From 37e99329eeb9df77b0024c8795ff55de0a5b2ce0 Mon Sep 17 00:00:00 2001 From: fylorn <249551762+fylorn@users.noreply.github.com> Date: Fri, 2 Oct 2026 22:01:40 +0800 Subject: [PATCH] Default plugins core ships, and route-first request hook tests The examples become the default plugins of contract addendum 1, in crates/tw-gateway/src/plugin/defaults/ (the registry and seeding, defaults/mod.rs, are another track's): - reply-language: one fixed instruction to answer in a language; the setting takes only a language name, so it cannot carry an instruction. - current-date: today's date for a UTC offset, default UTC+8. - term-unify: wrong=right pairs, one per line, in stream mode. Text that may start a term is held until the next piece, including when a shorter term already matches, so the longest term wins. - reply-redact: regexes one per line and a replacement, in block mode; off until patterns are set. - wsl-paths: drive paths in tool-call arguments, in answers and in earlier calls in the history, between /mnt/c/... and C:\...; a single boolean setting, and command lines, text and tool results are left alone. - deepseek-flags: replaces U+1F1F9 U+1F1FC, which DeepSeek's API refuses, with an ASCII placeholder in the system prompt, messages, tool results and earlier tool calls, and restores it in answer text and tool calls; no settings, default scope deepseek*. "Strip parameters an upstream rejects" is dropped. Every default is loaded through the production sandbox and run in all four client formats, including CRLF multi-line settings, a poisoned DeepSeek history and a byte-identical request when the pair is absent. The I8 tests move to addendum 2 (route first, then the request hook per upstream attempt). Tests for failover starting again from the client's original, upstream scope for request hooks, broken plugins refusing only their attempts, failures not failing over, a plugin's params.model renaming without re-routing, and ctx.upstream / model / requested_model are written and ignored as pending until the rework lands. The same-upstream resend test stays active. The key's model list check on a plugin-chosen model is ignored with the reason, since addendum 2 no longer re-checks it.
