…ltiplex profiles

Fix NousResearch#75349

Root cause:
Under multiplex_profiles, secondary profiles run inside
_profile_runtime_scope which installs a per-profile secret scope via
set_secret_scope.  The WhatsApp adapter (and the shared
WhatsAppBehaviorMixin + Cloud API adapter) read WHATSAPP_MODE,
WHATSAPP_DM_POLICY, etc. via raw os.getenv(), bypassing the secret
scope.  Since os.environ doesn't contain secondary profile .env values,
the bridge silently falls back to 'self-chat' and rejects all inbound
messages with self_chat_mode_rejects_non_self.

Fix:
- Add _wenv() helper in adapter.py that reads WHATSAPP_* vars through
  get_secret() (agent.secret_scope), which honors the active scope.
- Replace all os.getenv('WHATSAPP_*') calls in adapter.py,
  whatsapp_common.py, and whatsapp_cloud.py with get_secret()-based
  equivalents.
- Inject resolved WHATSAPP_* values into the bridge subprocess
  environment so the Node.js bridge (which reads process.env) sees the
  profile's own configuration.

Changes:
- plugins/platforms/whatsapp/adapter.py: 37 lines (+ helper, bridge_env
  injection, 2 os.getenv→_wenv)
- gateway/platforms/whatsapp_common.py: 13 lines (6 os.getenv→_get_wsecret)
- gateway/platforms/whatsapp_cloud.py: 21 lines (9 os.getenv→_get_wsecret)
- New regression test: 6 test cases covering scope isolation, fallback,
  and cross-profile non-leakage.

Thanks for tracing the multiplex secret-scope boundary; the core diagnosis is correct. Current main reads WHATSAPP_MODE via os.getenv before spawning the bridge (plugins/platforms/whatsapp/adapter.py:634), while multiplex scopes intentionally keep profile .env values out of os.environ (agent/secret_scope.py:123-177).

Problems

  • The new child-environment overlay is incomplete. scripts/whatsapp-bridge/bridge.js:56-124 also reads WHATSAPP_DEBUG, WHATSAPP_FORWARD_OWNER_MESSAGES, WHATSAPP_REPLY_PREFIX, WHATSAPP_MAX_MESSAGE_LENGTH, WHATSAPP_CHUNK_DELAY_MS, and WHATSAPP_SEND_TIMEOUT_MS; these remain process-global for secondary profiles. Please scope and forward the bridge's complete WHATSAPP_* input set.
  • The secondary startup guard is still unscoped: _start_one_profile_adapters() leaves _profile_runtime_scope before _own_policy_open_startup_violation() (gateway/run.py:12520-12522), whose policy reads use os.getenv (gateway/run.py:2269-2284). This can validate different policy values than the adapter uses after this change.

Suggested changes

  • Add a mocked connect() regression test asserting Popen(..., env=...) receives scoped mode, allowlist, and an additional bridge-only setting.
  • Evaluate the startup access-policy guard through the profile secret scope.

Automated hermes-sweeper review.

_profile_wa_mode = _wenv("WHATSAPP_MODE", "self-chat")
if _profile_wa_mode != "self-chat" or _profile_wa_mode:
bridge_env["WHATSAPP_MODE"] = _profile_wa_mode

Please forward the complete scoped environment contract consumed by scripts/whatsapp-bridge/bridge.js, not only this subset. The bridge also reads WHATSAPP_REPLY_PREFIX, WHATSAPP_FORWARD_OWNER_MESSAGES, WHATSAPP_DEBUG, WHATSAPP_MAX_MESSAGE_LENGTH, WHATSAPP_CHUNK_DELAY_MS, and WHATSAPP_SEND_TIMEOUT_MS; otherwise secondary profiles still silently fall back to process-global/default behavior for those settings.

fix(whatsapp): default-profile UnscopedSecretError fallback + full br…
3d51d21 
…idge env set

Follow-ups on the #75382 salvage (review findings):
- _wenv/_get_wsecret now catch UnscopedSecretError and fall back to
  os.getenv for the DEFAULT profile's adapter, which constructs and sends
  outside any _profile_runtime_scope under multiplexing — a bare
  get_secret would crash its WhatsApp path (fixing one profile by
  breaking another). Same pattern as Slack SLACK_APP_TOKEN (#59739) and
  the Matrix recovery key. Scoped misses still return the default — no
  cross-profile borrow.
- bridge_env overlay extended to the full WHATSAPP_* set bridge.js
  consumes (DEBUG, FORWARD_OWNER_MESSAGES, REPLY_PREFIX,
  MAX_MESSAGE_LENGTH, CHUNK_DELAY_MS, SEND_TIMEOUT_MS).
- Removed the always-true conditional on WHATSAPP_MODE injection.

Salvaged and merged in #76573 — your substantive commit is on main as 4f4ea9a with your authorship, closing #75349 (the CI-retrigger and stray-changelog commits were dropped in salvage). We added follow-ups (5438e9c) for the review findings: an UnscopedSecretError→os.getenv fallback in _wenv/get_wsecret so the DEFAULT profile's adapter (which runs unscoped under multiplexing) doesn't crash — the Slack #59739 pattern; the bridge_env overlay extended to the full WHATSAPP* set bridge.js consumes; and the always-true WHATSAPP_MODE conditional removed. During rebase we also routed main's new allowlist-precedence reads through your scoped helpers, so that feature is multiplex-safe too. Thanks @x7peeps!

✅ Resolved on main

PR has been closed. The review feedback was addressed on upstream main via commit 5438e9c629 which forwards the complete set of WHATSAPP_* environment variables consumed by scripts/whatsapp-bridge/bridge.py through the secret scope.

No further action needed on this PR.
