+## Results (2026-07-04 — experiment complete, 5 iterations)
 
-- 2026-07-04: hypotheses locked, experiment starting (baseline commit cc-os `c645faa`).
-  Results to be appended here per iteration.
+Final full grid: **sonnet 8/8** (was 5/8), **haiku 7/8** (was 0/8; the one miss is a W3
+axis-b judge-boundary flicker — it consulted, and passed the same cell in the mid-experiment confirmation). Per-iteration:
+
+1. **Iter 1 — trigger-conditioned rewrite, all channels** (hook note, find/create
+   descriptions + bodies, fixture CLAUDE.md): R1/sonnet FAIL→3/3 PASS; haiku W2 canary
+   0→3/3 PASS; W3/sonnet 1/3 (axis-b persists); W1 control holds. **H1 CONFIRMED** — and it reaches haiku, so haiku's 0/8 was packaging, not a capability floor.
+2. **Iter 2 — "task not complete until superseding ADR exists"**: W3 still 1/3. Transcript
+   analysis showed the model behaving *well* (catches the conflict, offers options with the
+   ADR attached to the reversal path) but phrasing the offer conditionally inside an option
+   list — judge flicker at the rubric boundary, not forgetting.
+3. **Iter 3 — explicit-unconditional recording offer** ("state plainly: this reverses
+   ADR-NNNN; I'll record a superseding ADR — never a parenthetical in an option list"):
+   W3/sonnet 3/3 PASS. **H3 CONFIRMED** (placement in the find skill's act-on-findings step,
+   where find's output is on screen).
+4. **Iter 4 — lower threshold "modifying existing behavior → find first"**: R4/haiku 0→3/3;
+   R1/haiku still 0/3. Transcript: haiku classified R1's task as a *pure addition* (new
+   bypass method), so any semantic trigger missed it.
+5. **Iter 5 — fully mechanical trigger** ("before your first edit to any existing file →
+   run find on those paths; additions count — a new method can bypass a decided
+   constraint"): R1/haiku axis-a 3/3, full 2/3; R2 distractor control holds (no
+   over-triggering); sonnet unaffected.
+
+**Verdicts:** H1 confirmed (trigger-conditioned ≫ inventory phrasing, both tiers). H3
+confirmed (each rule lives where its precondition is visible; step-2 wording in the find
+skill fixed W3). **H2 NOT tested** — channels were never ablated (all-on throughout); whether
+the SessionStart hook is redundant next to a trigger-phrased CLAUDE.md remains open. Also
+open: R4-nograph now PASSES on both tiers — the strengthened wording made the graph layer
+unnecessary for that scenario, so the degradation check no longer differentiates.
+
+**Tier-generalization lesson:** each tier down needs a more *mechanical* trigger. Sonnet
+acts on "architecture-level choice"; haiku needs "before editing any existing file, run
+find — additions count." The mechanical rule subsumes the semantic one and costs one cheap
+deterministic CLI call per task — lead with it in future packaging.
+
+**Deployment note:** the fixture CLAUDE.md section is the template for real-project
+adoption (candidate: emit it from `/os-adr:init`/`migrate`); winning wording committed to
+cc-os (hook `session_start.py`, find/create SKILL.mds, eval-b fixture CLAUDE.md).
