Builds the false-positive/true-positive proof the plan requires before the guard can be
promoted to blocking, and fixes the one false-positive it surfaced.
- test-harness-guard.sh: 12-case matrix in a throwaway repo, runs the REAL guard, asserts
WARN/clean for real conflicts/secrets/keys vs legit content (setext underlines, dividers,
docs that mention a marker, encrypted sops, public keys, .example templates).
- harness-guard.sh: conflict rule now requires a real hunk (BOTH ^<<<<<<< AND ^>>>>>>>),
dropping the lone =======$ trigger that false-positived on a 7-char setext underline /
divider. Identical true-positive power (git writes all three markers); FP surface -> 0.
- /self-check: new harness.guard_selftest runs the matrix in an isolated temp repo (read-only
vs the real tree) so guard correctness is continuously proven.
Verified 12/12 pass, true positives intact, real-tree FP surface = 0. FATAL flip (todo
f1c11d0d, on/after 2026-06-22) is now evidence-backed + one-step.

Adds a 'harness' category to /self-check (Task 12, self-check half) so the harness-
optimization gains can't silently regress. All read-only / non-invasive:
- VERSION marker present + not older than manifest.harness.min_version
- skill-registry description budget (sum of all SKILL.md description: fields under
registry_desc_budget_chars) -- the metric that catches Task 5 bloating back
- global deploy targets ~/.claude/skills + ~/.claude/commands populated (Mac-wipe failure)
- harness-guard.sh present + wired into sync.sh
- core scripts parse (bash -n on sync/guard/now-phoenix); now-phoenix.sh emits a valid date
Tunables in baseline/manifest.json 'harness' block. Verified 9/9 PASS; budget WARN
negative-tested at a synthetic over-budget value.

Task 3/3a of the harness-optimization spec. Mike confirmed normal billing uses
add_line_item; timers stay available only for explicit outlier requests, never the
normal loop. Rewrote time-entry-protocol.md to defer to the /syncro command (SSOT for
billing mechanics) and state timers are outlier-only; aligned the command's two
absolute "no timers" lines. Contradiction removed.

Optimize the harness (not projects) for accuracy/completeness with context pressure
as a first-class constraint; token efficiency secondary. Authored as a Claude+Grok+
Gemini review (see review-3way.md): P0 reliability footguns (submodule-safe sync,
serialized/staged wiki synthesis, syncro SSOT, warn-only guard), P1 context diet
(one-line registry descriptions, CLAUDE CORE/EXTENDED, thin save/sync), P2 delegation
re-tune, P3 knowledge tiering. Adds harness VERSION marker + OOB recovery as rollout
safety. Python port split to a separate future spec.
