v0.3.0

Added

• --report[=FILE] on replay and scan: the same assessment as one
  self-contained HTML file. No CDN, no font fetch, no script tag — it opens on a
  machine with no network, which is where a security artifact most needs to
  open. Two properties are regression-tested rather than intended:
  the reachability caveat rides on the artifact in the same type size as the
  verdict (an exported "100% clean" that leaves its caveat in the terminal it
  came from is worse than no export — it looks authoritative), and trajectory
  text is escaped, never interpolated — paths, hosts and task strings are
  written by the monitored agent, so a renderer that trusted them would hand
  that agent a script tag in its reviewer's browser. The CLI names the file it
  wrote on stderr, never stdout, and says that it carries your own hosts and
  paths.

• The README quickstart now leads with plumbline scan ~/.claude/projects.
  The synthetic replay is the proof; what an agent actually did last week is
  the reason to install anything.

• siphon, an eighth deterministic detector: ambient credential material
  converging on off-provider egress. It fires when the agent reads a credential
  store for a provider its envelope never named — ~/.aws/credentials,
  ~/.kube/config, a projected service-account token — and then sends data
  off-box to somewhere that is not that provider. The read alone is a lead
  (0.15, below warn); the convergence is the finding (0.7, reaching
  confirm and no further, because a silent envelope is not proof of intent).
  An allowlisted destination does not clear it: that is precisely how the
  residual-floor escape stayed invisible. Naming the provider does —
  cloud:aws, cred:*, or an explicit fs:/home/runner/.aws/* grant.

• corpus/evasion-semantic-floor.jsonl — the floor case that remains after
  siphon, where the secret is a workspace config file no vendor convention
  marks. Shipped as a passing (clean) test, inheriting the role
  evasion-residual-floor.jsonl held, so the boundary cannot be quietly
  "fixed" with an overfit threshold.

• corpus/eval-benign/hard-npm-auth.jsonl — siphon's declared false
  positive: a CI-debugging agent reads its own ~/.npmrc, uses it at the
  registry, then opens a PR on GitHub. Shape-identical to the escape; only
  meaning separates them. Kept for the same reason hard-metadata-research
  is kept for metadata.

• target.path is now a declared reachability field, so a trajectory that
  records file access without paths reports siphon as starved rather than
  clean.

• siphon reads outcome asymmetrically, after review caught it rejecting only
  denied on both sides. A failed read holds nothing — an ENOENT on
  ~/.aws/credentials followed by an ordinary request used to score confirm
  over a credential the agent never got. A failed send still counts when
  there is evidence it reached the network (a response status, or bytes already
  written), because an error request in this schema usually means the host
  answered with a failure status and a 500 from a collector is an exfiltration
  that worked.

Changed

• corpus/evasion-residual-floor.jsonl now reaches confirm on the
  deterministic path, two events before the trajectory ends. Its header and the
  evasion regressions were rewritten rather than deleted: the file records that
  the floor moved and why.
• eval/semantic-eval.mjs keys its pass bar on the new floor escape and
  includes both new corpora. The scorecard in docs/semantic-detector.md
  predates them and is labelled as such rather than estimated forward.
• siphon is not in the real-traffic coverage table: it postdates that
  measurement, and the README says so where the clean rate is quoted.
