feat(cli,tui): issue #12 — presenter contract semantics amendment (v0.2.0)

Replaces the stateless _render_event / _render_event_to_log helpers with
stateful per-turn presenters (CliPresenterState / TuiPresenterState).
Coalesces thinking-event deltas into a single growing display per run;
demotes telemetry events with editorial hierarchy; formats duration +
usage for human reading. Headline behavior change: a 50-token thinking
phase now renders as ONE coalesced growing line in CLI (or one closed
RichLog entry + per-delta live Static widget in TUI), not 50 lines of
[thinking] spam.

Editorial promotion line (issue #12 INV-002):
- Load-bearing (no demotion prefix): Text, Done, Error, Cancelled
- Demoted telemetry (`. ` ASCII prefix in CLI; dim `· ` in TUI):
  WorkerPhase, Thinking, TextBoundary, ToolStart, ToolResult

Stateful coalescing:
- Thinking deltas accumulate into thinking_buffer; first non-thinking
  event closes the run with a single \n boundary in CLI / one closed
  dim RichLog entry in TUI.
- TUI adds a dedicated Static(id="thinking-current") widget that shows
  the last ~200 chars of the active run, mirroring per-delta updates.
  Two-views-of-thinking decoupling per INV-004: chronological RichLog +
  always-visible widget.
- CLI INV-005: when stdout text was streamed mid-line,
  text_written_since_newline triggers a stdout flush + \n before the
  next stderr terminal label — guarantees [done] / [error] / [cancelled]
  land on their own line in a TTY without breaking pipe-to-file
  scripted consumers.

Formatting helpers (issue #12 INV-006 / INV-007):
- _format_duration_ms — autoscale `347ms` / `5.5s` / `1.2m`
- _format_usage — natural-language `6756 in -> 126 out (6882 total, 0
  cached)` with arrow="->" CLI / "→" TUI

Cross-frontier design pass (eitri-smithy-dev, althing
01KSBE52YZR5E3SPTKA672JE43) returned 16-of-16 confirmed decisions + 4
material divergences applied:
- ASCII `. ` prefix in CLI (`·` is U+00B7, not ASCII)
- RichLog one-closed-entry-per-run + Static per-delta updates (not
  inline-mirror as initially proposed)
- presenter-state object instead of pure-function rendering
- Framed as "contract semantics amendment", not "polish"

Volva paraphrase round (5 prose-precision fixes applied to
12.contract.md): INV-001 "growing display" semantics; single hide
mechanism for the Static widget (Textual reactive `display: bool`);
[render_error] security clause (type-only, no exception message);
text_written_since_newline `\n`-terminated text corner case;
[create_session] integration path (bypasses state.render — not an SSE
Event variant).

Volva code-review round (5 findings applied):
- F1 drift: render-exception fallback now writes BOTH a plain-label
  fallback line for the original event AND the `[render_error] <type>`
  line (was missing the fallback half).
- F2 drift: dim Rich style applied to all demoted-telemetry RichLog
  writes via `rich.text.Text(..., style="dim")` (was plain str).
- F3 drift: belt-and-braces widget clear+hide on EVERY terminal event
  (Done/Error/Cancelled), even when thinking_open was False.
- F4 precision: _format_usage gains PRE-001 assertion on the four
  expected usage keys.
- F5 precision: _run_turn signature amended in issue #3 contract to
  document the new `state: CliPresenterState | None = None` test-
  injection kwarg.

[create_session] lifecycle line demoted to `. create_session:` (written
directly by _amain; bypasses state.render since it's not a wire-level
SSE Event variant). Pre-amendment _render_event / _render_event_to_log
and their test classes removed under the no-backwards-compat rule.

Issues #3 and #4 contracts amended in-place: #3 (CliPresenterState
CLASS + FN block + helper FN blocks + _run_turn signature + _amain
create_session demotion); #4 (TuiPresenterState CLASS + FN block +
compose Static widget + _stream_turn_worker state construction).

209 tests GREEN; ruff clean. Bumps v0.1.0 → v0.2.0 (minor — output
shape change breaks pre-amendment grep patterns like `[thinking] '`;
no public API surface change beyond the rendering contract).

Persistent-memory commit-along: captures the issue #12 decision,
forward direction (require end_user_id for every access — declined
worldtree-dev's requires_end_user_id offer because we'll send it
universally), and the Heimdall scope-model foot-gun note (the
"per-Tier-1-agent scope add" diagnosis was a phantom ask resolved by
worldtree-dev's correction; agent.call:* baseline covers all Tier 1).

scope: "Presenter contract semantics amendment — replace stateless 'one labeled line per non-Text event' rendering with stateful event coalescing + visual hierarchy.

Thinking deltas coalesce into a single growing run, closed on the first non-thinking event.

Two parallel in-place amendments to issues #3 (cli) and #4 (tui), landing in one commit at v0.2.0. Mission refinement (per persistent-memory amendment): 'the observability surface presented at the right zoom level for the operator's task' — raw per-event streaming is the wrong zoom for debugging; coalesced thinking + demoted telemetry is the right zoom."
depends_on:
- "ratatoskr.sse_client"
used_by: []
language: "python"
complexity: "medium"
estimated_loc: 220
confidence: 0.85
assumptions:
- "Worldtree event sequencing per the v0.19.0 spec pin is `Thinking* WorkerPhase Text* (ToolStart ToolResult)* Done`, with WorkerPhase and Text optionally interleaved across thinking runs (e.g., `Thinking* WorkerPhase Text* Thinking* Text* Done`). The closure trigger 'first non-thinking event' is correct for every interleaving pattern in the spec; multiple thinking runs each get their own coalesced display."
- "The presenter-state object is a small per-turn-spawned dataclass-style structure, not a long-lived singleton. CLI: new state per `_amain` call. TUI: new state per `_stream_turn_worker` invocation (one per turn). Reset semantics fall out of construction — no explicit reset method needed."
- "TUI's `Static(id='thinking-current')` widget is composed once at app startup (during `compose()`); the widget is hidden by setting `widget.display = False` AFTER the compose pass (in `on_mount`, or constructed with `display=False` if the Static constructor supports it — implementer's mechanical call). Visibility toggle uses Textual's reactive `Widget.display: bool` attribute throughout (`widget.display = True` to show, `widget.display = False` to hide). The contract does NOT use CSS `classes='hidden'` or direct `widget.styles.display` mutation — those are equivalent in effect but mixing them in one contract creates implementation-spec churn. Clear + hide happens on the turn-terminal event (`Done` / `Error` / `Cancelled`)."
- "CLI stdout/stderr split stays intact: stdout = LLM text content; stderr = everything else. The TTY-interleave problem is solved by `text_written_since_newline` state — when about to render a terminal label, if text has been written, flush a `\\n` to stdout first. Scripted consumers piping `--send '...' > out.txt` are not affected."
- "Per-delta flush in CLI (~50× per turn for a long thinking phase) is acceptable. Real-time observability requires per-delta visibility; batch-buffering adds latency without meaningful CPU savings."
- "ASCII-only prefixes in CLI output (`. `, `->`) for scriptability across non-UTF8 terminals + log redirects. TUI may use Unicode (`· `, `→`) since it already commits to UTF-8 terminal assumptions via Textual."
- "No new CLI flags. The renderer's choices ARE the product. `--quiet` / `--debug` / `--verbose-events` toggle complexity is rejected until a concrete scripted-caller use case demonstrates real demand."
- "Editorial promotion line is stable: load-bearing = `Text`, `Done`, `Error`, `Cancelled` (the model's voice + terminal outcomes); demoted = `WorkerPhase`, `Thinking`, `TextBoundary`, `ToolStart`, `ToolResult` (streaming telemetry + tool activity). Tool events are debug-important but visually compete with assistant text; a future Tools pane (design-brief §5) may promote tool details there without changing this transcript contract."
- "Cross-frontier design pass with eitri-smithy-dev (althing thread 01KSBE52YZR5E3SPTKA672JE43, 2026-05-23) confirmed 16 of 16 originally proposed decisions. 4 material divergences applied: (a) `·` is U+00B7 not ASCII, use `. ` in CLI; (b) RichLog gets one closed-entry-per-run + Static gets live per-delta updates (not inline-mirror); (c) presenter-state object instead of stateless functions; (d) frame as 'contract semantics amendment' not 'polish'."
open_questions:
- "Should we eventually expose a `--debug` flag that renders the pre-v0.2.0 raw-event-per-line shape for the case where coalescing hides something? Draft: no — `git checkout v0.1.0` is the escape hatch until a concrete use case demands the flag. Defer to follow-up issue if it surfaces."
- "Should the TUI `Static(id='thinking-current')` widget use Rich markup for emphasis (italic-dim) or stay plain text? Draft: plain text for v0.2.0; revisit if visual hierarchy proves insufficient. Rich markup inside Static requires `markup=True` which then needs careful escape handling for user-supplied content."
- "Should `ToolResult.result` get smarter truncation (parse-aware for known shapes vs the current `{!r:.200}` repr-truncate)? Draft: no for this pass — same truncation behavior as today; the demotion + prefix change is the visual fix. Smart truncation is a separate Tools-pane-shaped concern."

# Presenter contract semantics amendment — stateful event coalescing + visual hierarchy
## Context
A 2026-05-23 mimir smoke against personal Worldtree (post-v0.1.0 commit
`804c2df`) exposed that the current presenters
(`cli._render_event` and `tui._render_event_to_log`) render every Worldtree
SSE event as a labeled line, with no visual hierarchy and no coalescing.
Concrete problems observed:
1. **Thinking deltas spam.** Worldtree streams thinking as token-deltas
(just like text). The current renderer writes one `[thinking] '<token>'`
line per delta. A 50-token thinking phase = 50 lines.
2. **text_boundary fires inline** mid-text, visually breaking sentences.
3. **worker_phase renders** with the same visual weight as actual model
output, drowning load-bearing signal.
4. **ToolStart / ToolResult** share the telemetry-vs-transcript tension.
5. **duration_ms / usage** are unformatted (`duration_ms=5467`,
`usage={'prompt_tokens': 6756, ...}`).
6. **`[done]` on stderr interleaves** with stdout text in a TTY because
there's no newline-boundary guarantee between the two streams.
Per persistent-memory: "the product IS the observability surface; chat is
the input mechanism." Suppressing events is the wrong direction. The right
direction is rendering them cleanly, with editorial judgment about what's
load-bearing transcript vs demoted telemetry.
This amendment refines the mission slightly: **"the observability surface
presented at the right zoom level for the operator's task."** Per-event
raw streaming is the wrong zoom for normal debugging; coalesced thinking
+ demoted telemetry is the right zoom. Design pass was cross-frontier
consulted with `eitri-smithy-dev` (althing thread
`01KSBE52YZR5E3SPTKA672JE43`); 16 of 16 original decisions confirmed
with 4 material divergences applied (see assumptions).
## Data flow
**Input:** unchanged. Same `Event` discriminated union from
`ratatoskr.sse_client` (`WorkerPhase | Thinking | Text | TextBoundary |
ToolStart | ToolResult | Done | Error | Cancelled`).
**Output change (both presenters):**
- Thinking deltas: instead of one line per delta, single growing
run closed on the first non-thinking event.
- Demoted telemetry (WorkerPhase, Thinking, TextBoundary, ToolStart,
ToolResult): visual demotion — `. ` prefix in CLI stderr, dim style
+ `· ` prefix in TUI RichLog.
- Load-bearing terminal events (Done, Error, Cancelled): no demotion
prefix; CLI guarantees a `\n` to stdout BEFORE the label is written
to stderr when text has been written this turn.
- `duration_ms` formats: `347ms` / `5.5s` / `1.2m` autoscale.
- `usage` formats: `6756 in -> 126 out (6882 total, 0 cached)` ASCII
arrow in CLI; `→` Unicode arrow in TUI.
**Output change (TUI-only):**
- New `Static(id="thinking-current")` widget composed in
`RatatoskrApp.compose()`. Hidden by default. Updated per Thinking delta
with the last ~200 chars of accumulated thinking. Hidden + cleared on
turn-terminal event.
- RichLog receives ONE closed thinking entry per thinking-run (not
per-delta). Static widget gets per-delta updates.
**Side effects:** none new. Same outbound HTTP, same SSE consumption.
No persistence.
## Invariants
- **INV-001 [hard]**: Thinking coalescing — every consecutive run of
`Thinking` events MUST render as a single growing display. The CLI
emits MULTIPLE writes to stderr (one `. thinking: ` prefix on the
first delta of the run, then one write per subsequent delta with no
intervening `\n`), composing ONE logical stderr line that is
terminated by a single `\n` written at closure. The TUI emits
per-delta updates to the `thinking-current` Static widget AND, at
closure, ONE RichLog entry containing the full accumulated run
content. The closure trigger is the first non-thinking event arrival,
including terminal events (`Done` / `Error` / `Cancelled`).
Multiple thinking runs in one turn each get their own coalesced
display; the state machine resets on closure and re-opens on the
next `Thinking` event.
- **INV-002 [hard]**: Editorial promotion is fixed:
**Load-bearing:** `Text`, `Done`, `Error`, `Cancelled` (the model's
voice + terminal outcomes — no demotion prefix).
**Demoted telemetry:** `WorkerPhase`, `Thinking`, `TextBoundary`,
`ToolStart`, `ToolResult` (streaming telemetry + tool activity —
demotion prefix in CLI and TUI).
Adding or moving an event variant between the two groups is a
contract change.
- **INV-003 [hard]**: Demotion visual treatment:
- **CLI**: `. ` prefix on every demoted-event stderr line. ASCII-only
(no `·` Unicode, no ANSI dim). Load-bearing events get no prefix.
- **TUI**: dim Rich style + `· ` prefix on demoted-event RichLog
entries. Load-bearing events get no demotion.
- **INV-004 [hard]**: TUI two-views-of-thinking:
- The dedicated `Static(id="thinking-current")` widget receives
per-delta updates showing the last ~200 chars of the current
accumulated thinking-run content (`…` prefix when truncated).
- The RichLog transcript receives ONE closed entry per thinking-run
written at closure time, content = the full accumulated thinking
text (dim, `· ` prefix).
- The two views are decoupled: per-delta widget update fires for
every `Thinking` event; per-run RichLog write fires once on
closure. No per-delta RichLog writes for Thinking events.
- **INV-005 [hard]**: CLI stdout/stderr newline boundary — before
writing any load-bearing terminal label (`[done]`, `[error]`,
`[cancelled]`) to stderr, the renderer state MUST check
`text_written_since_newline`; if true, write `\n` to stdout and
flush, then reset the flag, then write the terminal label to stderr.
This guarantees the terminal label lands on its own line below the
assistant text in a TTY. (Scripted consumers piping stdout to a file
see the same `\n` cleanly terminating the text.)
- **INV-006 [hard]**: Duration formatting via shared helper
`_format_duration_ms(ms: int) -> str`:
- `ms < 1000``"347ms"`
- `1000 ≤ ms < 60_000``"5.5s"` (one decimal)
- `ms ≥ 60_000``"1.2m"` (one decimal)
- **INV-007 [hard]**: Usage formatting via shared helper
`_format_usage(usage: dict, *, arrow: str) -> str`:
Input: `{"prompt_tokens": int, "completion_tokens": int,
"total_tokens": int, "cached_input_tokens": int}`.
Output: `f"{p} in {arrow} {c} out ({t} total, {ci} cached)"`.
`arrow="->"` in CLI (ASCII), `arrow="→"` in TUI (Unicode).
- **INV-008 [hard]**: Presenter-state lifecycle:
- One `CliPresenterState` instance constructed per `_amain` call;
discarded on return.
- One `TuiPresenterState` instance constructed per
`_stream_turn_worker` invocation (one per turn); discarded when
the worker exits (success, error, or cancellation).
- No long-lived singleton; no cross-turn state in either presenter.
- **INV-009 [hard]**: TUI render-exception fallback — if any exception
fires inside `TuiPresenterState.render()` (e.g., the
`thinking-current` widget reference goes stale during teardown), the
exception MUST be caught at the presenter boundary; the original
event MUST still be rendered as a plain labeled RichLog line (the
pre-amendment behavior); a visible `[render_error] <type>` line MUST
be written to the RichLog so the operator sees the degradation.
Format is the exception class name ONLY — NOT the exception message
/ args — because exception payloads can contain wire data from the
original event (e.g., `AttributeError`'s repr of the event object).
The `[security]` constraint trumps the readability win of including
`<msg>`; the operator can attach a debugger or read logs if the
bare `<type>` doesn't pinpoint the cause. Silent-swallow remains
forbidden.
- **INV-010 [hard]**: No new public CLI flags. `--quiet`,
`--verbose-events`, `--debug`, `--no-thinking` are out of scope. The
renderer choices ARE the product. Adding a flag is a separate
contract amendment with its own demand-evidence.
- **INV-011 [hard]**: No `core.*` / `worldtree.*` imports (existing
boundary; unchanged). No new third-party deps. Existing dependencies
on `httpx`, `httpx-sse`, `textual`, `rich` cover the surface.
## Out of scope
- **`--quiet` / `--debug` / `--verbose` flags.** Per INV-010.
- **Side-pane work** (AdminEvents, Persona, Tools, BifrostState,
ServerLog per design-brief §5). The dedicated TUI thinking widget
added here is the foundation but is NOT a "Persona pane" or any
other named §5 pane. Future side-panes may relocate thinking
rendering; this amendment fixes the current chat-pane shell.
- **i18n / locale-aware formatting.** English-only Vuong-only.
`5.5s` is locale-blind by design.
- **Cross-process resume / transcript persistence.** Per design-brief
§8d, deferred to v2.
- **Smart truncation of `ToolResult.result`** beyond the existing
`{!r:.200}` repr-truncate. Same shape as today; the demotion +
prefix change is the visual fix. Smart per-tool-result-shape
truncation is a Tools-pane-shaped concern.
- **Replay of pre-amendment behavior** via a `--legacy-render` flag.
`git checkout v0.1.0` is the escape hatch.
## Constraints
- **[compatibility]** Spec pin unchanged. The wire surface
(`Event` union from `ratatoskr.sse_client`) is unchanged; only the
rendering of those events changes.
- **[performance]** Per-delta flush in CLI is acceptable (real-time
observability requires it). The state object is a small dataclass;
per-render overhead is negligible relative to the SSE stream
cost.
- **[security]** Same as today — no logged credentials. The
`[render_error]` fallback (INV-009) MUST NOT include
exception-payload content that could leak request data.
- **[style]** Ruff line-length=100. ASCII-only in CLI presenter
output; Unicode allowed in TUI. Type-hinted `PresenterState` classes
with `dataclass(slots=True)` for memory efficiency.

## In-place amendments to issue #3 (`ratatoskr.cli`)
### `CLASS CliPresenterState` (NEW)
```contract
CLASS CliPresenterState
BRIEF: Stateful presenter for the cli `--send` mode. Owns per-turn rendering state: in-flight thinking buffer + whether a thinking run is currently open + whether stdout text has been written since the last newline. One instance per `_amain` call; discarded on return.
PROPERTIES:
thinking_buffer: list[str] # accumulated thinking content for the active run
thinking_open: bool # whether a thinking run is currently open
text_written_since_newline: bool # whether stdout has received text without a closing \n
METHODS:
render(event, *, stdout: TextIO, stderr: TextIO) -> None
INV-WIRE-001: One instance per `_amain` call (INV-008).
INV-WIRE-002: state.render(...) is called for every event in stream order; events MUST NOT be skipped.
```
### `FN CliPresenterState.render` (NEW)
```contract
FN CliPresenterState.render(self, event: Event, *, stdout: TextIO, stderr: TextIO) -> None
BRIEF: Render one event with the editorial hierarchy per INV-002. Coalesces thinking runs per INV-001; guarantees stdout newline boundary before load-bearing terminal labels per INV-005. ASCII-only output.
PRE: [PRE-001 hard] event is an instance of one of the Event union variants -- assert isinstance(event, (WorkerPhase, Thinking, Text, TextBoundary, ToolStart, ToolResult, Done, Error, Cancelled))
PRE: [PRE-002 hard] stdout and stderr are writeable text IO objects
POST: [POST-001 side_effect] for Thinking events: open thinking run if not open, append delta to thinking_buffer, write delta to stderr without trailing newline
POST: [POST-002 side_effect] for non-Thinking events when thinking_open: close the thinking run by writing "\n" to stderr; set thinking_open=False; clear thinking_buffer; THEN render the new event
POST: [POST-003 side_effect] for Text events: write event.content to stdout without forcing a trailing newline; set text_written_since_newline = NOT event.content.endswith("\n") so already-terminated content does NOT trigger an extra newline before subsequent terminal labels (INV-005 boundary fires only when text lacks a trailing newline)
POST: [POST-004 side_effect] for Done/Error/Cancelled: if text_written_since_newline, write "\n" to stdout + flush, reset flag; then write the terminal label to stderr per INV-005
POST: [POST-005 side_effect] for demoted-telemetry events (WorkerPhase, TextBoundary, ToolStart, ToolResult): write ". <label> <fields>\n" to stderr (no prefix on load-bearing)
STEPS:
1. [setup, flexibility=prescriptive] Validate PRE-001..PRE-002
2. [branch, flexibility=prescriptive] IF isinstance(event, Thinking):
IF NOT self.thinking_open:
stderr.write(". thinking: ")
self.thinking_open = True
stderr.write(event.content)
stderr.flush()
self.thinking_buffer.append(event.content)
RETURN
3. [branch, flexibility=prescriptive] IF self.thinking_open:
# Close the open thinking run before rendering the new event
stderr.write("\n")
stderr.flush()
self.thinking_open = False
self.thinking_buffer.clear()
4. [branch, flexibility=prescriptive] IF isinstance(event, Text):
stdout.write(event.content)
stdout.flush()
# Track whether the cursor is mid-line — if content ends with \n,
# stdout is already at column 0 and INV-005 should NOT inject another \n.
self.text_written_since_newline = not event.content.endswith("\n")
RETURN
5. [branch, flexibility=prescriptive] IF isinstance(event, (Done, Error, Cancelled)):
IF self.text_written_since_newline:
stdout.write("\n")
stdout.flush()
self.text_written_since_newline = False
# Then write the load-bearing terminal label (NO demotion prefix)
label = _format_terminal_label(event) # see helpers below
stderr.write(label + "\n")
RETURN
6. [branch, flexibility=prescriptive] # Demoted telemetry: WorkerPhase, TextBoundary, ToolStart, ToolResult
label = _format_demoted_label(event)
stderr.write(". " + label + "\n")
TESTS:
thinking_coalesce_single_run [happy,tracer]: render Thinking("hello"), Thinking(" world") in sequence; stderr captures ". thinking: hello world" (no \n yet); then render Done → stderr gets a final \n + the [done] line
thinking_closes_on_first_non_thinking_event [happy]: Thinking → WorkerPhase → stderr has ". thinking: ...\n" (closed) then ". worker_phase: ..."
thinking_closes_on_error [error]: Thinking → Error → thinking line closes with \n, then [error] line rendered (no discard of partial thinking)
multiple_thinking_runs [scenario]: Thinking → Text → Thinking → Done → two separate ". thinking: ..." runs in stderr, with stdout receiving the text + \n boundary before [done]
text_then_done_newline_boundary [trace]: Text("answer") → Done; stdout receives "answer\n" (the \n is from INV-005), stderr receives "[done] ..."
no_text_then_done_no_extra_newline [trace]: Done with no preceding Text → stdout untouched; stderr receives only "[done] ..."

### `FN _format_duration_ms` (NEW helper)
```contract
FN _format_duration_ms(ms: int) -> str
BRIEF: Auto-scale duration formatting per INV-006. Locale-blind; English-only.
PRE: [PRE-001 hard] ms is a non-negative int -- assert isinstance(ms, int) and ms >= 0
POST: [POST-001 return_value] returns a short string: "<ms>ms" / "<s.s>s" / "<m.m>m"
STEPS:
1. IF ms < 1000: RETURN f"{ms}ms"
2. ELIF ms < 60_000: RETURN f"{ms/1000:.1f}s"
3. ELSE: RETURN f"{ms/60_000:.1f}m"

fractional_seconds: 5467 → "5.5s"
exact_one_minute: 60000 → "1.0m"
fractional_minutes: 72000 → "1.2m"
zero: 0 → "0ms"
```
### `FN _format_usage` (NEW helper)
```contract
FN _format_usage(usage: dict, *, arrow: str) -> str
BRIEF: Natural-language usage formatting per INV-007. `arrow="->"` in CLI, `arrow="→"` in TUI.
PRE: [PRE-001 hard] usage has the four expected keys
POST: [POST-001 return_value] returns f"{prompt} in {arrow} {completion} out ({total} total, {cached} cached)"
STEPS:
1. p = usage["prompt_tokens"]; c = usage["completion_tokens"]; t = usage["total_tokens"]; ci = usage["cached_input_tokens"]

unicode_arrow: arrow="→" → "6756 in → 126 out (6882 total, 0 cached)"
zero_cached: cached=0 → "..., 0 cached)" (literal)
```
### `_amain` STEPS amended
`_amain` now constructs a `CliPresenterState` and threads it through `_run_turn`. The old stateless `_render_event(event, stdout, stderr)` call inside `_run_turn` becomes `state.render(event, stdout=stdout, stderr=stderr)`.
The `[create_session] session_id=... agent_id=...` lifecycle line is NOT routed through `state.render()` — it is not an SSE `Event` variant (CliPresenterState.render's PRE-001 only accepts `Event` union members), and the lifecycle line fires before any stream event has arrived. It remains a direct `sys.stderr.write(...)` call inside `_amain`, with the `. ` demotion prefix applied at the call site for consistency with the rest of the demoted-telemetry hierarchy:
```python
sys.stderr.write(f". create_session: session_id={info.session_id} agent_id={info.agent_id}\n")
```
Decision (was an open question): `[create_session]` is demoted, NOT load-bearing. It's a lifecycle observability marker, not the model's voice; demoting it preserves visual hierarchy with `[done]`/`[error]`/`[cancelled]` as the only no-prefix terminal events.
### TESTS amendments (issue #3 in-place)
Existing per-event TESTS in `_render_event` block become tests on `CliPresenterState.render` with single-event sequences. New tests added for state transitions (above). The `_run_turn` tests stay; their assertions on stderr labels update for the new `. ` prefix on demoted events and the autoscale formatting.

## In-place amendments to issue #4 (`ratatoskr.tui`)
### `CLASS TuiPresenterState` (NEW)
```contract
CLASS TuiPresenterState
BRIEF: Stateful presenter for the TUI mode. Owns per-turn rendering state: in-flight thinking buffer + whether a thinking run is currently open. One instance per `_stream_turn_worker` invocation; discarded when the worker exits.
PROPERTIES:
thinking_buffer: list[str]
thinking_open: bool
METHODS:
render(event, *, log: RichLog, thinking_widget: Static, raw: bool) -> None
INV-WIRE-001: One instance per `_stream_turn_worker` invocation (INV-008).
INV-WIRE-002: Two-views-of-thinking decoupling (INV-004): thinking_widget updates per-delta; log receives one closed entry per run.
INV-WIRE-003: Render-exception fallback (INV-009): any exception in render() is caught at the boundary; original event renders as plain labeled log line + `[render_error]` log entry.
```
### `FN TuiPresenterState.render` (NEW)
```contract
FN TuiPresenterState.render(self, event: Event, *, log: RichLog, thinking_widget: Static, raw: bool) -> None

PRE: [PRE-001 hard] event is an instance of one of the Event union variants
PRE: [PRE-002 hard] log and thinking_widget are valid Textual widget references
POST: [POST-001 side_effect] for Thinking events: open thinking run if not open; append delta to thinking_buffer; update thinking_widget with last ~200 chars of buffer (… prefix when truncated); make widget visible if hidden
POST: [POST-002 side_effect] for non-Thinking events when thinking_open: close the thinking run by writing ONE dim+`· ` RichLog entry with the full accumulated thinking content; clear buffer; set thinking_open=False; clear + hide thinking_widget; THEN render the new event
POST: [POST-003 side_effect] for Text events: stream content into RichLog as raw text delta (no prefix, no demotion)

POST: [POST-005 side_effect] for demoted-telemetry events except Thinking (WorkerPhase, TextBoundary, ToolStart, ToolResult): write a dim+`· ` RichLog entry
POST: [POST-006 side_effect] on Done events with NOT raw: after the [done] line, write a Rule + Markdown render of event.response per existing issue #4 INV-005
POST: [POST-007 exception] never propagates; on any internal exception, write a plain labeled RichLog line for the original event + a `[render_error] <type>` line (class name ONLY, no exception message — INV-009 security clause); degrade gracefully

render_exception_fallback [adversarial]: monkeypatch thinking_widget.update to raise → RichLog gets a plain labeled fallback line + a `[render_error] <ExceptionClassName>` line (no message content per INV-009 security); worker does not crash

usage_format_unicode_arrow [trace]: Done → label contains "usage 6756 in → 126 out (6882 total, 0 cached)"
```
### `RatatoskrApp.compose` STEPS amended
`compose()` now yields one additional widget: `Static("", id="thinking-current")`. The widget is hidden by default — implementer either constructs with `display=False` (if Static's constructor supports it directly) OR sets `widget.display = False` in `on_mount` after compose. Visibility is toggled via Textual's reactive `Widget.display: bool` attribute (`widget.display = True/False`) per INV-004 lifecycle. The contract does NOT prescribe `classes="hidden"` + CSS or `widget.styles.display` mutation — both are equivalent in effect, but the reactive-attribute path is the chosen mechanism for this amendment to avoid implementation churn.
### `_stream_turn_worker` STEPS amended
`_stream_turn_worker` now constructs a `TuiPresenterState` at the top and threads it through the per-event loop. Replaces the existing `_render_event_to_log(event, log=log, raw=self.args.raw)` call with `state.render(event, log=log, thinking_widget=self.query_one("#thinking-current", Static), raw=self.args.raw)`.
### TESTS amendments (issue #4 in-place)
Existing per-event TESTS in `_render_event_to_log` block become tests on `TuiPresenterState.render`. New tests added for state transitions (above) and the new Static widget lifecycle. `test_happy_text_done_renders_markdown` (issue #4) stays but updates its assertions for the new no-prefix Text + label format.
---
## Acceptance
- Issue #3 contract amended in-place per the cli section above.
- Issue #4 contract amended in-place per the tui section above.
- All amended contracts drift-check clean.
- All existing tests + new `CliPresenterState` / `TuiPresenterState`
coverage GREEN under `uv run pytest tests/`.
- `uv run ruff check src/ tests/` clean.
- Boundary smoke `tests/test_no_worldtree_imports.py` still passes.
- Manual smoke: `source env.sh && uv run ratatoskr --new --agent mimir
--send "test"` produces:
- Thinking deltas render as ONE coalesced growing line ending with `\n`
on the first non-thinking event.
- WorkerPhase/TextBoundary/ToolStart/ToolResult lines start with `. `
prefix.
- `[done]` lands on its own line below the assistant text, with `usage
6756 in -> 126 out (...)` and `duration=5.5s` formatting.
- Manual smoke TUI: `source env.sh && uv run ratatoskr --new --agent
mimir` shows the dedicated `Static(id="thinking-current")` widget
visible during thinking, hidden after the turn terminal, with one
closed RichLog entry per thinking run.
- Regression: --send "..." > out.txt continues to write ONLY the
assistant's text content to out.txt (no demoted-telemetry leakage).
## Dependencies
- Issue #3 (`ratatoskr.cli`) — landed on main; this issue amends its
rendering contract in-place.
- Issue #4 (`ratatoskr.tui`) — landed on main; this issue amends its
rendering contract in-place.
- Cross-frontier design pass with eitri-smithy-dev (althing
`01KSBE52YZR5E3SPTKA672JE43`) — settled the 16 confirmed decisions +
4 material divergences baked into this contract.

FN _render_event_to_log(event: Event, *, log: RichLog, raw: bool) -> None
BRIEF: Pure event-to-RichLog renderer. Routes `Text` event deltas (raw text appended to the log) and labels every other Event variant (consistent with cli.py's `_render_event` but writes to a RichLog widget instead of stdout/stderr). The post-Done markdown render is NOT this function's job — it lives in `_stream_turn_worker` so the contract concern (per-event labeling) stays separate from the per-turn concern (post-Done markdown).
PRE: [PRE-001 hard] event is an instance of one of the Event union variants -- assert isinstance(event, (WorkerPhase, Thinking, Text, TextBoundary, ToolStart, ToolResult, Done, Error, Cancelled))
POST: [POST-001 side_effect] for Text events: log received event.content as a streamed delta (no newline appended per delta — RichLog handles chunk-by-chunk display)
POST: [POST-002 side_effect] for non-Text events: log received exactly one labeled line per event
POST: [POST-003 side_effect] Done event renders the same label format as cli.py's `_render_event` (turn_id from sse_id, model, duration_ms, usage); the post-Done markdown render is the caller's responsibility (NOT this function's)
STEPS:
1. [setup, flexibility=prescriptive] Match on type(event)
2. [branch, flexibility=prescriptive] Same case-table as cli._render_event but writing log.write(...) instead of stdout/stderr:
CASE Text: log.write(event.content) (raw text; RichLog handles wrap)
CASE Done: log.write(f"[done] turn_id={event.sse_id.turn_id} model={event.model} duration_ms={event.duration_ms} usage={event.usage!r}")
CASE Error: log.write(f"[error] turn_id={event.sse_id.turn_id} code={event.error_code} message={event.message!r}")
CASE Cancelled: log.write(f"[cancelled] turn_id={event.turn_id} reason={event.reason!r} partial_message_id={event.partial_message_id}")

CASE ToolResult: log.write(f"[tool_result] name={event.name} duration_ms={event.duration_ms} result={event.result!r:.200}")
# Note on {!r:.200}: this is valid Python f-string syntax — `!r` converts via repr(), then `:.200` is the format spec which for strings truncates to 200 chars. The composition yields a repr() that is at most 200 chars long (quotes count). Mirrors cli.py's _render_event for consistency.
CLASS TuiPresenterState # issue #12 amendment
BRIEF: Stateful per-turn presenter for TUI mode. Replaces the stateless `_render_event_to_log` (removed). Owns `thinking_buffer`, `thinking_open`; coalesces thinking-event deltas into per-delta live updates on the dedicated `Static(id="thinking-current")` widget AND one closed RichLog entry per run (two-views-of-thinking decoupling); demotes telemetry events with a `· ` dim prefix on RichLog; Done renders a load-bearing label + Markdown (when not raw); render exceptions degrade to a plain-labeled fallback + `[render_error] <type>` line (NO exception message per INV-009 security).

baseline policy; the initial "scope-add needed" diagnosis was a phantom
ask (see Tried-and-abandoned). The actual lofn fix shipped as issue #5

- Issue #12 code-review consult posted to volva 2026-05-23 (althing
thread `01KSBH8GYH4G3H03T767X613W7`). Reply pending in inbox.
**Outstanding operator-side todos:**
- **Commit issue #12 work** + tag v0.2.0 + push. 9 modified files +
new `12.contract.md` ready.
- **Post-v0.2.0 mimir smoke (the visual one)** — `source env.sh && uv
run ratatoskr --new --agent mimir --send "test"` to eyeball the new
rendering (`. thinking: ...` coalesce, `. worker_phase: ...` demotion,
`duration=5.5s` formatting, `usage 6756 in -> 126 out (...)` shape).
The v0.1.0 mimir smoke confirmed wire-level backwards compat but
did NOT exercise the v0.2.0 rendering.

`RATATOSKR_END_USER_ID="ratatoskr-tui"`). Now unblocked on auth.

## Recent decisions
@@ -117,6 +134,8 @@ decision. Captures rationale that won't be obvious from code alone.
- `[2026-05-23]` **Issue #5 (`--end-user-id`) implemented via TDD.** Small surface change across three modules (sessions, cli, tui): `create_session(client, agent_id, *, end_user_id=None)` widens with optional kwarg; body conditionally adds the field when non-None (INV-002: omitting != sending empty); PRE-003 asserts non-empty. `ParsedArgs.end_user_id: str | None = None` field; `--end-user-id` CLI flag with non-empty validation (mirrors `--send` check). `_amain` and `_resolve_then_run` thread `end_user_id=args.end_user_id` to their `create_session` calls. Post-#6 adjustment: the contract originally named `on_mount` as the TUI threading site, but #6 had moved session resolution to `_resolve_then_run` — same shape, different function. 7 new tests across the 3 modules.
- `[2026-05-23]` **Worldtree-dev consult landed authoritative consumer-API guidance** (althing thread `01KSBARG2B8M8C82H6AJGJWX1B`). Key takeaways shaped follow-on work: (1) `end_user_id` is a free-form partition key for long-term memory + persona/valence state; same value → same partition, different values → fully isolated. For Vuong-debugging-Worldtree the recommended posture is a project-stable default with `--end-user-id` override. (2) No programmatic `requires_end_user_id` discovery on `GET /agents` — "try and react to 422" remains the pattern. (3) Breaking-change #196 LOCKED but not shipped: `subject:{type,id}` replaces `end_user_id` at future v0.22.x or v0.23.0; don't pre-implement. (4) Spec pin (v0.19.0) is 3 minor versions stale (current v0.22.1); none of v0.20.0/v0.21.0/v0.22.0 break ratatoskr's surface but the pin lies about what we're committed to. (5) User-Agent header: send one (`ratatoskr/<version> (vh@phasefinal.com)`). (6) `agents.call:lofn` scope needed for lofn smoke. (7) `GET /agents` requires no special scope; issue #8 unblocked on auth.
- `[2026-05-23]` **Follow-up acted on:** User-Agent header added to both `_amain` and `_resolve_then_run` httpx.AsyncClient constructions (with `importlib.metadata` version lookup + fallback to `0.0.0`); `RATATOSKR_END_USER_ID` env-var fallback added to `_parse_args` (resolution: flag > env > None); env.sh ships `RATATOSKR_END_USER_ID="ratatoskr-tui"` as project-stable default. Original issue #5 posture rejected env-var fallback as "papering over isolation"; revised after worldtree-dev's guidance that the realistic single-operator use case wants partition continuity. Issue #5 + #3 contracts amended in-place to document the env-var fallback. Infra-ops pinged via althing for `agents.call:lofn` scope (broker pattern; they forwarded to worldtree-dev). Three Gitea issues filed: #9 (spec-pin refresh), #10 (subject:{type,id} migration tracking), #11 (AdminEvents pane auth prereq).
- `[2026-05-23]` **Issue #12 (presenter contract semantics amendment) implemented via TDD.** Headline: thinking deltas render as ONE coalesced growing line (CLI) / one closed RichLog entry per run + live Static(id="thinking-current") widget per-delta (TUI), not 50 lines per turn. Introduced stateful per-turn presenters: `CliPresenterState` (cli.py) and `TuiPresenterState` (tui.py), both `@dataclass(slots=True)` with thinking_buffer + thinking_open (+ text_written_since_newline for CLI). Editorial promotion line settled: load-bearing = Text/Done/Error/Cancelled (no prefix); demoted telemetry = WorkerPhase/Thinking/TextBoundary/ToolStart/ToolResult (CLI `. ` ASCII prefix; TUI `· ` Unicode dim prefix). CLI stdout/stderr newline-boundary INV-005: when text was streamed mid-line, flush a `\n` to stdout before writing terminal labels to stderr; `text_written_since_newline = not event.content.endswith("\n")` per Volva F4 fix. Helpers `_format_duration_ms` (`347ms` / `5.5s` / `1.2m` autoscale) and `_format_usage` (`6756 in -> 126 out (6882 total, 0 cached)` with arrow="->" CLI or "→" TUI). Per Vor (eitri-smithy-dev cross-frontier consult, althing 01KSBE52YZR5) + Volva paraphrase (5 contract-text ambiguities all fixed in #12.contract.md). `[create_session]` lifecycle line demoted to `. create_session:` (written directly by `_amain`, bypasses state.render). Old `_render_event` / `_render_event_to_log` functions and their TestRenderEvent/TestRenderEventToLog classes removed (no-backwards-compat rule). Contracts amended: #3 (CliPresenterState block + `_run_turn` thread state + `_amain` create_session demotion + `_format_*` helper blocks), #4 (TuiPresenterState block + `_stream_turn_worker` state construction + `compose` Static widget addition). 39 new tests; 19 obsolete tests removed; net 208 GREEN. v0.1.0 → v0.2.0 (minor; pre-amendment output shape broken intentionally — scripts grepping `[thinking] '` no longer work; that's the intended cleanup). Cross-frontier design pass with eitri-smithy-dev returned 16-of-16 confirmed decisions + 4 material divergences applied (ASCII `· ` factual fix, RichLog-one-entry-per-run vs inline-mirror, presenter-state object vs stateless, "contract semantics amendment" framing not "polish"). Calibration note: eitri-smithy-dev's value here was *architectural* (state-object pattern + chronological-vs-live decoupling) not just *tactical*; the framing rename alone justified the consult. Volva paraphrase round added 5 prose-precision fixes (INV-001 "growing display" semantics, TUI hide mechanism unification, render_error security/readability tension, newline-tracking corner case, [create_session] integration path).
- `[2026-05-23]` **Forward direction: Ratatoskr will require `end_user_id` for EVERY access before too long.** Operator's call. Reasoning: even Tier 1 foundational agents (mimir, all Asgardians) that don't *require* `end_user_id` server-side currently fall back to a `_no_end_user` sentinel substrate partition — effectively pollution from a single-operator-debug-tool's perspective. The right shape is "every conversation has an explicit partition key." `RATATOSKR_END_USER_ID="ratatoskr-tui"` env-default in env.sh is the first step toward that posture; once we've validated the partition-isolation experience, the next move is making `end_user_id` mandatory (probably remove the `None`-default in `_parse_args`, fail-closed with a UsageError if neither flag nor env provides it). Consequence for cross-project asks: declined worldtree-dev's offer to ship `requires_end_user_id: bool` on `AgentInfoResponse` because we'd treat every value as true regardless; the try-and-react-to-422 pattern goes away from our side because we never send a request without the field. File a ratatoskr issue when scheduling the change — touches `_parse_args` validation + `_resolve_then_run` + `_amain` + tests + contract amendments to #3 / #5. Treat as a v0.2.0 minor (breaking: existing `--new --agent mimir` without env or flag would start failing). **Cross-frontier alignment (worldtree-dev ack 2026-05-23, althing 01KSBD9FPMCWJMBXNNS4B3MYBS):** the platform side agrees with this framing — `_no_end_user` is a substrate accommodation for identity-less transports, NOT a consumer model. The fallback's `_is_fallback=True` trap door (#185 INV-185-5/8) "could become operator-controlled later" per worldtree-dev, meaning Worldtree itself may tighten the substrate-fallback path. Ratatoskr's forward posture pre-empts that tightening — moving from "we send end_user_id when set" to "we never send a request without end_user_id" stays consumer-correct regardless of what Worldtree does with the fallback knob.
