From b6eb083e0838db1a80632ff43921917a2b21a769 Mon Sep 17 00:00:00 2001 From: Taras Mankovski Date: Mon, 19 Oct 2026 05:44:01 -0400 Subject: [PATCH 1/2] =?UTF-8?q?=E2=9C=A8=20Read=20a=20failed=20entry's=20s?= =?UTF-8?q?aved=20evidence=20from=20the=20Sidekick=20(#932)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit An entry that failed with nothing printed could not be explained. The only read a reply had was its output, so an entry whose nine agent turns ended with a refusal — and whose output was empty because every turn captured its reply — answered with an empty window and nothing else. What it ran, what it asked, what came back and where any of that is in the file were all in the journal and reachable by nothing. Four bounded reads answer those four questions: ```xmd ``` Journal locates evidence and Prompt reads the selected turn, which is why neither carries the other's body. A Journal page states the entry's complete saved failure, how its turns ended, and one record per saved event — marker, type, name, status, position, prompt number and agent, and no reply, request, result payload, checkpoint or stack. **Selectors and windows resolve once and are stated absolutely.** `entry` and `prompt` are nonzero whole numbers; a positive entry number is admission order and a positive prompt number is a saved sequence plus one, so a turn the file never saved refuses rather than being renumbered into its neighbour. Text windows count Unicode code points and default to 4096, Journal counts records and defaults to 20, and every `previous`/`next` is either null or the complete arguments of the read beside it — the resolved numbers, an absolute offset, the requested limit and the same Prompt field. A continuation followed after another entry has been admitted still reads the entry it was about. **Absence, emptiness and refusal are three answers.** A completed turn's error is `text: null`; a turn that saved an empty reply is `""`; evidence the history does not hold refuses, and the refusal is that control's outcome with the response going on. Entry status and `promptStatus` stay separate, so a turn that returned parseable JSON and ended failed is failed. **Cold reads are passive.** Terminal evidence decides an entry's status even while its task unwinds; without one, only the entry this process is printing is running and any other is unfinished, with an empty output window rather than an invented one. No read opens an entry, resumes one, waits for one, executes source or reaches an entry's provider. **Delivery is ordinary.** Each read answers with its page object: `as` binds it by reference, an uncaptured read renders nothing, and the same page goes back as the read's own designated result either way. Only an explicit `` is chat. A submission's receipt now names the admitted entry by that number and points a completed entry at `` and a failed or cancelled one at ``, because an entry that failed may have printed nothing. **What is intentionally unchanged.** Four production files move: `repl/model.ts` gains detached, deeply frozen per-record metadata formed inside the existing validated projection; private `sidekick/entry-inspection.ts` holds the pure selectors, windows and page builders; `sidekick/requests.ts` answers each read from one acknowledged head and one printing fact; and `sidekick/controls.ts` declares the four controls and designates them. Raw `DurableEvent`s still terminate at the model. No new persistence, index, cursor, ownership or recovery service, generic journal browser, Query dependency or automatic feedback mechanism. `REPL.EntryOutput`'s historical designation, its renderer and `output.ts`'s legacy types are untouched, and a chat that already holds one of its results still reads as the window it was. Evidence, all on this tree. The fixture under `packages/cli/tests/fixtures/repl/issue-932/` is bytes a real run left behind — `produce.ts` drives the production session, entry executions, canonical Prompt path and paired storage with the scripted provider, and its receipt states what it holds and the one machine-specific string substituted out of it. - `deno task test packages/cli/tests/repl-model.test.ts packages/cli/tests/repl-sidekick-controls.test.ts` — 15 passed. One record per saved event with semantic outcomes and no payload retention; relative reads pinning their continuations across a later admission; Journal paging to the final close; defaults, tail, negative, clamped and beyond-end positions; canonical ordering over a resequenced copy of real records; the null, empty, missing, zero, fractional, unknown-field and bad-limit boundaries; and all four mounted controls over a cold unfinished prefix with every execution hook set to fail if reached. - `deno task test packages/cli/tests/repl-sidekick-journey.test.ts packages/cli/tests/repl-sidekick-recovery.test.ts packages/cli/tests/repl-sidekick-output.test.ts` — 22 passed. One real inspection exchange over a run-produced saved failure, with the entry file byte-identical afterwards; capture, identical feedback with and without `as`, Output-only chat and ordinary refusal delivery; the first turn being told the four names and ``; a scripted agent reading the shipped chapter and following it; and a saved `REPL.EntryOutput` pair still rendered by its own renderer. - `deno task test packages/cli/tests/repl-sidekick-presentation.test.ts` — 22 passed, including the receipt rows that submit from a screen frozen at an earlier recorded position. - `deno task test packages/cli/tests/repl-forms.test.ts packages/cli/tests/repl-source-reading.test.ts` — 14 passed, the two hand-built `ReplEntry` constructors the new member reached. - `deno task lint` and `deno task check` — exit 0.

Journal +locates and Prompt reads, which is why neither carries the other's body — a +record states a turn's number, its kind, its status and where it was written, +and never a reply, a request, a result payload, a checkpoint or a stack. + +`entry` and `prompt` are nonzero whole numbers. A positive entry number is +immutable admission order counting from one, and a positive prompt number is a +saved turn's own sequence plus one rather than its position in the list, so two +turns that finished in the order their providers answered keep the numbers +their records state and a number no turn saved refuses rather than being +renumbered into its neighbour. Omitted and `-1` are the latest, and a further +negative counts back from it. Each selector resolves once, when the read +happens. + +Text windows count Unicode code points and default to 4096 of them; Journal +counts records and defaults to twenty. Source and Prompt start at the +beginning. Output's omitted offset is the last window, which is what a reader +of output wants, and an explicit zero is the beginning, which omission cannot +express. A negative offset counts back from what is available and clamps there, +and a positive one past the end stays where it was asked for and answers with +an empty window. A limit is a positive whole number with no maximum of its own, +and what comes back is bounded by the evidence. Every page carries `previous` +and `next`: either null, or the complete arguments of the read beside it, with +the entry and prompt stated as the numbers they resolved to, an absolute offset, +the limit that was asked for and the same Prompt field. A continuation followed +after another entry has been admitted therefore reads the entry it was about. + +A page states the entry's status and, for a Prompt read, the turn's own +separately. An entry is completed, failed, cancelled, running or unfinished; a +saved turn is completed, failed or cancelled, and a turn that returned +well-formed text and ended failed is failed. A turn that saved nothing for the +field being read answers `text: null` with no window either side of it, which +is a different answer from the empty string a turn that saved emptiness gives. +Evidence the history does not hold refuses, as does a zero, fractional or +out-of-range selector, an unknown field and a limit that is not a positive +whole number; a refusal is that operation's outcome and the response goes on. + +Terminal evidence decides an entry's status even while the task that produced +it is still unwinding. Without one, the entry this process is executing is +running and any other is unfinished, so a cold reader of an interrupted history +is told it is unfinished rather than that it is still going. Output is the +retained terminal output where there is one, the text this process has observed +for exactly that entry where there is not, and an empty window otherwise — +nothing invents output a cold reader cannot have. These reads take the +acknowledged head whatever position, scope or tab the screen is on, and they +open no entry, resume none, wait for none, execute no source, reach no entry's +provider and change nothing they read. + +A successful read answers with its page object. An ordinary `as` binds that +object, an uncaptured read renders nothing, and the page goes back to the +conversation as the read's own result either way — capturing one does not +switch its feedback off.

The number is the admitted entry's, whatever entry or +recorded position the screen is showing. + +These reads are of the validated journal projection and of this process's own +observed output, and of nothing else. They reach no provider session file, and +the retained publication, secret and persistence protections stand in front of +anything a page carries.

No production path, protocol, storage, index or recovery machinery is added, and no settled contract moves. **The read the four replaced is retired from admission, not from history.** `sidekickObservations()` no longer offers `REPL.EntryOutput`, so the capture never seals it and a response written now that names it is refused before any control runs. Everything that reads a *saved* result stays exactly as it was: the name keeps its `DESIGNATED` membership, `feedback.ts` keeps its case, `renderRead` keeps its wording, and `output.ts`'s reader and types are untouched — a conversation reopened from a chat holding that control's own pairs is still told what its history says it asked for. Current executable admission and the decoding of a retained result are separate responsibilities, and only the first one moved. The active response examples and tests move to `` and its page semantics; the direct legacy reader suite and the saved-pair compatibility row are unchanged. **A failure released while an earlier position is selected still names its own entry.** The receipt rows that existed submitted from the live head, including the one that reopens at a recorded position and goes back live first, so none of them delivered a receipt while something else was selected. The new presentation row admits the failing entry at the head, holds its outcome inside the host before it can be appended, freezes the screen at the first entry's recorded outcome while it waits, and only then releases it. The screen is still frozen when the receipt is composed, and both the shared renderer and the retained feedback name `entry={3}` with the exact Journal instruction and neither earlier entry. **A captured control-only read is the third E5 case.** The existing exchange read uncaptured, then captured and published through `` inside Output. It now reads a third time with `as="page"` and no Output at all: the page feedback is byte-identical to the other two, the response declares no output region, and the chat holds it as the reply it was with nothing to say. The fixture's chat half is pinned rather than regenerated. It holds a genuine `REPL.EntryOutput` pair that a corrected ceiling cannot produce, so `produce.ts` now writes the entry half alone and `RECEIPT.md` states each half's provenance separately, names the pre-retirement commit the chat half was taken at, and records the exact recipe for reproducing it there. Its bytes and digests are unchanged: `entries.jsonl` `981217b8…`, `sidekick.jsonl` `fbd0175e…`.
