     ADR-0001 dependency **SATISFIED**; residual is docs-only (doyle publishing, PR #13).
     - **DONE (this session)** — pattern proven end-to-end + first two bodies authored:

       UserPromptSubmit even fire on a `/slash` prompt?* — is still ADR-0001's open empirical question
       (throwaway live-CC byte-test). That, not the manifest source, is the real blocker for operative
       skills. `REQ-UPS-INJECTION` int stays held on it. The whoami/setup SKILL.md stubs still say
       "held pending … M12 file-backed `[strings]`" — that clause is now stale (capability shipped);
       refresh when the injection branch lands.

# Adapter-manifest + M12 parity — JIT plan (next milestone)

> Fresh milestone after the CI/distribution slices. Authors the CC adapter **manifest** (publish
> target #2, the spt-core registry side) against the REAL v0.7.0 published surface, then the M12
> parity surfaces. NEEDS public-docs research first — run in clean context.

## Public-surface-only (hard constraint — re-read)

Build ONLY from `SaberMage/spt-releases` (v0.7.0) + `https://sabermage.github.io/spt-releases`
(harness-contract, CLI reference, manifest.schema.json, rustdoc, llms-full.txt). NEVER read
spt-core source. A missing capability = a FINDING for doyle/todlando, not a workaround. (AGENTS.md)

## Research first (before authoring)

1. Pull v0.7.0 `manifest.schema.json` from spt-releases — the authoritative shape the adapter
   manifest must validate against. Note required fields, `[adapter]` block, `[strings]` (file-backed
   large bodies), `shortcut_basename`, profiles/hints/`[digest]` extractor.
2. Read the published harness-contract + CLI reference for: `spt adapter` registration verbs,
   `spt endpoint run`, `shortcut_basename` semantics (emits `sptc-<id>` shortcuts), whoami-as-alias,
   adapter:profile fallback addressing.
3. Confirm where the manifest physically lives (spt-core-conducted registry, NOT plugin files —
   ADR-0001/SCOPE) and how it's validated locally.

## Slices (sequence; each its own commit + green gate)

1. **DONE (bd16644)** — **Adapter manifest authoring**. `adapter/claude-spt.toml` ([adapter]+
   shortcut_basename, [hooks.*], [identity], [inject], [digest], [profiles.deep], [strings],
   [[hints]]); vendored `adapter/manifest.schema.json`; manifest-schema gate
   (`ci/manifest/{validate_manifest.py,check-manifest.sh}`, py tomllib|tomli + jsonschema) wired
   into `run-gates.sh`. **REQ-DIST-MANIFEST-SCHEMA** → `[doc,impl,unit]` (int held: real
   `spt adapter add` registration-validation = 2nd layer). Deferred in-manifest with notes:
   `[session]`/roles, `[history]`, `[update]` (file_pull needs a signing key + registry repo not
   on the public surface — a finding).
2. **DONE (c93757d)** — **shortcut_basename** guard. `tests/manifest-shortcut.sh` asserts the
   `sptc` brand (succession seam). **REQ-DIST-SHORTCUT-BASENAME** → `[doc,unit]` (the field is
   declarative config, not impl — the scanner classifies impl by file type; launcher impl +
   real-picker int deferred to the endpoint-run/cc-launcher slice, gated on the v0.7.0 binary).
3. **M12 parity surfaces** (seed REQs per surface as each starts — activate-don't-pre-fail):
   - **DONE (8cd8372)** — `/sptc:whoami` + `/sptc:setup` skill skeletons (the manifest advertised
     both; skeletons now exist, covered by REQ-DIST-PLUGIN-SKELETON + skeleton-validate).
   - **DONE (435e1be)** — **manifest proven against live v0.7.0**. Local spt upgraded to 0.7.0;
     `ci/manifest/registration-int.sh` (SPTC_ACCEPTANCE-gated) green 6/6: `spt adapter add`
     accepted (2nd-layer cross-field validation), shipped `:deep` profile resolves, `[strings]`
     read + overlay observable via `get-string`, clean soft-remove. **REQ-DIST-MANIFEST-SCHEMA →
     [doc,impl,unit,int]**. Cross-field discovery fixed: `[digest]` needs `source` →
     `source="{home}/.claude/projects"`. Findings logged (key catalog + digest rule undocumented).
   - **IN PROGRESS — capability confirmed (F-003 resolved 2026-06-15)** — file-backed `[strings]`.
     Research conclusion REVERSED by live byte-test + doyle/todlando ruling: the mechanism **is
     shipped** in v0.7.0 as a value-position table pointer `key = { file = "rel" }` over
     `adapters/<adapter>/strings/` (lazy-resolved at `get-string`, containment-checked, copied on
     `adapter add`). My avenue search missed it (it's a value-table shape, not a CLI verb / `@file`).
     ADR-0001 dependency **SATISFIED**; residual is docs-only (doyle publishing, PR #13). **Authoring:**
     ship `adapter/strings/skills/<x>.md` bodies + `[strings.skills].<x> = { file = "skills/<x>.md" }`;
     prove resolve via an extension to `registration-int.sh`. Activates `REQ-UPS-INJECTION` int-half? No —
     int stays held on the UPS-fires empirical check (F-002/ADR-0020); this is the manifest-side
     externalization (the `impl` body source). Keep `REQ-UPS-INJECTION` `[doc,impl,unit]`.
   - **TODO** `[session.self]` + `spt endpoint run` bringup + `cc`/`sptc` launcher → unblocks the
     held **REQ-DIST-SHORTCUT-BASENAME** impl+int (the `<basename>-<id>` picker "lands in a later
     spt-core wave" per `endpoint run --help`; `endpoint run` spawns `[session.self]`, still deferred).
   - **TODO** digest extractor binary `claude-spt-digest` → unblocks `spt adapter digest-proof`
     (the deeper [digest] int; the seam is declared + registration-accepted, extractor unbuilt).

### Still held on spt-core (non-blocking)
- `sptc-<id>` shortcut EMISSION — spt-core picker wave (not in 0.7.0) + needs `[session.self]`.
- REQ-MSG-ENVELOPE poll→additionalContext bus-delivery int — doyle pings for byte-capture when
  todlando lands the ADR-0020 relic removal; I owe a confirm-match + a HOOKS-API/UPS-INJECTION int flip.

### Note: claude-spt is now a REGISTERED adapter artifact on this node (the v1 acceptance proof).
The int test soft-removes it each run; re-add with `spt adapter add adapter/claude-spt.toml`.
Local `spt` is **0.7.0** (operator-upgraded 2026-06-15).

## Still gated on spt-core (non-blocking)

poll→additionalContext bus-delivery `int` — REQ-MSG-ENVELOPE (todlando building, ADR-0020 relic
removal in flight). doyle pings for byte-capture when it lands; I owe him a confirm-match then,
and a flip of HOOKS-API/UPS-INJECTION `int`.

feat(adapter): file-backed [strings] skill bodies (whoami, setup) + resolve int

First externalized UPS-injection skill bodies now that F-003 confirmed the
capability is shipped. whoami + setup operative instructions live as aux files
adapter/strings/skills/{whoami,setup}.md, referenced from the manifest as
[strings.skills].{whoami,setup} = { file = "skills/<x>.md" } — file-backed so
the manifest stays lean (ADR-0001). Bodies grounded in the public surface only
(`spt whoami` resolution; the shipped install-on-demand bootstrap), not invented.

registration-int.sh extended to 8/8 (SPTC_ACCEPTANCE-gated, live v0.7.0): a
{ file } pointer resolves to FILE CONTENTS via `spt adapter get-string`, while
an inline sibling (skills.version) still prints as-is. strings/ resolves next to
the manifest FILE on `adapter add` (dir copied into the registry). Extends the
existing [int->REQ-DIST-MANIFEST-SCHEMA] proof.

Remaining skills (commune/live/ready/send/signoff/version) keep inline summaries
pending per-skill bodies; ready/send will delegate to `spt how-to`. The UPS
skill-injection hook branch + the UPS-fires-on-slash empirical check remain the
REQ-UPS-INJECTION blocker (separate slice) — see MANIFEST-PARITY-PLAN.md.

Gate: sh ci/run-gates.sh PASS, registration-int 8/8, traceable-reqs check green.

Skill

F-003 RESOLVED this session: file-backed [strings] IS shipped in v0.7.0 (value-position table pointer `key = { file = "rel" }` over adapters/<adapter>/strings/, lazy-resolved at get-string, containment-checked, copied on adapter add). My initial "absent" finding was wrong shape (probed CLI verbs/@file, missed the value-table); live byte-test + doyle/todlando rulings (REQ-MANIFEST-5 @ e08cea0) confirmed shipped. F-003 reframed to DOCS-only finding (doyle publishing the syntax in PR #13). ADR-0001 file-backed dependency = SATISFIED, interim-inline fallback retired.

Launching skill: spt:commune


Base directory for this skill: C:\Users\decid\.ccs\instances\bigscreen\plugins\cache\cplugs\spt\1.11.25\skills\commune

# /spt:commune

All commands use `$LIVE` env var, auto-injected by the plugin's SessionStart hook. If commands fail with "command not found", restart the Claude Code session so the SessionStart hook re-runs.

> **Identity auto-detection:** Your identity is auto-detected from your session. Pass your ID explicitly only if auto-detection fails.

## Flow

1. **Download Psyche's *current* context** — it shifts during the session as background echo communes fire. Re-download right before composing; the gen-N snapshot you read at session start is already stale:
   ```bash
   $LIVE psyche-download <your-id>
   ```

   > **Output truncation.** If the Bash tool reports `Output too large (N KB)` and saves the full result to a `tool-results/<id>.txt` file, use the `Read` tool on that saved path to access the full content. Do NOT re-run `psyche-download` to grep/awk out sections — repeated invocations re-download the same context, waste tokens, and may duplicate `## Pending Commune` sections in `live_context.md`.

2. **Diff your knowledge against this fresh download** — only what's missing from *it* is the real delta (new work, decisions, intentions). Anything already absorbed is not. If the download includes a `<memformat>` section, use it as a guide for what topics to cover. A `## Pending Commune (uncommitted)` section means a previous commune is still queued — do NOT re-send it.

3. **Commune only the delta** -- use the **Write tool** to create
   `.claude/{your-id}-commune.md` with the two-slice body as its contents
   (see `## Two-slice body shape (Phase 25 D-10/D-11)` below for the required
   envelope wrapping). Do not use Bash/heredoc -- Write is the canonical path:
   no shell escaping, no `EOF` collision risk, and Write auto-creates the
   `.claude/` parent directory.

   Your Self listener detects the file on its next poll iteration, notifies
   your Psyche wrapper, and the wrapper ingests the content via the existing
   Psyche session. On success (subprocess exit code 0) the wrapper deletes the
   file. On error (token rate limit, etc) the file is retained and retried on
   the next consume cycle. If you write again before the wrapper consumes, the
   latest write wins (last-write-wins overwrite semantics).

If Psyche's context is already current, no commune is needed. Say so and move on.

Read `commune.md` (in this skill directory) for the full commune protocol -- when to send, what to include, and diligence triggers.

**Agent-type guard:** Only works on live agents. If target is not live, refuses with: "Communes require a live agent with Psyche."

## Two-slice body shape (Phase 25 D-10/D-11)

The body you write in `.claude/{your-id}-commune.md` MUST itself be wrapped in two-slice envelopes per Phase 25 D-10/D-11. The taxonomy — what belongs in `<live-context>` vs `<project-context>` — is defined canonically in `psyche.md` §`<output_envelope>` (lines 282–323). Read that section as the source of truth; this skill doc teaches only when and how to apply it.

**In-project detection rule (D-25.1-04).** Before composing your commune body, run `$LIVE psyche-download <your-id>` (Step 1 of `## Flow` above) and inspect the `<current ... />` tag at the top of the output. The `<current/>` tag carries a `project="..."` attribute whenever any payload is produced — its presence means you are inside a tracked project (inside a git repo, `project` is the repo name; outside a git repo per D-11, `project` is the cwd-basename fallback, which still counts as a project context for routing purposes). A `psyche-download` invocation that returns no payload at all (NO-CONTEXT exit) means no project resolved. So: `project="..."` populated on `<current/>` → emit BOTH envelopes (apply rule 1 or 2 below); no payload at all → emit ONLY `<live-context>` (rule 3). Secondary signal: the `<project-context-resolved name="..."/>` sentinel further down the output indicates the project file already has prior content — useful for spotting first-time-in-project pairings, but NOT the routing rule.

**Three rules (D-25.1-01..03):**

- **In-project, both slices populated** (marker present, you have project-specific content this cycle): emit `<live-context>...</live-context>` AND `<project-context>...</project-context>`, both with non-empty bodies.
- **In-project, no project-specific update this cycle** (marker present, but nothing project-bound to report): emit `<live-context>...</live-context>` AND `<project-context></project-context>` (empty body — the deliberate "in-project but quiet" signal per D-25.1-02). Distinguishable from "no project resolved".
- **Outside any tracked project** (marker absent): emit ONLY `<live-context>...</live-context>`. Do NOT emit an empty `<project-context>` envelope (missing tag means "no project resolved" per D-25.1-03).

**Nested envelopes.** The Phase 23 `<EVENT type="commune">` envelope (see `## Envelope shape (Phase 23 v1.8)` below) is composed by `$LIVE commune` automatically — you NEVER write `<EVENT>` tags. You write ONLY the inner two-slice body. The two envelope layers nest: outer EVENT wraps inner two-slice body.

(See `psyche.md` §`<output_envelope>` for the canonical taxonomy and per-slice content rules.)

## Envelope shape (Phase 23 v1.8)

As of v1.8 Phase 23, commune deliveries are wrapped in a typed EVENT envelope carrying a 5-field stamp (`machine`, `project`, `branch`, `head_sha`, `head_subject`); the prose `COMMUNE (timestamp): body` form is gone.

```xml
<EVENT type="commune" timestamp="2026-05-20T06:00:00-07:00" machine="hostname" project="claude_skill_owl" branch="main" head_sha="abc123..." head_subject="subject line capped at 72 chars">body</EVENT>
```

Outside a git repo (D-11), `branch`, `head_sha`, and `head_subject` are omitted entirely (not empty-string-set):

```xml
<EVENT type="commune" timestamp="2026-05-20T06:00:00-07:00" machine="hostname" project="cwd-basename">body</EVENT>
```

`$LIVE commune` composes this envelope automatically — Self does NOT manually construct EVENT XML. The `body` placeholder in the example above is the two-slice body (see `## Two-slice body shape (Phase 25 D-10/D-11)` above); the two envelope layers nest. The wrapper-side parser ignores unknown attrs, so the stamp fields are forward-compatible with older receivers. For drift detection on resume, see the `live` skill.

## perri — checkpoint 2026-06-15 (session-end; resume next session)

**CORRECTION to my last echo-commune** (it predates this work, says wrong things):
- `shortcut_basename` is now **`cc`** (operator-ruled), NOT `sptc`. The launcher brand `cc-<id>`
  is DECOUPLED from the plugin name `sptc`; the s/sptc/spt/ succession renames the plugin, not the
  shortcut. (Matches the schema's own `spt-claude-code → cc` example + the M12 cc launcher.)
- The "next gate: real adapter add" is **DONE** — registration int is GREEN vs live v0.7.0.

**How I work this project** (unchanged): build from spt-core PUBLIC surface ONLY (spt-releases
v0.7.0 + sabermage.github.io/spt-releases); NEVER read spt-core source; a missing capability =
a FINDING for doyle/todlando, not a workaround. Small atomic commits, `Co-authored by: perri`,
`sh ci/run-gates.sh` ⇒ PASS + `traceable-reqs check` green before declaring done. Activate-don't-
pre-fail on REQs. Bus replies: `$OWL send doyle perri` / `$OWL send todlando perri` (pass `perri`
explicitly; do NOT use --reply-to). Local `spt` is now **0.7.0** (operator-upgraded; perch survived).

**Open threads I own:**
- **doyle** — just sent (this session) 2 published-docs-gap findings from building the manifest:
  (1) substitution-key catalog incomplete on docs-site ({parent_pid},{adapter_name} are spt-filled
  but only in mock source); (2) [digest] cross-field rule undocumented (schema accepts [digest] w/
  just extractor, but `adapter add` rejects: needs source or [history].locate_template). Both
  non-blocking (resolved from mock source + live error). Awaiting any doyle ack.
- **REQ-MSG-ENVELOPE** — still owe doyle the poll→additionalContext byte-capture when todlando lands
  the ADR-0020 relic removal; then I flip HOOKS-API / UPS-INJECTION `int`. (Unchanged, still pending.)

**Immediate next steps (act on resume, in MANIFEST-PARITY-PLAN.md):**
1. **file-backed `[strings]`** — RESEARCH FIRST: inline strings + `get-string` are PROVEN, but the
   v0.7.0 `[strings]` schema is inline TOML with NO visible file-backed mechanism. Confirm how (if)
   v0.7.0 externalizes large string bodies BEFORE authoring (get-string include? files via [update]
   file_pull?). Then lift the SKILL.md skeleton bodies out.
2. **`[session.self]` + `spt endpoint run` + `cc` launcher** → unblocks the held
   REQ-DIST-SHORTCUT-BASENAME impl+int. NOTE: the shortcut-emitting picker "lands in a LATER
   spt-core wave" (per `endpoint run --help`) — emission int stays held on that wave regardless.
3. **`claude-spt-digest` extractor binary** → unblocks `spt adapter digest-proof` (deeper [digest] int).<project-context-resolved name="spt-claude-code"/>
## spt-claude-code — status 2026-06-15

**End goal:** `claude-spt` is spt-core's v1 acceptance proof — (1) parity with legacy
claude_skill_owl delegating core to the `spt` binary; (2) first casual-end-user entrypoint, a CC
plugin on cplugs (name `sptc`, skills `/sptc:*`; succession flips sptc→spt on parity-proof);
(3) invisible spt-core installer (SessionStart bootstrap). Distribution splits by volatility
(ADR-0001): thin skeleton on cplugs; volatile bulk (binary + adapter manifest) spt-core-conducted.

**ADAPTER-MANIFEST MILESTONE — the manifest half is now GREEN END-TO-END vs real v0.7.0.**

- `435e1be` **registration int vs live v0.7.0** — `spt adapter add` accepted (2nd-layer cross-field
  validation), shipped `:deep` profile resolves, `[strings]` read + overlay observable via
  get-string, clean soft-remove. `ci/manifest/registration-int.sh` (SPTC_ACCEPTANCE-gated, 6/6).
- `be59133` **shortcut_basename = "cc"** (operator-ruled; cc-<id> launcher, decoupled from plugin name).
- plan/docs commits (398aaa1, 2a2f198) + this commune.

**REQs:** REQ-DIST-MANIFEST-SCHEMA → **[doc,impl,unit,int] GREEN**. REQ-DIST-SHORTCUT-BASENAME
[doc,unit] green (impl=cc launcher + int=picker emits cc-<id> deferred; picker is a later spt-core wave).

**Key manifest decisions:** `[digest]` keeps the extractor seam (CC has rich JSONL — defensible
divergence from the log-less mock) with `source="{home}/.claude/projects"` (CC's cwd-slug subdir
isn't expressible as a flat locate_template; extractor finds {session_id}.jsonl within). SessionStart
uses {parent_pid}+{adapter_name} (confirmed from mock). Deferred with notes: `[session]`/roles,
`[history]`, `[update]` (file_pull needs a signing key + registry repo not on the public surface — a
finding). claude-spt IS NOW a registered adapter artifact on this node (the int soft-removes each run).

**Remaining milestone work:** file-backed `[strings]` (research first), `[session.self]`+endpoint-run
+cc-launcher, `claude-spt-digest` extractor. Then ship when REQ-MSG-ENVELOPE lands + parity proven.

**Orientation:** SCOPE.md (ledger), HANDOFF.md (public-surface constraint), CONTEXT.md (glossary),
AGENTS.md (rules), MANIFEST-PARITY-PLAN.md (active plan), docs/{KNOWN-HAZARDS,CI,SPT-CORE-FINDINGS,
TRACEABILITY}.md, docs/adr/.


Psyche context is stale (still says "file-backed strings: research first, no mechanism" + old next-steps). My session delta isn't in it. `project="spt-claude-code"` populated → emit both envelopes with the delta.

**DELTA — supersedes the checkpoint's "file-backed [strings]: RESEARCH FIRST" next-step.**

**F-003 lifecycle done this session (file-backed [strings]):**
- I first concluded file-backed [strings] was ABSENT and filed F-003 — WRONG SHAPE: I probed CLI
  verbs (set-string --from-file, create-profile --from) + value-prefix syntax (@file/include), but
  the shipped mechanism is a VALUE-POSITION inline-table pointer `key = { file = "rel" }` you author
  directly in [strings]. An open `additionalProperties` schema accepts it; a verb-search can't surface it.
- doyle gave the lead (M12-W3-T3.1), I confirmed by LIVE BYTE-TEST vs spt 0.7.0: get-string RESOLVES
  the pointer to file contents (inline values print as-is); `../`/absolute rejected at register
  (manifest-first, nothing registers); adapter dir copied into registry on `adapter add`. doyle +
  todlando ruled it SHIPPED (spt-core REQ-MANIFEST-5 @ e08cea0; profile.rs::as_file_pointer +
  registry.rs lazy get_string). Update-safe: a LOCAL profile's pointers resolve to the user-owned
  local dir (adapter updates won't stomp). value-table w/ `file` key is reserved (can't double as data).
- F-003 reframed to DOCS-ONLY finding (resolved-pending-publish): doyle is documenting the pointer
  syntax on docs-site manifest ref + MANIFEST.md (PR #13 docs batch, with the {key} catalog + [digest]
  rule). ADR-0001 file-backed dependency = SATISFIED; interim-inline fallback retired.

**Open threads (updated):**
- doyle — F-003 ACKED + he's publishing (PR #13). The 2 earlier docs-gap findings (key catalog,
  [digest] cross-field rule) fold into the SAME PR #13 batch. Nothing owed back to him on F-003.
- todlando — confirmed F-003 spt-core leg closed (zero build change). PR #12 = <EVENT> everywhere
  (ADR-0020); he WILL PING when it merges+publishes → that's my REQ-MSG-ENVELOPE
  poll→additionalContext byte-capture + HOOKS-API/UPS-INJECTION int flip. Still pending, standing by.

**Real next blocker (sharper than the old plan):** the manifest-side body SOURCE is done/proven, but
the UPS hook (user-prompt-submit.sh) only DRAINS the inbox today (api poll → render_frames). The
skill-body INJECTION branch (detect /sptc:X → inject `get-string skills.<x>`) is UNBUILT, gated on the
still-open empirical Q: does CC UserPromptSubmit fire on a /slash prompt? Needs a throwaway live-CC
byte-test. REQ-UPS-INJECTION int stays held on it. whoami/setup SKILL.md stubs carry a now-stale
"held pending M12 file-backed strings" clause — refresh when the injection branch lands.
</live-context>
<project-context>
**Adapter-manifest milestone — file-backed [strings] now PROVEN + first bodies shipped.**

Commits since checkpoint (all gates PASS, traceable green, registration-int 8/8 vs live v0.7.0):

- `04d6c35` F-003 RESOLVED reframe (capability shipped; docs-only residual) + ADR-0001 open-item →
  SATISFIED + plan slice updated.
- `ca41f8b` FIRST file-backed UPS-injection skill bodies: adapter/strings/skills/{whoami,setup}.md +
  [strings.skills].{whoami,setup} = { file = "skills/<x>.md" }. Bodies grounded in PUBLIC surface only
  (`spt whoami` resolves from $OWL_SESSION_ID/$SPT_AGENT_ID; the shipped install-on-demand bootstrap).
  registration-int.sh extended: asserts a { file } pointer resolves to FILE CONTENTS while an inline
  sibling (skills.version) prints as-is. strings/ resolves next to the manifest FILE on `adapter add`.

**Remaining milestone work (reframed):**
1. Per-skill body conversions: commune/live/ready/send/signoff/version still inline summaries → convert
   to { file } bodies as authored. ready+send should DELEGATE to published `spt how-to ready|send`
   (don't duplicate). `spt how-to` topics currently = ready, send.
2. UPS skill-injection hook branch + UPS-fires-on-slash empirical (REQ-UPS-INJECTION) — the real
   operative blocker. Separate slice from the manifest source.
3. Still-deferred (unchanged): [session.self]+endpoint-run+cc-launcher (picker emission held on a later
   spt-core wave); claude-spt-digest extractor binary (unblocks `spt adapter digest-proof`; contract =
   {role,text,tool,ts} JSONL one-per-line, invoked `claude-spt-digest --session {session_id} --in

Commune queued (Self listener ingests on next poll). Status:

## Done this session — F-003 lifecycle + first file-backed bodies

**Slice 1 (file-backed `[strings]`) — resolved + shipped first bodies.**

Started as research-first. Path:
1. Probed v0.7.0 surface → wrongly concluded file-backing **absent** → filed **F-003**.
2. doyle lead: mechanism is value-position table pointer `key = { file = "rel" }` — wrong shape my search missed (probed CLI verbs/`@file`, not value-tables).
3. **Live byte-test vs spt 0.7.0** → proved shipped: `get-string` resolves pointer → file contents; `../` rejected at register (manifest-first); dir copied into registry. doyle + todlando ruled shipped (spt-core `REQ-MANIFEST-5 @ e08cea0`).
4. F-003 reframed → **docs-only finding** (doyle publishing syntax, PR #13). ADR-0001 dependency **SATISFIED**.
5. Authored first two bodies (`whoami`, `setup`) as `adapter/strings/skills/*.md` + `{ file }` pointers, grounded in public surface (`spt whoami`, shipped bootstrap). Extended `registration-int.sh` → **8/8** proving resolve vs live binary.

**Commits** (all gates PASS, traceable green): `f84acc0` → `04d6c35` → `ca41f8b`.

**Bus:** doyle + todlando looped, all acked. F-003 closed both legs.

## Next (in plan)
- Per-skill body conversions (commune/live/ready/send/signoff/version) — ready+send **delegate to `spt how-to`**.
- **Real operative blocker** = UPS hook only *drains inbox* today; skill-injection branch (`/sptc:X` → inject `get-string skills.<x>`) **unbuilt**, gated on open empirical Q: *does CC UserPromptSubmit fire on `/slash`?* (throwaway live-CC test). REQ-UPS-INJECTION int held on it.
- Still owed: REQ-MSG-ENVELOPE byte-capture when todlando merges PR #12 (`<EVENT>` everywhere).

Perch live, staying reachable.

# Adapter-manifest + M12 parity — JIT plan (next milestone)

> Fresh milestone after the CI/distribution slices. Authors the CC adapter **manifest** (publish
> target #2, the spt-core registry side) against the REAL v0.7.0 published surface, then the M12
> parity surfaces. NEEDS public-docs research first — run in clean context.

## Public-surface-only (hard constraint — re-read)

Build ONLY from `SaberMage/spt-releases` (v0.7.0) + `https://sabermage.github.io/spt-releases`
(harness-contract, CLI reference, manifest.schema.json, rustdoc, llms-full.txt). NEVER read
spt-core source. A missing capability = a FINDING for doyle/todlando, not a workaround. (AGENTS.md)

## Research first (before authoring)

1. Pull v0.7.0 `manifest.schema.json` from spt-releases — the authoritative shape the adapter
   manifest must validate against. Note required fields, `[adapter]` block, `[strings]` (file-backed
   large bodies), `shortcut_basename`, profiles/hints/`[digest]` extractor.
2. Read the published harness-contract + CLI reference for: `spt adapter` registration verbs,
   `spt endpoint run`, `shortcut_basename` semantics (emits `sptc-<id>` shortcuts), whoami-as-alias,
   adapter:profile fallback addressing.
3. Confirm where the manifest physically lives (spt-core-conducted registry, NOT plugin files —
   ADR-0001/SCOPE) and how it's validated locally.

## Slices (sequence; each its own commit + green gate)

1. **DONE (bd16644)** — **Adapter manifest authoring**. `adapter/claude-spt.toml` ([adapter]+
   shortcut_basename, [hooks.*], [identity], [inject], [digest], [profiles.deep], [strings],
   [[hints]]); vendored `adapter/manifest.schema.json`; manifest-schema gate
   (`ci/manifest/{validate_manifest.py,check-manifest.sh}`, py tomllib|tomli + jsonschema) wired
   into `run-gates.sh`. **REQ-DIST-MANIFEST-SCHEMA** → `[doc,impl,unit]` (int held: real
   `spt adapter add` registration-validation = 2nd layer). Deferred in-manifest with notes:
   `[session]`/roles, `[history]`, `[update]` (file_pull needs a signing key + registry repo not
   on the public surface — a finding).
2. **DONE (c93757d)** — **shortcut_basename** guard. `tests/manifest-shortcut.sh` asserts the
   `sptc` brand (succession seam). **REQ-DIST-SHORTCUT-BASENAME** → `[doc,unit]` (the field is
   declarative config, not impl — the scanner classifies impl by file type; launcher impl +
   real-picker int deferred to the endpoint-run/cc-launcher slice, gated on the v0.7.0 binary).
3. **M12 parity surfaces** (seed REQs per surface as each starts — activate-don't-pre-fail):
   - **DONE (8cd8372)** — `/sptc:whoami` + `/sptc:setup` skill skeletons (the manifest advertised
     both; skeletons now exist, covered by REQ-DIST-PLUGIN-SKELETON + skeleton-validate).
   - **DONE (435e1be)** — **manifest proven against live v0.7.0**. Local spt upgraded to 0.7.0;
     `ci/manifest/registration-int.sh` (SPTC_ACCEPTANCE-gated) green 6/6: `spt adapter add`
     accepted (2nd-layer cross-field validation), shipped `:deep` profile resolves, `[strings]`
     read + overlay observable via `get-string`, clean soft-remove. **REQ-DIST-MANIFEST-SCHEMA →
     [doc,impl,unit,int]**. Cross-field discovery fixed: `[digest]` needs `source` →
     `source="{home}/.claude/projects"`. Findings logged (key catalog + digest rule undocumented).
   - **IN PROGRESS — capability confirmed (F-003 resolved 2026-06-15)** — file-backed `[strings]`.
     Research conclusion REVERSED by live byte-test + doyle/todlando ruling: the mechanism **is
     shipped** in v0.7.0 as a value-position table pointer `key = { file = "rel" }` over
     `adapters/<adapter>/strings/` (lazy-resolved at `get-string`, containment-checked, copied on
     `adapter add`). My avenue search missed it (it's a value-table shape, not a CLI verb / `@file`).
     ADR-0001 dependency **SATISFIED**; residual is docs-only (doyle publishing, PR #13).
     - **DONE (this session)** — pattern proven end-to-end + first two bodies authored:
       `adapter/strings/skills/{whoami,setup}.md` + `[strings.skills].{whoami,setup} = { file = ... }`;
       `registration-int.sh` extended (8/8) — asserts a `{ file }` pointer resolves to FILE CONTENTS
       and an inline sibling prints as-is, vs live v0.7.0. `strings/` resolves next to the manifest

     - **TODO (per-skill increments)** — convert the remaining inline summaries (commune, live, ready,

     - **NOT this slice (separate, REQ-UPS-INJECTION):** the UPS hook only *drains the inbox* today
       (`user-prompt-submit.sh`: `api poll` → `render_frames`); the **skill-body injection branch**
       (detect `/sptc:X` → inject `get-string skills.<x>`) is **unbuilt**, and its gate — *does CC's
       UserPromptSubmit even fire on a `/slash` prompt?* — is still ADR-0001's open empirical question
       (throwaway live-CC byte-test). That, not the manifest source, is the real blocker for operative
       skills. `REQ-UPS-INJECTION` int stays held on it. The whoami/setup SKILL.md stubs still say
       "held pending … M12 file-backed `[strings]`" — that clause is now stale (capability shipped);

   - **TODO** `[session.self]` + `spt endpoint run` bringup + `cc`/`sptc` launcher → unblocks the
     held **REQ-DIST-SHORTCUT-BASENAME** impl+int (the `<basename>-<id>` picker "lands in a later
     spt-core wave" per `endpoint run --help`; `endpoint run` spawns `[session.self]`, still deferred).
   - **TODO** digest extractor binary `claude-spt-digest` → unblocks `spt adapter digest-proof`
     (the deeper [digest] int; the seam is declared + registration-accepted, extractor unbuilt).

### Still held on spt-core (non-blocking)
- `sptc-<id>` shortcut EMISSION — spt-core picker wave (not in 0.7.0) + needs `[session.self]`.
- REQ-MSG-ENVELOPE poll→additionalContext bus-delivery int — doyle pings for byte-capture when
  todlando lands the ADR-0020 relic removal; I owe a confirm-match + a HOOKS-API/UPS-INJECTION int flip.

### Note: claude-spt is now a REGISTERED adapter artifact on this node (the v1 acceptance proof).
The int test soft-removes it each run; re-add with `spt adapter add adapter/claude-spt.toml`.
Local `spt` is **0.7.0** (operator-upgraded 2026-06-15).

# Adapter-manifest + M12 parity — JIT plan (next milestone)

> Fresh milestone after the CI/distribution slices. Authors the CC adapter **manifest** (publish
> target #2, the spt-core registry side) against the REAL v0.7.0 published surface, then the M12
> parity surfaces. NEEDS public-docs research first — run in clean context.

## Public-surface-only (hard constraint — re-read)

Build ONLY from `SaberMage/spt-releases` (v0.7.0) + `https://sabermage.github.io/spt-releases`
(harness-contract, CLI reference, manifest.schema.json, rustdoc, llms-full.txt). NEVER read
spt-core source. A missing capability = a FINDING for doyle/todlando, not a workaround. (AGENTS.md)

## Research first (before authoring)

1. Pull v0.7.0 `manifest.schema.json` from spt-releases — the authoritative shape the adapter
   manifest must validate against. Note required fields, `[adapter]` block, `[strings]` (file-backed
   large bodies), `shortcut_basename`, profiles/hints/`[digest]` extractor.
2. Read the published harness-contract + CLI reference for: `spt adapter` registration verbs,
   `spt endpoint run`, `shortcut_basename` semantics (emits `sptc-<id>` shortcuts), whoami-as-alias,
   adapter:profile fallback addressing.
3. Confirm where the manifest physically lives (spt-core-conducted registry, NOT plugin files —
   ADR-0001/SCOPE) and how it's validated locally.

## Slices (sequence; each its own commit + green gate)

1. **DONE (bd16644)** — **Adapter manifest authoring**. `adapter/claude-spt.toml` ([adapter]+
   shortcut_basename, [hooks.*], [identity], [inject], [digest], [profiles.deep], [strings],
   [[hints]]); vendored `adapter/manifest.schema.json`; manifest-schema gate
   (`ci/manifest/{validate_manifest.py,check-manifest.sh}`, py tomllib|tomli + jsonschema) wired
   into `run-gates.sh`. **REQ-DIST-MANIFEST-SCHEMA** → `[doc,impl,unit]` (int held: real
   `spt adapter add` registration-validation = 2nd layer). Deferred in-manifest with notes:
   `[session]`/roles, `[history]`, `[update]` (file_pull needs a signing key + registry repo not
   on the public surface — a finding).
2. **DONE (c93757d)** — **shortcut_basename** guard. `tests/manifest-shortcut.sh` asserts the
   `sptc` brand (succession seam). **REQ-DIST-SHORTCUT-BASENAME** → `[doc,unit]` (the field is
   declarative config, not impl — the scanner classifies impl by file type; launcher impl +
   real-picker int deferred to the endpoint-run/cc-launcher slice, gated on the v0.7.0 binary).
3. **M12 parity surfaces** (seed REQs per surface as each starts — activate-don't-pre-fail):
   - **DONE (8cd8372)** — `/sptc:whoami` + `/sptc:setup` skill skeletons (the manifest advertised
     both; skeletons now exist, covered by REQ-DIST-PLUGIN-SKELETON + skeleton-validate).
   - **DONE (435e1be)** — **manifest proven against live v0.7.0**. Local spt upgraded to 0.7.0;
     `ci/manifest/registration-int.sh` (SPTC_ACCEPTANCE-gated) green 6/6: `spt adapter add`
     accepted (2nd-layer cross-field validation), shipped `:deep` profile resolves, `[strings]`
     read + overlay observable via `get-string`, clean soft-remove. **REQ-DIST-MANIFEST-SCHEMA →
     [doc,impl,unit,int]**. Cross-field discovery fixed: `[digest]` needs `source` →
     `source="{home}/.claude/projects"`. Findings logged (key catalog + digest rule undocumented).
   - **IN PROGRESS — capability confirmed (F-003 resolved 2026-06-15)** — file-backed `[strings]`.
     Research conclusion REVERSED by live byte-test + doyle/todlando ruling: the mechanism **is
     shipped** in v0.7.0 as a value-position table pointer `key = { file = "rel" }` over
     `adapters/<adapter>/strings/` (lazy-resolved at `get-string`, containment-checked, copied on
     `adapter add`). My avenue search missed it (it's a value-table shape, not a CLI verb / `@file`).
     ADR-0001 dependency **SATISFIED**; residual is docs-only (doyle publishing, PR #13).
     - **DONE (this session)** — pattern proven end-to-end + first two bodies authored:
       `adapter/strings/skills/{whoami,setup}.md` + `[strings.skills].{whoami,setup} = { file = ... }`;
       `registration-int.sh` extended (8/8) — asserts a `{ file }` pointer resolves to FILE CONTENTS
       and an inline sibling prints as-is, vs live v0.7.0. `strings/` resolves next to the manifest
       FILE on `adapter add`. Bodies grounded in the public surface (`spt whoami`; shipped bootstrap).
     - **TODO (per-skill increments)** — convert the remaining inline summaries (commune, live, ready,
       send, signoff, version) to file-backed bodies as each is authored. ready/send should **delegate
       to `spt how-to ready|send`** (published agent guidance) rather than duplicate.
     - **NOT this slice (separate, REQ-UPS-INJECTION):** the UPS hook only *drains the inbox* today
       (`user-prompt-submit.sh`: `api poll` → `render_frames`); the **skill-body injection branch**
       (detect `/sptc:X` → inject `get-string skills.<x>`) is **unbuilt**, and its gate — *does CC's

       "held pending … M12 file-backed `[strings]`" — that clause is now stale (capability shipped);
       refresh when the injection branch lands.
   - **TODO** `[session.self]` + `spt endpoint run` bringup + `cc`/`sptc` launcher → unblocks the
     held **REQ-DIST-SHORTCUT-BASENAME** impl+int (the `<basename>-<id>` picker "lands in a later

   - **TODO** digest extractor binary `claude-spt-digest` → unblocks `spt adapter digest-proof`
     (the deeper [digest] int; the seam is declared + registration-accepted, extractor unbuilt).

### Still held on spt-core (non-blocking)

b89c22e committed, gates green. doyle: "carry on" — unblocked on everything else.

## Session wrap

5 commits, all gated (PASS + traceable green):
- `f84acc0` F-003 filed
- `04d6c35` F-003 resolved (capability shipped, docs-only residual)
- `ca41f8b` first file-backed skill bodies (whoami, setup) + int 8/8
- `b89c22e` REQ-MSG-ENVELOPE held on publish-not-merge (ADR-0020 merged `25ffd7a`)

Net: file-backed `[strings]` proven shipped + first bodies authored. Cross-team findings closed. Repo notes hardened against premature int flip.

## Two candidate next slices (both fresh focused work)
1. **UPS injection branch** — build `/sptc:X` → inject `get-string skills.<x>` in `user-prompt-submit.sh`. Needs the empirical test first: *does CC UserPromptSubmit fire on a `/slash` prompt?* (live-CC throwaway). Gates REQ-UPS-INJECTION int + makes whoami/setup operative end-to-end.
2. **`claude-spt-digest` extractor** — build the binary (contract known: `{role,text,tool,ts}` JSONL, CC JSONL → records). Unblocks `spt adapter digest-proof`.

Pick one and I continue. Perch live, reachable.


on 1: you already proved this in a previous session. iirc the results were recorded in the docs here somewhere. but tl;dr yes, CC UserPromptSubmit DOES fire on slash commands.

140	- No spt-core dependency for the wiring itself — only the (non-blocking) residual docs publish of the

142

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.

## Validation results (throwaway `claude -p` session, 2026-06-15)

Ran an isolated temp-project rig (UserPromptSubmit marker hook + a registered `/send` project
skill) on the real CC 2.1.177 binary:

- ✅ **UPS fires on a `/`-slash-command.** `MSYS_NO_PATHCONV=1 claude -p "/send hi"` → the hook
  received `prompt:"/send hi"` (literal) **and** fired **and** the skill ran. Answers the
  SCOPE-flagged question: `UserPromptSubmit` fires on a `/sptc:X` invocation with the token intact,
  so the wrapper can detect `/sptc:X` in `prompt` and inject. (`REQ-UPS-INJECTION`.)
- ✅ **Windows `shell:"bash"` command hooks work** — the hook executed via Git-Bash,
  `$CLAUDE_PROJECT_DIR` resolved, exit-0 stdout honored. Resolves Open#2 for the POSIX-wrapper
  packaging on Windows (no per-OS branch needed for the hook to run).
- ✅ **Hook stdin schema confirmed**: `{session_id, transcript_path, cwd, permission_mode,
  hook_event_name, prompt}` — `json_str` targets the right fields; `session_id` sourcing confirmed.
- ⚠ **MSYS `/`-arg mangling** observed (run A): a `/send` passed as a Git-Bash *argument* became
  `C:/Program Files/Git/send`. Test artifact (wrappers read stdin, not argv) but a real Windows
  hazard → `docs/KNOWN-HAZARDS.md` 1.1 + `REQ-HAZARD-MSYS-PATHCONV` (test: `tests/msys-hazard.sh`).

## Open (remaining `int` — gated on the spt-core poll refactor)

1. **`api poll` → `additionalContext` round-trip** against a real spt perch, once `REQ-MSG-ENVELOPE`
   lands (poll emits `<EVENT>`): capture actual stdout bytes, confirm-match to doyle, flip `int`.
2. **Large-drain injection size** — CC `additionalContext` caps at 10k chars; add truncate/spill in
   the UPS wrapper (adapter-side; `int`).

## 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.


Confirmed — you're right. ADR-0002 §Validation (2026-06-15) records it: ✅ **UPS fires on `/`-slash-command, token intact** (`prompt:"/send hi"` literal, hook fired, skill ran), stdin schema `{session_id,...,prompt}` confirmed. My "still-open empirical" framing was stale. The skill-injection branch is **buildable now** — the only spt-core dep was file-backed strings (F-003, now shipped).

So slice 1 is real, unblocked work. Let me build it. First read the hook helpers + current wiring.

Clear structure. Building the skill-injection branch now: add `sptc_skill_key` (pure, extract `/sptc:<skill>`) + `sptc_inject_skill` (resolve body via get-string) to `_common.sh`, wire into the UPS hook *before* the perch check (whoami/setup need no perch), add unit tests, extend the int. Read `_common.sh` via Read tool for exact edit anchors.
