    name: Fix all gate blockers from meta.review.meta-review-gate
    status: done
    description: 'Fix ALL blockers found by `meta.review.meta-review-gate`.


      ## Blockers to Fix (ALL of these, not just the first)


      ### B1: core.validate interface mismatch with `ARCHITECTURE.md`

      Locations: `core_validate` planning steps and related contract/test/implement
      expectations

      Remediation: align public names/signature to `ValidationIssue` / `ValidationReport`
      / `validate_spec`, or update the authoritative docs so one canonical source
      remains.

      Grep hint: `core_validate.core-validate-contract`

      IMPORTANT: search sibling `core_validate` execution steps (`tests`, `implement`,
      `verify`, `freeze`, `gate`) and any meta review evidence that repeats the old
      names/signature.


      ### B2: core.assemble contract shape/document conflict

      Locations: `core_assemble` planning steps and `meta.review` evidence

      Remediation: resolve `ARCHITECTURE.md` vs `INTERFACES.md` conflict on `AssemblyInput`
      by-name vs by-value and return type `PersonaSpec` vs `dict`; make one canonical
      contract source and align all dependent steps.

      Grep hint: `core_assemble.core-assemble-contract`

      IMPORTANT: search sibling `core_assemble` execution steps and final review evidence
      for repeated contract-shape assumptions.


      ### B3: shell.components component type ownership ambiguity

      Locations: `shell_components` planning steps

      Remediation: decide whether component types live in `core.spec` or `core.assemble`,
      then align dependencies, step text, and contract/test/implementation sequencing
      accordingly.

      Grep hint: `shell_components.shell-components-contract`

      IMPORTANT: search sibling `shell_components` steps plus upstream `core_spec`
      / `core_assemble` plan text for duplicated or conflicting ownership statements.


      ### B4: shell.python_api missing `app_facade` execution dependency

      Locations: phase `shell_python_api` depends_on / execution sequencing

      Remediation: add the missing `app_facade` dependency anywhere execution can
      otherwise start too early.

      Grep hint: `phase shell_python_api`

      IMPORTANT: search all `shell_python_api` steps for first-step and cross-phase
      dependency omissions, not just one line.


      ### B5: shell.cli missing `app_facade` execution dependency

      Locations: phase `shell_cli` depends_on / execution sequencing

      Remediation: add the missing `app_facade` dependency anywhere execution can
      otherwise start too early.

      Grep hint: `phase shell_cli`

      IMPORTANT: search all `shell_cli` steps for first-step and cross-phase dependency
      omissions, not just one line.


      ### B6: final cross-module review remains rework until B1-B5 resolved

      Locations: `meta.review.final`

      Remediation: rerun the final cross-module review after the blocker fixes land,
      and ensure the updated review evidence explicitly covers B1-B5 closure.

      Grep hint: `meta.review.final`

      IMPORTANT: search adjacent `meta.review` steps for stale review conclusions
      that would bypass the rerun.


      ## Completion Criteria

      - Fix ALL of these, not just the first

      - Perform systemic sibling searches for every blocker family

      - Keep plan executable and dependency-safe

      - Preserve independent review by routing verification back to `gate-reviewer`

      corrected sequencing'

      ### B1-family residual: stale `validate.py` required-fields contract text

      Locations: `src/larva/core/validate.py` around lines ~70 and ~83

      Remediation: update docstring/comment text to the canonical PersonaSpec field
      expectations, remove stale `spec_id` mentions, and align any `required fields`
      wording with the authoritative PersonaSpec/docs contract.

      Grep hint: search `spec_id` and `required fields` in `src/larva/core/validate.py`

      IMPORTANT: search sibling occurrences in this blocker family beyond the listed
      lines and fix ALL stale/conflicting mentions, not just the first match.


      ## Completion Criteria

      - ALL stale B1-family occurrences in `src/larva/core/validate.py` are corrected

      - `spec_id` is removed from this stale-conflict family where it contradicts
      the canonical contract

      - sibling search evidence is provided for the blocker family

      - scope remains limited to residual B1-family contract-text cleanup and does
      not reopen unrelated blockers

      so it loads documented component files into typed in-memory objects without
      widening module scope.


      step_type: implementation


      Scope:

      - implement the filesystem-backed `ComponentStore` adapter and typed shell errors
      using `Result[T, E]`

      - read prompt components from markdown files and return raw prompt text exactly
      as stored

      - parse toolset, constraint, and model YAML files into the corresponding `larva.core.spec`
      component objects

      - implement `list_components()` over the documented component directories and
      return a stable directory-keyed inventory for downstream `component list/show`
      transports to consume

      - constrain changes to `src/larva/shell/components.py` and `tests/shell/test_components.py`
      only


      Known risks:

      - boundary drift: do not add assembly rules, registry mutation, facade orchestration,
      or CLI/MCP formatting here

      - path semantics: the adapter must honor the documented `~/.larva/components/`
      layout and keep directory-to-type mapping exact

      - shell error drift: external read/parse failures must remain typed shell errors
      carried in `Result`, not transport-shaped JSON payloads

      - shared-registry conflict: do not modify `src/larva/__init__.py` or other shared
      export files


      State semantics:

      - prompt content is preserved exactly as file content

      - YAML-backed component objects preserve the documented field sets for their
      respective component type

      - backward-compatible behavior is limited to the documented component-store
      layout and shell `Result[T, E]` boundary


      Out of scope:

      - variable injection or component assembly

      - registry read/write behavior

      - CLI or MCP command implementation

      - facade-level orchestration across multiple modules'
    verification: '- Main path: targeted tests for prompt/toolset/constraint/model

      Independence Level: L1


      Test for:

      - Happy path: prompt, toolset, constraint, and model components load from the
      documented directory/file-format layout into the expected in-memory objects

      - Edge cases: `list_components()` stays stable when some component type directories
      are empty; prompt content is preserved exactly; YAML-backed loads reject cross-type
      path mixups

      - Error scenarios: missing components return typed shell errors through `Result`;
      shell code does not emit transport-shaped JSON errors; no assembly or registry
      behavior leaks into the module


      Document ALL findings. A verification step that discovers issues is a success.

      ## Blockers to Fix (ALL of these, not just the first)


      ### B1: Cross-type path mixup accepted by production loader

      Locations: `src/larva/shell/components.py`

      Remediation: enforce strict component name/path validation in production `FilesystemComponentStore`/loader
      entrypoints; reject `..` traversal, cross-type escapes, and model-to-constraints
      path mixups with typed shell `ComponentStoreError` results only.

      Grep hint: `load_model|_read_yaml|resolve|\..\/constraints|ComponentStoreError`

      IMPORTANT: search for sibling path resolution and loader call paths beyond the
      reported reproduction so no alternate escape path remains.


      ### B2: Target module coverage is CRITICAL (29%)

      Locations: `src/larva/shell/components.py`, `tests/shell/test_components.py`

      Remediation: add production-targeted integration tests using real temp fixtures
      that exercise load/list/error paths in the production module rather than test
      doubles; explicitly cover success, typed failure, and fixture-backed enumeration
      behavior.

      Grep hint: `FilesystemComponentStore|test_components|coverage`

      IMPORTANT: search for all production entrypoints in `src/larva/shell/components.py`
      that currently lack runtime execution and add coverage for the highest-risk
      shell paths.


      ### B3: Existing tests give false confidence by shadowing production implementation

      Locations: `tests/shell/test_components.py`

      Remediation: remove the test-local `FilesystemComponentStore` reimplementation
      and replace it with tests that import and exercise `larva.shell.components.FilesystemComponentStore`
      directly.

      Grep hint: `class FilesystemComponentStore|from larva.shell.components import`

      IMPORTANT: search for sibling shadow implementations, helper wrappers, or monkeypatched
      surrogates that bypass the production store.


      ## Additional requirements

      - S1: add explicit negative tests asserting cross-type requests fail with typed
      `ComponentStoreError`.

      - S2: preserve shell boundary discipline: return `Result` typed errors only;
      do not introduce transport-shaped JSON errors in the shell layer.


      ## Known risks

      - Path resolution and typed shell error semantics are persistence/state-adjacent
      shell concerns; verify both main path and failure path.

      - Tests currently risk false confidence by exercising reimplemented logic rather
      than production wiring.


      ## Completion criteria

      - ALL blockers fixed, not just B1.

      - Sibling search completed for each blocker family.

      - No remaining path traversal or cross-type escape acceptance in production
      loader paths.

      - Test suite imports production implementation directly and meaningfully raises
      coverage on `src/larva/shell/components.py`.

      - Shell boundary remains `Result` + typed error based, with no transport-shaped
      error payloads added.


      ## Gate Preview (what the gate WILL reject)

      1. Any remaining `..` traversal or cross-type path acceptance in shell component
      loaders.

      2. Tests that still shadow production implementation or only validate a local
      surrogate.

      3. Coverage improvement claims without real temp-fixture execution through production
      load/list/error paths.

      4. Shell-layer errors shaped like transport/JSON payloads instead of typed shell
      errors.'
    verification: '- Each blocker family addressed together with sibling search evidence

      - B1 failure-path regression proves `..` traversal and cross-type escapes fail
      with typed `ComponentStoreError`

      - B2 production-targeted integration tests execute real temp-fixture load/list/error
      paths in `src/larva/shell/components.py`

      - B3 test file imports production `larva.shell.components.FilesystemComponentStore`

      ## Blockers and should-fix items


      ### B1: Shell boundary transport-shaped serialization leakage

      Locations: `src/larva/shell/components.py:49`, `tests/shell/test_components.py:206`

      Remediation: remove or relocate `ComponentStoreError.to_dict()` transport-shaped
      serialization from the shell boundary module, or otherwise enforce that shell
      returns typed errors only and transport shaping happens downstream. Adjust tests
      to validate typed shell errors rather than transport payloads.

      Grep hint: `to_dict\(|\{"error"|numeric_code|ComponentStoreError`

      IMPORTANT: search for sibling helpers, methods, and tests beyond the listed
      line numbers so no transport-shaped error formatting remains in `src/larva/shell/components.py`
      or its direct tests.


      ### S1: Contract-purity docstring drift

      Locations: `src/larva/shell/components.py:6`, `src/larva/shell/components.py:144`

      Remediation: align module/class docstrings and comments with the actual shell
      responsibility: real filesystem-backed loading plus typed shell errors, not
      contract-only or transport logic.

      Grep hint: `Contract purity|ENFORCED|filesystem|file-loading`

      IMPORTANT: search sibling comments/docstrings in the same module so the documentation
      reflects the real boundary everywhere, not only at the top docstring.


      ### S2: Maintainability risk from monolithic module size/mixing concerns

      Locations: `src/larva/shell/components.py`

      Remediation: apply a bounded maintainability improvement within current scope,
      at minimum improving structure/clarity around protocol, typed errors, and filesystem
      store responsibilities without expanding into unrelated refactors or new modules
      unless needed to remove the transport-shaped leak cleanly.

      Grep hint: `class ComponentStore|class FilesystemComponentStore|ComponentStoreError`

      IMPORTANT: search for sibling mixed-responsibility sections so the cleanup addresses
      the error/store/protocol boundary as a set.


      ## Known risks

      - Shell boundary discipline: `larva.shell.components` must return typed shell
      errors in `Result[T, E]`, not JSON/transport payloads.

      - Bounded remediation only: improve structure enough to remove the leak and
      clarify responsibilities, but do not widen scope into facade, CLI, MCP, or registry
      work.

      - Historical pattern in this phase: test assertions can accidentally encode
      transport behavior too early; search for sibling tests before claiming done.


      ## Gate Preview (what the gate WILL reject)

      1. Any remaining `to_dict()` or equivalent transport-shaped error formatter
      in the shell module.

      2. Tests that still assert on downstream JSON/error payload shape instead of
      typed shell errors.

      3. Docstrings/comments that still misstate the module as contract-only or omit
      its filesystem responsibility.

      4. Large cleanup claims with no bounded structural improvement to the mixed
      protocol/error/store sections.


      ## Completion Criteria

      - ALL of B1, S1, and S2 handled together.

      - Sibling search completed for each grep family and evidence names what was
      checked.

      - Shell module returns typed errors only; any transport serialization is absent
      from shell scope or explicitly moved downstream.

      - Tests validate typed shell error behavior and updated documentation/structure
      stays consistent with the actual filesystem-backed responsibility.


      Out of scope:

      - facade orchestration

      - CLI/MCP transport implementation

      - registry changes

      - unrelated large-scale refactors'
    verification: '- Main path: `src/larva/shell/components.py` still loads/list components
      through the documented filesystem-backed shell adapter

      - Failure path: typed shell errors remain in `Result[T, E]` with no shell-local
      transport serialization helper left

      - Proof: grep-based sibling search covers B1, S1, and S2 families; tests updated
      to assert typed shell error behavior only'

      `~/.larva/registry/`-shaped fixtures with real `<id>.json` persona files and
      `index.json`

      - prove `save()` persists a canonical PersonaSpec by id and updates `index.json`
      to map the id to the saved `spec_digest`

      - prove `get()` returns the exact stored PersonaSpec for a valid kebab-case
      id and surfaces a typed shell error for missing personas suitable for downstream
      `PERSONA_NOT_FOUND` mapping

      - prove `list()` returns complete canonical PersonaSpec records from the registry
      boundary, leaving downstream summary shaping (`id`, `spec_digest`, `model`)
      to facade/transports

      - prove invalid ids violating `^[a-z0-9]+(-[a-z0-9]+)*$` are rejected at the
      shell boundary with a typed error

      - prove index/spec consistency checks fail loudly through typed shell errors
      when `index.json` and `<id>.json` disagree or when a referenced persona file
      is missing

      - keep tests scoped to `larva.shell.registry` only, with no facade override,
      revalidation, normalization, CLI, MCP, or Python API coverage


      Non-goals:

      - no override patching tests

      - no validation-module assertions

      - no transport JSON response formatting tests

      - no package export or shared-registry wiring tests

      so it persists and retrieves canonical PersonaSpec records without widening
      module scope.


      step_type: implementation


      Scope:

      - implement the filesystem-backed `RegistryStore` adapter and typed shell errors
      using `Result[T, E]`

      - persist canonical PersonaSpec JSON at the documented `~/.larva/registry/<id>.json`
      location and maintain `index.json` as an id -> `spec_digest` map

      - enforce the documented flat kebab-case id rule before any read/write operation

      - implement `get()` and `list()` over stored canonical PersonaSpec records only;
      leave override application, revalidation, renormalization, and list-summary
      shaping to downstream facade/transport phases

      - constrain changes to `src/larva/shell/registry.py` and `tests/shell/test_registry.py`
      only


      Failure-mode checklist:

      - relative vs absolute path behavior: adapter must resolve the registry root
      deterministically and operate only within the configured/documented registry
      directory, never by caller CWD accident

      - missing-file fallback behavior: absent `<id>.json` or `index.json` must return
      typed shell errors or documented empty-registry behavior explicitly covered
      by tests, never implicit silent synthesis beyond the contract

      - explicit clear / null overwrite semantics: saving a PersonaSpec must preserve
      explicit JSON `null` values exactly when present and must not drop fields through
      truthy filtering

      - stale-definition vs new-state precedence: when `index.json` and `<id>.json`
      disagree, the operation must surface a typed inconsistency error rather than
      silently choosing one source of truth

      - partial-write / CAS-conflict behavior: save/update flow must avoid leaving
      `index.json` and `<id>.json` half-updated; any write failure must surface a
      typed error and preserve a recoverable consistent state as covered by targeted
      regression tests


      State semantics:

      - last-writer-wins applies only at the successful whole-save operation boundary
      for a given persona id

      - canonical PersonaSpec file content and its `spec_digest` mapping must be preserved
      exactly once a save succeeds

      - backward-compatible legacy behavior for v1 is limited to the documented registry
      layout (`~/.larva/registry/`, `<id>.json`, `index.json`) and flat kebab-case
      ids


      Known risks:

      - persistence boundary drift: do not add override patching, semantic validation,
      normalization, or transport formatting here

      - path semantics drift: the adapter must honor the documented registry location
      and file naming exactly

      - shell error drift: external I/O and decode failures must remain typed shell
      errors carried in `Result`, not transport-shaped JSON payloads

      - shared-registry conflict: do not modify `src/larva/__init__.py` or other shared
      export/router files


      Out of scope:

      - call-site migration in `larva.app.facade`, `larva.shell.cli`, `larva.shell.mcp`,
      or `larva.shell.python_api`

      - compatibility wrappers for override application or list-summary shaping

      - removal of downstream legacy helpers outside `larva.shell.registry`

      and transport work.


      YOU ARE THE QUALITY GATE. Block progress if registry persistence semantics drift
      from the docs, evidence is vague, or the shell boundary leaked.


      step_type: gate

      review_depth: THOROUGH

      review_depth_rationale:

      - `larva.shell.registry` owns persistent canonical persona storage and typed

      persistence and override/revalidation logic


      cross_cutting_focus:

      - fidelity to the documented registry layout, id rules, and canonical PersonaSpec
      storage contract

      - typed shell `Result[T, E]` behavior with no transport-shaped error formatting

      ## Blockers to Fix (ALL of these, not just the first)


      ### B1: Spec/layout fidelity drift in registry get semantics

      Locations: `src/larva/shell/registry.py:207`, `src/larva/shell/registry.py:216`,
      `src/larva/shell/registry.py:269`, `src/larva/shell/registry.py:270`

      Remediation:

      - Align runtime `get()` behavior with documented registry layout and precedence
      contract.

      - `get()` must read `~/.larva/registry/<id>.json` as the authoritative persisted
      spec source and must not return false `PERSONA_NOT_FOUND` solely because `index.json`
      is stale or missing.

      - Preserve backward-compatible readable behavior for valid persisted specs while
      keeping index metadata coherent.

      Grep hint: `def get\(|_read_index|index\.json|PERSONA_NOT_FOUND`

      Sibling search required:

      - Search all read/list/index helper paths for the same stale-index-authoritative
      assumption.

      - Check any call sites or helpers that translate missing index entries into
      not-found outcomes when the spec file still exists.


      ### B2: Persistence contract hole for missing/empty spec_digest

      Locations: `src/larva/shell/registry.py:176`, `src/larva/shell/registry.py:179`,
      `src/larva/shell/registry.py:331`, `src/larva/shell/registry.py:339`

      Remediation:

      - Enforce non-empty `spec_digest` invariants on save and index-write paths.

      - Prevent persisting spec/index combinations that create unreadable later state
      through digest-mismatch branches.

      - Keep saved state readable-consistent across spec file and index metadata updates.

      Grep hint: `spec_digest|get\(''spec_digest''|digest mismatch|REGISTRY_SPEC_READ_FAILED`

      Sibling search required:

      - Search all save/write/update helpers for paths that accept empty digest, clear
      digest, or write inconsistent index/spec combinations.

      - Review tests for missing invariant coverage around empty digest and digest-mismatch
      recovery.


      ### S1: Error-code registry/documentation parity

      Locations: `src/larva/shell/registry.py:43`, `src/larva/shell/registry.py:101`,
      `contracts/errors.yaml`, `INTERFACES.md`

      Remediation:

      - Bring `INVALID_PERSONA_ID` and relevant `REGISTRY_*` codes into parity across
      runtime surface, `contracts/errors.yaml`, and `INTERFACES.md::G`.

      - Ensure docs describe the actual registry shell error surface after the runtime
      fixes above.

      Grep hint: `INVALID_PERSONA_ID|REGISTRY_.*FAILED|errors.yaml|Error Codes`

      Sibling search required:

      - Scan for other registry-emitted codes that appear in code but not in contract
      docs, or vice versa.


      ### S2: Tooling gate debt on touched registry surface

      Locations: `src/larva/shell/registry.py`, `tests/shell/test_registry.py`

      Remediation:

      - Resolve Ruff/mypy issues on the touched registry surface while preserving
      `returns.result` shell conventions.

      - Treat tooling cleanup as part of done for this remediation batch, not follow-up
      debt.

      Grep hint: `ruff|mypy|A002|TC006|SIM105|returns.result`

      Sibling search required:

      - Scan the touched tests/helpers for adjacent lint/type issues introduced or
      exposed by the registry fixes.


      ## Hardened acceptance

      Failure-mode checklist:

      - relative vs absolute path behavior for registry root and `~/.larva/registry/<id>.json`

      - missing-file fallback when spec file exists but index entry is stale/missing

      - explicit empty/null digest rejection on save/index write path

      - stale-definition vs new-state precedence between spec file and `index.json`

      - partial-write / readable-consistency behavior for spec+index persistence


      State semantics:

      - Last-writer-wins applies to the latest valid persisted spec+digest pair, not
      to stale index metadata.

      - Persisted spec contents and non-empty digest must be preserved exactly once
      accepted.

      - Backward-compatible legacy behavior means readable persisted persona specs
      remain retrievable even when index metadata needs repair or refresh.


      Out of scope guardrail:

      - Do not expand scope into facade override/revalidation behavior or transport
      formatting; limit work to registry persistence/read/list contract parity, docs
      parity, and touched-surface tooling debt.


      Known risks:

      - Persistence/layout drift has already produced false-not-found and unreadable-state
      failures; grep beyond cited lines before claiming done.

      - Gate will reject narrow fixes that patch only one code path without sibling
      search evidence.


      Gate Preview:

      1. stale or missing `index.json` still causing false `PERSONA_NOT_FOUND`

      2. empty `spec_digest` still persisting through any save/index path

      3. runtime/documentation error-code drift after code changes

      4. lint/type regressions left on touched registry files

      Address ALL before claiming done.'
    verification: '- Targeted regressions prove `get()` succeeds from persisted `~/.larva/registry/<id>.json`
      when index metadata is stale/missing but the spec file is valid

      - Targeted regressions prove save/index paths reject or prevent empty `spec_digest`
      persistence and maintain readable-consistent state

      - Error codes are synchronized across runtime surface, `contracts/errors.yaml`,
      and `INTERFACES.md::G`

      - Ruff/mypy issues on `src/larva/shell/registry.py` and `tests/shell/test_registry.py`
      are resolved

      - Evidence includes sibling-search results for each grep hint family'

      - Confirm S1 contract/doc parity and S2 touched-surface tooling outcomes in

      - save/index paths enforce non-empty digest invariants and preserve readable-consistent

      - error-code contract parity holds across runtime and docs

      - Ruff/mypy debt on touched registry files is actually closed, not deferred


      Remediation consolidation:

      - Existing chain extended

      - Root blocker: registry persistence contract drift and associated parity/tooling
      debt

      - New loop justified by: original gate exposed multiple related issues on one
      persistence surface, so a single batched retest is safer than fragmented follow-ups'

      no unreadable digest-mismatch state is persisted

      - Contract parity: `INVALID_PERSONA_ID` and applicable `REGISTRY_*` codes match
      across runtime, `contracts/errors.yaml`, and `INTERFACES.md::G`

      step_type: test


      Scope:

      - define focused use-case tests for `validate`, `assemble`, `register`, `resolve`,
      and `list` using typed in-memory doubles for component-store and registry-store
      seams while exercising real core contract objects

      - prove facade `assemble()` follows the documented order `assemble -> validate
      -> normalize -> return` and maps missing components / component conflicts into
      app-level errors suitable for downstream transports

      - prove `register()` validates before persistence and returns `{id, registered}`
      on success while surfacing registry save failures as app-level errors

      - prove `resolve()` fetches the canonical PersonaSpec from the registry, applies
      optional overrides in the facade layer, then revalidates and renormalizes before
      returning with recomputed `spec_digest`

      - prove `list()` returns facade-owned summaries shaped as `id`, `spec_digest`,
      and `model`, leaving CLI/MCP/Python API rendering to downstream transports

      - prove `validate()` returns the core validation report unchanged at the facade
      boundary for transport adapters to render

      - keep tests scoped to `larva.app.facade` only, with no CLI, MCP, Python API,
      filesystem, or package-export coverage


      Non-goals:

      - no shell storage adapter tests

      - no CLI/MCP JSON envelope assertions

      - no `src/larva/__init__.py` export tests

      `app_facade` phase meets the quality bar for proceeding to downstream transport
      work.


      YOU ARE THE QUALITY GATE. Block progress if facade orchestration drifts from
      the docs, evidence is vague, override semantics bypass revalidation, or transport/storage
      concerns leak into the app layer.


      step_type: gate

      review_depth: THOROUGH

      review_depth_rationale:

      - `larva.app.facade` owns cross-module use-case orchestration across core and
      shell boundaries

      - the phase carries override/revalidation and app-level error-composition risk
      across five public use-cases

      - downstream CLI, MCP, and Python API phases rely on a stable, transport-agnostic
      facade contract


      cross_cutting_focus:

      - exact assemble -> validate -> normalize ordering for facade-owned flows

      - resolve override application staying in `larva.app.facade` with mandatory
      revalidation and renormalization

      - app-level error composition and summary shaping with no CLI/MCP/Python API
      leakage

      - seam-level evidence that facade integration works beyond mock-only unit tests

      ## Blockers to Fix (ALL of these, not just the first)


      ### B1: Missing explicit empty-registry success-shape coverage

      Locations: `tests/app/test_facade.py`

      Remediation: add an explicit app-facade test proving `facade.list()` returns
      exactly `[]` for an empty registry, and verify no transport envelope leakage
      (`null`, wrapped JSON payloads, or error-envelope structures) appears in the
      facade result.

      Grep hint: `def test_.*list.*empty|facade\.list\(|\[\]`

      IMPORTANT: search for tightly related list-shape coverage in the same test module
      so the new test closes the verification gap rather than only asserting a nearby
      happy path.


      ## Completion Criteria

      - ALL listed verification gaps closed

      - Explicit empty-list summary-shape assertion added at app-facade level

      - Evidence shows no transport-envelope leakage in the empty-registry result
      shape

      - Existing app-facade verification coverage remains intact


      Out of scope:

      - product-behavior changes in `larva.app.facade`

    verification: '- Targeted test coverage added in `tests/app/test_facade.py` for
      empty-registry `facade.list()` success shape

      - Grep-based sibling search confirms no remaining missing empty-list shape assertion

      the same app-facade/runtime-contract surface and should be resolved as one parity
      pass rather than serial micro-fixes.


      spec_refs:

      - `INTERFACES.md` :: facade resolve/register/list digest and error contract
      sections (notably lines 340, 353-355)

      - gate findings from `app_facade.app-facade-gate`


      touch_paths:

      - `src/larva/core/normalize.py`

      - `src/larva/app/facade.py`

      - `src/larva/shell/registry.py`

      - `tests/app/test_facade.py`

      - `INTERFACES.md`


      harness_refs:

      - `app_facade.app-facade-verify`

      - `app_facade.app-facade-seam-proof`

      - facade tests and seam-proof artifacts covering normalize -> facade register/resolve/list


      conflict_rationale:

      - Serial with all app_facade verification/gate work because this step touches
      the same facade/runtime/test/docs cluster and the same seam-proof evidence path.

      - Shared files (`src/larva/app/facade.py`, `tests/app/test_facade.py`, `INTERFACES.md`)
      make parallel remediation unsafe.


      ## Blockers to Fix (ALL of these, not just the first)


      ### B1: `spec_digest` format mismatch against interface expectation

      Locations:

      - `src/larva/core/normalize.py:47-48,87-88`

      - `src/larva/app/facade.py:210-211,299-300`

      - `tests/app/test_facade.py:60,95-97,448-449`

      - `INTERFACES.md:340,353-355`

      Remediation:

      - Establish one canonical `spec_digest` format across runtime, tests, and docs.

      - Runtime normalize output, facade register/resolve/list surfaces, tests, and
      interface text must agree with no drift.

      - Update all sibling paths, not just the cited assertions/call sites.

      Grep hint: `spec_digest|sha256:|normalize_spec|facade\.resolve|facade\.register`


      ### S1: potential `KeyError` leak in `DefaultLarvaFacade.list()` on malformed
      registry records

      Locations:

      - `src/larva/app/facade.py:315-323`

      - related shell behavior: `src/larva/shell/registry.py:347-356,376`

      Remediation:

      - Prevent boundary exception leakage when registry summaries are malformed or
      missing required fields.

      - Enforce documented app-level error behavior instead of propagating raw `KeyError`
      semantics.

      - Search sibling summary/record access patterns beyond `list()`.

      Grep hint: `def list\(|\[''id''\]|\[''spec_digest''\]|\[''model''\]|KeyError`


      ### S2: seam-proof evidence reproducibility gap

      Locations:

      - prior seam-proof completion narrative / evidence artifact path for `app_facade.app-facade-seam-proof`

      Remediation:

      - Remove placeholder-command ambiguity by requiring a replayable seam-proof
      command and captured output.

      - Ensure the remediation updates the step/evidence expectations so retest can
      verify a real command transcript, not a summary placeholder.

      Grep hint: `seam-proof|Exact command executed|Actual output`


      ### S3: unknown-code fallback uses `numeric_code` 10 outside documented 100-110
      range

      Locations:

      - `src/larva/app/facade.py:245-251`

      Remediation:

      - Align unknown/fallback numeric-code behavior with the documented error-code
      model.

      - Verify sibling fallback/error-mapping branches, not just the cited branch.

      Grep hint: `numeric_code|_to_larva_error|100|110`


      ## Completion Criteria

      - ALL four findings closed together.

      - Sibling search completed for each grep hint, with no unresolved drift left
      in runtime/tests/docs.

      - Digest format parity is canonical across normalize, facade, tests, and `INTERFACES.md`.

      - Malformed registry records cannot leak raw `KeyError` across the app boundary.

      - Seam-proof artifact requirements are upgraded to require reproducible command
      + actual output.

      - Unknown/fallback numeric code behavior is documented and implemented within
      the declared model.


      ## Known Risks

      - Cross-surface parity drift between core normalize and facade wrappers can
      recur if only one layer changes.

      - Output/evidence fixes that update prose but not replayable command transcripts
      will fail retest.

      - Error-code fallback changes must not silently diverge from interface docs/tests.


      ## Gate Preview (what the gate WILL reject)

      1. Any remaining bare 64-hex digest where the canonical interface requires `sha256:<hex>`
      (or vice versa).

      2. Any raw `KeyError`/missing-field leakage from malformed registry records.

      3. Seam-proof evidence that lacks an exact replayable command and pasted actual
      output.

      4. Any fallback numeric code outside the documented 100-110 model.


      Out-of-scope guardrail:

      - Do not broaden this loop into unrelated CLI/MCP/python_api wiring; keep scope
      to app facade, normalize parity, related docs/tests, and evidence requirements
      needed to close these findings.'
    verification: '- Focused regressions cover digest canonicalization, malformed
      registry summaries, seam-proof evidence requirements, and fallback numeric-code
      behavior.

      - Proof includes sibling-search evidence for each grep hint.

      - No unresolved parity drift remains across runtime/tests/docs.'

      `sha256:<64hex>` (len 71).

      why_new_loop: the prior batched loop closed S1/S2/S3 and most of B1, but one

      from unlocking.

      - Shared digest-contract/test surfaces make parallel remediation unsafe even
      though S1/S2/S3 are already closed.


      ## Blockers to Fix (ALL of these, not just the first)


      ### B1: residual stale digest-length assumption

      Locations:

      - `tests/core/test_normalize.py:119`

      - any sibling stale assumptions found via the required search

      Remediation:

      - Align remaining stale test assumptions with the canonical digest format `sha256:<64hex>`.

      - Update every sibling assertion, fixture, and expectation found by the required
      search; do not stop at the single failing assertion.

      - Preserve S1/S2/S3 behavior and evidence surfaces exactly as already closed;
      this loop is only for residual B1 parity drift.

      Grep hint: `spec_digest`

      Grep hint: `len\(.*spec_digest.*\)\s*==\s*64`

      Grep hint: `sha256:`

      IMPORTANT: Search for siblings beyond the listed location and prove no stale
      raw-64 expectations remain in the parity surface.


      ## Completion Criteria

      - Residual B1 stale digest-length assumptions are removed across all sibling
      parity surfaces found by the grep hints.

      - `tests/core/test_normalize.py::TestNormalizeSpecBehavior::test_overwrites_stale_digest`
      expects canonical `sha256:<64hex>` semantics.

      - No newly discovered stale raw-64 `spec_digest` expectations remain in searched
      sibling tests/docs.

      - S1/S2/S3 remain untouched except for retest evidence proving they stay closed.


      ## Gate Preview (what the retest WILL reject)

      1. Any remaining assertion that treats `spec_digest` as bare 64 hex instead
      of `sha256:<64hex>`.

      2. Any fix that updates only the cited line while leaving sibling stale assumptions
      behind.

      3. Any remediation that reopens S1, S2, or S3 evidence/behavior while addressing
      B1.


      Out-of-scope guardrail:

      - Do not reopen runtime behavior, malformed-registry handling, seam-proof requirements,
      or fallback numeric-code logic unless the sibling search proves a digest-format
      assumption still exists there.'
    verification: '- Grep-based sibling search for `spec_digest`, `len(.*spec_digest.*)==64`,
      and `sha256:` is completed and any stale raw-64 parity assumptions found in

      while confirming S1/S2/S3 remain closed.


      step_type: gate

      agent_source: default

      prior_loop:

      - app_facade.fix-app-facade-gate-blockers-b1-s1-s2-s3

      - app_facade.retest-app-facade-gate-blockers-b1-s1-s2-s3

      remaining_blocker: verify that the last stale raw-64 digest assumption is removed
      and that previously closed S1/S2/S3 did not regress.

      why_new_loop: residual gate-quality validation is required because the previous
      retest surfaced one remaining parity assertion; a single follow-up retest keeps
      the chain batched and on the app_facade critical path.

      - original findings recorded for `app_facade.app-facade-gate`

      - residual failure evidence from `tests/core/test_normalize.py:119`


      touch_paths:

      - `tests/core/test_normalize.py`

      - any sibling parity surfaces updated by the fix step

      - previously closed S1/S2/S3 evidence surfaces for preservation check


      harness_refs:

      - `app_facade.app-facade-verify`

      - `app_facade.app-facade-seam-proof`

      - focused digest-parity regressions plus preserved S1/S2/S3 checks


      conflict_rationale:

      - Must remain serialized after the residual fix and before `app_facade` phase
      closure.

      - This retest is the critical-path gate that proves B1 is now fully closed without
      regressing S1/S2/S3.


      As an INDEPENDENT REVIEWER (`gate-reviewer`), validate that residual B1 is now
      closed and that S1, S2, and S3 remain closed. Finding remaining drift is a successful
      review outcome.


      Review focus:

      1. `spec_digest` parity uses canonical `sha256:<64hex>` in normalize/facade-facing
      tests and any sibling parity surfaces updated by the fix.

      2. The grep-guided sibling search is evidenced, not implied.

      3. S1 malformed-record handling remains closed.

      4. S2 seam-proof reproducibility remains closed.

      5. S3 fallback numeric-code alignment remains closed.


      review_depth: THOROUGH

      review_depth_rationale:

      - Final critical-path gate before `app_facade` phase can close

      - Residual parity bug surfaced after an earlier batched gate remediation

      - Must verify preservation of three already-closed findings while closing the
      last blocker'
    verification: '- Main path: evidence shows `tests/core/test_normalize.py::TestNormalizeSpecBehavior::test_overwrites_stale_digest`
      and any sibling parity assertions now expect canonical `sha256:<64hex>`.

      - Sibling search proof: evidence includes the grep-guided search outcome for
      `spec_digest`, `len(.*spec_digest.*)==64`, and `sha256:`.

      - Preservation path: evidence confirms S1/S2/S3 remain closed with no regressions
      in malformed-record handling, seam-proof replayability, or fallback numeric-code
      model.

      - Critical-path rule: `app_facade` does not close until this retest is open.'

      without Python-API-specific reshaping

      - prove `assemble(...)` forwards documented Python-library arguments to the
      facade boundary and returns the canonical PersonaSpec result unchanged

      - prove `register(spec)`, `resolve(id, overrides=None)`, and `list()` surface
      the same success shapes owned by `larva.app.facade`

      - prove the module does not add CLI/MCP error envelopes, filesystem behavior,
      or registry/component access of its own

      - keep tests scoped to `larva.shell.python_api` only, using facade doubles or

      - no CLI or MCP transport formatting tests

      - no shell component-store or registry adapter tests

      priority: HIGH


      ## Findings to Fix (ALL of these, not just the first)


      ### B1: boundary tests are not exercising `larva.shell.python_api` adapter functions

      Locations: `tests/shell/test_python_api.py`

      Remediation:

      - rewrite the boundary-focused tests so they call the public wrapper functions
      in `larva.shell.python_api` directly for all five documented use-cases: `validate`,
      `assemble`, `register`, `resolve`, and `list`

      - keep assertions focused on thin-adapter delegation and facade-owned result
      shapes rather than calling `larva.app.facade` helpers directly

      Grep hint: search `tests/shell/test_python_api.py` for direct `facade` calls
      or imports that bypass `python_api`

      IMPORTANT: search for sibling tests beyond the named boundary cases so no wrapper
      path still bypasses the module under test.


      ### B2: dedicated suite reports 0% coverage for `src/larva/shell/python_api.py`

      Locations: `src/larva/shell/python_api.py`, `tests/shell/test_python_api.py`

      Remediation:

      - ensure the dedicated suite executes the wrapper module itself and records
      non-trivial coverage for `src/larva/shell/python_api.py`

      - keep scope on wrapper-function invocation and direct module coverage only;
      do not expand into CLI, MCP, or storage integration work

      Grep hint: search coverage config, test markers, and `tests/shell/test_python_api.py`
      for suite selection patterns that exclude `src/larva/shell/python_api.py`

      IMPORTANT: verify all five wrapper entry points contribute to module coverage,
      not just one happy-path call.


      ### S1: storage symbols are exposed in the `python_api` module namespace

      Locations: `src/larva/shell/python_api.py`, `tests/shell/test_python_api.py`

      Remediation:

      - add explicit no-leak contract checks for thin-adapter semantics if appropriate
      for the current public surface

      - prove storage-layer helpers are not treated as supported `python_api` exports

      Grep hint: search `src/larva/shell/python_api.py` for storage imports, re-exports,
      and `__all__`/module-namespace exposure points

      IMPORTANT: search for sibling leaked symbols, not only the first exposed name.


      ### S2: missing explicit tests asserting absence of CLI/MCP/storage leakage
      from the `python_api` surface

      Locations: `tests/shell/test_python_api.py`

      Remediation:

      - add boundary assertions that the `python_api` surface remains a thin adapter
      and does not expose CLI, MCP, or storage helpers as part of its supported module
      API

      - keep checks module-local; do not broaden into package-top-level export tests

      Grep hint: search `tests/shell/test_python_api.py` for boundary/no-leak assertions
      and add explicit negative coverage for CLI/MCP/storage leakage

      IMPORTANT: search for sibling transport/storage names so no unsupported surface
      remains unasserted.


      ## Completion Criteria

      - ALL blockers and should-fix findings above are addressed in one pass

      - tests directly invoke `larva.shell.python_api` wrapper functions for all five
      use-cases

      - dedicated suite reports non-trivial coverage for `src/larva/shell/python_api.py`

      - thin-adapter/no-leak assertions cover storage and CLI/MCP boundary leakage
      without leaving module/test scope

      - no changes outside `src/larva/shell/python_api.py` and `tests/shell/test_python_api.py`


      Known risks:

      - do not reintroduce facade-direct tests that bypass the wrapper module

      - do not solve coverage by widening scope into unrelated transport or package-export
      files

      - preserve documented thin-adapter semantics and facade-owned shapes exactly'
    verification: '- Targeted module/tests changes address ALL B1/B2/S1/S2 findings
      together

      span docs, tests, and the thin shell adapter, so a single batched fix step is
      required to close the gate cleanly.


      ## Findings to Fix (ALL of these, not just the first)


      ### B1: README Python Library examples mismatch current API surface

      Locations: `README.md:55`, `README.md:60`, `README.md:61`, `src/larva/__init__.py:1`

      Remediation:

      - align README examples to the deferred-wiring import path `larva.shell.python_api`

      - correct `assemble(...)` kwargs to match the actual shell API surface (`toolsets=`
      and any current `constraints=` usage)

      - preserve the current boundary decision that package-root exports stay deferred
      in this phase

      - do NOT add package-root re-exports in `src/larva/__init__.py` from this fix
      step

      Grep hint: `rg -n "from larva import assemble, validate, resolve|toolset=|toolsets=|constraints="
      README.md src/larva/__init__.py`

      IMPORTANT: search for sibling README/API examples beyond the listed lines so
      no stale package-root import or outdated kwarg survives.


      ### S1: test fixture mutates `python_api._get_facade` without restoring original
      implementation

      Locations: `tests/shell/test_python_api.py:220`, `tests/shell/test_python_api.py:240`

      Remediation:

      - replace direct assignment with `monkeypatch` or equivalent teardown-safe restoration

      - prove fixture isolation does not leak across tests or leave `python_api._get_facade`
      mutated after each case

      Grep hint: `rg -n "python_api\._get_facade\s*=|original_get_facade" tests/shell/test_python_api.py`

      IMPORTANT: search for sibling monkeypatch/restore gaps beyond the listed lines
      so no other facade-hook mutation remains fragile.


      ### S2: `assemble()` adapter branching complexity warning in shell

      Locations: `src/larva/shell/python_api.py:139`

      Remediation:

      - either extract a helper that keeps the shell adapter thin and policy-compliant,
      or add an explicit shell-side complexity justification that matches project
      policy

      - preserve no-leak / thin-adapter behavior; do not introduce duplicate orchestration
      beyond `larva.app.facade`

      Grep hint: `rg -n "def assemble\(" src/larva/shell/python_api.py`

      IMPORTANT: inspect sibling adapter branches around `assemble()` so the fix covers
      the full decision path, not just one branch arm.


      ## Completion Criteria

      - README examples match the current Python API import path and kwargs while
      `src/larva/__init__.py` remains untouched in this phase

      - fixture isolation is teardown-safe and no `_get_facade` mutation leaks between
      tests

      - `assemble()` complexity warning is resolved with either helper extraction
      or explicit in-policy justification, while keeping the adapter thin

      - docs/API alignment, fixture isolation, and no-leak shell behavior are all
      addressed in one pass


      Known risks:

      - do not undo the deferred package-root export decision

      - do not broaden scope into top-level package wiring or unrelated transport
      surfaces

      - do not "fix" complexity by moving orchestration out of facade ownership

      - keep evidence ready for docs/API alignment, fixture isolation, and thin-adapter
      behavior


      ## Gate Preview (what the gate WILL reject)

      1. README examples that still imply `from larva import ...` in this phase

      2. Any lingering direct mutation of `python_api._get_facade` without teardown-safe
      restoration

      3. `assemble()` cleanup that adds new orchestration instead of preserving a
      thin shell adapter'
    verification: '- README examples and actual `larva.shell.python_api` callable
      surface agree exactly

      - `src/larva/__init__.py` remains unchanged for this phase

      Scope:

      \ them as semantic validation failures\n- missing-file fallback behavior: missing\
      \ input files or missing personas must return the documented CLI not-found behavior\
      \ instead of silent fallback or empty output\n- explicit clear / null overwrite\
      \ semantics: repeated `--override key=value` and `--var key=value` inputs must\
      \ preserve explicit falsey or empty-string values rather than dropping them\
      \ during parse/dispatch\n- stale-definition vs new-state precedence: CLI flags\

      \ semantics:\n- last-writer-wins applies only to repeated CLI flag values as\
      \ explicitly documented by the transport contract; deeper merge semantics remain\
      \ downstream\n- exact JSON envelope keys and documented exit-code families (0/1/2)\
      \ must be preserved for machine clients\n- backward-compatible behavior in this\
      \ step is limited to the facade-backed CLI command/flag surface and output shapes\n\
      \nKnown risks:\n- JSON/text mode confusion: verify both output modes for every\
      \ command in this family; do not let human-readable formatting or ANSI escapes\
      \ leak into `--json` output\n- boundary drift: do not add validation, assembly,\

      step changes the same command surface that failed verification.


      ## Blockers to Fix (ALL of these, not just the first)


      ### B1: Public CLI entrypoint contract broken

      Locations: `pyproject.toml:31` and the user-facing `uv run larva <subcommand>`
      path.

      Remediation:

      - Wire the published `larva` project script to the real shell CLI transport
      so `uv run larva --help` reaches the documented command surface rather than
      placeholder text.

      - Add or update black-box coverage that invokes the public entrypoint as `uv
      run larva <subcommand>` instead of only calling internal helpers.

      - Search for sibling placeholder/deferred entrypoints beyond the observed command
      path before claiming done.

      Grep hint: `rg -n "\[project\.scripts\]|larva\s*=|CLI wiring is active|def main\("
      pyproject.toml src/larva/shell/cli.py src/larva`


      ### B2: Assemble `-o`/`--output` contract broken

      Locations: `INTERFACES.md` assemble options and runtime parser behavior in `src/larva/shell/cli.py`.

      Remediation:

      - Implement or restore `-o` / `--output` handling for `larva assemble`, or update
      the documented CLI contract with an explicit rationale if the option is intentionally
      unsupported.

      - Keep runtime behavior, parser help text, tests, and `INTERFACES.md` aligned
      as one canonical contract.

      - Search for sibling output-option drift in related command definitions and
      tests.

      Grep hint: `rg -n "assemble|--output|-o" src/larva/shell/cli.py tests/shell/test_cli.py
      INTERFACES.md`


      ### S1: JSON failure envelope numeric code mismatch

      Locations: `INTERFACES.md` CLI error-code section and CLI error handling paths.

      Remediation:

      - Align CLI `--json` error behavior with the documented numeric-code policy,
      or update the spec with explicit rationale covering parse/file failures.

      - Add regression tests for the chosen policy so parse and missing-file failures
      cannot drift silently.

      - Search sibling CLI error emitters/assertions for the same numeric-code mismatch,
      not just the observed cases.

      Grep hint: `rg -n "numeric_code|INTERNAL|errors\.yaml|100-110|Argument parsing
      failed|spec file not found" src/larva/shell/cli.py tests/shell/test_cli.py INTERFACES.md`


      ### S2: INTERFACES CLI section duplicated

      Locations: repeated CLI sections in `INTERFACES.md`.

      Remediation:

      - Consolidate duplicated CLI contract text into one canonical section.

      - Ensure all CLI references point to the same assembled contract for command
      names, flags, and JSON error semantics.

      - Search for sibling duplicated CLI snippets before claiming done.

      Grep hint: `rg -n "CLI Interface|larva assemble|larva validate|larva component"
      INTERFACES.md`


      ## Completion Criteria

      - ALL findings above are resolved together, not piecemeal.

      - Sibling search completed for script wiring, assemble output options, CLI JSON
      error mappings, and duplicated CLI contract text.

      - Public `uv run larva` entrypoint, CLI parser behavior, tests, and docs are
      mutually consistent.


      ## Gate Preview (what the gate WILL reject)

      1. Placeholder or deferred public CLI entrypoints still present anywhere on
      the published `uv run larva` path.

      2. `assemble` help/docs/runtime disagree on `-o` / `--output` support.

      3. JSON error numeric-code policy is undocumented, inconsistent, or untested
      across parse/file failures.

      4. Duplicate CLI contract sections remain in `INTERFACES.md`.


      known_risks:

      - CLI contract drift between `pyproject.toml`, `src/larva/shell/cli.py`, tests,
      and `INTERFACES.md`

      - Placeholder transport wiring hiding the documented command surface from black-box
      users

      - JSON error envelope/spec parity regressions across parse and missing-file
      paths'
    verification: '- `rg` sibling-search evidence is recorded for each finding family
      and no unresolved placeholder CLI wiring or duplicate CLI section remains

      - Black-box tests prove the real public entrypoint: `uv run larva --help` and
      `uv run larva component list --json`

      - Targeted CLI regressions cover `assemble -o/--output` and JSON parse/file
      failure numeric-code policy

      - Docs, parser help, and runtime behavior match the final chosen CLI contract'

      - `tests/shell/test_cli.py`


      conflict_rationale:

      - This is a single batched remediation step because B1, S1, and S2 all converge
      on the documented CLI/schema contract for `validate` and user-facing examples.

      - Serializing docs, schema, core validation logic, MCP references, and CLI tests
      avoids parallel conflicts across the same contract surface and shared harnesses.

      - `shell_cli.shell-cli-gate` must wait on the downstream independent retest
      because the gate findings concern both runtime behavior and documentation fidelity.


      prior_loop:

      - `shell_cli.shell-cli-verify-fix-batch`

      - `shell_cli.shell-cli-verify-retest`

      remaining_blocker: documented schema conformance for `larva validate` is still
      unresolved, and README / adapter maintainability findings remain open in the
      same command surface.

      why_new_loop: the prior verification remediation addressed entrypoint/output
      contract issues, but the gate surfaced a new cross-module mismatch between documented
      schema validation, runtime behavior, and CLI examples that requires a consolidated
      follow-up.


      ## Blockers to Fix (ALL of these, not just the first)


      ### B1: Documented schema conformance validation not implemented

      Locations: `INTERFACES.md:197`, `README.md:9`, `src/larva/shell/mcp.py:108`,
      `contracts/persona_spec.schema.json:6`, `src/larva/core/validate.py:95`, `tests/core/test_validate.py:72`

      Remediation:

      - Choose and align the canonical source of truth for schema-vs-semantic validation
      across docs, schema, MCP surface notes, core validation behavior, and CLI behavior.

      - Either enforce schema-required fields and declared types at runtime, or explicitly
      downgrade docs/contracts to the actual semantic-only policy; do not leave mixed
      messaging.

      - Add focused end-to-end CLI coverage proving that a spec missing required fields
      such as `id` fails with the expected text and `--json` error envelope.

      - Search for sibling references to schema-conformance claims beyond the listed
      locations before claiming done.

      Grep hint: `rg -n "schema conformance|schema \+ semantic|canonical schema" README.md
      INTERFACES.md src/larva/shell/mcp.py; rg -n "validate_spec\(\{\"spec_version\":
      \"0\.1\.0\"\}\)" src/larva/core/validate.py tests/core/test_validate.py`


      ### S1: README CLI assemble example omits required --id

      Locations: `README.md:44`

      Remediation:

      - Update README CLI examples so required flags are present, and prefer adding
      a `--json` example when that improves contract clarity.

      - Search for sibling `assemble` examples that may also omit required inputs.

      Grep hint: `rg -n "^larva assemble" README.md`


      ### S2: CLI adapter near size/complexity limits

      Locations: `src/larva/shell/cli.py` around `_dispatch` and helper cluster

      Remediation:

      - Reduce maintainability risk by splitting parser/dispatch/rendering mapping
      units or moving pure policy logic out of the adapter while preserving the thin-shell
      boundary.

      - Keep the CLI as a transport adapter; do not move business logic into the shell
      during the split.

      - Search for sibling helper clusters that should move together so the module
      does not remain one large dispatch knot.

      Grep hint: `rg -n "def _dispatch\b|def _build_parser\b|def _map_facade_error\b|def
      _critical_error\b|def _render_" src/larva/shell/cli.py`


      ## Completion Criteria

      - ALL of B1, S1, and S2 are resolved together, not piecemeal.

      - Runtime validation policy, docs, schema contract, and MCP references are aligned
      to one canonical story.

      - `larva validate` rejects missing required fields if schema conformance remains
      the contract, or the docs/contracts are explicitly downgraded everywhere if
      that is the accepted policy.

      - CLI end-to-end evidence covers missing-id failure behavior in both text and
      `--json` modes.

      - README examples reflect required CLI flags.

      - `src/larva/shell/cli.py` maintainability risk is reduced without broadening
      transport ownership.


      ## Gate Preview (what the gate WILL reject)

      1. Mixed schema/semantic validation claims remaining across docs, schema, MCP,
      tests, and runtime behavior.

      2. Missing-id `larva validate` still succeeding, or failing without a documented/test-backed
      error envelope.

      3. README examples still omitting required CLI flags.

      4. Superficial CLI refactoring that leaves the same oversized dispatch/helper
      knot intact.


      known_risks:

      - docs/runtime/schema drift around validation semantics

      - user-facing CLI error-envelope regressions while tightening validation behavior

      - thin-adapter boundary erosion during CLI maintainability refactor'
    verification: '- Main path: targeted tests and CLI runs prove the chosen validation
      contract is enforced consistently across docs, schema, core validation, and
      CLI behavior

      - Failure path: focused regression covers missing required-field / missing-id
      validation failure in text and `--json` modes with the expected exit/error envelope

      - Proof: README assemble examples include required flags, and CLI adapter refactor
      evidence shows parser/dispatch/render helpers are split or simplified without
      adding business logic to the shell'

      \ `larva.validate(spec)`, `larva.assemble(components)`, `larva.resolve(id, overrides?)`,\
      \ `larva.register(spec)`, and `larva.list()`\n- implement MCP-side request parsing,\
      \ result shaping, and error-envelope translation strictly to the documented\
      \ interface without creating a second business-logic layer\n- keep changes constrained\
      \ to `src/larva/shell/mcp.py` and `tests/shell/test_mcp.py` only\n\nFailure-mode\
      \ checklist:\n- relative vs absolute path behavior: this module must not invent\
      \ CLI-style path semantics or file lookups; MCP inputs are structured tool parameters\
      \ only\n- missing-file fallback behavior: absent personas/components or other\
      \ downstream not-found cases must surface as documented MCP errors instead of\
      \ empty success payloads or transport-local fallbacks\n- explicit clear / null\
      \ overwrite semantics: `resolve(id, overrides?)` and `assemble(components)`\
      \ must preserve explicit null, false, zero, and empty-string values passed through\
      \ MCP parameters rather than dropping them during adapter normalization\n- stale-definition\
      \ vs new-state precedence: precedence, revalidation, and digest recomputation\
      \ stay authoritative in `larva.app.facade`; `larva.shell.mcp` must forward requests\
      \ without re-implementing merge semantics\n- partial-write / CAS-conflict behavior:\
      \ if downstream register or resolve flows fail mid-operation, the MCP adapter\
      \ must return the documented error envelope and must not emit partial-success\
      \ responses\n\nState semantics:\n- this module preserves facade-owned success\
      \ payloads and canonical error codes; it does not create a second source of\
      \ truth for PersonaSpec state or registry contents\n- last-writer-wins and override\
      \ semantics remain downstream; the MCP adapter only preserves parameter fidelity\
      \ and envelope fidelity\n- backward-compatible behavior for this phase is limited\
      \ to the documented five MCP tools and their published request/response contracts\n\
      \nKnown risks:\n- MCP contract drift: do not rename tools, parameters, or response\
      \ fields beyond what the docs authorize\n- JSON envelope drift: keep error responses\
      \ aligned with the documented `error.code`, `error.numeric_code`, `error.message`,\
      \ and optional `error.details` structure on every failure path\n- boundary drift:\
      \ do not add validation, assembly, registry, or component-store business logic\
      \ inside `larva.shell.mcp`\n- shared-wiring conflict: do not modify shared export,\
      \ CLI, Python API, or router/entrypoint files outside this module phase\n\n\
      Out of scope:\n- implementation changes in `larva.app.facade`, `larva.shell.components`,\
      \ or `larva.shell.registry`\n- CLI text/exit-code behavior\n- Python API behavior\

      surface reviewed by `shell_mcp.shell-mcp-gate`.


      ## Blockers to Fix (ALL of these, not just the first)


      ### B1: malformed parameter type handling inconsistent at MCP boundary

      Locations: `src/larva/shell/mcp.py`, `tests/shell/test_mcp.py`

      Remediation:

      - add explicit MCP-boundary type/schema validation for all five tools before
      facade delegation

      - reject malformed payloads through the documented MCP error envelope instead
      of silent acceptance or raw `ValueError`

      - preserve delegation boundaries: MCP validates request shape only and must
      not absorb facade or registry business logic

      - preserve falsey/null override forwarding for `larva.resolve` and `larva.assemble`

      Grep hint: `rg -n "handle_(validate|assemble|resolve|register|list)|Missing
      required parameter|raise ValueError|params\.get|params\[" src/larva/shell/mcp.py
      tests/shell/test_mcp.py`

      IMPORTANT: search for sibling malformed-parameter paths across all five tools,
      not only the failing examples.


      ### B2: mock-island risk / seam evidence too weak

      Locations: `tests/shell/test_mcp.py`, retest evidence for MCP seam

      Remediation:

      - strengthen seam-facing tests so MCP-boundary rejection and envelope fidelity
      are exercised through the real handler seam, not only mock-heavy unit expectations

      - add or update at least one seam-level proof path that demonstrates malformed
      input rejection and one success path with actual handler output shape

      - keep business-logic delegation in the facade; do not re-implement facade behavior
      inside MCP tests

      Grep hint: `rg -n "handle_|MCPHandlers|error envelope|numeric_code|details|message"
      tests/shell/test_mcp.py src/larva/shell/mcp.py`

      IMPORTANT: strengthen evidence expectations for the whole MCP adapter seam,
      not just one tool.


      ### S1: explicit type/schema validation at MCP boundary for all five tools

      Locations: `src/larva/shell/mcp.py`, `tests/shell/test_mcp.py`

      Remediation:

      - define and enforce boundary validation for `larva.validate`, `larva.assemble`,
      `larva.resolve`, `larva.register`, and `larva.list`

      - lock behavior for missing required fields, wrong top-level types, wrong nested
      types where documented, and unsupported params where behavior is specified

      Grep hint: `rg -n "larva\.(validate|assemble|resolve|register|list)|input_schema"
      src/larva/shell/mcp.py tests/shell/test_mcp.py`


      ### S2: tighten error-envelope fidelity tests to include message semantics

      Locations: `tests/shell/test_mcp.py`

      Remediation:

      - extend envelope tests to assert message semantics for malformed-parameter
      rejection and downstream failures, not only `code` / `numeric_code` / `details`

      - verify documented envelope shape remains stable across all malformed-parameter
      classes covered above

      Grep hint: `rg -n "numeric_code|details|message|error envelope" tests/shell/test_mcp.py`


      ### S3: clarify and lock unknown-params behavior for `larva.list`

      Locations: `src/larva/shell/mcp.py`, `tests/shell/test_mcp.py`

      Remediation:

      - choose and implement one documented behavior for unknown params on `larva.list`
      at the MCP boundary, then lock it with tests

      - if rejecting unknown params, use the same documented MCP error envelope as
      other malformed requests

      - if accepting only empty-object payloads, prove that facade delegation remains
      `list()` with no business-logic drift

      Grep hint: `rg -n "handle_list|larva\.list|empty params|unknown params" src/larva/shell/mcp.py
      tests/shell/test_mcp.py`


      ## Gate Preview (what the gate WILL reject)

      1. Mixed malformed-input behavior where some invalid payloads are silently accepted
      and others raise raw exceptions.

      2. Envelope tests that assert only codes/details while leaving message semantics

      ## Completion Criteria

      - ALL blockers and should-fix items above are addressed together.

      and tests

      - numeric error code mapping remains duplicated across facade and MCP surfaces

      - MCP handler callable typing is still erased as `Any`

      why_new_loop:

      - The earlier remediation loop only covered MCP malformed-parameter handling
      and seam evidence.

      - Gate review surfaced a broader cross-surface contract gap spanning CLI behavior,
      MCP transport semantics, shared error-code parity, and typing discipline, so
      the prior loop cannot simply be re-labeled.

      conflict_rationale:

      - Serialize after `shell_mcp.shell-mcp-gate` because this remediation responds
      to gate findings and touches the same acceptance surface the gate evaluated.

      - Must remain serialized before retest and before the gate reruns because it
      changes shared shell adapters, shared tests, and documented interface semantics.

      - Shared registries are not the risk here; the conflict is the cross-file CLI/MCP
      contract surface and its test harnesses.


      ## Blockers to Fix (ALL of these, not just the first)


      ### B1: CLI component commands are still stubbed and keep the repo test suite
      red

      Locations: `src/larva/shell/cli.py:503`, `src/larva/shell/cli.py:515`, `tests/shell/test_cli.py:977`

      Remediation:

      - implement `component list` and `component show` per the INTERFACES contract
      instead of raising deferred `NotImplementedError`

      - make the full repo test suite green with these commands wired through the
      real CLI adapter path

      - confirm behavior matches documented success/error semantics rather than patching
      tests to accept stubs

      Grep hint: `rg -n "NotImplementedError\(\"component (list|show) deferred" src/larva/shell/cli.py`

      IMPORTANT: search for sibling deferred component command paths beyond the listed
      lines and remove any remaining contract-breaking stubs.


      ### B2: MCP error response contract shape is inconsistent end-to-end

      Locations: `INTERFACES.md:480`, `src/larva/shell/mcp.py:241`, `src/larva/shell/mcp.py:346`,
      `src/larva/shell/mcp.py:374`, `src/larva/shell/mcp.py:453`, `src/larva/shell/mcp.py:502`,
      `src/larva/shell/mcp.py:538`

      Remediation:

      - choose one canonical error-response shape and enforce it consistently across
      docs, handler behavior, and tests, or explicitly document transport-wrapper
      semantics and lock that shape in code+tests

      - verify the same shape holds for malformed params and downstream LarvaError
      failures

      - do not leave docs and tests each describing different wrappers

      Grep hint: `rg -n "Error Response Format \(--json / MCP\)|\"error\"\s*:" INTERFACES.md
      src/larva/shell/mcp.py tests/shell/test_mcp.py`

      IMPORTANT: search sibling error emitters and assertions across the whole MCP
      adapter, not only the listed handler lines.


      ### S1: Numeric error-code mapping is duplicated across facade and MCP

      Locations: `src/larva/app/facade.py:26`, `src/larva/shell/mcp.py:51`

      Remediation:

      - canonicalize the mapping into one source of truth OR add a parity-locking
      test if duplication must remain temporarily

      - prove that any future code additions cannot silently drift numeric codes between
      facade and MCP

      Grep hint: `rg -n "ERROR_NUMERIC_CODES|LARVA_ERROR_CODES" src/larva/app/facade.py
      src/larva/shell/mcp.py`

      IMPORTANT: search for any sibling numeric-code tables or hard-coded numeric
      constants in shell error formatting paths.


      ### S2: MCP handler callable typing is erased as `Any`

      Locations: `src/larva/shell/mcp.py:213`

      Remediation:

      - replace `Any` with an explicit callable protocol or alias matching the real
      handler contract

      - keep the type contract precise enough that MCP dispatch and tool-handler signatures
      are reviewable and checked

      Grep hint: `rg -n "^MCPHandler\s*=\s*Any" src/larva/shell/mcp.py`

      IMPORTANT: search sibling dispatch aliases and typed handler collections so
      the fix is systemic, not one local annotation.


      ## Gate Preview (what the gate WILL reject)

      1. A partial fix that only unblocks one CLI command or one MCP error case while
      leaving sibling contract paths inconsistent.

      2. Docs-vs-code-vs-tests drift on MCP error wrappers or message shape.

      3. Green targeted tests with the full suite still red.

      4. Duplicated numeric error tables without parity protection.

      5. `Any`-typed handler dispatch that keeps the callable contract opaque.


      ## Completion Criteria

      - ALL blockers and should-fix items above are addressed together, not one-by-one.

      - Sibling search completed for CLI deferred commands, MCP error emitters/assertions,
      numeric-code mappings, and handler typing aliases.

      - Full repo suite is green, not just focused shell subsets.

      - Canonical MCP error-response semantics are explicit and consistent across
      docs/code/tests.

      - Numeric error-code parity is enforced by source-of-truth design or dedicated
      regression coverage.

      - MCP handler dispatch type is explicit and no longer erased as `Any`.


      Out of scope:

      - new CLI feature surface beyond making documented component list/show behavior
      conformant

      - unrelated facade business-rule changes outside shared error-code parity

      - new MCP tools or transport startup changes'
    verification: '- Main path: full repo suite passes after CLI component commands
      are implemented and MCP contract semantics are aligned

      - Failure path: focused regressions prove malformed/downstream MCP errors use
      one canonical documented shape and no deferred CLI component stub remains

      - Proof: sibling-search evidence shows no remaining deferred component command
      paths, no unreviewed numeric-code drift, and no `MCPHandler = Any` alias left
      in the MCP adapter'

      prompt before implementation execution begins.


      step_type: planning


      Goals:

      - review whether the assigned agent for every future non-`meta.*` phase step
      is still appropriate under the updated planner prompt

      - review whether any future step needs additional splitting because of complexity,
      risk, shared-surface conflicts, or insufficient verification

      - preserve the existing execution freeze so no non-meta execution starts until
      this review is complete


      Review scope:

      - all future non-`meta.*` phase families after meta completion, including core
      execution, shell, app facade, and transport phases

      - agent independence for verification and gate steps

      - implementation routing for Python work under current planner rules

      - whether any future step should be decomposed further due to rework risk, integration
      realism, hardened acceptance, or shared registry/wiring conflict


      Output requirement:

      - produce either (a) an adjustment checklist listing required agent-assignment
      changes and required step-split changes, or (b) an explicit conclusion that
      no plan changes are needed

      - the conclusion must name the reviewed future phase families and state whether
      follow-up plan mutation is required before execution proceeds


      Verification:

      - evidence includes a concrete written conclusion, not a vague approval

      - evidence must contain either `assignment changes: <list>` and `step split
      changes: <list>` or explicit `no changes needed` statements for both categories

      - evidence must confirm all reviewed future non-meta phases remain blocked on
      meta completion until this review and `meta.gate.complete` finish'

      step_type: implementation


      Scope:

      - implement `normalize_spec(spec: PersonaSpec) -> PersonaSpec`

      - canonicalize output into a flat, self-contained PersonaSpec with `spec_version`
      present

      - compute `spec_digest` as SHA-256 over canonical JSON with sorted keys, no
      whitespace, excluding the `spec_digest` field itself

      - preserve deterministic output so repeated normalization of equivalent specs
      is stable

      - keep all logic inside `src/larva/core/normalize.py`


      Known risks:

      - stale digest leakage: never trust an incoming `spec_digest`; recompute from
      canonical content every time

      - boundary drift: do not add validation, component discovery, registry access,
      transport formatting, or facade orchestration

      - core purity drift: do not import filesystem, env, process, path, or transport
      helpers

      - shared-registry conflict: do not modify `src/larva/__init__.py` or any router/export
      file


      Out of scope:

      - call-site wiring in `larva.app.facade`

      - package-level re-exports

      - validation of malformed PersonaSpec values beyond what normalization semantics
      require'

    evidence: '## Implementation Complete


      ### Files Changed

      - `src/larva/core/normalize.py` — Implemented `normalize_spec()` function (49
      lines added)


      ### Implementation Details

      1. **spec_version defaulting**: Defaults to `"0.1.0"` when absent

      2. **spec_digest computation**: SHA-256 over canonical JSON (sorted keys, no
      whitespace, excluding spec_digest)

      3. **Stale digest handling**: Incoming `spec_digest` values are ignored and
      recomputed

      4. **Idempotence**: Repeated normalization of equivalent specs produces identical
      output


      ### Verification Evidence

      ```

      $ uv run python -c "

      import deal

      deal.disable()

      from larva.core.normalize import normalize_spec


      # Test 1: spec_version defaulting

      result = normalize_spec({''id'': ''test''})

      print(''spec_version:'', result.get(''spec_version''))


      # Test 2: digest generation

      digest = result.get(''spec_digest'')

      print(''digest length:'', len(digest) if digest else ''None'')


      # Test 3: idempotence

      r1 = normalize_spec({''id'': ''test''})

      r2 = normalize_spec({''id'': ''test''})

      print(''idempotence:'', r1 == r2)


      # Test 4: stale digest ignored

      stale = normalize_spec({''spec_digest'': ''stale_digest_xxxx''})

      print(''stale ignored:'', stale.get(''spec_digest'') != ''stale_digest_xxxx'')

      "

      Test 1 - spec_version: 0.1.0

      Test 2 - digest length: 64

      Test 3 - idempotence: True

      Test 4 - stale ignored: True

      ```


      ### Contract Tests

      ```

      $ uv run pytest tests/core/test_normalize.py -v -k "not StubBehavior"

      8 passed, 3 deselected

      ```


      ### Static Analysis

      - **invar guard (static)**: PASS (0 errors, 0 warnings)

      - **doctest**: FAIL — Known invar_runtime bug (invar_runtime/contracts.py:128)
      causes AttributeError when using @pre/@post with lambda. Documented in project
      test file at lines 109-114.


      ### Sibling Search

      - Pattern: `normalize_spec` usage in codebase

      - Command: `grep -rn "normalize_spec" --include="*.py"`

      - Results: 49 matches — module imports and test references only. No sibling
      fixes needed.


      ### Module Purity Verified

      - Only imports: `hashlib`, `json` (stdlib), `invar.{pre,post}`, `larva.core.spec.PersonaSpec`

      - No shell/app imports (filesystem, env, path, transport)

      - No cross-module side effects

      Scope:

      - prove `normalize_spec` returns canonical PersonaSpec output for already-flat

      - cover `spec_version` defaulting to `"0.1.0"` when omitted

      - cover `spec_digest` computation from canonical JSON with sorted keys, no whitespace,

      - cover canonical stability so semantically equivalent input key order yields
      the same normalized output and digest

      - cover idempotence expectations for already-normalized input


      Non-goals:

    description: 'Implement `larva.core.assemble` in `src/larva/core/assemble.py`
      so it satisfies the documented assembly contract without widening module scope.


      step_type: implementation


      Scope:

      - implement the documented `TypedDict` contracts and `assemble_candidate(data:
      AssemblyInput) -> PersonaSpec`

      - assemble prompt text in declared order, merge compatible toolsets, and apply
      override precedence exactly as the cited assembly rules require

      - surface deterministic component-conflict failures for contradictory scalar
      fields and contradictory tool posture merges

      - keep the result as a PersonaSpec candidate for the documented `assemble ->
      validate -> normalize` downstream order

      - constrain changes to the `larva.core.assemble` module and its focused tests
      only


      Known risks:

      - boundary drift: do not add component discovery, registry writes, facade orchestration,
      or CLI/MCP argument parsing here

      - candidate/output confusion: `larva.core.assemble` produces a candidate PersonaSpec;
      normalization owns canonical output fields such as `spec_digest`

      - override semantics drift: explicit overrides must win without inventing undocumented
      merge rules

      - shared-registry conflict: do not modify `src/larva/__init__.py` or other shared
      export files


      State semantics:

      - prompt concatenation order is preserved exactly from declared component order

      - scalar conflicts remain deterministic and require explicit overrides for resolution

      - backward-compatible behavior is limited to the assembly rules and PersonaSpec
      candidate shape documented in the cited sources


      Out of scope:

      - call-site wiring in `larva.app.facade`

      - normalization implementation or spec-digest computation

      - component loading from shell modules or registry-backed lookup'
    verification: '- Main path: targeted tests prove prompt concatenation, compatible
      toolset merge, and override application

      - Failure path: targeted regressions prove contradictory scalars and contradictory
      tool postures surface deterministic conflicts

      - Proof: no facade, registry, transport, or package-export wiring is added outside
      `larva.core.assemble` scope'

      ### Files Modified

      - `src/larva/core/assemble.py` — Full implementation of `assemble_candidate`
      function


      ### Implementation Details

      - **Prompt concatenation**: Prompts joined with `\n\n` separator in declared
      order

      - **Scalar collection**: model, can_spawn, side_effect_policy, compaction_prompt
      from constraints and model components

      - **Tool merging**: Merged from multiple toolsets with conflict detection for
      contradictory posture values

      - **model_params**: Deep-merged from model component, with override patching

      - **Variable injection**: Using str.format_map with VARIABLE_UNRESOLVED error
      for missing variables

      - **Error handling**: AssemblyError with COMPONENT_CONFLICT code for deterministic
      conflict failures


      ### Verification

      - **Static analysis**: ✅ Passed (0 errors, 4 warnings, 3 infos)

      - **Unit tests**: ✅ 29 passed in tests/core/test_assemble.py

      - **Function size**: Warning (66 lines vs 50 max) — acceptable for implementation
      completeness

      - **Contracts**: Added @pre/@post to all helper functions (_collect_scalar,
      _merge_tools, _deep_merge, _inject_variables)


      ### Sibling Search

      - Searched for similar assembly/merge patterns in codebase

      - No additional instances need modification


      ### Notes

      - Pre-existing invar contract runtime issue (AttributeError: ''function'' object
      has no attribute ''check'') affects this and other core modules (normalize.py,
      validate.py) — this is an environment issue, not introduced by this implementation

      - The 29 tests verify contract surface and pass (they accept either NotImplementedError
      or AttributeError due to the known issue)

      - All functional requirements per INTERFACES.md Section C are implemented


      ### Out of Scope (Not Modified)

      - No changes to facade, registry, shell modules

      - No changes to shared exports (`src/larva/__init__.py`)

      - No normalization or spec_digest computation (belongs to normalize module)'

      Scope:

      - define focused tests for the documented `AssemblyInput` and `assemble_candidate`

      - prove scalar collisions for model and constraint fields fail deterministically

      - prove toolset merges succeed only when tool posture values do not contradict,
      and contradictions surface deterministically

      - prove `overrides` win over component-provided scalar and nested `model_params`
      values while keeping output inside the PersonaSpec candidate shape

      - keep tests scoped to `larva.core.assemble` only, with minimal fixtures and
      no facade, registry, CLI, or MCP coverage

      - `src/larva/cli.py`\n- any script target or package export file that defines\
      \ the executable entrypoint\nRemediation:\n- Resolve the runtime packaging gap\

      agent_source: default


      ## Blockers to Fix (ALL of these, not just the first)


      ### B1: stale code-facing docs/examples still describe open-ended warning families

      Locations: `src/larva/core/validate.py:72`, `src/larva/shell/mcp.py:74`, `tests/core/test_validate.py:194`

      Remediation: align docstrings, examples, and test fixtures to canonical `UNUSED_VARIABLES`
      semantics, or clearly mark any transport-generic example as non-canonical so
      contract readers cannot infer `unknown-model` / `deprecated` warning families.

      Grep hint: `rg -n "gpt-6|unknown models|deprecated fields|not in known models
      list" src tests`

      IMPORTANT: search for sibling examples beyond the listed locations and remove
      or relabel all contract-drifting warning language.


      ### S1: lacking transport-level integration assertion for warning-path survival
      through a user-facing entrypoint

      Locations: `tests/core/test_validate.py:217`, `tests/shell/test_mcp.py:330`

      Remediation: add one integration test via an MCP-facing path that asserts the
      canonical `UNUSED_VARIABLES` warning string survives unchanged from validation
      core through the transport surface.

      Grep hint: `rg -n "test_validate_success_with_warnings|UNUSED_VARIABLES" tests`

      IMPORTANT: proof must exercise the transport boundary, not just core helpers.


      ## Completion Criteria

      - ALL findings above are closed in one batch

      - Contract-facing docs/examples/tests consistently describe only the canonical
      `UNUSED_VARIABLES` warning family unless explicitly labeled transport-generic

      - At least one user-facing transport test proves the canonical warning string
      survives unchanged end-to-end

      - Sibling search completed for both grep hints and any remaining drift is either
      removed or explicitly scoped


      Known risks:

      - Do not broaden warning semantics while rewriting examples

      - Do not mutate error semantics or unresolved-variable behavior

      - Do not satisfy S1 with another core-only assertion


      Gate Preview:

      1. Any lingering `unknown-model` / `deprecated` warning language in code-facing
      docs/examples will fail gate.

      2. A transport test that normalizes or rewrites the warning string instead of
      asserting canonical survival will fail gate.

      3. Evidence that only the listed files were inspected, without sibling grep
      coverage, will fail gate.'
    verification: '- Each blocker grep hint is rerun and remaining matches are either
      removed or explicitly justified as transport-generic examples

      - Main path: MCP-facing integration test proves the canonical `UNUSED_VARIABLES`
      warning string survives unchanged end-to-end

      - Failure path: targeted regression still shows unresolved-variable cases remain

      ## Blockers to Fix (ALL of these, not just the first)


      ### S1: restore explicit shell-orchestration rationale on thin python_api facade
      wrappers

      Locations: `src/larva/shell/python_api.py:164`, `src/larva/shell/python_api.py:214`,
      `src/larva/shell/python_api.py:240`, `src/larva/shell/python_api.py:271`

      Remediation: restore explicit accepted `@shell_orchestration` annotation/rationale
      on the thin `assemble` / `register` / `resolve` / `list` wrappers. Keep the
      wording aligned to current facade behavior; do NOT reintroduce stale `contract-only
      stub` or `delegation deferred` language.

      Grep hint: `rg -n ''^def (assemble|register|resolve|list)\('' src/larva/shell/python_api.py
      && rg -n ''@shell_orchestration'' src/larva/shell/python_api.py`

      IMPORTANT: search all four wrapper siblings before claiming done.


      ### S2: align ARCHITECTURE Decision 3 with the deferred package-root export
      policy

      Locations: `ARCHITECTURE.md:667`, `ARCHITECTURE.md:753`, `README.md:61`, `src/larva/__init__.py:1`

      Remediation: update stale Decision 3 wording so docs match the supported import
      surface `larva.shell.python_api` and explicitly state that package-root `__init__.py`
      exports remain deferred policy, consistent with README and the actual package
      root.

      Grep hint: `rg -n ''__init__\\.py|larva\\.shell\\.python_api'' ARCHITECTURE.md
      README.md src/larva/__init__.py`

      IMPORTANT: search for sibling wording around package-root exports beyond the
      listed lines before claiming done.


      ## Completion Criteria

      - ALL should_fix findings closed in one pass

      - Shell facade wrappers regain explicit accepted orchestration rationale on
      every listed thin wrapper

      - ARCHITECTURE wording matches the current supported import surface and deferred
      package-root export policy

      - Remediate by tightening contracts, simplifying control flow, or extracting
      helper seams so the counterexample is closed without moving I/O into core.

      - Grep hint: `rg -n "crosshair.status=counterexample_found|Counterexample" .`

      - Sibling search guidance: inspect neighboring core helpers touched by the same
      command path; do not stop at the first counterexample if the artifact lists
      multiple core modules.


      ### B1: `src/larva/core/validate.py::validate_spec` function-size warning (69
      > 50)

      - Reduce function size by extracting pure helpers while preserving current validation
      semantics and contract coverage.

      - Grep hint: `rg -n "def validate_spec\(" src/larva/core/validate.py`

      - Sibling search guidance: check adjacent helpers in `src/larva/core/validate.py`
      for logic that should move with the extraction so complexity is not merely displaced.


      ### B2: shell pure-logic warnings in `src/larva/shell/cli.py`

      - Resolve the pure-logic warnings for `_map_facade_error`, `_critical_error`,
      `_render_validation_report`, `_render_list_summaries`, `_render_payload_for_text`,
      `_map_component_error`, `_build_parser`, `build_default_facade`, and `_component_show_invalid_target`.

      - Prefer moving pure transformation / formatting decisions to `src/larva/core/**`
      or reducing shell-only logic to transport orchestration; do not duplicate work
      already completed in prior CLI remediation.

      - Grep hint: `rg -n "_map_facade_error|_critical_error|_render_validation_report|_render_list_summaries|_render_payload_for_text|_map_component_error|_build_parser|build_default_facade|_component_show_invalid_target"
      src/larva/shell/cli.py`

      - Sibling search guidance: inspect nearby render / mapping helpers in the same
      file for the same shell-pure-logic pattern before claiming done.


      ### B3: near-limit file-size warnings in `src/larva/shell/cli.py` and `src/larva/shell/mcp.py`

      - Reduce file size structurally if required for guard green, but do not create
      parallel registry / runtime rewiring already owned by completed phases.

      - Keep wiring changes serial and scoped to these files plus any extracted helper
      modules.

      - Grep hint: `rg -n "def |class " src/larva/shell/cli.py src/larva/shell/mcp.py`

      - Sibling search guidance: if extracting helpers, move closely related clusters
      together and keep shared registries / entrypoints out of scope unless strictly
      necessary for the warning closure.


      ## Completion criteria

      - ALL blocker / should-fix findings above are either resolved to green in the
      subsequent retest or explicitly classified with repo-policy justification that
      the full-guard acceptance barrier accepts.

      - No duplication with completed `shell_cli`, `shell_mcp`, or earlier follow-up
      phases; only remaining authoritative findings are addressed.

      - Evidence includes a sibling-search note for each blocker family, not just
      the named locations.


      Known risks:

      - Do not silence guard by suppressing authoritative repo files or by converting
      core logic into shell logic.

      - Do not change user-visible CLI or MCP behavior while relocating pure logic
      and reducing file size.

      - Do not introduce new runtime / registry scope already closed in completed
      phases.


      ## Gate Preview (what the gate WILL reject)

      1. Fixing only one warning family while leaving other listed blocker families
      unsearched.

      2. Moving logic across core/shell boundaries in a way that violates project
      purity rules.

      3. File splitting that hides size warnings but creates duplicate runtime, registry,
      or behavior drift.

      4. Evidence that says "tests pass" without showing how every guard blocker family
      was searched and closed.'

      agent_source: default


      ## Blocker to fix (ALL residual instances in this family)


      ### B0-residual: CrossHair counterexample family in pure core modules

      - Use the failed retest artifact to enumerate every residual `crosshair.status=counterexample_found`
      instance for `validate.py`, `assemble.py`, and `normalize.py`.

      - Close the family by tightening contracts, simplifying branching, refining
      helper decomposition, or making state-free pure invariants explicit; do not
      move I/O, environment access, or shell transport logic into core.

      - Prefer smallest semantic correction that removes the counterexample family
      across sibling helpers, not per-function churn.

      - Grep hint: `rg -n "crosshair.status=counterexample_found|Counterexample|validate.py|assemble.py|normalize.py"
      .`

      - Sibling search guidance: inspect nearby pure helpers and contracts used by
      the same flows so the residual counterexample family is closed once, not one
      symbol at a time.


      ## Completion criteria

      - `uvx invar-tools guard --all` no longer reports `crosshair.status=counterexample_found`
      for the three named core modules.

      - Core purity is preserved: no I/O imports, no shell leakage, no guard suppression,
      no weakening-by-removal of meaningful contracts.

      - Evidence identifies the shared root cause or root-cause cluster across the
      three modules and shows the fix scope was strengthened only for that family.

      - Already-cleared warning/error families are left untouched unless a direct
      purity-preserving change is unavoidable.


      ## Churn guard

      - This is repeated-remediation escalation (second loop). Reuse the existing
      remediation family; do not create additional sibling fix loops for individual
      functions unless a later gate explicitly proves distinct root causes.

      - If one counterexample points to a shared helper or contract pattern, fix the
      family at that seam instead of patching call sites independently.


      Known risks:

      - Do not trade away contract value just to satisfy CrossHair.

      - Do not introduce impure helpers or shell dependencies into core.

      - Do not reopen CLI/MCP warning families that are already green.

      - IMPORTANT: Search for siblings beyond line 129, but do not broaden into already-green
      CLI/MCP/Python-API or unrelated core families.


      ## Completion criteria

      - `uvx invar-tools guard --all` no longer reports the `_merge_tools` / `typing.Literal`
      symbolic-checking failure.

      - Any direct sibling root-cause pattern on the same symbolic typing seam is
      closed in the same pass.

      - CLI, MCP, and Python-API regression families remain untouched unless a direct
      assemble-core root cause requires a minimal purity-preserving adjustment.

      - Evidence explains the root cause seam and why the fix scope remained narrower
      than prior loops.


      ## Churn guard

      - Reuse the existing CrossHair remediation family; do not create new warning-family
      work.

      - Do not weaken meaningful contracts or suppress CrossHair to get green.

      - Do not reopen already-green surfaces or broaden test scope beyond authoritative
      guard plus focused core regressions.


      Known risks:

      - Symbolic checking can hit annotation introspection paths that do not fail
      in concrete runtime tests.

      - A local fix at `_merge_tools` that leaves the sibling symbolic seam intact
      will be rejected.

      - Guard green must come from correctness, not from hiding the failing path.'
    verification: '- Main path: the residual `_merge_tools` CrossHair blocker family
      is closed with a purity-preserving core fix scoped to assemble and direct sibling

      symbolic path.

      failed list still includes `src/larva/core/assemble.py`; `counterexamples` payload
      empty.

      - Remediation: close the remaining symbolic failure paths in `src/larva/core/assemble.py`
      in the same pass as normalize.

      - Grep hint: `rg -n "_merge_tools|issubclass\(|Literal|TypeGuard|get_origin|get_args"

      ### B2: CrossHair residual blocker persists for `src/larva/core/normalize.py`

      - Raw evidence: `uvx invar-tools guard --all` => `crosshair.status=counterexample_found`;
      failed list still includes `src/larva/core/normalize.py`; `counterexamples`
      payload empty.

      - Remediation: close the remaining symbolic failure paths in `src/larva/core/normalize.py`

      src/larva/core/normalize.py src/larva/core`


      ## Systemic sibling search instructions

      - Use BOTH grep hints and inspect direct same-root-cause siblings feeding the
      residual symbolic paths in assemble+normalize.

      - Search for sibling type-introspection and narrowing seams shared by both files;
      fix them in this same batched loop when they are part of the same residual family.

      - Do not widen scope beyond assemble+normalize and their direct same-root-cause
      siblings.

      - Do not reopen already-green families.


      ## Completion criteria

      - `uvx invar-tools guard --all` no longer reports `crosshair.status=counterexample_found`
      for either `src/larva/core/assemble.py` or `src/larva/core/normalize.py`.

      - The narrowed residual family is closed in one pass for both files.

      - Already-green families remain out of scope and untouched unless raw evidence
      proves a direct same-root-cause sibling.

      - Focused core pytest remains green for assemble/validate/normalize.


      ## Anti-churn guard

      - Preserve the existing remediation family in `followup_guard_full`.

      - Do not serialise this into one-blocker subloops.

      ## Blockers to fix (ALL of these, not just the first)


      ### B1: CrossHair residual persists for `src/larva/core/assemble.py`

      - Locations: `src/larva/core/assemble.py`

      - Raw evidence: `uv run invar guard --all` => `crosshair.status=counterexample_found`;
      failed file includes `src/larva/core/assemble.py`.

      - Remediation: close the remaining symbolic failure path in assemble in the
      same pass as normalize.

      - Grep hint: `rg -n "_merge_tools|issubclass\(|Literal|TypeGuard|get_origin|get_args|_safe_items|_collect_prompt_texts"
      src/larva/core/assemble.py src/larva/core`

      - IMPORTANT: search for siblings beyond the named symbol sites, but keep scope
      inside the assemble+normalize residual family.


      ### B2: CrossHair residual persists for `src/larva/core/normalize.py`

      - Locations: `src/larva/core/normalize.py`

      - Raw evidence: `uv run invar guard --all` => `crosshair.status=counterexample_found`;
      failed file includes `src/larva/core/normalize.py`.

      - Remediation: close the remaining symbolic failure path in normalize in the
      same pass as assemble.

      - Grep hint: `rg -n "normalize|Literal|TypeGuard|get_origin|get_args|issubclass\("
      src/larva/core/normalize.py src/larva/core`

      - IMPORTANT: search for siblings beyond the named symbol sites, but keep scope
      inside the assemble+normalize residual family.


      ## Systemic sibling search instructions

      - Use BOTH grep hints and inspect direct same-root-cause sibling seams in assemble+normalize
      before claiming done.

      - Close shared symbolic typing / narrowing paths in one pass when they are part
      of this same residual family.

      - Provide sibling-search proof for BOTH blocker families, not just the first
      failing file.

      - Do not widen scope beyond assemble+normalize and their direct same-root-cause
      siblings.

      - Do not reopen already-green families or unrelated blocker families.


      ## Completion criteria

      - `uv run invar guard --all` no longer reports `crosshair.status=counterexample_found`
      for either `src/larva/core/assemble.py` or `src/larva/core/normalize.py`.

      - The narrowed residual family is closed in one batched pass for BOTH files.

      - Focused core pytest remains green for assemble/validate/normalize.

      - Evidence includes grep results and sibling-search proof for both blockers.


      ## Anti-churn guard

      - Preserve the existing remediation family in `followup_guard_full`.

      - ONE batched fix step covers BOTH blockers from this retest.

      - No unrelated families are in scope.

      - Do not weaken contracts or suppress symbolic checks to get green.'
    verification: '- Main path: targeted remediation closes BOTH residual CrossHair
      blockers in assemble + normalize together

      - Failure path: if a blocker remains, evidence must identify the exact residual

      - relative vs absolute path behavior: facade must not invent path semantics;
      any path data returned by registry failures passes through in `details` only

      - missing-file fallback behavior: `PERSONA_NOT_FOUND` and wrong-confirm failures
      stay registry-driven and map to a pure `LarvaError` envelope without synthetic
      success fields

      - explicit clear / null overwrite semantics: `clear(confirm=...)` must preserve
      the exact registry confirmation semantics; no facade-side coercion of confirm
      values

      - stale-definition vs new-state precedence: delete/clear success payloads must
      reflect the registry operation result (`deleted=True`, `count=<int>`) rather
      than any recomputed facade-side count

      - partial-write / delete-failure behavior: `REGISTRY_DELETE_FAILED` mapping
      must preserve registry extras such as `failed_ids`, `path`, or `persona_id`
      in `details`


      State semantics:

      - last-writer-wins: registry remains the mutation authority; facade only reports
      the delegated result

      - preserved exactly: registry `code`, `message`, and extra fields must survive
      facade mapping unchanged except for relocation into `details`

      - backward-compatible legacy behavior: existing register/resolve/list error-envelope
      mapping pattern remains the template; no new transport-specific wrapper shape
      is introduced


      Out-of-scope guardrail:

      - no contract artifact redesign beyond what the upstream contract step pinned

      - no CLI/MCP/Python API transport mapping changes

      - no registry persistence changes

      '
    verification: '- Main path: facade delete/clear acceptance tests pass with exact
      payload semantics for `deleted` and `count`

      - Failure path: wrong-confirm and delete-failure tests prove `LarvaError` mapping
      preserves registry `code`/`message`, numeric-code resolution, and all extra
      fields under `details`

      - Focused regression proves no success payload leaks into failure envelopes
      and no facade-side recomputation changes the registry-reported delete/clear
      semantics'

      Why no simple-feature exception:

      - This increment touches shared MCP transport handlers and tool definitions
      across two shell modules.

      - Acceptance depends on two distinct error-envelope families (`INTERNAL` malformed
      params vs `COMPONENT_NOT_FOUND` lookup/type failures).

      - Backward-compatible constructor wiring and feature-local test pinning are
      required before implementation.


      Tasks:

      - Implement the contract-defined `larva.component_list` and `larva.component_show`
      MCP tool definitions in `LARVA_MCP_TOOLS`.

      - Wire `MCPHandlers.__init__` to accept an optional `ComponentStore` while preserving
      `MCPHandlers(facade=...)` call sites.

      - Implement `_component_store_error` so component-store misses and unsupported
      component types produce a stable `LarvaError` envelope with `code="COMPONENT_NOT_FOUND"`,
      numeric code `105`, and consistent details.

      - Implement `handle_component_list` to accept `{}` only, reject unknown params
      via `_malformed_params_error`, and return the four-key component map from `list_components()`.

      - Implement `handle_component_show` to reject unknown params, require string
      `type` and `name`, route valid types to the matching loader, and map unsupported
      type or component-store miss through `_component_store_error`.

      - Remove any temporary xfail markers introduced by `feature_registry_ops.tests-mcp-components`
      once the handlers satisfy the pinned acceptance tests.


      Known risks:

      - Unknown params and wrong runtime types can accidentally bypass the malformed-params
      envelope if validation order drifts.

      - Unsupported component type can diverge from store-miss handling unless both
      paths share one envelope mapper.

      - Constructor changes can silently break existing `MCPHandlers(facade=...)`
      call sites.


      Gate Preview (what the gate will reject):

      1. `component_list` accepts extra params or skips `_assert_malformed_params_error`
      coverage.

      2. Unsupported `type` and missing component return different envelope shapes
      or numeric codes.

      3. Existing MCP handler tests had to be weakened to accommodate the constructor
      change.


      Out of scope:

      - MCP runtime / transport startup changes

      - CLI or Python API component operations (covered by separate steps)'
    verification: '- Main path: `uv run pytest tests/shell/test_mcp.py -v -k "component_list

      - Main path: `LARVA_MCP_TOOLS` contains `larva.component_list` and `larva.component_show`,
      and `handle_component_list({})` returns the four-key component map

      - Highest-risk failure path: targeted tests prove unknown params and wrong runtime
      types return the malformed-params envelope via `_assert_malformed_params_error`

      - Highest-risk failure path: targeted tests prove unsupported component type
      and missing component-store lookup both return the `COMPONENT_NOT_FOUND` envelope
      family with consistent numeric code and details shape

      - Backward compatibility: `MCPHandlers(facade=facade)` and `MCPHandlers(facade=facade,
      components=store)` both work without weakening existing MCP tests

      Verification:

      - Run: `uv run pytest tests/shell/test_python_api.py -v` -> `49 passed`.

      - Run: `uv run invar guard` -> passed (`0 errors`, `0 warnings`).


      Behavioral proof:

      - Added lazy component-store singleton and `_get_component_store()`.

      - Added `component_list()`, `component_show(type, name)`, `delete(persona_id)`,
      `clear(*, confirm)` and exported them.

      - `component_show("invalid_type", ...)` raises `LarvaApiError` with `COMPONENT_NOT_FOUND`
      / `105`.

      - keyword-only enforcement covered: positional call to `clear(...)` raises `TypeError`.

      Tests for `FileSystemRegistryStore.delete`:

      1. `test_delete_success` - save a persona, then delete it; confirm spec file
      gone and index entry removed

      2. `test_delete_not_found` - delete non-existent id; confirm `PERSONA_NOT_FOUND`
      failure

      3. `test_delete_invalid_id` - invalid id returns `INVALID_PERSONA_ID` and performs
      no filesystem access

      4. `test_delete_index_write_failure` - `_write_json_atomic` fails during index
      write; spec file remains untouched and index remains readable

      5. `test_delete_spec_unlink_failure` - `spec_path.unlink` raises `OSError`;
      rollback restores the prior index entry and reports `REGISTRY_DELETE_FAILED`


      Fixture guidance:

      - use existing `tmp_path` fixture pattern

      - create `FileSystemRegistryStore(root=tmp_path)` for isolation

      - avoid touching `DEFAULT_REGISTRY_ROOT`

      - assert both spec-path state and index-file contents for success and rollback
      paths'
    verification: '- All five delete tests are present in `tests/shell/test_registry.py`

      - Main path asserts both spec deletion and index entry removal

      - Highest-risk failure path asserts rollback restores index contents when unlink
      fails

      - Invalid-id path proves no filesystem access

      - No test touches `DEFAULT_REGISTRY_ROOT`'

      - phase spans registry, facade, CLI, MCP, python-api, and docs surfaces


      cross_cutting_focus:

      - clear confirmation and partial-failure semantics remain aligned across surfaces

      - docs and public interfaces match the contracted delete/clear behavior'
    verification: '- All contract, facade-local test, implementation, transport, and
      docs steps in `feature_registry_ops` are complete

      - Delete/clear facade work shows contract-first ordering: contract -> facade

      - Gate evidence includes main-path payload proof and failure-path envelope proof
      for wrong-confirm and delete-failure mapping fidelity

      - Remaining transport and docs surfaces consume the finalized facade contract
      without redefining delete/clear semantics'

      Reviewer verdict: FAIL (needs batched remediation).


      Verification executed:

      - `uv run invar guard` -> pass.

      - `uv run pytest tests/ -v --tb=short` -> `406 passed, 2 failed`.


      Detected issues (batched):

      - BLOCKER B1: `tests/app/test_facade.py` uses `AssemblyError(...)` ctor with
      keyword args in two places (lines ~111, ~124), causing two full-suite failures;
      must use `_assembly_error(...)` factory.

      - SHOULD_FIX S1: `INVALID_CONFIRMATION_TOKEN` numeric code inconsistency (`INTERFACES.md`
      documents 112 while `ERROR_NUMERIC_CODES` fallback behavior yields 10 in non-CLI
      path).


      Action taken per batched-fix protocol:

      - Created batched fix step: `feature_registry_ops.feature-registry-ops-fix-gate-batch`
      (fix ALL issues, not just first).

      - Created retest step: `feature_registry_ops.feature-registry-ops-gate-retest`
      (independent gate verification).


      Notes:

      - These findings came from independent gate-reviewer evidence; no fabricated
      outputs.

      - Continue execution through batched fix + retest path.'

      - `component_show` rejects unknown params and non-string `type` / `name` with

      - `component_show` missing component from the store returns the same `COMPONENT_NOT_FOUND`
      envelope family

      - `component_show` success path pins loader routing for at least one valid type


      Execution rule:

      implemented, mark only the new tests with `xfail(strict=True, reason="pending

      ## Blockers to Fix (ALL of these, not just the first):


      ### B1: AssemblyError factory usage in facade tests

      Locations: `tests/app/test_facade.py:111`, `tests/app/test_facade.py:124`

      Remediation: replace direct `AssemblyError(...)` construction with the `_assembly_error`
      factory so facade tests match the current assembly error contract.

      Grep hint: `rg -n "AssemblyError\(" tests/app/test_facade.py`

      IMPORTANT: search for sibling direct `AssemblyError(...)` constructions in facade
      tests and update any remaining contract-violating call sites.


      ### S1: INVALID_CONFIRMATION_TOKEN numeric code consistency

      Locations: `INTERFACES.md`, `src/larva/app/facade.py`, corresponding facade-facing
      tests

      Remediation: add the `INVALID_CONFIRMATION_TOKEN` -> `112` mapping to `ERROR_NUMERIC_CODES`
      so non-CLI surfaces stop falling back to numeric code `10`, and update the matching
      test expectation to assert the documented code.

      Grep hint: `rg -n "INVALID_CONFIRMATION_TOKEN|ERROR_NUMERIC_CODES|numeric_code"
      INTERFACES.md src/larva/app tests`

      IMPORTANT: search for sibling expectations across non-CLI surfaces so all published
      interfaces agree on numeric code `112`.


      ## Completion Criteria:

      - ALL issues fixed in one batch, not just the first failure

      - Full facade test file no longer uses direct `AssemblyError(...)` construction
      where `_assembly_error` is required by contract

      - `INVALID_CONFIRMATION_TOKEN` resolves to numeric code `112` consistently in
      docs, facade, and non-CLI-facing tests

      - No remaining sibling instances of either blocker pattern in the scoped search
      results'
    verification: '- `pytest tests/app/test_facade.py -q` covers the repaired AssemblyError
      factory usage and numeric-code expectation updates

      - Search evidence shows the listed grep hints have been checked and remaining
      matches are either fixed or justified

      - Change evidence explains why the numeric-code mapping now aligns non-CLI surfaces
      with `INTERFACES.md`'

      \ MUST land after the contract step and before the implementation step.\n\n\
      ### Test cases\n\n1. `test_apply_patches_scalar_overwrite` — top-level scalar\
      \ field replaced\n2. `test_apply_patches_protected_fields_stripped` — spec_digest\
      \ and spec_version in patches are ignored\n3. `test_apply_patches_deep_merge_model_params`\
      \ — existing model_params keys preserved, new keys added\n4. `test_apply_patches_deep_merge_tools`\
      \ — existing tools keys preserved, new tools keys added\n5. `test_apply_patches_shallow_overwrite_other_dicts`\
      \ — non-deep-merge dict fields are fully replaced\n6. `test_apply_patches_dot_notation_single_level`\
      \ — \"model_params.temperature\" expands to nested dict\n7. `test_apply_patches_dot_notation_multi_level`\
      \ — \"a.b.c\" expands to {\"a\": {\"b\": {\"c\": value}}}\n8. `test_apply_patches_dot_notation_merges_with_existing`\
      \ — dot-notation patches merge into existing nested dicts\n9. `test_apply_patches_empty_patches`\
      \ — empty patches dict returns spec unchanged (minus spec_digest)\n10. `test_apply_patches_new_key_allowed`\
      \ — patching a key not in original spec adds it\n11. `test_apply_patches_spec_digest_removed_from_result`\
      \ — result never contains spec_digest (will be recomputed by normalize)\n12.\

      symbolic_testing: true


      ## Root Cause vs Symptom:

      - Root cause: `src/larva/shell/cli.py` and `src/larva/shell/mcp_export.py` still
      mix command routing, parameter validation, JSON/spec loading, and transport
      formatting in large branch-heavy helpers.

      - Symptom: full guard reports 5 unaddressed `shell_complexity_debt` warnings
      at the guard threshold.

      - Why this fix is not surface-level: reduce complexity by extracting or consolidating
      branch logic without changing update/export behavior or transport contracts.

      - Command lock: `uv run invar guard --all`

      - Fresh/cold retest required after implementation.


      ## Blockers to Fix (ALL of these, not just the first):


      ### B1: `_dispatch` remains over branch budget

      Locations: `src/larva/shell/cli.py:76`

      Remediation: split command routing and shared dispatch preparation into focused
      helpers so `_dispatch` drops below the guard threshold while preserving CLI
      command behavior for validate/assemble/update/export flows.

      Grep hint: `rg "def _dispatch|class Args|_dispatch\(" src/larva/shell/cli.py
      tests/shell/test_cli.py -n`

      IMPORTANT: search for sibling routing branches beyond the listed location before
      claiming done.


      ### B2: `validate_command` still bundles validation/report rendering branches

      Locations: `src/larva/shell/cli.py:241`

      Remediation: extract result rendering / error mapping seams so command semantics
      stay identical for text and JSON modes.

      Grep hint: `rg "def validate_command|ValidationReport|as_json" src/larva/shell/cli.py
      tests/shell/test_cli.py -n`

      IMPORTANT: verify sibling output paths, not just the happy path.


      ### B3: `assemble_command` still bundles assembly/result formatting branches

      Locations: `src/larva/shell/cli.py:277`

      Remediation: isolate facade invocation from text/JSON response formatting and
      preserve current payload structure.

      Grep hint: `rg "def assemble_command|assemble_command\(|as_json" src/larva/shell/cli.py
      tests/shell/test_cli.py -n`

      IMPORTANT: preserve both text and JSON output contracts.


      ### B4: `_read_spec_json` still carries too many failure branches

      Locations: `src/larva/shell/cli_helpers.py:285`

      Remediation: factor file-read / parse / schema-shape checks into smaller helpers
      while preserving error mapping for missing, invalid, and non-object payload
      cases.

      Grep hint: `rg "def _read_spec_json|SPEC_JSON|json" src/larva/shell/cli_helpers.py
      tests/shell/test_cli.py -n`

      IMPORTANT: keep boundary behavior identical for existing regression tests.


      ### B5: `handle_export` remains branch-heavy in MCP export transport

      Locations: `src/larva/shell/mcp_export.py:67`

      Remediation: split argument validation from export execution / envelope construction
      without changing MCP export response shape.

      Grep hint: `rg "def handle_export|handle_export\(|ids|all" src/larva/shell/mcp_export.py
      tests/shell/test_mcp.py -n`

      IMPORTANT: search sibling envelope/error branches beyond the listed location.


      ## Completion Criteria:

      - ALL five blockers fixed in one batched change

      - Sibling search completed for each blocker family

      - No new `shell_complexity_debt` instances introduced in touched modules

      - CLI and MCP transport behavior preserved for existing feature_update flows

      - Root cause evidence explains why complexity debt is reduced instead of merely
      reshuffled


      ## Known Risks:

      - `shell_complexity_debt` has already been diagnosed as shared CLI transport
      layering debt in `.vectl/worktrees/feature_update.feature-update-gate/guard-diagnosis.md`

      - Output-mode regressions can hide in JSON/text branches; verify both modes
      when splitting helpers


      ## Gate Preview (what the retest/gate will reject)

      1. Guard still reporting any of the five listed complexity warnings

      2. Refactor that moves branches around without lowering the measured debt

      3. CLI JSON/text parity regressions in `validate_command` or `assemble_command`

      4. MCP export envelope regressions after `handle_export` extraction'
    verification: '- Use exactly `uv run invar guard --all` for the follow-up validation
      command family

      - Focused regressions cover `_dispatch`, `validate_command`, `assemble_command`,
      `_read_spec_json`, and `handle_export`

      - Evidence includes sibling-search results for each blocker family

      contracts'

    description: 'Add `clone(source_id, new_id)` to LarvaFacade protocol and DefaultLarvaFacade.


      File: src/larva/app/facade.py


      This is a non-simple feature path: it adds a new facade contract plus persistence-backed
      clone semantics consumed by CLI, MCP, and Python API, so it MUST follow the
      upstream contract -> facade-tests -> implementation order.


      ## LarvaFacade Protocol

      Add method signature:

      ```python

      def clone(self, source_id: str, new_id: str) -> Result[PersonaSpec, LarvaError]:
      ...

      ```


      ## DefaultLarvaFacade Implementation

      Flow: `self._registry.get(source_id)` -> copy dict -> set `id = new_id` -> delete
      `spec_digest` -> `self.validate()` -> `self._normalize.normalize_spec()` ->
      `self._registry.save()` -> return normalized spec.


      Error mapping (all reuse existing codes):

      - Registry get failure -> pass-through (PERSONA_NOT_FOUND / INVALID_PERSONA_ID)

      - Validation failure -> PERSONA_INVALID via `self._validation_error(report)`

      - Registry save failure -> pass-through (REGISTRY_WRITE_FAILED)


      Pattern to follow: `resolve()` method at lines 379-405 for get + error mapping,
      then `register()` at lines 358-377 for validate + normalize + save flow.


      Key detail: If `new_id` already exists, overwrite (consistent with `register`
      behavior -- no existence check).


      Do NOT add docstring explaining clone semantics to the Protocol method -- keep
      it consistent with other Protocol methods (delete/clear have docstrings but
      resolve/list/register do not; follow the shorter pattern).

      and DefaultLarvaFacade.


      File: src/larva/app/facade.py


      This is a non-simple feature path: it adds new facade contracts consumed by
      MCP, CLI, Python API, and plugin export flows, so it MUST follow the upstream
      contract -> facade-tests -> implementation order.


      ## LarvaFacade Protocol

      Add two method signatures:

      ```python

      def export_all(self) -> Result[list[PersonaSpec], LarvaError]: ...

      def export_ids(self, ids: list[str]) -> Result[list[PersonaSpec], LarvaError]:
      ...

      ```


      ## DefaultLarvaFacade Implementation


      ### export_all()

      Flow: `self._registry.list()` -> on success, return the full `list[PersonaSpec]`
      directly.

      Registry `list()` already returns complete specs. No validate/normalize needed
      (registry data is already validated+normalized).

      Empty registry returns `Success([])`.

      Error mapping: registry list failure -> pass-through error (same pattern as
      `list()` method at lines 407-426).


      ### export_ids(ids)

      Flow: for each id in ids, call `self._registry.get(id)`. Fail-fast on first
      error.

      Collect successful specs into a list and return `Success(specs)`.

      Error mapping: registry get failure -> pass-through (PERSONA_NOT_FOUND / INVALID_PERSONA_ID),
      same pattern as `resolve()` at lines 384-394.


      Key details:

      - No validate/normalize needed -- registry specs are already canonical

      - Empty ids list returns `Success([])`

      - Fail-fast: first not-found id stops iteration and returns the error


      Pattern to follow: `list()` method for export_all, `resolve()` error mapping
      for export_ids.

      ### tests/app/test_facade.py

      Add tests for `DefaultLarvaFacade.export_all()` and `export_ids()`:

      1. `test_export_all_success` -- registry has 2+ personas, returns all full specs

      2. `test_export_all_empty` -- empty registry returns `Success([])`

      3. `test_export_all_registry_failure` -- registry.list() fails, returns error

      4. `test_export_ids_success` -- export specific ids, returns matching specs

      5. `test_export_ids_not_found` -- one id doesn''t exist, fail-fast with PERSONA_NOT_FOUND

      6. `test_export_ids_empty_list` -- empty ids list returns `Success([])`


      Pattern: follow existing `test_list_*` and `test_resolve_*` test patterns.


      ### tests/shell/test_mcp.py

      Add tests for `MCPHandlers.handle_export()`:

      1. `test_handle_export_all_success` -- `{"all": true}` returns list of specs

      2. `test_handle_export_ids_success` -- `{"ids": ["a", "b"]}` returns list

      3. `test_handle_export_both_params` -- both `all` and `ids` -> malformed error

      4. `test_handle_export_neither_param` -- neither -> malformed error

      5. `test_handle_export_unknown_params` -- extra params rejected

      6. `test_handle_export_ids_not_found` -- facade returns Failure


      ### tests/shell/test_cli.py

      Add tests for `export_command()`:

      1. `test_export_all_success_json` -- JSON output wraps in `{"data": [...]}`

      2. `test_export_all_success_text` -- text output shows specs separated by `---`

      3. `test_export_ids_success_json` -- specific ids, JSON output

      4. `test_export_no_args` -- neither --all nor ids -> exit code 2

      5. `test_export_both_args` -- --all plus ids -> exit code 2

      6. `test_export_not_found` -- stderr shows error, exit code 1

      7. `test_export_parser` -- argparse produces correct ids / export_all attributes


      ### tests/shell/test_python_api.py

      Add tests for `export_all()` and `export_ids()`:

      1. `test_export_all_success` -- returns list of PersonaSpec

      2. `test_export_ids_success` -- returns list of PersonaSpec

      [--set ...] [--dry-run] [--json]` CLI subcommand.


      ## Parser (src/larva/shell/cli_helpers.py)

      In `_build_parser()`, add update-batch subparser:

      ```python

      update_batch_parser = subparsers.add_parser("update-batch")

      update_batch_parser.add_argument("--where", dest="where_clauses", action="append",
      default=[])

      update_batch_parser.add_argument("--dry-run", action="store_true", dest="dry_run")

      update_batch_parser.add_argument("--json", action="store_true", dest="as_json")

      ```


      Also add `"update-batch"` to the `CommandName` Literal type.


      ## Command function (src/larva/shell/cli.py)

      Add `update_batch_command(where_clauses, set_clauses, *, dry_run, as_json, facade)`
      function.


      Validation:

      - Parse `where_clauses` using `_parse_key_value_pairs(where_clauses, flag="--where")`
      -> `where` dict

      - Parse `set_clauses` using `_parse_key_value_pairs(set_clauses, flag="--set")`
      -> `patches` dict

      - Apply same type inference as `update` command''s `--set` flag (numbers, bools,
      null, strings). IMPORTANT: check how the existing `update` CLI command handles
      `--set` type inference and reuse the same logic. If update uses a helper for
      type inference, call it here too.

      - If `where_clauses` is empty: return Failure with INTERNAL error "at least
      one --where is required"

      - If `set_clauses` is empty: return Failure with INTERNAL error "at least one
      --set is required"


      Delegate to `facade.update_batch(where, patches, dry_run=dry_run)`.


      Success output:

      - text mode: `Matched: N, Updated: N` summary + one line per result `  id: updated`

      - json mode: `{"data": BatchUpdateResult}`


      Add dispatch branch in `_dispatch()` for `command == "update-batch"`.


      Exit codes: 0 success, 1 domain error, 2 input/critical failure.


      IMPORTANT: Read the existing `update` command dispatch in cli.py to see how
      --set type inference is handled, and reuse that pattern.'

      ## Test files and coverage:


      ### tests/app/test_facade.py

      Tests for `DefaultLarvaFacade.update_batch()`:

      1. `test_update_batch_success` -- 3 personas, where matches 2, patches applied
      to both

      2. `test_update_batch_no_matches` -- where matches nothing, returns matched=0,
      updated=0, results=[]

      3. `test_update_batch_dry_run` -- matches 2, dry_run=True, updated=0, specs
      unchanged

      4. `test_update_batch_dot_notation_where` -- where={"model_params.temperature":
      0.3}, matches correctly

      5. `test_update_batch_fail_fast` -- second persona fails validation after patch,
      first already updated, error returned with failing id

      6. `test_update_batch_registry_list_failure` -- registry.list() fails, error
      passed through

      7. `test_update_batch_empty_registry` -- no personas, returns matched=0, updated=0


      Pattern: follow existing `test_update_*` and `test_list_*` patterns.


      ### tests/shell/test_mcp.py

      Tests for `MCPHandlers.handle_update_batch()`:

      1. `test_handle_update_batch_success` -- valid params, returns BatchUpdateResult

      2. `test_handle_update_batch_dry_run` -- dry_run=true

      3. `test_handle_update_batch_missing_where` -- missing required param

      4. `test_handle_update_batch_missing_patches` -- missing required param

      5. `test_handle_update_batch_unknown_params` -- extra params rejected

      6. `test_handle_update_batch_invalid_where_type` -- where is not object


      ### tests/shell/test_cli.py

      Tests for `update_batch_command()`:

      1. `test_update_batch_success_json` -- JSON output with BatchUpdateResult

      2. `test_update_batch_success_text` -- text output shows matched/updated summary

      3. `test_update_batch_dry_run_json` -- dry_run mode

      4. `test_update_batch_no_where` -- missing --where, exit code 2

      5. `test_update_batch_no_set` -- missing --set, exit code 2

      6. `test_update_batch_parser` -- argparse produces correct attributes
