It is **default-off** +and designed to support agent-driven refactoring and feature decommissioning workflows. + +## Overview + +When autonomous agents perform refactoring or feature replacement tasks, they +frequently exhibit an "entropy growth" anti-pattern: layering yet another wrapper +or fallback branch without safely deleting superseded implementations. Over +long-horizon tasks, this results in accumulated ghost code, redundant complexity, +and bloated execution contexts. + +The Anti-Entropy capability addresses this through: + +1. **AST-Based Delete-First Enforcement (`verify_delete_first`)**: + Uses Python's syntax tree parser to verify that declared retirement targets + (functions and classes) are genuinely removed from the codebase rather than + merely bypassed or wrapped. +2. **Zombie Symbol Prevention**: + Detects if a symbol marked for retirement is reintroduced as a new definition + in newly added code lines. +3. **Target Paths Verification**: + Ensures that declared legacy file paths slated for deletion are completely + removed in the unified diff (`/dev/null`). +4. **Ghost Code Auditing (`audit_ghost_code`)**: + Identifies commented-out code blocks left behind, surfacing them as advisory + quality findings without blocking legitimate documentation or explanatory comments. +5. **Durable Receipt Generation (`AntiEntropyReceipt`)**: + Runs deterministic hygiene oracles against the exact git diff and produces + an immutable receipt recording verified retired symbols and findings. + +## Attribution & Acknowledgments + +This capability adopts and operationalizes the core engineering principles of +**delete-first retirement**, **ghost code prevention**, and **minimality verification** +inspired by the **Aegis** engineering methodology. + +## Usage + +Inspect the capability and its registered protocols: + +```bash +loopx capability show anti-entropy-governance --format json +``` + +Verify diff

The core question was: +- Should test/benchmark scenarios overlay a full real-world development task? +- How should the anti-entropy capability be injected into commands to measure the delta between having vs. not having anti-entropy governance? +- What task scenario is most appropriate to evaluate this without compromising LoopX core stability? + +--- + +## 2. Decision Points & Trade-Off Analysis + +### Decision 1: Loading Mechanism & Interception Timing +- **Considered Alternatives**: + - *Option 1*: Pure prompt guidance (soft constraint). Zero tooling overhead, but models consistently regress under multi-file pressure. + - *Option 2*: Post-hoc terminal gate only. Verifies diff at submission; fails late when the agent has already exhausted budget, leading to blind rollback loops. + - *Option 3 (Selected)*: **Two-Tier Closed Loop (Execution Tool + Submission Gate)**. + - Exposes `anti_entropy_inspect` as an advisory tool during execution so the agent can self-audit diff cleanliness. + - Chains `loopx anti-entropy verify` into the delivery evaluation command, failing the run if `AntiEntropyReceipt.verdict != "passed"`. +- **Trade-off**: Increases tool-call rounds and slight token overhead per run, in exchange for deterministic first-pass cleanliness and eliminating expensive blind rollbacks. + +--- + +### Decision 2: Zero-Intrusion Packaging & Retirement Basis Injection +- **Considered Alternatives**: + - *Option 1*: Hardwire anti-entropy check into `loopx/control_plane/turn_driver/`. Causes direct intrusion into generic mainline scheduling, violating domain-neutrality. + - *Option 2*: Dynamic runtime AST inference without declaration. Prone to false positives when agents refactor internal helper functions. + - *Option 3 (Selected)*: **Declarative Sidecar / Task-Envelope Hook Pattern**. + - The task specification explicitly provides an `anti_entropy_basis` (target symbols and target paths to retire). + - The benchmark/test runner wraps the task externally: conditionally injects the inspect tool into the agent envelope and appends the verify CLI command to the test command. + - `loopx/control_plane/` remains completely unmodified (0-line diff). +- **Trade-off**: Requires test cases to declare their target retirement list in advance, rather than inferring intent magically. + +--- + +### Decision 3: Evaluation Benchmark Scenario (Testbed Task) Selection +- **Considered Alternatives**: + - *Option 1*: In-repo dogfooding on live LoopX modules. High risk of breaking the developer active branch during failed baseline runs; violates mainline safety. + - *Option 2*: External SWE-bench Docker benchmark. Requires heavyweight containers and environment setups; feedback loop too slow for local iterative testing. + - *Option 3 (Selected)*: **Self-Contained Realistic Engineering Playground in `examples/anti_entropy/`**. + - A multi-module Python service (protocol parser + streaming receiver + client caller + unit test suite). + - Real task: Migrate all callers from `LegacyProtocolParser` to `StreamMessageParser` and physically delete `legacy_parser.py`. + - Automated comparator evaluates Arm 1 (Baseline), Arm 2 (Prompt Only), and Arm 3 (Two-Tier Anti-Entropy). +- **Trade-off**: Tests on a standalone engineering playground rather than mutating production LoopX code directly. + +--- + +## 3. First-Principles Minimality Justification (Aegis Integration) + +1. **Change Necessity**: Reuses the existing `loopx/capabilities/anti_entropy/` AST engine without creating redundant verification abstractions. +2. **Fallback Ceiling**: Refuses to add fallback adapters; enforces physical deletion of deprecated symbols (`/dev/null` diff + AST symbol absence). +3. **Delete-First & Anti-Entropy**: The evaluation suite directly measures net negative lines of code, absence of zombie wrappers, and 0 ghost code blocks. +4. **Mainline Purity**: All new harness scripts live in `examples/anti_entropy/` and `docs/decisions/`.

bind source evidence and wire task-scoped feedback loop Address PR #7545 review: require explicit workspace binding so symbol retirement is certified only against complete post-change sources (AE004 otherwise), parse bound sources with the AST instead of merging line signatures and free-text matches, exclude documentation files from symbol evidence, and record receipt provenance (basis_hash, source_root, source_evidence). Add loopx anti-entropy inspect as the in-flight progress-fact entry with the anti_entropy_inspect tool descriptor and turn-context projection; delivery acceptance stays owned by change-quality. Rewrite compare_arms.py as an honest isolated sandbox demonstration and fix Python 3.11 f-string syntax and ruff findings.

[PATCH 04/21] fix(anti-entropy): compose task-scoped feedback loop and harden source oracles Address the PR #7545 review round: compose anti_entropy_context_registration into the shared attach_turn_context owner with four lifecycle states (disabled zero-injection, enabled-not-applicable readback, active guidance, recovery remediation) so the capability gains a real production consumer while staying default-off and task-scoped. Rewrite TS/JS reference extraction to catch cross-file references after stripping comments and strings, and make workspace scan truncation (oversized files, file-count limits, read failures) a blocking AE004 that prevents retirement certification. Align the advertised delivery route with the real change-quality flow (prepare -> record --result-json --execute -> verify) and prove it end-to-end with a real CLI run plus a receipt-invalidation counter-example. Consolidate verify/inspect input reading into shared helpers.

A retirement declaration opts a task in; the post-change workspace is the Goal repository from the registry, never the process CWD. Disabled turns declare no readback slot, so no empty guidance field is injected into Host input. - The TS/JS lexer preserves statically named computed member accesses (api['old_api']) as executable references while array literals, plain strings and comments remain non-references. - verify fails closed: a missing basis or an empty target set is an input error (exit 2), never a passing verification; catalog entry_command / next_real_step now show the complete, certifying command and the README documents the actual activation and tool-delivery boundary. Validation: 67 focused tests (including two tests that build the real TS-owned Turn envelope from the canonical decision fixture and assert the composed Host input), full tests/capabilities suite, ruff, smoke and comparator pass.

The captured Host stdin contains the delete-first guidance, the anti_entropy_inspect route, and the Turn request with anti_entropy_context and its inspect_tool descriptor, while effects.host_invoked=true proves the Host was actually invoked. Document the routing caveat found by this run: a Todo's required_capabilities entry only opts in when the Goal already declares the capability available; otherwise routing stops the Turn before the hook, so the explicit task declaration is the primary opt-in.

Authorization now requires the reserved retirement_basis/anti_entropy_basis namespace; generic containers and the anti_entropy wrapper are carriers only. Intent is bound to the explicitly selected Todo id, so a stale recommended_action or unselected sibling cannot activate the current task. Goal-level availability and nested metadata/params enable flags no longer activate; the turn-context hook stays composed in the shared attach_turn_context owner on both production paths. Adds composer negative matrices, same-Goal/later-Todo native Host stdin coverage, heartbeat routing, and the R9 exact counterexample.

One shared JS/TS escape decoder now serves both layers (unicode, brace unicode, hex, legacy octal, identity escapes, line continuations). Decoded identifier members and bare identifier escapes become references; malformed executable escapes set scan_incomplete and produce blocking AE004; ordinary strings, template text, URLs and array literals stay non-references. Scan budgets are unchanged. Adds parameterized escape-form matrices, malformed-escape AE004 cases, a harmless/migrated control, and a real CLI exit-code regression.

Direct-caller payloads with multiple id-less records should provide `todo_id`. - A malformed explicit `retirement_basis` value is inert and fails closed; it cannot activate partial policy and may shadow a later valid declaration in the same carrier. - Escaped definition names and escapes outside value-position member/identifier references are outside the reference model. +- The hand-rolled lexer is not a complete JavaScript/TypeScript parser; closing arbitrary expression syntax requires a real parser and remains a bounded follow-up. diff --git a/loopx/capabilities/anti_entropy/oracles.py b/loopx/capabilities/anti_entropy/oracles.py index 9d0867df69..57d067f3e1 100644 --- a/loopx/capabilities/anti_entropy/oracles.py +++ b/loopx/capabilities/anti_entropy/oracles.py @@ -543,91 +543,379 @@ class _ComputedMember: name: str next_index: int resolved: bool + newlines: int = 0 +@dataclass(frozen=True, slots=True) +class _StaticKey: + """A statically evaluated computed-member key expression.""" + + value: str + next_index: int + resolved: bool + + +_JS_EXTRA_WHITESPACE = "\u00a0\u2028\u2029\ufeff" +_TS_ASSERTION_KEYWORDS = ("as", "satisfies") +_TS_IDENTIFIER_AT_RE = re.compile(r"[A-Za-z_$][A-Za-z0-9_$]*") + + +def _is_js_whitespace(char: str) -> bool: + return char.isspace() or char in _JS_EXTRA_WHITESPACE + + +def _skip_js_trivia(text: str, index: int) -> tuple[int, bool]: + """Skip JS whitespace and comments between tokens. + + Returns ``(index, True)`` on success and ``(index, False)`` for an unclosed + block comment; callers fail closed in that case. + """ + length = len(text) + while index < length: + char = text[index] + if _is_js_whitespace(char): + index += 1 + continue + if text.startswith("//", index): + cursor = index + 2 + while cursor < length and text[cursor] not in "\r\n\u2028\u2029": + cursor += 1 + index = cursor + continue + if text.startswith("/*", index): + close = text.find("*/", index + 2) + if close == -1: + return index, False + index = close + 2 + continue + break + return index, True + -def _previous_identifier_word(out: list[str]) -> str: - """Return the identifier word immediately before the current position.""" - chars: list[str] = [] - seen = False +def _previous_receiver_char(out: list[str]) -> str: + """Return the code character before the member bracket, skipping ``!`` suffix.""" for position in range(len(out) - 1, -1, -1): for char in reversed(out[position]): - if char.isspace(): - if seen: - return "".join(reversed(chars)) + if char.isspace() or char == "!": continue - if char.isalnum() or char in "_$": - chars.append(char) - seen = True - continue - return "".join(reversed(chars)) - return "".join(reversed(chars)) + return char + return "" -def _previous_code_char(out: list[str]) -> str: - for position in range(len(out) - 1, -1, -1): - stripped = out[position].rstrip() - if stripped: - return stripped[-1] - return "" +def _previous_receiver_word_info(out: list[str]) -> tuple[str, str]: + """Return the identifier before the member bracket and its prefix text.""" + code = "".join(out) + end = len(code) + while end and (code[end - 1].isspace() or code[end - 1] == "!"): + end -= 1 + start = end + while start and (code[start - 1].isalnum() or code[start - 1] in "_$"): + start -= 1 + return code[start:end], code[:start] -def _static_computed_member( - text: str, start: int, out: list[str] -) -> _ComputedMember | None: - """Preserve a statically named computed member access (api[name]). +_TS_CONTEXTUAL_MEMBER_WORDS = frozenset({"of"}) - Only a member name in a value position is preserved.

let-bound string keys and escaped computed keys now reject; - detect static string names in import/export clauses as executable references; - classify export-default object literals as non-references; - fix Python NFKC target/source mapping direction so a declared variant target matches the ASCII AST identity. Adds regression forms for all four cases.

Class/type-only property positions can therefore be conservative false rejects. - Reference extraction is token-kind conservative: identifier object-literal keys, regex-literal text, type-only positions, JSX text and same-named properties on unrelated receivers can be reported as references (false reject).
