Phase 75 (TODO.md L4): "Save as doc" now drafts a document from the
ENTIRE chat session — every question and answer up to the click, in
order — instead of only the clicked bubble's answer; the existing
doc-edit screen's free-form body editing is how the user edits out
anything they don't want to keep from previous replies (no new UI
surface).
Task 01 (frontend):
- app.js buildSessionTranscript(): walks the bor.chat.v1 conversation
record in order — a numbered section per user turn ("## N.
<question, raw>" + blank line + the raw answer text; more answers
join under the same heading), sections blank-line separated, all
trailing whitespace collapsed to one final newline. Only the raw
persisted text travels (m.who + m.text — no thinking blocks, no
source chips, no tune metadata); a brain record before the first
user record is skipped; a heading-only section marks a user turn
whose answer never landed (A6, owner-confirmed 2026-09-08).
- saveAsDoc(btn): the draft body is buildSessionTranscript(); the
dead single-bubble markdown parameter is dropped (the button's
appendSaveAsDocButton signature is unchanged — one button per
bubble). Title/path/double-click guard/hand-off are unchanged
(defaultDocTitle: the last question, whitespace-collapsed,
<=120 chars; docs/<slug>.md).
- Unit: the app.js source pins move to the transcript shape (whole
session, no thinking, no dead parameter).
Task 02 (E2E):
- tests/e2e/test_save_doc_session.py (bare-repo fixture, the
phase-59 convention — git as source of truth): three DISTINCT
on-topic turns in one session (turn 1 carries the phase-17
"think out loud" trigger so its record has a thinking block the
transcript must exclude) -> save on the LAST bubble -> the
prefilled body is ## 1./## 2./## 3. in order, byte-exact against
the deterministic mock, thinking-free -> edit the whole
section-2 block out of the body -> push -> git show
bor-docs:<path> equals the EDITED body byte-for-byte (section 2's
question and answer provably absent; sections 1 and 3 byte-exact;
the UI's sha prefix is git rev-parse bor-docs). Second test:
the button on the FIRST bubble still drafts the whole session
(A6 — the transcript is the session at click time, title stays
the last question); canceling leaves the branch tip untouched.
- tests/e2e/test_response_to_docs.py: the phase-59 single-turn body
expectation moves to the transcript shape ("## 1. <question>" +
the answer's markdown) — the rest of the suite unchanged.
Also lands the phase-74 file moves (00_phase.md /
03_mock_marker_e2e.md -> complete/) and the phase reports — the
house convention of committing .agents/ with the phase.
Phase 74 (TODO.md L4): a follow-up question now reaches the model WITH
the conversation so far — every prior user/brain turn and the prior
thinking blocks on brain turns (preserve-thinking) — while
POST /api/chat stays stateless (A10): the client provides the history
in the request body and the server stores nothing new.
Server (task 01):
- ChatRequest.history: optional list[HistoryTurn] (who: user|brain,
text, optional thinking) — absent/empty keeps the request
byte-identical to pre-phase-74 (the two-message [system, user]
request; the kill-switch semantics are pinned in the integration
suite).
- app.rag.prompts.history_to_messages: pure mapper — walks the turns
newest-first against the settings budgets (history_max_turns=40 /
history_max_chars=24000, BOR_HISTORY_MAX_TURNS /
BOR_HISTORY_MAX_CHARS); a capped turn is dropped WHOLE (never cut
mid-answer); the kept window is returned oldest-first; brain turns
carry their thinking as reasoning_content (A4) only when
non-empty.
- Both branches feed it: the deflected path splices it between the
system prompt and the current user message (the phase-71 recovery
still rebuilds from messages[1:]), the grounded agent receives
run_agent(..., history=hist); llm.py's message params widen to
list[dict[str, Any]] (string-only messages stay byte-identical on
the wire — the SDK passes message dicts through verbatim).
- The per-turn log line (PLAN §9) gains history_msgs=N after
kb_chars=N.
- Pins: tests/unit/test_history.py (mapper: mapping, reasoning
gating, both budgets, drop-whole, ordering, empty default),
tests/unit/test_config.py (the two settings + env overrides),
tests/unit/test_agent.py (the history splice + the default),
tests/integration/test_chat_api.py (deflected AND grounded forward
the history incl. reasoning_content, no-history byte-identity, 422
pins, the log field).
Client (task 02):
- runTurn — the single funnel for fresh send / phase-49 retry /
phase-53 stale-regen — sends history = the conversation record
minus the current question, with thinking only on brain records
that streamed one (undefined drops the key from the JSON, the
record's convention); the question is never duplicated into the
history.
Wire proof (task 03):
- The mock's echo my history marker (HISTORY_TRIGGER) answers with
the deterministic history echo — history: N prior messages; last
answer tail: <last 24 chars>; thinking: yes|no — checked BEFORE
the DEFLECT_MODE branch (like TABLE_TRIGGER), so it fires on both
turn branches whatever the gate says; the module docstring records
the user/assistant-only history invariant that keeps every
existing (tool-result-classified) marker flow unaffected.
- tests/e2e/test_llm_history.py (isolated): a grounded follow-up and
a deflected follow-up both receive history: 2 prior messages +
thinking: yes + the byte-exact tail of turn 1's answer (derived
from the persisted bor.chat.v1 record — the same array the client
maps into the body); a cold start receives history: 0 prior
messages / last answer tail: none / thinking: no.
- Regressions green in isolation: chat_rag, chat_history (phase 50),
agent_document_tools, harness_aligned_tools, stop_generation,
retry_answer, response_to_docs.
Root cause (task 01): none of C1-C3 - in Chromium 151 (real mode) a
merely-hidden tab neither stops the stream (frames arrive at full rate;
turn completes) nor fires pagehide on tab switch; C1's double-record
path was proven latent via a synthetic pagehide (trigger is
browser-dependent, e.g. Safari) and C2 (the 120s pre-token guard) was
confirmed to fire while hidden.
- C1: the pagehide partial-persist is correlated with the turn's settle
(leavePartialIndex) - the done/stop settle REPLACES it in place
(identity-guarded rememberBrainTurn in-place mode), so bor.chat.v1
and the auto-saved saved_chats row keep exactly ONE brain turn per
question; a real navigation never runs a settle, so the leave-save
is unchanged.
- C2: the visibility re-arm gives the still-armed pre-token guard a
fresh TURN_TIMEOUT_MS when the tab returns to visible - hidden time
no longer counts toward the 120s guard.
- Phase-48 teardown contract untouched: Stop / tab close / real
navigation still cancel the fetch and stop the model.
- Unit pins: tests/unit/test_frontend_hidden_tab.py (the app.js
mechanisms without a browser).
- E2E pins: tests/e2e/test_hidden_tab_stream.py - synthetic pagehide
mid-stream completes exactly once with one brain turn (localStorage
+ auto-saved row), reload restores one bubble, no-event baseline,
and the fake-clock pre-token guard re-arm (discriminating: fails
with the re-arm disabled).
Convert the two unchecked TODO items into executable phases (Protocol B,
appended after the 72 completed phases):
- 73_hidden_tab_stream (TODO L3): a merely-hidden browser tab must never
stop a generating answer; repro/root-cause decision tree + the pagehide
partial-correlation fix + the hidden-tab E2E pin.
- 74_llm_chat_history (TODO L4, history): client-provided history in
POST /api/chat (stateless, A10) mapped through both the deflected and
grounded agent paths, prior thinking blocks preserved via
reasoning_content, capped oldest-first; mock echo marker + E2E.
- 75_save_doc_full_session (TODO L4, save-as-doc): the Save-as-doc draft
body becomes the full session transcript; edit-out happens in the
existing doc-edit body; multi-turn git-verified E2E.
Owner-confirmed assumptions A1-A7 are recorded as ASSUMPTION lines in the
task files. TODO.md is cleared (items now live in .agents/phases/todo/).
Standardize on the .agents/ directory (shared with project skills):
phases/, user_stories/, reports/, screenshots/, validate.sh, and
phase-sessions/ + pipeline.log all move to .agents/ (git mv preserves
history; runtime artifacts move alongside).
Updates every reference in AGENTS.md, README.md, .gitignore, app
docstrings, and test story headers. Historical KB content in data/
and the runtime pipeline.log transcript are left untouched.
Codifies the 2026-09-05 turbo comparison workflow as a project skill under
.agents/skills/: switch BOR_LLM_CHAT_MODEL in .env, run the fixture gate
(twice, for variance) + the locked derived gate with per-turn wall timing,
interpret the two metrics against the reference model rates (re-read habit:
lite ~100%, turbo ~12%; usage-floor MISS as test artifact; caps as real
regression), record the verdicts byte-exact in TOOL_CALLING_TESTING.md, and
commit the doc. Rules baked in: never touch the battery/thresholds/fixtures,
never edit app code, never commit .env.
