+# Calibration SubAgent Skill
+
+## Goal
+
+For the **current TOC region**, discover page-numbering **regimes** and an
+**initial offset** for each regime that has usable entries. Submit candidate
+offsets via `calibration.submit`. After submit, a deterministic completion pass
+runs the production tail-verify → binary-search → small-step recalibrate loop
+(using the same visual page confirmer as production). Only **complete segments**
+are usable for coarse structure; unrecognized pages are treated as **no TOC**.
+
+## Do not use
+
+- Do not scan a fixed window after the TOC (the old “TOC end + N pages” probe).
+- Do not invent physical pages you did not inspect or obtain from `link`.
+- Do not track a total page-count budget. Limits are **token budgets** and
+  **max_rounds** in the payload. A per-call page cap is only a batch-size limit.
+
+## Mandatory first step — partition regimes
+
+Inspect every `page_number` label on the current TOC entries and partition them
+into **page-numbering regimes** (distinct numbering systems / label shapes:
+decimal digits, roman numerals, prefixed folio labels, etc.).
+
+- Do not mix samples across regimes when computing an offset.
+- Include `entry_indices` (0-based indices into `toc_region.entries`) for each
+  regime you submit.
+- Run the same initial-calibration procedure independently for each regime that
+  has usable entries.
+
+## Phase 1 — Initial offset (your job via tools)
+
+For each regime:
+
+1. Select a small set of entries (prefer spread: early / middle / late when
+   enough entries exist).
+2. Candidate physical page:
+   - If the entry has `link.physical_page`, use it as the primary candidate.
+   - Otherwise derive a coarse physical candidate from the printed label and
+     `page_count`, then confirm with vision.
+3. Progressive `inspect.pages` for that title (start small, expand only if needed):
+   - **1st call**: inspect **1** candidate page only.
+   - **2nd call** (if miss): inspect up to **3** nearby pages.
+   - **3rd call** (if still miss): inspect up to **5** nearby pages.
+   Never open with a full 5-page batch when a single page has not been tried.
+4. Compute `offset = physical - printed` using this regime’s interpretation of
+   the printed label.
+5. Submit **candidate** offsets. Do not treat Phase 1 alone as a finished
+   coarse-structure calibration.
+
+If `inspect.pages` returns budget exhausted, or rounds run out before a reliable
+offset: treat that sample / regime as **not found**, submit whatever regimes you
+already confirmed (or `status=failed`), and let production fallback handle the
+rest. Do not guess pages.
+
+## Phase 2 — Completion (deterministic after submit; production path)
+
+For each TOC region, every regime with a candidate offset is completed
+independently, then merged by **physical page**:
+
+1. Build TitleNodes via production `extract_toc_nodes` (regime-aware parse:
+   decimal / roman / prefixed labels → `printed_page` + `page_kind`).
+2. For **each** regime with an offset:
+   - Project leaves belonging to that regime
+   - Run production Phase-2: prune → tail verify → binary-search →
+     small-step recalibrate (single-leaf regimes apply offset directly)
+3. Merge all regime `match_overrides` (physical pages), then null-page parent
+   locate once on the combined tree.
+4. Emit production `SkeletonAnchor` (`offset` = primary decimal summary,
+   `match_overrides` = union of all regimes, `null_page_report`, `bulk_count`,
+   `pruned_count`, `locate_agent`).
+5. On recalibrate/budget failure inside one regime: keep that regime's complete
+   **prefix**; **drop** unresolved **suffix** leaves from the TOC tree (no TOC),
+   then run null-page parent locate on what remains. Never fall back to a fixed
+   post-TOC window.
+
+## Usability bar
+
+- Coarse structure may use the result when `SkeletonAnchor.offset_status=ok`
+  and `bulk_count > 0` (at least one complete production segment).
+- Otherwise downstream treats the document as no-TOC / Root fallback.
+
+## Tools
+
+- `inspect.pages`: primary tool for Phase 1. Open physical pages, render, answer
+  your question. Prefer the progressive 1→3→5 schedule above. Per-call page
+  count is capped; overall spend is limited by the calibration visual token
+  budget and `max_rounds`.
+- `calibration.submit`: finish Phase 1. Pass the full result under
+  `tool_args.result` (or result fields directly in `tool_args`).
+
+## Output rules
+
+- Submit `status`, `regimes`, top-level `offset` / `offset_status` for the
+  primary decimal-digit regime when identifiable, `tool_calls`, `notes`.
+- Each regime must include `kind`, candidate `offset`, `offset_status`,
+  `entry_indices`, `samples` (with `title`, `printed_label`, `physical` when
+  known), and `posterior` if you already inspected a late check.
+- Keep `kind` values consistent within one run (`decimal`, `roman`, `prefixed`,
+  or `other`).
+- Stay within the token / round budgets announced in the payload.
