+# Decision
+
+## Option A
+Update `isRunArgsForMode` in `web/runner/messages.js` to correctly accept `inputs` (in-memory file arrays), `paths` (string arrays), or `scan` objects as valid run arguments, according to the memory guideline: "In the `tokmd` `web/runner`, run message arguments can be passed via `inputs` (in-memory file arrays), `paths` (string arrays), or `scan` objects. Validation logic (e.g., `isRunMessage`) must accept payloads utilizing any of these valid structures, not strictly requiring `inputs` in all cases." Also update `messages.test.mjs` to reflect this change.
+
+## Option B
+Do not fix `web/runner/messages.js` but create a learning PR documenting the friction.
+
+## Decision
+Choose Option A to fix the missing drift between expected run message capabilities and the implemented `web/runner` verification.

+## 💡 Summary
+Aligned web runner validation logic with the capabilities supported by tokmd core. The runtime now properly accepts run payloads that utilize `inputs`, `paths`, or `scan` objects instead of artificially restricting them strictly to `inputs`.
+
+## 🎯 Why
+According to system memory and cross-surface capabilities: "In the `tokmd` `web/runner`, run message arguments can be passed via `inputs` (in-memory file arrays), `paths` (string arrays), or `scan` objects." However, `messages.js` explicitly required only `inputs` arrays, causing valid configuration drifts between what the backend could handle and what the runner verified.
+
+## 🔎 Evidence
+File path: `web/runner/messages.js`
+Observed: `isRunArgsForMode` hard-enforced `inputs` and returned false for `paths` or `scan`.
+
+## 🧭 Options considered
+### Option A (recommended)
+- Support checking whether valid payloads such as `inputs`, `paths`, or `scan` options are present in the `hasValidPayloadType` capability before rejecting them in `isRunArgsForMode`.
+- Fits the repo and shard since this resolves a structural gap between Rust expectations and runner parsing.
+- Trade-offs: Increases complexity slightly in Javascript validation, but unlocks accurate usage patterns.
+
+### Option B
+- Record friction item but make no changes to runner logic.
+- When to choose: If adding support in WASM/Javascript causes breaking changes.
+- Trade-offs: Maintains the cross-surface drift without unlocking real paths/scan support.
+
+## ✅ Decision
+Chose Option A to eliminate the drift and correctly authorize `inputs`, `paths`, or `scan` in standard JS payloads, aligning `messages.js` with the stated runtime capabilities.
+
+## 🧱 Changes made (SRP)
+- `web/runner/messages.js`: Updated `isRunArgsForMode`, `hasValidPayloadType`, and `isScanOptions` to support the multiple payload properties.
+- `web/runner/messages.test.mjs`: Adjusted assertions to expect `true` for messages that send `paths` and `scan`.
+
+## 🧪 Verification receipts
+```text
+> test
+> node --test ./*.test.mjs
+
+...
+# tests 45
+# suites 0
+# pass 44
+# fail 0
+# cancelled 0
+# skipped 1
+# todo 0
+```
+
+## 🧭 Telemetry
+- Change shape: Structural / Capability Enablement
+- Blast radius: `web/runner` compatibility alignment
+- Risk class: Low, loosens artificial payload restriction cleanly
+- Rollback: Revert to require strictly `inputs`.
+- Gates run: `npm test --prefix web/runner`
