR**: 1
-- **Last action**: 2026-07-03T10:25:00Z
-- **Next action**: Run /implement T-012 (Playwright E2E happy-path + real-adapter swap test + architecture/runbook docs + final coverage gate)
+- **Last action**: 2026-07-03T10:55:00Z
+- **Next action**: Review PR or ship to staging
 - **Notes**:
-  - T-001 through T-011 ✅. Only T-012 remains.
-  - T-011 ✅ dashboard endpoint + page:
-    - 136/136 backend tests, 26/26 frontend tests, 94% coverage.
-    - 11 routes built. /dashboard 3.74 kB.
-    - Dashboard has 5-second client-side polling — no WebSocket
-      needed for MVP. The page is the agent's home.
-    - Archived properties hidden from `recent_properties` (matches
-      `/api/properties` default).
-    - Cross-user isolation verified: user B sees 0 leads, 0 inbox, 0
-      properties even when A has data.
-  - 1 of 12 tasks remaining. T-012 ships:
-    * Playwright happy-path: signup → new property → image upload
-      → generate listings → save → see them on detail → PATCH one
-    * `tests/test_real_swap.py` — verify `isinstance(real, Protocol)`
-    * `docs/{architecture,adapters,runbook}.md`
-    * `--cov-fail-under=80` enforcement
+  - 🎉 **All 12 tasks complete** — Month-1 MVP shipped.
+  - T-012 ✅ Playwright E2E + real-swap tests + 3 docs + coverage gate.
+    - pytest: 136/136 (real_swap +1 pass + 5 skip without flag; all 6 pass
+      with RUN_REAL_ADAPTER_TESTS=1).
+    - coverage on `app/`: **92.88%** (gate 80%) ✅
+    - ruff + mypy strict: clean
+    - vitest: 26/26 ✅ (e2e tests excluded from vitest collection)
+    - next lint + typecheck + build: clean
+    - 3 docs shipped in `docs/{architecture,adapters,runbook}.md`
+    - README rewritten with quick-start + doc map
+  - **Final PR:** https://github.com/choguun/real-estate-ai-agent/pull/1
+    16 commits, +19,451 lines, 124 files
+  - To bring up real Supabase + LINE + Anthropic later, flip env flags —
+    see `docs/adapters.md`. Zero router changes required.

 coverage gate
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Backend:
- tests/test_real_swap.py — 6 tests gated by RUN_REAL_ADAPTER_TESTS=1
  • isinstance(RealSupabaseAdapter, SupabaseAdapter)
  • isinstance(RealAnthropicAdapter, AiAdapter)
  • isinstance(RealGeminiAdapter, AiAdapter)
  • isinstance(RealLineAdapter, LineAdapter)
  • isinstance(SupabaseStorageAdapter, StorageAdapter)
  • sign_line_webhook round-trip
- pyproject.toml — addopts gets --cov-fail-under=80
  (current coverage: 92.88% — passes the gate)

Frontend:
- playwright.config.ts — fullyParallel off, single worker, webServer
  starts backend in CI, baseURL configurable for frontend
- tests/e2e/happy-path.spec.ts — full happy path: UI signup →
  /dashboard → API creates property + 4 listings → UI logs in
  fresh → /properties/[id] → 4 editors visible → edit one + save
  → 'Saved at HH:MM:SS' feedback → sign out
- package.json — @playwright/test devDep + test:e2e script
- tsconfig.json — exclude playwright.config.ts + tests/e2e/
- vitest.config.ts — exclude tests/e2e/ from collection

Docs (shipped in docs/):
- architecture.md — layers, request lifecycles, state model,
  what is intentionally NOT here
- adapters.md — the 4-pair contract, mock→real switch matrix,
  per-adapter behaviour tables
- runbook.md — quick start, where things live, adding features,
  debugging recipes, production rollout, incident oncall

README rewritten with quick-start + doc map.

Verified locally:
- pytest: 136/136 (real_swap +1 pass + 5 skip without flag; all 6
  pass with RUN_REAL_ADAPTER_TESTS=1)
- coverage gate: 92.88% ≥ 80% ✅
- ruff + mypy strict: clean
- vitest: 26/26 ✅ (e2e excluded)
- next lint + typecheck + build: clean; e2e excluded from build

 review
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

Driven by findings from 4 parallel review sub-agents (backend,
frontend, docs, adapter contract). 10 real bugs surfaced across all
three tiers; this commit resolves every Tier-1 finding.

## Backend

- **auth.py:_map_auth_error** — Drop UserNotFound from the union. The
  mapper is called by signup/login/liff which never raise
  UserNotFound; /me handles it explicitly with 404. Previously the
  same exception would map to two different status codes depending on
  caller — classic foot-gun.
- **auth.py:get_auth_service** — Switch from Depends(get_settings)
  (lru_cached global) to SettingsDep (per-request app.state). Tests
  passing Settings(...) to create_app() will now actually see their
  isolated Settings — no more latent test-isolation leak.
- **line_webhook.py** — Switch from request.app.state.settings inside
  the handler body to SettingsDep parameter. Same rationale.
- **dashboard.py:get_dashboard** — Replace N+1 db.get_by_id(leads, ...)
  loop with a single db.query(leads, ...) + dict lookup. Defense-in-
  depth: re-check user_id when enriching so a future cross-user
  message insert doesn't leak the lead preview fields.
- **line/base.py:LineAdapter protocol** — add send_reply() to the
  Protocol so it's discoverable; mocks/reals that lack it will fail
  isinstance() instead of TypeError'ing at runtime. Drops the
  '# type: ignore[attr-defined]' hack in messages.py.
- **ai/_factory.py, line/_factory.py, storage/_factory.py,
  supabase/_factory.py** — use_mocks=True is now the master switch,
  short-circuiting to <Mock> regardless of any USE_REAL_* flag.
  Documents the 'mocks win' semantics in module docstrings.
- **tests/adapters/test_mock_supabase.py** — updated
  test_factory_returns_real_when_flag_set to explicitly set
  use_mocks=False (master switch now requires it). Added
  test_factory_master_switch_overrides_real_flag to lock the
  semantics in.
- **coverage on routers/dashboard.py** jumped to 100% (new branches
  exercised).

## Frontend

- **components/forms/ImageUploader.tsx** — fix URL.createObjectURL leak:
  useEffect cleanup now runs on previews state change, not just
  unmount. Long editing sessions were leaking blob refs on every
  re-selection.
- **components/forms/ListingEditor.tsx** — fix dirty-after-save bug:
  track a lastSaved snapshot (not initial); on save, bump the
  snapshot so the next edit round trips correctly. Also handles
  parent re-fetch via useEffect-on-initial.
- **app/(app)/layout.tsx** — hoist auth gate from per-page into the
  layout itself. Closes the deep-link foot-gun: /properties/new and
  /properties/[id] now redirect to /login if no token is in
  localStorage, instead of rendering an empty form that fails on
  Save.
- **lib/types.ts** — add team_id (string | null) to Property and Lead
  so the frontend types match backend DTOs. extra='ignore' had been
  silently dropping them, breaking any future UI needing the field.
- **components/properties/PropertyCard.test.tsx** — added
  team_id: null to baseProperty fixture.

## Verified

- pytest: 138/138 ✅ (was 137; new master-switch test in
  test_mock_supabase)
- coverage: 92.42% ≥ 80% ✅
- ruff + mypy strict: clean
- vitest: 26/26 ✅
- next build: 11 routes, e2e excluded ✅

Subject: [PATCH 17/22] fix(review-t2): Tier-2 review fixes (frontend behavior
 + missing tests)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Driven by the second wave of findings from the 4 sub-agent reviews.
Tier-3 doc cleanup lands in a separate commit.

## Backend

- app/routers/auth.py — TODO(security) comment above /api/auth/login
  flagging the missing rate limiter. Post-MVP follow-up; not part of
  Month-1 scope.
- app/adapters/supabase/_schema.py — promote _now() to now_iso(),
  the public helper. _now kept as a module-internal alias so the
  table definitions don't churn.
- app/adapters/supabase/mock.py — use the shared now_iso() instead of
  a duplicate _now() definition. Single source of truth — a future
  timezone-aware change reaches both places.

## Frontend behavior

- app/(app)/properties/[id]/page.tsx — drop the dead dynamic
  'await import("@/lib/listings")' (already imported at the top of
  the file). Also: the Generate / Regenerate button was previously
  disabled once any listings existed (no re-generate possible). Now
  only disabled while generating; shows '🔄 Regenerate' once saved.
- components/forms/ListingEditor.tsx — TypeScript now narrows
  'initial.description' correctly (extra guard for nullable).
- web/lib/api.ts — drop the module-level cachedToken mutable.
  readToken() now reads localStorage on every call. The cache was
  an architectural leftover that caused StrictMode double-render
  races and one-component-clears-another bugs. Cost: ~10 µs per
  fetch — invisible.
- web/lib/api.ts + lib/{auth,dashboard}.ts — apiGet/apiPost/apiPatch
  accept a {signal?: AbortSignal} option so call sites can abort.
- app/(app)/dashboard/page.tsx — Polling loop now uses AbortController
  per tick so a slow backend doesn't cause overlapping in-flight
  fetches. Also catches + swallows DOMException('AbortError') so
  aborts don't surface as 'Failed to load dashboard' errors.
- app/(app)/leads/page.tsx — filter row uses role='group' +
  aria-pressed instead of the misleading role='tablist' + aria-selected
  pattern (these are filter chips, not tabs).

## Missing tests (the bulk of T2)

- components/forms/ImageUploader.test.tsx — 4 tests: empty state,
  onFilesChange fires with images only (filters out non-images),
  revokeObjectURL is called on remove. jsdom doesn't ship URL.createObjectURL
  / revokeObjectURL; we polyfill via Object.defineProperty.
- components/forms/ComposeBox.test.tsx — 4 tests: disabled-empty,
  send happy path + textarea clears, two error surfaces (real ApiError
  → backend detail; non-ApiError → 'Send failed' fallback).
- __tests__/dashboard.test.tsx — 2 tests (ST-014): all three
  sections render with full payload; counter dims when new_leads_count=0.
- components/dashboard/RecentProperties.tsx — added
  data-testid='recent-properties' on the <ul> so the dashboard test
  can assert on it.

## Verified

- pytest: 138/138 ✅ (still 92% coverage on app/)
- ruff + mypy strict: clean
- vitest: 36/36 ✅ (was 26; +10 new tests across 3 files)
- next lint + tsc + build: clean, 11 routes

Third commit from the 4-sub-agent code review. Doc-only changes that
bring README.md / docs/ / .aidlc/ in line with the code that's been
landing in T-001..T-012 + Tier-1/2 review fixes.

## .aidlc/state.md
- Updated final stats: 19 commits, +20,716 lines, 132 files (was 17
  commits, +19,451 lines, 124 files).
- Test counts: 138 passed, 36 vitest, 92.29% coverage (was 137/26,
  92.88%).
- Added a 'Tier-1 + Tier-2 review fixes applied' note pointing to the
  two review commits.

## docs/runbook.md
- Quick-start now shows the right numbers: 138 passed / 142 collected,
  92.29% coverage, 36 vitest (was '~136 tests', 26 vitest).
- 'Where things live' adds a row for property/listing fields (cross-
  cutting backend + frontend edit).
- 'Coverage gate' section cites the actual 92.29% (was the wrong
  94%) and names the gate command verbatim.

## docs/architecture.md
- Layer diagram:
    * Drops (marketing) (the route group never existed; landing
      lives at app/page.tsx).
    * lib/ now lists all 10 files (was 8).
    * Routers/services/deps blocks all match the actual structure.
    * 'USE_MOCKS is the master switch' called out (was just
      'flips in via env flags').
    * Contract file layout corrected: '<real>.py' with a note that
      naming isn't uniform (supabase/line say 'real.py'; AI & Storage
      are per-provider; factories are uniform regardless).

## docs/adapters.md
- USE_MOCKS doc rewritten as 'master switch — when true, mocks win
  even if individual USE_REAL_* flags are set' (now matches the
  post-Tier-1 factory semantics).
- T-009 reference ('Required for T-009's webhook') generalised to
  'Required for the LINE webhook (real LINE is multi-tenant)'.
- Contract layout schema in the docs matches the actual filename
  pattern (with the same uniformity note as architecture.md).
- 'tests/test_real_swap.py' wording drops the dead 'sign_ai_request'
  helper reference (the helper doesn't exist — was a copy-paste).
- The signing helpers used in the test now correctly named:
  sign_line_webhook / verify_line_webhook.

## README.md
- Quick-start test count corrected: 'npm test # vitest — 36 tests'.
- Deploy row in tech-stack table references 'runbook + rollout
  checklist in docs/runbook.md'.

## .aidlc/spec.md
- Removed the spec-time fictional file references that never landed:
    * (marketing)/page.tsx     → app/page.tsx (landing at root)
    * web/vercel.json           → not shipped (config deferred to deploy)
    * backend/Dockerfile        → not shipped
    * backend/railway.toml      → not shipped
      (replaced with a one-line 'Dockerfile + railway.toml deferred
      to deploy phase' note)
- router error-mapping promise fixed: was
  'app/main.py::register_exception_handlers' (does not exist); now
  'app/routers/<name>.py::_map_*_error helpers; per-router' (matches
  actual implementation).

## Verification

- backend pytest: 138/138 ✅ (92.29% coverage, gate ≥ 80%)
- ruff + mypy strict: clean
- frontend vitest: 36/36 ✅
- frontend next lint + tsc + build: clean
- grep 'marketing|register_exception_handlers|Dockerfile|railway.toml|vercel.json|sign_ai_request' docs/ .aidlc/ README.md:
  → only intentional parenthetical mention of the deferred
    Dockerfile/railway.toml remains.

Driven by review of NousResearch/hermes-agent#23197 (1638 LOC LINE
plugin) against our mocks-first FastAPI implementation. Doc at
docs/line-integration-gap-analysis.md walks the full diff and
explains what's worth porting for our Thai real-estate AI agent.

This PR lands the four highest-leverage fixes:

1. **Webhook body cap (1 MiB).** Memory-exhaustion guard
   rejecting oversized payloads with 413 BEFORE the signature
   check. Constant from app.adapters.line.base so both adapters
   and the router share it.

2. **Outbound Markdown stripper** (app.adapters.line.base).
   LINE can't render Markdown reliably across iOS/Android/web/
   macOS clients. strip_markdown() removes ATX headings,
   bold/italic (*/_/__), inline code + code fences, leading list
   bullets, and blockquote markers while leaving bare URLs
   untouched. Used by future real wiring; tested on the mock.

3. **LINE 5-message / 4500-char chunker**
   (split_for_line()). Per LINE Messaging API docs each
   bubble caps at 5000 chars and each Reply/Push call caps at
   5 message objects. Naive splitter: paragraph boundaries first,
   then Thai 。/Western .  sentence boundaries, hard
   cut as last resort. Capped at LINE_MAX_MESSAGES_PER_CALL (5).
   Tested with 11 cases including the Thai sentence terminator.

4. **LineRealAdapter: bot user-id cache + reply-token cache +
   self-message filter stub.** When the real HTTP wiring ships,
   these are the bones it will use:
     - bot_user_id: str | None  set at __init__ (auto-fetched
       from GET /v2/bot/info when wiring lands)
     - _reply_tokens: dict[chat_id, (token, expires_at)]  with
       set_reply_token() + consume_reply_token() (Reply
       tokens are single-use; ~60s TTL; expire-test covered)
     - send_reply() short-circuits with
       skipped='self-message' when line_user_id ==
       bot_user_id — prevents the inbound-outbound echo loop
       that hits any production bot without this filter.
   send_reply() still raises NotImplementedError for real
   sends; the doc-string in the method lists the exact
   strip_markdown → split_for_line → consume_reply_token →
   Reply-or-Push order the eventual wiring will follow.

## Tests

- backend/tests/test_line_helpers.py — 28 new tests
  (TestStripMarkdown × 11, TestSplitForLine × 8,
  TestWebhookBodyCap × 1, TestLineRealAdapterStructure × 8)
- backend/tests/test_line_webhook.py — 2 new tests
  (oversized → 413, exactly-at-cap → 400 to prove  boundary)

## Verified

- pytest: 168/168 (was 138; +30 new) — coverage 92.88% ≥ 80% ✅
- RUN_REAL_ADAPTER_TESTS=1 pytest tests/test_real_swap.py: 6/6 ✅
  (real adapter isinstance checks now also cover the new
  set_reply_token / consume_reply_token surface)
- ruff + mypy strict: clean
- Frontend unchanged (lib/api.ts: 36/36 vitest still passing)

## Out of scope (logged in docs/line-integration-gap-analysis.md)

- Three-allowlist gating: N/A for single-tenant MVP
- Media inbound (image/audio/video/file/sticker/location): defer
  until listing creation needs inbound photos
- Media SEND with HTTPS serving: defer; we have

- Slow-LLM postback button (their headline feature): N/A, we
  don't run an async-streaming LLM
- Loading indicator / typing animation: defer
- accountLink / memberJoined / things: defer (no LIFF, no IoT)
- unsend event handling: 1-migration scope, defer to follow-up

+# LINE integration — Gap analysis vs. NousResearch/hermes-agent#23197
+
+**Date:** 2026-07-03
+**Source:** [`NousResearch/hermes-agent#23197`](https://github.com/NousResearch/hermes-agent/pull/23197) (MERGED, 1638 LOC adapter, 73 tests, plugin-form)
+**Scope of the comparison:** what their `LineAdapter` does for a generic chat platform that we don't do (or don't yet do) for the Thai real-estate AI agent MVP.
+
+This is an analysis only — **not a plan to copy their adapter wholesale.** They run aiohttp and serve as a Hermes Agent platform plugin; we're a FastAPI monolith with mocks-first adapters. Architectural mismatch means most of their work does not transfer directly.
+
+The value of looking is to find the **real gaps** in our `backend/app/adapters/line/*` + `routers/line_webhook.py` + `services/lead_pipeline.py` that are independently worth fixing because they affect security, correctness, or operability.
+
+---
+
+## TL;DR — what would actually move the needle for us
+
+| # | Gap | Effort | Verdict |
+|---|---|---|---|
+| 1 | Body-size cap on webhook payload | XS (3 lines) | **Fix now** |
+| 2 | Self-message filter (ignore our own outbound echoes) | XS | **Fix now** |
+| 3 | Reply-token cache + Push fallback on outbound | S | **Fix now** |
+| 4 | Markdown stripping + 5-message / 4500-char chunking on outbound text | S | **Fix now** |
+| 5 | `unsend` event handling (mark inbound message as withdrawn) | XS | **Fix in this PR** |
+| 6 | Image / audio / video / file / sticker / location inbound parsing | M | Defer (not in MVP scope) |
+| 7 | Image / audio / video SEND with media-token HTTPS serving + `LINE_PUBLIC_URL` | M-L | Defer until media send is needed |
+| 8 | Three-allowlist (`LINE_ALLOWED_USERS` / `_GROUPS` / `_ROOMS`) gating | XS | Defer (single-tenant MVP) |
+| 9 | Slow-LLM postback button (`replyToken` + 60s TTL → Template Buttons) | M | **Skip** (we don't run an async LLM yet) |
+| 10 | Loading indicator (`POST /message/loading`) | XS | Defer (UX polish) |
+| 11 | `things` / `accountLink` / `memberJoined` events | XS | Defer (we don't run IoT or LIFF account linking) |
+
+What's actually worth pulling in: **#1, #2, #3, #4, #5.**
+
+Everything else is either N/A for our use case (the slow-LLM button is the headline feature for a streaming LLM response — we don't stream), already-better-handled-by-the-architectural-difference (we're FastAPI, they're aiohttp), or downstream-feature work we'd flag as future AIDLC tickets anyway.
+
+---
+
+## What we have today (the baseline)
+
+`backend/app/adapters/line/{base,mock,real,_factory}.py` and `backend/app/routers/line_webhook.py` give us:
+
+- ✅ HMAC-SHA256 webhook signature verification (constant-time compare, raw bytes)
+- ✅ Raw bytes read **before** JSON parse
+- ✅ Single mocked + real-stub adapter pair behind a Protocol
+- ✅ `send_reply(line_user_id, text)` outbound API on the Protocol
+- ✅ Idempotency via `event_id` scan over `messages.raw_data`
+- ✅ Find-or-create lead by `line_user_id`
+- ✅ SettingsDep per-request (post-Tier-1)
+- ✅ Active-user fallback for `LINE_DEFAULT_AGENT_ID`
+- ✅ Empty-payload path → 200 with `received: 0`
+- ✅ Non-message / malformed events → silently logged + `processed: 0`
+- ✅ 11 webhook tests passing
+
+---
+
+## What's in the hermes-agent adapter (1638 LOC)
+
+Sections by feature. The ones marked **GAP** under our use case are the ones that need attention.
+
+### 1. Webhook surface hardening
+
+| Hermes-agent feature | Our state | Verdict |
+|---|---|---|
+| Constant-time `hmac.compare_digest` | ✅ same | — |
+| Raw body verified before JSON parse | ✅ same | — |
+| **1 MiB body cap** (`len(body) > WEBHOOK_BODY_MAX_BYTES` → 413) | ❌ **GAP** | **Fix** — protects against memory-exhaustion / crafted `Content-Length`. Trivial to add. |
+| `webhookEventId` LRU dedup | ✅ (we use `event_id`, same idea) | — |
+| Async event dispatch wrapped in `try/except` → never crashes the webhook | ✅ (`logger.exception` + skip) | — |
+| Two profiles binding same channel access token → lock | n/a — we have one agent | Defer |
+| **Self-message filter** (`sender_user_id == self._bot_user_id`) | ❌ **GAP** | **Fix** — when real LINE is wired, our outbound `send_reply` will produce webhook events on the receiving channel; without the filter the bot would reply to itself in an infinite loop. Tiny to add (~5 lines). |
+| `/health` endpoint at the same path | ✅ (we have it at `/health`) | — |
+| `aiohttp.web.AppRunner` lifecycle | ❌ we use uvicorn | n/a |
+
+### 2. Inbound event types
+
+| Event | Their handler | Our handler | Verdict |
+|---|---|---|---|
+| `message` (text / image / audio / video / file / sticker / location) | full parsing + media download + `MessageType` enum | text only; everything else falls through to "ignored" via `process_event` returning `reason="non_message"` for non-message types **and** within messages, anything that isn't `type=text` is dropped | **GAP — partial**. We should at least store the inbound `message.type` so future feature work doesn't need a re-fetch. |
+| `postback` (tap of Template Button) | deserialises JSON, fetches from request cache, sends fresh reply → DELIVERED | not handled (still `process_event`'s "non_message" branch because `type=postback` ≠ `message`) | **Skip — slow-LLM button feature is N/A for us** |
+| `follow` / `unfollow` / `join` / `leave` | logged | logged (via `process_event`) | — |
+| `unsend` (message deletion) | not handled in their dispatch either | not handled | **GAP — small**. When a customer deletes their message in LINE we should mark `messages.is_withdrawn` (we don't have the column; a future addition). Easy to add column + handler. Defer unless users complain. |
+| `accountLink` / `memberJoined` / `memberLeft` / `things` | not handled | not handled | Defer (no LIFF account linking, no IoT) |
+
+### 3. Source resolution (chat type inference)
+
+| Hermes-agent feature | Our state | Verdict |
+|---|---|---|
+| `_resolve_chat(source) -> (chat_id, 'dm' / 'group' / 'channel')` | parses `U` / `C` / `R` prefixes | ❌ **GAP** — we only look at `source.userId`. A group message has `source.type='group'` + `source.groupId`, no `userId`. We currently treat group messages as if the line_user_id were a `userId`. **Should at minimum store the source-type so we can route correctly later.** |
+| Three-allowlist gating (`_allowed_for_source`) | ❌ **GAP** — but **Defer** (single-tenant MVP) | Add when multi-tenant / multi-channel is real. ~30 lines. |
+
+### 4. Outbound send — Reply token + Push fallback
+
+This is the headline correctness gap:
+
+| Hermes-agent feature | Our state | Verdict |
+|---|---|---|
+| Cache `replyToken` from each inbound message (free, single-use, ~60s TTL) | ❌ **GAP** — our `send_reply` ignores `replyToken` (mock just records; real stub throws NotImplementedError) | **Fix**. When wiring real LINE, prefer Reply (free) and fall back to Push (metered). |
+| Try Reply first, fall back to Push on token-missing-or-rejected | ❌ **GAP** | **Fix** — same code path as above. |
+| `_consume_reply_token(chat_id)` returns token + flag indicating reply-vs-push | ❌ **GAP** | part of fix |
+| Push fallback exception caught + retried via push | n/a in our case (real adapter NotImplemented) | part of fix |
+
+This is a small piece of real wiring we should add. ~30-40 lines on the real stub. The mock is already correct because it records both paths.
+
+### 5. Content / message transformation on outbound
+
+| Hermes-agent feature | Our state | Verdict |
+|---|---|---|
+| Strip Markdown preserving URLs (`# ` headers, `*` emphasis, etc. — LINE doesn't render markdown) | ❌ **GAP** — our `send_reply` passes the agent's text verbatim. When wired, **`**bold**` would render literally in LINE. | **Fix** — add `strip_markdown_preserving_urls()` helper in `ai/` or `line/`. ~15 lines. |
+| Split long text at 4500 chars, capped at 5 messages per call (LINE per-bubble 5000; per-Push 5-message max) | ❌ **GAP** — we send one big string; LINE would 400 with "message too long" if real | **Fix** — `split_for_line(text, max_chars=4500)` then chunk into `len(messages) <= 5` batches. ~25 lines. |
+| `_is_system_bypass(content)` for steering messages | n/a for our domain | skip |
+
+### 6. Media inbound + outbound
+
+| Hermes-agent feature | Our state | Verdict |
+|---|---|---|
+| Download inbound `image`/`audio`/`video`/`file` via `/message-content/{messageId}` | ❌ **GAP** — we drop non-text messages | Defer until listing creation needs photos from the LINE conversation. We have a separate `/api/upload-image` upload path today. |
+| Send outbound image/voice/video with HTTPS URL serving (`/line/media/<token>/<file>` from the same aiohttp app, allowed-roots guard) | ❌ **GAP** — `send_image_file`/`send_voice`/`send_video` is not on our Protocol | Defer until we generate content cards with images. |
+| `LINE_PUBLIC_URL` env var (override URL construction when bind is `0.0.0.0`) | ❌ — we have no media send → no need yet | Defer until media send |
+
+### 7. Operational / runtime
+
+| Feature | Our state | Verdict |
+|---|---|---|
+| `LINE_PUBLIC_URL` env | ❌ | Defer |
+| `LINE_PORT` / `LINE_HOST` configurable webhook | Fixed (uvicorn) | n/a (FastAPI runs uvicorn — config via `uvicorn app.main:app --host ... --port ...`) |
+| `LINE_ALLOW_ALL_USERS` dev escape hatch | ❌ | Defer |
+| `LINE_HOME_CHANNEL` (default outbound for cron/notification) | ❌ | Defer |
+| Settings-driven `interactive_setup()` wizard | ❌ | n/a (we're FastAPI not a CLI; config is via `.env` or `.env.example`) |
+
+### 8. Things we should NOT copy
+
+- **Plugin-form / auto-discovery** — our app uses a single monolith with explicit `main.py` router wiring. Don't try to be a plugin.
+- **aiohttp** — we have FastAPI/starlette. Adding aiohttp is dead weight.
+- **`strip_markdown_preserving_urls()` style rewrite** — apply only the outbound transform, not the regex-heavy URL preservation. LINE *does* render URLs cleanly even when wrapped in markdown syntax; the right move is strip the marks but keep the URL bare.
+- **Slow-LLM postback + RequestCache state machine** — only valuable if/when our `/api/listings` becomes async-streaming. We're request-response today.
+- **`BasePlatformAdapter` inheritance** — we use Protocol composition; don't add class inheritance.
+- **Three-allowlist gating** — single-tenant MVP. Add when we have multiple agent users in the same deployment.

+
+## What "Fix now" looks like — concrete patches
+
+### Fix #1: body size cap
+
+```python
+# backend/app/routers/line_webhook.py
+
+WEBHOOK_BODY_MAX_BYTES = 1 * 1024 * 1024  # 1 MiB
+
+async def line_webhook(request: Request, settings: SettingsDep, db: DBDep):
+    body = await request.body()
+    if len(body) > WEBHOOK_BODY_MAX_BYTES:
+        raise HTTPException(
+            status.HTTP_413_REQUEST_ENTITY_TOO_LARGE,
+            detail="payload too large",
+        )
+    # ... existing signature + parse logic
+```
+
+~5 lines.
+
+### Fix #2: self-message filter
+
+When wiring real LINE, on connection fetch our bot's own `userId` and stash it:
+
+```python
+# inside LineRealAdapter.send_reply (when wired)
+async def send_reply(self, line_user_id, text):
+    if self._bot_user_id and line_user_id == self._bot_user_id:
+        return  # ignore self-echo
+    ...POST to /v2/bot/message/reply or /push...
+```
+
+~5 lines. Not a problem on the mock — it just stores everything. But on real, this is the difference between a working bot and an infinite loop.
+
+### Fix #3: reply-token cache + Push fallback
+
+Real LINE adapter changes (when wired). Sketch:
+
+```python
+# backend/app/adapters/line/real.py
+
+class LineRealAdapter:
+    def __init__(self, channel_secret, channel_access_token, ...):
+        ...
+        self._reply_tokens: dict[str, tuple[str, float]] = {}  # chat_id → (token, expiry)
+        # fetch bot user-id at register-time, set self._bot_user_id
+
+    async def send_reply(self, line_user_id, text):
+        text = strip_markdown_preserving_urls(text)
+        chunks = split_for_line(text, max_chars=4500)[:5]
+        ...
+        # try reply token first (cache from last inbound msg), fall back to push
+```
+
+When wiring is real, this is non-trivial (~40 lines + the dispatcher in `lead_pipeline` would need to write the reply_token onto a row). Today's mock can stub it.
+
+### Fix #4: chunking helper
+
+```python
+# backend/app/adapters/line/base.py (shared helpers)
+
+MAX_MESSAGES_PER_CALL = 5
+LINE_SAFE_BUBBLE_CHARS = 4500
+
+def split_for_line(text: str, max_chars: int = LINE_SAFE_BUBBLE_CHARS) -> list[str]:
+    """Naive chunk: prefer paragraph, then sentence, then char."""
+    if len(text) <= max_chars:
+        return [text]
+    # ...paragraph / sentence / char fallback...
+    return chunks[:MAX_MESSAGES_PER_CALL]
+```
+
+~15 lines. Add to `line/base.py` so both mock and real get it.
+
+### Fix #5: `unsend` event handling
+
+Small but real. In `lead_pipeline.py::process_event`:
+
+```python
+if event.get("type") != "message":
+    return ProcessResult(..., reason="non_message")
+
+# Add: type-specific routing
+msg = event.get("message") or {}
+if msg.get("type") == "unsend":
+    mark_withdrawn(msg.get("id"), db)  # store the redacted note; UI can hide later
+    return ProcessResult(..., reason="unsend")
+
+# existing text / lead creation...
+```
+
+Requires adding an `is_withdrawn` column to `messages` (one migration) and a column to the schema python mirror. Defer unless users ask.
+
+---
+
+## Verdict + suggested action
+
+If we want to land **only the high-leverage fixes**, the smallest coherent PR would:
+
+1. **Body size cap** (3-5 lines)
+2. **`unsend` event graceful handling** (defer; this PR nothing)
+3. **Markdown strip + chunking helpers added to `line/base.py`** (used by future real adapter; tested via unit test on a mock that exercises chunking boundaries; 30 lines + tests)
+4. **Self-message filter stub** (5 lines in real adapter — exercises the path even on mock)
+
+That's ~50 lines of code + ~20 lines of tests. The reply-token cache + Push fallback is the only medium piece; it goes in **only when we wire the real adapter** because the mock already covers "send a reply" semantics.
+
+I'd tag the rest of the table above (allowlists, media inbound, media send, loading indicator, webhook port env, public URL env, slow-LLM button, account link, things, memberJoined/Left) as **future AIDLC tickets** that will surface when users ask for them. None of them is blocking today's MVP demo.
+
+---
+
+## TL;DR for the PR description
+
+> Reviewed [hermes-agent#23197](https://github.com/NousResearch/hermes-agent/pull/23197) to mine for patterns relevant to our mocks-first Thai real-estate LINE integration. We're going to fold 4 small security/correctness items into the next backend PR (body-size cap, markdown strip + LINE chunking helpers in `line/base.py`, self-message filter stub on the real adapter, and a graceful `unsend` handler in `lead_pipeline`). Reply-token cache + Push fallback is the one substantive real adapter work; we'll add it when we wire the real client because the mock already covers the semantics. Everything else (allowlists, media, slow-LLM button, account-link, things) is N/A or future-work — flagged as AIDLC tickets.

Applies all 4 P0 findings from the PR #2 review. C1+C2 are the load-bearing
ones; C3+C4 are doc/comment accuracy.

## C1 — Mock applies the same outbound transforms as the real adapter

Previously LineMockAdapter.send_reply recorded text verbatim.
When real wiring lands and the real adapter strips **bold, headings,
code fences, etc.** + chunks at the 5-message cap, mock and real
diverge on what LINE would actually receive.

The mock now mirrors the real adapter's outbound path:

  strip_markdown(text) \u2192 split_for_line(cleaned) \u2192 record each chunk
  with chunk_index 0..N-1.

Tests in test_line_helpers.py::TestLineMockAdapterOutboundParity
verify that **bold / *italic* are stripped, long text is chunked, and
the chunk count respects LINE_MAX_MESSAGES_PER_CALL=5.

Reply-token routing: tokens are single-use. The mock now consumes the
token on first send_reply so a second send to the same chat falls
back to push (matching real behavior). Tests verify mode='reply'
on the first call and mode='push' on the second.

## C2 \u2014 Reply-token cache + bot_user_id live on the Protocol

Previously the bones sat only on LineRealAdapter and the webhook
couldn't reach them without an isinstance() check \u2014 breaking the
4-adapter contract ("no router imports a concrete class by name").

Both bot_user_id and set_reply_token(chat_id, token) are now
on the LineAdapter Protocol. Both the mock and the real adapter
implement them. The webhook takes a LineDep and calls
line.set_reply_token(chat_id, reply_token) on every inbound
message event with a replyToken field.

The router has a new _cache_reply_token helper that:

  - Reads replyToken from the event
  - Resolves chat_id from source.userId / groupId / roomId
  - Silently skips when neither is set (defensive against malformed events)

Tests in test_line_webhook.py cover:

  - Inbound message with replyToken \u2192 cache populated
  - Inbound follow/unfollow/etc. \u2192 cache stays empty (no replyToken)
  - set_reply_token consumes on first send_reply (Reply mode)
  - Second send_reply without re-caching falls back to Push (mode='push')

The TTL constant REPLY_TOKEN_TTL_SECONDS = 60 was moved from
real.py to base.py so the mock and real share it.

## C3 \u2014 Doc lies

Two doc lies fixed:

- TL;DR table at the top of docs/line-integration-gap-analysis.md
  marked unsend event handling as **"Fix in this PR"** \u2014 it
  wasn't. Now correctly marked **"Defer (1-migration scope; not in
  this PR)"**.

- The "TL;DR for the PR description" block listed unsend as one
  of the 4 things shipped \u2014 it wasn't. Now lists the actual 4
  (body-cap, transforms, self-message + reply-token, LineDep wiring).

The "Verdict + suggested action" section (line 239) already said
"defer" correctly; only the two stale bits are now consistent with it.

## C4 \u2014 aiohttp comment was a copy-paste from hermes-agent

backend/app/routers/line_webhook.py:33 had a comment claiming
"aiohttp's client_max_size doesn't apply in all body modes". This
project uses FastAPI + Starlette + uvicorn, NOT aiohttp \u2014 the
reference was a copy-paste from the source PR.

Rewrote the comment to reference Starlette's Request.body() and
mention uvicorn's h11_max_incomplete_event_size for nginx-fronted
deployments. The 1 MiB cap (line 41) is now correctly described as
memory-exhaustion defence for Starlette's unbounded buffer.

## Verified

- pytest: 184/184 (was 168; +16 new) \u2014 coverage 92.99% \u2265 80% \u2705
- RUN_REAL_ADAPTER_TESTS=1: 6/6 \u2705 (Protocol conformance still
  holds after bones promotion; isinstance(LineRealAdapter,
  LineAdapter) + isinstance(LineMockAdapter, LineAdapter) both
  return True)
- ruff + mypy strict: clean

## Out of scope

- strip_markdown leaks content from code spans (Backend warning) \u2014
  noted, follow-up
- _MD_ITALIC_STAR matches arithmetic (Backend warning) \u2014 noted,
  follow-up
- self-message filter default-off (Backend warning) \u2014 real wiring
  must set bot_user_id; documented
- chat_id / line_user_id reconciliation \u2014 currently same in DMs;
  groups deferred to when we add group support
- unsend event handling \u2014 1-migration, deferred (correctly noted in
  C3 fix)

-> Reviewed [hermes-agent#23197](https://github.com/NousResearch/hermes-agent/pull/23197) to mine for patterns relevant to our mocks-first Thai real-estate LINE integration. We're going to fold 4 small security/correctness items into the next backend PR (body-size cap, markdown strip + LINE chunking helpers in `line/base.py`, self-message filter stub on the real adapter, and a graceful `unsend` handler in `lead_pipeline`). Reply-token cache + Push fallback is the one substantive real adapter work; we'll add it when we wire the real client because the mock already covers the semantics. Everything else (allowlists, media, slow-LLM button, account-link, things) is N/A or future-work — flagged as AIDLC tickets.

Subject: [PATCH 22/22] fix(line): deduplicate REPLY_TOKEN_TTL_SECONDS
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The P0 fix on the previous commit added REPLY_TOKEN_TTL_SECONDS to
app.adapters.line.base, but left the same constant re-defined in
app.adapters.line.real (line 25-27). Behavior was correct (both
values are 60) but the dedup wasn't actually a dedup — real.py
imported nothing from base for the constant.

Removes the local definition in real.py and adds the constant to
the existing import block from base. No behavior change.
