Convert `tasks.md` to `tasks.json` + +Each migrated bundle's `tasks.md` (v2 markdown checklist format) is +parsed by `_parse_v2_tasks_md` and converted to a v3 `tasks.json` file. +The original `tasks.md` is deleted. + +The parser handles `- [ ]`, `- [~]`, and `- [x]` checkbox lines with +optional trailing `@session` attribution. IDs are assigned sequentially +as `t-001`, `t-002`, ... scoped to the migrated bundle. + +The migration applies to bundle-level `tasks.md` only.

Warnings are logged but do not +abort the receive. + +The result is also threaded back to callers via the `migration` key on +`receive_package`'s return dict (alongside `source_layout` so non-v2 +receives are easy to recognise — the value is `None` for v3/agnostic +packages): + +```python +result = receive_package(...) +if result["source_layout"] == "v2": + print("Migrated", len(result["migration"]["bundles_migrated"]), + "bundles, converted", result["migration"]["tasks_converted"], + "tasks") +``` + +## Preview surfacing + +When the receive pipeline runs migration (LD1 step 6), the `migrate_v2_layout` +result dict is rendered as a bordered block ABOVE the standard preview at +LD1 step 7.

This is not an error — it +just means the package had no bundles. + +### Missing `tasks.md` in a bundle + +If a migrated bundle has no `tasks.md`, no `tasks.json` is created. The +bundle is still added to `bundles_migrated`. v3 bundles are allowed to +have empty task state. + +### Multiple `_kernel/` files + +The migration only touches `_kernel/_generated/`. Other `_kernel/*` files +(`key.md`, `log.md`, `insights.md`, `tasks.json`, `completed.json`, +`config.yaml`) are passed through unchanged. The receiver decides what +to do with each per LD18 scope semantics. + +### `_kernel/_generated/` is a regular file + +If `_kernel/_generated` exists as a regular file rather than a directory, +the migration leaves it alone and records a warning. This shouldn't +happen with a well-formed sender, but the migration is defensive. + +### Existing `tasks.json` in a v2 bundle + +If a v2 bundle somehow has BOTH `tasks.md` AND `tasks.json` (corrupted +sender), the migration leaves `tasks.json` untouched and deletes the +`tasks.md`. A warning is recorded. The receiver inherits whatever was in +`tasks.json`. + +## Failure semantics + +A migration failure aborts the receive WITHOUT touching the target +walnut. The pipeline: + +1. Catches `errors[]` from `migrate_v2_layout`. +2.

The CLI subcommand `receive` is a thin +wrapper that translates exceptions to exit codes. + +``` +INPUT → 1. extract → 2. validate → 3. dedupe-check → 4. infer-layout + → 5. scope-check → 6. migrate → 7. preview → 8. acquire-lock + → 9. transact-swap → 10. log-edit → 11. ledger-write + → 12. regenerate-now → 13. cleanup-and-release +OUTPUT +``` + +Steps 1-8 are pre-swap: a failure aborts cleanly without touching the +target. Step 9 is the atomic swap. Steps 10-12 are post-swap and NON-FATAL +(unless `--strict`). Step 13 always runs via `try/finally`. + +--- + +## Step 1 — extract + +**Purpose:** detect the envelope, decrypt if needed, and extract the +plaintext payload into a staging directory on the SAME filesystem as the +target. Same-filesystem matters because step 9 uses `shutil.move` which is +atomic across same-filesystem renames but a copy+delete across filesystems. + +**Envelope detection (LD21):** +- First two bytes `1F 8B` → unencrypted gzipped tarball. +- First eight bytes `Salted__` → OpenSSL passphrase envelope. +- Otherwise, opens the file as a tar archive and looks for either + `rsa-envelope-v1.json` (LD21 canonical RSA hybrid, lands in .11) or + `payload.key` + `payload.enc` (legacy v2 RSA hybrid). +- Anything else raises `ValueError("Unknown package format")`. + +**Decryption:** +- gzip → no decrypt; the package path itself is fed to `safe_tar_extract`. +- passphrase → `openssl enc -d -aes-256-cbc` with the LD5 fallback chain + (pbkdf2 iter=600000, iter=100000, no iter, md5). The output must look + like a gzip file or the next fallback runs. All four failing raises + `RuntimeError` with last-error context. +- rsa → `NotImplementedError("RSA hybrid decryption lands in task .11")`. + +**Staging creation:** +```python +staging = tempfile.mkdtemp( + prefix=".alive-receive-", + dir=os.path.dirname(os.path.abspath(target_path)), +) +``` + +**Extraction:** +- Calls `safe_tar_extract` (LD22 wrapper) which pre-validates EVERY tar + member before any disk write. Symlinks, hardlinks, absolute paths, path + traversals, device files, and oversized payloads are rejected before any + file is created in staging. +- After extraction, strips any `.alive/`, `.walnut/`, or `__MACOSX/` + directories that may have made it through (defense in depth). + +**Failure modes:** +- Tar safety violation → `ValueError("Package tar failed safety check")`. + Staging may exist but contains zero files. Cleaned up automatically. +- Decryption failure → `RuntimeError` with the last-known openssl error. +- RSA hybrid → `NotImplementedError`. + +**Recovery:** none required; failure is pre-target-mutation. + +--- + +## Step 2 — validate + +**Purpose:** confirm the package is well-formed before doing anything else. + +**Operations:** +1. Read `staging/manifest.yaml` via `read_manifest_yaml` (the LD20 + stdlib-only YAML reader in `alive-p2p.py`). +2. Run `validate_manifest` (the LD6 schema validator). Hard-fails on + missing required fields, format_version 3.x, malformed scope, malformed + files[] entries. +3. Run `verify_checksums` -- recomputes sha256 of every file listed in + `manifest.files[]` and compares against the recorded value. Mismatch + → `ValueError("Checksum verification failed: ...")`. +4. Recompute `payload_sha256` from the files[] list using + `compute_payload_sha256` and compare against the manifest field. Catches + manifest-vs-files divergence. +5. If a `signature` block is present and `--verify-signature` is set, + record a warning -- the keyring lookup defers to task .11. + +**Failure modes:** any validation error raises `ValueError` with the +detailed reason. Pre-swap, no target mutation. + +--- + +## Step 3 — dedupe-check + +**Purpose:** apply LD2 subset-of-union dedupe against the target's existing +import ledger. + +**Operations:** +1. Read `{target}/_kernel/imports.json` via `_read_imports_ledger` (returns + an empty ledger if the file or target doesn't exist yet). +2. Compute `import_id = sha256_hex(canonical_manifest_bytes(manifest))`. +3. Compute the union of all `applied_bundles` across every prior ledger + entry whose `import_id` matches this one. +4. If the requested bundle set is a subset of that union → STRICT NO-OP. + Cleanup staging, return `{"status": "noop"}` with the ledger context. +5. Otherwise compute `effective_to_apply = requested - prior_applied` and + continue. + +**Subset-of-union semantics example:** +- Receive #1 imports `[A, B]`, ledger entry records `applied_bundles=[A, B]`. +- Receive #2 of the same package with `--bundle C` adds `C`, ledger entry + records `applied_bundles=[C]`. +- Receive #3 of the same package with `--bundle A --bundle B` is a NO-OP + because the union `{A, B, C}` already covers `{A, B}`. + +**Failure modes:** none -- a corrupted ledger is treated as empty so the +receive can proceed and rebuild it. + +--- + +## Step 4 — infer-layout + +**Purpose:** determine whether the staging tree is `v2` (legacy +`bundles/` container + `_kernel/_generated/`) or `v3` (flat) so the LD8 +migration step can normalize it. + +**Precedence (LD7):** +1. `--source-layout` flag if provided AND `ALIVE_P2P_TESTING=1` env var + is set (testing-only override). +2. `manifest.source_layout` field if it equals `v2` or `v3`. +3. Structural inspection of immediate children only: + - `staging/bundles/*/context.manifest.yaml` exists → `v2` + - `staging/_kernel/_generated/` exists → `v2` + - any non-`_kernel`/non-`bundles` child has + `context.manifest.yaml` at its root → `v3` + - only `_kernel/` exists → `agnostic` (snapshot scope) +4. Otherwise: `ValueError("Cannot infer source layout. ...")`. + +**Failure modes:** unparseable layout → `ValueError`. Pre-swap, no target +mutation. Recovery: ask the sender to add a `source_layout` field to the +manifest. + +--- + +## Step 5 — scope-check + +**Purpose:** apply LD18 target preconditions. Different scopes have +different rules about target existence, parent dir presence, and walnut +identity. + +**Full / snapshot scope:** +- Target path MUST NOT exist (refuses on even an empty dir). +- Parent directory MUST exist and be writable. +- Rationale: rollback on swap failure is `shutil.rmtree(target_dir)` which + is only safe if we created it fresh. + +**Bundle scope:** +- Target walnut MUST exist with a valid `_kernel/key.md`. +- Walnut identity check: byte-compare the package's `_kernel/key.md` to + the target's. If they differ → refuse with cross-walnut grafting error. + Override via `ALIVE_P2P_ALLOW_CROSS_WALNUT=1` env var. +- Pre-swap log validation: target's `_kernel/log.md` MUST have valid YAML + frontmatter. If missing or malformed, abort here (safe abort, no swap). + +**Failure modes:** any precondition violation → `ValueError` with the +exact rule that failed. Pre-swap, no target mutation. + +--- + +## Step 6 — migrate + +**Purpose:** if the inferred layout is `v2`, run `migrate_v2_layout` on the +staging tree to reshape it into v3 form. The migration function is +documented in `migration.md`. + +**Operations:** +1. If `inferred_layout == "v2"` → call `migrate_v2_layout(staging)`. +2. The function returns a result dict with `actions`, `bundles_migrated`, + `tasks_converted`, `warnings`, `errors`. +3. If `errors` is non-empty → `ValueError("v2 -> v3 staging migration + failed: ...")`. + +**Idempotency:** running migrate against an already-v3 staging tree is a +no-op (returns a single "no-op" action). + +**Failure modes:** migration errors → `ValueError`. Recovery: see +`migration.md` troubleshooting section. + +--- + +## Step 7 — preview + +**Purpose:** print a human-readable summary of what is about to happen and +require explicit confirmation via `--yes`. + +**Preview block content:** +``` +=== receive preview === +scope: bundle +bundles: shielding-review, launch-checklist +to apply: launch-checklist +already applied: shielding-review +file count: 24 +package size: 12345 bytes +encryption: passphrase +signer: a1b2c3d4e5f67890 +sensitivity: private +renames: + launch-checklist -> launch-checklist-imported-20260407 +======================= +``` + +**Behaviour:** +- If `--yes` is passed, the pipeline proceeds immediately after printing + the preview. +- If `--yes` is NOT passed, the pipeline raises `ValueError` after the + preview is printed. The skill router or interactive caller is expected + to surface the preview, get the human's confirmation, and re-run with + `--yes`. + +**Failure modes:** missing `--yes` is a deliberate "abort and ask"; no +target mutation. + +--- + +## Step 8 — acquire-lock + +**Purpose:** prevent concurrent receive/share operations on the same +walnut. LD4/LD28 cross-platform locking. + +**Lock path:** +``` +~/.alive/locks/{sha256_hex(abspath(target))[:16]}.lock +``` + +**Strategy:** +- POSIX (fcntl available): file lock via `os.open` + `fcntl.flock LOCK_EX + | LOCK_NB`. Holder PID + timestamp written to the file. Released via + `fcntl.flock LOCK_UN` + close + unlink. +- Fallback (no fcntl): directory lock via + `os.makedirs(lock_path + ".d", exist_ok=False)`. Holder PID + timestamp + written to `holder.txt` inside the dir. Released via `shutil.rmtree`. + +**Stale-PID recovery:** +- On acquire failure, read the holder PID from the lock artifact. +- POSIX: `os.kill(pid, 0)` raises `ProcessLookupError` if dead. +- If dead → remove the lock artifact, retry once. +- If alive → refuse with actionable error including the holder PID and + the `unlock` recovery command. + +**Failure modes:** lock held by live process → `RuntimeError("busy: ...")`. +Pre-swap, no target mutation. + +**Recovery:** `alive-p2p.py unlock --walnut `. + +--- + +## Step 9 — transact-swap + +**Purpose:** apply the staged changes atomically. The exact mechanism +depends on scope. + +**Full / snapshot scope:** +- Strip the package's `manifest.yaml` from staging (it's a packaging + artifact, not walnut content). +- `shutil.move(staging, target_path)` -- atomic on the same filesystem. +- For snapshot scope: bootstrap missing `_kernel/{tasks.json, + completed.json}` with empty placeholders if the package didn't include + them. +- Rollback on failure: `shutil.rmtree(target_path)` (the target was just + created, no pre-existing content at risk). + +**Bundle scope (journaled move):** +1. Build the operations list: one `move` op per bundle to apply, with + src=`staging/{leaf}`, dst=`target/{leaf-or-renamed}`, status=`pending`. +2. Write the journal to `staging/.alive-receive-journal.json` BEFORE any + target mutation. +3. For each op: + - Mark `committing` and rewrite the journal. + - `shutil.move(src, dst)`. + - Mark `done` and rewrite the journal. +4. On failure mid-loop: + - Read the journal, find ops marked `done`. + - Reverse-rollback: `shutil.move(dst, src)` for each, in reverse order. + - Mark each `rolled_back` (or `rollback_failed`). + - PRESERVE staging by renaming to + `.alive-receive-incomplete-{iso_timestamp}` next to the target. + - Print the preserved staging path to stderr. + - Raise `RuntimeError("swap failed (bundle scope): ...")`. +5. On success: continue to step 10. + +**Failure modes:** OS-level move failure → `RuntimeError` with the cause. +For bundle scope, the journal drives rollback and staging is preserved +for diagnosis. + +--- + +## Step 10 — log-edit (NON-FATAL post-swap) + +**Purpose:** insert an import entry into `{target}/_kernel/log.md` after +the YAML frontmatter, before any existing entries (LD12). + +**Operations:** +1. Read `{target}/_kernel/log.md`. +2. Parse the frontmatter (uses regex to find the second `---` line). +3. Build the import entry from the canonical template: + ``` + ## {iso_timestamp} - squirrel:{session_id} + + Imported package from {sender} via P2P. + - Scope: {scope} + - Bundles: {bundle_list or 'n/a'} + - source_layout: {layout} + - import_id: {import_id[:16]} + + signed: squirrel:{session_id} + ``` +4. Update frontmatter `last-entry` to the new timestamp and increment + `entry-count`. +5. Atomic write: `tempfile.mkstemp` in the same dir + `os.replace`. + +**Edge cases:** +- For full/snapshot scope: log.md is brand-new, the function creates it + with canonical frontmatter + the entry. Always succeeds. +- For bundle scope: log.md must already exist with valid frontmatter + (validated in step 5). If somehow it doesn't, this step warns and the + caller appends the entry to the warnings list. + +**Failure modes (bundle scope):** any IOError or parse failure → WARN, +not fatal. The walnut is structurally correct but missing the log entry. +Recovery: `alive-p2p.py log-import --walnut --import-id `. + +--- + +## Step 11 — ledger-write (NON-FATAL post-swap) + +**Purpose:** append a new entry to `{target}/_kernel/imports.json` so +future receives can dedupe. + +**Entry schema:** +```json +{ + "import_id": "sha256-hex", + "format_version": "2.1.0", + "source_layout": "v3", + "scope": "bundle", + "package_bundles": ["a", "b"], + "applied_bundles": ["a"], + "bundle_renames": {"a": "a-imported-20260407"}, + "sender": "patrickSupernormal", + "created": "2026-04-07T10:15:00Z", + "received_at": "2026-04-07T10:16:00Z" +} +``` + +**Operations:** +1. Re-read the ledger (in case it changed during step 9). +2. Append the new entry to `imports[]`. +3. Atomic write via `tempfile.mkstemp` + `os.replace`. + +**Failure modes:** WARN, not fatal. The walnut is structurally correct +but future duplicate receives will not dedupe. Recovery: manually append +the entry shape above to `_kernel/imports.json`. + +--- + +## Step 12 — regenerate-now (NON-FATAL) + +**Purpose:** regenerate `_kernel/now.json` so the walnut's projected +state matches the new content. This is the LD1 explicit-subprocess path: +the receive pipeline does NOT rely on hook chains. + +**Operations:** +1. Resolve plugin root: `os.environ.get("CLAUDE_PLUGIN_ROOT")` or + `os.path.dirname(os.path.dirname(os.path.abspath(__file__)))`. +2. Subprocess: `[sys.executable, f"{plugin_root}/scripts/project.py", + "--walnut", target]` with `check=False`, `timeout=30`. + +**Failure modes:** WARN, not fatal. The walnut's `_kernel/now.json` is +stale. Recovery: +```bash +python3 ${CLAUDE_PLUGIN_ROOT}/scripts/project.py --walnut +``` + +The receive skill skips this step entirely if `ALIVE_P2P_SKIP_REGEN` is +set in the environment (used by tests). + +--- + +## Step 13 — cleanup-and-release (ALWAYS RUNS) + +**Purpose:** release the lock and clean up staging artifacts. Wrapped in +`try/finally` so it ALWAYS runs, even when steps 10/11/12 hit warnings. + +**Operations:** +1. Release the lock acquired in step 8 (close fd + unlink for fcntl, or + rmtree for the mkdir fallback). +2. If swap succeeded AND steps 10/11 both succeeded: delete staging dir + and journal file. +3. If swap succeeded but steps 10 OR 11 warned: rename staging to + `.alive-receive-incomplete-{iso_timestamp}` next to the target so the + journal can be inspected. The walnut itself is structurally correct. +4.

All 9 decisions take the recommended defaults; PR body must surface these for asynchronous review. + +--- + +## Q1 — Atomic swap semantics on receive (LD1, LD18) + +**Decision:** Temp-extract → validate → infer/migrate → scope-check → tentative preview → acquire-lock → canonical-dedupe-under-lock → transactional-swap → log-edit → ledger-write → regenerate-now → cleanup. Step ordering is fixed in LD1. The swap is journaled per-bundle for `scope: bundle` (`staging/.alive-receive-journal.json`); for `scope: full` and `scope: snapshot` the target did not exist pre-swap, so rollback degenerates to `shutil.rmtree(target_dir)`. + +**Rationale:** Two principles drive the order. First, project.py is invoked AFTER the swap (step 12), never against staging — running project.py over a temp dir would be wasted work, and worse, would corrupt now.json against a path that is about to disappear. Second, the lock is acquired BEFORE the canonical dedupe (step 7 before step 8) so two concurrent receives cannot both decide they need to apply the same bundles based on a stale `imports.json` snapshot. The tentative preview at step 6 is intentionally pre-lock so users see something fast; step 8 re-runs everything authoritatively under lock and aborts with "state changed during preview, re-run the command" if reality moved. + +**Open for review:** LD1 step 10/11/12 are NON-FATAL warnings that still allow exit 0 — the walnut is structurally correct even if the log entry, ledger, or now.json regen failed. This is intentional so `--auto-receive` and skill router chains continue working, but it means a silent log-edit failure leaves the walnut without an import entry until the user runs `alive-p2p.py log-import` manually. The `--strict` flag (LD19) escalates these to exit 1 for users who want fail-fast. Worth confirming Ben agrees with the default-permissive posture vs default-strict. + +--- + +## Q2 — Debounce bypass mechanism (LD1 step 12) + +**Decision:** `alive-p2p.py receive` invokes `scripts/project.py` directly via `subprocess.run([sys.executable, f"{plugin_root}/scripts/project.py", "--walnut", target], check=False, timeout=30)`. No hook chain. No `alive-post-write.sh` debounce marker manipulation. Plugin root resolution: `os.environ.get("CLAUDE_PLUGIN_ROOT") or os.path.dirname(os.path.dirname(os.path.abspath(__file__)))`. + +**Rationale:** The receive process is a CLI subprocess. Its file writes do NOT emit Claude Code `PostToolUse` events, so the `alive-post-write.sh` 5-minute debounce is structurally irrelevant — there's no hook to bypass. Trying to manipulate `/tmp/alive-project-${WALNUT_HASH}` from a subprocess context would be cargo-culting hook behavior into a context where hooks don't fire. Explicit invocation is the canonical path because it's the ONLY path; the hook chain only exists for interactive Claude Code edits. + +**Open for review:** Step 12 failures are non-fatal warns (see Q1). The recovery message tells users exactly what to run: `python3 /scripts/project.py --walnut `. Worth confirming Ben is happy with `timeout=30` for project.py — large walnuts with many bundles could plausibly exceed this. + +--- + +## Q3 — Bundle name collision policy on receive (LD3) + +**Decision:** Default REFUSE with an error listing every conflicting bundle name and its exact target path. The optional `--rename` flag enables deterministic suffix chaining: `{name}-imported-{YYYYMMDD}` first, then `-2`, `-3`, ... until a free name is found. Final chosen names are recorded in the ledger entry's `bundle_renames` map. `--merge` is NOT supported (semantic merge is out of scope). + +**Rationale:** Refuse-by-default is the safe choice — silently importing over an existing bundle with the same name is a footgun, and the user is the only one who can decide whether the incoming bundle is "the same thing" or "a different thing that happens to share a name." The deterministic chaining (vs random suffix or interactive prompt) makes the behavior predictable in CI and reproducible across receives — important for the idempotency tests in LD2. + +**Open for review:** The `--rename` flag is all-or-nothing: it applies to every conflicting bundle in one receive. There's no per-bundle "rename this one, refuse that one." If Ben wants per-bundle granularity, that's a future flag (`--rename-bundle name=newname`); not blocking the epic. + +--- + +## Q4 — Concurrent session locking (LD4, LD28) + +**Decision:** Single exclusive lock per walnut. Both share AND receive acquire it — first-come wins. POSIX strategy: `fcntl.flock(fd, fcntl.LOCK_EX | fcntl.LOCK_NB)` against `$HOME/.alive/locks/{sha256_hex(abspath(walnut))[:16]}.lock`. Windows / no-fcntl fallback: `os.makedirs(lock_dir, exist_ok=False)` against `{sha256_hex(...)[:16]}.lock.d/` with a `holder.txt` inside. Stale-lock recovery via `os.kill(pid, 0)` on POSIX, `ctypes.kernel32.OpenProcess` on Windows. Manual unstick via `alive-p2p.py unlock --walnut `. + +**Rationale:** Refusing-on-active-squirrel-session was rejected because squirrel sessions are conversational, not transactional — they may be open for hours while the user makes coffee. P2P operations are seconds-to-minutes. Blocking on session presence would make P2P feel broken. A walnut-scoped lock that BOTH share and receive respect prevents the only real race: two concurrent receives writing to the same walnut. The cross-platform split (LD28) is necessary because `fcntl` is Linux/macOS only and `os.kill(pid, 0)` is unreliable on Windows. + +**Open for review:** The lock path uses a 16-hex-char hash of the absolute walnut path so two walnuts at different paths can't collide, even if their basenames match. The hash is truncated to 16 chars (64 bits) — collision-resistant for any plausible per-user walnut count. If Ben thinks anyone will hit a birthday-paradox collision at this scale, we can extend to 32 chars; not blocking. + +--- + +## Q5 — v2 crypto compatibility window (LD5) + +**Decision:** Transparent receive of legacy v2 packages via openssl CLI fallback chain: try `-md sha256 -pbkdf2 -iter 100000` (v2.1.0 sender) → `-md sha256 -pbkdf2` (early v2) → `-md md5` (v1/pre-v2). On all three failing, hard error: `"Cannot decrypt package — wrong passphrase or unsupported format. Try openssl enc -d manually to debug."` v2.1.0 senders ALWAYS write parameters matching step 1. + +**Rationale:** A hard format break would orphan every package already in circulation across users who haven't upgraded. The fallback chain is cheap (three openssl invocations on failure path only, zero cost on the success path) and the `detect_openssl` plumbing already exists. Transparency means users don't need to know which version a package was created with — the receiver figures it out. + +**Open for review:** LD6 hard-fails on `format_version: 3.x` packages — receiver only accepts `^2\.\d+(\.\d+)?$`. This means a future v3-format-bump epic must update receivers BEFORE senders. That's intentional (forward-compat is hard, backward-compat is the priority for an installed-base-of-500+ tool) but Ben should be aware that receiver upgrades become a pre-flight for any future format change. + +--- + +## Q6 — `.alive/preferences.yaml` p2p schema (LD17) + +**Decision:** Add a top-level `discovery_hints:` key (NEW — not present on main) AND a commented `p2p:` block to `templates/world/preferences.yaml`. Schema: + +```yaml +discovery_hints: true # auto-retires after first successful operation + +p2p: + share_presets: + internal: { exclude_patterns: [...] } + external: { exclude_patterns: [...] } + relay: + url: null + token_env: GH_TOKEN + auto_receive: false + signing_key_path: "~/.alive/relay/keys/private.pem" + require_signature: false +``` + +Per-peer config (relay URL, exclude patterns, accepted state) lives in `$HOME/.alive/relay/relay.json` — NOT in preferences. `relay-probe.py` writes `state.json` (separate file), NEVER touches `relay.json`. + +**Rationale:** Two-file split because relay state is fundamentally per-user-machine (your relay URL, your keys, your peer list) while preferences are per-walnut-world (presets, defaults, opt-ins). Bundling them would force users to copy peer keys when they share `.alive/preferences.yaml` between machines. The probe's read-only stance against `relay.json` is enforced by test (LD17 — "test asserts relay.json is byte-identical before/after probe runs") so the boundary can't drift. + +**Open for review:** All `p2p.*` keys are commented out by default — opt-in only. Walnuts that don't enable P2P see zero behavior change. `discovery_hints: true` is the only key uncommented, and it's compatible with general (non-P2P) share nudges. Worth confirming with Ben that defaulting `discovery_hints` ON (vs commented-out OFF) matches the wider plugin posture. + +--- + +## Q7 — `plugin.json` version bump target (LD14) + +**Decision:** `3.0.0` → `3.1.0` (minor bump). Packages set `min_plugin_version: "3.1.0"` (advisory only — receiver doesn't hard-fail on lower). + +**Rationale:** Semver minor bump signals additive new user-visible behavior (P2P share/receive/relay skills). A patch bump (3.0.1) would understate the surface area: this epic adds three new skills, a new subprocess CLI, a new hook, and a new preferences section. A major bump (4.0.0) would overstate it: the v3 architecture itself isn't changing, no breaking removals. 3.1.0 is the honest version. + +**Open for review:** `min_plugin_version` is advisory in this epic (warn-only). If Ben wants to make it enforcing in a future release ("refuse packages from receivers below this version"), that's a one-line change in the validation pass. Not enforced now because the installed base is 3.0.0 and we don't want to break interop on day one. + +--- + +## Q8 — Signer identity model (LD20, LD23) + +**Decision:** Sender identity is the GitHub handle, resolved from `os.environ.get("GH_USER")` first, then `gh api user --jq .login` as fallback. Hard-fail if neither resolves AND the package is being signed (`--sign`) or RSA-encrypted (`--encrypt rsa`) — those modes structurally need a sender identity. Local signing key + peer public keys stored in `$HOME/.alive/relay/keys/` (LD23 keyring). Per-key identity via 16-hex-char `pubkey_id = sha256(DER-encoded-pubkey)[:16]`. NEVER base64 — hex avoids `+`/`/` copy-paste issues in CLI surfaces. + +**Rationale:** GitHub handles are already the routing primitive for the relay (`inbox//.walnut` per LD25), so reusing them as the signer identity keeps the mental model unified. Alternatives were: (a) squirrel `session_id` — too ephemeral, changes every session, doesn't survive process restart; (b) dedicated `~/.alive/relay/identity.json` — yet another piece of state to manage, and we already have GitHub handles in the relay layer. The 16-hex-char `pubkey_id` is a compromise between "long enough to avoid collisions across any plausible peer keyring" and "short enough to paste in error messages and CLI flags." + +**Open for review:** `pubkey_id` is computed from the DER form of the public key (via `openssl pkey -pubin -outform DER`), so it's stable across PEM reformatting (line wrapping, whitespace differences). Test asserts this in `test_keyring_pubkey_id_stable`. If Ben ever needs to migrate to longer or different-encoding pubkey_ids, the spec's signature `signed_bytes: "manifest-canonical-json-v1"` literal tag (LD20) lets us version-bump the canonicalization scheme cleanly. + +--- + +## Q9 — Python floor (LD22) + +**Decision:** Python 3.9+. Documented in `plugins/alive/tests/README.md`. Code style rules for the entire P2P codebase: type hints from `typing` module (`Optional`, `List`, `Dict`, `Tuple`, `Union`, `Set`, `Any`), NEVER PEP 604 `X | Y` unions or PEP 585 `list[int]` generics. F-strings (3.6+) and walrus operator (3.8+) are fine. Match statements (3.10+) are NOT used. `tarfile.data_filter` (3.12+) is OPTIONAL defense-in-depth only — the pre-validation pass is the AUTHORITATIVE safety mechanism and works on 3.9+. + +**Rationale:** Forcing 3.12+ would block local dev for everyone running 3.9 (the gap-analyst confirmed this is the actual dev environment baseline). The pre-validation pass in `safe_extractall` already guarantees "zero writes on reject" without the filter, so 3.9 has the same security posture as 3.12 — the filter is just belt-and-suspenders. Style rules exist so a future contributor doesn't accidentally drop a `dict[str, int]` annotation that breaks 3.9 imports silently. + +**Open for review:** A unit test imports `alive-p2p.py` and `walnut_paths` under Python 3.9 specifically (CI-only test if dev environment is newer). If Ben's local Python is 3.10+, this test only runs in CI. If everyone's local moves to 3.10+ in the future, we can drop the version floor in a one-line edit; it's not load-bearing on anything else in the epic. + +--- + +## Walnut-log-authoritative facts (NOT relitigated) + +These were locked in earlier P2P epics and are not part of this task.

After re-checking each against the LD6/LD20 contracts and the orchestrating brief, all five were judged non-substantive. Per the brief's 2-round hygiene rule (`Hold position on LD6/LD20 decisions ... Document and proceed if review findings are non-substantive after 2 rounds`), the task is being completed as scoped. + +| Finding | Reviewer position | Held position | Authority | +|---|---|---|---| +| `_cli` placeholder + missing `create_package` | Critical, blocks acceptance | Out of scope for .5 — deferred to .7 | Brief: "DO NOT yet add: `create_package` ... `_cli` entry point (task .7 onwards)" | +| `encryption: "none"` vs `encrypted: false` | Major, breaks v2 helper | Spec is definitive | Epic line 1387: `encryption: "none" # none \| passphrase \| rsa — LD21`.

Where the .5 task spec and the LD6/LD20 epic body differ, the epic body wins. Where the .5 task spec and the orchestrating brief differ, the brief wins (the brief is the most recent refinement, written specifically to scope the work narrowly to manifest generation/validation/YAML I/O, deferring CLI and `create_package` to .7). + +Round 1 receipt: codex session `019d66fc-84e5-7492-a561-4461e1aab015` (2026-04-07T08:18Z). +Round 2 receipt: codex session `019d670b-3198-7ae0-8949-e927c7aeb56f` (2026-04-07T08:31Z). +Both stored at `/tmp/impl-review-receipt-fn7-7cw-5.json` (overwritten by round 2). + +The defensive doc comment in `generate_manifest` (commit `a0f3e25`) acknowledges the encryption-field cross-task gap so .7 picks it up cleanly. diff --git a/plugins/alive/tests/fake_relay.py b/plugins/alive/tests/fake_relay.py new file mode 100644 index 0000000..5b80a85 --- /dev/null +++ b/plugins/alive/tests/fake_relay.py @@ -0,0 +1,141 @@ +#!/usr/bin/env python3 +"""In-memory FakeRelay for P2P round-trip tests (LD25 / fn-7-7cw.11). + +Mirrors the LD25 GitHub relay wire protocol semantics without git, network, +or process spawning.
