Conversation
The Python port of YaFT, first stage: evaluation (R3-R13, R27, R28), response mapping (R22-R25, R29, R30), local providers in both shapes and the feature_toggle decorator for functions, methods and classes (R14-R19). The adapter runs every case of yaft-conformance 4.0.0, pinned in conformance.lock; mutation-checked against eight injected bugs. Beyond the suite: async def stays a coroutine function, generators turn into an empty iterator when off, static and class methods can be toggled, and an off class without a fallback becomes an empty shell that accepts any constructor arguments. Timestamps are computed to epoch milliseconds by hand, so the range and truncation match JavaScript. No runtime dependencies; Python 3.11 and later, tested on 3.11 and 3.14 in CI. The API provider and PyPI publishing come next. Claude-Session: https://claude.ai/code/session_01SDYfZZQsaZpLvSwDgHYcr7

parse_timestamp computed epoch milliseconds with its own calendar code, only to accept the same years as Date.parse. datetime already rejects an impossible date, time and leap second (R11, R12) and takes offsets below 24 hours (R28); only offset minutes above 59 need checking by hand. It now returns an aware datetime. The one difference, year 0000, is not a timestamp anyone sends. A key or value that is not a string was written out like JavaScript's String() to match the other ports. JSON booleans belong in the boolean shape: in the feature shape a non-string is now not set, so the value is off and a keyless entry is skipped (R1, R4, R25).

Pin the privileged reusable workflow to a reviewed commit.
This job loads tehw0lf/workflows from the mutable main branch and grants the called workflow the write permissions on Lines 12–19. A later change to that branch can run with those permissions without a change to this repository. Pin the reusable workflow to a full commit SHA, and limit the caller’s permissions to those its jobs require. (docs.github.com)

Declined, by a standing decision for all YaFT ports: tehw0lf/workflows are the owner's own reusable workflows, protected by a ruleset on main, and callers stay on @main on purpose. Build and publish rights are already separated: every sub-job of the orchestrator gets only the permissions and secrets it needs, and this caller passes no secrets at all (OIDC only).

@tehw0lf, thanks for the guidance. I understand that YaFT ports use tehw0lf/workflows@main by design and that a ruleset protects main. I will not press for a commit pin here. I have not independently verified the sub-job permissions.

Learning: For YaFT ports, the owner intentionally references `tehw0lf/workflows` reusable workflows at `main` rather than pinning a commit SHA. The owner states that a ruleset protects `main`, the orchestrator separates build and publish permissions by sub-job, and callers pass no secrets while using OIDC.
Note: Learnings are effective only in the context of similar code segments. To apply general coding guidelines, please configure review instructions. You can manage existing learnings in the app.
