- Lifted the unknown-incremental-label check above the !useLastTurn guard so type: [findings], result: {} also rejects, preventing a sibling section's MAX_SCHEMA_RETRIES override from sneaking the stale section through finalization.\n- Extended the regression test with the last-turn payload case.\n\nRefs #3926
- Made unknown incremental yield labels under a closed caller schema throw on every call without consuming MAX_SCHEMA_RETRIES, so the post-mortem override no longer accepts the stale-label payload.\n- Strengthened the regression test to assert the hard failure repeats and the schema-retry budget stays intact for legitimate shape mismatches.\n\nRefs #3926
- Rejected unknown incremental yield labels when the active output schema is closed, so caller override schemas fail in-tool with retry feedback instead of post-mortem schema_violation.\n- Added regression coverage for reviewer-native labels under a caller override schema.\n\nFixes #3926
Normalized string-encoded JSON arrays in grep/search path handling so direct execute paths match validated tool-call behavior.
Added regression coverage for direct GrepTool.execute paths supplied as a JSON-array-shaped string.
Fixes#3873
The yield tool's per-call schema validator was skipped entirely for incremental
yields (`type: ["<label>"]`), so when a subagent emitted a non-conforming value
for a known section (e.g. DeepSeek-v4-pro returning "Correct"/"correct."/"approved"
for the reviewer's `overall_correctness` enum), the call succeeded locally and
the model got no retry feedback. The mismatch only surfaced post-mortem in
`finalizeSubprocessOutput` as a fatal `schema_violation` — the parent agent
lost the entire result, with no recourse for the subagent to fix it.
Build a per-label sub-validator map alongside the full-schema validator: each
entry validates one section's `data` against its top-level property's sub-schema
(items schema for array-typed labels like `findings`). The yield tool runs this
map for incremental yields and routes failures through the same MAX_SCHEMA_RETRIES
budget the terminal path uses, so the model sees up to three corrective retries
and the existing schema-override safety net accepts the value with
SUBAGENT_WARNING_SCHEMA_OVERRIDDEN after exhaustion. Unknown labels remain
unconstrained so scratchpad/streaming sections still pass.
Fixes#3870
- Migrated global service tier settings to a per-model-family architecture (OpenAI, Anthropic, Google).
- Implemented `ServiceTierByFamily` mapping to allow independent configuration and resolution per provider.
- Added automatic migration logic for legacy service tier and fast-mode application settings.
- Updated telemetry, session management, and task execution to support provider-specific tier resolution.
- Introduced `isProbablyBinary` utility to sniff file headers for NUL bytes or invalid UTF-8 sequences.
- Updated `ReadTool` to use the binary sniffer, preventing mojibake corruption in output when reading non-text files.

- Added comprehensive unit tests for binary detection logic, covering NUL bytes, truncated multibyte characters, and path-based file sniffing.
- Always remove surfaced irc:incoming records from the pending-aside queue; the inbox tool result already injects the body, so leaving them queued would auto-inject a duplicate at the next step.
- Updated the inbox tool to drain pending asides regardless of peek.
- Added a regression test asserting a peeked pending aside does not auto-inject.
- Drained running-session IRC asides through the inbox tool before the model step consumes them.
- Added a regression test for messages delivered while the recipient is already running.
Fixes#3834
Rejoined split Windows extension module paths before launch parsing finishes and stripped extended-length Win32 prefixes before Bun import and worker spawn APIs see them.
Fixes#3804
- Adjusted hashline header formatting to preserve absolute file paths instead of truncating them to basenames.
- Ensured absolute paths are passed through shortenPath to allow resolution while keeping home directory references concise.
- Prevented edit failures when reading files outside the workspace by ensuring tags remain resolvable.
- Added missing `noteDisplayableThinkingContent` mock function to test fixtures.
- Included `markActivityStart` and `markActivityEnd` methods in status line mocks to match updated controller interfaces.
The SSH renderer previously declared 'provisionalPendingPreview: "collapsed"',
which only opted the COLLAPSED pending shape out of the transcript's
stable-prefix ratchet. Once the user expanded an in-flight SSH preview (ctrl+o)
and the framed block outgrew the viewport, the pending rows became
ratchet-eligible and committed to native scrollback before the result render
inserted the 'Output' section. The settled render then re-anchored the frame,
producing two distinct stranded shapes in history:
- a stale 'pending SSH: [host]' header pinned above the final '<- SSH: [host]'
frame (header variant), and
- the pending bottom border row reused in-place as the new 'Output' separator,
with a fresh '...' footer pushed below it (footer variant).
Flip 'provisionalPendingPreview' to 'true' so every pending shape — collapsed
or expanded — is treated as provisional and stays out of native scrollback
until the result render commits a settled frame. The 'collapsed'-only opt-out
remains correct for renderers (bash, eval) whose expanded pending preview is
top-anchored and survives the result render without re-anchoring.
Added two contract tests asserting expanded pending SSH is commit-unstable
and that bash/eval expanded pending preview is still commit-stable — keeping
the opt-in renderer-scoped.

Fixes#3660
- 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.

- Applied the new formatter across record and display functions in the read tool.
- Added and updated tests to verify that hashline headers now contain only the filename for nested files.
- Renamed the `find` and `search` tools to `glob` and `grep` respectively across the codebase to improve command clarity.
- Implemented full-stack support for the renamed tools, including CLI arguments, system prompts, SDK exports, and tool registration.

- Updated the `collab-web` renderer registry to ensure backwards compatibility with legacy tool outputs.
- Removed the enforced minimum length for the `items` array in the tool schema to prevent unnecessary validation errors on operations that ignore the field.
- Added tests to verify schema acceptance of empty `items` arrays and confirmed that runtime errors are still correctly thrown for empty inputs during specific operations like `append`.
- Suppressed main-UI relay for sibling broadcast legs when the main agent is a direct target.
- Added `suppressRelay` option to `IrcBus.send` to allow selective disabling of relay rendering.
- Ensured broadcast fan-outs avoid rendering the same message twice in the main transcript.
The >4 MiB JS fallback re-introduced regex-dialect divergence by size. Oversized line-mode virtual resources are now searched in line-boundary chunks (each <= NATIVE_GREP_MAX_FILE_BYTES) through native grep, with matched line numbers offset by each chunk's start, so RE2 dialect parity holds for all line-mode sizes. A single line larger than the cap (un-grepable) is JS-tested individually. Multiline keeps the JS fallback, since chunk boundaries would drop cross-line matches. Test now proves (?i)NEEDLE matches a >4 MiB resource.
- search: native grep silently skips files above NATIVE_GREP_MAX_FILE_BYTES (4 MiB), so the RE2 virtual path dropped matches for large virtual resources (history://, big artifacts). searchVirtualResources now falls back to a JS RegExp matcher for oversized content (the pre-RE2 behavior) while keeping native parity for normal sizes; buildVirtualMatches still rebuilds context/ranges.
- ssh write: a trailing-slash target (ssh://h/dir/) is now rejected before staging, so the mkdir -p parent-creation no longer leaves a directory behind on a refused write.
- search: the native virtual probe capped matched-line detection at INTERNAL_TOTAL_CAP before range filtering, so a ranged virtual selector (ssh://h/log:5000-5100) over a file with >2000 earlier matches returned nothing. The probe now uses the line-count bound for ranged resources so range filtering sees every hit.
- ssh write: writeRemoteFile staged into a temp beside the destination before creating parents, so writing a new nested path failed with 'No such file or directory'. It now mkdir -p's the parent before staging, matching local write, keeping the directory/special-file refusal checks.
searchVirtualResources matched with JS RegExp, so an ssh:// (or other virtual) search diverged from local search for RE2-valid but JS-invalid patterns (e.g. (?i)x, [[:digit:]]) — throwing 'Invalid regex' or returning different matches even when local grep had already validated the pattern in a mixed scope. It now detects matched line numbers with native grep (the same RE2 matcher local search uses) and rebuilds the existing forward-only, range-trimmed context windows via buildVirtualMatches, so virtual/remote and local search share one dialect. Removed the now-dead JS-regex helpers (probeRegexDialect, compileVirtualRegex, searchVirtualResource{Lines,Multiline}, findLineIndex).
search's generic glob-char guard saw the [ ] of an IPv6 authority (ssh://[::1]/etc/hosts) and threw 'Glob patterns are not supported' before the SSH handler could strip the brackets. The check now runs only on the path portion for ssh:// URLs, so IPv6 literals resolve while a glob in the remote path (ssh://host/p*) still rejects.
- reject explicit ssh:// port 0 before connecting (Codex P2)
- keep a path-less ssh://host:port authority port out of selector peeling
- restore ResolveContext on ProtocolHandler.complete (symmetry with resolve/write)
- clarify search/read selector-parity docs + add read-side regression
- `read ssh://host/dir` lists a remote directory one level deep; `ssh://host/` lists the remote root
- add statRemotePath + listRemoteDir; resolve reads first and classifies on error (directory -> one-level listing, dirs-first, dotfiles included)
- directory resources carry isDirectory + immutable and expose no sourcePath
- search refuses a virtual (no-sourcePath) directory resource instead of grepping the listing text
- writeRemoteFile refuses a directory destination and cleans up its temp on that path
- buildSshTarget rejects destinations beginning with "-" (SSH argument-injection / local RCE guard)
- gate ssh:// read/search/write at the exec approval tier; substring scan covers search's pre-expansion delimited paths and write's hashline-wrapped paths
- validate the entire materialized buffer as UTF-8 instead of only the first 8 KiB prefix
- write peels read selectors (raw/conflicts) so it targets the same file read does, and rejects line-range/malformed selectors instead of silently stripping them
- write to a uniquely named remote temp; document symlink-replacement on write as a v1 limit
- Added tree-sitter markdown support to resolve headings into full sections in `pi-ast`.
- Enabled block operations (`SWAP.BLK`, `DEL.BLK`, `INS.BLK.POST`) on markdown headings so they encompass the entire section, including nested deeper headings.
- Updated system prompt to guide agents in using structured markdown heading edits for plans.
- Fixed `plan-mode-guard` to correctly resolve local protocol options for subagents.
