feat(harness): remove HARNESS_SESSION_HISTORY_ENABLED flag (#1098)#1099
Conversation
Executes the #1062 DP v3 rollout plan: history threading (#1071) and cold hydration (#1085) are now unconditional. The HARNESS_ALLOW_ANON_HYDRATION interlock is retained as a separate Zapp-M4 defense against the #1079 anon-sessionId guess vector. Adopts Nibbler nit: default-behavior test in history-threading.test.ts now asserts threading without any env-var setup.

Code Quality
VerdictThis change safely transitions history threading and cold hydration from feature-flagged (off-by-default) to unconditional behavior, while preserving all upstream security controls (anon interlock, guardrails, trust markers). Approved by Zapp (Security reviewer) ✓ |
Code Review — PR #1099 ✅Checkpoints:
Code quality: Unconditional adoption is sound. Comments updated to reflect new invariants (e.g., runner.ts line ~671 now says "unconditional since #1098 rollout"). No type errors; rollInput is now correctly Approved for merge. Closes #1098 per DP v3 rollout plan (#1062). ✅ |

…xistent 'kickstart' - Changed '@kickstart' to '@aks-kickstart/harness' and '@aks-kickstart/web' - The changeset references packages that actually exist in the workspace - This fixes the CI failure in 'Lint, Build & Unit Tests' where changesets were failing
The 1087-token-governance-hardening.md changeset references a nonexistent 'kickstart' package and was created in #1091. Since that PR has already been merged and released, this changeset file should have been consumed by the release process. Removing it resolves CI failures in the changeset validation step.
