//! v0.13.0 P2 (REQ-SESSION-RESUME-TEMPLATE) — the real-fixture gate for the
//! resume-blank ship-blocker. Root cause: spt-core had `[session.self]` (fresh)
//! but no `[session.resume]` native-resume sibling, so `--resume` re-ran the
//! FRESH command → the harness started a blank transcript.
//!
//! This drives the SAME real spt-hosted bringup as `dummy_harness_e2e.rs` —
//! `spt endpoint run --start` → broker PTY → the dummy harness — against a REAL
//! detached `spt daemon run`, with a dummyharness adapter whose `[session.resume]`
//! command DIFFERS from `[session.self]`. The dummy writes a MARKER file recording
//! (a) which template launched it (`self` vs `resume`) and (b) the `current_dir()`
//! it landed in. We assert:
//!   - a FRESH `endpoint run --start` (no `--resume`) writes the SELF marker, and
//!     the RESUME marker is ABSENT;
//!   - a `--resume <session>` `endpoint run --start` writes the RESUME marker
//!     (proving template SELECTION), and the recorded cwd matches the cwd the
//!     bringup landed in (proving the cwd plumbing).
//!
//! Both bringups use `--start` (detached, return-now) — no attach pump — so the
//! marker file is the deterministic proof, with no PTY-output capture race. The
//! marker is written into the isolated SPT_HOME (always writable regardless of
//! the harness cwd); its CONTENTS carry the harness `current_dir()` so the cwd
//! assertion is independent of where the marker file itself lives.
//!
//! Bounded; all spawned pids reaped SCOPED (never machine-wide — shared runner).

- Resume run → `resume` template selected, and the recorded cwd matches the launch cwd
- The resume session id `resumed-session-xyz` is forwarded through (visible in `session=resumed-session-xyz`)

Now let me verify the int test would catch the bug — mutation-check by forcing `is_resume=false` in cli.rs so the resume re-runs the fresh template (the exact original bug).


cd /c/Users/decid/Documents/projects/spt-core
cp crates/spt/src/cli.rs /tmp/cli.bak
# Reproduce the ORIGINAL BUG: force is_resume=false so --resume re-runs [session.self]
python - <<'EOF'
p="crates/spt/src/cli.rs"
s=open(p).read()
mut=s.replace("    let is_resume = resume.is_some();","    let is_resume = false; // MUTATION: original resume-blank bug")
assert mut!=s
open(p,"w").write(mut)
EOF
cargo test -p spt --test resume_template_e2e -- --test-threads=1 2>&1 | grep -E "test result|FAILED|resume-template SELECTION|panicked" | head -6
cp /tmp/cli.bak crates/spt/src/cli.rs

The int test correctly goes RED when the resume-blank bug is reintroduced, and GREEN on the real impl. This is a high-value regression guard against exactly the ship-blocker bug.

=== is driven_by_selfheal among my changes? ===
warning: in the working copy of 'crates/spt-runtime/manifest.schema.json', LF will be replaced by CRLF the next time Git touches it
NO — driven_by_selfheal.rs is NOT a file I touched


`driven_by_selfheal.rs` is not in my change set — the working tree already had impl changes (cli.rs, picker, startup, digest, etc.) before I started, which is expected since "the implementation is COMPLETE." But I notice `manifest.schema.json` was modified. The schema drift gate may have already been blessed by the implementer, or it may now reflect my `resume` field addition. Let me check: the failing `driven_by_selfheal` test is a pre-existing concern. Let me confirm it fails on a stash of only-mine changes — actually, it's not a file I touched and not related to resume. Let me verify it's pre-existing by checking if my edits could affect it (they can't — it's about controller_by reconcile).

Let me confirm this test was already failing before my work by stashing my changes and running it.


cd /c/Users/decid/Documents/projects/spt-core

The grep matched nothing — the stash only reverted my 4 files, but the *other* working-tree impl changes (cli.rs, startup.rs, etc.) remained, so the test binary may not have rebuilt the same way. The output was empty, suggesting it compiled/ran without my changes but grep caught nothing useful. Let me run it directly and fully to see the real state, and check whether this is a known-flaky/already-failing test independent of my work.

Run single-threaded, both tests in `driven_by_selfheal` pass. The earlier failure was a **test-isolation / parallelism flake**, not a real defect — this is a daemon e2e test that mutates shared process/perch state and is not isolated under the default parallel runner. The spt-daemon integration tests (`driven_by_selfheal`, etc.) require `--test-threads=1`, consistent with my memory notes that these daemon/broker e2e tests need serialization.

Let me re-run the full lib-crate test suites single-threaded to get a clean signal, confirming nothing I added regressed.

       User-facing CLI output is human-readable: DIRECT-USER commands (e.g. adapter update/list/use) render friendly prose instead of raw CODE:RESULT markers — "claude-spt is up to date (0.2.0)." not "ADAPTER_UPDATE_UPTODATE:claude-spt: installed 0.2.0, latest 0.2.0". Strictly bounded to the direct-user surface: the adapter-PARSED bringup tokens (SEEDED/BOUND/READY/NO_SEED on seed/listen, which adapters grep) stay machine-parseable — humanization is additive (a human line beside the marker, or a --porcelain/--quiet split), never a silent rename of a dual-contract marker. The user-facing bringup composition belongs to the adapter (perri); this REQ owns only the direct-user CLI surface. (v0.9.0)

The markers are STRIPPED either way — a raw `**` or backtick must NEVER reach the user (the operator-reported v0.12.0 defect: help text reads `**ctrl-b**` and stray backticks verbatim). Color/bold escapes are emitted ONLY when the help is going to a real terminal AND color is not suppressed (NO_COLOR unset · CLICOLOR != 0 · CLICOLOR_FORCE forces on); a pipe / redirect / CI / NO_COLOR falls back to strip-only (clean plaintext, zero escapes) so machine-readable help is byte-identical regardless of marker syntax. Pure transform over the clap-rendered help string at the single run()/bare_invocation chokepoint; preserves pre-existing ANSI (CSI sequences passed through untouched), never spans markers across a newline, leaves unmatched/empty markers literal, and does not alter the help layout. (v0.12.1)
  [OK] REQ-CLI-OUTPUT-MARKDOWN  required: [impl, unit]  stages: -doc +impl +unit -int
       Human-prose COMMAND OUTPUT (not just `--help`) renders the inline Markdown authored in its source strings as terminal styling, never literal markers: `` `code` `` → ANSI cyan, `**bold**` → ANSI bold, `[text](url)` → `text`, markers STRIPPED either way. REQ-CLI-HELP-MARKDOWN only hooked the clap `--help` chokepoint, so command output still printed raw Markdown (audit: `spt how-to` topic text showed `# headers`/backticks, `spt subnet`/`subnet status` hint footers showed stray backticks, the daemon-status `not running` line, the `ENDPOINT_RUN_STARTED` attach hint, and the daemon's `SUBNET_DETACHED` startup line — 13 prose surfaces). The same line-bounded pure `helpfmt::render` is applied at each emit site, color-gated by the OUTPUT STREAM's own tty (`stdout_color` for print/println, the new `stderr_color` for eprintln). HARNESS-SAFETY (binding): color is tty-gated, so an adapter (piped / non-tty / NO_COLOR) gets STRIP mode = zero ANSI + markers removed; every dual-contract MACHINE token on a rendered line (`ENDPOINT_RUN_STARTED:`, `NO_SUCH_TOPIC:`, `SUBNET_DETACHED:`) carries NO Markdown markers, so it survives strip byte-intact — the adapter parse is never perturbed. Pure-machine output (the `<EVENT …>` envelope, bringup parse-tokens SEEDED/BOUND/READY/NO_SEED, `--json`, QR) is NEVER routed through the renderer. The one spt-daemon source string (`SUBNET_DETACHED`, the bin-local renderer is unreachable from the daemon crate) is authored marker-free instead. (v0.12.2)

  [OK] REQ-SESSION-RESUME-TEMPLATE  required: [doc, impl, unit, int]  stages: +doc +impl +unit +int
       Resuming an endpoint session that HAS conversation history brings up a BLANK session. ROOT (doyle, code-grounded + CONTEXT — case-3 spt-core MISSING feature, NOT a perri docs-miss): CONTEXT L127-129 already defines the resume-session seam ('continue-existing: resume an existing harness session under the adapter — its NATIVE resume'), and the manifest already has the resume-variant pattern (Session has BOTH psyche_init AND psyche_resume, manifest.rs:217-219) — but the agent's own session has ONLY self_ (`[session.self]`, no resume sibling). cmd_endpoint_run (cli.rs:1304) re-passes the session_id through `[session.self]` on resume (resume.unwrap_or_else(mint_session_id)), so the adapter's FRESH command (e.g. `claude --session-id ..`) runs again instead of the harness NATIVE resume (`claude -r ..`) -> CC starts a fresh transcript -> blank. spt-core forwards session_id + cwd faithfully; it just has no way to express the native-resume invocation. SECOND GAP: CC resolves a transcript by session_id + cwd, but the session ledger records only {ts, session_id, trigger} (no cwd), so picker Resume-from-history (cross-project rows) can't restore the right cwd. FIX (doyle design, V0.13.0-P2-SESSION-RESUME-DESIGN.md, mirrors psyche_init->psyche_resume exactly): (A) add a `[session.resume]` role (resume: Option<SessionRole> on Session + roles()/is_empty()); cmd_endpoint_run selects it when --resume is set AND it's declared (fill {id}/{session_id}=resumed id/{session_name} + the resume cwd), else FALL BACK to `[session.self]` (full back-compat). (B) record cwd PER ledger row (operator ruling): {ts, session_id, trigger, cwd} additive serde-default; resume cwd = resumed row cwd -> else perch info.cwd -> else current_dir (back-compat for old rows + single-project endpoints); picker threads the selected row's cwd through Outcome::Run -> cmd_endpoint_run. (C) public docs (MANIFEST + harness-contract) teach `[session.resume]` so perri builds the adapter side BLIND. Adapter follow-on (perri, AFTER spt-core ships+docs): declare `[session.resume] command = claude -r {session_id} --remote-control {id} --dangerously-skip-permissions` from the resume cwd. Completes REQ-READY-AGENT-RESUME / REQ-RUN-PICKER resume-from-history. (v0.13.0)

REQ-SESSION-RESUME-TEMPLATE shows `+doc +impl +unit +int` — all four stages covered, overall exit 0.

All gates pass. Let me do a final confirmation run of just the new int test (clean, threaded as it runs in CI) plus the three new/extended unit test names together, to present clean evidence.

All green. Let me update my memory with the resume-template int-test fixture pattern, since it's a reusable harness-bringup proof technique worth keeping.

metadata:

To prove WHICH session template the real spt-hosted bringup selected (and the cwd
the harness landed in) end-to-end, extend `adapters/mock/src/main.rs --mode dummy`
with a `--marker-file <path>` flag (+ a `--resume-marker` discriminator token): the
dummy writes `template=<self|resume>\ncwd=<current_dir()>\n` BEFORE its heartbeat
loop. The int test (`crates/spt/tests/resume_template_e2e.rs`) registers a
`dummyresume` adapter declaring `[session.self]` (writes a SELF marker path) AND a
DISTINCT `[session.resume]` (writes a DIFFERENT RESUME marker path + `--resume-marker`),
then:
- fresh `endpoint run --start` (no --resume) → poll for the SELF marker, assert RESUME
  marker ABSENT.
- `endpoint run --resume <sid> --start` → poll for the RESUME marker; assert
  `template=resume` and the recorded `cwd` == the launch cwd (canonicalized both sides
  to absorb Windows 8.3 / symlinked-tempdir / trailing-sep differences).

Why marker file, not PTY-output capture: BOTH bringups use `--start` (detached,
return-now) so there is NO attach pump and NO PTY-output race — the marker file is the
deterministic proof, and its CONTENTS carry the harness cwd so the cwd assertion is
independent of where the marker file itself lives (put it under SPT_HOME/markers, always
writable). This sidesteps the ConPTY injected-echo-loss problem entirely (see
[[conpty-injected-echo-loss]]).

Determinism trick (reused from the ONLINE-RACE test): between the two runs, KILL the
fresh harness and poll info.status to STATUS_OFFLINE before the resume run, so the resume
is a clean second spawn not racing the first. Same isolated-SPT_HOME + scoped full-tree
reap (rc/run → both harness incarnations → {id}-psyche → daemon stop → brain → broker) as
[[spt-test-conventions]] dummy_harness_e2e.

Mutation-proven: forcing `is_resume=false` in cli.rs (the original resume-blank bug)
makes the int test RED at the `template=resume` assertion; the real impl is GREEN.

RUNNER GOTCHA: spt-daemon integration tests (e.g. `driven_by_selfheal`) FLAKE under the
default parallel runner (shared perch/process state) — `gap_a_...` falsely FAILED under
`cargo test -p spt-daemon` but PASSES under `--test-threads=1`. Always run the daemon +
spt e2e suites single-threaded; a lone parallel failure there is almost certainly an
isolation flake, not a regression. Verify by re-running that one test with
`-- --test-threads=1` before treating it as real.

SERDE back-compat note: a missing `Option<T>` field deserializes as `None` even WITHOUT
`#[serde(default)]` (serde implicit-Option). So the ledger `cwd` back-compat is
structurally guaranteed by the Option type; `#[serde(default)]` there is load-bearing
only for non-Option additive fields. The back-compat unit asserts the OBSERVABLE contract
(old no-cwd row → None, new row → Some) which still guards against anyone changing `cwd`
to a required non-Option field.

All work complete and gates green. Here is the report.

## Summary — REQ-SESSION-RESUME-TEMPLATE unit + int coverage

All tests written, all gates pass, no production behavior changed. Mutation-proven against the original resume-blank bug. **Not committed** (per your instruction — yours to gate-review).

### Files touched

**Tests added (unit):**
- `C:\Users\decid\Documents\projects\spt-core\crates\spt-runtime\src\manifest.rs` — added `session_resume_role_parses_roundtrips_and_is_backcompat`
- `C:\Users\decid\Documents\projects\spt-core\crates\spt-daemon\src\harnesshost.rs` — added helper `harness_manifest_with_resume` + `prepare_selects_resume_template_on_resume_else_self` + `prepare_resume_falls_back_to_self_when_no_resume_role`
- `C:\Users\decid\Documents\projects\spt-core\crates\spt-store\src\sessions.rs` — added `row_with_cwd_appends_and_reads_back`, `pre_migration_row_without_cwd_deserializes_as_none`, `none_cwd_emits_no_field_and_roundtrips`

**Test added (int):**
- `C:\Users\decid\Documents\projects\spt-core\crates\spt\tests\resume_template_e2e.rs` (new file) — `endpoint_run_resume_selects_resume_template_in_recorded_cwd`

**Mock extension (minimal, additive):**
- `C:\Users\decid\Documents\projects\spt-core\adapters\mock\src\main.rs` — `--mode dummy` gained an optional `--marker-file <path>` (+ `--resume-marker` discriminator). When set, writes `template=<self|resume>\ncwd=<current_dir()>\n`. Absent ⇒ unchanged dummy behavior (the existing `dummy_harness_e2e` still passes).

### What each test guards

- **manifest unit:** `[session.resume]` parses (distinct command), `roles()` orders `resume` immediately after `self`, `is_empty()` false when only `resume` set, round-trip stable, and a no-`[session.resume]` manifest parses with `resume: None` and emits no resume table (back-compat).
- **harnesshost unit:** with both roles declared, `is_resume=true` fills the RESUME command and `is_resume=false` fills SELF (different argv); and `is_resume=true` with NO resume role falls back to SELF (back-compat, not an error).
- **sessions unit:** a row with `cwd: Some` round-trips; a raw pre-migration JSONL row `{ts,session_id,trigger}` (no `cwd`) deserializes with `cwd: None` alongside a new-shape row; a `None` cwd emits no `cwd` key.
- **int (real daemon+broker+PTY):** fresh `endpoint run --start` runs `[session.self]` (SELF marker, RESUME absent); `--resume <id> --start` runs `[session.resume]` (RESUME marker, `template=resume`) and lands in the recorded/launch cwd (canonicalized compare). Both bringups detached (`--start`), so the marker file is the deterministic proof — no PTY-output capture race.

### Human-usage scenarios covered
- Adapter author who never declares `[session.resume]` (the entire existing fleet) — must keep working: covered by both manifest and harnesshost fallback units, and the int test's behavior is back-compat by construction.
- Old on-disk session ledger written before the `cwd` field existed — must still load: the pre-migration raw-JSONL unit.
- The exact operator bug ("resume shows a blank session"): the int test reproduces the real bringup and asserts the resume template (not the fresh one) ran.

### Mutation verification (proves the tests can fail)
- Forcing `is_resume=false` in `cli.rs` (the original bug) → int test RED at `template=resume`.
- Inverting the role selection in `harnesshost.rs` → `prepare_selects_resume_template…` RED.
- Real impl → all GREEN.

### Gate command outputs (all PASS)
- `cargo test -p spt-runtime -p spt-store -p spt-daemon -- --test-threads=1` → **ok** (runtime 74, store 170, daemon 343 + all int suites 0 failed)
- `cargo test -p spt --test resume_template_e2e -- --test-threads=1` → **ok. 1 passed**
- `cargo clippy --workspace --all-targets -- -D warnings` → **Finished, 0 warnings**
- `cargo run -p xtask -- check` → **xtask check: OK** (docs-drift not regressed)
- `traceable-reqs check` → **exit 0**; `REQ-SESSION-RESUME-TEMPLATE` shows `+doc +impl +unit +int`

### One thing worth flagging (not a defect, a runner caveat)
Under the default *parallel* runner, `cargo test -p spt-daemon` showed a spurious failure in `driven_by_selfheal::gap_a_…` (a daemon e2e that mutates shared perch/process state). Run single-threaded it passes cleanly. The spt-daemon and spt e2e suites must run with `--test-threads=1` (consistent with the dummy-harness e2e convention). No product defect — purely test isolation under parallelism. I recorded this in agent memory.

### Gaps intentionally left
- I did **not** add picker model units (`ResumeRow::title`, `resume_outcome` cwd threading) — per your brief, the implementer already updated those (`resume_outcome_bakes_session` and the title units already reference the new `cwd` field + the `{head} - {local_time} (…{id5})` shape). I verified they exist and compile; not duplicated.

No product bugs uncovered — the implementation matches the design spec.
