- Migrated 288 lines of scattered error classification logic from `utils/error-id.ts` into a cohesive `packages/ai/src/error/` module with 13 specialized submodules covering flags, classes, OAuth, providers, rate-limiting, and finalization.
- Replaced 100+ generic `Error` throws across 60+ provider and registry files with semantic `AIError.*` classes (e.g., `AIError.MissingApiKeyError`, `AIError.OAuthError`, `AIError.ProviderResponseError`), improving error diagnostics and retry logic.
- Consolidated error utility imports from `pi-utils` and scattered classification functions into a single `AIError` namespace, reducing coupling and simplifying error handling across all packages.
- Added `rewrite-changelog.ts` and `fix-changelogs.ts` utilities to automate the consolidation of release notes using LLM-assisted processing.
- Updated multiple internal changelog files by consolidating redundant entries and improving phrasing for readability.
- Implemented `previewLine` utility in `coding-agent` to prevent visual spillover in status rows by managing text truncation and whitespace.
- Updated `package.json` with new workflow scripts for managing package-level change histories and documentation indexes.
- Added an extractText override to pi-mnemopi remember paths so stored content and mined facts can use different text.
- Routed coding-agent mnemopi retention to store the full transcript while extracting only user-authored turns.
- Tightened deterministic Instruction extraction to require an explicit I/you subject.
Fixes#3372
- Moved tokenization, CJK detection, and query logic from `helpers.ts` to `util/regex.ts`.
- Consolidated duplicated CJK character check logic into a single utility function.
- Exported restructured utilities to maintain existing functionality for the beam module.
- Updated the test configuration to specify an explicit compaction strategy.
- Enabled context-full compaction to match expected behavior during tests.
`MnemopiSessionState.retainMessages` hands `embed()` the chronological
multi-turn transcript (oldest -> newest). A naive `slice(0, max)` cap landed
on the oldest turns and dropped the most recent content, so every retained
episode past the cap collapsed onto essentially the same prefix vector and
dense recall could not match topics introduced after the first 8192 chars.
`capInputs` now routes oversized inputs through `clipToWindow`, which keeps
roughly half the cap from the head and half from the tail with a small
`[...]` elision marker between them. Short inputs and array reference pass-
through are unchanged. Falls back to a tail-only clip when `max` is too small
to fit a useful split. Locked in by a new `embedding-input-cap.test.ts` case
that pins markers at both ends of a 50k transcript and asserts both survive
the clip.
Fixes#3126
Defaulted MNEMOPI_EMBEDDING_MAX_INPUT_CHARS to 8192 so the automatic guard matches bge-m3 and OpenAI text-embedding context limits by default. Larger local embedding servers such as Qwen3-Embedding with 32k ctx can still raise the cap, and 0 still disables truncation.
Fixes#3126
`MnemopiSessionState.retainMessages` (`packages/coding-agent/src/mnemopi/state.ts:352`)
always calls `prepareRetentionTranscript(messages, true)` and hands the whole
multi-turn transcript to `embed([transcript])`. Long sessions (especially CJK
content) routinely outgrow the embedding model's context window, and llama.cpp's
`/embeddings` server rejects oversized requests with
`request (N tokens) exceeds the available context size` — every retain after
that point silently lost its vector row, leaving recall on FTS-only.
Capped per-input length inside `embed()` (the single chokepoint every retain /
query / consolidate flow funnels through) at `MNEMOPI_EMBEDDING_MAX_INPUT_CHARS`
(default 32000 chars ≈ 8k English tokens / 16–32k CJK tokens, override via env
or `embeddings.maxInputChars` runtime option; `0` disables). The new array
is allocated only when at least one input is oversized, so the typical short-
query path through `embedQuery` still passes the original array through; the
truncation also emits a debug-or-warn log so the resize is no longer silent.
Fixes#3126
- Replaced usage of `ReturnType<typeof setTimeout>` and `ReturnType<typeof setInterval>` with the explicit `Timer` type across the codebase.
- Updated several type definitions and function signatures to use concrete types instead of inferred return types for improved clarity and maintainability.
- Downloaded config.json with tokenizer sidecars when repairing stale fastembed model caches.\n- Treated fastembed Config file missing errors as repairable initializer failures.\n- Extended cache repair coverage for the missing-config state.\n\nFixes #3054
- Preserved fastembed's transitive ONNX Runtime instead of forcing an ABI-mismatched runtime cache install.\n- Repaired stale fastembed model caches by downloading missing tokenizer sidecars from the matching Hugging Face model repo.\n- Added regression coverage for the runtime install plan and tokenizer sidecar repair.\n\nFixes #3054
Removed the env-only remote extraction guard so the runtime-aware remote LLM availability and call path handles config.yml-provided base URLs. Added background extraction coverage for remember(..., { extract: true }) with MNEMOPI_LLM_BASE_URL unset.\n\nFixes #3041
Moved mnemopi's local embedding provider out of the main agent process by
spawning a dedicated `Bun.spawn` child for fastembed + onnxruntime-node. The
agent CLI gains a hidden `__omp_worker_mnemopi_embed` dispatch; `loadMnemopi`
/ `loadMnemopiCore` install the subprocess-backed initializer through the
newly-exposed `setLocalModelInitializer` seam so every `embed()` call
round-trips through IPC instead of loading the NAPI module. The parent
SIGKILLs the child on dispose so the destructor that segfaults Bun on
Windows shutdown (NAPI finalizer at exit on npm installs, `process.dlopen`
constructor at session start on standalone binaries) never runs in any
address space the agent owns. Mirrors the tiny-model fix from #1607.
Adds `smokeTestMnemopiEmbedWorker` to `omp --smoke-test`, a new
`test/issue-3031-repro.test.ts` that pins the spawn/dispatch/signal-exit
contract and forbids re-importing `fastembed-runtime` from the agent surface,
and changelog entries.
Fixes#3031
