<what-to-do>

Interview me relentlessly about every aspect of this plan until we reach a shared understanding. Walk down each branch of the design tree, resolving dependencies between decisions one-by-one. For each question, provide your recommended answer.

Ask the questions one at a time, waiting for feedback on each question before continuing.

If a question can be answered by exploring the codebase, explore the codebase instead.

</what-to-do>

<supporting-info>

## Domain awareness

During codebase exploration, also look for existing documentation:

### File structure

Most repos have a single context:

```
/
├── CONTEXT.md
├── docs/
│   └── adr/
│       ├── 0001-event-sourced-orders.md
│       └── 0002-postgres-for-write-model.md
└── src/
```

If a `CONTEXT-MAP.md` exists at the root, the repo has multiple contexts. The map points to where each one lives:

```
/
├── CONTEXT-MAP.md
├── docs/
│   └── adr/                          ← system-wide decisions
├── src/
│   ├── ordering/
│   │   ├── CONTEXT.md
│   │   └── docs/adr/                 ← context-specific decisions
│   └── billing/
│       ├── CONTEXT.md
│       └── docs/adr/
```

Create files lazily — only when you have something to write. If no `CONTEXT.md` exists, create one when the first term is resolved. If no `docs/adr/` exists, create it when the first ADR is needed.

## During the session

### Challenge against the glossary

When the user uses a term that conflicts with the existing language in `CONTEXT.md`, call it out immediately. "Your glossary defines 'cancellation' as X, but you seem to mean Y — which is it?"

### Sharpen fuzzy language

When the user uses vague or overloaded terms, propose a precise canonical term. "You're saying 'account' — do you mean the Customer or the User? Those are different things."

### Discuss concrete scenarios

When domain relationships are being discussed, stress-test them with specific scenarios. Invent scenarios that probe edge cases and force the user to be precise about the boundaries between concepts.

### Cross-reference with code

When the user states how something works, check whether the code agrees. If you find a contradiction, surface it: "Your code cancels entire Orders, but you just said partial cancellation is possible — which is right?"

### Update CONTEXT.md inline

When a term is resolved, update `CONTEXT.md` right there. Don't batch these up — capture them as they happen. Use the format in [CONTEXT-FORMAT.md](./CONTEXT-FORMAT.md).

`CONTEXT.md` should be totally devoid of implementation details. Do not treat `CONTEXT.md` as a spec, a scratch pad, or a repository for implementation decisions. It is a glossary and nothing else.

### Offer ADRs sparingly

Only offer to create an ADR when all three are true:

1. **Hard to reverse** — the cost of changing your mind later is meaningful
2. **Surprising without context** — a future reader will wonder "why did they do it this way?"
3. **The result of a real trade-off** — there were genuine alternatives and you picked one for specific reasons

If any of the three is missing, skip the ADR. Use the format in [ADR-FORMAT.md](./ADR-FORMAT.md).

ARGUMENTS: looking at the v0.5.0 release notes, **this was never discussed with or approved by me**: [Image #1] -- the adapter manifest still needs a manifest section for digests!! users have no way to guarantee that the session logs of their harness follow any SPT-declared syntax. so SPT needs to accept adapter-declared detection methods for picking up the different entries that go into a digest. --- we also need to ensure that SPT's digest collection follows a running agent thread across multiple sessions. for instance in claude code, the user can `/clear` to start a new session, but that session still belongs to a single live agent. does SPT digest synthesis already account for this per-endpoint session hopping? --- for the (hopefully smaller) milestone this entails, let's discuss the four codebase improvement candidates you raised.

Brandon's flagging a shipped decision he didn't approve, and he's onto something real. Before I grill, let me get precise on two things from the code: (1) what the M9 design *actually* forces an adapter to do (so we argue facts, not the release-note's gloss), and (2) thread 2 — does the digest already follow a live agent across `/clear` session-hops, or not. Thread 2 is answerable from code; I'll answer it rather than ask.

Path A confirmed: `locate_template` is filled with the *current* `session_id` and reads exactly one file. And `info.json.session_id` is a single string. So the digest is structurally **single-session-scoped**. Need the `/clear` re-seed behavior to nail thread 2 precisely.

Found the load-bearing fact for thread 2. `establish_perch` (startup.rs:157-165): a perch's `session_id` is **pinned at first bind and immutable while the owner process is alive** — a bind with a different session_id is *refused* (`held under a different session`). And `fetch_history` Path A fills `locate_template` with that one `session_id`, reading exactly one file.

So a CC `/clear` (same process, new session_id, new JSONL) can't update the perch — the whole log-content pipeline (digest **and** echo-commune **and** resume) stays pinned to the first session. Let me confirm the glossary's terms before I challenge them.

93:**session-invocation declaration** (manifest field, noted for spt-plugin parity):
181:### Endpoint types
231:### Agent endpoints vs Shells
325:**session surface** (library abstraction):
422:**endpoint ID**:
471:**endpoint visibility (per-(endpoint, subnet))**:
588:**endpoint description** (canonical CLI term for the resource-advertisement blurb):
611:**endpoint access whitelist** (distinct from the grant store — the outer reach gate):
=== 'session' defs ===
66:The stable set of `spt.exe <subcommand>` entry points that harnesses bind their own hook systems to. When the harness's runtime emits an event (subagent started, tool just invoked, user typed `/clear`, session crashed), the harness's hook fires a short-lived `spt.exe <subcommand>` invocation that mutates on-disk SPT state (perch registry, spool, etc.). spt-core publishes this surface; harnesses author the bindings.
87:Once-per-session usage/syntax hints, a first-class adapter feature: the manifest's `[hints]` section declares entries of `{keywords (literal default, regex opt-in), text}`; the adapter's user-prompt hook pipes the **full user message** to `spt api hint --session <id>` (stdin) and receives matched hint lines (`keyword hint for SPT adapter <name>: "<kw>"-->{text}`) for its context-injection channel. The daemon keeps a per-session seen-set — each hint fires **once per session** (a `/clear` mints a new session, naturally re-arming) — and emits at most **one hint per message**. **Tiebreak when a message matches multiple hints:** scan in declaration order and emit the FIRST match whose hint this session has not yet seen; if the declaration-order-first matching hint is already seen, fall through to the next unseen matching hint (the once-per-session and ≤1-per-message invariants both still hold). Emit nothing only when every matching hint is already seen. Employing the hook is the adapter dev's choice; profiles override/extend `[hints]` by leaf-replace like any section.
103:**post-spawn seam** — the just-launched binary calls an spt-core command on boot (via the adapter's SessionStart-equivalent hook) to bind itself. Needed because the harness's own session id usually isn't known until after the binary runs. Payload: the harness `session_id` (when binary-generated rather than spt-core-injected); the `parent_pid` (the stable session-binding anchor — see KNOWN-HAZARDS 2.1); an endpoint identity/type confirmation; optionally a local HTTP port the binary listens on (for HTTP-mode input delivery, below); and a **boot nonce** (a generation/boot discriminator so a respawn-after-crash bind can't be confused with a stale duplicate — guards KNOWN-HAZARDS 2.4). The call flips the perch from skeleton → live.
105:**post-spawn is optional only under a strict commitment:** an adapter may forgo post-spawn *only* if it (a) injects the spt-core-generated session UUID at spawn AND (b) guarantees the launched-process pid IS the stable session-binding anchor (no wrapper-script / subprocess pid indirection). If either does not hold, post-spawn must fire to report `session_id` and/or `parent_pid`. UUID-injection alone suppresses only the `session_id` reporting, not the binding.
146:- **`api listen`** — *long-running* relay/poll listener that an adapter-owned (harness-hosted) session owns as a child process; streams the daemon's events to the session's stdout. Distinct from the short-lived `api poll`. This is the heir to today's Monitor-bound `$LIVE start` poll loop.
151:- **`api boundary <clear|compact>`** — context-boundary report; **carries the new `session_id`** (it rotates on `/clear` or `/compact`), so the daemon rebinds the perch to the new session id while keeping the stable identity + `parent_pid` anchor. Authors a **Self-resume commune** (resume the Self session → commune file-drop) rather than a background echo — strong live-context signal at the boundary (see `docs/CONTEXT-MEMORY.md`).
164:1. The harness's SessionStart hook calls **`spt api seed --pid <parent_pid> [session_id, cwd, adapter_name, …]`**. The daemon records an ephemeral in-memory **seed entry** keyed by `parent_pid` — the session details the spt-hosted topology would share directly, minus the not-yet-chosen `live_id`. In-memory (not a file) avoids drive churn and the `$SPT_HOME` resolution nuisance; seeds are consumed within seconds, so persistence across a daemon restart is unnecessary (re-fired on the next SessionStart if needed).
165:2. The agent runs `/spt:live <id>` → the adapter's `$LIVE start <id>` alias = **`$SPT listen <id>`** (= `spt api listen <id>`), invoked via Monitor. It self-discovers its `parent_pid`, the daemon matches the seed entry by that pid (validated against `session_id` to defeat PID-recycling — KNOWN-HAZARDS 5.1), creates/revives the perch binding `live_id` ↔ session details, then enters the long-running relay loop streaming events to stdout.
335:A rolling, human-glanceable view of an endpoint's **recent session activity** — the last ~N user turns (default ~3) plus the agent output between them, with **tool-usage sprints collapsed** to a single entry (e.g. `<endpoint_id> used: **Write** `dir/file.txt` · **Bash** `first ~25 cmd chars` · […]`). Distinct from both the **raw scrollback ring** (unparsed bytes) and full **transcript history** (the conversation behind echo communes/resume): its job is *"what is this agent doing right now, at a glance,"* not conversation replay.
338:- **Topology-independent.** Because the source is logs, the digest works for harness-hosted endpoints too — Claude Code's per-session JSONL is Path A's worked example. Freshness = file-watch + adapter hook nudges; harnesses with no usable logs push entries directly via **`api digest-entry`** (the Path-B-style door). Near-realtime tailing needs an *incremental* normalize story (design-phase concern: Path A's normalize-command was shaped for occasional pulls).


Bigger find — CONTEXT.md:151 already specs the answer: **`api boundary <clear|compact>`** "carries the new `session_id` (it rotates on `/clear`), so the daemon rebinds the perch to the new session id while keeping the stable identity + `parent_pid` anchor." So the *model* already accounts for session-hopping. Question is whether it's built — because the `establish_perch` guard I just read would *refuse* exactly that rotation.

Both questions now answered from the code. Here's where we actually stand before I start grilling you.

---

## Your two concerns — graded against the code

**Concern 1 (manifest needs a digest seam) — you're right, and it's worse than the release note implies.**

The M9 design (my §2 ruling, which — you're correct — you never approved) says: adapter ships a `normalize_command`; its output must *be* the `{role,text,tool}` contract. But that same `[history]` source feeds **two consumers**:
- **echo-commune** pipes records *opaque/verbatim* to a summarizer — it wants rich, full-fidelity records.
- **digest** needs them to *parse* as the contract.

One normalizer can't serve both well. Emit rich records → the digest silently drops every line (`record_to_tagged` = `from_str().ok()`, my Candidate 02). Emit contract records → echo loses fidelity. So your instinct is exact: the digest needs its **own adapter-declared extraction**, decoupled from echo's opaque pass-through. "No digest manifest section" was the wrong call.

**Concern 2 (follow a thread across `/clear` session-hops) — partially handled, with a real hole.**

The *binding* level already handles it. CONTEXT.md:151 specs **`api boundary <clear|compact>`**, and it's **built + tested** (`cmd_boundary` → `resurface_at_boundary`, reporting.rs:42): on `/clear`, the harness fires `api boundary clear --to-session <new_sid>`, the daemon **rebinds the perch to the new session_id while keeping the stable identity + parent_pid**. So your mental model is the designed one — and the glossary already backs it:

> **live agent / endpoint** = stable identity, persists across sessions · **session** = one `/clear`-bounded run, `session_id` rotates.

No term conflict. But here's the hole: the digest's `locate_template` resolves to a **single** `{session_id}` file. After a boundary rebind, it follows the agent to the *new* session — then sees **only** the new session. At the instant of `/clear` the rolling ~3-turn window goes near-empty; the pre-clear activity vanishes. It **follows** the thread but cannot **span** it. The old session's JSONL still exists on disk (CC keeps per-session files) — locate just doesn't reach for it.

---

## The convergence

Both concerns point at the same missing module: a **digest-source declaration in the manifest** that (a) maps the harness's *native* log shape → digest entries (your Concern 1), and (b) can enumerate **multiple session files for one live agent** (your Concern 2). That's a real `[digest]` seam — reversing ADR-0008's "no manifest seam." Worth an ADR when we land it (hard-to-reverse, surprising, genuine trade-off).

This is a milestone, and a contained one. The four candidates fold in as the supporting cleanup (Candidate 01 register-time validation, 02 digest diagnostic, 03 dual-consumer E2E all become *part* of this seam's tests; 04 is orthogonal).

---

I'll grill one question at a time. First fork — it's upstream of everything else (it decides whether `locate` stays single-file or becomes multi-session, which shapes the whole `[digest]` section):

**Q1 — At a `/clear` boundary, what should the digest window do?**

- **(A) Follow-and-reset** — after the boundary, the digest shows only the new session. Simple: `locate` stays `{session_id}`-keyed; a `/clear` is a hard reset of "what's it doing right now." Cheapest. But a glance right after `/clear` shows an empty agent even though it's mid-task on a continued thread.
- **(B) Thread-spanning window** *(my recommendation)* — the ~3-turn window bridges the hop: last turns of session N + first of session N+1 coexist until the old ones age out naturally. Matches "follow a running agent thread." Costs a source model that enumerates an endpoint's recent sessions (newest-first, bounded) instead of resolving one path — which is exactly the `[digest]` detection seam you're asking for, so we're building it anyway.

I recommend **(B)** — it's the whole point of your Concern 2, the files already exist to make it work, and it doesn't actually cost much *given* we're adding the `[digest]` seam regardless. (A) would re-litigate the same gap the moment a frontend renders a live digest pane.

Which way — and do you see `/clear` as a "reset what it's doing" or "same thread, keep glancing"?


with this milestone, let's be sure to update the harness integration checklist in the docs. --- Q1: (B), agree. note that legacy has something like this in the form of `psyches/tracked/agents/<id>/sessions.log`. -clear is more "same thread, keep glancing". though the `clear` action should be distinctive in its representation within the digest.


(B) locked, "same thread, keep glancing," with a **distinctive `/clear` marker** in the digest. And two notes captured: update the harness integration checklist in docs; legacy has a `sessions.log` precedent. Let me mine the legacy shape first (ADR-0001 says copy-verbatim stable sister-project formats), then update the glossary for the resolved decision.

Grep legacy for sessions.log usage

./.planning/debug/doyle-fresh-ctx-after-v1-10-16.md:31:- Phase 24 introduced `src/common/tracked.rs` with `migrate_legacy_if_needed`, `ensure_seed`, `ensure_agent_worktree`, sessions-log writers, and doctor data-source rows.
./.planning/debug/doyle-fresh-ctx-after-v1-10-16.md:122:    5. The next `ensure_seed()` (fired by any tracked-layout call site — pulse, commune, signoff, sessions-log append, doctor, etc.) runs `migrate_legacy_if_needed(seed_existed_before=true)`, sees the freshly-created legacy file, renames it into `agents/doyle/live_context.md`, OVERWRITING the canonical worktree file with the fresh-init skeleton.
./.planning/debug/doyle-sessions-seal-tracked-psyches.md:3:trigger: "doyle sessions log seal failed + empty psyches/tracked dir + missing signoff context (3 symptoms suspected related)"

Note: that placeholder-looking UUID `22222222-...` suggests a test/fallback was used at some prior point, but it IS a row. Sessions.log has 9 total rows, all from a single accumulated window since the last successful seal.

Per-agent worktrees materialized at `psyches/tracked/agents/{id}/` with `sessions.log`, `info.json`, `live_context.md`, `memformat.xml`, `daemon.log`, `.git` worktree-marker file. Bootstrap, `ensure_seed`, and `ensure_agent_worktree` are all working. User's "psyches dir is empty" report was incorrect (likely a `dir` against the wrong path or stale recollection).

./.planning/debug/doyle-sessions-seal-tracked-psyches.md:85:  evidence: Phase 25 is `planning` status per STATE.md (29/29 prior plans complete, Phase 25 not executed). The nested perch (`owlery/doyle/nested/doyle-psyche/`) exists because some Phase 25 paths landed via earlier work, but the sessions.log code path is fully under Phase 24 and uses `psyches/tracked/agents/{id}/sessions.log` — orthogonal to the perch nesting layout.
./.planning/debug/doyle-sessions-seal-tracked-psyches.md:88:- hypothesis: Phase 35 sessions.log sync code is colliding (commit 96e77d0 touched Phase 35 CONTEXT D-02 about sessions.log syncs)

./.planning/debug/doyle-sessions-seal-tracked-psyches.md:97:  implication: Seal logic is correctly invoked. The failure is downstream in `commit_agent_payload` → `git -C agents/doyle add sessions.log` / `git ... commit`.
./.planning/debug/doyle-sessions-seal-tracked-psyches.md:111:  implication: TWO live writer paths exist for wrapper-state. The top-level perch is the path read by the Phase 24 sessions-log emitter. The nested copy belongs to a DIFFERENT psyche-wrapper instance (gen 52 — much older `last_fresh_launch`). One psyche-wrapper process writes to top-level (`perch_dir("doyle-psyche")`), another writes to nested (`nested_perch_dir("doyle", "doyle-psyche")`). They are not the same process.
./.planning/debug/doyle-sessions-seal-tracked-psyches.md:121:  implication: **SMOKING GUN.** Git writes `index.lock` as a coordination sentinel at the start of any index-mutating operation, then renames it to `index` on success. A 0-byte stale lock means a previous `git add` / `git commit` was interrupted (crash, SIGKILL, host reboot, owl.exe handoff mid-commit, etc.) and never cleaned up. Every subsequent `git -C agents/doyle add sessions.log` / `git ... commit` now fails with "Unable to create '.../index.lock': Another git process seems to be running." This is the EXACT error in the seal warning. No actual concurrent git process exists.
./.planning/debug/doyle-sessions-seal-tracked-psyches.md:128:    let path = wt.join("sessions.log");
./.planning/debug/doyle-sessions-seal-tracked-psyches.md:133:    commit_agent_payload(agent_id, &["sessions.log"], &subject)?;     // <-- fails here
./.planning/debug/doyle-sessions-seal-tracked-psyches.md:136:  implication: Failure point is `commit_agent_payload` (which runs `git add` then `git commit`, both blocked by stale index.lock). Because commit returns early with `Err`, the `atomic_write_string(&path, "")` truncation also never runs — so sessions.log keeps growing across gens without rotation.
./.planning/debug/doyle-sessions-seal-tracked-psyches.md:139:  checked: `agents/doyle/sessions.log` content

Most recent row is the 09:11 commune. All entries are from the SAME real wrapper session window (sessions.log is supposed to roll on every boot but hasn't because seal fails on each gen).
./.planning/debug/doyle-sessions-seal-tracked-psyches.md:141:  implication: Sessions.log has been accumulating across multiple `boot`/`pulse`/`commune` triggers because seal-on-boot has failed every time. Tags `doyle-gen-{4,5,6,7,8}` in `tracked/.git/refs/tags/` are from the LEGACY pre-Phase-24 `tracked/.git` repo (also present at `psyches/tracked/.git/` per the comment at `tracked.rs:1317` "Pitfall 6 — Phase 23-era tracked/.git/ preserved in place") — they are NOT Phase 24 seal commits. The Phase 24 seal commits live in `psyches/tracked/seed/` and there are NONE for doyle past whatever last succeeded.
./.planning/debug/doyle-sessions-seal-tracked-psyches.md:162:### Symptom 1 (sessions.log seal failed gen 4 — "Another git process seems to be running")
./.planning/debug/doyle-sessions-seal-tracked-psyches.md:170:Once present, every subsequent `git add` / `git commit` invocation routed through `commit_agent_payload("doyle", &["sessions.log"], ...)` at `src/common/tracked.rs:1262` fails immediately in `git`'s lock acquisition (before any actual index touch). Git emits the verbatim "Another git process seems to be running" message even though no concurrent git process exists.

Legacy `sessions.log` is the **Psyche wrapper's** per-agent generation log (`psyches/tracked/agents/<id>/sessions.log` — JSONL `{ts, session_uuid, trigger}`, git-sealed per gen). Not a digest mechanism, but it proves the pattern: **a per-agent append-only ledger of session boundaries.** That's the heir we want — `api boundary clear` already fires at the hop; it just needs to *record* the new session_id into a per-endpoint **session ledger** so the digest source can enumerate "last K sessions, newest-first" to span the window. The `/clear` marker = a boundary entry the projection inserts where the ledger shows a transition.

Let me capture Q1's resolved concept in the glossary precisely, then continue.

Edit

- **Two access modes.** **Snapshot pull** — `spt endpoint digest <[subnet:]id[@node]>` returns the current structured buffer

- **Thread-spanning across session boundaries.** A live agent's identity persists across many harness *sessions* (a `/clear` or `/compact` rotates the harness `session_id` — see `api boundary` / **post-spawn seam** — while the endpoint identity and `parent_pid` anchor hold). The digest follows the **agent thread**, not a single session: its rolling window may bridge a boundary (the tail of session N and the head of session N+1 coexist until the old turns age out), so a glance right after a `/clear` still shows the agent mid-thread rather than empty. A session boundary is itself **represented distinctively** in the digest (a visible boundary marker, e.g. a `/clear` divider), so a reader sees that context reset *there* without losing the thread. (Heir to the sister project's per-agent `sessions.log` boundary ledger.)

Glossary updated for Q1 (thread-spanning + distinctive `/clear` marker, with the legacy ledger heritage noted). I left the "no manifest seam" line (341) intact — that's the thing this milestone reopens, and I won't pre-write the reversal until its shape is decided.

Next fork is the heart of your Concern 1: *how* the adapter declares digest detection. That hinges on whether one harness log line maps to one digest entry or many — let me look at a real Claude Code JSONL record so I recommend against reality, not a guess.

shape agent-name -> none
shape agent-setting -> none
shape queue-operation -> none
shape attachment -> none
shape user -> str
shape assistant -> ['thinking']
shape last-prompt -> none

Grounded now — and the real CC log is decisive. A sample session JSONL has **9 top-level `type`s**, most of them noise to filter out (`custom-title`, `agent-name`, `agent-setting`, `queue-operation`, `attachment`, `last-prompt`, `mode`), plus the two that matter:

- `user` → `content` is sometimes a bare **string**, sometimes a **list** (tool_results)
- `assistant` → `content` is a **list mixing `thinking` + `text` + `tool_use` blocks** → one line becomes *multiple* digest entries, and `thinking` must be dropped

So **one harness log line ≠ one digest entry**, and extraction means: filter types, walk a content array, branch per block, skip thinking, split text from tool_use. That kills the clean-declarative dream.

**Q2 — How does the adapter declare digest detection/extraction?**

- **(A) Declarative field/match map** in `[digest]` (jsonpath-lite per role). Inspectable, validatable at `adapter add`, no binary. **But** the real CC shape above needs array-walking + per-block branching + skip-thinking — a flat map can't express "one line → text + N tools," and a DSL that can is a reinvented programming language. Too weak for the actual target.
- **(B) Imperative digest extractor** *(my recommendation)* — `[digest]` declares a digest-specific command (separate from echo's `normalize_command`) that emits the `{role,text,tool}` contract. The adapter already writes code; a ~30-line extractor handles CC's nesting trivially. This is the corrected version of the "approach C" I wrongly rejected in M9 §2 — I rejected it because I thought echo's one normalizer could serve the digest too; your dual-consumer point is exactly why it can't.
- **(C) (B) + keep `api digest-entry` push** as the always-available escape hatch for adapters that'd rather push from a hook than declare a source. (Already built in M9.)

I recommend **(C)**: imperative extractor as the declared path, push door as the fallback. It gives you the adapter-declared detection you asked for, decouples digest extraction from echo's opaque pass-through (one source file, two extractors), and matches what real harness logs actually demand.

The one thing **(B)/(C)** can't do is validate the extractor's *output* at register time — which is precisely why Candidate 02 (runtime skip-diagnostics) becomes load-bearing here rather than optional.

Agree on (C)? And: should declarative (A) survive as a convenience for simple/well-shaped logs, or do we refuse to ship a half-power DSL and make imperative-or-push the only two doors?

(Background legacy-search task finished — already consumed its output earlier. Nothing to do.) Awaiting your Q2 answer.


agree with (C). -note we should also provide an api command/tool that helps developers proof their digest command's output, and surfaces any issues with it. --- i think foregoing (A) makes sense, as anyone who could conform to that format could just as easily bake `api digest-entry` into their custom endpoint binary, or build (B) for their adapter.


(C) locked, (A) dropped. Three things captured:

1. **`[digest]` seam = imperative extractor + `api digest-entry` push door. No declarative DSL.** Your reason — anyone who could hit a declarative format could just bake `api digest-entry` into their binary or write the extractor — is exactly the kind of rationale a future explorer needs so nobody re-proposes the DSL. That's going in the ADR.
2. **A digest-proof dev tool** — call it `spt adapter digest-proof <adapter> [--sample <log>]`: runs the declared extractor over a real sample, prints the parsed `{role,text,tool}` records + the rendered digest, and flags every dropped/malformed line with the reason. It's the dev-facing twin of Candidate 02's runtime skip-diagnostics — same diagnostic engine, one surface for the author at build time, one for the daemon at runtime.
3. This reverses **ADR-0008**'s "no manifest seam / `[pty_digest]` removed, nothing replaces it." That's a real reversal of a published, adapter-facing decision → **I'll draft an ADR** ("digest rides an adapter-declared `[digest]` extractor, not a fixed contract over `[history]`") once the section shape below lands, so it captures the whole decision in one go. Good?

**Q4 — Where does the extractor live: a new `[digest]` section, or an extension of `[history]`?**

The forcing constraint: the digest must read the **last K session files** (thread-spanning, Q1), while `[history]`/echo reads exactly **one** (the current `session_id`). They diverge on source cardinality, not just extractor.

- **(A) Extend `[history]`** — add a `digest_extract` command alongside `normalize_command`, reuse its `locate_template`. Smallest surface. **But** `[history]`'s locate resolves one file; bolting multi-session enumeration onto it muddies a seam that echo wants to stay single-session. The two consumers get tangled again — the exact thing we're separating.
- **(B) Separate `[digest]` section** *(my recommendation)* — mirrors `[history]`'s strategy enum (`locate_normalize` / `fetcher` / push) but is contract-typed and **session-spanning-aware**: spt-core enumerates the endpoint's recent sessions from the ledger, runs the adapter's extractor per file, concatenates with boundary markers. It may *reference* `[history]`'s locate pattern to avoid repeating the path, but owns its own cardinality + extractor. Clean separation: `[history]`→echo (one session, opaque), `[digest]`→digest (K sessions, contract).

I recommend **(B)** — the source-cardinality split is real and permanent; forcing it through `[history]` re-tangles the dual consumers we just paid to separate. The cost is one more manifest section, which is honest surface for a genuinely distinct source model.

Agree on a separate `[digest]` section? And — do you want the digest's source to be able to differ entirely from `[history]` (a totally separate file/command), or should it be constrained to "same logs as `[history]`, different extractor + spanning" to keep adapters simple?


-i want to suggest that we drop "digest is last 3 turns" as a requirement, and leave the quantity of digest output as open to the adapter devs' preference. -another suggestion: digests include mirrors of spt's context-to-agent payloads. so things like session-start psyche downloads, echo commune mirrors-to-agent, and incoming owl messages can all be surfaced and explored within a digest. a digest GUI would likely collapse these + user can opt to expand them to understand what they say. <-- this comes up now because psyche downloads and echo commune mirrors would be helpful context for actual echo communes to effectively build their context deltas. 3. agreed, good. Q4: agree with your rec. -i'm leaning "same logs, different extractor", but use your best judgment.


Two strong new ideas. Before I bank them, let me verify the load-bearing fact for Suggestion 2 — whether records carry timestamps (you can't interleave agent-activity with spt-injections without an ordering key) — and where spt's injection points actually are.


d=$(ls -dt /c/Users/decid/.claude/projects/*/ 2>/dev/null | head -1); f=$(ls -t "$d"*.jsonl 2>/dev/null | head -1); echo "=== CC record keys (user/assistant) + has timestamp? ==="; head -200 "$f" 2>/dev/null | python -c "import sys,json
seen={}
for ln in sys.stdin:
    ln=ln.strip()
    if not ln: continue
    try:o=json.loads(ln)
    except:continue
    t=o.get('type')
    if t in('user','assistant') and t not in seen:
        seen[t]=sorted(o.keys())
for t,k in seen.items(): print(t,'keys:',k)
" 2>&1 | head

Check CC record timestamp + keys

-i want to suggest that we drop "digest is last 3 turns" as a requirement, and leave the quantity of digest output as open to the adapter devs' preference. -another suggestion: digests include mirrors…


Verified. CC records carry `timestamp` + `sessionId` + `uuid`/`parentUuid` on every line — so interleaving agent-activity with spt-injections by time is feasible. And the injection taps you named are real modules: psyche download → `psyche.rs`, echo mirror → `echo.rs`, owl messages → the spool/`ingest.rs`. Both suggestions are physically supported.

**Suggestion 1 (drop fixed ~3) — accepted.** My call on the shape (flag if wrong, not asking): window depth becomes an **adapter-declared default in `[digest]`**, **consumer-overridable at pull/subscribe** (a GUI can ask for more/less). I'd extend the same treatment to arg-truncation and sprint-collapse — they're all presentation knobs; adapter sets sane defaults, consumer overrides, spt-core ships fallbacks if silent. Extraction stays the adapter's; *how much* is shown stops being spt-core dogma.

**Q4 tail — my judgment:** default to "**same source files as `[history]`** (reference its locate pattern, DRY), different extractor + spanning," but leave an **own-source escape hatch** in `[digest]` for a harness whose digest-relevant data lives elsewhere. Simple by default, not boxed-in.

**Suggestion 2 (digest mirrors spt→agent context payloads) — this is the strong one, and the rationale is right:** an echo-commune building its *next* delta needs to know what context the agent was already fed (psyche download, the last echo mirror, owl messages) so it doesn't re-summarize it. That closes a real loop. It also reframes the digest from "what the agent *did*" to "the agent's recent context — what it did **and** what it was fed," as one time-ordered, collapsible timeline.

But it's also the **scope-expander** for your "hopefully smaller" milestone. It adds: a second entry *origin* (spt-owned injections, not from the harness log), a contract change (a `ts` ordering key + a collapsible **context-injection** category with subtypes `psyche_download | echo_mirror | owl_message`), a merge engine (extracted records ⋈ digest.log by `ts`), and taps in psyche/echo/spool to append those entries. The clean mechanism: **spt appends its injection entries to the endpoint's `digest.log`** (reuse the M9 Path-B sink — spt just becomes an internal producer), and the projection merges both origins by timestamp.

**Q5 — How much of Suggestion 2 lands in this milestone?**

- **(i) All of it** — data model + taps + GUI-collapse semantics + the echo-reads-digest feedback loop. Biggest; pulls in surfaces (GUI, echo-delta) that don't exist yet.
- **(ii) Data model + taps now, consumers deferred** *(my recommendation)* — expand the contract (`ts` + context-injection category), build the two-origin merge, and tap psyche/echo/spool to append injection entries to `digest.log` this milestone. **Defer** the GUI collapse/expand UX and the echo-reads-digest delta loop to the milestones that own those surfaces. Rationale: the contract + merge are the parts that are *expensive to retrofit* (a second breaking contract change later is worse than one now), while the consumers can't be exercised until their surfaces exist — same deferral logic we used in M9.
- **(iii) Defer all of Suggestion 2** — ship `[digest]` extractor + spanning + proof tool only; add context-mirroring as a fast-follow.

I recommend **(ii)**: get the contract and the merge right once, now; defer what has no consumer yet. It keeps this milestone bounded to "the digest seam + its data model" without building phantom UIs, and it means the echo-feedback loop later is pure consumption of a model that already carries the data.

Which scope — and if (ii), do you agree the spt-injection entries should ride the existing `digest.log` sink rather than a new ledger?


sugg1: agree. Q4 tail: agree. -sugg2: agree. Q5: agree with (ii). -yes, agree


All locked. The design is coherent now — let me capture it in the glossary (overdue, decisions are firm) and draft the ADR you greenlit. Reading the current digest entry to rewrite it precisely.

A TUI's PTY stream is a *rendering protocol*, not a content log: scroll/resize trigger full repaints (duplicate content), and semantic turn boundaries drown in repaint soup. The split: **render surfaces read the PTY** (the R-TERM raw byte ring, unchanged); **content surfaces read the logs**. The digest is a rolling tail-projection of the **same normalized history the echo-commune consumes** (history subsystem Path A locate+normalize / Path B native store) — one pipeline, two consumers. The presentation formula (N-turn window, collapsed sprints, ~25-char arg truncation as spt-core presentation) is unchanged from the original conception.
338	- **Topology-independent.** Because the source is logs, the digest works for harness-hosted endpoints too — Claude Code's per-session JSONL is Path A's worked example. Freshness = file-watch + adapter hook nudges; harnesses with no usable logs push entries directly via **`api digest-entry`** (the Path-B-style door). Near-realtime tailing needs an *incremental* normalize story (design-phase concern: Path A's normalize-command was shaped for occasional pulls).
339	- **Thread-spanning across session boundaries.** A live agent's identity persists across many harness *sessions* (a `/clear` or `/compact` rotates the harness `session_id` — see `api boundary` / **post-spawn seam** — while the endpoint identity and `parent_pid` anchor hold). The digest follows the **agent thread**, not a single session: its rolling window may bridge a boundary (the tail of session N and the head of session N+1 coexist until the old turns age out), so a glance right after a `/clear` still shows the agent mid-thread rather than empty. A session boundary is itself **represented distinctively** in the digest (a visible boundary marker, e.g. a `/clear` divider), so a reader sees that context reset *there* without losing the thread. (Heir to the sister project's per-agent `sessions.log` boundary ledger.)
340	- **Two access modes.** **Snapshot pull** — `spt endpoint digest <[subnet:]id[@node]>` returns the current structured buffer (a Shell/CLI/GUI on-demand render; feeds the frontend's "latest session output" pane; a Gateway's agent-window). **Structured-delta stream** — a subscriber (live Shell pane, GUI, Gateway) receives only *changes* (new turn, new tool entry, collapse update), keyed to log records, for resource-efficient near-realtime reflection. **Access is address-gated** — fetch/subscribe is allowed for anyone who can address the endpoint (visible + resolvable per the resolution policy), the same gate as messaging.
341	- **"Option (C)" logging surface:** the digest may also be *persisted* (opt-in per-endpoint) as a coarse activity log appended to the native history store (Path B), on-boundary or periodic — off by default.
342	- **Source mechanism reconciled (M9, ADR-0008 amendment made real):** the PTY-parse engine is **retired** — the digest is now an **on-demand projection** of the endpoint's normalized records (`spt-term::projection` over the published digest-record contract; `spt-daemon::digest::project_endpoint_digest` resolves the `[history]` source or the `api digest-entry` `digest.log` sink). No manifest seam (`[pty_digest]` is gone); the digest rides `[history]`. **Deferred (tracked, no consumer yet):** the *autonomous file-watch freshness* nudge and the Option-C persistence re-home land with the consuming-frontend milestone (Shell M10 / GUI pane) that actually reads the live stream — today the delta-stream contract ships and its deltas are driven by pulls / `api digest-entry` pushes.
