Cut v0.77.0 — pi 0.76.0→0.77.0

First container build on pi 0.77 line (published upstream 2026-05-28).
Built against unchanged joakimp/opencode-devbox:base-latest (same as
v0.76.0 — SSH-CM, gitleaks, git-crypt all carry forward).

Notable pi 0.77.0 upstream:
- Claude Opus 4.8 support
- --exclude-tools / -xt for selective tool disablement
- Headless Codex subscription login (device-code auth)
- Streaming-aware extension input (InputEvent.streamingBehavior)
- Long bugfix list (startup timing, signal handling, terminal
  protocol detection, Windows MSYS2 fixes, provider metadata
  cleanups, session disposal abort, etc).

Also folds the previously-Unreleased CI retry-wrapper change
(2d39766) into this release block. Second publish exercising the
cache-export-disabled workflow; first to exercise the 3-attempt
retry wrapper through the publish path.

See CHANGELOG v0.77.0 for full notes.

+pi `0.76.0` → `0.77.0` bump (first container build on the pi 0.77 line, published upstream 2026-05-28). Built against `joakimp/opencode-devbox:base-latest` (unchanged from the v0.76.0 build — same SSH-CM, gitleaks, git-crypt baked in).
+
+### Bumped: pi 0.76.0 → 0.77.0
+
+Notable upstream changes (from pi's CHANGELOG):
+
+- **Claude Opus 4.8 support** — Anthropic Opus 4.8 model metadata + adaptive-thinking coverage updated.
+- **Selective tool disablement** — `--exclude-tools` / `-xt` disables specific built-in, extension, or custom tools while leaving the rest available.
+- **Headless Codex subscription login** — `/login` can use device-code auth for ChatGPT Plus/Pro Codex subscriptions; browser login remains the default.
+- **Streaming-aware extension input** — `InputEvent.streamingBehavior` lets extensions distinguish idle prompts from mid-stream steers and queued follow-ups.
+- **Bugfixes** — startup timing output excludes `createAgentSessionRuntime` work; OpenRouter DeepSeek V4 `xhigh` reasoning preserves OpenRouter's native effort; SIGTERM/SIGHUP exits run extension `session_shutdown` cleanup; keyboard protocol negotiation ignores delayed terminal responses (no false Kitty detection); Windows MSYS2 ucrt64 startup crash fixed via napi-rs 3.x clipboard addon; API-key/header config resolution treats plain strings as literals with `$ENV_VAR` / `${ENV_VAR}` interpolation and `$!` escaping; session disposal aborts in-flight agent/compaction/branch-summary/retry/bash work; `pi.getAllTools()` exposes per-tool `promptGuidelines`; OpenAI Codex Responses replay after switching from Anthropic extended-thinking sessions; Anthropic-compatible replay supports `allowEmptySignature` for providers returning empty thinking signatures; OpenAI/OpenRouter GPT-5.5 Pro thinking levels limited to supported efforts; OpenCode Go Kimi K2.6 thinking-off requests; Xiaomi Token Plan model metadata cleaned of unsupported variants; follow-up messages queued by `agent_end` extension handlers drain before idle; system prompt tool-selection guidance avoids unavailable file-exploration tools; fenced `diff` highlighting restored.
+
+Workflow continues to derive `PI_VERSION` from the git tag (`v0.77.0` → `0.77.0`) and pass it as a build-arg per the v0.75.5b cache-hit fix; smoke test asserts `pi --version` matches.
+
+### Inheritance from base
+
+No base change in `joakimp/opencode-devbox:base-latest` since v0.76.0 — the v1.15.12 opencode-devbox release also reused the unchanged base. SSH ControlMaster on a writable socket path, gitleaks, and git-crypt continue to ride along from the base.
+
+### CI
+
+This is the second pi-devbox release exercising the cache-export-disabled workflow (after v0.76.0's clean publish on run #340) and the first to also exercise the 3-attempt retry wrapper added in 2d39766 along the publish path.
+
+## v0.76.0 — 2026-05-28
+
+pi `0.75.5` → `0.76.0` bump (first minor-version release on pi 0.76 line, published upstream 2026-05-27 20:03 UTC). Built against a fresh `joakimp/opencode-devbox:base-latest` which now bakes in SSH ControlMaster on a writable socket path, plus gitleaks and git-crypt — see the inherited-from-base notes below for details on each.
+
+### Bumped: pi 0.75.5 → 0.76.0
+
+Notable upstream changes (from pi's CHANGELOG):
+
+- **Explicit session IDs for automation** — `--session-id <id>` lets scripts create or resume an exact project-local session.
+- **RPC bash output can stay out of model context** — RPC clients can pass `excludeFromContext` to `bash` for commands whose output should not be sent with the next prompt.
+- **More predictable provider retries and timeouts** — Codex WebSocket/SSE waits are bounded; `retry.provider.maxRetries` controls provider retries instead of hidden SDK defaults; SDK retries default to 0; quota/billing 429s are no longer retried behind Pi's retry handling.
+- **Better terminal editing across environments** — Apple Terminal Shift+Enter detection on macOS, Windows Terminal OSC 8 hyperlink support, JetBrains truecolor with disabled OSC 8, Unicode-aware word navigation and deletion.
+- **Bugfixes** — `pi update` bypasses npm/pnpm/Bun minimum-release-age gates; user-authored ordered-list markers preserved in transcripts; image attachment token estimates aligned with tool-result images; Codex Responses cache-affinity header fixed (`session-id` not `session_id`); OpenRouter/Poolside context-overflow detection; managed npm extension updates avoid peer-dependency conflicts; RpcClient handles unexpected child exits cleanly.
+
+Workflow continues to derive `PI_VERSION` from the git tag (`v0.76.0` → `0.76.0`) and pass it as a build-arg, per the v0.75.5b cache-hit fix; smoke test asserts `pi --version` matches.
+
+### Workflow change: registry cache-export disabled
+
+- **`.gitea/workflows/docker-publish.yml`** — `cache-from`/`cache-to` removed from the `publish` step. buildkit's `mode=max` cache-export to `registry-1.docker.io` reproducibly returns HTTP 400 on the resumable-upload PUT, surfacing ~2026-05-23. Diagnosed during opencode-devbox v1.15.12's manual host-side publish: image push works fine, only `--cache-to` fails. See opencode-devbox CHANGELOG v1.15.12 `Unreleased` for the full root-cause analysis. The pi-devbox Dockerfile is single-stage with a tiny diff (npm install pi only) on top of `base-latest`, so builds are fast even without cache (~30-60s expected).
+
+### Inherited from opencode-devbox base: SSH ControlMaster on a writable socket path
+
+No Dockerfile change here — just a note that this release picks up the system-wide SSH ControlMaster default (`/etc/ssh/ssh_config.d/00-devbox-controlmaster.conf` → `ControlPath /tmp/sshcm/%r@%h:%p`, `ControlMaster auto`, `ControlPersist 10m`). This unblocks `ssh` and `pi --ssh user@host` from inside the container when `~/.ssh` is bind-mounted read-only from the host (the standard pi-devbox compose layout) — previously, OpenSSH's default `ControlPath` under `~/.ssh/cm/` was unwritable, so multiplexing failed with `unix_listener: cannot bind ... Read-only file system` and ssh fell back to fresh TCP connections, which on residential CGNAT manifested as banner-exchange timeouts. The fix is purely additive (per-container `/tmp/sshcm` dir, mode 700, created by entrypoint) and user `~/.ssh/config` per-host overrides still win because Debian's stock `ssh_config` sources `ssh_config.d/*.conf` before its own `Host *` block. See opencode-devbox CHANGELOG `v1.15.12` for the base-side details.
+
+### Inherited from opencode-devbox base: gitleaks + git-crypt
+
+No Dockerfile change here — just a note that this release includes `gitleaks` (newly added to the base) and `git-crypt` (was always installed via apt; just wasn't called out). Both are useful inside the container for repos that use a gitleaks pre-commit hook or git-crypt-encrypted canonical config and don't want host-side dependencies. See opencode-devbox CHANGELOG `v1.15.12` for the base-side details.

 ## v0.75.5b — 2026-05-23
 
 Recovery release fixing a **silent cache-hit regression** discovered in the v0.75.5 image. All four releases v0.74.0 through v0.75.5 had been shipping the same image bytes because the Dockerfile's `npm install -g @earendil-works/pi-coding-agent` (bare, when `PI_VERSION=latest`) produces an identical layer-hash across builds. Combined with the registry buildcache, Docker reused the layer from whatever pi version was current when the cache was first populated.
