Patton's request, KI7MT-approved. Six existing briefs (~20 lines each)
expanded to ~80-120 lines using a consistent seven-section skeleton.
New seventh role failure-analyst added.

Skeleton (every brief)
  1. One-paragraph role + disposition
  2. Strengths     concrete capabilities, not adjectives
  3. Avoids        what the agent declines, even if asked
  4. Inputs        what to send, in what format
  5. Outputs       what to expect back, in what shape
  6. Hand-offs     who receives output and what they need
  7. When to use   right time vs wrong time

Brief line counts (before -> after)
  architect.md         20 -> 91
  implementer.md       20 -> 87
  operator.md          18 -> 97
  ops.md               19 -> 96
  reviewer.md          22 -> 88
  tester.md            20 -> 96
  failure-analyst.md    0 -> 115  (new)
  total               119 -> 670

Why a failure-analyst slot

Distinct from reviewer (reviewer reads diffs and reports; failure-
analyst writes throwaway probes to falsify claims, then reports what
survived) and from tester (tester writes coverage; failure-analyst
writes attacks). The combination - does not write production code,
writes adversarial tests, owns the failure-mode taxonomy - was not
captured in any of the six existing briefs.

examples/README.md
  Rewritten to introduce the seven roles, include an ASCII pipeline
  diagram, document the seven-section skeleton, and walk through
  copying the bundle into the runtime briefs directory.

README.md (root)
  One-paragraph pointer at the brief-format section directing readers
  to examples/briefs/ and examples/README.md. Closes the
  discoverability gap Patton flagged.

Pending: Watson voice review before merge (Patton's explicit ask).
Tests + lint still clean (159 Python + 7 Go, ruff + golangci-lint
both 0 issues). No code changes - content only.
