v7.6.3

# AVA Core v7.6.3

Released from reviewed main commit `56f20097d013e33783a07d414a6bf7dff936a7ce`.

## Highlights

- More reliable provider validation, including configured endpoints, credentials, and stale UI results.
- Opt-in Google Developer long-response playback and cloud-provider startup recovery, with existing defaults preserved.
- Local AI connection-test improvements, Whisper idle finalization, DTMF log privacy, and safer Google transfer handoff ownership.
- Streamable HTTP MCP backend support with Agent filtering, credential-safe diagnostics, and no automatic replay after a timed-out tool call. Admin UI editing remains follow-up #703.
- Compatible dependency/security maintenance, a shorter Core-first README, refreshed upgrade guidance and contributor credits, and a fork-safe opt-in Codex review workflow.

See the [full changelog](https://github.com/hkjarral/AVA-AI-Voice-Agent-for-Asterisk/blob/v7.6.3/CHANGELOG.md) for scope, limitations, and linked changes. Unmerged contributor and Dependabot PRs are not included.

## Upgrade

Follow the [installation and recovery guide](https://github.com/hkjarral/AVA-AI-Voice-Agent-for-Asterisk/blob/v7.6.3/docs/INSTALLATION.md#upgrade-to-v763-existing-checkout) and [v7.6.2 to v7.6.3 migration notes](https://github.com/hkjarral/AVA-AI-Voice-Agent-for-Asterisk/blob/v7.6.3/docs/MIGRATION.md#v762-to-v763).

Rebuild or update the AI Engine and Admin UI; rebuild Local AI only where it is used. Preserve configuration, Agent data, credentials, calendar identities, models, and local overlays. No database migration or provider/transport/model-default change is introduced. New playback/recovery options remain opt-in.

## Downloads

Release assets include Agent CLI binaries for Linux amd64/arm64, macOS amd64/arm64, Windows amd64, `SHA256SUMS`, and the CLI tarball. Verify downloaded binaries against `SHA256SUMS` before installation; run `agent version` after installing the matching platform binary.

The release image workflow publishes `v7.6.3` and `latest` tags for `ai-engine`, `local-ai-server` (core profile, models not bundled), `admin-ui`, and `updater` under `ghcr.io/hkjarral/asterisk-ai-voice-agent-*`.

## Validation and acceptance

- Exact-main [CI](https://github.com/hkjarral/AVA-AI-Voice-Agent-for-Asterisk/actions/runs/38202594336), [CodeQL](https://github.com/hkjarral/AVA-AI-Voice-Agent-for-Asterisk/actions/runs/38202594389), and [extended regression checks](https://github.com/hkjarral/AVA-AI-Voice-Agent-for-Asterisk/actions/runs/38202594436) passed.
- The [real-fork label smoke test](https://github.com/hkjarral/AVA-AI-Voice-Agent-for-Asterisk/actions/runs/38203461659) passed request resolution, review, and exact-commit publication. Its disposable PR was closed without merging.
- The maintainer confirmed runtime and upgrade testing was complete and explicitly waived additional testing. This acceptance is [recorded on the release PR](https://github.com/hkjarral/AVA-AI-Voice-Agent-for-Asterisk/pull/733#issuecomment-6117707360); it is not a claim of new agent-executed calls or deployment.
- The [preparation validation matrix](https://github.com/hkjarral/AVA-AI-Voice-Agent-for-Asterisk/blob/v7.6.3/docs/baselines/golden/v7.6.3-validation-matrix.md) preserves feature-specific evidence and limits; the release PR records completion of its post-merge gates.

## Published artifact verification

- [Release CLI Binaries](https://github.com/hkjarral/AVA-AI-Voice-Agent-for-Asterisk/actions/runs/38205574889) and [Release Images (GHCR)](https://github.com/hkjarral/AVA-AI-Voice-Agent-for-Asterisk/actions/runs/38205574947) both passed on the tagged commit.
- All seven downloaded assets match GitHub's SHA-256 digests; all five binaries match `SHA256SUMS`; every CLI tarball member matches its standalone asset.
- All five binaries embed version `v7.6.3`, source revision `56f20097d013e33783a07d414a6bf7dff936a7ce`, and an unmodified source tree. The downloaded macOS arm64 binary's `version` command passed; the release workflow also exercised Linux amd64.
- All four GHCR images have matching `v7.6.3`/`latest` manifest digests and build provenance for that same source revision. Updater provenance pins `AAVA_CLI_VERSION=7.6.3`.
