+# Semantic Catalog Reconciliation
+
+**Document status:** Canonical reconciliation ledger (PAP-17025)<br>
+**Date:** 2026-08-11<br>
+**Authority:** `src/catalog/reconciliation.ts` (machine-readable), drift-checked by `src/catalog/reconciliation.test.ts` and `src/catalog/catalog-docs.test.ts`.<br>
+**Parent plan:** Runner foundation review plan (PAP-17016), deliverable D and execution step 1.
+
+## Purpose
+
+The runner carried two independently hand-maintained semantic catalogs. This is
+the first reconciliation gate of the foundation plan: establish one
+machine-readable authority over both, name every operation's full metadata, and
+record every divergence with an explicit disposition so no specification calls
+either catalog canonical and no stale count or unreviewed divergence can land.
+
+## The two catalogs
+
+| Catalog | Module | Count | Descriptor | Consumers |
+| --- | --- | --- | --- | --- |
+| Scenario / eval | `src/tools/` | 37 (14 always + 23 optional) | Rich: placement (`disposition`), `sideEffectClass`, `idempotency`, `redaction`, `mockCommandMapping` | `src/scenarios/*`, `src/conformance/*`; package-root default export |
+| Live runtime | `src/semantic-tools/` | 28 (13 always + 15 optional) | Live: `exposure`, `allowedModes`, `disabledByDefault`, provider input/output schemas; runtime dispatcher + policy + redaction | `src/live/*` (live Codex), `src/issue-thread/*`, generated `semantic-tool-contracts.json`; package-root `acceptedCapabilitySemanticTools` |
+
+Reconciled op-set relationship (pinned by the drift test):
+
+- **24 shared** operation ids.
+- **13 scenario-only:** `administer_company`, `export_company`, `inspect_operation_result`, `list_cases`, `list_company_skills`, `list_goals`, `list_projects`, `list_routines`, `list_secret_metadata`, `manage_routine`, `read_secret_value`, `sync_company_skills`, `upsert_case`.
+- **4 live-only:** `get_agent`, `get_approval`, `get_approval_context`, `schedule_wake`.
+- **Union = 41 operations.**
+
+## Canonical authority decision
+
+- **Descriptor schema:** the rich `src/tools/` descriptor is the canonical shape.
+  It is the only one that already names placement, side-effect class,
+  idempotency, redaction, and mock mapping — the per-operation facts the plan
+  requires. The canonical authority extends it with **real-binding status** and
+  **PRP-evidence shape**.
+- **Machine-readable authority:** `src/catalog/reconciliation.ts` enumerates the
+  41-op union exactly once (`CAPABILITY_CANONICAL_CATALOG`), each entry naming
+  placement, claims, task modes, roles, side-effect class, idempotency,
+  redaction, mock mapping, real-binding status, PRP evidence, and legacy
+  aliases. `capabilityCatalogReconciliation()` computes the op-set summary and
+  the divergence ledger.
+- No spec should call either `src/tools/` or `src/semantic-tools/` canonical.
+  Both remain in place this increment; the follow-on collapses them into
+  derivations of the authority.
+
+## Real-binding status (before real Paperclip service binding)
+
+No operation is bound to a real Paperclip service yet; the deterministic mock is
+the only backend (real-service binding is deliverable G). Each operation's
+current executability is classified as:
+
+- **`live_codex` (27):** executed by the live dispatcher against the mock and
+  exposed to live Codex — the 24 shared ops (minus the test-only escape hatch)
+  plus the 4 live-only ops.
+- **`scenario_mock` (13):** defined only in the scenario/eval catalog and driven
+  through the scenario runtime / mock extensions; no live dispatcher binding.
+- **`test_only` (1):** `generic_api_request` — the escape hatch, which by rule
+  **cannot count as product capability coverage**.
+
+## Divergence ledger
+
+For every shared operation the authority compares `requiredClaims`, task modes,
+and input-schema shape, and records a disposition. The drift test fails if a new
+divergence appears without one.
+
+- **Claims (1):** `generic_api_request` requires `test:generic_api` (scenario)
+  vs `test:generic_api_request` (live). Same reviewed test-only grant; unify in
+  the follow-on.
+- **Task modes (15):** `block_task`, `comment_on_approval`,
+  `control_workspace_service`, `create_task`, `decide_approval`, `finish_task`,
+  `get_workspace_runtime`, `list_agents`, `list_approvals`,
+  `register_deliverable`, `report_progress`, `request_approval`,
+  `request_review`, `search_tasks`, `set_dependencies`. The scenario catalog
+  scopes modes to the coverage the suite drives (adds `skill_test`, restricts
+  optional reads to `standard`); the live catalog encodes the runtime exposure
+  policy (opens optional reads to `ask`/`planning`, keeps terminal writes
+  `standard`-only). Reconcile to one canonical policy in the follow-on.
+- **Input-schema shape (shared mutations and some reads):** the scenario
+  descriptor keeps idempotency out-of-band and omits provider bounds; the live
+  provider descriptor threads `idempotencyKey` in-band and adds length/pattern
+  bounds for the model. Unify the schema in the follow-on.
+
+## Legacy MCP aliases
+
+Legacy MCP aliases are indexed in `spec/capability/mcp-tool-map.yaml`
+(`inventoryRole: legacy_alias_index`, generated from `packages/mcp-server`). Each
+alias row carries a `foldedInto` disposition linking it to the native eval/
+operation that now covers its behavior; the reconciliation drift test asserts
+every row has one. The authority additionally records the direct native
+operation for the well-known aliases (for example `paperclipListAgents` →
+`list_agents`, `paperclipGetAgent` → `get_agent`, `paperclipListIssues` →
+`search_tasks`, `paperclipCreateIssue` → `create_task`).
+
+## Deliberate decisions recorded for the surface-ledger and eval tasks
+
+This increment makes **no runtime behavior change** — both catalogs keep their
+exact current surfaces, so the live golden and scenario suites are unchanged.
+The reconciliation records the following decisions to be executed by the
+schema-migration follow-on and consumed by the real-surface-ledger (deliverable
+B) and eval (deliverable F) tasks:
+
+1. Collapse `src/tools/` and `src/semantic-tools/` catalog lists into
+   derivations of `src/catalog/reconciliation.ts`, so there is one source of
+   truth and the second module is compatibility-only.
+2. Unify the `generic_api_request` claim to a single test-only grant.
+3. Choose one canonical task-mode policy per operation (the ledger's 15 task-mode
+   divergences).
+4. Unify the input-schema shape (idempotency handling and provider bounds) —
+   this changes the live provider schemas the model sees and the generated
+   `semantic-tool-contracts.json` golden, and therefore requires live/browser
+   re-QA.
+5. Decide the placement of the 13 scenario-only and 4 live-only operations on the
+   unified surface (which become always/optional, which stay scenario/eval-only,
+   which gain a live binding).
+
+## Verification
+
+- `src/catalog/reconciliation.test.ts` — pins the op-set relationship, requires a
+  reconciliation entry and full metadata for every union operation, classifies
+  real-binding status, and requires a disposition for every divergence.
+- `src/catalog/catalog-docs.test.ts` — recomputes the catalog counts and
+  membership in `docs/capability-semantic-tools.md` from the catalog so a stale
+  hand count fails.
