v0.4.3

Changed

• README: removed the "ROSE reborn" line from the research-lineage section.

v0.4.2

Fixed

• README demo images use absolute raw.githubusercontent URLs again: the README
  doubles as the nuget.org package README, where relative image paths do not
  resolve — 0.4.1's package page shows them broken.

v0.4.1

Changed

• CLI confidence values print with three decimals (0.796, not 0.80): two-decimal
  rounding could display a value at a floor it does not actually reach, making
  stats rule counts and check output look contradictory. Thresholds and the
  README's worked examples updated to match.
• README: real CLI demo screenshots (stats, check with the decision guide,
  pre-commit hook), fixed section anchor links, quick-start reshuffle.

v0.4.0

Added

• unwritten ignore <trigger> <hole> --for <n> — bounded mute for a
  persistently false rule. Expires after the trigger has changed n more
  times (default 30; those are the commits that erode or re-confirm the rule),
  shows as suppressed with the remaining budget rather than disappearing,
  is overridden by check --strict, and lives in machine-managed
  .unwritten/ignores.json. --list / --remove manage entries; expired
  entries are pruned automatically. Deliberately CLI-only — no MCP tool, so
  agents cannot mute their own warnings. Permanent ignores do not exist by
  design: unbounded mutes go stale and eventually hide real omissions.

Changed

• Refreshed project artwork (package icon, registry icons, social card).

v0.3.0

Added

• baseRef support (MCP check_holes parameter, CLI --base <rev>): measure
  the edit against a chosen revision instead of HEAD. Essential for commit-as-you-go
  agent sessions — pass the pre-work SHA and committed edits are still seen.
• Changed-file auto-detection: omit files in check_holes (or run
  unwritten check with no arguments) to check every uncommitted change —
  staged, unstaged, and untracked (or everything since baseRef).
• Per-file data status: check_holes returns checkedFiles with
  totalChanges/canTriggerRules per input, plus notes when a file has no or
  too little history — an empty result now says "no data" instead of looking
  like "all good". The CLI prints the same as note: lines.
• unwritten install-hook: one command installs a git pre-commit hook
  (--git), a Claude Code Stop hook (--claude-code), or both — deterministic
  invocation instead of hoping the agent remembers the tool. The Stop hook runs
  unwritten hook stop, which feeds failing holes back to the agent (exit 2)
  and always fails open.
• Automatic reindex on training-config change: editing training settings in
  .unwritten/config.json (minSupport, maxTransactionSize, member settings
  including memberHistoryWindow, …) now triggers a rebuild on the next query;
  floor changes apply immediately, including in the MCP server. Manual
  reindex remains for history rewrites. Existing member indexes are rebuilt
  once (the history window is now part of the persisted training fingerprint).
• .unwritten/ now writes its own .gitignore — no root .gitignore edit needed.
• First index build creates .unwritten/config.json as a fully commented
  template: every setting is discoverable in place, and nothing is pinned, so
  future default improvements still apply.
• Config validation with clear errors (invalid JSON or out-of-range values in
  .unwritten/config.json no longer crash with a stack trace).
• CLI: --version, --help/-h (also for check), friendly error for
  repositories without commits.

Fixed

• False "cosmetic edit" suppression after committing: when the working tree
  matched HEAD (agent committed, then checked), every C#-triggered hole was
  suppressed as a whitespace/comment-only edit. Identical content is now treated
  as "no visible edit" and fails open.
• Any path inside the repository now works as repoPath: it is resolved to the
  repo root (git rev-parse --show-toplevel), so monorepo subdirectory paths no
  longer silently produce zero matches.
• Path normalization: leading ./ segments are stripped, and absolute paths in
  a sibling directory sharing a name prefix (repo vs repo2) are no longer
  mis-relativized; repo-root matching is case-insensitive on Windows only.
• A corrupt .unwritten/index.json triggers a silent rebuild instead of
  crashing every subsequent command.
• git cat-file --batch stdin is now UTF-8, so non-ASCII file paths no longer
  silently drop out of member-level training on Windows.
• The "no visible edit" guard now compares content with normalized line
  endings: with core.autocrlf the working tree (CRLF) never matched the blob
  (LF) byte-for-byte, which re-enabled the cosmetic-suppression false positive
  on Windows.
• Index saves use a unique temp file name — concurrent saves (MCP server +
  pre-commit hook) can no longer collide.

Changed

• MCP responses are compact JSON (fewer tokens per call).
• check_holes clamps an explicit minConfidence below 0.3 (with a note) —
  validated as ~90% noise.

v0.2.1

Added

• README badges: NuGet version, downloads, license (same style as McpOrchestrator).
• Project icon (img/): embedded as the NuGet package icon and listed in the
  MCP Registry manifest (icons in server.json).

v0.2.0

Changed

• Project renamed from ConventionSense to Unwritten. New NuGet package ID
  Unwritten, tool command unwritten, MCP server name
  io.github.Byggarepop/unwritten, index directory .unwritten/, and repository
  URL https://github.com/Byggarepop/Unwritten. Versions ≤ 0.1.2 were published
  as ConventionSense; earlier changelog entries below refer to the old name.

v0.1.2

Changed

• README (also shown on nuget.org): plain-language "what it adds" and
  thresholds sections, two-step quick start, per-client MCP setup
  (Claude Code, VS Code, Visual Studio 2026), a ready-to-copy capability
  description for MCP gateways like McpOrchestrator, and all examples
  using dotnet tool execute — no install step. Docs only; no code changes.

v0.1.1

Fixed

• MCP Registry listing: server.json description shortened to the registry's
  100-character limit (the v0.1.0 registry publish was rejected with a 422).

v0.1.0

Added

• Change-coupling indexer over git history: non-merge commits touching ≤ 30 files,
  Wilson lower bound scoring, alert floor 0.6, minimum support 10, incremental
  updates keyed by HEAD (.conventionsense/index.json).
• MCP server (conventionsense mcp) with five tools: check_holes,
  expected_companions, explain_rule, stats, reindex — every alert carries
  counts, confidence, and example commits as evidence.
• Pre-commit CLI: conventionsense check --staged (exit 1 at ≥ 0.7, configurable
  via --fail-at), plus stats and reindex subcommands.
• Per-repo configuration in .conventionsense/config.json; CLI flags override
  config, config overrides defaults.
• Content-aware exception layer for JSON triggers: learns which top-level keys
  ("facets") predict each rule and suppresses alerts for non-predictive edits
  (e.g. pure version bumps). Suppressed holes are excluded from the exit code;
  --strict re-includes them. Fail-open everywhere.
• Opt-in C# member-level detection ("memberLevel": true): members as entities
  (Namespace.Type.Member/arity, survives file renames), Roslyn syntax-only
  diffing, member holes in check_holes and the CLI, cosmetic-edit suppression
  (whitespace/comment-only C# edits), 5,000-commit training window.
• Packaged as a dotnet tool (ConventionSense, command conventionsense).

Notes

• Renamed from the working title "Lacuna"; the original spec document
  (lacuna-claude-code-prompt.md) keeps the old name as a historical record.
