Change

Interim released-behavior clarification for shared #215, alongside Website #307. Website #302 has been superseded by the actual advancing replay-safe clock requirement.

Document Python 2.6.1's current fixed run-start ctx.now(), successor-run anchors, persisted timestamp precedence, missing-clock diagnostics, durable timers/Server deadlines and sequence-based event ordering. Preserve the currently released #146 behavior in this docs-only PR; #215 owns the new advancing clock and replay-compatible migration.

Only docs/sdk-reference.md changes. No runtime, dependency, protocol or version change, and no claim of normalized cross-SDK clocks.

Verification

• Normal PyPI Python 2.6.1; loaded workflow SHA-256 a28a4b585269ccca2643cf0a8dd82ae6a4800625a53ffa1940c5e85df12865aa matches the immutable release.
• The example and seven constructed-history controls pass in each of two independent replay processes, including timer scheduling, fixed clock after timer completion, replay/input immutability, successor anchor and invalid/missing clock diagnostics.
• Example matches Website #307. No live Server timing comparison is claimed.

General retains merge and portal-publication acceptance. Publishing this clarification does not complete shared #215.

Published portal acceptance is now verified for this interim documentation correction.

• Merged source 412a10f / tree 71f8ab19800e34eb003d03f1989bda77fe5cd98d; only docs/sdk-reference.md changed. The remote head docs/fixed-workflow-start-clock is retired (exact ref returns 404).
• Normal portal run 39399839289 passed build and deployment; deployment completed 2026-10-20 10:13:42 UTC.
• Live deployment audit identifies that exact merged source and SDK 2.6.1. The live SDK reference contains WaitWithoutClockLoop, the persisted start-time contract and the separate monotonic-clock guidance.
• Final verification 2026-10-20 10:41:22 UTC: all 15 exact-main check runs PASS, including CI 39399839051, all Python versions, integration, regression corpus, package, lint, advisory throughput, target-branch qualification, Sonar and boundary. The live audit still matches that exact merged source.

This documents the currently released fixed-start behavior. It does not deliver an advancing replay clock: .github #215 remains OPEN, and Website #302 remains superseded by that product feature.

No new runtime or qualification phase was needed; all task runtime/dependency/raw state remains retired.
