[DIC-22] repair-spec CLI — DecaySignal → RepairSpec (#6033)

[an0mium]

Slice

Adds the aragora repair-spec CLI subcommand — the operator surface for DIC-22 (verified replacement pipeline, issue #6033). Reads a DecaySignal JSON file (produced by aragora decay-monitor --json signals[]) and emits a bounded RepairSpec via aragora.epistemic.repair.propose_repair.

Every other DIC-20/21 item already has a CLI command; DIC-22 was the only one in the 20–22 range missing an operator surface despite having a complete Python implementation (aragora/epistemic/repair.py) already on main.

Files changed (3, net +399 LOC — no deletions):

• aragora/cli/commands/dic22_repair.py — new CLI command implementation (120 lines)
• aragora/cli/parser.py — registers _add_repair_spec_parser() with # DIC-22 / #6033 (+34 lines)
• tests/cli/test_dic22_repair.py — 20 hermetic tests (245 lines)

Gating

• Flag: ARAGORA_REPAIR_PIPELINE_ENABLED (default OFF; same flag as the existing repair.py module)
• Without the flag: exits 1 and names the flag in stderr — no silent fallback
• live_swap repair_kind is permanently blocked (enforced both by propose_repair() inside repair.py and by an early guard in the CLI)
• No effect on live queue paths, dispatch, or boss loop
• vision-layer label only; not boss-ready or autonomous

Tests

tests/cli/test_dic22_repair.py — 20 tests, all pass

Flag gating (3): flag off → exit 1 + stderr names flag; truthy values (1/yes) → exit 0
Input validation (4): missing file, bad JSON, missing code_unit_id, live_swap blocked → exit 1
Text output (3): spec_id / code_unit_id / repair_kind visible in stdout
JSON output (3): valid JSON with required keys; report_only has empty provenance_hash
Repair-kind routing (4): report_only always passes; shadow_candidate/pr_candidate 64-char hash
_parse_decay_signal unit tests (3): claim/crux extraction, missing id raises, score clamped

Run locally with:

ARAGORA_REPAIR_PIPELINE_ENABLED=1 uv run --extra test pytest tests/cli/test_dic22_repair.py --noconftest -v

Validation

• uv run --extra test pytest tests/cli/test_dic22_repair.py --noconftest — 20 passed
• uv run --extra test ruff check aragora/cli/commands/dic22_repair.py tests/cli/test_dic22_repair.py aragora/cli/parser.py — clean
• uv run --extra test mypy aragora/cli/commands/dic22_repair.py tests/cli/test_dic22_repair.py — clean

Out of scope

• DIC-23 dialectical runtime loop CLI (a separate slice, branch dic-23-dialectical-loop-cli)
• Arena debate-driven repair proposal (downstream of RepairSpec, DIC-22 second milestone)
• Live queue routing or dispatch changes
• boss-ready promotion (blocked until proof-first Foreman gate opens)
