Canonical Gate Identity

July 18, 2026

A second review found the unaccounted-gates hard-fail shipped the prior session compared gate names as exact strings — fixed with a canonical gate_id registry, removed the trapdoor escape hatch, and versioned enforcement so 150 real historical sessions don't retroactively fail

OSGatesTesting

distinct gate-name STRINGS found across ~150 real session JSONs, for what is actually only ~21 real gates — the real scale of the naming-drift problem, measured not assumed

of the prior session's 19 flagged sessions confirmed as REAL unaccounted-gate gaps once canonical resolution is applied — 6 were naming-drift false positives, exactly as the review predicted

of 150 real historical sessions hard-fail on gate accounting under the new logic — verified via the real CLI against every session file, not just the pure-function scan

new tests across 2 new files (gate-registry.test.mjs: 15, gate-accounting.test.mjs: 13) plus 8 rewired CLI-wiring tests in the existing gate-audit file

1010

build-session.mjs's final line count, down from 1045 at session start (1100 is the hard limit) — a real reduction from extraction, not just code moved sideways

Timeline

Start

Charge: fix the gate-accounting hard-fail's unverified string-comparison design, remove the escape-hatch trapdoor, version enforcement

Crucible

Council (architect/engineer/qe) unanimous ship-it on the core design; one real tension on escape-hatch removal, resolved via gates_missed already being the correct path

Evidence first

Enumerated every real gate-name string across ~150 session JSONs before designing anything — found 66 strings for ~21 real gates, and a genuine sub-case (prose sentences, not gate names) the Council hadn't anticipated

Decision point

Asked Zeb directly how to treat prose-sentence entries — grandfather as unresolved/legacy-warn, no auto-migration guessing

Build

gate-registry.mjs (canonical ids + verified aliases) and gate-accounting.mjs (versioned reconciliation logic) built, extracted from build-session.mjs

Real bug found

Registry self-audit found a real ambiguous case: 'Dependency Gate / Environment & Config Gate' genuinely refers to BOTH gates as a pair in real sessions — deliberately left unresolved rather than force-aliased to one

Verification

Ran the real CLI against all 150 historical sessions (not just the pure-function scan) — 0 crashes, 0 gate-accounting hard-fails, exactly matching the version-boundary design

Test-suite repair

The prior session's gate-audit test file broke against the new architecture (mutation tests targeted inline code that no longer exists) — fixed by re-scoping tests to the correct layer (pure function vs. CLI wiring)

Done

102 total OS tests passing across 9 files, docs updated (triggers.md, ignition.md, _SCHEMA.md), build-session.mjs down 35 lines

What shipped

forgekit-os/scripts/gate-registry.mjs — canonical gate_id registry, 21 gates, aliases sourced from a verified grep of real historical session JSONs (not invented)

forgekit-os/scripts/gate-accounting.mjs — session_audit validation extracted from build-session.mjs, gate_accounting_policy-versioned (legacy sessions warn, 'canonical-v1' sessions hard-fail)

REMOVED: audit.unaccounted_gates_accepted — the escape hatch that let a session accept the ABSENCE of gate accounting. gates_missed + a reason remains the correct, unchanged path for a consciously-skipped gate.

forgekit-os/scripts/tests/gate-registry.test.mjs — 15 tests including a real-data verification that every registered alias actually appears in a real historical session (no invented aliases)

forgekit-os/scripts/tests/gate-accounting.test.mjs — 13 tests including a real historical audit reclassifying the prior session's 19 flagged sessions: 13 genuine gaps, 6 naming-drift false positives

Rewrote build-session-gate-audit.test.mjs's gate-accounting-related tests to match the new architecture — CLI-wiring tests instead of duplicated policy-invariant tests (those now live in gate-accounting.test.mjs), and a mutation test fixed to target the actual new location of the logic

Documentation: triggers.md's Session Contract template + a new Trigger Map row for gate-registry maintenance, ignition.md's session_contract template, _SCHEMA.md's Session Audit section — all updated to describe gate_accounting_policy and the new reconciliation design

“lets wrap the current session and then start the new session in the same conversation”
