Definitions and evidence cite the tag `registry-v1.1`. **User's decision (11 Nov 2026): the verifier version of `dail.verify.public_ingress` stays `"1"`**: registry v1.1 changes exactly what the work package lists and §10 is not among them; v1 and v2 evidence are already told apart by `invariant_version` (C-62). Question for the reviewer: should a later registry bump §10 when a predicate changes? | Decided (user, 11 Nov 2026) | | C-181 | P6d: implementation readings for registry v1.1 | (1) `core/domain/registry_v1_1.py` is a new module beside `registry_v1.py`, which keeps building the v1.0 definitions unchanged (they are what TerraPreserve v1.0's labels and the existing fixtures cite, and its tests read the v1.0 file). v1.1 takes INV-SEC-001/002 from v1.0, sets `version = 2`, cites `registry-v1.1` in `predicate.registry` and the description; INV-SEC-003 and INV-FUNC-001 are the v1.0 definitions object for object (same `definition_hash`, so a stored definition of the same id and version is not contradicted). (2) The public-ingress verifier reads `predicate.registry` of the definition: `registry-v1.0` evaluates the v1.0 clause, `registry-v1.1` the v1.1 clause, any other tag raises (VERIFIER_ERROR, fail closed). The direct function's default is v1.1 (the conservative one); baseline resource items use it. (3) C-146 (2) is kept: a rule whose direction is unresolved is `possible` for a family when it has any known source of that family (wider than v1.1). (4) The citation `registry-v1.0` that the verification engine and the impact work items wrote for every invariant now comes from the definition's `predicate.registry`. (5) The test pipeline (`tests/promotion_pipeline.py`) takes the definitions and the registry version as keywords; the default stays v1.0, so no passed test changes its inputs. **Authors' decision (11 Nov 2026): accepted as built after external review.** | Decided (authors, 11 Nov 2026) | | C-182 | P7a: the only real LLM provider, and experiment models (C-71) | **Advisor's decision (11 Nov 2026; C-71):** the only real provider in this repository is a local Ollama server.

Row P7b-2 is C-190. | Decided (authors, 12 Nov 2026) | +| C-188 | P7b: the meaning of an LLM patch (closes C-174 for LLM candidates) | **Authors' decision (12 Nov 2026):** An LLM patch is a set of complete Terraform `resource` blocks. For each address in `changed_addresses`: if the patch holds a block for it and the parent has it, the block replaces the parent's block (MODIFY); if the patch holds a block and the parent does not have it, the block is added (CREATE); if the patch holds no block for it, the parent's block is removed (DELETE). Everything else in the parent configuration is copied byte for byte. The candidate directory is built from the parent and the patch, so the patch and the candidate cannot disagree. C-174 stays a limit for FIXED_PATCH candidates only. | Decided (authors, 12 Nov 2026) | +| C-189 | P7b-1: application rules | Addresses are configuration addresses (`type.name`, no instance key, no `module.` prefix); an instance address or module address in `changed_addresses` is INVALID_OUTPUT. A replaced block keeps its file and position (the bytes of the parent block's source range are replaced); a deleted block's bytes are removed; created blocks are written, in `changed_addresses` order, to one new file `dail_llm_patch.tf` in the candidate directory. The parent directory is never written. The candidate is built in a fresh isolated directory (Doc 03 §4.5 step 3). | Proposed (P7b) | +| C-190 | P7b-2: scope (Doc 10 §15) | `AllowedChangeScope { resource_addresses, resource_types, attributes, operation_types }` is given by the caller (the controller), never derived by the LLM channel and never by the context builder. MODIFY and DELETE need the address in `resource_addresses`; CREATE needs the type in `resource_types` and a new address; every touched type must be in `resource_types` and in the supported model. Empty `attributes` means no attribute restriction; a non-empty list allows only those top-level arguments and nested block types to differ between parent and patch block. A breach is POLICY_VIOLATION (type outside the supported model: UNSUPPORTED). This replaces the parser's address-scope check; the parser keeps only the format checks, and its version becomes `dail-llm-parser-2`. | Proposed (P7b) | +| C-191 | P7b-3: operation check after identity | After the candidate is built and identity has run, every change type must be allowed by `operation_types`: CREATED→CREATE, MODIFIED→MODIFY, DELETED→DELETE, REPLACED→REPLACE, and an UNCERTAIN pair counts as REPLACE. A breach is POLICY_VIOLATION and the candidate is not evaluated (Doc 10 §14 "destructive operations outside the defined experiment scope", enforced with DAIL's own deterministic identity, not the model's claim). The default used in tests allows all four. | Proposed (P7b) | +| C-192 | P7b-4: failure classes for validation | HCL syntax error, a block for an address not in `changed_addresses`, two blocks for one address, DELETE of an address the parent does not have, a reference whose root is not declared in the candidate (resource, `var`, `local`, `data`) → INVALID_OUTPUT (retryable, Doc 10 §22 "optionally retry"). Forbidden constructs and credentials → POLICY_VIOLATION (not retried). Unsupported types or constructs → UNSUPPORTED (not retried). Each attempt's validation result is in its response record with the validator version `dail-patch-validator-1`. | Proposed (P7b) | +| C-193 | P7b-5: prompt version | The prompt must now describe the patch format of C-188, so it gets a new version `dail-repair-prompt-2` with a new pinned hash; `dail-repair-prompt-1` stays reproducible. | Proposed (P7b) | +| C-194 | P7b: `llm.api_key_ref` stays in the schema | The work package asked to remove the unused key and its pinned-key test entry. It is the only `SECRET_REF` key of the schema: about ten tests in `tests/unit/test_config.py` and `tests/unit/test_health.py` exercise the `env:NAME` secret machinery and the C-25 reserved-prefix rule through it, so removing it would delete or rewrite them (CLAUDE.md: tests only get stronger). **User's decision (12 Nov 2026): keep the key, record why.** No provider reads it (C-71: no keys). | Decided (user, 12 Nov 2026) | From dca71af21685ff818c9c2dc586879d9d382e4a17 Mon Sep 17 00:00:00 2001 From: Ayushxsingh100 Date: Thu, 12 Nov 2026 10:38:30 +0530 Subject: [PATCH 2/4] =?UTF-8?q?P7b=20steps=202-3:=20patch=20validator=20an?= =?UTF-8?q?d=20candidate=20build;=20LLMEvaluationRequest;=20scope=20and=20?= =?UTF-8?q?operation=20check;=20parser=202,=20prompt=202=20(Doc=2010=20?= =?UTF-8?q?=C2=A712-=C2=A715,=20=C2=A722,=20=C2=A727,=20=C2=A735,=20=C2=A7?= =?UTF-8?q?38-=C2=A740;=20Doc=2003=20=C2=A74.5-=C2=A74.7;=20C-188=20to=20C?= =?UTF-8?q?-193)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit llm/validation/patch.py runs the §13 checks in order (syntax, top-level blocks, forbidden constructs, boundaries, scope, credentials, invented ids, build in a fresh directory, references, normalize, identity with the operation check). The parent directory is never written. AllowedChangeScope and operation_breaches live in core.domain.change_scope. LLMEvaluationRequest binds a built directory to its patch by tree hash. The parser keeps only the format checks (dail-llm-parser-2). The prompt is dail-repair-prompt-2; v1 stays reproducible. P7a tests whose expectations C-190 and C-193 supersede are updated with notes: the scope check moved from the parser to the validator, a stub validator keeps all eight failure classes in the mapping test, the prompt version is now 2, and the context takes the caller's scope.

(2) **Attributes (C-190).** A non-empty `attributes` restricts MODIFY only: CREATE has no parent block to compare with and DELETE has no patch block. Arguments and nested blocks are compared by name, each with its whitespace-normalized source texts. (3) **Lifecycle.** Compared as the list of whitespace-normalized `lifecycle` blocks of the resource; a CREATE has no parent, so any `lifecycle` in it is POLICY_VIOLATION. (4) **Credentials (§14).** A secret-named argument (the `Redactor` key rule) at any depth, identified by its path of block types and name, must have the whitespace-normalized text of the parent's argument at that path or be a `var.` reference. (5) **Invented ids (§14).** The id pattern is matched inside every string literal and template text, bounded by non-alphanumeric characters; an `arn:aws:` string counts as invented when it does not occur in the parent text. (6) **References.** The roots `count`, `each`, `self`, `path`, `terraform` and for-expression iterators are not configuration names; P3's loader would also refuse an undeclared reference later, so check 9 is a first line, and the tests require that check 9 itself reports. (7) **Fail closed.** MODIFY or DELETE of a block that lives in a `.tf.json` file is UNSUPPORTED; a parent that already has `dail_llm_patch.tf` is UNSUPPORTED for CREATE; a parser limit (C-93) is UNSUPPORTED; a built candidate whose normalization is UNSUPPORTED is UNSUPPORTED and no candidate exists (Doc 03 §4.7 lets a pipeline continue only where it permits; P7b does not). (8) **Exact parent.** The validator refuses, at construction, a parent directory whose normalized resource set does not have the trusted state's `resource_set_hash` (Doc 03 §4.5 step 1). (9) **Operation check (C-191).** It runs inside the validator with DAIL's own identity engine against the trusted state's resources; the orchestrator runs identity again on the same inputs, so the result is the same. (10) **Entry path.** `LLMEvaluationRequest` is a subclass of `EvaluationRequest` (one evaluation path) that accepts only an LLM `Patch`, carries `built_tree_hash`, and recomputes the directory's tree hash; a fixed-patch request still refuses an LLM patch. (11) **Context and validator agree.** `Generator` refuses a context whose parent state or change scope is not the validator's. (12) **Builds.** A refused build is removed at once; a successful one stays under the caller's `work_root`, which the caller owns. | Proposed (P7b) | diff --git a/docs/PHASE_GATES.md b/docs/PHASE_GATES.md index f7d3487..54c10b0 100644 --- a/docs/PHASE_GATES.md +++ b/docs/PHASE_GATES.md @@ -333,7 +333,82 @@ loopback fake server, not the real one; the wiring check ran once on one machine Carry-forward: C-183 to C-187 Proposed; ADR-006 Proposed. ``` -## P7b–P10 — NOT STARTED +## P7b — From LLM patch to Candidate State (pending external review) + +```text +P7b mini-gate: NOT DECIDED.
