engram: WAL persistence + integrity hardening + single canonical runtime
El SDK CI - dev / build-and-test (pull_request) Failing after 13m17s

Establish lang/runtime/ as the ONE canonical el runtime (from the active
runtime that carries hebb/emb persistence + the new WAL); repoint the el CI
publish, engram build, elb default, and in-repo build scripts to it; delete
the el-compiler/runtime + lang/releases/ forks; add scripts/check-single-runtime.sh
drift guard.

Fixes a live prod bug: the el CI published el-runtime-c/-h from the LAGGING
el-compiler fork (0 hebb refs), so the shipped soul never persisted Hebbian
edge weights — learned co-activation was wiped on every restart. Publishing
from canonical ships the stranded 'learning that cannot outlive the process'
fix.

WAL storage engine + integrity fixes (DELETE->tombstone + store-layer
protection, safe data-dir default) ride in behind ENGRAM_WAL (default off =
byte-identical to today). Verified: engram elb per-module build clean, WAL
gate 66/66, native smoke ok, drift-guard green.

/*
* el_runtime.h — El language C runtime header
*
* Declares all built-in functions available to compiled El programs.
* Include this in every generated .c file.
*
* Value model:
* All El values are represented as el_val_t (= int64_t).
* On 64-bit systems a pointer fits in int64_t.
* String values are cast: (el_val_t)(uintptr_t)"hello"
* Integer values are stored directly.
* This lets arithmetic work naturally while still passing strings around.
*
* Type conventions (El -> C):
* String -> el_val_t (holds const char* via uintptr_t cast)
* Int -> el_val_t
* Bool -> el_val_t (0 = false, nonzero = true)
* Any -> el_val_t
* Void -> void
*
* Macros for convenience:
* EL_STR(s) cast string literal to el_val_t
* EL_CSTR(v) cast el_val_t back to const char*
* EL_INT(v) identity — el_val_t is already int64_t
* EL_NULL null / zero value
* EL_FALSE boolean false (0)
* EL_TRUE boolean true (1)
*
* Link requirements:
* -lcurl — required for the HTTP client (http_get, http_post, llm_*).
* -lpthread — required for the HTTP server (one detached thread per
* connection, capped at 64 concurrent).
* -loqs — optional; required only when liboqs is installed and the
* pq_* / sha3_256_hex entry points are needed. Detected at
* compile time via __has_include(<oqs/oqs.h>).
* -lcrypto — optional; pulled in alongside -loqs. Used for X25519 in
* pq_hybrid_* and HKDF-SHA256 derivation.

*
* A Calendar interprets an Instant under a particular cycle convention and

* (or sol/phase, or cycle/phase, depending on kind).
*
* Storage convention: Calendar / CalendarTime / Rhythm / LocalDate /
* LocalDateTime are heap-allocated structs whose pointers are cast into
* el_val_t. A 24-bit magic header at offset 0 lets the runtime identify
* the kind safely. LocalTime is small enough to live in the int64 slot
* directly (nanos since midnight, signed). */

/*
* el_runtime.h — El language C runtime header
*
* Declares all built-in functions available to compiled El programs.
* Include this in every generated .c file.
*
* Value model:
* All El values are represented as el_val_t (= int64_t).
* On 64-bit systems a pointer fits in int64_t.
* String values are cast: (el_val_t)(uintptr_t)"hello"
* Integer values are stored directly.
* This lets arithmetic work naturally while still passing strings around.
*
* Type conventions (El -> C):
* String -> el_val_t (holds const char* via uintptr_t cast)
* Int -> el_val_t
* Bool -> el_val_t (0 = false, nonzero = true)
* Any -> el_val_t
* Void -> void
*
* Macros for convenience:
* EL_STR(s) cast string literal to el_val_t
* EL_CSTR(v) cast el_val_t back to const char*
* EL_INT(v) identity — el_val_t is already int64_t
*
* Link requirements:
* -lcurl — required for the HTTP client (http_get, http_post, llm_*).
* -lpthread — required for the HTTP server (one detached thread per
* connection, capped at 64 concurrent).
* -loqs — optional; required only when liboqs is installed and the
* pq_* / sha3_256_hex entry points are needed. Detected at
* compile time via __has_include(<oqs/oqs.h>).
* -lcrypto — optional; pulled in alongside -loqs. Used for X25519 in
* pq_hybrid_* and HKDF-SHA256 derivation.
*
* Canonical compile command:
* cc -std=c11 -I el-compiler/runtime -lcurl -lpthread \
* -o <out> <prog>.c el-compiler/runtime/el_runtime.c
*
* With liboqs (post-quantum stack):
* cc -std=c11 -I el-compiler/runtime -lcurl -lpthread -loqs -lcrypto \
* -o <out> <prog>.c el-compiler/runtime/el_runtime.c

# El Compiler Release v1.0.0 — 2026-05-02
## Components
- `bootstrap.py` — El language compiler (Python, recursive descent parser, emits C)
- `el_runtime.c` — El runtime (C, HTTP server, engram, DHARMA, LLM chain)
- `el_runtime.h` — Runtime public API header
## Changes in this release
### Critical bug fixes
- `state_set`/`state_get` are now thread-safe (pthread_mutex). Was racing across 64 worker threads.
- `looks_like_string` threshold raised from 1,000,000 to 4GB. Unix timestamps were being dereferenced as heap pointers.
- `fs_read` guards against negative `ftell` result (pipe/special file overflow).
### Engram architecture (major)
- Two-layer activation: `background_activation` (Layer 1, broad fan-out) + `working_memory_weight` (Layer 2, executive filter)
- Inhibitory edges: `EngramEdge.inhibitory` flag suppresses working memory promotion without affecting background activation
- Suppression memory: `suppression_count` — nodes activated-but-suppressed accumulate pressure toward breakthrough
- Temporal decay: `temporal_decay_rate`, `created_at`, `last_activated_at`, `activation_count` on EngramNode
- Per-type activation thresholds (Safety: 0.05, Canonical: 0.15, Lesson: 0.25, Note: 0.40)
- Temporal range query: `engram_query_range(start_ms, end_ms)`
- Layered consciousness: `EngramLayer` struct, `layer_id` on nodes and edges, `EngramStore.layers[]`
- Layer 0 override pass: safety layer fires last and cannot be suppressed

* Engram WAL (write-ahead log) + compaction + integrity hardening.
*
* Design: docs/architecture/design/engram-storage-engine-wal.md §§3-14, §18.
* Whole feature is gated behind ENGRAM_WAL=on (default off byte-identical
* to the snapshot-as-store behavior). When on, structural mutations append a
* framed, CRC'd record to <dir>/engram.wal instead of rewriting the full
* snapshot; boot replays the WAL over the base snapshot; a size threshold
* triggers compaction (fresh snapshot + WAL truncate).
*
* Record framing (little-endian native; single-machine prototype):
* [u32 magic 'EWL1'][u32 payload_len][u8 op][u8 flags][u64 lsn]
* [u32 crc32][payload]
* crc32 covers op|flags|lsn|payload. A record whose magic/length/crc fails
* validation marks end-of-valid-log (torn tail from a crash replay stops
* cleanly, never crashes).
