## Problem
Claude **subscription** (Max/Pro) chats fail with a rotating `404 / 502
/ 429` cascade — the same symptom as #1857, which was reported fixed.
Raw `ANTHROPIC_API_KEY` and explicit Claude CLI usage work; direct OAuth
does not.
## Root cause (proven against git history)
- **v0.51.0 (worked):** `packages/core/src/anthropic-models.ts` didn't
exist. `getApiKey("anthropic")` returned the subscription **OAuth**
access token and pi-ai's built-in `anthropic` provider POSTed it to
`api.anthropic.com/v1` with **Claude Code identity headers** (`Bearer` +
`anthropic-beta: claude-code-20250219,oauth-2025-04-20`). Direct OAuth
worked — **not** via the CLI.
- **The regression chain:** #1857 mis-concluded "0.51.0 uses the CLI /
OAuth is blocked on /v1" (its `grep` missed the runtime-appended `/v1`;
a naive curl repro lacked pi-ai's full impersonation). FN-7291 → FN-7391
→ FN-7396 were built on that wrong premise. FN-7396's
`registerAnthropicSubscriptionProvider` rerouted subscription OAuth to a
new `anthropic-subscription` provider **still pointed at
`api.anthropic.com/v1`** — reintroducing #1857.
## Fix — restore the v0.51.0 path (three independent surfaces, no
rerouting)
- **`auth-storage.ts`** — `getApiKey("anthropic")` resolves
subscription/legacy OAuth again (raw API key still takes precedence), so
the built-in provider receives the token.
- **`pi.ts`** — remove the runtime reroute and the `/v1`-based
`anthropic-subscription` execution provider; `anthropic/*` selections
stay on the built-in OAuth-capable provider.
- **`register-model-routes.ts`** — advertise `anthropic` in the picker
for OAuth users so direct OAuth is selectable.
- Result: **direct OAuth**, **raw `ANTHROPIC_API_KEY`** (precedence),
and **explicit `pi-claude-cli`** all work independently.
## Verification
- `packages/engine`: `auth-storage.test.ts` +
`pi-create-fn-agent.test.ts` — **137 passed** (assertions restored to
the correct invariant; the FN-7391/FN-7396 tests encoded the bug).
- `packages/dashboard`: `routes-auth.test.ts` + `usage.test.ts` — **352
passed**.
- `pnpm --filter @fusion/engine build` clean.
- Docs (`settings-reference.md`, `dashboard-guide.md`) + changeset
updated.

The vendored pi-claude-cli extension declared `@earendil-works/pi-ai` and
`pi-coding-agent` as `*` peers, so its dev/workspace resolution drifted to
0.77.0 while the rest of the workspace is on ^0.80.3. Pin both peers to
^0.80.3 so the extension's `getModels("anthropic")` catalog (which feeds the
pi-claude-cli picker rows) matches the engine/cli — 0.80.3 ships
claude-sonnet-5 natively. Behavior-preserving; the bundled CLI already
provided 0.80.3 at runtime.

Sonnet 5 had disappeared from every surface: pi-ai 0.79.9 (the installed
version) lacks it, and FN-7374 removed the static row expecting the live
registry to carry it. Live-verified that claude-sonnet-5 returns 200 on
api.anthropic.com/v1 with a raw ANTHROPIC_API_KEY and runs via the Claude
CLI (it 403s on subscription-OAuth /v1 — scope-gated; runtime fallback
applies). Note: pi-ai 0.80.3 ships sonnet-5 natively, so this SUPPLEMENTAL
row dedupes once the install catches up.
- core: re-add claude-sonnet-5 to SUPPLEMENTAL_ANTHROPIC_PROVIDER_REGISTRATION
and restore its static pricing (revert FN-7374); update pricing tests.
- engine/dashboard tests: flip the FN-7374 "withheld" assertions to the
restored "advertised" behavior.
PR feedback:
- Trim the two FNXC comments (auth-storage.ts, pi.ts) to concise
requirement prose per coding guidelines (CodeRabbit).
- Replace the now-inert getApiKey mock in two subscription routing tests
with a clarifying note (Greptile).

Claude subscription (Max/Pro) chats regressed to 404/502/429 because
FN-7396 rerouted subscription OAuth to a /v1-based `anthropic-subscription`
runtime provider — reintroducing issue #1857 that FN-7391 had fixed. Both
routed the OAuth token to api.anthropic.com/v1, the surface that broke.
Proven in code that v0.51.0 (working) sent subscription OAuth directly to
/v1 via pi-ai's built-in `anthropic` provider (Claude Code impersonation:
Bearer + anthropic-beta oauth headers), NOT through the CLI. Restore that:
- auth-storage: getApiKey("anthropic") resolves subscription/legacy OAuth
again (raw API key still wins), so the built-in provider gets the token.
- pi.ts: remove the runtime reroute and the /v1 `anthropic-subscription`
execution provider so anthropic/* selections stay on the built-in provider.
- register-model-routes: advertise `anthropic` for OAuth users so direct
OAuth is selectable in the picker.
Three independent surfaces, no rerouting: direct OAuth, raw ANTHROPIC_API_KEY
(precedence), and explicit pi-claude-cli.
Fixes#1857

## Summary
- add an opt-in `allowAnswerQuestionIdDrift` flag for interactive AI
sessions
- keep strict question-id validation by default
- enable the tolerance only for Compound Engineering recovered sessions
so persisted session rows can answer after dashboard
restarts/non-deterministic rehydration
## Test Plan
- `corepack pnpm --filter @fusion/engine exec vitest run
src/__tests__/interactive-ai-session.test.ts --silent=passed-only
--reporter=dot`
- `corepack pnpm --filter @fusion/engine typecheck`
- `corepack pnpm --filter @fusion-plugin-examples/compound-engineering
build`

## Summary by CodeRabbit
* **Bug Fixes**
* Improved interactive session recovery so persisted answers can
continue after dashboard restarts, even if the question ID changes
during rehydration.
* Keeps strict question-ID validation by default; mismatches still fail
unless drift is explicitly allowed.
* **New Features**
* Added `allowAnswerQuestionIdDrift` option to permit accepting the
persisted question ID during recovered session answering.
* **Tests**
* Added/updated coverage for strict mismatch error behavior and the
successful completion path when drift is enabled.

The step execution engine was already gone (runWorkflowSteps deleted,
workflow_steps table dropped in migration 132). This removes what remained:
the linear step compiler (compileWorkflowToSteps/validateLinearity/
WorkflowCompileError), which survived only as a validator + step-preview
generator.
parseWorkflowIr/validateV2 (which accepts branching graphs) is now the sole
workflow validity gate at save/select/refine and in the graph task runner.
Custom branching workflows are now selectable and run on the graph
interpreter instead of being rejected as non-linear.
- core: delete workflow-compiler.ts; rework store.validateWorkflowCompilable
onto parseWorkflowIr; move MERGE_REGION_NODE_KINDS into
workflow-lifecycle-validation; retag workflow-steps-to-ir as legacy lowering
- engine: drop the compiler double-validation in workflow-graph-task-runner
- dashboard: remove POST /api/workflows/:id/compile + client wrapper; drop the
interpreterOnly response field and editor banner; no post-save compile check
- i18n: remove the orphaned workflowNodes.interpreterOnly key across locales
- tests: reframe two workflow-selection tests whose premise inverted; fix a
pre-existing red in builtin-lead-generation (completion-summary node)

Task context menus now place destructive actions after safer task operations.
- Reorder shared task action descriptors so Reset and Delete render at the bottom, with Delete last.
- Update context-menu model coverage for lifecycle, GitHub tracking, pause, and workflow column states.

Auto-merge finalization now ignores stale branch-only residue once durable merge proof exists, so squash-landed tasks do not stay stuck in review because their task branch history is noisy.
Fusion-Task-Id: FN-7360
Pin fresh task worktree creation to the resolved integration branch when no explicit executionStartBranch is present, so ambient root checkout state cannot leak sibling task commits into new branches.
Use task baseCommitSha for merge-finalization branch proof when available, allowing already-landed mergeConfirmed tasks to finalize even if historical branch ancestry contains foreign commits.
