The .tmpl split-mirror (PR #1, commit 789d4ca) moved the validation-log
sections out of the 6 gstack SKILL.md bodies and added pointers to
references/validation-log.md, but did NOT carry the reference files
themselves. The pointers became orphans and the audit content was
effectively lost on the durable LexClaw/gstack fork (fresh installs /
gstack-upgrade would ship dead pointers).

Restores the 6 references/validation-log.md files from the original
local fix commit 9b937ba so acceptance garrytan#4 (validation logs readable
via references/, no content lost) holds:
  ship 7521, plan-ceo-review 8156, office-hours 2709,
  plan-design-review 17158, plan-devex-review 16178, design-review 1588

Verified: bun run gen:skill-docs is a no-op on tracked SKILL.md
(references are not gen inputs); all 6 target SKILL.md bodies stay
under the 100k Hermes freeze wall after regen.

Upstream-Candidate: no

Consolidates the three stranded card-related commits on lexclaw/main into
one coherent deliverable so a routine bun run gen:skill-docs cannot
re-freeze the 6 split gstack skills over the 100k Hermes size gate:

- .tmpl split-mirror (from 789d4ca, PR #1): templates carry the
  validation-log pointer; canonical SKILL.md regenerates under 100k.
- restored 6 references/validation-log.md files (from 80d14cb): PR #1
  left orphan pointers to missing reference files; restored so no
  audit content is lost on the durable fork.

Verified: bun run gen:skill-docs is a clean no-op on tracked SKILL.md
(reference files are not gen inputs). Post-regen sizes: ship 91966,
plan-ceo-review 92178, office-hours 96444, plan-design-review 91412,
plan-devex-review 90598, design-review 94330. Zero of the 6 targets
>=100k. office-hours is 1444 over the 95k soft target but 3556 under
the 100k freeze wall; its remaining body is irreducible core workflow,
so forcing it under 95k would extract a runtime phase. Judgment: hold
at 96444, AC3 (the load-bearing gate) fully met.

Upstream-Candidate: no
