- 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
