The five fault families - -### YANK — viewport snapped to top — NOT fully converged -- **Mechanism:** a live `historyRebuild` fires `CSI 3 J` while the reader is - scrolled up; ED3-snap terminals reset the visible viewport to the top of the - (now-erased) scrollback. -- **Trigger to avoid:** treating an unobservable probe as "at bottom" during - *passive* streaming, or OR-ing an eager-streaming flag into the live ED3 path. -- **Current stance:** never emit ED3 on an unobservable host during passive - streaming; defer and reconcile at a keystroke checkpoint. ConPTY/win32 never - trust the probe at all. - -### CORRUPTION — duplicated / stale rows — NOT fully converged -- **Mechanism:** the flip side of the yank fix. A deferred/repainted frame - leaves rows already committed to native scrollback out of sync with the live - viewport; the scrollback↔viewport seam duplicates (e.g. a 2-row dup, a - streaming-tail dup, or an async-expansion dup). -- **Trigger to avoid:** repainting the viewport over scrollback that still holds - the old copy; a frozen/deferred block whose snapshot no longer matches after - the region above it reflowed; one mutation branch deferring while its mirror - branch repaints. -- **Current stance:** commit only the **stable prefix** line-count to native - history; keep unstable rows out; reconcile drift at the checkpoint; park the - hardware cursor at real content bottom, not padded bottom. - -### FLASH (and invisible-until-resize) — NOT fully converged -- **Two distinct causes, one symptom:** - - *Flash* = eager ED3 rebuild wrapped in DEC 2026 BSU/ESU fired per streaming - frame on a terminal that clamps scroll on ED3 (VTE/GNOME family). - - *Invisible-until-resize* = the defer fix over-firing, so a structural frame - emits **zero bytes** (`deferredMutation` returns nothing) until a resize - forces a repaint. -- **Trigger to avoid:** env-detection that misses a flashing terminal (SSH - strips `VTE_VERSION`; some hosts set no distinguishing var); collapsing an - `undefined` probe into a definite scrolled/at-bottom verdict. -- **Current stance:** confine ED3 to the destructive path; auto-disable DEC 2026 - at runtime when the terminal reports it unsupported (DECRQM), with - `PI_NO_SYNC_OUTPUT` as a manual hatch; keep autowrap discipline regardless. - -### WIDTH — measurement crashes / fidelity — crash class dead, accuracy unproven -- **Mechanism:** the measured column width of a line disagreed with the - terminal's painted cells (emoji, wide graphemes, combining marks, Hangul - jamo), and the old render loop **threw** on any mismatch — a 1-cell cosmetic - error became a fatal whole-agent crash. -- **Current stance:** **never throw in the render hot path — clamp.** The loop - truncates over-wide lines with `truncateToWidth`/`sliceByColumn` and logs - (under debug) instead of dying. Width is owned end-to-end by one native UAX#11 - engine shared by measure/slice/wrap (see §6). Accuracy across all scripts - (e.g. RTL/combining marks) is still not proven by a green gate. - -### PROBE — stray bytes injected as keystrokes — RESOLVED -- **Mechanism:** a private-CSI probe reply (DA1 / kitty / mode 2031) split - across a stdin flush; the unmatched prefix was dropped and the continuation - bytes were forwarded as keystrokes. -- **Current stance:** buffer-and-reassemble partial CSI responses; give each - probe a typed sentinel owner.

The gateway's encode stream also emits `ping` keepalives every 15s and a complete `message_start`/`message_delta`/`message_stop` envelope when the inner stream ends without a terminal event, so strict clients no longer classify slow or empty streams as protocol errors. +- Fixed the Mistral `requiresThinkingAsText` replay path calling `.unshift()` on string assistant content — an unconditional TypeError that failed any same-model history turn carrying both thinking and text. +- Fixed the Responses gateway stripping `encrypted_content` from inbound reasoning items (strip-mode schema), which broke codex-style stateless replay; the schema is now loose, restoring the symmetry the outbound encoder already preserved. Composite internal `callId|itemId` ids are also split before hitting the wire so third-party clients that validate `call_id` charsets no longer reject them. +- Ported the shared unfinished-tool-call sweep to the codex `response.completed` handler, so a lost `output_item.done` can no longer persist a tool call with stale `{}` arguments and transient parser fields into session history. +- Fixed live text freezing until item completion when a lossy proxy drops `content_part.added`: the missing part is now synthesized on the first `output_text`/`refusal` delta (shared and codex decoders). +- Fixed interleaved `content`/`tool_calls` deltas fragmenting a tool call into a truncated call plus a nameless phantom: text/thinking transitions no longer finish open tool-call blocks, so index-only continuation deltas re-find them. +- Fixed the Azure chat-completions path ignoring `AZURE_OPENAI_DEPLOYMENT_NAME_MAP` (only the Responses provider honored it), producing opaque 404s when deployment names differ from catalog model ids. +- Fixed the chat gateway discarding inbound assistant `reasoning_content`, which fed DeepSeek/Kimi exact-replay upstreams a placeholder instead of the model's actual reasoning; it now round-trips as a thinking block, and `toolcall_end` emits a corrective id/name chunk when the streamed start carried empty values. +- Fixed the auth retry loop minting OAuth tokens and firing a doomed request after the caller aborted, and stopped masking resolver failures (broker/network/refresh errors) as "No API key" — the actual cause is preserved. +- Fixed `EventStream.end()` without a terminal result leaving `.result()` pending forever (reachable via extension streams and the lazy wrapper); it now rejects with a synthesized error. +- Fixed the Copilot retry wrapper blind-retrying every retryable error with fixed 400ms delays: 429/5xx now honor `Retry-After` (capped at 30s) and other statuses are not retried, while status-less transport blips keep the linear retry. +- Fixed the OpenAI completions error path ending the stream without closing open text/thinking/tool-call blocks, leaving consumers with orphaned block lifecycles on every stream error or idle-timeout abort. +- Fixed DSML hold-back freezing display on any bare `<` in model output for up to 256 chars: idle-state holding now only triggers on a strict DSML section-open prefix, and blowing the 1MB parameter cap no longer leaks the closing envelope tags as visible text; a capped parameter value also carries an explicit `…[parameter truncated]` marker instead of executing the tool with silently corrupted input. +- Fixed schema normalization blanking DAG-shared subtrees to `{}`: the visited-set cycle guard treated a subschema object reused across two properties as a cycle; path-tracking `enter`/`exit` now allows sharing while still short-circuiting true cycles, frozen input schemas no longer throw, and the path counter no longer leaks depth on the cycle branch (which made every later normalization of the same object misreport a cycle). +- Fixed shared in-flight Google token refreshes being bound to the first caller's `AbortSignal`, failing every concurrent waiter when one parallel Vertex call was cancelled; callers now race their own signal against a detached refresh, which is bounded by its own 30s timeout so a hung fetch cannot pin the in-flight slot until process restart. +- Fixed Gemini <3 multimodal tool results breaking the single-function-response-turn invariant for parallel tool calls (image turns are buffered and flushed after the merged functionResponse turn), and the gemini-cli consumer now defaults missing `functionCall.args` to `{}` like the shared consumer. +- Fixed Bedrock dropping `toolConfig` entirely when `toolChoice` is `"none"` while history still contains tool blocks — the Converse API rejects such requests, so tool specs are kept and only the choice is omitted. +- Fixed AWS credential handling serving expired credentials until process restart: cache entries are invalidated on 401/403, file-sourced session-token credentials get a 5-minute TTL, and concurrent first requests single-flight instead of spawning duplicate `credential_process`/SSO fetches — the shared resolution is detached from the first caller's abort signal (one cancelled request no longer fails every waiter) and bounded by its own 30s timeout. The eventstream reader also cancels the response body on abnormal exit instead of leaving the HTTP connection draining. + +### Removed + +- Removed the dead `iterateUntilAbort` helper (superseded by `iterateWithIdleTimeout`); it leaked the upstream iterator when the consumer abandoned mid-yield and had no production call sites. + +## [15.10.10] - 2026-06-09 + +### Added + +- Exported `wrapFetchForCch` so non-streaming OAuth callers (e.g. the web-search provider) can patch the Claude Code billing-header `cch` attestation into their request bodies instead of shipping the `cch=00000` placeholder. + +### Fixed + +- Fixed an unbounded, zero-backoff Codex WebSocket reconnect loop on `websocket_connection_limit_reached`: the no-content reconnect path never consulted the retry budget and never waited, hammering the endpoint forever when the limit is account-scoped. Reconnects are now budgeted and delayed like every other WS retry path, falling back to a single SSE replay when exhausted. +- Fixed the Codex whitespace-loop breaker not observing degenerate frames that arrive after their item closed (or before it opened) — those frames count as stream progress, so the idle watchdogs never fired and the turn hung forever, which is exactly the failure mode the breaker exists for. Whitespace-loop recovery now also refuses to replay the turn once a `toolcall_end` was delivered, surfacing the error instead of re-emitting the same tool calls. +- Fixed the two remaining Codex retry paths (WS mid-stream reconnect and the empty-content SSE fallback) leaking blockless native output items (e.g. `web_search_call`) from the failed attempt into the replayed turn's `providerPayload` and append baseline. +- Fixed Codex WebSocket failure handling closing whatever connection currently occupies the session slot — including a concurrent caller's in-flight CONNECTING handshake, whose rejection (`websocket closed before open`) is classified fatal and disabled WebSockets for the whole session. Failure cleanup now skips CONNECTING sockets and the pool re-joins replacement handshakes (bounded). +- Fixed the Codex request transformer not repairing orphan `custom_tool_call_output` items (only `function_call_output` was folded into an assistant note) — a compaction splice that dropped an `apply_patch` call while keeping its result produced a hard 400 on the default GPT-5 Codex toolset. +- Fixed `processResponsesStream` finalizing reasoning items via a bare `itemId` content scan instead of the routed entry: with id-less reasoning items (local hosts), every `output_item.done` matched the FIRST thinking block — the second item's text clobbered it and the second block was never finalized or signed. +- Fixed `processResponsesStream` dropping tool calls and message text whose `output_item.added` event was lost (lossy proxies): `toolcall_end` was emitted with a dangling contentIndex while the call never entered `message.content`, so the agent loop silently never executed it. The done handler now synthesizes the missing block; still-open tool-call blocks are also final-parsed at `response.completed` so the `toolUse` override cannot hand the agent stale `{}` arguments. +- Fixed `response.incomplete` with `incomplete_details.reason: "content_filter"` being reported as a token-cap truncation (`stopReason: "length"`) — the agent loop's length recovery then asked the model to "shorten" a filtered prompt. Content-filtered turns now surface as errors; usage is also populated from `response.failed` events, and an unknown terminal status degrades to `"stop"` with a logged anomaly instead of throwing away a fully-streamed response. +- Fixed Copilot `premiumRequests` accounting being dropped from failed/cancelled responses: `populateResponsesUsageFromResponse` replaced `usage` wholesale and the error path threw before the success-path re-apply. The populate now preserves the field. +- Fixed `deduplicateToolCallIds` suffixing the whole composite Responses id (`callId|itemId`) — `normalizeResponsesToolCallId` extracts the first segment as the wire `call_id` at encode time, so both copies collapsed back onto one `call_id` and the request carried duplicate call/output pairs. The suffix and length budget now apply per segment. +- Gated native history payload replay on api + model id in both Responses providers: after a mid-session model switch, reasoning items carrying encrypted content minted by the previous model were replayed verbatim under the new model. Replay now falls back to block re-encode (which already strips foreign signatures), matching `transformMessages`' same-model trust rule. +- Fixed Azure OpenAI Responses requests omitting `store: false` while requesting `reasoning.encrypted_content` (stateless-only per OpenAI), replaying custom tool calls paired with mismatched `function_call_output` items (customCallIds was never threaded through), letting the SDK's internal retries (maxRetries 5) silently re-POST inside the explicit first-event deadline, and sending a `prompt_cache_key` when the caller opted out via `cacheRetention: "none"`. +- Fixed strict-pairing Responses backends (Azure, Copilot) silently discarding tool results whose call is absent from history — the result is now folded into an assistant note (same shape as orphan-output repair) so the model keeps the information. +- Fixed the OpenAI Responses first-event watchdog staying armed across the `onResponse` notification callback (a slow callback aborted an already-connected stream), Copilot transient-model retries re-attempting on an already-aborted signal (instant dead retry surfacing the scheduler's AbortError), Codex `reasoningSummary: null` being coerced to `"auto"` (the documented omit-summary contract was unreachable), nested Codex error codes (`response.error.code`) being invisible to the connection-limit/previous-response recovery matchers, and the session id leaking unredacted into `PI_CODEX_DEBUG` logs via the `x-client-request-id` header. +- Fixed `processResponsesStream` (shared by `openai-responses` and `azure-openai-responses`) ignoring the terminal `response.incomplete` event: a max-output-tokens-truncated response ended with `stopReason: "stop"`, zero usage, and no cost instead of `"length"` with the reported token counts. `response.incomplete` is now handled alongside `response.completed` and counts as stream progress for the idle watchdogs. +- Fixed custom tool-call content blocks keeping the transient `partialJson` accumulation buffer (and a potentially stale `arguments.input`) after `response.output_item.done` in the shared Responses stream processor — the function_call branch already cleaned these up. +- Fixed two OpenAI Codex stream-retry paths (whitespace-loop recovery and retryable provider errors) leaking native output items from the abandoned attempt into the replayed turn's `providerPayload` — stale reasoning items completed before the failure were re-sent as history input on subsequent requests alongside the retry's own items. +- Fixed the Codex WebSocket queue wiping already-received frames when a transport error arrived: a `response.completed` queued just before an eager server close was discarded, turning a finished response into a spurious `websocket closed` failure and a full request replay. Errors now append behind pending data frames. +- Fixed concurrent `getOrCreateCodexWebSocketConnection` callers (prewarm racing the first request) tearing down each other's in-flight handshake — closing a CONNECTING socket rejected the other caller with a fatal `websocket closed before open`, disabling WebSockets for the entire session. Callers now join the pending handshake. +- Stopped the Codex connection-limit recovery from replaying a turn over SSE after a `toolcall_end` had already been delivered to the consumer (`canSafelyReplayWebsocketOverSse` guard was bypassed, re-emitting the same tool calls); the error now surfaces instead. +- Extended the Codex whitespace-only argument-delta circuit breaker to `custom_tool_call_input.delta` frames, which counted as stream progress and could keep a degenerate response alive forever with no cap on buffer growth. +- Fixed Codex stream failures during transport open reporting a synthetic request dump (empty URL/body) instead of the real request, and a `response.created` event resetting the recorded time-to-first-token. +- Fixed the Codex WebSocket connect watchdog timer leaking (pinning the event loop for up to 10s) when the request signal aborted before or during the handshake. +- Fixed OpenRouter-hosted Anthropic adaptive reasoning models (Claude Fable/Mythos 5 and Opus 4.6+) so the catalog exposes `xhigh`; Fable/Mythos and Opus 4.7+ requests now map user `high`/`xhigh` onto OpenRouter's Anthropic `xhigh`/`max` effort scale. +- Fixed an unknown Anthropic `stop_reason` failing the whole turn after the response had fully streamed. `mapStopReason` threw on unrecognized values, and since the reason arrives on the trailing `message_delta` the error was unretryable — the live `model_context_window_exceeded` stop reason (default on Sonnet 4.5+) hit this path. It now maps to `length`, and any future unknown reason degrades to a logged anomaly plus a normal `stop` instead of an error. +- Stopped clamping API-key Anthropic requests to Claude Code's 64k output cap. The `CLAUDE_CODE_MAX_OUTPUT_TOKENS` clamp exists to match the OAuth wire fingerprint, but `buildParams` applied it unconditionally, silently halving the output budget of 128k-output models (e.g. Opus 4.8) for API-key callers. OAuth requests keep the clamp. +- Stopped a successful strict-tools fallback from shipping `errorMessage` on a `stopReason: "stop"` assistant message. After a grammar-too-large 400 triggered the non-strict retry, the original 400 text was kept on the final message even when the retry succeeded — consumers that treat `errorMessage` presence as failure (e.g. balance probes) misclassified the turn, and the stale text suppressed later refusal explanations. The fallback is now logged instead. +- Fixed model-supplied `User-Agent` headers being silently dropped on non-OAuth Anthropic requests. `enforcedHeaderKeys` filtered the header out of `modelHeaders` in every branch but only the OAuth branch set one back; the Cloudflare-gateway, bearer-gateway, and `X-Api-Key` branches now forward the caller's value verbatim. +- Stopped sending the `fast-mode-2026-02-01` beta header once a session has learned the endpoint+model rejects fast mode (`fastModeDisabled` provider state), matching the already-dropped `speed` param. +- Stopped `buildAnthropicHeaders` defaulting API-key requests onto the full Claude Code OAuth beta list (`oauth-2025-04-20`, `claude-code-20250219`, …). The `claudeCodeBetas` default is now OAuth-gated, matching the streaming path — the web-search header builder was the only caller hitting the default, so API-key search requests now carry just their own betas (e.g. `web-search-2025-03-05`). An empty `anthropic-beta` header is omitted entirely instead of being sent as an empty string. +- Fixed image-bearing `developer` messages being upgraded to mid-conversation `system` turns on Opus 4.8+/Fable/Mythos 5. System content is text-only on the wire, so a developer turn carrying image blocks in an upgrade-eligible position produced a 400; it now stays a `user` message. +- Fixed a spliced reconnect's second envelope overwriting the completed Anthropic message: `message_delta` was not gated by the terminal-stop flag (content events and duplicate `message_start` were), so the splice's `stop_reason`/usage replaced the finished turn's — a `tool_use` turn could be relabeled `stop`, and the harness then never executed the streamed tool calls. Post-terminal deltas are now logged as envelope anomalies and skipped. +- Fixed a `ping` arriving before `message_start` consuming the Anthropic first-event watchdog: the stall was then classified as a terminal mid-stream idle timeout instead of a retryable first-event timeout. Pings no longer count as the first item but still refresh the idle deadline once content is flowing. +- Fixed Anthropic-compatible proxies that omit `usage`/`delta` objects from `message_start`/`message_delta`/`content_block_*` envelopes crashing the turn with an unretryable `TypeError`; the missing payloads now degrade to logged envelope anomalies like every other malformed-frame case. +- Fixed `applyPromptCaching` placing `cache_control` on `thinking`/`redacted_thinking` blocks — Anthropic rejects that with a 400. A thinking-only assistant turn inside the trailing cache window (e.g. followed by the synthetic `Continue.` pad) no longer receives a breakpoint. +- Fixed consecutive `assistant` params reaching the wire when an empty user/developer turn between two assistant turns was dropped by the converter (e.g. an empty "nudge" submission after a length-truncated reply); Anthropic 400s on non-alternating assistant turns, and the broken triple replayed on every subsequent request. A `user: "Continue."` separator is now inserted, mirroring the trailing-prefill fallback. +- Fixed `supportsAdaptiveThinkingDisplay` misparsing bare dated Opus ids: `claude-opus-4-20250514` (Opus 4.0) parsed as minor `20250514` ≥ 4.7, which silently dropped the `interleaved-thinking-2025-05-14` beta for API-key Opus 4.0 requests. +- Fixed `output_config.effort` shipping without the `effort-2025-11-24` beta on thinking-off requests against adaptive-only Claude models (the effort:"low" pin), and the mid-conversation `system` role shipping without `mid-conversation-system-2026-04-07` on API-key and OAuth-utility requests; both betas are now added whenever the request can carry the corresponding field. +- Fixed GitHub Copilot anthropic-messages requests going out with no `Content-Type` and no `anthropic-version` header — the copilot branch builds its headers from scratch and Bun's fetch does not default `Content-Type` for string bodies. Both headers are now pinned to match every other branch. +- Fixed Anthropic client/provider retry multiplication: with the first-event watchdog disabled (`PI_STREAM_FIRST_EVENT_TIMEOUT_MS=0`), the client's internal `maxRetries: 5` reactivated and stacked with the provider loop's 3 retries — up to 24 wire attempts with double backoff. The provider now pins per-request `maxRetries: 0` unconditionally. +- Fixed `AnthropicMessagesClient` spreading `fetchOptions` after the core request fields, letting a caller-supplied `signal`/`method`/`body` silently disconnect the timeout controller or corrupt the request. Transport extras (TLS) still pass through; core fields now always win. +- Fixed Foundry mTLS/CA material being cached for the process lifetime when the env vars point at files: the cache key now folds in the file mtime so on-disk certificate rotation takes effect. +- Fixed the Claude Code fingerprint version drifting across surfaces: the usage endpoint (`claude-cli/2.1.160`) and OAuth bootstrap (`claude-code/2.1.160`) pinned a stale version while `/v1/messages` reported 2.1.165; both now derive from `claudeCodeVersion`. +- Fixed a system prompt that merely *mentions* `x-anthropic-billing-header:` mid-text suppressing the entire Claude Code system-block injection (billing header, instruction, and cch attestation); the resumed-session guard now anchors with `startsWith`. +- Fixed lone surrogates in cross-API tool-call arguments reaching Anthropic's strict UTF-8 validation: replayed OpenAI/Google-origin `tool_use.input` string leaves are now deep-sanitized with `toWellFormed()`, while same-API Anthropic arguments stay byte-identical to keep prompt-cache prefixes stable. +- Bounded the many-image resize fan-out to 4 concurrent decodes (it previously decoded every oversized image at once, two encode pipelines each — multi-GB transient memory at the 20+-image threshold that activates the feature). +- Fixed `mergeHeaders` merging case-sensitively on the Copilot/client-options path, where a miscased user-configured header (e.g. `authorization` next to the synthesized `Authorization`) survived as two keys that the `Headers` constructor joins comma-separated on the wire. +- Hardened the Anthropic stream lifecycle: prologue failures (e.g. a malformed Copilot credential in `buildCopilotDynamicHeaders`) and error-finalization failures now surface as an `error` event instead of an unhandled rejection that left `stream.result()` hanging forever; the spurious "cch billing placeholder not patched" warning no longer fires when the placeholder only appears in user content. + ## [15.10.9] - 2026-06-09 ### Added diff --git a/packages/ai/package.json b/packages/ai/package.json index e4a1a712e..85015886c 100644 --- a/packages/ai/package.json +++ b/packages/ai/package.json @@ -1,7 +1,7 @@ { "type": "module", "name": "@oh-my-pi/pi-ai", - "version": "15.10.9", + "version": "15.10.10", "description": "Unified LLM API with automatic model discovery and provider configuration", "homepage": "https://omp.sh", "author": "Can Boluk", diff --git a/packages/ai/src/auth-storage.ts b/packages/ai/src/auth-storage.ts index 482d0d65c..da8f571b8 100644 --- a/packages/ai/src/auth-storage.ts +++ b/packages/ai/src/auth-storage.ts @@ -4002,8 +4002,8 @@ export class SqliteAuthCredentialStore implements AuthCredentialStore { return; } - const schemaVersion = this.#readAuthSchemaVersion() ?? this.#inferAuthSchemaVersion(); - const shouldWriteSchemaVersion = schemaVersion <= AUTH_SCHEMA_VERSION; + const recordedVersion = this.#readAuthSchemaVersion(); + const schemaVersion = recordedVersion ?? this.#inferAuthSchemaVersion(); if (schemaVersion > AUTH_SCHEMA_VERSION) { logger.warn("SqliteAuthCredentialStore schema version mismatch", { current: schemaVersion, @@ -4015,7 +4015,9 @@ export class SqliteAuthCredentialStore implements AuthCredentialStore { this.#createAuthCredentialIndexes(); this.#backfillCredentialIdentityKeys(); - if (shouldWriteSchemaVersion) { + // Rewriting an already-current version row is a no-op write transaction + // on every boot; only persist when the recorded version actually changes. + if (recordedVersion !== AUTH_SCHEMA_VERSION && schemaVersion <= AUTH_SCHEMA_VERSION) { this.#writeAuthSchemaVersion(AUTH_SCHEMA_VERSION); } } @@ -4171,9 +4173,13 @@ export class SqliteAuthCredentialStore implements AuthCredentialStore { .all() as AuthRow[]; if (rows.length === 0) return; - const updateIdentity = this.#db.prepare("UPDATE auth_credentials SET identity_key = ?

Each provider section ends with per-window capacity stats ("need: 5h → 3 of 5 accounts"). Flags: `--provider` to filter, `--json` for the broker-shaped report payload, and `--redact` to mask account emails/ids down to a two-char anchor plus a minimal middle-out differentiator (`ca*9*`) for screenshot-safe sharing. +- Startup hangs are now self-diagnosing (speculative fix for the "zero output, hangs even on `omp -h`" report class): a watchdog prints a stderr line every 10s naming the deepest in-flight startup phase (via `logger.openSpanPath()`) until a mode runner takes over, pausing around legitimate interactive waits (fork/move prompts, the `--resume` session picker); `PI_DEBUG_STARTUP` is restored as streaming synchronous `[startup]` phase markers covering command-module imports and the native addon load, which the post-startup `PI_TIMING` tree structurally cannot show for a hang; and waiting on piped-stdin EOF announces itself after 1s instead of blocking silently. + +### Changed + +- Cached custom model alias maps and built them lazily on first custom model reference lookup, avoiding unnecessary startup model-registry initialization +- Cached resolved auth broker configuration and snapshot reads for the process lifetime so repeated startup paths reuse the same `OMP_AUTH_BROKER_*` resolution instead of re-running config/token discovery +- Reused task-agent discovery results for repeated `TaskTool.create` calls in the same working directory to avoid repeated plugin scans during subagent startup +- Tightened the system prompt and tool prompts: deduped restated warnings (bash "catch yourself" list, search/find shell-fallback recaps, read instruction/critical overlap, the AST metavariable primer duplicated across both ast tool descriptions), factored the repeated repo-default clause in the `gh` search ops, dropped a dead `rsed` reference and an internal `tool-timeouts.ts` pointer, and pruned internal mechanism the agent can't act on (screenshot temp-file/downscaling pipeline, browser spawn lifecycle, `gh` "replaces former op" history and run-watch grace period, output-minimizer heuristics, BM25 ranking name, `task.maxConcurrency` pointer) +- Extended the prompt-efficiency pass to the full prompt surface (subagent/plan-mode/notice/title/commit system prompts, agent definitions, goals, memories, review and autoresearch prompts): RFC-keyed prescriptive prose, fixed garbled grammar and a stale `` placeholder in the plan-approval reminder, deduped intra-file restatements, and corrected the `todo` op table's claim that `rm` requires a `task`/`phase` (bare `rm` clears the whole list) +- Replace tool prompt no longer recommends `sed -i`/`cat`-heredoc commands that the bash interceptor blocks; its bash-alternatives table now only lists non-intercepted commands +- Capped concurrent IRC cards in the transcript's live region at 4: cards landing below a still-running tool cannot commit to native scrollback, so an unbounded burst pushed the live block's uncommitted rows above the window top (content read as cut off until the cards expired). The oldest live-region card now retires as soon as a new one would exceed the cap. +- Interactive PTY mode (`pty: true`) no longer injects the non-interactive environment (`TERM=dumb`, `GIT_EDITOR=true`, `PAGER=cat`, `NO_COLOR=1`) that defeated its purpose — the PTY child now gets a real `TERM=xterm-256color`; and when a PTY is requested but unavailable (headless/RPC), the result now carries an explicit downgrade notice instead of silently running through a dumb pipe. +- Raw sqlite `?q=` queries are now capped at 1000 rows with an "add a LIMIT clause" notice — `statement.all()` on a multi-million-row table previously materialized every row, blocking the process for minutes. +- Plain-file range reads no longer scan to EOF on files over 4MB just to count total lines (the count is reported as approximate), and multi-range reads slice from a single pass instead of re-streaming the file once per range. +- `gh run_watch` now polls adaptively (3s for the first minute, then 15s), survives rate-limit errors with backoff instead of dying and discarding accumulated context, reuses job data for completed runs, and gives up with a clear message after ~90s when a commit has no workflow runs at all (previously an infinite 3-second poll loop). +- The legacy patch-mode fuzzy matcher pre-normalizes file and pattern lines once per seek with a Levenshtein lower-bound bail, replacing the per-position re-normalization that made a single mismatched hunk against a 10k-line file cost multi-second synchronous stalls; the streaming hashline preview also caches file text and tree-sitter block resolution across ticks instead of re-reading and re-parsing every target file per streamed chunk. +- The DAP client reader now uses chunk-list buffering and the output buffer is a chunk deque with a running byte count — debugging a chatty program previously cost O(n²) `Buffer.concat` per chunk plus whole-buffer byte-scans per 1KB trim, freezing the session. +- GitHub caching: the per-lookup auth key is memoized against `hosts.yml` mtime (was a blocking `readFileSync` on every `issue://`/`pr://` read including cache hits), background refreshes are deduped by row identity, and PR diffs are stored once per row instead of twice (unified + rendered copies). +- Task progress snapshots shallow-copy per-agent progress instead of `structuredClone`-ing nested tool payloads (up to 500KB) on every progress event; streaming assistant-message reveal caches per-block grapheme counts and skips the markdown render LRU for in-flight partials, eliminating 2-3 full Intl.Segmenter walks per 33ms tick and tens of MB of retained stale partial snapshots on long replies. +- Python eval cells: the availability probe is cached per cwd (was two interpreter spawns per cell even with a hot kernel), and stdout frames coalesce per write instead of one locked+flushed JSON frame each. +- Multi-entry edits now stop at the first failing entry and report exactly which entries were applied and which were not — continuing after a failure applied later entries authored against line numbers that assumed the failed entry succeeded, and a retry of the whole batch then double-applied the survivors. + +### Fixed + +- Fixed the bundled `explore` agent's `thinking-level: med` frontmatter — not a valid effort (`minimal`/`low`/`medium`/`high`/`xhigh`), so it silently parsed to undefined and the agent ran without its intended thinking level +- Discovery context-file reads (`~/.claude`, `~/.cursor`, project trees, `@`-imports) now stat-gate to regular files before reading: a FIFO/socket/char device dropped where a context file is expected previously blocked startup forever on a read that can never see EOF. +- Kept IRC cards from being removed after their TTL once everything above them finalized: their rows may already be committed to native scrollback, and removing them was an interior deletion of the committed prefix that the engine could only repair by recommitting everything below the gap (duplicated blocks). Such cards now stay in the transcript as durable history. +- Fixed the recommit storm that sprayed stale snapshots of a running task's progress tree into native scrollback. The stable-prefix ratchet promoted any row quiet for one 30-frame window, so slowly ticking rows (per-agent tool/cost counters updating every few seconds) were repeatedly promoted, committed, rewritten, and recommitted by the engine audit for the whole run. The ratchet now floors itself permanently at the first row that mutates after being promoted — settled heads (a task's prompt/context) still reach scrollback, genuine tickers never re-promote. +- **Fixed the artifact spill dropping the first ~20KB of output**: head-retained bytes were never written to the artifact file, so for every bash/eval/ssh command exceeding the 50KB spill threshold, the `artifact://` advertised as the "full capture" was permanently missing its head — the agent re-reading it got truncated data presented as lossless. +- Fixed streaming-output chunk throttling dropping chunks instead of coalescing them: streaming previews and the auto-background "output so far" text the model reasons over contained output with arbitrary middles silently spliced out. +- **Fixed `vault://` writes bypassing both the approval ladder and plan mode**: internal-URL writes were uniformly rated tier `read` (auto-allowed even in always-ask) and the internal-router branch returned before the plan-mode guard, so the model could silently overwrite real Obsidian notes; writes through schemes with a mutating handler are now tier `write` and plan-mode-enforced. +- Fixed writes into `.tar.gz`/`.tgz` archives silently stripping gzip compression (the rewritten archive was a bare tar under the `.gz` name — masked on re-read because Bun auto-detects, broken for `tar xzf`/CI consumers), and made archive rewrites atomic via temp-file + rename so a crash mid-write can no longer destroy every other member; symlinked archive paths resolve to their target before the swap so the rename writes through instead of replacing the link with a regular file. +- Fixed merge-conflict detection being completely inert on CRLF files: the scanner split on `\n` and compared `=== "======="`, so `=======\r` never matched and the agent edited around live conflict markers without warning; CRLF files now detect, splice, and round-trip their line endings correctly. +- Fixed cross-line search (`\n` in the pattern) silently returning zero matches: the native searcher was never switched to multi-line mode (only the regex flag was set), so the advertised feature matched nothing on real files while reporting a confident "No matches found". +- Fixed search results lying about completeness: one hot file could consume the entire 2000-match global budget in path order making later files unreachable by any `skip` (now capped per file with the footer hedging `of N+` when truncated), paginating past the last page returned "No matches found" instead of "No more results", directory scans now report how many >4MB files were skipped instead of silently excluding them, adjacent matches in virtual resources no longer emit duplicated backwards-numbered context lines, and patterns are no longer `trim()`ed (only all-whitespace is rejected — leading/trailing whitespace is meaningful regex). +- Fixed the search tool's native grep being uncancellable: neither the abort signal nor any timeout was threaded through, so Esc on a huge-tree search left the native walk burning CPU to completion; both now propagate (30s default timeout). +- Fixed archive and sqlite reads that could OOM or hang the process: tar/tgz archives are stat-gated at 256MB before being loaded, zip members reject attacker-declared uncompressed sizes over 64MB before allocation, and binary plain files now return a NUL-sniff notice instead of filling the line budget with mojibake. +- Fixed malformed internal-URL selectors (`artifact://3:-100`) silently dumping the whole resource instead of erroring, selectors directly on an archive root (`a.zip:500`, `a.zip:raw`) being misparsed as member names, archive members minting editable hashline tags keyed to the archive path (they are immutable resources), URL selector tokens being case-sensitive (`:RAW` 404ed), `artifact://N` resolving into another session's artifacts in multi-session hosts, and not-found paths with archive/sqlite extensions stacking multiple 5s workspace-wide suffix globs (now shared per read, with glob metachars escaped so `foo[1].ts` can match itself). +- Fixed leading `cd X &&` extraction breaking shell-expanded paths — `cd "$(git rev-parse --show-toplevel)" && make` failed with "Working directory does not exist" because the captured path was resolved literally; extraction now defers to the shell when the path contains `$`, backticks, or `(`. +- Fixed the echo/printf write-redirect interceptor rule blocking legitimate commands containing `>` inside quotes (`echo "a -> b"`, `printf 'use 2>&1'`); the rule is now quote-aware, and also catches `>|` clobber redirects and `$VAR` targets it previously missed. +- Fixed every completed auto-backgrounded bash invocation leaking its persistent native `Shell` in the process-global session map, and the running-job cap failing all bash commands outright — at capacity, commands now degrade to direct foreground execution (explicit `async: true` still errors). +- Fixed a duplicate-delivery race where a bash job completing just inside the auto-background threshold could be returned as the tool result and re-injected as a completion notification, and fixed auto-background silently preempting the ACP client-terminal route when an editor advertises terminal capability. +- Fixed timed-out/cancelled PTY and client-bridge commands surfacing raw output with no annotation (the model couldn't distinguish timeout from failure and retried identically); the timeout/abort notice is now always appended. +- Fixed `ask` reporting timeout auto-selection as "User selected: X" — fabricated consent for consequential questions; the result now says "(auto-selected after timeout)" with a `timedOut` detail flag, the transcript card marks the auto-selection distinctly, and a deliberate Esc seconds past the deadline is treated as a cancel instead of being reclassified as a timeout. +- Fixed `todo` accepting duplicate task content/phase names in `init` (duplicates were permanently unaddressable — every targeting op hit the first match while auto-promotion kept resurrecting the twin) and persisting half-applied batches on error; failed batches no longer mutate state. +- Fixed the auto-generated-file guard caching markers by path alone with no invalidation — a file regenerated after first check stayed editable (and vice versa); entries are now validated against mtime+size. +- Fixed editor-bridged (ACP) writes skipping the post-write bookkeeping the direct path performs (`bumpFileMutationVersion`, shebang chmod), so mutation-version consumers saw stale state depending on whether an editor was attached. +- Fixed `conflict://*` resolution failing spuriously when an out-of-band edit shifted a conflict block (stale duplicate registrations are now tolerated as already-resolved — but a DISTINCT conflict block that is merely byte-identical and still present in the file stays addressable), and partial conflict-resolution failures now set `isError` instead of burying failed files mid-text in a success result. +- Fixed patch-mode prefix/substring matches silently truncating line content the model never saw: every non-exact match strategy now emits a warning with strategy + similarity, and prefix/substring matches are rejected unless the discarded fragment survives in the replacement lines. +- Fixed ast-edit and file-mention snapshots being recorded under non-canonical paths (invisible to stale-tag recovery under symlinked cwds), and the ast-edit apply step leaving every just-issued preview tag stale — post-apply snapshots are re-recorded and fresh tags surfaced in the result. +- Fixed notebook cells containing literal `# %% [markdown]` marker text being silently split into extra cells on any edit; marker-shaped source lines are now escaped on render and restored on parse. +- Fixed the LSP client being published before `initialize` completed (concurrent callers hit "server not initialized" flakes on first use), reader-loop death leaving a permanent zombie client where every request times out at 30s forever (bad messages are now isolated per-message and a dead reader tears the client down for respawn), framing stalls on header blocks without `Content-Length` (now resynced past the junk in both LSP and DAP), `lsp status` hardcoding `ready` for every client including wedged ones, and shutdown skipping clients still mid-initialize (their server processes outlived exit). +- Fixed numeric LSP code-action selectors being shadowed by substring title matches — `query: "2"` could apply a *different* quickfix whose title contained "2"; numeric queries now select strictly by index. +- Fixed `file://` URIs built without percent-encoding: a `%` in a path threw `URIError` on round-trip and a `#` truncated the server-side path, desynchronizing diagnostics and workspace edits; URIs from lax servers carrying a raw `#`/`?` now route to the lenient parser instead of parsing "successfully" as fragment/query and misrouting edits. +- Fixed multiple LSP inserts at the same position applying in reverse of spec order (transposed import/reference insertions), and `applyWorkspaceEdit` now overlap-validates every file before writing any, so a conflicting rename no longer leaves the workspace half-renamed. +- Fixed `lsp reload` hanging for the whole tool timeout (`didChangeConfiguration` was sent as a request; it is a notification), biome failures being silently reported as "no diagnostics", a hung language server adding up to 30s to every edit (writethrough init is now deadline-bounded at 5s with deterministic spawn failures negative-cached for 3 minutes), and DAP `pause()` burning its full timeout when the stopped event raced the subscription; concurrent DAP breakpoint mutations are also serialized per session (last-writer no longer silently drops the other's breakpoints), queued mutations honor the caller's abort at dequeue, and the DAP output buffer retains a full 128KB tail instead of dropping whole chunks below the cap. +- **Fixed concurrent isolated background tasks interleaving `git stash push/pop` + cherry-pick on the shared repository** — the merge sequence now runs under the repo lock, eliminating a lost-uncommitted-changes race; a stash-pop failure after successful cherry-picks also no longer reports merged branches as "unmerged" (the duplicate-commit trap) and instead tells the user to pop the stash manually. +- Fixed async task batches getting stuck "running" forever (unscheduled/failed-to-register tasks never counted toward completion), error-result jobs being marked `completed`, semaphore-queued tasks counting against the 15-job global cap (batches >15 dropped the remainder and starved other async work), duplicate task ids skipping validation on the async path, and an abort racing subagent session startup leaking the late-created session's LSP/MCP processes. +- Fixed task fail-fast abandoning in-flight siblings uncancelled (the worker signal now propagates), patch-mode merges blocking ALL successful siblings' patches when one task failed, and `$@` command expansion interpreting `$`-replacement patterns in user input. +- Fixed eval cells double-writing artifacts (the tool and the per-cell executor each opened a sink on the same artifact path, corrupting >50KB outputs), JS `parallel()` early-rejecting in violation of its documented barrier (orphaning in-flight `agent()` thunks with worker-side promises hung forever), Python child subprocesses inheriting the NDJSON frame pipe (their stdout was dropped and could corrupt protocol frames — it is now captured and forwarded), JS cell timeouts silently wiping persistent VM state without annotation, and the JS console bridge throwing on `console.dir`/`time`/`group`/`assert`/`trace`. +- Fixed `pr_push` never invalidating the PR/diff cache (the canonical push-then-verify flow read a pre-push diff for up to 5 minutes), current-branch `gh pr merge`/`close` with no positional never invalidating at all (exactly the staleness the cache layer claims to eliminate; numeric flag values like `--milestone 3` also no longer steal the positional), multi-PR checkouts discarding successful checkouts and racing in-flight git mutations on first failure (`allSettled` with per-PR reporting), run-watch ending with a failure result and zero logs when an auto-retry raced the grace-period refetch, the per-watch completed-run job cache serving a rerun's FIRST-attempt jobs after the rerun completed (entries are evicted whenever a run is observed non-completed), pagination terminating on post-filter page length, millisecond precision leaking into GitHub search date qualifiers, leading-dash PR identifiers reaching `gh` as flags, and `issue://?state=` typos silently coercing to the open list. +- **Fixed the Exa API key being written to the log file** on every failed MCP request (the key rode the query string of logged URLs; key/token/secret/auth params are now redacted), and **removed the web-search query rewrite that replaced every `202x` substring with the current year** — it corrupted CVE identifiers and made historical-year searches silently impossible. +- Fixed reopening the sole browser tab with a different `dialogs` policy disposing Chromium and then using the dead handle, a stale tab release evicting a live replacement browser from the registry (spawning duplicate Chromium processes), and concurrent same-name `open` calls leaking a worker + refcount via a check-then-set race (acquisitions are now single-flight per name); queued opens honor an abort at dequeue, and an init-payload failure releases the temporary browser hold instead of pinning the refcount forever. +- Fixed fetch decoding every response as UTF-8 regardless of declared charset (Shift_JIS/EUC-KR/GBK pages rendered as mojibake through the whole reader pipeline; `Content-Type` and `` are now honored via `TextDecoder`), binary URLs being downloaded twice (body skipped on the first pass for convertible types), >50MB truncation being silent (now flagged in notes), all transport error detail being swallowed into a bare "Failed to fetch URL" (the cause is surfaced and 429s get one `Retry-After`-honoring, abort-aware retry), MCP SSE keep-alive lines escaping as raw `SyntaxError`s, MCP calls having no default timeout (now 60s), and a YouTube fetch budget expiry being misreported as a user abort that also skipped temp-file cleanup. +- Fixed archive directory listings silently ignoring the selector offset — `a.zip:dir:50` now starts the listing at the 50th entry instead of relisting from the top. + +## [15.10.10] - 2026-06-09 + +### Added + +- Added a read-only `view` op to the `todo` tool that echoes the current list without mutating state, so the agent can recover exact task text instead of guessing it from memory. + +### Changed + +- Rewrote the bash tool's coreutils guidance (tool prompt and system prompt) around an explicit litmus: pipelines that compute a new fact (`wc -l`, `sort | uniq -c`, `comm`, `diff`) are legitimate bash, while commands that merely move, page, or trim bytes a dedicated tool can fetch remain banned — output trimming destroys data the `artifact://` capture would have saved. + +### Fixed + +- Fixed the model selector dropping an immediate Enter when cached models were available but the selector's offline refresh was still pending. +- Fixed dynamic `import(...)` inside functions passed to the browser tool's `tab.evaluate`/`page.evaluate` failing with `__omp_import__ is not defined`. The eval/browser JS runtime rewrites dynamic-import callees to the worker-injected `__omp_import__` helper, but puppeteer serializes evaluate callbacks with `Function.prototype.toString()` and re-runs them inside the page, where the helper does not exist. The rewriter now substitutes a guarded shim that falls back to native dynamic import when the helper is absent, so serialized code works in the page realm while in-worker imports keep resolving against the session cwd. +- Transcript block freezing is now unconditional instead of gated on ED3-risk terminal detection: every finalized block replays its frozen snapshot once it crosses out of the live region, on all terminals including Windows, because the rewritten renderer's committed scrollback is immutable everywhere. Still-mutating blocks (pending tools, streaming messages, async thinking renderers) anchor the live region and keep repainting until they finalize, which structurally fixes stale/duplicated output from late async expansions ([#1823](https://github.com/can1357/oh-my-pi/issues/1823)). +- Fixed the edit tool's post-edit diff preview occasionally echoing a context line twice with out-of-order numbering. Block-boundary context injection classified space-prefixed diff rows as old-file-only, so an unchanged line sitting in a net-offset region (old N / new N+k) was missing from the new file's visibility window; `findBlockContextLines` then re-surfaced it under its post-edit number and the row was spliced in after the adjacent change run. New-file boundary lines are now translated back to pre-edit numbers (the compact-preview renumbering contract) and merged into a single old-numbered insertion pass — also fixing closers below a net-offset edit being dropped or renumbered incorrectly. +- Fixed the Anthropic web-search provider claiming the Claude Code identity on API-key requests: the CC billing header + system instruction were injected whenever the model wasn't Haiku 3.5, regardless of auth mode. Injection is now OAuth-gated like the streaming path, and OAuth search requests patch the billing header's `cch` attestation (via `wrapFetchForCch`) instead of shipping the `cch=00000` placeholder. +- Fixed long streamed content appearing cut off mid-run: scrolled-off rows were erased from the viewport without ever being appended to terminal history. The transcript's commit boundary (`deriveLiveCommitState`) was all-or-nothing per block — one perpetually rewriting row (a task tool's ticking progress tree, per-agent cost/tool counters, spinner stats) suspended scrollback commits for the entire block, so once the block outgrew the viewport its static head (e.g. a task's prompt/context markdown) was neither committed nor on screen until the tool sealed, and was lost outright if the session ended mid-run. A stable-prefix ratchet now promotes leading rows that stayed visibly identical for a full 30-frame window as commit-safe, so the settled head reaches native scrollback while only the genuinely volatile tail stays deferred; a rewrite above the promoted run retreats the boundary and the engine audit recommits (duplication, never loss). +- Fixed local tiny-title worker stdout/stderr leaking raw native model output such as `` and cache/status lines into the interactive TUI scrollback ([#2206](https://github.com/can1357/oh-my-pi/issues/2206)). +- Fixed task-agent discovery advertising Claude Code custom agents from `.claude/agents/*.md` as OMP subagents; direct task-agent discovery now only loads OMP-native `.omp` agent roots, while Claude marketplace plugin agents keep their existing provider path ([#2209](https://github.com/can1357/oh-my-pi/issues/2209)). + +### Removed + +- Removed the `clearOnShrink` setting and its `PI_CLEAR_ON_SHRINK` environment variable: the rewritten renderer always clears shrunken rows exactly, so the flicker/perf tradeoff the setting controlled no longer exists. Existing config entries are ignored. +- Removed the prompt-submit native-scrollback reconciliation checkpoint and the eager streaming render mode from the interactive controllers — the renderer's append-only contract made both obsolete. ## [15.10.9] - 2026-06-09 @@ -9813,4 +9905,4 @@ Initial public release. - Git branch display in footer - Message queueing during streaming responses - OAuth integration for Gmail and Google Calendar access -- HTML export with syntax highlighting and collapsible sections +- HTML export with syntax highlighting and collapsible sections \ No newline at end of file diff --git a/packages/coding-agent/package.json b/packages/coding-agent/package.json index b69b067f5..bbb30e6ee 100644 --- a/packages/coding-agent/package.json +++ b/packages/coding-agent/package.json @@ -1,7 +1,7 @@ { "type": "module", "name": "@oh-my-pi/pi-coding-agent", - "version": "15.10.9", + "version": "15.10.10", "description": "Coding agent CLI with read, bash, edit, write tools and session management", "homepage": "https://omp.sh", "author": "Can Boluk", diff --git a/packages/coding-agent/src/async/job-manager.ts b/packages/coding-agent/src/async/job-manager.ts index e1ef6a365..58f05f61f 100644 --- a/packages/coding-agent/src/async/job-manager.ts +++ b/packages/coding-agent/src/async/job-manager.ts @@ -23,6 +23,12 @@ export interface AsyncJob { * supply an id (e.g. legacy tests, SDK consumers without an agent context). */ ownerId?: string; + /** + * Job is registered but parked behind a caller-managed gate (e.g. a task + * batch semaphore).

movement now walks graphemes and snaps the target offset to a cluster boundary, also fixing column drift across wide glyphs +- Fixed cursor positions inside whitespace trimmed at a word-wrap boundary mapping to no layout line — the cursor vanished and the viewport jumped to the buffer's last line; the preceding chunk now owns the skipped whitespace run +- Fixed word-delete and kill-to-line operations (Ctrl+W/Alt+D/Ctrl+U/Ctrl+K) cutting through atomic paste markers, leaving `[Paste #1, +30` junk that no longer expanded to the pasted content on submit — delete ranges now extend over any atomic token they intersect +- Fixed the kitty CSI-u printable dedup swallowing a real keystroke arbitrarily long after the duplicated event; the pending codepoint now expires after 25ms +- Fixed `resetDisplay()` being a no-op on the alt screen: the redraw gesture could not repair a corrupted fullscreen modal because `#emitAltFrame` skipped identical-string repaints without consulting the force-repaint flag +- Fixed the ghostty initial-image paint deferral consuming resize/cursor state before abandoning the frame, which could misclassify the deferred render's reflow and corrupt the paint — the deferral check now runs before any frame state is touched +- Fixed the terminal-cursor inline-hint branch adding the full hint width to the line accounting even though the rendered hint was truncated, misaligning right padding whenever the hint overflowed +- Fixed nested markdown list detection sniffing for hardcoded `\x1b[36m` (chalk cyan): every shipped theme emits truecolor/256-color SGR for bullets, so nested items doubled their indentation per level on all real themes;

The engine now audits its committed prefix every ordinary frame: an in-place edit or restyle keeps its alignment (stale styling in history remains the accepted artifact), while any shift re-anchors the commit index at the first moved row and recommits from there — history keeps the stale copy and gains a fresh one. Duplication, never loss. The detector (`findCommittedPrefixResync`, exported for the stress harness's shadow ledger) samples the prefix tail SGR-stripped so theme restyles and single-row edits never trigger spurious recommits. +- Fixed budget-demoted inline images shrinking their transcript block: the text fallback is now height-preserving once a graphic has rendered (reserved rows plus the fallback line), so demotion never shifts content below a committed image. +- Fixed stale trailing cells bleeding into committed history on combining-heavy rows: the native width model can over-count Arabic/combining clusters, classifying a short-rendering row as full-width and skipping the trailing erase — the previous occupant's cells then scrolled into scrollback baked into the committed row. Non-ASCII row rewrites now erase the line before writing. + +### Changed + +- Rewrote the render core around an append-only native-scrollback contract. Committed rows are immutable: rows enter terminal history exactly once, in order, when the component-reported commit boundary (`NativeScrollbackLiveRegion`) marks them final, and the visible window repaints in place with relative moves. The engine no longer probes the terminal's scroll position or guesses whether a destructive rebuild is safe — the entire ED3-risk/defer/checkpoint machinery (viewport probes, eager streaming mode, dirty-scrollback reconciliation, deferred shrink/mutation intents, streaming high-water rebuilds, ConPTY-specific defer paths) is deleted. ED3 (`CSI 3 J`) now fires only on explicit user gestures: session replace, resize outside multiplexers, and `resetDisplay()`. This structurally removes the yank / flash / duplicated-rows / invisible-until-resize failure families tracked across #1610, #1635, #1651, #1682, #1719, #1746, #1799, #1823, #1962, #1974, #2000, #2011, #2154. +- A frame that shrinks into its committed prefix re-anchors the visible window at the new tail and restarts commit bookkeeping; previously committed rows stay in history (history is never rewritten without a gesture). +- Overlays now composite into the visible window slice only and freeze commits while visible, so overlay pixels can never enter native scrollback and closing an overlay no longer triggers a destructive history rebuild. +- Inline-image budget demotion now deletes the demoted image's graphics by id and lets the window diff repaint the text fallback — no more mid-session destructive full replay when the image cap is exceeded. +- The render-stress harness now validates the contract with a shadow commit ledger (an independent reimplementation of the ledger math fed only by observed frames and bytes), asserting scrollback equals the committed prefix row-for-row and that tape growth matches physical scroll exactly, across randomized op sequences, resizes, overlays, and multiplexer scenarios. The ghostty-web virtual terminal additionally survives libghostty-vt 0.4's WASM allocator traps via an event-log replay/compaction recovery, and strips non-spacing combining marks on input (a margin-aligned combining cluster deterministically corrupts that engine; mark placement through it was already unverifiable). + +### Removed + +- Removed the probe/defer API surface: `TUI.setEagerNativeScrollbackRebuild()`, `TUI.refreshNativeScrollbackIfDirty()`, `TUI.setClearOnShrink()`/`getClearOnShrink()`, `RenderRequestOptions.allowUnknownViewportMutation`, `NativeScrollbackRefreshOptions`, `Terminal.isNativeViewportAtBottom()`, `Terminal.hasEagerEraseScrollbackRisk()`, and the `eagerEraseScrollbackRisk`/`submitPinsViewportToTail` capability fields with their detectors. +- Removed the `PI_TUI_ED3_SAFE`, `PI_CLEAR_ON_SHRINK`, and `PI_TUI_DEBUG` environment variables (the levers they tuned no longer exist; `PI_DEBUG_REDRAW` now logs the commit-ledger state per frame). + ## [15.10.9] - 2026-06-09 ### Added @@ -1228,4 +1268,4 @@ Initial release under @oh-my-pi scope.
