fn-23-zgk.2 Update ID regex patterns

fn-23-zgk.2 Update ID regex patterns

Description

Update all regex patterns that parse epic/task IDs to support variable-length slugs while maintaining backwards compatibility with existing formats.

Size: M Files:

• plugins/flow-next/scripts/flowctl.py (4 regex locations)
• plugins/flow-next/scripts/hooks/ralph-guard.py (1 location)

Approach

Already done in fn-23-zgk.1: flowctl.py regex updates at lines 629, 1781, 4214, 6496 using:

r"^fn-(\d+)(?:-[a-z0-9][a-z0-9-]*[a-z0-9]|-[a-z0-9]{1,3})?(?:\.(\d+))?$"

Remaining work: Update ralph-guard.py receipt parsing at lines 276, 280, 284:

# Current: r"plan-(fn-\d+(?:-[a-z0-9]{3})?)\.json$"
# New: r"plan-(fn-\d+(?:-[a-z0-9][a-z0-9-]*[a-z0-9]|-[a-z0-9]{1,3})?)\.json$"

Same pattern for impl and completion matches

Key context

The regex must accept all three formats:

• fn-1 (legacy numeric only)
• fn-1-abc (current 3-char random)
• fn-1-add-oauth-login (new slugified)

Pattern explanation:

• [a-z0-9] - must start with alphanumeric
• (?:[a-z0-9-]*[a-z0-9])? - optional middle with hyphens, must end alphanumeric
• This prevents leading/trailing hyphens in slug

Acceptance

• parse_id("fn-1") returns valid (legacy format) - done in fn-23-zgk.1
• parse_id("fn-1-abc") returns valid (3-char format) - done in fn-23-zgk.1
• parse_id("fn-1-add-oauth") returns valid (slug format) - done in fn-23-zgk.1
• parse_id("fn-1.2") returns valid (legacy task) - done in fn-23-zgk.1
• parse_id("fn-1-abc.2") returns valid (3-char task) - done in fn-23-zgk.1
• parse_id("fn-1-add-oauth.2") returns valid (slug task) - done in fn-23-zgk.1
• parse_id("fn-1-") returns invalid (trailing hyphen) - done in fn-23-zgk.1
• parse_id("fn-1--double") returns invalid (double hyphen) - done in fn-23-zgk.1
• File glob patterns match all three formats - done in fn-23-zgk.1
• ralph-guard receipt parsing works with slug format
• All 45 smoke tests pass

Done summary

Updated ralph-guard.py parse_receipt_path() regex to support variable-length slugs. All 45 smoke tests pass.
