- FallbackResolver.setUnitContext() stores {unitType,unitId} from autonomous dispatch
- run-unit.js calls pi.setFallbackUnitContext() before/after each unit
- _findAnyAvailableFallback uses real unitType/unitId from context, not sentinel
- Schema v59: failure_mode column in llm_task_outcomes
- insertLlmTaskOutcome accepts failure_mode (rate_limit, quota_exhausted, auth_error)
- register-hooks.js passes event.classification.reason as failure_mode
- register-hooks.js uses real event.unitId when available
- ExtensionRuntimeActions.setFallbackUnitContext added to pi API surface

When a model fails and FallbackResolver picks a replacement, it now:
1. Fires the before_model_select hook with reason='fallback' and the
failing model's ID — the learning system records the failure outcome
and returns the best Bayesian-blended replacement from llm_task_outcomes
2. Falls back to the existing heuristic sort (reasoning + context window)
if the hook is unavailable or returns no override
Changes:
- BeforeModelSelectEvent: add optional currentModelId and reason fields
- FallbackResolver: accept emitBeforeModelSelect in constructor; make
_findAnyAvailableFallback async; fire hook before heuristic fallback
- agent-session.ts: inject lazy emitBeforeModelSelect closure into resolver
- register-hooks.js: record failure outcome when reason='fallback' before
returning selectLearnedModel result

- Add packages/coding-agent/src/utils/format.ts as the canonical source
for formatDuration, formatTokenCount, truncateWithEllipsis, sparkline,
formatDateShort, fileLink, stripAnsi, normalizeStringArray — all already
exported from @singularity-forge/coding-agent via index.ts.
- Convert shared/format-utils.js to a compatibility shim that re-exports
the 8 functions from @singularity-forge/coding-agent. All 13 importers
continue to work with no import changes required.
- Convert shared/path-display.js to a compatibility shim that re-exports
toPosixPath from @singularity-forge/coding-agent. Implementation in
packages/coding-agent/src/utils/path-display.ts was already canonical.
- shared/frontmatter.js is intentionally NOT shimmed: splitFrontmatter/
parseFrontmatterMap have a different API from the package's parseFrontmatter/
stripFrontmatter (flat-map vs {frontmatter, body} object).

- Create packages/coding-agent/src/core/providers/web-search-middleware.ts with
WebSearchMiddleware class: injects web_search tool, enforces session budget (#1309),
strips thinking blocks from history, and respects PREFERENCES.md search_provider.
- Wire webSearchMiddleware.applyToPayload into sdk.ts onPayload callback (before
extension hook dispatch) so injection runs as compiled TypeScript with zero
jiti-dispatch overhead.
- Export WebSearchMiddleware, webSearchMiddleware singleton, setPreferBraveResolver,
CUSTOM_SEARCH_TOOL_NAMES, MAX_NATIVE_SEARCHES_PER_SESSION, and stripThinkingFromHistory
from @singularity-forge/coding-agent so the extension can delegate to the same instance.
- Refactor search-the-web/native-search.js: remove self-contained injection logic;
import and delegate before_provider_request to webSearchMiddleware singleton.
Use tri-state isAnthropicProvider (null/false/true) to synthesize a provider hint
when event.model is absent but model_select has already fired — prevents the
model-name heuristic from wrongly injecting into Copilot claude-* requests.

- Delete memory-backfill.js — not imported anywhere, dead code
- Rename memory-sleeper.js → tool-watchdog.js — misnamed; it is a
tool-output watchdog with no relation to the memory store
- Collapse memory-embeddings-llm-gateway.js into memory-embeddings.js —
removes the lazy-import split; loadGatewayConfigFromEnv,
createGatewayEmbedFn, and rerankCandidates are now direct exports
- Remove buildEmbeddingFn() dead stub (always returned null)
- Enable packages/coding-agent memory extraction extension by default
(memory.enabled ?? true) so session-level extraction is active
- Update all import sites and tests
