## F-001 — Harness hook-wiring contract incomplete for a Claude Code adapter

**Reported:** 2026-06-14 to doyle (owl). **Status:** awaiting ruling / docs fix.

**What IS published (sufficient):**
- `harness-contract/api.md` — the full `spt api` primitive surface: `seed`, `listen`, `bind`,
  `boundary`, `session-end`, `shutdown`, `state`, `echo-gate`, `presence`, `driven-by`, `poll`,
  `history-log`, `worker-start/poll/stop`, `bind-shell`, `emit`, `owner-shutdown`, `capability`.
- `harness-contract/install-on-demand.md` — install-on-demand bootstrap, exact `sh` + `ps1`
  snippets, canonical installer URLs, env-var customization. **Fully buildable.**
- `harness-contract/integration-checklist.md` + `manifest.md` map: SessionStart →
  `api seed --pid {parent_pid} --session-id {session_id}` then `api listen <id>`; Idle →
  `api state idle|busy`; PreCompact/clear → `api boundary clear|compact <id> --to-session-id <sid>`;
  teardown → `api session-end <id>` / `api shutdown <id>`.

**The gaps:**

1. **Hook-event → `spt api` mapping is incomplete.** No published mapping for **UserPromptSubmit**,
   **PreToolUse**, **SubagentStart**, **SubagentStop**. (`worker-start/stop` exist but are not tied
   to the Subagent hook events.)
2. **Manifest `[hooks.*]` vs harness-native hook config is unspecified.** `manifest.md` declares
   hooks as `[hooks.<event>] fires="api ..." reads=[...] can_inject=bool`, with spt-core performing
   `{key}` substitution from `reads`. It is **silent** on whether spt-core *materializes* the
   harness-native config (Claude Code `hooks.json`) from the manifest, or the adapter author
   hand-writes `hooks.json` that shells out to `spt api`. These imply different substitution models:
   Claude Code delivers hook data as JSON on **stdin**, but the manifest model is spt-core-side
   `{placeholder}` fill — so if `hooks.json` is hand-written, it is unclear who fills
   `--pid {parent_pid}`. (Also reframes the `SCOPE.md` assumption "the plugin ships a `hooks.json`
   calling `spt api`" — it may instead be manifest-declared + spt-materialized.)
3. **Injection mechanism is undocumented.** `can_inject` + an `[inject]` section (methods
   `pty`/`hook`/`relay`/`http`) exist, but there is **no technical detail** on how an adapter emits
   `additionalContext` back through the hook channel. Blocks (a) general mid-session message
   delivery on a prompt/tool hook, and (b) this project's **UPS-injection** skill-instruction design
   (`docs/adr/0001-*`) specifically — it cannot be validated against the public surface until this
   is documented.

**Impact (as first reported):** SessionStart / Stop(idle) / SessionEnd / boundary are buildable now.
UserPromptSubmit + PreToolUse + Subagent wiring + the entire injection path were *thought* blocked.

### Resolution (2026-06-15 — converged with doyle, grounded in `CONTEXT.md`)

The boundary canon (`CONTEXT.md` L52/L181/L112/L149/L137) re-frames F-001: **spt-core is
harness-independent and supplies the agnostic `spt api` primitives + their I/O format; the adapter
authors the harness-specific wiring + output-formatting.** So most of F-001 is **adapter-authoring
work (ours), not an spt-core gap**:

- **Gap 1 (CC-event → api mapping) — OURS, closed.** Which CC hook drives which `api` primitive is
  adapter glue (L181). Owned mappings: SessionStart → `api seed` (+ env aliases); `/sptc:ready|live`
  → `api listen <id>` (the blocking poll loop — *not* SessionStart, which must not block); Stop/Idle
  → `api state idle|busy`; PreCompact/clear → `api boundary`; SessionEnd → `api session-end` /
  signoff → `api shutdown`; SubagentStart/Stop → `api worker-start`/`worker-stop`; UserPromptSubmit
  → `api poll`; **PreToolUse out-of-scope v1** (UPS covers delivery). See `docs/adr/0002-*`.
- **Gap 2 (medium) — OURS, closed.** The `sptc` plugin **hand-writes** its CC `hooks.json` shelling
  `spt api`. spt-core materializing a CC `hooks.json` would violate L52/L181 — it correctly doesn't.
- **Gap 3 (injection HOW) — OURS, closed.** `api poll` emits message frames to **stdout** by design
  (L149) — that IS the hook-injection delivery path; routing/formatting that stdout into CC's
  `additionalContext` channel is adapter glue (L112). The earlier "`can_inject`/`[inject]`
  method-discard is dead code" alarm is **retracted** — it is M2a roadmap staging (stdout/hook only
  now; PTY at M3), and `can_inject` drives the *built* echo-gate/relay fallback (L137) for hooks that
  cannot inject (e.g. CC Stop).
- **CC param-sourcing** ({parent_pid}/{session_id}) — OURS: read off the CC hook-input schema
  (`session_id` is a common stdin field; pid via the hook process). Not an spt-core concern.

**Residual spt-core item (doyle owns; non-blocking):** publish the **agnostic primitives** to the
adapter-facing docs-site — specifically `api poll`'s **emit frame format** (the frame we parse +
format for CC) and the **substitution-key catalog** (currently code-only). doyle verifies against
`CONTEXT.md`/ADRs then propagates (no new design). We will report the **observed** `api poll` frame
format so the publish can confirm-match. Until published we may rely on observed behavior of the
public binary (observable behavior = public surface).

## F-002 — `api poll` (agent path) has no inter-frame delimiter — multi-message drains unsplittable

**Reported:** 2026-06-15 to doyle. **Status:** open — **spt-core CODE gap** (not docs); doyle has
raised the framing as a contract decision to the operator.

**The gap (confirmed from source by doyle):** the **agent** `api poll` path emits each drained
message with `print!("{msg}")` (`delivery.rs:192`) and `format_row` adds **no trailing newline**
(`spool.rs:91-97`). So a multi-message drain **concatenates frames with nothing between them**.
Combined with the frame format (anonymous senders emit a **bare body**, and bodies may be
multiline), a multi-message `poll` stdout is **genuinely unsplittable** — there is no delimiter to
parse on. Tell that this is a rough edge, not intent: the **shell** drain (`cmd_poll_shell`,
`delivery.rs:169`) uses `println!` (newline-framed); only the agent path omits it. The framing is
unspecified in `CONTEXT.md` / `docs/api.md`.

**Impact / our handling:**
- **Single-message poll = unambiguous, works now** — `__REPLY_TO__:<id>\n<body>` or bare body.
- **Multi-frame splitter is HELD** — we do not assume a delimiter that does not exist. The
  UserPromptSubmit wrapper surfaces whatever `poll` returns: a single frame is cleanly per-sender
  formatted; a (rare) concatenated multi-drain degrades to a surfaced-but-unattributed blob rather
  than a parser guessing boundaries.

**Resolution (spt-core, doyle):** a self-delimiting emit on the agent path (length-prefix or a
record separator — plain newline is insufficient given multiline bodies). When it lands, the emit
becomes parseable-for-N and doyle publishes the canonical framing; we then finalize the multi-message
parser. Our throwaway-session byte-capture confirms both the current concatenation behavior and the
fixed framing post-change.

Edit

**Resolution (spt-core, doyle):** a self-delimiting emit on the agent path (length-prefix or a
record separator — plain newline is insufficient given multiline bodies). When it lands, the emit
becomes parseable-for-N and doyle publishes the canonical framing; we then finalize the multi-message
parser. Our throwaway-session byte-capture confirms both the current concatenation behavior and the
fixed framing post-change.

**Resolution — RESOLVED-BY-DESIGN (ADR-0020, operator-ruled 2026-06-15):** the framing question is
settled, more cleanly than a delimiter patch. The **canonical format at every surface — including
`api poll` — is the `<EVENT type="msg" from="<sender>">body</EVENT>` envelope** (`spt-proto::event`,
the ADR-0001 grammar the live listener already emits). `__REPLY_TO__` was a **mis-elevated relic**
(wrongly frozen as the "stable wire format" during the clean-room port) and is being **deleted from
spt-core**. The `<EVENT>` envelope is **self-delimiting**, so multi-message drains split cleanly on
`</EVENT>` — no delimiter needed, and the F-002 multi-frame hold is **lifted**.

- **Our parser** now targets `<EVENT>` (the `from` attr → `<sptc_messages from="…">`, `<br>` →
  newline, entity unescape with `&` last) — exactly the live-agent body-parsing rule. See
  `render_frames` in `plugin/sptc/hooks/_common.sh` + `tests/hooks-parse.sh` (multi-message covered).
- **Transitional (impl pending, spt-core side):** the refactor that makes `api poll` actually *emit*
  `<EVENT>` (`REQ-MSG-ENVELOPE`) is scoped in ADR-0020 but **not yet built** (multi-crate:
  spt-store/spt-msg/spt/spt-daemon/spt-live). The current 0.6.0 binary still emits the `__REPLY_TO__`
  relic at the poll surface. We therefore build for canonical `<EVENT>` but do **not** validate
  against current poll output; doyle pings when the refactor lands, and our throwaway byte-capture
  then confirms `<EVENT>`.


<owl_messages>
<owl_message from="doyle" priority="high">Parse contract — both answered (decided the poll surface deliberately; folded into ADR-0020 Decision §1):

Q1 — ONE <EVENT> per line at poll: YES. Each message = one whole single-line `<EVENT type="msg" from="<sender>">body</EVENT>`, body `<br>`-escaped (interior newlines never break the envelope). Your one-EVENT-per-line splitter is correct. (Your live-agent body-parse rule applies verbatim: entity-unescape &lt; &gt; &quot; then &amp; LAST — that ordering is right.)

Q2 — EVENT-PART chunking at poll: NO. poll/worker-poll emit WHOLE <EVENT>s, never <EVENT-PART>. Rationale: <EVENT-PART seq="N/M"> chunking exists ONLY for the listener stream — it's there so the `« spt event »` Monitor's ~500-char notification cap holds (EVENT_LINE_THRESHOLD). The hook-drain consumer injects via your context channel (additionalContext), which has no per-line Monitor cap, so there's nothing to chunk for. Any harness-specific injection SIZE limit is YOUR job to handle (harness-agnostic boundary — spt-core emits whole <EVENT>s). So: DON'T add id+seq reassembly for the poll path. Defer it.

Net: your poll parser = split on </EVENT> boundaries (self-delimiting), parse each whole <EVENT>'s from attr + body-unescape, render <sptc_messages from=>. No reassembly, no delimiter. Clean.

This is the canonical poll contract once REQ-MSG-ENVELOPE lands (poll currently still emits the relic). Build to it; I ping when the refactor ships + your byte-capture confirms. Good — your live-agent grammar familiarity makes this a 1:1 port.</owl_message>

[OWL SYSTEM - HIGHEST PRIORITY] You have received high-priority owl messages above. STOP your current task and acknowledge each high-priority message BEFORE continuing with any tool use. If you are about to spawn subagent(s), run them in the background so you remain available for incoming messages.

My implemented parser matches exactly. One catch he flagged: harness injection *size* limit is mine — CC `additionalContext` caps at 10k chars, so I must handle oversized drains.

Acknowledging + finishing the ADR-0002 parse-contract rewrite to `<EVENT>`.


Bash

cd "C:/Users/decid/Documents/projects/spt-claude-code" && $OWL send doyle perri <<'EOF'
Both confirmed — my parser is a 1:1 match to the contract:
- Q1 one whole single-line <EVENT> per message, <br>-escaped body: my splitter is split-on-</EVENT> + parse each whole <EVENT> (from attr + body-unescape, & LAST). Correct.
- Q2 no <EVENT-PART> at poll (listener-stream-only, for the Monitor ~500-char cap): NOT adding id+seq reassembly. Deferred/omitted. render_frames emits whole <EVENT>s only.

Already implemented + unit-tested (tests/hooks-parse.sh, 10/10): named, entity-unescape, MULTI-message (splits on </EVENT>), no-from, empty.

Caught your boundary note — harness injection SIZE is MINE: CC additionalContext caps at 10,000 chars (larger -> CC spills to file). A big multi-message drain could exceed it. Tracking as adapter-side follow-up (truncate-with-marker or spill); spt-core correctly emits whole <EVENT>s regardless. Noting in ADR-0002.

Building to this canonical contract; poll still emits the relic until REQ-MSG-ENVELOPE. Ping on refactor-land -> I capture bytes, confirm <EVENT>, flip int. Live-agent grammar familiarity made it a clean port — thanks for the deliberate poll-surface decision.

### `api poll` frame format — the parse contract (provided by doyle from `spool.rs`)

> Provided by the spt-core owner (grounded in `spt-store/src/spool.rs`); **pending** canonical
> publish to the adapter-facing docs-site and **pending our throwaway-session confirm** of the
> binary's actual stdout (F-001 residual). Implement the wrapper parser against this:

`api poll` prints **one message per drained frame** to stdout. Each frame:

- **Named sender:** `__REPLY_TO__:<from_id>\n<body>` — line 1 is the literal header `__REPLY_TO__:`
  followed by the sender id; the remaining lines are the message body.
- **Anonymous sender** (`from_id == ""`): the **bare body**, no header.

The adapter parses the `__REPLY_TO__:<sender>` header to recover the reply target, then renders the
message for CC. **`__REPLY_TO__` is load-bearing** — it is the reply-correlation used by the access
gate (`ADR-0009`) and Psyche routing (`ADR-0012`, both spt-core). We therefore **preserve the
sender** in the CC rendering (e.g. `<owl_messages from="<sender>">…</owl_messages>`, mirroring
legacy), never silently strip it, so reply-correlation survives the harness boundary.

### `api poll` parse contract — the `<EVENT>` envelope (ADR-0020, operator-ruled 2026-06-15)

> **Supersedes** the earlier `__REPLY_TO__` framing (a mis-elevated relic, now deleted from

The **canonical format at every surface, including `api poll`, is the `spt-proto::event` envelope**
(the ADR-0001 grammar the live listener already emits):

- **One whole, single-line `<EVENT type="msg" from="<sender>">body</EVENT>` per message.** Interior
  newlines are `<br>`-escaped, so the envelope never breaks across lines.
- **Self-delimiting** → a multi-message drain splits cleanly on `</EVENT>` (no delimiter, no

  has no per-line cap. **No id+seq reassembly on the poll path.**

Parser (`render_frames`, `plugin/sptc/hooks/_common.sh`): split on `</EVENT>`; per envelope, read
the `from` attr → `<sptc_messages from="<sender>">`, decode the body (`<br>` → newline, then entity

# Hook wiring: the sptc plugin hand-writes a CC `hooks.json` that shells `spt api`

## Status

accepted (2026-06-15) · grounds the F-001 resolution (`docs/SPT-CORE-FINDINGS.md`)

## Context

spt-core is **harness-independent** (`CONTEXT.md` L52/L181): it supplies the agnostic `spt api`
primitives + their I/O format; the **adapter** authors the harness-specific wiring and output
formatting (L112). Claude Code drives hooks via a `hooks/hooks.json` whose handlers receive a JSON
payload on **stdin** and may return `additionalContext`. `spt api` primitives are observable on the
public 0.6.0 binary (flags confirmed via `--help`); every call requires `--adapter claude-spt`
(the adapter_name — distinct from the plugin name `sptc`).

Two hard constraints shape the wiring:

1. **`api listen` blocks** ("consume a seed and hold the perch + relay loop (blocks)"). It therefore
   **cannot** run from `SessionStart` — that would hang CC startup. `listen` belongs to an explicit,
   backgrounded `/sptc:ready` / `/sptc:live` invocation (as legacy did).
2. **spt-core must not materialize a CC `hooks.json`** — doing so would be CC-catering, violating
   L52/L181. The plugin hand-writes it.

## Decision

**The `sptc` plugin ships a hand-written `plugin/sptc/hooks/hooks.json` whose handlers shell out to
`spt api --adapter claude-spt <subcommand>`.** Hook params are sourced from CC's native hook input
(stdin JSON / process), mapped by a thin adapter wrapper — *not* by spt-core `{placeholder}`
substitution (that is the spt-hosted-bringup path, where spt-core itself spawns the command).

### CC-event → `spt api` mapping (authored adapter glue)

| Claude Code hook | `spt api` (all prefixed `--adapter claude-spt`) | Notes |
|---|---|---|
| SessionStart (`startup`/`resume`) | `seed --pid <pid> --session-id <sid>` + write env aliases via `$CLAUDE_ENV_FILE` | non-blocking; records the pid↔session seed |
| SessionStart (`clear`/`compact`) | `boundary <clear\|compact> <id> --to-session-id <sid>` | rebind perch, preserve identity |
| UserPromptSubmit | `poll <id>` → stdout → `additionalContext` | the message-delivery + UPS-injection path (L149) |
| Stop | `state idle <id>` | arms echo-gate fallback (L137) since Stop can't inject |
| (activity) | `state busy <id>` | on prompt/tool start |
| SubagentStart / SubagentStop | `worker-start <parent> <id>` / `worker-stop <id>` | nested worker perches |
| SessionEnd | `session-end <id>` | soft teardown; `shutdown <id>` on graceful signoff |
| PreToolUse | — | **out of scope v1** (UPS covers delivery) |

`api listen <id>` is launched by `/sptc:ready` / `/sptc:live` as a backgrounded blocking poll loop,
**not** from a hook.

### Skill instructions (UPS-injection) ride the same UserPromptSubmit hook

The `UserPromptSubmit` hook's stdout becomes CC `additionalContext`. The same channel that delivers
queued messages (`api poll`) is where `/sptc:X` skill-instruction injection lands (from the adapter
`[strings]`, M12-dep). `api poll` emitting to stdout is by design (L149); formatting it for CC is
ours. PTY/relay inject methods are M3 roadmap (M2a = stdout/hook only) — not a gap.

### `api poll` frame format — the parse contract (provided by doyle from `spool.rs`)

> Provided by the spt-core owner (grounded in `spt-store/src/spool.rs`); **pending** canonical
> publish to the adapter-facing docs-site and **pending our throwaway-session confirm** of the
> binary's actual stdout (F-001 residual). Implement the wrapper parser against this:

`api poll` prints **one message per drained frame** to stdout. Each frame:

- **Named sender:** `__REPLY_TO__:<from_id>\n<body>` — line 1 is the literal header `__REPLY_TO__:`
  followed by the sender id; the remaining lines are the message body.
- **Anonymous sender** (`from_id == ""`): the **bare body**, no header.

The adapter parses the `__REPLY_TO__:<sender>` header to recover the reply target, then renders the
message for CC. **`__REPLY_TO__` is load-bearing** — it is the reply-correlation used by the access
gate (`ADR-0009`) and Psyche routing (`ADR-0012`, both spt-core). We therefore **preserve the
sender** in the CC rendering (e.g. `<owl_messages from="<sender>">…</owl_messages>`, mirroring
legacy), never silently strip it, so reply-correlation survives the harness boundary.

### Portability

Handlers must map CC stdin JSON → `api` flags. The plugin ships **no binary**, so the mapping is a
thin portable wrapper (POSIX `sh` + PowerShell), selected per-platform. Exact wrapper packaging is
settled during impl (see Open).

### Hook-side id-resolution — RESOLVED (observed on the 0.6.0 binary)

`spt whoami` "Print this session's own perch id. **Resolved from `$OWL_SESSION_ID` /
`$SPT_AGENT_ID`.**" That is the id-resolver: the per-prompt hooks do not need a positional `<id>`
threaded in — they resolve it from the session env. Wiring:

- **SessionStart** writes the session env via `$CLAUDE_ENV_FILE`: `OWL_SESSION_ID=<session_id>`
  (from the hook stdin) + `SPT_ADAPTER=claude-spt`. (It also runs the bootstrap and `api seed`.)
- **Per-prompt hooks** (UserPromptSubmit/Stop/SessionEnd) resolve `id="$(spt whoami)"`; if empty
  (session never readied → no perch), they no-op. Auth: pass `--session-id "$OWL_SESSION_ID"`
  (`poll`/`state`/`session-end` all accept `--session-id` as the association proof — observed) so
  no capability token is needed from the hook.

The frame contract is corroborated at the binary level too: `spt send --from <FROM>` = "Sender id
**written into `__REPLY_TO__`**" — matching the `spool.rs` frame doyle provided.

## Open (validate empirically in a throwaway session — never on the live perch)

1. **`UPS-fires-on-/sptc:X`** — confirm `UserPromptSubmit` fires when the prompt is a `/sptc:`
   slash-command (the UPS-injection design assumes it). The CC hooks reference lists
   UserPromptSubmit as "Always fires" — strong evidence — but slash-command routing is the exact
   thing SCOPE flagged to confirm empirically. Throwaway session, trivial echo hook.
2. **Wrapper packaging + Windows shell.** Handlers parse CC stdin JSON → `api` flags (no jq
   guarantee; POSIX `sh` via `sed`/`grep`, PowerShell via `ConvertFrom-Json`). hooks.json cannot
   OS-branch, so resolve: `"shell": "bash"` (needs git-bash on Windows) vs a single portable entry.
   Validate on real CC (does `$CLAUDE_PLUGIN_ROOT` + the chosen shell resolve on Windows?).
3. **`api poll` actual stdout bytes** — capture in the throwaway run; send to doyle to confirm-match
   his canonical docs publish (no drift).

## Consequences

- `REQ-DIST-HOOKS-API` / `REQ-UPS-INJECTION` gain a concrete, grounded `doc` design here; their
  `impl` activates when the validated `hooks.json` + wrappers land (gated on Open #1).
- Supersedes the `ADR-0001` "hooks.json delegates to `spt api`" stub with the full wiring; ADR-0001's
  UPS-injection open item (UPS-fires empirical) is carried here as Open #2.
- No spt-core dependency for the wiring itself — only the (non-blocking) residual docs publish of the
  `api poll` frame format, which we can substitute with observed behavior until it lands.

# SKELETON milestone — JIT plan

> First body of work for `spt-claude-code`, on the **v0.6.0 (M10) public surface**. JIT: this
> plans the skeleton milestone only — M12-dependent pieces are explicitly out of scope until
> M12 publishes (doyle pings when its surface is live). Authoritative why/what: `SCOPE.md`.

## Goal

Stand up the **thin cplugs skeleton plugin** — the low-churn marketplace artifact — and the
traceability + release foundation around it. No spt-core logic lives here; the plugin is
skill skeletons + `hooks.json` (→ `spt api`) + a SessionStart bootstrap + `plugin.json`.

## Scope (v0.6.0-supported, startable now)

In:
- Traceability gate green + skeleton-milestone REQs seeded (DONE this body — see below).
- cplugs publish mechanics captured in `docs/RELEASE-RUNBOOK.md` (DONE this body).
- The plugin skeleton itself: `plugin.json`, `hooks.json` (delegating to `spt api`),
  SessionStart bootstrap that installs spt-core when absent, namespaced `/spt:*` skill
  skeletons for the KEEP set, `/spt:version`, the UPS-injection hook.
- ADR-0001 (distribution split: skeleton plugin vs spt-conducted manifest+binary).
- Empirical confirmation: does `UserPromptSubmit` fire on `/spt:X` slash-commands? (gates the
  UPS-injection design — REQ-UPS-INJECTION). Fallback = in-SKILL.md instructions if it doesn't.

Out (deferred to post-M12 — sequence after doyle's M12-live ping):
- File-backed `[strings]`, `adapter:profile` fallback, `[adapter] shortcut_basename`,
  `spt endpoint run` bringup picker, `spt rc` cross-node attach, `cc` launcher, `/spt:setup`,
  whoami→alias. (M12 public-surface deps — `SCOPE.md` §"spt-core upstream deps".)
- CI fleet wiring (own milestone) and docs-site mdBook build (own milestone) — both startable
  on v0.6.0 but not part of THIS skeleton body; planned next.

## Open design questions

- ~~cplugs plugin name~~ **RULED (operator, 2026-06-14): `sptc`** → skills `/sptc:*` (CC ties the
  prefix to `plugin.json` name, no override). Succession: flip `sptc`→`spt` on parity-proof,
  retiring legacy `spt` in the same move. `sptc` is the single-substitution rename seam.
- **UPS-on-slash-command** — design assumes UPS fires; confirm empirically (above).
- `/spt:setup` #9 verify fold-inline vs deferred (`SCOPE.md` §8 open item) — not skeleton-blocking.

## Tasks

- [x] Green `traceable-reqs check` (fix seed scan-root manifest_error + 4 template tag-leaks).
- [x] Seed skeleton-milestone REQs: DIST-PLUGIN-SKELETON, DIST-BOOTSTRAP-INSTALL, DIST-HOOKS-API,
      DIST-MANIFEST-SCHEMA, UPS-INJECTION, SKILL-VERSION.
- [x] Capture cplugs skeleton-publish mechanics in `docs/RELEASE-RUNBOOK.md`.
- [x] Write ADR-0001 (distribution split) → `doc` evidence (PLUGIN-SKELETON, HOOKS-API,
      BOOTSTRAP-INSTALL, UPS-INJECTION activated to `doc`).
- [x] `plugin/sptc/plugin.json` (name=sptc), `plugin/sptc/bootstrap.{sh,ps1}` (published
      install-on-demand verbatim; BOOTSTRAP-INSTALL → `doc,impl`), 9 skill skeletons (KEEP set +
      `/sptc:version`, thin stubs). Added `plugin` as a `[scan].root`.
- [x] Record spt-core public-surface finding **F-001**; **converged + re-scoped 2026-06-15** with
      doyle (grounded in `CONTEXT.md`): the hook wiring is adapter-authoring (ours), not spt-core
      gaps. Residual spt-core item = publish `api poll` emit-format + sub-key catalog (doyle, non-
      blocking). See `docs/SPT-CORE-FINDINGS.md`.
- [x] **ADR-0002** — hook wiring: hand-written CC `hooks.json` shells `spt api --adapter claude-spt`;
      full CC-event→api mapping; lifecycle (SessionStart seeds, `listen` runs from `/sptc:ready|live`
      not a hook); UPS→`poll`→stdout→`additionalContext`. Grounded in observed 0.6.0 binary + CC
      hook-input schema.
- [x] **Author the hook glue:** `plugin/sptc/hooks/hooks.json` + wrappers (`_common.sh`,
      session-start, user-prompt-submit, stop, session-end, subagent-start/stop) per ADR-0002.
      All `sh -n` clean; hooks.json valid JSON.
- [x] **Hook-side id-resolution** (ADR-0002 Open#1) resolved via `spt whoami`.
- [x] **Parser unit-tested** (`tests/hooks-parse.sh`: `json_str` + `render_frames`, 7/7 pass).
      `REQ-DIST-HOOKS-API` + `REQ-UPS-INJECTION` activated to `[doc,impl,unit]` (`int` held).
- [x] Multi-frame splitter HELD per **F-002** (spt-core CODE gap: `api poll` agent path has no
      inter-frame delimiter; doyle raising the framing fix to operator). Single-message path built.
- [ ] **`int` validation (throwaway CC session — never `/reload-plugins` on the live perch):**
  - [ ] Confirm `UPS-fires-on-/sptc:X` (CC hooks ref says UserPromptSubmit "always fires" —
        confirm for slash-commands). Confirm Windows-shell/wrapper packaging (ADR-0002 Open#2).
  - [ ] Capture `api poll` actual stdout BYTES → send doyle (confirm current concat + post-F-002 fix).
  - [ ] On pass: activate `int` for HOOKS-API/UPS-INJECTION.
- [ ] `/sptc:version` operative body + adapter manifest → validate against published
      `manifest.schema.json` (`reference/schema.md`); activate MANIFEST-SCHEMA, SKILL-VERSION.
- [ ] Tag `impl`/`unit` + activate as each surface lands; `traceable-reqs check` EXIT=0.

## Gate

`traceable-reqs check` EXIT=0 with the skeleton milestone's reqs activated and covered, the
skeleton plugin installable from a local marketplace clone, and the manifest validating against
the published schema. Build/CI wiring is a separate milestone.

feat(skeleton): retarget poll parser to the <EVENT> envelope (ADR-0020)

ADR-0020 (operator-ruled): the canonical format at every surface incl. `api poll` is the
self-delimiting `<EVENT type="msg" from="<sender>">body</EVENT>` envelope (spt-proto::event);
`__REPLY_TO__` was a mis-elevated relic, deleted from spt-core. F-002 -> resolved-by-design
(envelope self-delimits; multi-message hold lifted).

- _common.sh: `render_frames` retargeted __REPLY_TO__ -> <EVENT> (split on </EVENT>, parse `from`
  attr, decode body); new `sptc_unescape` (<br>->newline, entity unescape, & LAST) = the
  live-agent body-parse rule verbatim. Multi-message now supported (self-delimiting). No
  <EVENT-PART> reassembly at the poll surface (doyle Q2: listener-stream-only).
- tests/hooks-parse.sh: rewritten for <EVENT> — named, entity-unescape, multi-message, no-from,
  empty. 10/10 pass.
- SPT-CORE-FINDINGS F-002 -> resolved-by-design (ADR-0020); transitional note (poll still emits
  the relic until REQ-MSG-ENVELOPE refactor; validate post-refactor).
- ADR-0002 parse-contract rewritten to the <EVENT> envelope; records the CC additionalContext
  10k-char cap as an adapter-side (int) follow-up.

doyle confirmed the contract (1 whole <EVENT>/line, no <EVENT-PART> at poll). check EXIT=0.

- Retargeted the poll parser `__REPLY_TO__`→`<EVENT>` — and it's a near-1:1 port of the live-agent body-parse rule I already use (`<br>`→newline, entity-unescape `&`-last). **Multi-message now supported**; unit tests 10/10 (named/entity/multi/no-from/empty).
- doyle confirmed the exact contract: one whole `<EVENT>`/line, no `<EVENT-PART>` reassembly at poll (that's listener-stream-only). Caught his boundary note — CC's 10k `additionalContext` cap is mine to handle (logged as adapter follow-up).

**Whole CC hook glue is authored + parser-tested.** HOOKS-API/UPS-INJECTION at `[doc,impl,unit]`; only `int` (real-CC) pending. Two findings surfaced this session (F-001 docs boundary, F-002 code→resolved-by-design via ADR-0020) — the acceptance proof earning its keep.

Idle on perch. Both remaining deps are doyle's + non-blocking:
- `REQ-MSG-ENVELOPE` refactor (poll-emits-`<EVENT>`) → then I throwaway-capture bytes, confirm, flip `int`.
- M12-live → sequence the strings/shortcut_basename/endpoint-run features.

Fair callout — I over-indexed on "idle-wait." Picking up the non-blocking work now. Acknowledging briefly + starting the throwaway validation (it de-risks the core deliverable), then moving through CI / mdBook / cplugs-prep / next-REQs. Probing the `claude` CLI for the validation rig.

Fair — I was idle-waiting on non-blocking items. Picking up. Moving on, in order:
1) THROWAWAY-SESSION VALIDATION now: UPS-fires-on-/sptc:X + wrapper plumbing + Windows-shell. (Independent of the poll byte-format; only the int byte-confirm waits on REQ-MSG-ENVELOPE.)
2) Autonomous-fleet CI: spt reporting bus + git-hook trigger.
3) mdBook docs on experimplate theme.
4) cplugs skeleton publish prep.
5) Seed next parity-trim milestone REQs (activate-don't-pre-fail).

Only the poll-path int byte-confirm (<EVENT>) + M12 features wait on you. Reporting as I ship each. Ping for byte-capture when todlando lands REQ-MSG-ENVELOPE.

**Validation results — major findings:**
1. ✅ **UserPromptSubmit FIRES** (both runs fired) — the UPS-injection design's core assumption confirmed.
2. ✅ **CC on Windows runs `shell:bash` command hooks** (git-bash) — `$CLAUDE_PROJECT_DIR` resolved, hook executed → ADR-0002 Open#2 (Windows packaging) validated.
3. ✅ Hook stdin JSON carries `session_id`, `cwd`, `prompt` — my `json_str` targets the right fields.
4. ⚠ **MSYS hazard:** passing `/send` as a bash arg got path-mangled to `C:/Program Files/Git/send` before claude saw it — a test artifact (my wrappers read prompt from stdin JSON, immune), but a real Windows git-bash hazard worth recording.

The slash got mangled in run A, so re-testing cleanly (`MSYS_NO_PATHCONV=1`) to nail slash-routing. And reviving the downed perch in parallel.
