Morgan Westlee Lunt 3b9df61600 code-modernization: fix findings from adversarial audit
Code/security:
- extract-rules.js: guard null agent() verdicts in the verify + P0 loops
  (a skipped/dead referee made {rule,v:null} survive .filter(Boolean) and
  then crashed on v.injectionSuspected / v.every) — sibling scripts already
  had the guard.
- topology viewer XSS: the map injector embedded untrusted JSON (node names
  from filenames, etc.) into a <script> island unescaped — a name containing
  </script> executed on open. Escape < > & in the injected data and add a CSP
  to the template.
- Second-order injection: citation/identifier fields (source / cwe /
  source_site / correctedSource) were interpolated UNFENCED into the verifier
  prompts that are supposed to be the trust anchor. Fence them in
  extract-rules, harden-scan, uplift-deltas.

uplift design (audit of the new feature):
- Working-copy model: copy the WHOLE solution to modernized/ once and edit in
  place (relative project refs survive; result is a reviewable git diff) —
  the incremental per-project copy broke multi-project builds.
- Dual-run honesty: reframed as 'if both runtimes run here' (net48 needs
  Windows; JUnit/pytest don't multi-target); dummy-test gate now binds a real
  SUT under both targets; per-stack harness notes.
- Tooling honesty: present/runnable/actually-ran distinction; never fold in a
  tool that couldn't run; apiport/2to3 demoted; py2->3 removed from 'preserve'
  examples.
- Delta classes: name the high-blast-radius landmines (JPMS strong
  encapsulation, .NET trimming/AOT, ICU globalization, hosting/runtime-config,
  analyzer/nullable) in the finder briefs + agent.
- Rewrite-vs-uplift signal: weigh by touched sites (siteCount), not delta-card
  count; judgment-share demoted to secondary.

Docs/consistency: brief reads topology.json (not TOPOLOGY.html); README
'five commands'; credential-masking claim split (analysts mask+cite vs
code-writers substitute fakes); read-only/write-scope claims softened to
match enforcement (Bash retained -> discipline, not tool-lock); reimagine
nested blockers/pendingRuleIds; status splits transform vs reimagine markers;
portfolio enumeration basenames; plugin.json description updated.
