f051fe3162 feat(realtime): monitoramento em tempo real via WebSocket multi-tenant
Fecha agente.md secao 54-55 (infraestrutura) e 161 (WebSocket multi-tenant).
Entrega o pipeline de push em tempo real completo — o consumo visual
("Monitoramento -> Filas/Ramais") fica pra fase Frontend.

Requisito central da secao 161 ("nao transmitir tudo e filtrar so no
browser"): RealtimeGateway tem um unico ponto de emissao,
broadcastToTenant(), sempre server.to(`tenant:<id>`), nunca broadcast
global. Cada socket entra na room do proprio tenant no handshake, nunca
escolhe a room.

Autenticacao na conexao (handshake.auth.token, nao Authorization header):
valida o JWT (mesmo verifyAccessToken do JwtAuthGuard), exige tenantId no
token e a permission monitoring.view (ja existia desde RBAC, sem
consumidor ate agora) — mesmo principio de nunca confiar em tenant_id do
client, so do JWT ja emitido por /auth/select-tenant.

Origem dos eventos: canal Redis unico b2bcall:events (o mesmo desde Event
Socket). Dois produtores: b2bcall-fs-events (eventos do FreeSWITCH,
resolvendo tenantId por fan-out quando nao ha channel variable, ver
tenant-resolve.ts) e apps/api (mudancas no nosso Agent.state via
agents-me.controller, tenantId direto do JWT, sem fan-out).

Bug real achado e corrigido ao construir esta fase: nenhum evento CUSTOM do
ESL (sofia::register, sofia::gateway_state, callcenter::info) jamais
chegava em b2bcall-fs-events nesta sessao inteira. Causa: event_json(...)
mandava "CUSTOM" como ultimo token do comando `event json`, sem subclass
depois — mod_event_socket exige os subclasses logo depois do token CUSTOM
no mesmo comando pra serem entregues. Corrigido separando PLAIN_EVENTS
(viram listener .on()) de CUSTOM_SUBCLASSES (so compoem o comando de
assinatura). Resolve as lacunas ja documentadas em docs/TRUNKS.md e
docs/AGENTS.md. De quebra, corrigido um bug de nome de campo
(CC-Agent-Status, que nao existe -> CC-Agent-State) e um segundo bug real
em trunk-sync.ts (rescan nunca descarregava gateway removido -> agora roda
`killgw` antes do rescan).

Novos tipos normalizados a partir de callcenter::info, com nomes de campo
confirmados contra uma fila real: AGENT_OFFERED_CALL, AGENT_BRIDGE_FAILED,
QUEUE_MEMBER_COUNT (chamadas esperando, secao 54), QUEUE_MEMBER_LEFT (com
cause/cancelReason e timestamps — base pra Service Level/Abandon Rate
quando CDR existir).

Verificado ponta a ponta com um client socket.io real: login/pause/resume/
logout emitindo AGENT_STATE_CHANGED; chamada de teste numa fila com agente
logado emitindo QUEUE_MEMBER_COUNT/LEFT, AGENT_OFFERED_CALL,
AGENT_BRIDGE_FAILED, AGENT_STATUS_CHANGED (CC-Agent-State correto); token
ausente/invalido desconectado na hora, sem vazar nenhum evento.

Achado sistemico durante o teste (documentado, nao corrigido nesta fase):
@@unique combinado com soft delete, sem excluir deletedAt, em
Agent/Extension/Trunk/Queue/PauseReason — nao da pra reusar numero/nome/
codigo depois de apagar. Precisa de indice unico parcial em cada um, fora
do escopo desta fase.

typecheck do workspace inteiro limpo. ~144MB de memoria total nos
containers (fs-events 44MB, fs-config 45MB, freeswitch 26MB, postgres
21MB, redis 8MB).

a05104a05f feat(agents): agentes, tiers e pausas — call center completo
Fecha agente.md secao 45-49/52. Depois desta fase, um usuario autenticado
consegue logar como agente, entrar numa fila real, se pausar e voltar,
tudo refletido de verdade no FreeSWITCH.

Schema (migration 20260828124245_agents):
- agents (tenant-scoped, RLS): User -> Extension -> identidade de agente,
  state (enum AgentState de 8 valores) espelhando o estado real, so
  alterado via login/logout/pause/resume, nunca escrito direto pela API.
- tiers: Queue<->Agent (level/position 1:1 com mod_callcenter).
- agent_sessions: um ciclo login->logout por linha.
- agent_state_events: historico de transicoes de estado.
- pause_reasons / agent_pause_events (secao 48).

Dois bugs reais corrigidos em FreeSwitchTelephonyProvider, presentes desde
a fase de Event Socket original:
- "queue add/del member" nao existe no mod_callcenter — membership de
  fila usa tier add/tier del. So foi pego agora ao confirmar de novo a
  sintaxe via `help callcenter_config` antes de codar esta fase.
- addAgent/removeAgent nao existiam ainda (agent add/del).

Mecanismo de sync: agentes e tiers nao tem representacao em XML, so
comando ESL direto — diferente do padrao "regenera todos os arquivos"
usado em Trunks/Queues. apps/api publica uma mensagem por acao com
payload (b2bcall:agents:sync, b2bcall:tiers:sync); b2bcall-fs-config
aplica o comando correspondente (agent-sync.ts).

Achados confirmados manualmente contra o FreeSWITCH real antes de codar:
- `agent add`/`tier add` nao sao idempotentes (erro em duplicata) — sync
  ignora esse erro (.catch), condicao esperada em resync.
- `agent del`/`tier del` em algo inexistente nao da erro — seguro chamar
  sem checar existencia antes.
- `agent set status` so aceita 3 valores exatos (Available/On Break/
  Logged Out) — testado deliberadamente com valor invalido.
- Corrida real: atribuir tier antes do primeiro login do agente falha
  silenciosamente do lado do FreeSWITCH (agente so existe la a partir do
  `agent add` no login). Login sempre re-sincroniza todos os tiers do
  agente depois de garantir que ele existe — auto-correcao confirmada no
  teste ponta a ponta.

apps/api: AgentsController (CRUD), AgentsMeController (login/logout/
pause/resume — sempre resolve o agente via JWT, nunca um agentId
arbitrario do client), PauseReasonsController (CRUD), QueueAgentsController
(POST/DELETE de tier em /queues/:id/agents).

Verificado ponta a ponta via curl + fs_cli contra o FreeSWITCH real:
login -> Available, pause -> On Break, resume -> Available, logout ->
Logged Out, todos batendo entre Agent.state (banco) e `agent list`
(FreeSWITCH). typecheck do workspace inteiro limpo. ~350MB de memoria
total (docker stats).

Documentado em docs/AGENTS.md, incluindo lacuna conhecida: estados
derivados de chamada (RINGING/IN_CALL/WRAP_UP/RESERVED) dependem do
evento CUSTOM callcenter::info, ainda nao comprovado chegando em
fs-events nesta sessao (mesma lacuna de sofia::gateway_state ja
documentada em docs/TRUNKS.md) — precisa de uma chamada real passando
pela fila pra investigar.

6628578c42 feat: implement Call Center queues (mod_callcenter)
- Investigated the real callcenter_config command surface via
  'help callcenter_config' on the running FreeSWITCH before writing any
  code: queues only have load/unload/reload (static XML + reload, no
  'queue add' exists), while agents and tiers are fully dynamic via ESL
  commands (agent add, tier add) -- no file involved. This shapes the next
  phase (Agents/Tiers) differently from this one.
- queues table (tenant-scoped, RLS): strategy, moh/announce, wait times,
  tier rules, discard/abandoned handling, skip-agents-with-external-calls,
  recording_enabled
- packages/telephony: buildQueueXml()
- infrastructure/freeswitch: our own callcenter.conf.xml override (empties
  the vanilla static agents/tiers -- those become fully dynamic in the next
  phase) that includes callcenter_queues.conf.d/*.xml via X-PRE-PROCESS,
  same pattern as the Sofia gateway directory
- apps/api/src/queues: CRUD (POST/GET/GET:id/DELETE) using the queues.view/
  .manage permissions already in the seed
- b2bcall-fs-config (queue-sync.ts): one XML file per queue on a shared
  volume, synced via Redis pub/sub (b2bcall:queues:sync) on create/delete
  and once at boot -- same shape as trunk-sync.ts
- confirmed manually against the real FreeSWITCH, before coding the sync
  logic: 'queue load <name>' fails ('Invalid Queue not found!') for a file
  added after boot -- needs 'reloadxml' first to repopulate the in-memory
  XML tree from disk; after that, 'queue reload <name>' alone handles both
  create and update, no need to distinguish load vs reload
- verified end-to-end: created a queue (ROUND_ROBIN, maxWaitTime=120,
  discardAbandonedAfter=90), 'callcenter_config queue list' showed the
  correct values on the FreeSWITCH side; deleted it, list went back empty

0720a0efe3 feat: implement Dialplan with structured editor and versioning
- dialplan_extensions table (tenant-scoped, RLS): structured editor per
  agente.md secao 43 -- context, condition field/expr, actions/anti-actions
  (JSON), continue, order, enabled. One condition per extension (deliberate
  simplification vs raw FreeSWITCH's multi-condition extensions).
- dialplan_versions table (tenant-scoped, RLS): generate/validate/version/
  activate flow (secao 44). Reactivating an older version IS the rollback
  mechanism -- no separate endpoint needed.
- apps/api/src/dialplan: extensions CRUD + versions/generate (builds XML,
  validates well-formedness with fast-xml-parser, saves as DRAFT) +
  versions/:id/activate (atomically flips ACTIVE, supersedes the previous
  one). Reused freeswitch.view/.configure permissions rather than inventing
  new ones not in the agente.md permission list.
- packages/telephony: buildDialplanXml() plus ALLOWED_DIALPLAN_APPLICATIONS,
  an explicit allowlist (answer/bridge/playback/hangup/set/export/... --
  deliberately no system/exec/socket) guarding against a tenant configuring
  a dialplan action that runs arbitrary commands on the FreeSWITCH host
  (agente.md secao 180)
- b2bcall-fs-config resolves dialplan dynamically per call (unlike Trunks'
  file+rescan approach -- dialplan is fetched fresh via mod_xml_curl on
  every call anyway) by tenant id from the variable_b2bcall_tenant_id
  channel variable already injected at directory resolution, then serving
  whichever DialplanVersion is ACTIVE for that context
- verified end-to-end: created a rule for destination_number 7000, generated
  and activated v1, originated a call that actually routed through the
  dialplan (not bypassing it via &app()) -- CALL_CREATED -> CALL_ANSWERED ->
  CALL_ENDED with the correct tenantId throughout. Created and activated a
  v2, then rolled back to v1 by reactivating it; status transitions
  (ACTIVE/SUPERSEDED) all confirmed via the API.

CRITICAL FINDING, fixed in this same phase: deliberately testing that the
application allowlist rejects 'system' got back 201 instead of 400 --
NestJS's ValidationPipe had been silently inert across all of apps/api's
@Body() DTOs since the API was first created. Root cause: running via
 (esbuild) instead of a real  build -- esbuild doesn't always
resolve cross-file parameter types for design:paramtypes metadata, and Nest
skips validation without any error when it can't determine the DTO class.
Fixed by always building with tsc before running (tsc && tsx dist/main.js
-- still via tsx because internal workspace packages aren't built to JS
yet). Re-verified with two deliberate bad-input tests post-fix, both
correctly rejected with 400. A stray malicious test row (dialplan action
'system') created while the bug was live was deleted; it was never baked
into an activated version, so nothing could have executed it.
See docs/VALIDATION_PIPE_BUG.md for the full writeup.

4c638ad496 feat: implement Trunks with real FreeSWITCH gateway sync
- trunks table (tenant-scoped, RLS): host/proxy/realm, register,
  username/password_enc (AES-256-GCM), dtmf_mode, ping, transport, and a
  status/status_updated_at pair meant to be driven by FreeSWITCH events
- apps/api/src/trunks: CRUD (POST/GET/GET:id/DELETE), same RBAC/tenant
  pattern as Extensions, password never exposed in any GET
- packages/telephony: buildGatewayXml() generates a Sofia gateway XML file
- b2bcall-fs-config now writes sip_profiles/external/<trunk_id>.xml (shared
  Docker volume with FreeSWITCH -- the vanilla external profile already
  includes external/*.xml) and runs 'sofia profile external rescan' over
  ESL; syncs on boot and on demand via Redis pub/sub
  (b2bcall:trunks:sync), since apps/api runs on the host and fs-config has
  no port published to reach directly
- added FreeSwitchTelephonyProvider.waitUntilConnected() to fix a startup
  race: the first sync ran before the ESL connection had settled, logging
  a harmless but noisy error
- verified end-to-end with a fake host: create trunk -> gateway file
  written -> FreeSWITCH shows the real gateway (FAIL_WAIT, expected) ->
  delete -> file removed (cleanup also correctly swept the stale
  'example.com' gateway that had been copied into the volume from the
  vanilla image)
- apps/freeswitch-events/src/trunk-status.ts: written to update Trunk.status
  from sofia::gateway_state events, using the same normalizeEslEvent path
  already proven for CHANNEL_* events

- KNOWN GAP, documented rather than glossed over: monitored fs-events for
  ~90s while the gateway visibly transitioned states in FreeSWITCH
  (FAIL_WAIT/DOWN) and no sofia::gateway_state event was observed arriving.
  CUSTOM/sofia::* events have not actually been proven working end-to-end
  in this session -- only CHANNEL_* events have been. Needs verification
  against a real SIP target before the status auto-update can be trusted
  in production. See docs/TRUNKS.md and TODO.md.

c03c6d4eaa feat: implement Extensions with real FreeSWITCH directory integration
- extensions table (tenant-scoped, RLS): number, sip_password_enc
  (AES-256-GCM via packages/shared/src/crypto.ts), caller_id, context,
  sofia_profile, codecs, max_registrations
- apps/api/src/extensions: CRUD (POST/GET/GET:id/DELETE), protected by a
  new generic PermissionGuard (@RequirePermission decorator), tenant
  resolved only from the JWT (never trusted from the client)
- SIP password is returned in plaintext only once, in the create response;
  toPublicExtension() explicitly destructures the encrypted field out
  (not a spread) so it can't leak by accident
- b2bcall-fs-config now resolves real directory data: Tenant.telephonyDomain
  -> Extension.number, decrypts the password, builds proper directory XML
  including a dial-string param (missing it caused originate to fail with
  MANDATORY_IE_MISSING instead of the expected USER_NOT_REGISTERED)
- pinned FreeSWITCH's 357737{domain} to a stable value (b2bcall.local) via a
  vars.xml patch in the Dockerfile -- it previously used the container's
  dynamic IP, which could never match a stored telephony_domain
- added HTTP Basic auth between FreeSWITCH and fs-config
  (gateway-credentials, timingSafeEqual comparison) now that the service
  returns real secret data, closing the gap flagged as pending in the XML
  Curl phase instead of leaving it open
- found and fixed: PermissionGuard's constructor-injected Reflector came
  back undefined at runtime under tsx/esbuild (unreliable cross-file
  decorator metadata emission) -- fixed with an explicit @Inject(Reflector);
  worth watching for in future guards/services run via tsx
- verified end-to-end: create extension -> originate user/<ext> reports
  USER_NOT_REGISTERED (found, not registered) -> delete -> back to
  SUBSCRIBER_ABSENT (not found); password never reappears in any GET;
  unauthenticated fs-config requests get 401

d2ea83c06a feat: activate mod_xml_curl with b2bcall-fs-config (agente.md secao 26)
- apps/freeswitch-config (b2bcall-fs-config): Fastify service implementing
  the mod_xml_curl HTTP protocol (form-encoded POST -> XML response),
  containerized, no host port published
- reactivated mod_xml_curl in FreeSWITCH, binding restricted to
  directory|dialplan only (configuration was removed after testing showed
  it firing several unnecessary HTTP round-trips at boot for module
  configs we don't need dynamic — matches agente.md's own 'don't put every
  critical config through XML Curl' guidance)
- no extensions/dialplan tables exist yet (next phases), so the service
  always answers 'not found' for now — this phase only proves the wire
  protocol works without breaking the static vanilla config fallback
- verified end-to-end: user/8888 (nowhere) -> SUBSCRIBER_ABSENT via
  fs-config; user/1000 (static vanilla extension) -> USER_NOT_REGISTERED,
  proving FreeSWITCH correctly falls through to static XML when xml_curl
  says not found
- docs/XML_CURL.md, including the not-yet-authenticated endpoint note (fine
  while it only returns not-found; needs gateway-credentials before serving
  real directory/dialplan data)
2026-08-28 07:07:05 -03:00
60e9f6838e feat: add Event Socket integration (b2bcall-fs-events)
- packages/telephony: TelephonyProvider interface (agente.md secao 25) and
  FreeSwitchTelephonyProvider implementation over the 'esl' library
  (actively maintained, TypeScript-native, built-in reconnect-with-backoff
  satisfying secao 195); normalizeEslEvent() translates raw ESL events into
  the internal vocabulary (secao 24)
- apps/freeswitch-events (b2bcall-fs-events): permanent ESL connection,
  resubscribes on every reconnect, publishes normalized events to the
  'b2bcall:events' Redis pub/sub channel; containerized (Dockerfile +
  docker-compose service) since its whole job is reaching the freeswitch
  container by internal hostname
- packages/shared: reusable createLogger() (structured JSON per secao 189),
  fixed a BigInt serialization crash surfaced by the esl library's error
  stats
- found and fixed a real FreeSWITCH 1.11 default: without an explicit
  apply-inbound-acl, mod_event_socket silently rejects any non-loopback
  connection ('Access Denied, go away.') even with the correct password —
  added a dedicated ACL (loopback + the Docker Compose network range, never
  0.0.0.0/0) in infrastructure/freeswitch/overrides/autoload_configs/
- verified end-to-end with a local loopback test call: CALL_CREATED ->
  CALL_ANSWERED -> CALL_ENDED observed on the Redis channel with the
  correct callUuid and hangup cause
- docs/EVENT_SOCKET.md
2026-08-28 06:47:28 -03:00
b3b0aaacb3 feat: add FreeSWITCH service (SignalWire packages, not compiled from source)
- infrastructure/freeswitch/Dockerfile: debian:trixie-slim + SignalWire
  packaged freeswitch-meta-vanilla, avoiding a C/C++ build on a 1.9GB RAM VM
- FREESWITCH_PAT used only via Docker BuildKit secret, apt credentials file
  created and deleted within the same RUN — verified absent from the final
  image with docker history
- minimal module set (agente.md secao 15): sofia, event_socket, commands,
  dptools, callcenter, avmd, curl, local_stream, etc. mod_xml_curl installed
  but disabled — it refuses to load without a configured gateway-url, which
  will exist once b2bcall-fs-config is built
- entrypoint.sh rotates the Event Socket password away from the 'ClueCon'
  default at container runtime (never baked into the image); fails loudly if
  ESL_PASSWORD is unset
- port 8021 not published to the host; only reachable from other containers
  on the compose network
- found and fixed: freeswitch-conf-vanilla is a Recommends (not a Depends)
  of freeswitch-meta-vanilla, so --no-install-recommends silently produced
  an empty /etc/freeswitch and a crash loop
- verified end-to-end: fs_cli status via ESL with the custom password,
  default password rejected, expected modules loaded, healthcheck green,
  ~44MB RAM usage
- docs/FREESWITCH.md, docs/NETWORK_ARCHITECTURE.md (network_mode decision
  deferred until a real SIP trunk exists)
2026-08-28 06:30:25 -03:00
68b403a7ff feat: add apps/api (NestJS + Fastify) with authentication endpoints
- POST /auth/login, /auth/refresh, /auth/logout, /auth/select-tenant,
  /auth/change-password, GET /auth/tenants — wired to packages/auth
- JwtAuthGuard + DomainExceptionFilter (401/403 without leaking internals)
- LoginRateLimitGuard: Redis-backed 5/min per IP and per email (agente.md
  secao 149), safe across multiple API instances
- helmet + restrictive cors (deny-by-default) + global rate limit
- GET /health, /health/live, /health/ready checking Postgres and Redis
- changePassword() added to packages/auth for the mustChangePassword flow
- fixed REDIS_HOST/POSTGRES_HOST docker-compose-only hostnames not
  resolving from the host process; added REDIS_URL for host-side use
- verified end-to-end with curl: login, wrong password / unknown email
  (same generic error), authenticated route, missing token, refresh
  rotation, logout revocation, and the 429 rate limit kicking in after 5
  attempts
2026-08-28 06:12:34 -03:00
70c5586595 feat: implement authentication and RBAC
- packages/auth: Argon2id password hashing, JWT access tokens (jose),
  opaque refresh tokens with rotation, generic error messages (no
  user-enumeration via timing or message differences)
- roles/permissions/role_permissions/user_roles/sessions/audit_logs schema
  (agente.md secoes 142-150); RBAC scope PLATFORM vs TENANT
- withUserContext(): narrow RLS exception so a user can discover their own
  tenant_memberships before a tenant is chosen (login flow)
- userHasPermission()/isPlatformUser(): explicit service-layer RBAC checks
  (roles/permissions tables are not RLS-protected — documented why in
  docs/AUTHENTICATION.md)
- seed: permission catalog, 4 system roles, initial Platform Super Admin
  (password written once to FIRST_LOGIN.txt, 600, outside Git)
- automated end-to-end test: login, RBAC check, refresh rotation, logout
2026-08-28 05:58:49 -03:00
d66170c795 feat: implement tenant isolation with PostgreSQL RLS
- users + tenant_memberships tables (tenant-scoped)
- RLS policy on tenant_memberships using set_config('app.current_tenant_id', ...)
- withTenantContext() helper for transaction-scoped tenant context
- separate non-superuser app role (b2bcall_app): the default Docker postgres
  user is SUPERUSER and always bypasses RLS even with FORCE, so the app must
  never connect through the migration/owner role. Documented in
  docs/TENANT_ISOLATION.md.
- automated isolation test proving tenant A never sees tenant B's data
