Loki Mode

Added

• loki review --ultra (issue #168): an explicit, opt-in, on-demand cloud
  multi-agent code review that wraps the upstream claude ultrareview
  subcommand. Paid cloud operation, billed by Anthropic, separate from local
  model spend. Strictly opt-in: the disclosure prints every time, an interactive
  TTY prompts with default NO, and a non-interactive shell without --yes (or
  LOKI_ULTRAREVIEW=1) refuses with exit 2 and makes zero cloud calls. Findings
  are advisory and do not block the completion gate. Capability-gated: if the
  installed claude lacks ultrareview it prints an honest upgrade note and
  exits. No dollar amount is shown (no price API exists); the disclosure states
  the cost class only.
• loki plan now states the trust moat (issue #166): a short, honest block
  ("Why this estimate is trustworthy") naming verified completion (the
  completion council blocks "done" without a real diff and green tests) and cost
  honesty (the quoted model is the model the run dispatches and the dashboard
  reports). Mirrored as a structured moat field in loki plan --json.
• --allowedTools positive allowlist for reviewer/adversarial/council subcalls
  (issue #167), opt-in via LOKI_REVIEW_ALLOWLIST=1, default OFF and
  byte-identical default argv on both routes. Complements the v7.33.0
  --disallowedTools denylist with a least-privilege read/inspect allowlist
  (Read, Grep, Glob, read-only git and shell). Deny-precedence verified against
  the live CLI and the Claude Code permissions docs, so allowlist and denylist
  ship together. Gated on CLI support.

Fixed

• Non-git codebase signature hardening (issue #171): trees over the content
  budget (or file-count cap LOKI_PRD_SIG_CONTENT_MAXFILES, default 20000) now
  use a sampled head+tail content hash (files-sampled:) instead of the old
  content-blind files-shallow: listing, so most same-size edits on large
  non-git trees are detected and a stale generated PRD is no longer silently
  reused. Batched (xargs -0 -n 64) to avoid per-file fork cost. A stored
  pre-upgrade files-shallow: signature with a matching listing + count still
  decides reuse on the first post-upgrade run. Git projects unaffected. Residual
  honest gap (a same-size edit confined to the middle of a file larger than 8KB)
  documented in the signature docblock.
• Nightly parity-drift workflow (issue #173) now normalizes environment-only
  lines (disk space GB, the runtime-route block, the LOKI_LEGACY_BASH warning,
  dashboard pid, summary counts) before diffing the bash and Bun doctor output,
  matching the normalization already in scripts/local-ci.sh. This stops
  env-only false positives while still surfacing real route-logic divergence.
