feat: add C, C++, Rust, Java, and Kotlin probe templates#19
Merged
Conversation
Add the Rust (file ingest) probe template: an owned AgentValue enum with From impls and an adbg! json-style macro, hand-rolled key normalization matching the shared redaction contract (Rust std has no regex), a backslash-free JSON serializer, verbatim redaction policy, 65536-byte cap, depth-64 cap, epoch-ms timestamp, 0600 append via OpenOptions, and total failure suppression. Registered as "rust" (alias "rs"), file ingest only. Cycles are unrepresentable in an owned value tree, so the live cycle fixture exercises the depth cap instead. Docs matrices and contract/e2e suites extended; live e2e compiles single-file rustc with no cargo/serde. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Add the C++ (file ingest) probe template: an owned AgentValue struct with implicit ctors from bool/long long/double/const char*/std::string plus an nlohmann-style initializer_list constructor for nested object/array literals, hand-rolled key normalization matching the shared redaction contract (no regex, ported 1:1 from the verified Rust normalizer), a backslash-free JSON serializer via ostringstream, verbatim redaction policy, 65536-byte cap, depth-64 cap, chrono epoch-ms timestamp, ofstream append with 0600 on POSIX, and total failure suppression (try/catch(...)). Registered as "cpp" (aliases "c++", "cxx"), file ingest only. Cycles are unrepresentable in an owned value tree, so the live cycle fixture exercises the depth cap instead. Docs matrices and contract/e2e suites extended; live e2e compiles single-file clang++ (g++ fallback), -std=c++17. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Add a Java (file-ingest) probe template cloning the csharp.ts approach: real java.util.regex key normalization, Map/List/array/scalar handling with a java.lang.reflect fallback over public getters and fields, IdentityHashMap-based cycle detection with a depth-64 cap, fully-qualified names (no imports) so the helper is injectable anywhere, and single-file `java <File>.java` execution.

Add the Kotlin (file ingest) probe template, closing the five-language systems batch (C, C++, Rust, Java, Kotlin). Kotlin clones the Java JVM approach: java.lang.reflect over public getters then fields (not kotlin-reflect), IdentityHashMap cycle detection, depth cap 64, real java.util.regex secret-key normalization, Files.write(CREATE, APPEND) with 0600-at-create POSIX handling, and an object AgentDebugLog.emit static helper that never alters control flow (catch Throwable). Also updates the changeset (minor bump: nine helper/runtime pairs become fourteen) and every current-facing language matrix and count (README, DESIGN, SKILL, REFERENCE, spec advertised list + region-marker row).

DESIGN.md advertised-list contradiction; C NULL-key guard on malloc failure; Rust allow attributes so user builds stay warning-free; C++ int constructor to remove the LL-suffix footgun. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
The C/C++/Rust/Kotlin fixtures compiled and ran their probe binaries
through a single `cmd /c "<compile> && <run>"` (or `sh -c`) command
string. On Windows, cmd.exe mangles the quotes of that compound string,
so every step failed with `'"...rustc.exe"' is not recognized`. Run each
step as its own shell-free Bun.spawn argv instead: a new runSteps helper
executes compile then run in order, stopping on the first non-zero exit.
Kotlin's kotlinc resolves to kotlinc.bat on Windows, which cmd.exe must
interpret, so its compile step is wrapped in `cmd /c` with the batch path
and arguments passed as separate argv elements (correctly quoted by Bun)
rather than one pre-quoted string.
Also build the C++ cyclic-drop fixture's 100-deep structure by appending
to arrayValue explicitly. `AgentValue{ __agent_cycle }` is a
single-element braced-init-list whose overload resolution differs across
compilers (Apple clang selects the initializer_list constructor and
wraps; clang 18 / gcc 13 select the copy constructor and leave a scalar),
so the nesting depth the serializer saw varied by toolchain and the
depth-64 cap only tripped locally. The explicit array wrap nests
identically everywhere, so the value is dropped on every compiler.

On Windows a just-exited process can hold an executable's file handle open for a short window after termination. The language e2e step spawns detached debug-mode daemons that run dist/debug-mode.exe; `stop` returns as soon as a daemon acks shutdown, before the OS releases the handle. The next CI step's build:binary then races that release and fails with `EACCES: permission denied, rm '...\dist'`, failing the Distribution and System test steps. Retry the dist removal with a short backoff (up to ~5s) on EACCES/EPERM/EBUSY so the rebuild proceeds once the handle is freed; other platforms release handles on exit and still succeed on the first attempt.

Extend ProbeTemplates with a dataEncoding discriminator
("native-json-value" | "serialized-json") and machine-readable placement
metadata for the helper and call insertion points. Every existing renderer
declares metadata matching today's behavior (native-json-value; helper
file-start for C/C++, top-level elsewhere). The template command surfaces
the new fields via JSON passthrough, and the pretty renderer prints a data
encoding and placement section.

Replace the Rust helper's recursive AgentValue model, adbg! macro, depth handling, and client-side secret redaction with a small `mod agent_debug_mode` that only escapes envelope metadata, timestamps, bounds, and appends. The call template now accepts a serialized-JSON expression (__DATA_JSON_EXPRESSION__), and json_string provides the escaped-text fallback. The daemon performs redaction, so serialized-json callers may write raw caller text to the incoming file. Helper drops from 260 to 96 nonblank lines (63% smaller). Runtime coverage: raw arrays/strings/numbers/booleans/null passthrough, json_string escaping torture, malformed-JSON rejection, oversize drop, concurrent append, metadata with control characters, and a realistic insertion fixture with nested modules and an application type named AgentValue proving symbol isolation. The cycle and shared-reference cases (client-side value model) are removed for serialized-json fixtures and retained for the rest. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Replace the C++ helper's recursive AgentValue model, AgentKind enum, initializer-list object detection, depth handling, and client-side secret normalization/redaction with a small `namespace agent_debug_mode` that only escapes envelope metadata, timestamps, bounds, and appends. The call template now accepts a serialized-JSON expression (__DATA_JSON_EXPRESSION__); json_string provides the escaped-text fallback and AGENT_DEBUG_STRINGIFY builds a __FILE__ ":" __LINE__ location. The POSIX append ports C's atomic open(O_WRONLY|O_APPEND|O_CREAT, 0600) with an ofstream fallback under _WIN32, and catch(...) suppresses every failure. The daemon performs redaction, so serialized-json callers may write raw caller text to the incoming file. Helper drops from 297 to 113 nonblank lines (62% smaller). Runtime coverage mirrors Rust: raw arrays/strings/numbers/booleans/null passthrough, json_string escaping torture, malformed-JSON rejection, oversize drop, concurrent append, metadata with control characters, and a realistic insertion fixture with a namespace and an application type named AgentValue proving symbol isolation. The cycle and shared-reference cases (client-side value model) are removed for the serialized-json cpp fixture. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Replace the C probe's allocated AgentValue pointer tree, adbg_* variadic builders, recursive serializer, depth handling, and secret-key redaction with a raw-JSON passthrough emitter that mirrors the migrated Rust and C++ templates. The caller now supplies one complete serialized JSON value; the helper only escapes envelope metadata, stamps the timestamp, enforces the 65,536-byte cap, and atomically appends. Symbols carry a distinctive agent_debug_ prefix in place of the removed generic global names. The generated helper drops from 538 to 142 nonblank lines (74% smaller).

Document the migrated native probe contract across the agent-facing docs: the native-json-value vs serialized-json data encodings and their __DATA_EXPRESSION__ / __DATA_JSON_EXPRESSION__ placeholders, the json_string escaped-text fallback, the caller's no-secrets responsibility (daemon redaction is defense-in-depth; Rust/C++/C do no client-side redaction), the file-start vs top-level helper placement and statement call placement, per-language region markers, and application/x-ndjson as the actual HTTP content type. Java, Kotlin, and the other languages with a safe standard serializer keep native structured values. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

The injected helper's `#define _POSIX_C_SOURCE` cannot take effect when a real application file includes system headers (e.g. <stdio.h>) before the helper: glibc's <features.h> locks the feature-test macros on first inclusion, so under strict -std=c99 clock_gettime, CLOCK_REALTIME, and struct timespec stay hidden and the file fails to compile on Linux (macOS libc exposes them regardless). Gate the clock_gettime path on CLOCK_REALTIME's preprocessor visibility (which shares the __USE_POSIX199309 guard with clock_gettime and struct timespec) and fall back to ISO C time(NULL)*1000 when it is unavailable, keeping millisecond precision wherever the POSIX clock API is visible.

requestDaemonShutdown returned as soon as the daemon stopped answering health checks (its listener socket closed), but on Windows the process briefly outlives that moment while it unwinds and the OS releases the mandatory locks it holds on files under the daemon home. Callers -- the stop command and integration tests -- delete that home directory the instant shutdown returns, racing the dying process and failing with EBUSY/EACCES, or EFAULT under Bun's recursive rm. This surfaced as chronic windows-2025 flakiness where a different daemon test's afterEach rm failed each run. Wait (bounded by the existing 5s shutdown deadline) for the recorded process to actually exit on win32, verified by process identity so a reused pid cannot be mistaken for the daemon. This is a single synchronization point that also makes the stop command synchronous on Windows. POSIX has no mandatory locks and returns as soon as health is down -- behavior unchanged. Also harden retryOnWindowsLock: treat EFAULT as a transient lock code and widen the budget (25 attempts, escalating backoff capped at 200ms) so a just-exited binary's lock-release window is covered, fixing the npm-install EBUSY timeout.

The win32 wait added to requestDaemonShutdown polled inspectProcess for the recorded pid to exit. Integration tests that run the daemon in-process via startDaemonServer record the current process's pid, which never exits, so the wait spun to the 5s deadline and timed out the SSE backpressure test. A real daemon is always a separate spawned process, so skip the wait when the recorded pid is our own -- closing the listener is all an in-process server can observe.

Helpers carry only envelope construction, timestamp, 65536-byte cap, a control-character/NDJSON-framing guard, and secure 0600 append — 63%/62%/74% smaller than the initial value-model helpers (Rust 96, C++ 113, C 142 nonblank lines, all under the 150 cap).Verification
