fix(telegram): harden durable topic authority on current dev

[twoimo]

Summary

Replacement for the closed Telegram topic-authority review, rebased onto current upstream/dev (3bddcc579).

• Hardens durable topic authority and archive recovery.
• Treats archive settlement as idempotent only for Telegram HTTP 400 responses with documented not-found/already-closed descriptions.
• Keeps non-400 responses retryable.
• Updates the generation manifest and focused adversarial coverage.

Verification

• Darwin arm64 native addon build: passed
• Focused Telegram suites: 611 passed, 0 failed
• Telegram generation guard tests: 48 passed, 0 failed
• Coding-agent typecheck: passed
• Biome checks on changed Telegram/generated files: passed
• Current-tree generation guard validation: passed
• git diff --check: passed

The prior PR #3700 is closed; this branch is published separately for fresh maintainer review. No merge is requested by this session.

[twoimo]

Addressed the exact-head generation-guard failure: current dev declares DAEMON_GENERATION = 56, so this branch now advances the authority generation to 57 and updates the manifest/assertions. Focused Telegram tests remain 611/611; generation guard tests 48/48; typecheck, Biome, and current-tree validation pass. Pushed as ada2c7cbf; waiting for fresh CI and review.

[twoimo]

Resolved the fresh public-surface failure: current dev requires the generated docs index to remain ignored/untracked. Removed packages/coding-agent/src/internal-urls/docs-index.generated.ts from the branch index while retaining generator validation; pushed bba9042a7. No product Telegram code changed in this correction. Waiting for fresh CI.

[twoimo]

All exact-head checks are now green on bba9042a7 (affected-path validation, native build, Windows Telegram safety, generation guard, state gates, and local public surfaces). The branch is mergeable and the generated-doc policy is clean. Please re-review PR #4042 when convenient; this session will not merge it.

REQUEST_CHANGES

Reviewed the actual current PR head bba9042a78ef3112947358c1400ea5b2dc5036e5 (not the unrelated requested 31c00c2d5, which is PR #4051). The patch removes the authority-fenced markDaemonOwnerStopped persistence path and the bounded compensation-fence retry handling, while also removing the owner-postmortem/outage-resilience coverage from the manifest. During a shared-authority outage, a dead owner can remain durable-ready and archive/ownership settlement can lose its bounded recovery guarantee. Restore the fenced durable settlement behavior and focused failure-path coverage before approval.

The strict Telegram HTTP 400 archive allowlist is correctly narrower, but it does not offset the removed durability safeguards. Current CI failures on 31c00c2d5 are current-dev failures (GC disk retention and SDK host wiring/default-model timeout), not attributed to this PR.

REQUEST_CHANGES — exact-head review of bba9042a78ef3112947358c1400ea5b2dc5036e5 against refreshed origin/dev 427cef2a82fe15d790b63c9f0872f32c8b632d2d (merge-base 3bddcc579717eb47eedafc9db29a86aa86c4438a).

This external CONTRIBUTOR branch removes established fail-closed durability behavior and its mutation-sensitive coverage:

1. runDaemonInternal no longer registers the postmortem callback or calls markDaemonOwnerStopped in finally, while the durable-ready state still relies on stoppedAt to invalidate a dead owner. A fatal exit or failed final persistence can again leave a non-existent process advertised as ready. Restore the identity-fenced stopped marker on both abnormal and normal teardown paths, and keep the lifecycle-wiring test in the baseline.

2. The fire-and-forget liveness renewal, scan timer, and flush timer again discard rejecting promises. A transient shared-authority failure can escape as an unhandled rejection and terminate the owner. Restore the rejection boundaries that log sanitized diagnostics and permit a later tick/scan to retry; preserve the focused outage tests.

3. The compensation fence changes from bounded, supervised recovery to an unbounded tracked retry loop. During a persistent authority outage it keeps a shutdown effect non-quiescent forever. Reinstate a bounded recovery policy (with observable failure reporting and a later retry path) and its test.

The stricter HTTP 400 archive allowlist is correct, and the generated generation manifest is synchronized. All displayed CI checks are green, but they do not cover the removed durability contracts; the exact-head isolated test attempt was blocked locally by the environment’s node-pty install hook (node-gyp cannot resolve nopt). No automated/Codex review threads or inline comments are present. Not LGTM.

Closing this older overlapping Telegram authority branch in favor of its explicit successor #4043, which will be the single active repair owner for the retained archive-settlement intent and the current durability/concurrency blockers. Keeping both branches active would duplicate mutation ownership over the same Telegram authority surface.
