The hint '(MOST COMMON for single-line edits)' misleads agents into
thinking pos-only replace is the default behavior. When agents want
to replace multiple lines but only specify pos without end, the tool
only replaces one line, causing duplicate code from retained lines.
- Canonicalize anchors in dedupe keys to handle whitespace variants
- Make lines field required in edit operations
- Only allow unanchored append/prepend to create missing files
- Reorder delete/rename validation to prevent edge cases
- Add allow_non_gpt_model and max_prompt_tokens to config schema
```
- Replace regex /^([A-Za-z_]+)#.../ with indexOf-based prefix check to catch
line-ref#VK and line.ref#VK style inputs that were previously giving generic errors
- Extract parseLineRefWithHint helper to eliminate duplicated try-catch in
validateLineRef and validateLineRefs
- Restore idempotency guard in appendWriteHashlineOutput using new output format
- Add tests for LINE42 extraction, line-ref hint, line.ref hint, and guard behavior

- Detect non-numeric prefixes (e.g., "LINE#HK", "POS#VK") and explain
that the prefix must be an actual line number, not literal text
- Add suggestLineForHash() that reverse-looks up a hash in file lines
to suggest the correct reference (e.g., Did you mean "1#HK"?)
- Unify error message format from "LINE#ID" to "{line_number}#{hash_id}"
matching the tool description convention
- Add 3 tests covering non-numeric prefix detection and hash suggestion
applySetLine, applyReplaceLines, applyInsertAfter, applyInsertBefore
were re-exported from both edit-operations.ts and index.ts but have no
external consumers — they are only used internally within the module.
Only applyHashlineEdits (the public API) remains exported.
Remove the old LINE:HEX (e.g. "42:ab") reference format support. All
refs now use LINE#ID format exclusively (e.g. "42#VK"). Also fixes
HASHLINE_OUTPUT_PATTERN to use | separator (was missed in PR #2079).
This function is no longer called from edit-operations.ts after the
op/pos/end/lines schema refactor in PR #2079. Remove the function
definition and its 3 dedicated test cases.
restoreIndentForPairedReplacement() and restoreLeadingIndent() unconditionally
restored original indentation when replacement had none, preventing intentional
indentation changes (e.g. removing a tab from '\t1절' to '1절'). Skip indent
restoration when trimmed content is identical, indicating a whitespace-only edit.
Change LINE#HASH:content format to LINE#HASH|content across the entire
codebase. The pipe separator is more visually distinct and avoids
conflicts with TypeScript colons in code content.
15 files updated: implementation, prompts, tests, and READMEs.
Unify internal hashline edit handling around replace/append/prepend to remove legacy operation shapes. This keeps normalization, ordering, deduplication, execution, and tests aligned with the new op/pos/end/lines contract.
Unify hashline_edit input with replace/append/prepend + pos/end/lines semantics so callers use a single stable shape. Add normalization coverage and refresh tool guidance/tests to reduce schema confusion and stale legacy payload usage.
Keep current field names but accept a pi-style flexible edit payload that is normalized to concrete operations at execution time.
Response now follows concise update/move status with diff metadata retained, removing full-file hashline echo to reduce model feedback loops.

Switch line hashing to significance-aware seeding so meaningful lines stay stable across reflows while punctuation-only lines still disambiguate by line index.
Also narrow prefix stripping to hashline/diff patterns that reduce accidental content corruption during edit normalization.

- Track matchedLen separately for stripped continuation token matches
- Map fuzzy index back to original string position via character-by-character
scan that skips operator chars, fixing positional correctness
- maybeExpandSingleLineMerge now uses stripTrailingContinuationTokens and
stripMergeOperatorChars as fallback matching strategies
- Add 'refs interpreted against last read' atomicity clause to tool description
- Add 'output tool calls only; no prose' rule to tool description
- Rewrite restoreOldWrappedLines to use oh-my-pi's span-scanning algorithm
- Add stripTrailingContinuationTokens and stripMergeOperatorChars helpers
- Fix detectLineEnding to use first-occurrence logic instead of any-match
- Fix applyAppend/applyPrepend to replace empty-line placeholder in empty files
- Enhance tool description with 7 critical rules, tag guidance, and anti-patterns
- runtime-fallback: guard session.error with sessionRetryInFlight to prevent
double-advance during active retry; expand session.stop abort to include
sessionAwaitingFallbackResult; remove premature pendingFallbackModel clearing
from auto-retry finally block
- hashline-edit: add HASHLINE_LEGACY_REF_PATTERN for backward-compatible
LINE:HEX dual-parse in parseLineRef and normalizeLineRef
- tmux-subagent: defer session on null queryWindowState; unconditionally
re-queue deferred session on spawn failure (not just close+spawn)
- ultrawork-db: wrap new Database(dbPath) in try/catch to handle corrupted DB
- event: add try/catch guards around model-fallback logic in message.updated,
session.status, and session.error handlers
- applyReplaceLines: use stripped array directly instead of restoreLeadingIndent
- applySetLine: keep restoreLeadingIndent (1:1 replacement needs indent preservation)
- Added test case for replace_lines preserving new line indentation
- All 3025 tests pass

Breaking Changes:
- Change hashline format from 'lineNum:hex|content' to 'lineNum#CID:content'
- Replace hex-based hashing (00-ff) with CID-based hashing (ZPMQVRWSNKTXJBYH nibbles)
- Simplify constants: HASH_DICT → NIBBLE_STR + HASHLINE_DICT
- Update patterns: HASHLINE_PATTERN → HASHLINE_REF_PATTERN + HASHLINE_OUTPUT_PATTERN
Benefits:
- More compact and memorable CID identifiers
- Better alignment with LSP line reference format (lineNum#ID)
- Improved error messages and diff metadata clarity
- Remove unused toHashlineContent from diff-enhancer hook
Updates:
- Refactor hash-computation for CID generation
- Update all diff-utils to use new format
- Update hook to use raw content instead of hashline format
- Update tests to match new expectations
🤖 Generated with assistance of [OhMyOpenCode](https://github.com/code-yeongyu/oh-my-opencode)
- Include line number in hash computation to ensure uniqueness
- Add explicit examples of WRONG vs CORRECT LINE:HASH format
- Clarify that hash must be hex characters (0-9, a-f only)
- Update tests to use dynamic hash computation
Align edit/write hashline handling with TUI expectations by preserving metadata through tool execution, keeping unified diff raw to avoid duplicated line numbers, and tightening read/write/edit outputs plus tests for reliable agent operation.
- P2: Change replace edit sorting from POSITIVE_INFINITY to NEGATIVE_INFINITY
so replace edits run LAST after line-based edits, preventing line number
shifts that would invalidate subsequent anchors
- P3: Update tool description from SHA-256 to xxHash32 to match actual
implementation in hash-computation.ts
