IHUB-WP-0017 — Autonomous Error-Fix Loop: Reach Clean Build

Goal

Drive the inter-hub codebase to a clean ghcid build ("All good, N modules loaded") by fixing compilation errors bottom-up, one module at a time.

Pre-conditions

• Must be run inside devenv shell (IHP_LIB must be set, ghcid in PATH)
• WP-0016 complete (compile-check scripts and ghci flags in place)

How to start

# Enter devenv shell first:
devenv shell

# Then start this loop:
/ralph-workplan workplans/IHUB-WP-0017-error-fix-loop.md

Error-Fix SOP (Standard Operating Procedure)

1. Run: scripts/compile-check --bg
2. Tail /tmp/ihub-compile-errors.txt
3. Parse errors: group by module, order by Layer (1 → 4)
4. Fix Layer 1 errors first (rare; usually type/import issues in Web/Types.hs)
5. For each failing module in Layer 2–3:
   a. Read current module state
   b. Apply targeted fix (one module at a time)
   c. Wait for ghcid "Reloading..." + result
   d. If still failing: re-read error, apply next fix
   e. If 3 attempts fail: escalate — flag_for_human with module name and error
6. After Layer 3 clean: fix Layer 4 (FrontController/Routes)
7. "All good (N modules)" in log = build clean

Layer discipline (never violate):

• Never modify Layer 1 (Web/Types.hs, build/Generated/*.hs) during error-fix loops
• Layer 1 changes invalidate ALL 59 controllers and 120 views simultaneously
• Fix within the layer where the error is reported; escalate if the fix requires Layer 1

Tasks

E1 — Start compile-check and capture initial error set

id: E1
status: done
priority: high
state_hub_task_id: "0ddc0559-55a4-405d-b568-afabcf9d2242"

Run scripts/compile-check --bg and read /tmp/ihub-compile-errors.txt. List all failing modules and their layers.

E2 — Fix Layer 2 errors (Application/Helper/*.hs)

id: E2
status: done
priority: high
state_hub_task_id: "2cd3dbb3-32d6-4348-8c04-e820feff96c0"

Fix all errors in Application/Helper/*.hs. Verify via ghcid reload. Mark done when Layer 2 shows no errors.

E3 — Fix Layer 3 errors (Web/Controller/.hs and Web/View/**/.hs)

id: E3
status: done
priority: high
state_hub_task_id: "99c4345c-57fa-4e00-afa3-3d10d948ba02"

Fix errors in controllers and views. Work module-by-module, bottom-up. Mark done when Layer 3 shows no errors.

E4 — Fix Layer 4 errors (Web/FrontController.hs, Web/Routes.hs)

id: E4
status: done
priority: medium
state_hub_task_id: "c5dda487-b091-4ce8-b7ad-782d2c462298"

Fix wiring errors last. Mark done when ghcid reports "All good, N modules loaded".

E5 — Commit clean build and close WP-0014/A1

id: E5
status: done
priority: medium
state_hub_task_id: "e20d48ea-6819-4222-a614-7dce74951e7c"

After "All good" state:

1. Commit all fixes with fix(WP-0017): reach clean build
2. Update workplans/IHUB-WP-0014-pre-flight-deployment-gaps.md A1 status to done
3. Mark this workplan done

Exit Criteria

• ghcid reports "All good, N modules loaded" with no errors
• All fixes committed
• WP-0014/A1 closed
