## Summary
- Adds the user-facing stable release changelog at
`releases/v2026.511.0.md`, generated per
[`.agents/skills/release-changelog/SKILL.md`](../blob/master/.agents/skills/release-changelog/SKILL.md)
from the 89 commits between `v2026.428.0` and `origin/master`.
- Surfaces nine headline themes: planning mode, full company search,
routine revision history, recovery system notices, expanded plugin host,
**secrets provider vaults + remote import**, **Cursor cloud adapter**,
**Daytona sandbox provider plugin**, and the ACPX local adapter — plus
categorized improvements/fixes.
- Documents nine new additive/idempotent migrations (`0075`–`0083`) in
the Upgrade Guide, including the `fuzzystrmatch` extension requirement
for company search and the `provider_config_id` text→uuid retype on
`company_secrets`.
Branch retains its `release/v2026.506.0` name to avoid PR churn; only
the artifact filename and content track the actual release date. Branch
was rebased onto current `origin/master` and force-pushed with a single
squashed commit.
No `BREAKING:` / `BREAKING CHANGE:` / `feat!:` signals across the full
range.
## Test plan
- [ ] Maintainer review of the draft changelog content for tone/scope
- [ ] Confirm the headline grouping reflects intended release messaging
- [ ] Confirm the migration list and upgrade guide match runtime
behavior
- [ ] Confirm the `0083` `provider_config_id` retype guidance is
acceptable for the release notes
