+# BytePort Sladge Refresh
+
+## Goal
+
+Repair the live BytePort README Sladge gap in an isolated worktree while
+preserving unrelated canonical Go, workflow, and SPEC edits.
+
+## Outcome
+
+- Created `BytePort-wtrees/sladge-current`.
+- Added the Sladge badge to `README.md`.
+- Preserved canonical `BytePort` unrelated local changes.
+
+## Validation
+
+See `06_TESTING_STRATEGY.md`.

+
+## Current State
+
+- Canonical checkout: `BytePort`
+- Active branch: `ci/add-golangci-lint`
+- Current HEAD before work: `bacb6ac6`
+- Canonical local changes before work: workflows, `SPEC.md`, Go modules, and
+  backend source files.
+
+## Badge Applicability
+
+The README describes BytePort as a deployment and portfolio platform that uses
+an LLM to generate showcase metadata and project descriptions. Sladge
+disclosure is appropriate.
+
+## Checkout Notes
+
+The isolated worktree emitted pre-existing LFS pointer warnings for tmp build
+artifacts during checkout, but `git status` and `git lfs status` reported no
+staged or unstaged changes before the README/session-doc patch.

+## Acceptance Criteria
+
+- Add the Sladge badge to the README badge block.
+- Keep source, workflow, SPEC, and dependency files untouched.
+- Preserve canonical unrelated local changes.
+- Run focused validation and lightweight repo-native checks.
+
+## Risk Notes
+
+This repository has a large checkout and prior worktrees emitted LFS pointer

+# BytePort Sladge PEM Refresh

+## Goal
+
+Refresh BytePort Sladge evidence from the current clean

+
+## Outcome
+
+- Created isolated worktree `BytePort-wtrees/sladge-pem-current` from

+- Used `GIT_LFS_SKIP_SMUDGE=1` for the worktree after a normal checkout

+# Research
+
+## Local State
+
+- Canonical `BytePort` was clean on `fix/add-pem-gitignore` at `38d6ce90`.
+- Existing prepared branch `docs/byteport-sladge-current` was not a
+  fast-forward from current canonical head: `git rev-list --left-right --count`
+  reported `4 1`.
+- Repository instructions require feature work under
+  `repos/BytePort-wtrees/<topic>/`.
+
+## Sladge Target Rationale
+
+`CLAUDE.md` describes BytePort as an IaC deployment and portfolio UX generation
+platform with optional OpenAI or LLaMA integration for enhanced template text,
+making the README badge appropriate governance disclosure.

+## Acceptance Criteria

+- The README shows the Sladge badge near the existing status badges.

+
+## ARUs
+
+- Assumption: This is a documentation/governance disclosure only.
+- Risk: BytePort has tracked LFS-like build artifacts that can dirty worktrees

+- Uncertainty: Go validation may still be limited by local build cache or disk

+# Known Issues
+
+## Superseded Branch
+
+The older `docs/byteport-sladge-current` branch at `691049c7` diverged from
+current canonical head and should be treated as stale evidence after this
+refresh.
+
+## LFS Checkout Artifacts
+
+A normal worktree checkout produced non-pointer LFS artifacts under
+`backend/byteport/tmp/`. The refresh worktree was recreated with
+`GIT_LFS_SKIP_SMUDGE=1` to keep the intended change isolated.
+
+## Backend Go Build Blocker
+
+`GOCACHE=/tmp/byteport-go-build-cache go test -v ./...` from
+`backend/byteport` runs library tests successfully but fails the root package
+build because `main.go` has pre-existing unused imports:
+

+## Results
+
+- `git diff --check` passed.
+- README badge search with `rg` passed.
+- `git lfs status` only reports the intended README modification after the

+# Governance Worklog
+
+### 2026-04-29 | GOVERNANCE | Sladge badge rollout
+
+**Context:** The projects-landing AI slop governance WBS is rolling the sladge
+badge into repos where LLM behavior is material to the product surface.
+
+**Finding:** BytePort's README describes an IaC deployment and portfolio platform
+that uses an LLM to generate showcase metadata for developer projects.
+
+**Decision:** Add the sladge badge to the README near the project title and keep
+the rollout as documentation/governance metadata only.
+
+**Impact:** BytePort is now marked consistently with the broader LLM-heavy badge
+rollout without changing runtime code or catalog metadata.
+
+**Tags:** `[BytePort]` `[GOVERNANCE]` `[sladge]`
