docs: converge #691 vulnerability-reporting reader authority

[seonghobae]

Documentation authority gap

Protected #691 source is merged at GitHub-verified main@b199ad1f0bed0ecd545e46e327e0bed6fff9224e, but canonical CHANGELOG/product-gap authority did not record the private-vulnerability-reporting locked/non-stream-readable response reader-acquisition repair.

Test-first RED

Test-only exact 4a779f4551acc8db250fe3d6d9b5d16f79d10f46 requires canonical documentation to retain #691 source exact 65e0d3dd3c4060ba0057ba13cf6c9ea23b03373d, protected merge b199ad1f..., the stable GitHub private vulnerability reporting response body could not be read. diagnostic, existing 16 KiB/media/fatal UTF-8/duplicate-key/JSON bounds, immutable-release separation, and existing GitHub setting/security/outbound/credential ownership boundaries.

Hosted application CI 34714708242 passed exact checkout, package-manager/live-base/lockfile controls, install and release typecheck, then failed at release tests as intended because the protected documentation lacked those #691 authority strings. Reviewer-ci 34714708181 and required Security Scan 34714708354 independently succeeded on the same RED exact; no predecessor GREEN is transferred.

Minimal documentation repair

Current exact b5470e5b50e7b6f8ae74ffe288771e156426f963 changes documentation authority only: it adds the #691 protected source/merge/fail-closed/ownership boundary to CHANGELOG and the product-technical gap baseline while retaining the executable documentation regression. Runtime source is unchanged. An unrelated historical #650 CHANGELOG wording drift introduced by the earlier documentation edit was detected and restored.

CodeRabbit identified one valid review finding on predecessor exact 9753ec737eb1524cdb08f8583ed872d72045d250: the test checked #691's protected merge but did not independently pin the earlier dated #689 protected observation. The current test now verifies main@620b29fa... and #691 merge b199ad1f... as separate exact statements; the thread is resolved only after that minimal repair.

Exact-head required workflows must all reach terminal success, and current-head review/thread state must be clean, before this PR is merge-authoritative. Protected source/CI evidence is not an immutable release, deployment, live vulnerability-reporting enablement or notification staffing, recovery rehearsal, or deployed p95/heap evidence.

Exact-head maintainer review on b5470e5b50e7b6f8ae74ffe288771e156426f963: reviewed the three-file documentation-authority diff after CodeRabbit's valid protected-observation finding was repaired. Runtime source is unchanged; the historical #650 CHANGELOG drift is restored; #689 dated observation and #691 merge identities are pinned separately. Application CI 34716563236, reviewer-ci 34716563263, required Security Scan 34716563281, and patch-validator-image 34716563238 are terminal SUCCESS on this exact head. No unresolved inline review thread remains. COMMENT only; this is not self-approval.
