Commit Message: fix(cli): disallow mixing legacy and v3 plan workflows
Branch: fix/prevent-legacy-v3-mixing

Background and Context

The CleverAgents CLI currently supports two distinct plan workflow systems:

Legacy Plan Workflow — uses human-readable plan names ("64-bit port plan"):
- Commands: agents tell, agents build, agents apply (without plan ID)
- Storage: Separate legacy plan system (PlanService)
- Status: Deprecated but still functional
v3 Plan Lifecycle — uses ULID identifiers (01HXM8C2ZK4Q7C2B3F2R4VYV6J):
- Commands: agents plan use, agents plan execute <PLAN_ID>
- Storage: New lifecycle-based plan system (PlanLifecycleService)
- Status: Authoritative per specification (docs/specification.md)

These two systems operate independently with completely separate storage, making it impossible for a v3 command to find a plan created by a legacy command. However, the current implementation provides misleading deprecation warnings that suggest users can simply replace legacy commands with v3 equivalents, when in reality:

A plan created via agents tell -n "64-bit port plan" ... exists only in the legacy system
Running agents plan execute "64-bit port plan" will fail with "Plan not found" because v3 commands only accept ULIDs and only search v3 storage
The current warning message ("Use 'agents plan execute <plan_id>'") doesn't explain this fundamental incompatibility

Root Cause Analysis

Issue #1: Misleading Deprecation Guidance

Lines 112-115 in plan.py define _LEGACY_DEPRECATION_MSG which states: "Use 'agents plan use [project]' for the v3 lifecycle"
This guidance is correct in direction but lacks crucial context about the workflow incompatibility
Users see the warning and reasonably attempt to port their plan name to v3, leading to "Plan not found" errors

Issue #2: No Validation to Catch Workflow Mixing

agents plan execute accepts any string as plan_id (line 1859 in plan.py)
When given a non-ULID string like "64-bit port plan", it searches v3 storage
The error message is generic: "Plan '{plan_id}' not found" — doesn't explain the likely cause (mixing workflows)

Issue #3: Specification-Implementation Gap

The specification (docs/specification.md, line 74) claims "Top-level plans carry a namespaced name"
The CLI doesn't implement name-based plan lookup for v3 plans
This creates confusion about whether plans should be referenceable by name

Current Behavior

When a user attempts to run a v3 command with a legacy plan name:

$ agents tell -n "64-bit port plan" "Devise a plan..."
Warning: 'tell' is a legacy command. Use 'agents plan use <action> [project]' for the v3 lifecycle.
[Plan created in legacy system]

$ agents plan execute "64-bit port plan"
Error: Plan '64-bit port plan' not found

Problem: The error message doesn't explain:

That "64-bit port plan" is a legacy plan, not a v3 plan
That v3 plans require ULIDs, not names
That the two systems are incompatible and cannot be mixed
What the user should actually do (either convert the plan or use legacy commands throughout)

Expected Behavior

When a user attempts to mix legacy and v3 workflows, the system should:

Detect the mismatch — recognize when someone passes a non-ULID identifier that might be a legacy plan name
Provide actionable guidance — explain the workflow incompatibility clearly
Prevent silent failures — don't just say "Plan not found"; explain the likely root cause
Force intentional choice — require users to explicitly choose either legacy OR v3 workflow, not both

Ideal error message:

Error: Plan 'legacy-plan-name' not found.

The v3 plan lifecycle expects a ULID (e.g., 01HXM8C2ZK4Q7C2B3F2R4VYV6J), 
not a plan name. Possible causes:

1. You created a plan with 'agents tell' (legacy workflow) and are trying 
   to reference it with 'agents plan execute' (v3 workflow).
   
2. You referenced the wrong plan ID.

The legacy 'agents tell' and 'agents build' workflows are deprecated. 
Migrate to the v3 workflow:
  - Use 'agents plan use <action> <project>' to create a plan
  - Use 'agents plan execute <plan_id>' to execute it
  - Use 'agents plan apply <plan_id>' to apply changes

Legacy commands operate in a separate system and cannot be mixed with v3 commands.

Acceptance Criteria

agents plan execute, agents plan apply, and agents plan status all validate that the provided argument is a valid ULID before querying the database
When a non-ULID identifier is provided to v3 commands, the error message explains the workflow incompatibility and suggests migration to v3 (per spec)
The deprecation warnings in legacy commands no longer suggest direct 1:1 command replacements; instead, they explain the workflow migration path
CONTRIBUTING.md is updated with a new section explaining that legacy and v3 workflows are mutually exclusive and cannot be mixed
No user ever receives a misleading error message that suggests a simple command substitution will work (e.g., "just use plan execute instead")
All error messages are tested to ensure they provide actionable guidance (see subtask: add error message tests)

Supporting Information

Relevant Code Locations

Legacy deprecation warnings: src/cleveragents/cli/commands/plan.py:112-115 (_LEGACY_DEPRECATION_MSG)
Legacy command implementations: src/cleveragents/cli/commands/plan.py:588-1244 (tell, build, apply, new, current, list, cd, continue commands)
v3 command implementations: src/cleveragents/cli/commands/plan.py:1517-2056 (use_action, execute_plan)
Plan ID validation: Currently missing — src/cleveragents/cli/commands/plan.py:1859-1933 (execute_plan function)
Specification glossary: docs/specification.md:74 (Plan definition claiming "Top-level plans carry a namespaced name")

This issue relates to and should be fixed before:

Any enhancements to plan name-based lookup (would need spec clarification first)
Any further deprecation of legacy commands (error messages must be clear first)

Test Case Demonstrating the Problem

# Setup
cd /tmp/test-cleveragents
agents init --yes

# Create a legacy plan
agents tell -n "legacy-test-plan" "Write a test function" 2>&1 | grep -i warning

# Try to use v3 commands with the legacy plan name
agents plan execute "legacy-test-plan" 2>&1  # Error: Plan 'legacy-test-plan' not found
# ^ Current error doesn't explain the workflow incompatibility

# Try with invalid ULID
agents plan execute "not-a-ulid" 2>&1  # Same unhelpful error message

Subtasks

Validation: Implement ULID format validation for all v3 commands (execute, apply, status, etc.)
- Add a reusable validation function: _validate_plan_ulid(plan_id: str) -> str
- Raise ValidationError with actionable message if not a valid ULID
Error Messages: Enhance error handling in v3 plan commands
- Update error message in execute_plan() at line 1956 to explain workflow incompatibility
- Update error message in _lifecycle_apply_with_id() at line 924 similarly
- Add guidance about migrating from legacy to v3
Legacy Warnings: Revise deprecation messages in legacy commands
- Update _LEGACY_DEPRECATION_MSG to avoid suggesting 1:1 command swaps
- Explain that users must choose either legacy OR v3 workflow
- Point to migration documentation
Documentation: Update CONTRIBUTING.md
- Add section: "Workflow Choice: Legacy vs. v3 Plan Lifecycle"
- Explain that the two systems are incompatible
- Document migration path from legacy to v3
- Provide example workflows for both
Tests: Add tests for error messages
- Test that ULID validation catches non-ULID input (behave test)
- Test that error messages are actionable (robot framework integration test)
- Test that legacy plan names are clearly identified as legacy when mistakenly used with v3
Specification Clarification (stretch/follow-up)
- File follow-up issue to clarify whether v3 plans should support name-based lookup
- If yes, define the namespaced name format and ULID precedence rules
- Update specification accordingly

MoSCoW classification: MoSCoW/Should Have

Rationale: Preventing users from mixing legacy and v3 plan workflows is important for usability and developer experience. The specification defines the v3 Plan Lifecycle as authoritative, and the legacy system is deprecated. However, this is an error message improvement — the system still functions correctly (it just gives confusing errors). This improves quality but doesn't block core functionality. Should Have.

Additionally, this issue is missing a milestone. Assigning to v3.7.0 since it relates to CLI workflow improvements and the plan lifecycle, which is part of the TUI/CLI polish scope.

PR #1577 Review: Changes Requested

PR #1577 has been reviewed and changes are requested before it can be merged. Key issues found:

ULID validation logic is incorrect — accepts hyphens and invalid Crockford Base32 characters (I, L, O, U)
Tests use subprocess (integration-style) but are in features/ (unit test location) — should test _validate_plan_ulid() directly or move to robot/
First test scenario is broken — Given step doesn't create a real plan, so the "succeeds" assertion will always fail
Validates auto-discovered plan IDs unnecessarily in lifecycle_apply_plan()
Missing type annotations in step definitions
Unused import (not_ from hamcrest)
Missing plan status validation per acceptance criteria
PR metadata issues — missing Type/ label, milestone, wrong state label

Test architecture — Step definitions use direct function calls and Typer CLI runner (not subprocess)
Auto-discovered plan IDs — Validation only applied to user-provided input (in else branches)
Deprecation warning tests — Fixed to use CLI runner to capture console.print output (not warnings.catch_warnings)
Unused imports — Removed warnings, plan_module, and ProjectLink unused imports
plan status validation — Added ULID validation to plan_status command
plan errors and cancel — Added ULID validation to all v3 commands

Implementation Notes — Issue #1560: ULID Validation & Legacy/v3 Workflow Guard

Commit at time of writing: d7db1c9282c7cd7d39c8ca84b56d3bc90dba13da

Implementation Summary

All subtasks for issue #1560 have been completed. The implementation prevents users from accidentally mixing legacy and v3 plan workflows by introducing ULID format validation on user-supplied plan IDs and improving error messages across all relevant v3 CLI commands.

Modules/files created or modified:

src/cleveragents/cli/commands/plan.py — Primary implementation file. Added the ULID regex constant, validation error message constant, and the _validate_plan_ulid() helper function. Updated _LEGACY_DEPRECATION_MSG, added inline deprecation warnings to tell and build, and wired validation into six v3 commands.
features/plan_ulid_validation.feature — New BDD feature file with 20 scenarios covering ULID validation, per-command CLI integration, and deprecation warning behaviour.
features/steps/plan_ulid_validation_steps.py — New step definitions file with full type annotations, implementing all steps for the above feature.
CONTRIBUTING.md — New section: "Workflow Choice: Legacy vs. v3 Plan Lifecycle", documenting the distinction between legacy and v3 plan workflows for contributors.

Design Decisions

1. ULID Regex: Crockford Base32 (`^[0-9A-HJKMNP-TV-Z]{26}$`, case-insensitive)

The regex ^[0-9A-HJKMNP-TV-Z]{26}$ (applied case-insensitively) was chosen over simpler alternatives such as str.isalnum() or a plain [A-Z0-9]{26} pattern.

Rationale: The ULID specification uses Crockford Base32, which deliberately excludes the characters I, L, O, and U to avoid visual ambiguity. A plain isalnum() check would silently accept strings containing those characters, producing false positives. The Crockford-correct regex rejects them, and also rejects hyphenated UUIDs (which users might mistakenly supply when confusing legacy plan IDs with v3 ULIDs).

Alternatives rejected:

str.isalnum() and len == 26 — Too permissive; accepts invalid ULID characters.
UUID regex — Wrong format entirely; v3 plan IDs are ULIDs, not UUIDs.
No validation, rely on database 404 — Produces a confusing "not found" error with no guidance on the root cause (workflow mismatch).

2. Validation Scope: User-Provided IDs Only

ULID validation is applied exclusively in the else branches that execute after auto-discovery logic (i.e., only when the user has explicitly supplied a plan ID). Auto-discovered plan IDs (retrieved via database queries) are never validated.

Rationale: Auto-discovered IDs are already known-good values from the database. Validating them would add overhead with no benefit and could introduce false failures if the database ever contains IDs in a transitional format. Restricting validation to user input is the correct trust boundary.

3. Error Message Format

Error messages follow the pattern:

Plan '{plan_id}' not found. Plan IDs must be 26-character Crockford Base32 ULIDs ...

The message intentionally opens with "Plan '{plan_id}' not found." to match the existing error format already present in the codebase, ensuring consistency for any tooling or tests that parse error output. It then appends a detailed explanation of the ULID requirement and the legacy/v3 workflow incompatibility.

Rationale: Preserving the existing prefix avoids breaking downstream error-handling while still providing actionable guidance to the user.

4. Commands Validated

Validation was added to all six v3 commands that accept user-provided plan IDs:

execute_plan
_lifecycle_apply_with_id
lifecycle_apply_plan
plan_status
plan_errors
cancel_plan

Legacy commands (tell, build) were not given ULID validation (they do not accept plan IDs in the same way) but were updated with improved inline deprecation warnings via _LEGACY_DEPRECATION_MSG.

5. BDD Test Strategy: Typer CLI Runner for Integration, Direct Calls for Unit Tests

CLI integration tests use the Typer CliRunner (not subprocess) to invoke commands in-process. Unit tests for _validate_plan_ulid() call the function directly.

Rationale: CliRunner provides fast, hermetic CLI testing without spawning subprocesses, while still exercising the full Typer argument-parsing and error-handling stack. Direct function calls for the unit tests keep them isolated from CLI concerns and faster to execute.

Discoveries and Assumptions

Hyphens in legacy IDs: It was discovered during implementation that users migrating from legacy workflows sometimes supply hyphenated UUID-style strings as plan IDs. The Crockford regex correctly rejects these, and the error message explicitly calls this out.
Case-insensitivity: The ULID spec permits lowercase input that maps to uppercase Crockford characters. The regex is applied case-insensitively to accommodate this, matching spec behaviour.
Auto-discovery path: The existing auto-discovery logic (database lookup when no ID is supplied) was confirmed to bypass the new validation entirely, as intended. No changes were needed to the auto-discovery code paths.
_LEGACY_DEPRECATION_MSG constant: This constant pre-existed but was updated as part of this work. The update is intentional and aligned with the new CONTRIBUTING.md section.
Open question: There is no migration utility to help users convert legacy plan references to v3 ULIDs. If this becomes a support burden, a follow-on issue should be raised to add a plan migrate subcommand or similar.

Workarounds and Deviations

No significant workarounds were required.
The scope of _LEGACY_DEPRECATION_MSG updates (covering tell and build inline warnings) was slightly broader than the original issue description implied, but was necessary for consistency and was kept within the same PR (#1577).
Follow-on work identified:
- A plan migrate utility (or equivalent) to help users convert legacy plan references to v3 ULIDs — not in scope for this issue.
- Consider adding ULID validation to any future v3 commands that accept user-provided plan IDs, following the same else-branch pattern established here.

Test Results

BDD scenarios: 20 scenarios written across features/plan_ulid_validation.feature, covering:
- Valid ULID acceptance (multiple formats including lowercase)
- Invalid ULID rejection (hyphens, wrong length, invalid characters including I, L, O, U, empty string)
- Per-command CLI integration for all 6 validated commands
- Deprecation warning presence on tell and build
Unit tests: Direct calls to _validate_plan_ulid() for both valid and invalid inputs.
All scenarios and unit tests pass at commit d7db1c9282c7cd7d39c8ca84b56d3bc90dba13da.

Risk Mitigations

Risk	Mitigation
Regex rejects valid ULIDs (false positives)	Regex was verified against the Crockford Base32 spec and tested with both valid and boundary-case inputs in BDD scenarios.
Auto-discovered IDs incorrectly validated	Validation is structurally restricted to `else` branches after auto-discovery; auto-discovered IDs never reach `_validate_plan_ulid()`.
Error message format breaks existing tooling	New message preserves the existing `"Plan '{plan_id}' not found."` prefix; only appends new content.
Legacy command users confused by new warnings	`_LEGACY_DEPRECATION_MSG` updated to clearly direct users to the v3 workflow and the new CONTRIBUTING.md section.
