Upstream main 52b8fb156 changed normalizeGeneratedTitle to reconcile a generated title's casing against the user's message instead of forcing Title Case, and updated the tiny-text unit tests but not the title-generator/role-thinking integration suites. The rebase surfaced their stale Title-Case expectations as CI failures. Update the 6 expectations to the reconciled output; no production code change.
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
- ssh handler complete() suggests the configured hosts; bare `read ssh://` resolves to an immutable host index (markdown links per host)
- thread a minimal cwd through the completion pipeline (provider basePath -> getInternalUrlSuggestions -> router.complete -> handler.complete) so project-scoped ssh.json hosts resolve like the cwd-aware bare-read path
- scoped to configured SSH-capability hosts; opaque ~/.ssh/config aliases stay usable at ssh://alias/path but are not enumerated
- local handler complete() signature updated to match (behavior preserved; the router never threaded context to it)
- `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
- Updated `normalizeGeneratedTitle` to reconcile model-generated titles against the user's input instead of forcing title-case.
- Added logic to restore distinctive proper-noun casing (e.g., `TinyVMM`) and flatten model-generated camelCase artifacts (e.g., `dAemon`) that do not appear in the user's message.
- Ensured model-cased proper nouns that are not in the source message (e.g., `GitHub`) are preserved.
Fixed a non-deterministic gc-cli archive test: archive-me and keep-recent
shared ageDays:90, so their mtimes tied within a millisecond on fast CI and
the retainNewestGlobal:1 'keep newest' pick fell back to readdir order,
archiving the wrong session. Give keep-recent ageDays:60 (still cold-eligible,
unambiguously newer).
- Added instructions for writing sections as cohesive multi-line blocks when performing edit operations.
- Clarified that block operations require multi-line sections to avoid falling back to standard editing behavior.
- 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.
The createAgentSession default-role resolution ran before extension
factories registered their providers, so a default role pointing at an
extension-provided model (e.g. an openai-compat plugin's
posthog/claude-opus-4-8) returned undefined there. On a fresh launch
(no -c/--resume) the post-extension fallback went straight to
pickDefaultAvailableModel and replaced the user's configured default
with the first bundled provider default that had auth — commonly
openai/gpt-5.5 when OPENAI_API_KEY was set.
The fallback now retries resolveModelRoleValue against the
post-extension allowed-model set before pickDefaultAvailableModel, and
re-applies the role's explicit thinking selector / model host
preconnect.
Fixes#3569
Detected whether the OMP host already owns an inheritable Windows console before resolving stdio MCP spawn flags.
Skipped CREATE_NO_WINDOW for console-attached MCP wrapper chains so cmd.exe and PowerShell grandchildren reuse the existing terminal instead of allocating visible conhost windows.
Fixes#3567
- Removed multiple test files and cases that relied on brittle source string matching for validation.
- Updated project architecture documentation to explicitly prohibit source-grep style testing patterns.
- Eliminated legacy reproduction tests for issues that reached project maturity.
- Fixed stale `preserveData.snapcompact` frames leaking into context-full compaction after switching from `snapcompact` to `context-full` strategy, which inflated context usage and made sessions appear to compact prematurely.
- Added secret redaction for migrated snapcompact archive plaintext (`text`/`textHead`/`textTail`) during the snapcompact->context-full transition, while preserving opaque provider-replay state byte-identical.
- Added `archiveSourceText()` and `stripPreservedArchive()` utilities to snapcompact module for archive extraction and cleanup.
- Added a fallback from `hashline` to `replace` mode for Kimi-family models to resolve compatibility issues.
- Introduced `PI_STRICT_EDIT_MODE` environment variable to bypass automatic model-specific edit-mode fallbacks.
- Updated `getEditVariantForModel` to perform case-insensitive matching for model variant configurations.
- Added comprehensive unit tests for edit mode resolution and settings configuration.
Hidden slider means the operator made no choice; a singleton cycle built around the active plan model must not be pinned as executionModel, otherwise approval re-applies the plan model after #exitPlanMode restored the pre-plan one.
Added regression coverage for the plan-only role configuration.

Same-model role with an explicit thinking suffix that differs from the pre-plan thinking now passes through applyRoleModel instead of being treated as an implicit match.
Added regression coverage for the sonnet:off vs pre-plan thinking-high case.

Compared the selected approval tier against the model restored after plan mode instead of the active plan-mode tier.
Added regression coverage for keeping the active planning model selected on approval.
