phase: 95_read_truncation_cap
All gates are green. Final verification is complete — no fixes were needed; the phase is fully implemented and passing.

**Phase 95 final verification report**

- Verified all 3 tasks already implemented (task files in `complete/`): read cap + notice + `ToolResultPiece` (task 01), `tool_result` SSE + live/saved/shared marker (task 02), E2E suite (task 03).
- Code checks passed: `BOR_READ_MAX_CHARS` (default 128 000, validator), pinned `READ_TRUNCATION_NOTICE` + `TRUNCATION_MARKER`, byte-identical at/under-cap read, holder `read_truncations` (no `tool_calls` impact), piece order (after `tool`, before next round), `ChatToolResultEvent`, `ToolCall` back-compat fields, `app.js` live/restore handlers, `shared.js`, `.truncated-note` CSS, `.env.example` entry, mock-LLM echo script.
- **Tests:** `uv run pytest` → 1966 passed; `uv run pytest --cov=app --cov-report=term-missing` → all green, TOTAL **99%** (>90% gate).
- **E2E:** `uv run pytest tests/e2e/test_read_truncation_cap.py -v --no-cov` → **3 passed** (frame order + live marker + LLM notice via echo; save→shared fidelity; short-read control).
- **Regression (isolated):** `test_agent_document_tools` 4 ✓, `test_chat_history` 5 ✓, `test_share_chat` 4 ✓, `test_big_read_progress` 4 ✓, `test_stop_generation` 3 ✓.
- **Lint/types:** `uv run ruff check .` → All checks passed; `uv run pyright` → 0 errors, 0 warnings.

**Completion criteria:** ① over-cap read → first-cap-chars + marker + pinned notice — ✓ (unit-pinned: at-cap/cap+1/notice tests); ② user marker live/saved/shared — ✓ (E2E + frontend tests); ③ at/under cap byte-identical, no frame — ✓ (unit + control E2E); ④ top-2 `<documents>` retrieval untouched — ✓ (`app/rag/retriever.py` unmodified vs HEAD); ⑤ suite green, >90% coverage, ruff+pyright clean — ✓; ⑥ no completed-phase behavior change — ✓ (all gates green; commit left to harness per pass rules).

- No defects found; no changes made this pass. Next pending phase: none in `todo/` (96 is the next free number).

# BOR_SUGGESTIONS=["How is my Kubernetes cluster set up?"] # JSON seed chips — shown only before any question has been saved (phase 80)
# --- Import sources (git; phase 28, admin-managed since phase 35) ---
# Comma-separated git repo URLs; import_docs clones each (first run) or
# pulls it (subsequent runs) into BOR_SOURCES_DIR/<repo-name>/ and indexes
# the result. Auth via URL (e.g. an https token) or SSH keys.
#
# Phase 35 (owner permission 2026-08-26): the PRIMARY way to manage the
# list is the admin Git sources page (http://localhost:8000/git-sources.html)
# — rows stored in Postgres (git_sources table, migration 0006). This
# variable is the EMPTY-TABLE FALLBACK: it only applies while the admin
# list is empty; once the page has stored any source, this variable is
# ignored (the page is the source of truth). Empty table + empty variable
# + no local rows = no sources (import_docs falls back to --source / the
# old ~/Homelab + ~/Deployments defaults; the UI Sync button fails loudly
# with "no sources configured (git or local)").
#
# Phase 38: this env fallback is GIT-ONLY. Local directory sources (an
# existing, non-git directory on the server) have NO env var — the DB is
# the local-source registry: add them on the same admin page (the
# "Add a local directory" form, kind 'local' + path, migration 0007).

# Phase 49: uploaded source archives (the Sources page upload form).
# An uploaded .tar / .tar.gz / .tgz / .zip is unpacked to
# BOR_UPLOAD_DIR/<name>/ where <name> is the filename minus the archive
# suffix (homelab.tar.gz -> homelab/). Re-uploading the same name
# replaces the folder's content IN PLACE — one folder, one row, no
# missing window; a failed upload never touches the existing folder,
# row, or KB. Deliberately separate from BOR_SOURCES_DIR (git checkouts).
