What does this PR change?

There was no release: no version bump, no changelog from merged pull requests, and nothing to download. This adds release-please, as in photoshop-plugin: merging the release pull request builds scenario-maya-X.Y.Z.zip from the release commit (tools/package.py: the module, its vendored SDK, install_scenario.py, the licence; reproducible), checks it byte for byte against that commit (tools/release/check_package.py), attests it, attaches it with SHA256SUMS and a Sigstore bundle to a draft, checks it again on macOS, and publishes the draft. publish-changelog.yml then posts the notes to www.scenario.com/changelog. The draft finder and the contributors section are ported from photoshop-plugin's JavaScript to Python. The first release is 0.1.0 (the manifest starts at 0.0.0).

After merge, an administrator sets what RELEASING.md lists: the release App on this repository, a tag ruleset on maya-plugin-v*, and maya-plugin as a source of the changelog ingest (plus CHANGELOG_INGEST_SECRET).

Validation

• uv run --with pytest pytest -q passes; for changes that touch Maya code, tools/test_maya.sh passes too. The Maya version and OS are listed below.
• python3 tools/lint.py, uvx ruff check . and uvx ruff format --check . pass.
• Packaging changes: the release ZIP installs by dragging install_scenario.py onto a Maya viewport with no errors or warnings in the Script Editor, and its contents were inspected.
• Maya or UI changes were tried in a Maya session (tools/test_maya_gui.sh or by hand), with before/after screenshots for UI.
• Live status is stated: python3 tools/contract_check.py (free) when calls to Scenario change; any paid run had prior authorization for its project and budget.

Commands and results:

• uv run --python 3.13 --with pytest pytest -q: 180 passed, including tests/unit/test_release.py (draft finder and contributors with fake GitHub answers, the ZIP's contents and dates, the check finding a changed file, a wrong version and a name twice).
• tools/package.py twice: the same SHA-256 both times; 19.3 MB; tools/release/check_package.py OK.
• The ZIP unzipped and installed with its own install_scenario.py in headless mayapy 2027.2 (macOS arm64): the plug-in loads from the Maya modules folder, and the SDK and the pydantic_core build for this Maya load from the installed copy. In the Maya 2027.2 GUI, the ZIP's install_scenario.py installed through Maya's drop handler in 0.8 s: plug-in loaded from the modules folder, autoload on, panel docked, Scenario menu; then the end-to-end run of feat(core): call Scenario's REST API through its Python SDK #16 (sign-in, a real generation, restart, sign-out) ran on that install.
• A Maya .mod file with # x-release-please-start-version comment lines loads in Maya 2027.2 with its version read.
• Not run on GitHub: the release workflow itself (it needs the release App and a merged release pull request).

Public content

• No credentials, tokens, signed URL query strings, or private account, team, project, job or asset IDs are included.
• No personal paths, machine details, agent session IDs or spend anecdotes are included.

Rules

• The spending rules in AGENTS.md still hold (price check first, single-use quotes, paid calls sent once, SCENARIO_NO_SPEND).
• No unrelated manual version or changelog edits; documentation matches the resulting behavior.

Authorship and licensing

• Human review of the complete diff is recorded before merge.
• Adopted third-party code or assets keep their compatible licenses and attribution; original contributions are licensed under MIT, the repository license.

Written with Claude Code (Claude Opus 5.5). The release tools are ported from photoshop-plugin (MIT, same organization).

Merge Risk: Minimal · up to a208b

The release packaging check now rejects ZIPs that contain the same file name twice, so a tampered earlier entry can no longer pass unnoticed. No concrete merge-blocking issue remains in the reviewed changes. The release workflow itself still needs the administrator setup described in the PR before its first real run.

Security architecture risk: Low · up to a208b

The release pipeline has strong commit-binding and validation gates. The main bounded concern is that opting into retained GUI-test sign-in leaves credentials beyond the test sequence without automatic final cleanup. Release permissions and repository protection settings also require administrator configuration.

Retained concerns

• Low · security · observed: With SCENARIO_GUI_KEEP_SIGNED_IN=1, the OAuth test skips sign-out, but neither the following generate stage nor runner shutdown assumes responsibility for final cleanup. On the default macOS store, the refresh token remains in the shared login Keychain rather than the throwaway preferences directory. This extends credential availability beyond the opted-in test sequence, including its failure paths. Exposure is limited by explicit opt-in and local credential-store access; requesting a later restart stage provides a sign-out path.

Security review details

Security Blast Radius

• inferred — The consequential release outcomes are publication of executable plug-in downloads and submission of notes to the public changelog. The OAuth concern affects the consenting local user's retained credentials under their existing grants, not a demonstrated remote or cross-tenant privilege escalation. Actual App-installation and ingest-secret authority are not established by repository source.

Security Findings and Attack Paths

• inferred — Opted-in retention increases the period during which a process able to read the user's credential store could obtain the OAuth refresh token. The new behavior is skipped cleanup, not a newly introduced storage vulnerability. No remote acquisition path or additional token permissions were demonstrated.

Trust Boundaries and Controls

• observed — Release execution is restricted to the target repository on main pushes. Checkout credentials are not persisted; recovered drafts require the expected App author and exact commit. Changelog inputs enter through environment variables and JSON encoding, and only published stable releases proceed. The ingest bearer credential is sent through curl configuration on stdin rather than as a command-line header argument.
• observed — The final publish step checks draft state, commit and required filenames, but does not re-download and verify the attached bytes or consume the validated release ID. This leaves privileged draft mutation within the trusted boundary; the inspected evidence does not establish an unprivileged bypass.

Resilience and Maintainability Implications

• observed — The changelog client distinguishes queue acceptance from publication and warns when a version already exists. Rerunning does not request an overwrite or repair a failed existing entry; documented recovery requires checking the external entry's processing state.

Hardening Proposals

• proposed — Give the opted-in test sequence an explicit final cleanup owner, with revocation on normal completion and recoverable cleanup after interruption. Keep inter-stage persistence distinct from intentionally retaining credentials after the entire run.
• proposed — Before enabling production publication, verify the App's effective grants, tag-rule bypass principals, immutable-release setting and ingest-secret scope. If privileged draft writers are outside the intended trust boundary, bind publication to the validated release ID and verify the attached bytes and provenance immediately before publication.

Full details: Title check

Explanation

The title follows the repository's type(scope): summary convention with the ci(release) scope and describes the main change: a release workflow that builds and checks a ZIP and uses release-please. It is specific and under 120 characters. It leaves out the changelog publishing, which the objectives also mention, but that is a secondary part of the change.

Full details: Description check

Explanation

The description covers the main sections of the template: what changes, the validation checklist with results, public content, rules, and authorship. It explains the release flow, the packaging and check tools, the first release version, and the administrator steps needed after merge. Some template items are unticked, which the template allows. The Maya GUI validation item and the human-review item are unticked, and the template says to leave unchecked items unticked. The description has no 'Closes' or 'Refs' issue reference, and the template asks for one. The description also does not state whether a Maya GUI check was run, although the commands list reports GUI results. The description also gives no before/after or screenshots, which the template does not require for this non-UI change.
