Five fixes for latent regressions surfaced during the v1.13.x.cosmetic
revert investigation. None alter schema or compaction; all cleanup
against the v1.13.1-A AI SDK migration's hidden surface.
(1) provider.ts — includeUsage: true on createOpenAICompatible.
@ai-sdk/openai-compatible defaults this false, omitting
stream_options.include_usage from the request body; llama-swap never
emitted the usage block, so result.usage.inputTokens/outputTokens
resolved undefined and tokens_used / ctx_used landed NULL in every
assistant row since v1.13.1-A. No historical backfill.
(2) MessageList.tsx — hasText = m.content.trim().length > 0.
AI SDK v6 streaming occasionally emits a leading "\n" text-delta on
tool-call-only turns; the literal newline passed length > 0 and
rendered an empty bubble + ActionRow between every tool call. Trim
catches it without changing semantics for genuine content.
(3) MessageBubble.tsx — same trim on hasContent for the no-tool-calls
path. Defensive symmetry with MessageList.flatten.
(4) payload.ts — buildMessagesPayload skips assistant rows with
status='failed' AND assistant rows with status='complete' + empty
content + no tool_calls. Without this, a trailing empty/failed
assistant + the next attempt's placeholder produced "Cannot have 2
or more assistant messages at the end of the list" rejections from
the OpenAI-compatible upstream after cap-hit + Continue.
(5) budget.ts — BUDGET_NO_AGENT 15 → 30. Every tool in ALL_TOOLS is
read-only today; the 15-cap was forward-looking for write tools that
haven't landed. No-agent mode now matches BUDGET_READ_ONLY.
47 LoC across 5 files. 190/190 server tests pass.
Verified live: new assistant turns populate StatsLine token data;
single-tool-call turns no longer render the stray empty-bubble +
ActionRow between tool calls; Continue after cap-hit no longer hits
the trailing-assistant API rejection.
Pure file moves. No behavior change. inference.ts retains createInferenceRunner
public surface; new files are internal to services/inference/.
- budget.ts: resolveToolBudget
- sentinels.ts: detectDoomLoop (re-exported through inference.ts),
isCapHitSentinel, isDoomLoopSentinel, isAnySentinel
- xml-parser.ts: parseXmlToolCall, partialXmlOpenerStart
First of four refactor batches preparing inference.ts for the v1.13
AI SDK migration. inference.ts goes from 1780 LoC to ~1620.
