[Docs] Add lifecycle verification GAP report and remediation blocks

[zoomote]

​Created by Roomote. Follow up by mentioning @roomote, in the web UI, or in Discord.

What changed

• Added an exhaustive-but-qualified lifecycle GAP report covering state owners, persistence, scheduling, delegation, streams/events, and tool-state boundaries.
• Ranked 38 findings under stable LIFE-GAP-* IDs and grouped them into eight remediation workstreams with complexity, engineering risk, dependencies, critical path, parallel workstreams, and closure evidence.
• Added a 1-SP remediation block register. In this report, 1 SP means one small independently reviewable modeling/documentation increment with one bounded behavior/property, production mapping, applicable checker change, test/CI evidence, objective acceptance criteria, and explicit exclusions.
• Mapped every LIFE-GAP-001..038 exactly once to a primary LIFE-BLK-* owner; dependencies reference shared prerequisites without duplicating ownership.
• Added four separately named optional FANOUT-BLK-* blocks outside serial baseline closure.
• Kept the planned two-sibling fan-out checker outside the baseline lifecycle:model-check/CI umbrella and strengthened orphan cleanup to require released permits.
• Removed all engineer-day and duration estimates; blocks and clusters use only review scope, relative complexity, risk, dependencies, implementation shape, and objective evidence.
• Grounded audit criteria in primary TLA+, Quint, Alloy, Jepsen, and SQLite references; issue links remain historical provenance only, and the root README has no tracker link.

Why this change was made

The remediation backlog needs increments small enough to review and launch without pretending shared primitives are independent or converting story points into duration estimates. Stable block ownership and dependency annotations make sequencing mechanically checkable while preserving the detailed parent GAP contracts.

Impact

There is no production or UI behavior change. The new register provides 38 baseline modeling/documentation blocks and four optional future fan-out blocks. Completing a block improves one bounded evidence unit and does not imply its parent production gap is closed.

📝 Summary

Summary by CodeRabbit

• New Features

  • Added a task fan-out protocol model checker covering reachable states, safety rules, expected actions, and known failure scenarios.
  • Added a command to run fan-out protocol checks.
  • Expanded provider handoff verification to confirm task-local execution modes are preserved.

• Documentation

  • Added a comprehensive lifecycle verification gap report and remediation block register.
  • Clarified lifecycle model boundaries, coverage requirements, failure semantics, fan-out behavior, and audit criteria.
  • Added links connecting related lifecycle and protocol documentation.

Walkthrough

The pull request expands lifecycle-model documentation, adds a 38-gap audit and remediation register, introduces bounded fan-out verification, registers its npm script, and adds a provider handoff witness for task-local mode selection.

Changes

Lifecycle verification

Layer / File(s)	Summary
Lifecycle model and gap audit docs/architecture/task-lifecycle-model.md, docs/architecture/task-lifecycle-gap-report.md, docs/architecture/native-tool-call-parser-scoping-model.md, docs/architecture/task-cleanup-protocol-model.md	The documentation defines bounded submodels, coverage boundaries, lifecycle gaps, audit evidence, and links between related models.
Lifecycle remediation register docs/architecture/task-lifecycle-remediation-blocks.md	The register maps LIFE-GAP-001 through LIFE-GAP-038 to remediation blocks, production symbols, verification evidence, dependencies, and acceptance criteria.
Fan-out protocol model check scripts/check-task-fanout-protocol.ts, package.json	A bounded breadth-first checker explores two-child fan-out states, validates invariants and known invalid states, and is exposed through a new npm script.
Provider handoff witness scripts/check-provider-handoff-scheduler.ts	The provider handoff check verifies that task-local mode does not resolve to the shared provider mode and reports the witness in its summary.

Priority: ➖ Normal

Estimated code review effort: 3 (Moderate) | ~30 minutes

Merge Risk: 🔵 Low · up to 3d79d

The lifecycle check may miss delegated-mode regressions affecting tool validation and environment details, but this change does not itself alter production behavior.

Resolution

Complete the required pull request template.

Full details: Linked Issues check

Explanation

Issue #1625 requires three task-local mode reads and related automated coverage. At the reviewed head, getEnvironmentDetails still destructures mode from clineProvider.getState(). presentAssistantMessage still destructures mode from provider state for tool processing. The linked scripts/check-delegated-mode-readers.ts file is absent. The PR changes listed in the summary add lifecycle documentation and unrelated model-check scripts, but they do not add the required reader fixes or unit tests.

Resolution

Change getEnvironmentDetails, validateToolUse call sites, and custom tool execution in presentAssistantMessage to use cline.getTaskMode(). Add the required focused unit tests. Add and run the pure-TypeScript delegated-mode lifecycle check in lifecycle:model-check.

Full details: Out of Scope Changes check

Explanation

The PR adds a 38-finding lifecycle gap report, remediation-block register, broad lifecycle architecture changes, an optional fan-out checker, and a provider-handoff witness. These changes do not implement or verify the three task-local mode readers required by issue #1625. The provider-handoff witness checks selectHandoffExecutionContext, not getEnvironmentDetails, validateToolUse, or custom tool execution.

[zoomote]

Reconciled #1626 with #1623 and runtime-fix PR #1625 in commit fed91bb86. The checker now claims only selector/write-side coverage, retains a divergent task/provider-mode witness for the downstream obligation, and the traceability docs and PR description explicitly assign environment/tool reader correctness to #1625. pnpm lifecycle:model-check, typechecking, lint, and the full test suite pass; no UI proof applies.

[zoomote]

Completed the lifecycle coverage audit in commit 70d7ac60a. Every protocol area and issue row now states its evidence class, production/model relationship, bounds, omitted consumers, and remaining obligations; passed is explicitly defined as bounded success rather than issue closure. README now links the authoritative tracker, and child model docs link back to its audit. pnpm lifecycle:model-check, typechecking, lint, and the full test suite pass; visual proof is not applicable.

[zoomote]

Completed the live-state traceability re-audit in commit 48644f714. Retained open #1469, #1021, #1623, #369/#372, and #612 because production or enforcement gaps remain. Moved closed #1453/#1279, #921, #920, and #1468 to verified history, preserving all bounded/proxy limitations and redirecting adjacent open risks to their active issues. pnpm lifecycle:model-check, typechecking, lint, and the full test suite pass; visual proof is not applicable.

[zoomote]

Re-scoped #1626 to documentation/formal-model audit only at 20aebc49f. All runtime, shared-type, scheduler, production-test, and Zoo-Code-Docs changes introduced during the attempted implementation were reverted; the net PR diff contains only architecture docs, model-check scripts, and command wiring. The root README has no lifecycle tracker link. pnpm lifecycle:model-check, typechecking, and lint pass; visual proof is not applicable.

[zoomote]

Completed the repository-wide lifecycle-verification GAP report in 8d00b944f. It inventories lifecycle owners, persistence/mutation/queue/delegation/stream/event boundaries, copied vocabulary, tests/models/CI, and ranks 34 stable LIFE-GAP-* items with severity, confidence, impact, witnesses, dependencies, and objective closure criteria. Primary TLA+, Quint, Alloy, Jepsen, and SQLite references are translated into repository-specific audit rules. Formatting, relative link targets, pnpm lifecycle:model-check, typechecking, and lint pass; scope remains documentation/formal-model-only and visual proof is not applicable.

[zoomote]

Completed the subtask todo audit in 378abeeb5. Normal creation does not copy the parent list: child todos are explicit model-supplied new_task.todos, parsed into a fresh list and forwarded as initialTodos. The distinct IDE-side gap is that initial todos are process-local and disappear on rehydration before the first persisted update_todo_list; no existing model covers todo ownership, publication scoping, or rehydration equivalence. Added LIFE-GAP-035 with reproduction controls, impact, boundary, and objective closure criteria. Formatting, pnpm lifecycle:model-check, typechecking, and lint pass; no runtime or UI changes were made.

[zoomote]

Completed the tool-state ownership audit in 63150c68e. LIFE-GAP-035 now covers durable tool-originated child initialization, with initial todo loss as its confirmed witness; distinct 036–038 cover uncorrelated approval edits, singleton partial-handler state, and lossy tool-ID correspondence across persistence/execution/replay. PR #1625's mode bug can influence prompt/validation and therefore model output indirectly, but no production path transfers parent todos based on mode. No new green checker was added because these boundaries lack faithful unified production transitions; explicit witness/closure criteria are retained instead. Formatting, link targets, pnpm lifecycle:model-check, typechecking, and lint pass.

[zoomote]

Completed the portfolio remediation plan in 7ea3edd9e. All 38 gaps are assigned to eight root-cause programs with calibrated effort/risk, subsystem ownership, dependencies, objective evidence, safe consolidation boundaries, critical path, four parallel workstreams, quick wins, architectural programs, and a first tranche. Recommended serial-contract portfolio scale is 85–145 engineer-days; full fan-out is 105–175. Formatting, link targets, pnpm lifecycle:model-check, typechecking, and lint pass; scope remains documentation/model-only.

[zoomote]

Completed fan-out scope separation in 64a0ec8e7. Production’s normal reducer/provider path enforces singular awaited-child ownership, and the production-backed lifecycle checker models it with three slots/depth 12; cross-host stale-write witnesses remain explicit exceptions requiring baseline fixes. The no-production-import two-sibling model is now excluded from lifecycle:model-check/CI and runs only via fanout-protocol:model-check. Baseline closure remains 85–145 engineer-days; optional fan-out is separately ticketed incremental scope of 20–35 days after prerequisites. Both model commands, typechecking, lint, formatting, and link checks pass.

Updated in de94fa58e: removed all engineer-day/duration estimates from docs and PR metadata, retaining only relative complexity, risk, dependencies, ordering, and closure evidence. Also strengthened optional fan-out orphan cleanup to require an empty permit-owner set. Both actionable inline CodeRabbit threads were replied to and resolved. Baseline/optional model checks, typechecking, lint, formatting, link targets, and an explicit estimate-pattern scan pass.

CodeRabbit’s top-level linked-issue and out-of-scope checks were intentionally not followed: they misidentify related PR #1625 as this PR’s governing issue and conflict with the explicitly requested documentation/formal-model scope. No repository PR template exists; the PR body retains the required fallback sections and accurately describes the net diff.

[zoomote]

Completed in 6b0b83932: added 38 primary 1-SP modeling/documentation blocks, one per LIFE-GAP-001..038, grouped under P1–P8 with explicit shared dependencies and no duplicate ownership. Added four optional FANOUT-BLK-* blocks outside serial baseline closure. A mechanical check confirms 38/38 exact mappings; baseline and optional model checks, typechecking, lint, formatting, link targets, and estimate-pattern checks pass. The remote branch advanced with main during delivery, so it was merged non-destructively and pushed at a8afae774. Current CodeRabbit state has no unresolved actionable threads.

Exercise the delegated reader paths in the provider handoff witness

selectHandoffExecutionContext asserts only the selector result. presentAssistantMessage reads mode from shared provider state before calling validateToolUse, and getEnvironmentDetails derives currentMode from shared provider state. Neither path is invoked or modeled by this witness. The check can therefore pass while these readers use shared provider mode instead of task-local mode. Add focused assertions for both reader paths with distinct modes.
