test(voyage): empirical jaccard calibration — parked-synthetic placeholders + threshold pin

Step 17 of v4.1 — escalate-handler invoked. Live LLM-budget ($60-120 for 4 plan-runs á /trekplan --profile {economy,premium} on examples/01-add-verbose-flag/brief.md) was not authorized for the v4.1-execute-4b session. Per Step 17 escalate-fallback (and NEXT-SESSION-PROMPT.local.md fallback-strategy): document economy-Plan as parked, use balanced as low-threshold profile, defer empirical calibration to v4.2. Files: tests/synthetic/profile-plan-run-economy-1.md — 30 steps, parked-synthetic tests/synthetic/profile-plan-run-economy-2.md — 30 steps, parked-synthetic tests/synthetic/profile-plan-run-premium-1.md — 40 steps, parked-synthetic tests/synthetic/profile-plan-run-premium-2.md — 40 steps, parked-synthetic tests/synthetic/profile-jaccard-calibration.md — threshold 0.55 pinned per research/02 conservative starting value Replacement procedure documented in calibration.md "How to replace" section. Trigger conditions for empirical re-run: 1. Cross-tier smoke-test (Step 18) flips red on a real run 2. v4.2 LLM-budget approval 3. New profile tier added

+# Cross-tier Jaccard calibration — voyage v4.1
+
+## Status: PARKED-SYNTHETIC
+
+Empirical Jaccard calibration was deferred from v4.1 because the four
+required `/trekplan` invocations cost an estimated $60-120 of LLM-budget
+that was not authorized for the v4.1-execute-4b session. Per Step 17
+escalate-handler, this file documents:
+
+1. The synthetic placeholder fixtures used by Step 18's smoke-test, and
+2. The pinned conservative threshold (`0.55`) from research/02.
+
+## Threshold rationale
+
+`threshold: 0.55` is pinned per research/02 (Recommendation #5):
+
+> "There is no universal Jaccard threshold for cross-model plan
+> agreement. arXiv:2412.12148 reports 0.45–0.65 for n=10 task-pair
+> samples on coding tasks. We recommend a *conservative starting value
+> of 0.55* — this absorbs intra-tier variance and most cross-tier drift,
+> while still flagging severe disagreement (e.g. when one tier produces
+> a fundamentally different decomposition strategy)."
+
+The 0.55 floor is enforced by `tests/integration/profile-jaccard-smoke.test.mjs`
+(Step 18) as a module-local constant `CROSS_TIER_JACCARD_FLOOR`. The test
+also gates on a structural pre-check (step-count parity ±20 % and
+plan-validator strict pass on both fixtures) — these are *non-negotiable*
+even when Jaccard happens to clear 0.55.
+
+## Synthetic fixture pairs
+
+The four parked-synthetic plan-runs in `tests/synthetic/`:
+
+| run-A | run-B | jaccard (synthetic) | normalized |
+|-------|-------|--------------------|-------------|
+| profile-plan-run-economy-1.md | profile-plan-run-premium-1.md | 0.733 | 0.730 |
+| profile-plan-run-economy-1.md | profile-plan-run-premium-2.md | 0.711 | 0.706 |
+| profile-plan-run-economy-2.md | profile-plan-run-premium-1.md | 0.706 | 0.703 |
+| profile-plan-run-economy-2.md | profile-plan-run-premium-2.md | 0.683 | 0.680 |
+
+Min observed (synthetic): 0.680. Min observed minus 0.05 buffer = 0.630.
+We pin `threshold: 0.55` — the lower of (research/02 conservative value)
+vs (min - 0.05 buffer). This is the same rule plan.md Step 17 prescribes:
+`floor(min(jaccard_values), 2) - 0.05` or `0.55`, whichever is lower.
+
+Synthetic Jaccards above are *expected* values for the placeholder
+fixtures; real LLM runs will likely differ. The 0.55 pin remains valid
+across that uncertainty.
+
+## When to replace these fixtures
+
+Trigger empirical calibration when **any** of the following holds:
+
+1. Cross-tier Jaccard smoke-test (Step 18) flips from green to red on a
+   real plan run — indicates the synthetic threshold no longer reflects
+   reality and needs re-grounding.
+2. v4.2 ROADMAP item "empirical Jaccard calibration" is approved and
+   $60-120 LLM-budget is authorized.
+3. A new profile is added (`balanced` already exists; if a fourth tier
+   like `frontier` is added, recalibrate against premium baseline).
+
+## How to replace
+
+1. Run `/trekplan --profile economy --brief examples/01-add-verbose-flag/brief.md`
+   twice. Save each plan's `steps:` frontmatter to
+   `profile-plan-run-economy-{1,2}.md` (overwrite synthetic content).
+   Update `status: parked-synthetic` → `status: empirical`.
+2. Same for `--profile premium`, twice.
+3. Recompute the four cross-tier Jaccards. Update the table above.
+4. Repin threshold: `min(jaccard_values, 2) - 0.05` or 0.55, whichever
+   lower. (Tighter is fine; do not loosen below 0.55.)
+5. Run `tests/integration/profile-jaccard-smoke.test.mjs` — must pass.
+6. Update `empirical_runs: 4`, `synthetic_runs: 0`,
+   `status: empirical`, `ramp_target: stabilized` in this frontmatter.
+
+## Fallback strategy in the meantime
+
+Until real calibration is run, operators are advised to use the
+`balanced` profile (sonnet for most phases, opus for plan + review) as
+the lowest-risk choice. `balanced` was selected as the v4.1 default in
+`commands/trekplan.md` Phase 5.5 specifically to avoid stress-testing
+the cross-tier Jaccard floor with parked-synthetic data.

+# Synthetic plan run economy-1 — Add --verbose flag to CLI (PARKED)
+
+This fixture is a SYNTHETIC PLACEHOLDER for empirical Jaccard calibration
+that requires live LLM-budget ($60-120 for 4 plan-runs). Marked
+`status: parked-synthetic` per the Step 17 escalate-handler in plan.md.
+
+## Why parked
+
+Per NEXT-SESSION-PROMPT.local.md fallback: "Hvis Step 17 LLM-budget
+blokkerer: dokumentér `economy`-Plan som `parked` i kalibrasjons-fil og
+fortsett med Step 18-19 ved bruk av `balanced` som lavterskel-profil."
+
+The session running v4.1-execute-4b did not have authorization for live
+LLM invocation against `/trekplan --profile economy --brief
+examples/01-add-verbose-flag/brief.md`. Synthetic fixtures here represent
+the *shape* of what such a run would produce — fewer total steps (30 vs
+40 in baseline plan-run-A), larger / coarser-grained steps that omit
+sub-verification and benchmark items.
+
+## How this fixture is consumed
+
+`tests/integration/profile-jaccard-smoke.test.mjs` (Step 18) reads the
+`steps` array from the frontmatter and pairs it with the corresponding
+`premium` fixtures to compute cross-tier Jaccard.
+
+When real LLM budget is approved (deferred to v4.2), regenerate this
+fixture by running the actual command and overwriting the frontmatter
+`steps` array. Update `status: parked-synthetic` → `status: empirical`.
+
+## Step-shape rationale
+
+Economy profile uses sonnet for all phases (per
+`lib/profiles/economy.yaml`). Empirical observation from research/02:
+sonnet plans tend toward larger steps, fewer verification entries, and
+fewer edge-case branches than opus plans. The 30 entries here capture the
+typical gist + omit ~10 of the finer-grained items present in opus runs.

+
+# Synthetic plan run economy-2 — Add --verbose flag to CLI (PARKED)
+
+Companion fixture to `profile-plan-run-economy-1.md`. Same `economy`
+profile, simulated as a second run of the same brief, with one step
+replaced (benchmark → timestamp) to model intra-tier variance.
+
+See `profile-plan-run-economy-1.md` for full parked-synthetic rationale.
+
+## Intra-tier Jaccard
+
+Economy-1 vs economy-2 share 29/30 step titles (one differs); union = 31.
+Jaccard = 29/31 ≈ 0.935 — well above any reasonable cross-tier floor.
+This is the expected intra-tier band: small variance because the same
+profile produces near-identical plans modulo language drift.
+
+When real LLM-budget runs replace this synthetic, the empirical
+intra-tier Jaccard is expected to land in the 0.85–0.95 band per
+research/02. Cross-tier (economy vs premium) is the discriminating
+measurement and is documented in `profile-jaccard-calibration.md`.

+# Synthetic plan run premium-1 — Add --verbose flag to CLI (PARKED)
+
+This fixture is a SYNTHETIC PLACEHOLDER for empirical Jaccard calibration
+that requires live LLM-budget ($60-120 for 4 plan-runs). Marked
+`status: parked-synthetic` per the Step 17 escalate-handler.
+
+## Why parked
+
+Same rationale as `profile-plan-run-economy-1.md`. The session running
+v4.1-execute-4b did not have authorization for live LLM invocation. This
+fixture mirrors the existing baseline `plan-run-A.md` (40 steps, opus
+granularity) since premium profile uses opus for `plan` and `review`
+phases per `lib/profiles/premium.yaml`.
+
+## Step-shape rationale
+
+Premium profile uses opus for plan + review phases (per
+`lib/profiles/premium.yaml`). Empirical observation from research/02:
+opus plans tend toward finer-grained steps, more explicit verification
+entries, and richer edge-case decomposition than sonnet plans. The 40
+entries here capture the level of detail typical of an opus run.
+
+## Cross-tier Jaccard pairing
+
+Paired with `profile-plan-run-economy-1.md` and `-economy-2.md` in
+`tests/integration/profile-jaccard-smoke.test.mjs` (Step 18). Expected
+cross-tier Jaccard for the parked-synthetic run-pair is documented in
+`profile-jaccard-calibration.md`.

+# Synthetic plan run premium-2 — Add --verbose flag to CLI (PARKED)
+
+Companion to `profile-plan-run-premium-1.md`. Same `premium` profile,
+simulated as a second run with two terminal steps replaced
+(emission cost / benchmark methodology → capture overhead / overhead
+methodology) to model intra-tier variance.
+
+## Intra-tier Jaccard
+
+Premium-1 vs premium-2 share 38/40 step titles; union = 42.
+Jaccard = 38/42 ≈ 0.905 — matches the existing baseline plan-run-A vs
+plan-run-B floor (≥ 0.833 in plan-determinism.test.mjs).
+
+## Cross-tier Jaccard rationale
+
+Pairing premium fixtures (40 steps) against economy fixtures (30 steps)
+yields ~30 shared titles (after string-normalisering), with union ~40.
+Conservative cross-tier Jaccard ≈ 30/40 = 0.75 in this synthetic — but
+the calibration file pins a *more conservative* floor (0.55) per
+research/02 to absorb empirical variance once real runs replace these
+fixtures. See `profile-jaccard-calibration.md` for threshold derivation.
