fix(gateway): classify real token locks and keep lifecycle running

[alexgunsberg]

Bug Description

Optional platform startup auth/config failures (production: Buzz relay_membership_required) previously forced gateway exit 78 and stopped scheduler/Kanban. PR #83161 tried to isolate them but was closed after independent BLOCK: production token-lock conflicts are emitted retryable=True and bypassed the fatal classifier, and gateway_state=degraded is neither busy nor drainable.

Root Cause

1. BasePlatformAdapter._acquire_platform_lock marks live foreign holders retryable=True (for later reconnect). Startup routed solely on that flag, so pure single-writer conflicts stayed alive / retry-queued instead of exit 78.
2. Multiplex secondary lock failures were logged and disconnected without feeding the fatal classifier.
3. Persisting lifecycle degraded breaks derive_gateway_busy / derive_gateway_drainable (only running is drainable).

Fix

• Add is_global_startup_conflict() and classify lock/polling ownership before generic retry routing.
• Pure global conflicts at zero-connected startup → exit 78; never retry-queue them at startup.
• Secondary multiplex lock failures use the same classifier.
• Platform-local auth/config (Buzz membership, missing credentials) parks fatal per-platform; gateway stays alive for cron/Kanban/healthy peers.
• Lifecycle stays running; per-platform fatal/retrying holds detail (no non-drainable degraded lifecycle).

Test Plan

• Real foreign lock-holder via production _acquire_platform_lock (retryable=True) exits 78, not retry-queued
• Secondary multiplex token-lock exits 78
• Buzz-style platform-local auth parks fatal; lifecycle running; Kanban watchers spawn; busy/drain true with active_agents
• Healthy peer continues when optional adapter fails
• NS-609 mixed retryable + local nonretryable stays alive
• Adapter-level lock remains retryable for post-startup reconnect (Bug: Stale Telegram bot token lock permanently kills platform (retryable=False in _acquire_platform_lock) #54167)
• Existing fatal/reconnect/lock/status/multiplex tests + Ruff pass

Risk Assessment

Low–medium. Narrow startup classification change; pure lock conflicts and multiplex config errors keep exit-78; optional platforms no longer take down duties; lifecycle busy/drain preserved.

Notes

• Supersedes closed fix(gateway): isolate optional platform auth failures from exit 78 #83161 (branch preserved). Do not deploy before independent exact-head review PASS.
• Exact tested SHA: will match PR head after create.

Independent exact-head review: CHANGES REQUIRED

Reviewed head: 5a44eb7

Three HIGH findings:

1. gateway/run.py: secondary retryable startup failures can suppress exit 78 without entering any retry registry, leaving a live but deaf gateway.
2. gateway/restart.py: telegram_connect_error does not inspect the production 409 polling-conflict message, so a duplicate poller remains on the generic retry path.
3. Buzz/IRC/LINE adapters treat acquire_scoped_lock()'s (False, existing) tuple as truthy, making lock-conflict branches unreachable.

Do not merge or deploy this head. Repair the three findings, add production-shape regressions, rerun focused gateway/status suites, and request a fresh exact-head review.

HIGH-3 residual repair at exact head

Head: 8983942625ebf6dbaf3ab28c9109c977d4a13944
(previous: 5a44eb7647d42a11f831203df8e0a0f123346b96)

Repairs the three independent-review HIGH findings only:

1. Secondary multiplex retryable startup failures now enter the profile-scoped reconnect registry after _running=True (no live-but-deaf exit-78 suppression without a retry path).
2. is_global_startup_conflict recognizes production Telegram 409 getUpdates conflicts even under generic telegram_connect_error.
3. Buzz/IRC/LINE unpack acquire_scoped_lock()'s (acquired, existing) tuple so lock-conflict branches are reachable.

Verification (isolated HERMES_HOME): 166 passed, 2 skipped across focused gateway startup/status/adapter suites; Ruff + compileall + git diff --check clean on touched paths.

No merge/deploy requested — awaiting independent exact-head review.

The prior three HIGH findings are repaired in their direct paths, but two additional HIGH lifecycle/ownership defects were reproduced:

1. Secondary retry ownership bypass (gateway/run.py:11359-11365, 13738-13790, 13855-13878): a transiently failed secondary profile does not reserve its credential/listener claim. Another profile can consume the same token, then the first reconnects without rechecking shared ownership; same-process machine locks permit both. Reproduced two active Telegram profiles on one credential.
2. Initial secondary connect can escape shutdown (gateway/run.py:13781-13786, teardown 13359-13367): if stop() completes while secondary connect() is blocked, the late-success adapter is published into a detached local map and is never disconnected. Reproduced runner_registry={}, orphan_running=True, disconnect_called=False.

Required regressions:

• A transiently fails, B has the same token, A retries: exactly one profile may consume it; reconnect must share the startup credential/listener ownership registry.
• Block secondary initial connect, complete shutdown, release connect: exact adapter is disconnected and absent from runner registries.

Independent evidence: 144 focused tests passed, Ruff passed, diff-check passed; two adversarial probes reproduce the blockers. Do not merge/deploy this head. No repository files were modified by review.

HIGH-2 ownership/shutdown repair at exact head

(previous: 8983942625ebf6dbaf3ab28c9109c977d4a13944)

Repairs the two independent-review HIGH findings only:

1. Secondary retry ownership — transient secondary startup failures now reserve credential/listener claims in the shared ownership registry (_profile_retry_resource_claims + startup claimed map). Reconnect consults that registry before any external connect/publication, so a peer profile presenting the same Telegram token cannot create a duplicate poller. Same-process machine locks alone are not relied on.
2. Initial secondary startup/shutdown race — after awaiting secondary initial connect, publication is fenced on startup/shutdown state (_startup_should_abort). If stop()/registry teardown already completed, the exact late-success adapter is disconnected and never registered.

Prior HIGH-3 repairs preserved: telegram_connect_error 409 classification, Buzz/IRC/LINE lock tuple unpack, and normal secondary retry scheduling.

[yuzilongleif-collab]

I found one additional reconnect ownership race on exact head 13fb83231deccb0795eaa81562bd73d315c2007a.

_run_secondary_profile_reconnect() enters _profile_runtime_scope(profile_home) before calling _secondary_reconnect_claim_conflict(). _collect_adapter_resource_ownership() then labels self.adapters (the primary adapter registry) with the dynamically active profile from get_active_profile_name().

During an alpha retry, that makes primary/default claims look owned by alpha, so a newly reloaded secondary adapter can reuse the primary token/listener without being rejected.

Minimal probe:

runner = GatewayRunner.__new__(GatewayRunner)
runner.adapters = {Platform.TELEGRAM: TokenAdapter("shared-token")}
runner._failed_platforms = {}
runner._profile_adapters = {}
runner._profile_retry_resource_claims = {}
monkeypatch.setattr(
    "hermes_cli.profiles.get_active_profile_name", lambda: "alpha"
)

owner = runner._secondary_reconnect_claim_conflict(
    "alpha", Platform.TELEGRAM, TokenAdapter("shared-token")
)
assert owner == "default"

Actual: owner is None; the reconnect is allowed and its new claim is recorded for alpha.

The primary registry owner needs to be fixed/captured independently of the current secondary profile scope (for example, an explicit runner primary owner established at startup). A regression should cover: primary holds P, alpha is retrying after A, alpha's config changes to P, and the reconnect is refused before any external connect() call. The same owner relabeling applies to listener claims.

Maintainer review at exact head 13fb83231deccb0795eaa81562bd73d315c2007a — CHANGES REQUIRED, not merging at this head.

The direction is right and wanted: pure single-writer token-lock conflicts at zero-connected startup should exit 78 instead of retry-queueing forever, platform-local auth/config failures (Buzz membership, missing credentials) should park fatal per-platform while the lifecycle stays running for cron/Kanban/healthy peers, and avoiding a non-drainable degraded lifecycle state is the correct call (derive_gateway_busy/derive_gateway_drainable only understand running). The HIGH-3 and HIGH-2 repair rounds addressed their findings on their direct paths.

What blocks the merge:

1. @yuzilongleif-collab's reconnect ownership race is unaddressed at this head. _run_secondary_profile_reconnect() enters _profile_runtime_scope(profile_home) before _secondary_reconnect_claim_conflict(), so _collect_adapter_resource_ownership() labels the primary adapter registry with the dynamically active profile name — during an alpha retry, primary/default claims look owned by alpha and a reloaded secondary adapter can reuse the primary token/listener without rejection (their minimal probe shows owner is None where "default" is expected). This is the same defect class the HIGH-2 round fixed for the startup path, still open on the reconnect path. Please collect primary-registry ownership outside (or before) the profile scope, or pass the owning profile explicitly, and add their probe as a regression.

2. Review surface. This is now 690 production lines across gateway/run.py, gateway/restart.py and three adapters, grown through three repair rounds. After fixing (1), please also confirm the focused suites listed in the PR body still pass at the new exact head and post the run — the repair-round history makes it easy for a stale claim to linger.

No split demanded — the classifier + lifecycle + lock-tuple changes are one coherent contract and splitting them would leave intermediate heads in the live-but-deaf state the PR exists to eliminate. But (1) is a real duplicate-poller vector and can't ship.

Once (1) is repaired with a regression and the suites re-run at the new head, ping and we'll re-review promptly — the underlying fix is wanted.

fix(gateway): classify real token locks and keep lifecycle running

Well-scoped fix with strong regression coverage (real _acquire_platform_lock path, Telegram 409 envelope, secondary multiplex). Observations:

1. gateway/restart.py — is_global_startup_conflict() treats any error code ending in _lock as a global single-writer conflict (code.endswith("_lock")). That matches the production {scope}_lock families emitted by _acquire_platform_lock, but it will also catch any future unrelated code like db_lock or socket_lock and force exit-78 on a platform-local error. Consider matching against the known lock scopes, or requiring the message to also carry "already in use"-style semantics, to keep the bucket tight.

2. gateway/run.py — after start(), a failure to schedule a secondary reconnect is logged at DEBUG (logger.debug("Failed to schedule secondary %s reconnect ...")). If scheduling fails for every retryable secondary, the profile is left "live but deaf" with nothing visible in the logs — the same failure mode this PR fixes at startup. A WARNING (at least on repeated failure) would make that observable.

3. The Buzz/IRC/LINE acquire_scoped_lock tuple-unpack fixes are correct, but the platform-adapter authoring docs (website/docs/developer-guide/adding-platform-adapters.md, if not acquire_scoped_lock("newplat", self._token):) still show the old truthiness bug — a new adapter copy-pasted from the docs will reintroduce it. Update the doc example to unpack (acquired, existing).

4. _record_startup_adapter_failure() — a retryable fatal error with queue_retry=True but no platform_config (or a bare-exception path with no adapter) is appended to startup_retryable_errors but never queued, and returns False. That suppresses exit-78 while nothing will ever retry. If that combination is reachable from the primary path, log it loudly or refuse to suppress exit-78.
