1) Definition Lock (FenceOS)

FenceOS (LOCKED): boundary/actuation control preventing irreversible threshold crossings using TTC/buffer/rate-dominance; triggers truncation & stitching (APRC) via:

$R = \dot{D} / \dot{G}$ R=D˙/G˙
$T T C = B / (- \dot{B})$ TTC=B/(−B˙)
$Θ = T T C / T_{repair}$ Θ=TTC/Trepair
$Λ = T_{enforce} / T T C$ Λ=Tenforce/TTC

2) Node Scope (what this instance covers)

Node: {{Place×Lane×Zoom}}
Lane meaning in this place: {{1–2 lines describing lane}}
Boundary meaning: {{what “irreversible crossing” means here}}
Protected core links (if applicable): {{list P lanes affected}}

3) Boundary Specification (the fence line)

3.1 Failure boundary metric $x (t)$ x(t)

Choose a measurable metric that approaches a limit as failure nears.

$x (t) =$ x(t)= {{metric name}}
Interpretation: {{what rising x means}}

3.2 Threshold $x^{*}$ x∗ (fence line proxy)

$x^{*} =$ x∗= {{threshold value or condition}}
Why it represents irreversibility: {{one sentence}}

3.3 Buffer thickness

$B (t) = x^{*} - x (t)$ B(t)=x∗−x(t)

(Flip sign if “higher is better.”)

3.4 Buffer erosion

$\dot{B} (t) \approx \frac{B (t) - B (t - Δ t)}{Δ t}$ B˙(t)≈ΔtB(t)−B(t−Δt)

Use smoothing: {{moving average window}}.
\dot{B}(t)\approx \frac{B(t)-B(t-\Delta t)}{\Delta t}
]
Use smoothing: {{moving average window}}.

4) TTC + Rate Dominance (core computations)

4.1 TTC

$T T C = \frac{B}{- \dot{B}} (\dot{B} < 0)$ TTC=−B˙B(B˙<0)

4.2 Damage and regeneration rates

Define:

$\dot{D} (t)$ D˙(t) = {{bad event rate}}
$\dot{G} (t)$ G˙(t) = {{repair completion rate}}

Compute: $R = \frac{\dot{D}}{\dot{G} + ϵ}$ R=G˙+ϵD˙

4.3 Repair time constant and enforcement lag

$T_{repair} =$ Trepair= {{median/90p repair time}}
$T_{enforce} =$ Tenforce= {{detection→effect delay}}

Compute: $Θ = \frac{T T C}{T_{repair}} Λ = \frac{T_{enforce}}{T T C}$ Θ=TrepairTTCΛ=TTCTenforce
\Lambda=\frac{T_{\text{enforce}}}{TTC}
]

5) Bands + Stop-Loss Policy (FenceOS v1.0)

5.1 Default bands (tune later)

R bands

Green ≤ 0.8
Amber (0.8..1.0]
Red > 1.0

Θ bands

Green ≥ 1.5
Amber [1.0..1.5)
Red < 1.0

Λ bands

Green ≤ 0.7
Amber (0.7..1.0)
Red ≥ 1.0

5.2 Trigger rule (LOCK)

TRUNCATE if:

$R > 1$ R>1 OR $Θ < 1$ Θ<1 OR $Λ \geq 1$ Λ≥1

5.3 Hysteresis (LOCK)

Relax only if:

all metrics Green for window $W = d u r a t i o n$ W=duration
and buffer rebuild:

$B \geq B_{m i n} + Δ B_{h y s t}$ B≥Bmin+ΔBhyst

6.1 Primary sensors (required)

S1: $x (t)$ x(t) (boundary metric)
S2: $B (t)$ B(t) (buffer)
S3: $\dot{B} (t)$ B˙(t) (erosion)
S4: $\dot{D} (t)$ D˙(t) (damage events)
S5: $\dot{G} (t)$ G˙(t) (repairs)
S6: TTC
S7: $R, Θ, Λ$ R,Θ,Λ

6.2 Secondary sensors (optional but useful)

coupling indicators (to/from other lanes)
volatility/variance measures (phase turbulence proxy)
operator fatigue / capacity slack measures (if human-heavy lane)

7) Actuation Menu (what fences exist here)

List available fences in this lane at this zoom:

7.1 Soft fences

{{SOFT_1}}
{{SOFT_2}}

7.2 Hard fences

{{HARD_1}}
{{HARD_2}}

7.3 Reroute / Decouple actions

{{REROUTE_1}}
{{DECOUPLE_1}}

7.4 Truncation action (APRC)

{{what “stop normal mode” means here}}

7.5 Stitching action

{{how reopening/reentry is staged}}

8) Coupling (how this node affects others)

8.1 Coupling out (this lane → others)

Specify coupling strengths $K_{t h i s \to j} \in [0, 1]$ Kthis→j∈[0,1]:

K_this→{{LaneA}} = {{0..1}}
K_this→{{LaneB}} = {{0..1}}

8.2 Coupling in (others → this lane)

K_{{LaneC}}→this = {{0..1}}

8.3 Protected core set $P$ P impact

List which core lanes this node threatens if it fails:

{{HEALTH/FOOD/GOV/SAFETY/ENERGY/EDU}}

9) ChronoHelmAI Execution Block (optional but recommended)

9.1 Lane State Record (LSR) format

			
LSR: {{Place×Lane×Zoom}}
  B: {{...}}
  dBdt: {{...}}
  TTC: {{...}}
  R: {{...}}
  Theta: {{...}}
  Lambda: {{...}}
  Band: {{...}}
  RecommendedActions: {{...}}

		

9.2 Action Token (AT) template

			
AT: {{Place×Lane×Zoom}}×Operator×Fence.{{ACTION}}×v1
WHEN: {{t0..t1}}
WHY: {{R,Theta,Lambda,TTC summary}}
DO: {{action steps}}
VERIFY: {{expected signal changes + deadlines}}
EXIT: GreenWindowW + Hysteresis(B >= Bmin + dB_hyst)

		

10) Failure Mode Trace (required, schematic)

Write as a non-emotive chain:

{{upstream cause}} → B shrinks → TTC compresses → Θ<1 or Λ≥1 → late fence → boundary crossed → repair time constant explodes → collapse mode escalates

11) Minimal “Spec Block” (single copy block)
